Peter Gregory discusses user account configuration data; including, editing, and deleting person debts with Admintool and shell commands; user shells; and user account instructions in Solaris eight.
This pattern chapter is excerpted from solar licensed system Administrator for Solaris eight examine ebook, by pass of Peter Gregory.This chapter is from the ebook
After finishing this chapter, you will be able to
determine here login procedures: log birthright into a equipment, log off of a device, and change login passwords.
State the command used to identify which users are at present logged into the gadget.
State the steps required to create consumer bills on the autochthonous gadget the usage of the admintool utility.
State the command syntax so as to add, modify, or delete consumer/neighborhood accounts on the autochthonous tackle with the useradd, groupadd, usermod, groupmod, userdel, or groupdel commands.
Given a user's login shell, list the shell initialization info used to deploy a user's travail environment at login.
to meet these targets, this chapter discusses:
consumer account configuration data;
including, modifying, and deleting user bills with Admintool;
including, enhancing, and deleting user accounts with shell commands;
person shells; and
user account commands.
Three primary information define the id of a consumer account: the password file, the shadow file, and the community file.The Password File
The password file contains the primary making a selection on suggestions for each and every consumer allowed to entry a system. The gadget vicinity of the password file is /and many others/passwd. The format of the password file is:username:password:uid:gid:gcos-field:home-dir:login-shell
These fields are:
username—the identify that identifies the consumer account.
password—in Solaris eight an "x" in this box signifies that the corresponding shadow file includes the encrypted password string.
uid—the spirited numerical identity assigned to the account. The optimum expense for UID is 2147483647, but directors are urged to use values below 60,000 to be inevitable compatibility with the entire tools that are used to manage money owed or panoply tips that includes usernames.
gid—the basic (default) numerical neighborhood identification assigned to the account. dote the UID field, the highest cost for GID is 2147483647, but a maximum of 60,000 is preferable.
gcos-field—here's the person's true identify (the time term "gcos-box" is the historical term for this container).
domestic-dir—the directory where the user is placed after logging in; this constantly includes the user's own files and directories.
login-shell—the prefatory shell it really is started on behalf of the user upon logging in. If this box is blank, then /usr/bin/sh is used.
The password file can be examine by anyone on the equipment. There isn't any information that own to be stored surreptitious in this file. A sample password file feels dote this:root:x:0:1:super-user:/:/sbin/sh daemon:x:1:1::/: bin:x:2:2::/usr/bin: sys:x:three:three::/: adm:x:four:4:Admin:/var/adm: lp:x:seventy one:8:Line Printer Admin:/usr/spool/lp: uucp:x:5:5:uucp Admin:/usr/lib/uucp: nuucp:x:9:9:uucp Admin:/var/spool/uucppublic:/usr/lib/uucp/uucico listen:x:37:four:community Admin:/usr/internet/nls: pete:x:a hundred:4:Peter Gregory:/export/home/pete:/bin/sh no one:x:60001:60001:no one:/:
Fields within the password file are delimited with the aid of colons (":"), and antiseptic fields are signified through two adjoining colons ("::"). as an example, be sensible that the account identify container for daemon is clean—simply two colons. additionally, daemon has no shell entry, so the ultimate character for daemon is the colon delimiter.
The colon delimiter is additionally used within the shadow and community info, that are mentioned in a later area.
it is viable and permissible to create a yoke of username within the password file with the equal UID. every username may own its personal wonderful password. despite the fact, tools comparable to ls and ps, when used with alternatives exhibiting username, will monitor the first username create in the password file matching the UID.
When a unusual account is brought, changed, or eliminated with the useradd, usermod, or userdel instructions (that are discussed later in this chapter), the gadget creates a backup copy of the password file, called /etc/opasswd.The Shadow File
The shadow file carries every consumer account's encrypted password, as well as specific per-account parameters governing "password aging." The gadget location of the shadow file is /etc/shadow. The format of the shadow file is:username:password:lastchg:min:max:warn:inactive:expire:flag
These fields are:
username—here is the equal username present in the password file.
password—a 13-character encrypted password. If this box consists of a lock string (e.g., "locked" or "NP"), the account is inaccessible; if blank, the account has no password.
lastchg—date of closing password trade (actually the variety of days between January 1, 1970, and the date the password become terminal modified).
min—minimum variety of days allowed earlier than the password may besides be modified.
max—optimum number of days allowed before the password expires.
warn—the number of days earlier than expiration that the consumer is warned.
inactive—the variety of days of condition of being idle allowed for the account before the account is immediately locked.
expire—the date when the user account is deactivated.
flag—a container reserved for future use.
The shadow file is restricted so that most efficient the tackle administrator can study it. here's because an interloper could role a "dictionary assault," the usage of guessable passwords in an try to assess the passwords for one or extra money owed. classes that "crack" account passwords are available for this goal; as a result, the shadow file isn't publicly readable.
A pattern shadow file feels dote this:root:Pe0iQfp2LcAig:10528:::::: daemon:NP:6445:::::: bin:NP:6445:::::: sys:NP:6445:::::: adm:nIP3GPx2FIZYQ:11053:::::: lp:NP:6445:::::: uucp:NP:6445:::::: nuucp:NP:6445:::::: hear:*LK*::::::: pete:GSSUYVrJ8EKyA:11055:::::: nobody:NP:6445::::::
note that one of the crucial money owed within the instance shadow file own "NP" ("no password") or "*LK*" (locked) in them. These are only two approaches of signifying that the bills are locked towards login. there's nothing truly magic about "NP" or "*LK*"—they are just one pass of effectively displaying that these accounts are locked and going to abide that way. You could build other text within the password box to suit your wants; for instance, a helpdesk ticket quantity or a date.
When a consumer adjustments his or her password, the gadget creates a backup reproduction of the shadow file, referred to as /etc/oshadow. This additionally happens if root adjustments a consumer's password.
feel About It . . .
Why are encrypted passwords present in /etc/shadow and never in /and many others/passwd?
for many commands (ps, ls, and so forth.) to travail properly, /etc/passwd should be world readable. ahead of using /etc/shadow, utter clients' encrypted password strings were additionally publicly readable. This gave americans with "password cracking" courses a casual to determine different users' passwords. by relocating the encrypted password strings to /and so on/shadow (which may besides be study simplest with the aid of root), the means to entry encrypted passwords is eradicated.
First, a Little bit of background. Older versions of UNIX did not own a shadow file; instead, the encrypted password string become present in the password file, within the 2d box it really is usually stuffed with an "x" in Solaris. Solaris noiseless supports the encrypted password acting in the password file, although this is no longer really useful, for the intuition that the password file is publicly readable.
Older versions of UNIX with out a shadow file additionally had no password-getting dilapidated capability.
The network tips system (NIS) subsystem turned into designed around the dilapidated shadow-much less architecture; this explains why NIS has no shadow map, nor does it sheperd password ageing.The neighborhood File
The group file carries a listing of the entire groups on the device, together with each and every group's numeric groupid and an inventory of each of the usernames which are secondary members of each and every community. The region of the group file is /and so on/community. The layout of the neighborhood file is:groupname:password:gid:person-checklist
These fields are:
groupname—this is the cognomen of the neighborhood.
password—this is an not obligatory password for the community.
gid—the spirited numerical identity assigned to the community. The optimum value for GID is 2147483647, but administrators are advised to gain use of values less than 60,000 to gain inevitable compatibility with utter of the tools which are used to control money owed or expose tips that comprises neighborhood names.
user-list—a comma-separated record of users allowed in the group. These businesses are clients' secondary community IDs.
A pattern group file follows.root::0:root other::1: bin::2:root,bin,daemon sys::three:root,bin,sys,adm adm::four:root,adm,daemon uucp::5:root,uucp mail::6:root tty::7:root,tty,adm lp::eight:root,lp,adm nuucp::9:root,nuucp team of workers:GSSUYVrJ8EKyA:10:pete daemon::12:root,daemon sysadmin::14: no one::60001: noaccess::60002: nogroup::65534:
be sensible the password sphere in the community "team of workers." groups can be password included through inserting a password string into the password box. observe, though, that this is a very sheperd manner; there are no tackle supplied to region the group password in for you.
trace: that you may Take a password string from the shadow file and use the vi editor to splice it into the community file. The group password will be the equal as the account password from the shadow entry the region you took the password string.
When a group is password protected, any one who is not a member of the neighborhood could be challenged for the neighborhood's password when they've entered the newgrp command.simple and Secondary Groupids
each and every consumer account has one fundamental groupid—here is the community defined in the password file. When a person logs on, here is his or her associated groupid.
each and every consumer account besides has zero or more secondary groupids. A person's secondary corporations are those community entries that comprise the username of their lists of contributors.
There are some efficient obstacles of groupids. as an instance, each user account may besides be in no greater than sixteen organizations, and a line in the neighborhood file can't exceed 512 characters (together with the newline persona).
What happens if you should add so many individuals to a gaggle that you just exceed the 512-personality entry limit? You simply create a different replica community entry—identical identify and community quantity—and list the extra individuals there.
The primary and secondary groupids at once impress file gadget entry permissions, which is explored thoroughly in Chapter 10.
consider About It . . .
What often is the sequel if a username own been brought to a gaggle file entry when that group was the consumer's primary neighborhood?
The additional entry would own no impact, considering the person is already configured for the fundamental neighborhood membership in the /and so on/passwd file.the root Account
the foundation account has particular privileges on a equipment: Root is permitted to study and write every file on a system, in spite of the file's ownership and authorization settings. system directors log in with the root account that allows you to operate administrative initiatives.
the root account gets its power and privilege from the cost of its user number: Root is person quantity zero, described in the password file.
think About It . . .
What could be the consequences of changing a typical consumer's person quantity to zero? What potential could there be of inserting root's entry at the conclusion of the passwd file (in its region of the starting)?
altering a regular person's consumer number to zero gives the consumer root privileges.
One skills of inserting root on the conclusion of the password file is that if an interloper is in a position to adjust the password file to give another user root privilege (see the first question here), then output from commands equivalent to ls and ps would exhibit that different person because the owner of root strategies and data.

Disks are divided into regions called “disk slices” or “disk partitions.” A slice is composed of a single ambit of contiguous blocks. It is a physical subset of the disk (except for slice 2, which represents the entire disk). A UFS or the swap belt is built within these disk slices. The boundaries of a disk slice are defined when a disk is partitioned using the format utility, and the slice information for a particular disk can be viewed by using the prtvtoc command. Each disk slice appears to the OS (and to the system administrator) as though it were a divorce disk drive.
Disk slicing differs between the SPARC and x86 platforms. On the SPARC platform, the entire disk is devoted to the OS; the disk can be divided into 8 slices, numbered 0 to 7. On the x86 platform, the disk is divided into fdisk partitions using the fdisk command. The fdisk partition is divided into 10 slices, numbered 0 to 9.
A physical disk consists of a stack of circular platters. Data is stored on these platters in a cylindrical pattern called “cylinders” as illustrated in figure 4-1. Cylinders can be grouped and isolated from one another. A group of cylinders is referred to as a slice. A slice is defined with start and cessation points, starting from the outside of the platters to the hub of the stack of platters, which is called the “spindle.”
For example, a 73GB SCSI disk has 14,087 cylinders, numbered 0 to 14,086. Cylinder 0 is on the outside edge of the platters, and cylinder 14,086 is the closest to the spindle. Disk slices are defined by an offset and a size in cylinders. The offset is the distance from cylinder 0. To define a slice, the administrator provides a starting cylinder and an ending cylinder. A slice spanning from cylinder 0 to 14,086 would use the entire disk and is typical of the slicing scheme used on a ZFS boot disk.
When setting up slices, recall these rules:
When they dispute ZFS in Chapter 5, you’ll learn how to salvage around some of these limitations in file systems.Displaying Disk Configuration Information
As described earlier, disk configuration information is stored in the disk label. If you know the disk and slice number, you can panoply information for a disk by using the print volume table of contents (prtvtoc) command. You can specify the volume by specifying any slice defined on the disk (for example, /dev/rdsk/c0t3d0s2 or /dev/rdsk/c0t3d0s*). Regardless of which slice you specify, utter slices defined on the disk will be displayed. If you know the target number of the disk but finish not know how it is divided into slices, you can note information for the entire disk by specifying either slice 2 or s*. The following steps note how you can examine information stored on a disk’s label by using the prtvtoc command.
Type the following text and press Enter.# prtvtoc /dev/rdsk/c2t0d0s2<cr>
The system responds with the following:* /dev/rdsk/c2t0d0s2 partition map * * Dimensions: * 512 bytes/sector * 424 sectors/track * 24 tracks/cylinder * 10176 sectors/cylinder * 14089 cylinders * 14087 accessible cylinders * * Flags: * 1: unmountable * 10: read-only * * Unallocated space: * First Sector Last * Sector signify Sector * 0 10176 10175 * * First Sector Last * Partition Tag Flags Sector signify Sector Mount Directory 0 2 00 10176 143339136 143349311 2 5 01 0 143349312 143349311
The disk described is a SAS disk, target 0 with an SMI VTOC label. The prtvtoc command shows the number of cylinders and heads, as well as how the disk’s slices are arranged.
The following is an instance of running the prtvtoc command on a SCSI disk with an EFI label:# prtvtoc /dev/rdsk/c2t1d0s1<cr> * /dev/rdsk/c2t1d0s1 partition map * * Dimensions: * 512 bytes/sector * 8385121 sectors * 8385054 accessible sectors * * Flags: * 1: unmountable * 10: read-only * * First Sector Last * Partition Tag Flags Sector signify Sector Mount Directory 0 2 01 34 41006 41039 1 2 00 41040 8327663 8368702 /mnt 8 11 00 8368703 16384 8385086 Using the format Utility to Create Slices: SPARC
Before you can create a file system on a disk, the disk must be formatted, and you must divide it into slices using the format utility. Formatting involves two divorce processes:
When a disk is formatted, header and trailer information is superimposed on the disk. When the format utility runs a surface analysis, the controller scans the disk for defects. It should be notable that defects and formatting information reduce the total disk space available for data. This is why a unusual disk usually holds only 90% to 95% of its capacity after formatting. This percentage varies according to disk geometry and decreases as the disk ages and develops more defects.
The need to perform a surface analysis on a disk drive has dropped as more manufacturers ship their disk drives formatted and partitioned. You should not need to perform a surface analysis within the format utility when adding a disk drive to an existing system unless you reflect disk defects are causing problems. The primary intuition that you would use format is if you want to view or change the partitioning scheme on a disk.
The format utility searches your system for utter attached disk drives and reports the following information about the disk drives it finds:
In addition, the format utility is used in disk repair operations to finish the following:
The installation program partitions and labels disk drives as fraction of installing the Oracle Solaris release. However, you might need to use the format utility when doing the following:
The following instance uses the format utility to create disk slices on a disk.
The system responds with the following:Searching for disks ... done AVAILABLE DISK SELECTIONS: 0. c0t0d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107> /pci@1f,0/pci@1/scsi@8/sd@0,0 1. c0t1d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107> /pci@1f,0/pci@1/scsi@8/sd@1,0

You can use the cognomen and save commands in the partition menu to cognomen and save a newly created partition table to a file that can be referenced by cognomen later, when you want to use this very partition scheme on another disk. When issuing the cognomen command, you’ll provide a unique cognomen for this partition scheme and then issue the save command to save the information to the ./format.dat file. Normally this file is located in the /etc directory, so provide the complete pathname for /etc/format.dat to update the master file.
After you partition the disk, you must label it by typing label at the partition prompt:partition> label<cr>
You are asked for confirmation on labeling the disk as follows:Ready to label disk, continue? y<cr>
Enter “Y” to continue.
After labeling the disk, nature “quit” to exit the partition menu or press Ctrl+D to exit the format utility:partition> quit<cr>
Type “quit” again to exit the format utility:format> quit<cr>
It’s vital to point out a few undesirable things that can happen when defining disk partitions with the format utility if you’re not careful. First, be watchful not to squander disk space. Wasted disk space can occur when you subside the size of one slice and finish not adjust the starting cylinder number of the adjoining disk slice.
Second, don’t overlap disk slices. Overlapping occurs when one or more cylinders are allocated to more than one disk slice. For example, increasing the size of one slice without decreasing the size of the adjoining slice will create overlapping partitions. The format utility will not caution you of wasted disk space or overlapping partitions.
The main intuition a system administrator uses the format utility is to divide a disk into disk slices. In Oracle Solaris 11 11/11, for a bootable ZFS root pool, the disks in the pool must accommodate slices and must be labeled with an SMI label. The simplest configuration would be to build the entire disk capacity in slice 0 and use that slice for the root pool. Bootable ZFS root pools are discussed further in Chapter 5.
I’ll characterize how to use the SMI label for SPARC-based systems. For example, on a SPARC-based system with a 72GB disk, you would need to own 68GB of usable space located in slice 0. Similarly, on an x86-based system with a 72GB disk, you would besides need to allow 68GB of usable space located in slice 0. A small amount of boot information is contained in slice 8. Slice 8 requires no administration and cannot be changed.
Follow these steps to partition a disk (c2t0d0) to be used as a ZFS boot disk (bootable ZFS root pool) on a SPARC-based system. If the disk has an EFI label, and the firmware has not been upgraded, you must first metamorphose it to an SMI label.
Use the prtvtoc command to verify the disk label as follows:# prtvtoc /dev/rdsk/c2t0d0s2<cr>
The system displaysPart Tag Flag Cylinders Size Blocks 0 root wm 1 - 14086 68.35GB (14086/0/0) 143339136 1 unassigned wm 0 0 (0/0/0) 0 2 backup wu 0 - 14086 68.35GB (14087/0/0) 143349312 3 unassigned wm 0 0 (0/0/0) 0 4 unassigned wm 0 0 (0/0/0) 0 5 unassigned wm 0 0 (0/0/0) 0 6 unassigned wm 0 0 (0/0/0) 0 7 unassigned wm 0 0 (0/0/0) 0
Notice that slice 2 is labeled “backup” and the slices are numbered 0-7. This is an SMI label.
The following shows the output that is displayed for a disk with an EFI label:Part Tag Flag First Sector Size terminal Sector 0 usr wm 34 68.36GB 143358320 1 unassigned wm 0 0 0 2 unassigned wm 0 0 0 3 unassigned wm 0 0 0 4 unassigned wm 0 0 0 5 unassigned wm 0 0 0 6 unassigned wm 0 0 0 7 unassigned wm 0 0 0 8 reserved wm 143358321 8.00MB 143374704
Notice there is a slice 8 and slice 2 is NOT labeled “backup.” This is an EFI label and would need to be changed. use the following steps to change the label from an EFI label to an SMI label:
As root, use the format -e command and select the disk to label as follows:# format –e<cr>

As described earlier in this chapter, Oracle Solaris on the x86 platform treats disk drives slightly differently than on the SPARC-based systems. Disks on the x86 platform must own an fdisk partition table. The x86-based systems use the fdisk partition table to identify parts of the disk reserved for different OSs and to identify the partition that the system will boot from. This boot partition is referred to as the “active disk” partition. You can allocate one fdisk partition on a disk to be used for Oracle Solaris.
On an x86-based system, once a disk drive has been physically installed and verified as working, you’ll use the format command to slice the disk, but first an fdisk partition must be created on the unusual drive. You can create this fdisk partition using the fdisk command from the command line or through the format utility. The following steps characterize how to create a fixed disk partition table on a disk using the format utility:
As root, nature “format” to salvage into the format utility.# format<cr>
The following menu appears:AVAILABLE DISK SELECTIONS: 0. c1t0d0 <FUJITSU-M1606S-512-6234 cyl 3455 alt 2 hd 6 sec 102> /pci@0,0/pci9004,8178@3/cmdk@0,0 1. c1t1d0 <IBM-DFHSS1W!e-4141 cyl 4071 alt 2 hd 4 sec 135> /pci@0,0/pci9004,8178@3/cmdk@1,0 2. c1t2d0 <DEFAULT cyl 2928 alt 2 hd 6 sec 120> /pci@0,0/pci9004,8178@3/cmdk@2,0 Specify disk (enter its number):

Select the fdisk option and the following menu appears:The recommended default partitioning for your disk is: a 100% "SOLARIS System" partition. To select this, gladden nature "y". To partition your disk differently, nature "n" and the "fdisk" program will let you select other partitions.
If you wish to use the entire drive for Oracle Solaris, enter “Y.” This will recrudesce you to the format menu. If “N” is entered, the fdisk menu will be displayed.Total disk size is 4073 cylinders Cylinder size is 540 (512 byte) blocks Cylinders Partition Status nature Start cessation Length ========= ====== ======== ===== === ====== === THERE ARE NO PARTITIONS CURRENTLY DEFINED SELECT ONE OF THE FOLLOWING: 1.

Disks on x86-based systems can be divided into 10 slices labeled slice 0 through slice 9. On Oracle Solaris 11/11, slices 0 through 7 are used for the very purposes as disk slices create on SPARC-based systems. Slice 2 represents utter of the space within the fdisk partition. As stated earlier, slices 8 and 9 are used for purposes specific to x86-based hardware. You cannot modify slices 8 and 9 using the format utility. nascence with Oracle Solaris 11.1, the boot disk on an x86-based system can accommodate an EFI label, and the partition scheme is slightly different than the SPARC system. Slice 0 is reserved for the BIOS_boot information. I’ll characterize this more in the next chapter.
Here’s an instance of the partition table on an IDE or SATA disk on an x86-based system running Oracle Solaris 11/11, as displayed by the format utility:Part Tag Flag Cylinders Size Blocks (output omitted) 8 boot wu 0 - 0 7.84MB (1/0/0) 16065 9 alternates wm 1 - 2 15.69MB (2/0/0) 32130
In the previous example, notice that slice 9 is defined and tagged as the alternates slice.
The next instance shows the partition table for a SCSI disk attached to an x86-based system. Notice that partition 8 is assigned, but slice 9 is not used:Part Tag Flag Cylinders Size Blocks (output omitted) 8 boot wu 0 - 0 7.84MB (1/0/0) 16065 9 unassigned wm 0 0 (0/0/0) 0
One more item of note: On criterion UFSs, don’t change the size of disk slices that are currently in use. When a disk with existing slices is repartitioned and relabeled, any existing data will be lost. Before repartitioning a disk, first copy utter of the data to tape or to another disk.
You can besides create the fixed disk partition table on an x86-based system disk from the command line using a single command as follows:# fdisk –B c1t0d0<cr>
The –B option creates a single fixed disk partition that spans the entire disk. The following 36GB disk was formatted using the fdisk –B command:Part Tag Flag Cylinders Size Blocks 0 unassigned wm 0 0 (0/0/0) 0 1 unassigned wm 0 0 (0/0/0) 0 2 backup wu 0 - 4695 35.97GB (4696/0/0) 75441240 3 unassigned wm 0 0 (0/0/0) 0 4 unassigned wm 0 0 (0/0/0) 0 5 unassigned wm 0 0 (0/0/0) 0 6 unassigned wm 0 0 (0/0/0) 0 7 unassigned wm 0 0 (0/0/0) 0 8 boot wu 0 - 0 7.84MB (1/0/0) 16065 9 unassigned wm 0 0 (0/0/0) 0
The fdisk –B command can besides be used to metamorphose a disk label from an EFI to SMI.
To verify that a disk contains a fixed disk partition table, issue the following command:
# fdisk -v -W - /dev/rdsk/c3t0d0p<cr>
The system displays the fdisk table for disk c3t0d0:* /dev/rdsk/c3t0d0p0 default fdisk table * Dimensions: * 512 bytes/sector * 63 sectors/track * 255 tracks/cylinder * 2088 cylinders * * systid: * 1: DOSOS12 * 2: PCIXOS * 4: DOSOS16 * 5: EXTDOS * 6: DOSBIG * 7: FDISK_IFS * 8: FDISK_AIXBOOT * 9: FDISK_AIXDATA * 10: FDISK_0S2BOOT * 11: FDISK_WINDOWS * 12: FDISK_EXT_WIN * 14: FDISK_FAT95 * 15: FDISK_EXTLBA * 18: DIAGPART * 65: FDISK_LINUX * 82: FDISK_CPM * 86: DOSDATA * 98: OTHEROS * 99: UNIXOS * 100: FDISK_NOVELL2 * 101: FDISK_NOVELL3 * 119: FDISK_QNX4 * 120: FDISK_QNX42 * 121: FDISK_QNX43 * 130: SUNIXOS * 131: FDISK_LINUXNAT * 134: FDISK_NTFSVOL1 * 135: FDISK_NTFSVOL2 * 165: FDISK_BSD * 167: FDISK_NEXTSTEP * 183: FDISK_BSDIFS * 184: FDISK_BSDISWAP * 190: X86BOOT * 191: SUNIXOS2 * 238: EFI_PMBR * 239: EFI_FS * Id Act Bhead Bsect Bcyl Ehead Esect Ecyl Rsect Numsect 191 128 0 1 1 254 63 1023 16065 33527655 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
When there are multiple disks of the very nature (manufacturer, model, size, and geometry) to be sliced, you can save time by copying the label from a source disk over to a target disk without going through utter of the steps using the format utility. use the prtvtoc command to salvage the partition table from the source disk (c0t0d0) and write the table to the target disk (c0t1d0) using the fmthard command as follows:# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard –s - /dev/rdsk/c0t1d0s2<cr>
Richard N. Gardner, who helped mold U.S. curious policy and generations of policymakers as a Columbia Law School professor for nearly six decades and as a U.S. ambassador to Italy and Spain, died Feb. 16 at his home in unusual York City. He was 91.
The intuition was congestive heart failure, said his daughter, Nina Gardner.
Gardner spent more than half a century touching between academia and government, training the legal and economic expertise that he gained as a Yale law student and Rhodes scholar on some of the most pressing global concerns of the cold War and its aftermath.
At Columbia, he was best known for his seminar "Legal Aspects of U.S. curious Economic Policy," which he taught from 1955 until his retirement in 2012. Enrollment was famously competitive, and Gardner invited those admitted to complete notecards with their contact information and career aspirations.
He called upon those notecards years later to recommend his former students for influential posts in government and beyond, pile what the Chronicle of Higher Education once described as "a global network of lawyers, diplomats, business leaders and policy makers."
Gardner held a progression of his own influential government posts nascence in the 1960s, when he served under Presidents John F. Kennedy and Lyndon B. Johnson as deputy aide secretary of condition for international organization affairs. He later served as ambassador to Italy from 1977 to 1981, under President Jimmy Carter, and as ambassador to Spain from 1993 to 1997, under President Bill Clinton.
He was a forceful proponent of international institutions including the United Nations and their role in addressing such problems as environmental degradation - an belt where he was credited with sounding a prescient alarm.
"We are finally nascence to recognize that how a nation deals with its national environment is no longer its own and nobody else's business," he wrote in a unusual York Times commentary in 1970. "We are nascence to comprehend the union of the world's ecological system, which means that utter nations may be affected by how any one of them treats its air, water and land."
He faced perhaps his most challenging government assignment as ambassador to Italy, at a time when the Communist Party seemed ascendant and when the country was in the throes of the violence sponsored by the leftist Red Brigades.
In the past, the United States had sought to influence Italian elections through CIA activity, according to journalist Tim Weiner's bespeak "Legacy of Ashes: The History of the CIA." Gardner said that as ambassador he vowed to veneration Carter's inaugural vow that "we will not behave in curious places so as to violate their rules and standards here at home."
"I took that very seriously," Gardner recalled in remarks before the Council on curious Relations in 2005. "I said, they are going to combat the communists, but using public diplomacy. . . . There are going to be no dirty tricks."
He invited to the U.S. Embassy Italian cultural figures including filmmaker Federico Fellini and writers Leonardo Sciascia and Alberto Moravia, who he said had been previously omitted from official guest lists because of their leftists politics. The Times described him as the "first American ambassador to Italy to gain formal approaches to the Communist Party."
Writing in the Times in 1983, he recalled engaging in "much table pounding in Washington" to obtain funds to train Italian teachers of English and English-speaking teachers of Italian.
He besides sought to enlarge the number of American texts available to Italian readers, noting ruefully that when he requested an Italian translation of the Federalist Papers, he scholarly they had been out of print in Italian for years. The works of Marx , Lenin and Stalin, however, were widely available.
He was credited with helping prevail Italy to become the first European country to accept U.S. cruise missiles on its land, an vital achievement at the time. But "we appear to own forgotten the obvious verity that you don't defend national security with arms alone," he wrote in the Times commentary. "The Soviet SS-20 missile is a threat to European security, but just as mighty a threat is the leisurely and equable erosion of common values and interests that is the foundation of the Atlantic alliance."
Richard Newton Gardner was born in unusual York City on July 9, 1927. His father was a lawyer, and his mother was a homemaker.
After stateside Army service during World War II, Gardner received a bachelor's degree in economics from Harvard University in 1948. He was a 1951 graduate of Yale Law School and received a PhD in economics from the University of Oxford in 1954.
His books included "Sterling-Dollar Diplomacy: The Origins and the Prospects of Their International Economic Order" (1956), "In Pursuit of World Order: U.S. curious Policy and International Organizations" (1964), and a memoir, "Mission Italy: On the Front Lines of the cold War" (2005).
Gardner advised two Democratic presidential candidates, Clinton in 1992 and Al Gore in 1998, on curious policy during their White House campaigns. As ambassador to Spain during the Clinton administration, he sought to defend intellectual property rights for U.S. software makers and to boost sales of U.S. helicopters.
His wife of 51 years, the former Danielle Luzzatto, died in 2008. Survivors comprise two children, Nina Gardner of Washington and Anthony Gardner, who served under President Barack Obama as U.S. ambassador to the European Union, of London; and three grandchildren.
His wife, whose family, dote Gardner's, was of Jewish heritage, was born in Italy and fled to the United States after the promulgation of the 1938 anti-Semitic racial laws under fascist dictator Benito Mussolini.
Gardner credited her as a co-ambassador, especially during their time in Italy. She once came home from the hairdresser and reported that she had heard from the mistress of "Minister X" that the minister was going to resign - "and it was an vital minister," Gardner joked before the Council on curious Relations.
He informed his colleagues in the CIA, who did not believe the report, until the minister stepped down that Friday. The following Monday, his colleagues demanded to know where he had gotten his tip. "I took mighty joy," he recalled, "in aphorism to the CIA, 'I never disclose sources.' "

The unusual York City Housing Authority, amenable for 176,000 apartments in 2,418 buildings, is by far the biggest public-housing system in the country. Beset by lead-paint hazards, mold, heating failures and habitual mismanagement, NYCHA buildings are besides a danger to the authority’s 400,000 residents — the population of a mid-size American city.
On Jan. 31, unusual York narrowly avoided a complete federal takeover of NYCHA by agreeing to disburse $2.2 billion on a decade-long effort to repair NYCHA’s decrepit buildings and by ceding much management responsibility to a powerful federal monitor. Housing and Urban evolution Secretary Ben Carson and Mayor Bill de Blasio (D) announced the agreement at HUD’s Lower Manhattan offices on the deadline date set by a federal judge who terminal drop had rejected an earlier agreement as inadequate.
The unusual agreement is besides inadequate. That was made limpid Monday with news that interim NYCHA chairman Stanley Brezenoff refused to token the agreement. The deal unfairly places “all of the pecuniary burden” on the city and not on the federal government, where it belongs, he told the unusual York Times. The city had announced terminal week that he was being replaced.
Last summer, NYCHA estimated that $32 billion would be needed over five years to fix its buildings, which are on middling more than 60 years old, according to the unusual York Times. The city could never afford to disburse that much on these essential repairs. Federal funding will be required if the public-health juncture is going to be effectively addressed and HUD is going to fulfill its duty to provide safe and decent housing. HUD provides $2 billion of NYCHA’s $3.2 billion annual operating budget.
The conditions of public housing in unusual York City are deplorable. More than 59 percent of NYCHA residents surveyed reported mold in their units, and 52 percent reported leaking roofs, windows or plumbing. More than 800 children under age 6 and animate in NYCHA housing tested positive for tall levels of lead between 2012 and 2016. The housing authority had ignored lead-paint safety regulations for years.
The alarming deterioration of unusual York’s public housing occurred in tandem with equable federal funding cuts to public housing nationwide, reductions that picked up hasten under the Trump administration. According to the Wall Street Journal, the administration made an initial cleave of at least $35 million for 2017 as fraction of an expected $150 million total.
When billions are needed but millions are being cut, the authorization of a federal monitor is the equivalent of nailing a 2-by-4 to a collapsing building.
NYCHA’s neglect has had staggering consequences for children’s health. Lead poisoning can result in reduced IQ, developmental delays, academic failure, juvenile delinquency, behavioral problems, biological and neurological damage and premature death. The Centers for Disease Control and Prevention makes it clear: “There is no known safe smooth of lead.” A unusual York condition report terminal year create that 80 percent of NYCHA buildings, where mold is rife, had conditions that could contribute to asthma in children. As the CDC notes, asthma is a leading intuition of school absences and reduced daily activities; in 2008 alone, asthma caused 14.2 million missed days of travail and 10.5 million missed days of school nationwide, affecting children from low-income families at the highest rates.
Yet NYCHA does not own the funds necessary to address the more than 245,000 open travail orders for repairs, let lonesome employ enough lead-hazard risk investigators or mold remediation specialists to address these problems.
Shockingly, the unusual NYCHA agreement with HUD provides no supplemental federal funding for mold and lead-hazard inspection and remediation. Instead, the agreement mandates the use of “visual assessments” for lead hazards. As The Post reported in a tragic 2017 tale about lead hazards in D.C. public housing, one of the “key weaknesses of federal guidelines” mandated by HUD and followed by the District is that inspectors depend on visual inspections for peeling paint and deteriorating conditions “instead of specifically testing for lead or asthma-inducing mold.” In effect, children in federally assisted housing must develop lead poisoning before meaningful inspections occur.
HUD’s want of oversight, compliance review and long-term planning is a problem that reaches far beyond NYCHA. June 2018 reports from HUD’s Inspector universal and the Government Accountability Office on the conditions of federally assisted housing create wide margins for fraudulent reporting. For example, the East Chicago Housing Authority in Indiana was allowed to falsely self-certify compliance as generations of families were exposed to lead and arsenic while residing in public housing on a Superfund site.
HUD’s perfunctory approach to its responsibilities, combined with inadequate federal funding, has resulted in squalid environments that menace the health and livelihoods of public-housing residents. By disinvesting in housing for low-income families, Congress and HUD are thwarting progress, perpetuating racial segregation and increasing the cycle of poverty for future generations. The federal government has an obligation to protect those who qualify for federal assistance. If generations of children are going to thrive, they first must live in homes and communities that government neglect and indifference haven’t made Dangerous to their health.
