Peter Gregory discusses user account configuration information; including, modifying, and deleting person money owed with Admintool and shell commands; consumer shells; and user account commands in Solaris 8.
This pattern chapter is excerpted from sun licensed system Administrator for Solaris eight analyze guide, via Peter Gregory.This chapter is from the ebook
After completing this chapter, you'll be capable of
establish here login procedures: log right into a equipment, log out of a gadget, and change login passwords.
State the command used to establish which clients are presently logged into the equipment.
State the steps required to create person bills on the local equipment the use of the admintool utility.
State the command syntax to add, modify, or delete person/community bills on the native gadget with the useradd, groupadd, usermod, groupmod, userdel, or groupdel instructions.
Given a user's login shell, listing the shell initialization files used to installation a consumer's work environment at login.
to fulfill these pursuits, this chapter discusses:
consumer account configuration files;
adding, editing, and deleting user accounts with Admintool;
adding, enhancing, and deleting consumer bills with shell instructions;
person shells; and
user account commands.
Three essential files outline the identity of a user account: the password file, the shadow file, and the group file.The Password File
The password file consists of the primary settling on tips for every person allowed to access a gadget. The system vicinity of the password file is /and many others/passwd. The structure of the password file is:username:password:uid:gid:gcos-field:home-dir:login-shell
These fields are:
username—the name that identifies the person account.
password—in Solaris 8 an "x" during this box implies that the corresponding shadow file incorporates the encrypted password string.
uid—the pleasing numerical identity assigned to the account. The maximum cost for UID is 2147483647, however directors are urged to make use of values lower than 60,000 to make sure compatibility with all the equipment which are used to manipulate debts or screen guidance that comprises usernames.
gid—the fundamental (default) numerical neighborhood identification assigned to the account. like the UID field, the maximum cost for GID is 2147483647, but a maximum of 60,000 is preferable.
gcos-box—this is the user's real name (the time period "gcos-box" is the historical term for this container).
domestic-dir—the directory the place the person is positioned after logging in; this usually includes the person's own info and directories.
login-shell—the initial shell that is begun on behalf of the user upon logging in. If this container is blank, then /usr/bin/sh is used.
The password file can also be read through any person on the system. There isn't any information that must be saved secret during this file. A pattern password file looks like this:root:x:0:1:super-consumer:/:/sbin/sh daemon:x:1:1::/: bin:x:2:2::/usr/bin: sys:x:3:three::/: adm:x:four:four: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 pay attention:x:37:four:community Admin:/usr/internet/nls: pete:x:one hundred:four:Peter Gregory:/export/domestic/pete:/bin/sh no person:x:60001:60001:no one:/:
Fields in the password file are delimited by colons (":"), and blank fields are signified by using two adjoining colons ("::"). for example, observe that the account identify field for daemon is clean—just two colons. additionally, daemon has no shell entry, so the ultimate character for daemon is the colon delimiter.
The colon delimiter is additionally used in the shadow and neighborhood information, which might be mentioned in a later area.
it's feasible and permissible to create more than one username within the password file with the equal UID. each and every username may have its personal entertaining password. despite the fact, tools comparable to ls and ps, when used with alternate options exhibiting username, will reveal the primary username found in the password file matching the UID.
When a new account is added, modified, or removed with the useradd, usermod, or userdel commands (that are discussed later during this chapter), the gadget creates a backup copy of the password file, called /and many others/opasswd.The Shadow File
The shadow file carries each and every user account's encrypted password, in addition to certain per-account parameters governing "password getting older." The gadget region of the shadow file is /etc/shadow. The layout of the shadow file is:username:password:lastchg:min:max:warn:inactive:expire:flag
These fields are:
username—here is the same username present in the password file.
password—a 13-character encrypted password. If this field carries a lock string (e.g., "locked" or "NP"), the account is inaccessible; if blank, the account has no password.
lastchg—date of ultimate password change (actually the number of days between January 1, 1970, and the date the password turned into closing modified).
min—minimum variety of days allowed earlier than the password may also be changed.
max—optimum number of days allowed before the password expires.
warn—the variety of days ahead of expiration that the user is warned.
inactive—the number of days of state of no activity allowed for the account earlier than the account is instantly locked.
expire—the date when the consumer account is deactivated.
flag—a box reserved for future use.
The shadow file is restricted so that most effective the system administrator can read it. here's because an outsider might operate a "dictionary attack," the use of guessable passwords in an attempt to examine the passwords for one or greater money owed. classes that "crack" account passwords can be found for this intention; as a result, the shadow file is not publicly readable.
A sample shadow file seems like 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:::::: no one:NP:6445::::::
note that one of the debts within the illustration shadow file have "NP" ("no password") or "*LK*" (locked) in them. These are only two approaches of signifying that the bills are locked in opposition t login. there is nothing definitely magic about "NP" or "*LK*"—they are only a method of simply showing that these money owed are locked and going to dwell that means. You might put different textual content in the password container to fit your wants; as an example, a helpdesk ticket quantity or a date.
When a person alterations his or her password, the system creates a backup reproduction of the shadow file, known as /and so on/oshadow. This also happens if root adjustments a consumer's password.
suppose About It . . .
Why are encrypted passwords present in /and so forth/shadow and never in /and so forth/passwd?
for many instructions (ps, ls, and many others.) to work adequately, /and many others/passwd have to be world readable. in advance of using /and so on/shadow, all users' encrypted password strings have been additionally publicly readable. This gave individuals with "password cracking" courses an opportunity to find different clients' passwords. by means of moving the encrypted password strings to /and so on/shadow (which will also be study simplest by means of root), the potential to entry encrypted passwords is eliminated.
First, slightly of background. Older types of UNIX did not have a shadow file; instead, the encrypted password string turned into present in the password file, within the 2nd container it truly is constantly filled with an "x" in Solaris. Solaris nonetheless supports the encrypted password acting in the password file, however this is no longer a good idea, since the password file is publicly readable.
Older versions of UNIX with no shadow file additionally had no password-getting old capability.
The network advice equipment (NIS) subsystem turned into designed across the historic shadow-less structure; this explains why NIS has no shadow map, nor does it assist password getting older.The group File
The group file includes a list of the entire corporations on the equipment, along with each and every group's numeric groupid and a listing of every of the usernames that are secondary members of each and every community. The region of the community file is /etc/community. The format of the group file is:groupname:password:gid:consumer-listing
These fields are:
groupname—here's the name of the community.
password—here is an optional password for the neighborhood.
gid—the enjoyable numerical identification assigned to the community. The highest price for GID is 2147483647, however directors are entreated to make use of values lower than 60,000 to make sure compatibility with all of the tools which are used to manage accounts or monitor information that includes community names.
user-checklist—a comma-separated list of clients allowed in the group. These organizations are clients' secondary community IDs.
A sample community 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 group of workers:GSSUYVrJ8EKyA:10:pete daemon::12:root,daemon sysadmin::14: no one::60001: noaccess::60002: nogroup::65534:
notice the password container within the community "personnel." businesses can be password protected by using placing a password string into the password field. note, even though, that here is a very manual manner; there are not any tools provided to put the group password in for you.
hint: you could take a password string from the shadow file and use the vi editor to splice it into the neighborhood file. The community password may be the equal because the account password from the shadow entry the place you took the password string.
When a bunch is password included, any one who is not a member of the neighborhood could be challenged for the community's password when they've entered the newgrp command.simple and Secondary Groupids
each and every person account has one primary groupid—here is the community defined in the password file. When a person logs on, here is his or her associated groupid.
each user account also has zero or extra secondary groupids. A person's secondary companies are these community entries that consist of the username in their lists of members.
There are some valuable obstacles of groupids. as an example, each person account can also be in no more than sixteen agencies, and a line within the neighborhood file can't exceed 512 characters (together with the newline character).
What happens if you should add so many contributors to a group that you exceed the 512-persona entry restrict? You comfortably create an extra duplicate neighborhood entry—equal identify and community number—and listing the further individuals there.
The primary and secondary groupids at once influence file system access permissions, which is explored wholly in Chapter 10.
think About It . . .
What may be the effect if a username have been brought to a bunch file entry when that community turned into the user's primary group?
The extra entry would haven't any effect, due to the fact that the user is already configured for the fundamental neighborhood membership in the /and many others/passwd file.the foundation Account
the root account has particular privileges on a device: Root is accepted to read and write each file on a system, inspite of the file's ownership and permission settings. equipment directors log in with the root account so that you can operate administrative initiatives.
the root account receives its power and privilege from the cost of its consumer quantity: Root is user number zero, defined in the password file.
suppose About It . . .
What stands out as the consequences of changing a normal consumer's user number to zero? What talents may there be of placing root's entry on the end of the passwd file (instead of the starting)?
changing a regular user's person number to zero offers the user root privileges.
One potential of inserting root on the conclusion of the password file is that if an intruder is capable of adjust the password file to supply one more consumer root privilege (see the first query here), then output from commands reminiscent of ls and ps would display that different consumer as the owner of root tactics and data.

AS-1 was synthesized as described previously18. AS-1 was obtained as pale yellowish oil and dried in vacuo for 24 hours. The structure of AS-1 was examined by nuclear magnetic resonance (1 H NMR): (500 MHz, MeOD): 7.34–7.17(m, 5 H), 6.24 (d, J = 8.4 Hz, 1 H), 4.60, 4.58 (dd, J = 6.8 Hz, 7.2 Hz, 1 H) 3.74–3.70(m, 1 H), 3.49–3.40(m, 3 H), 2.99–2.92(m, 3 H), 2.53(t, J = 8.0 Hz, 1 H), 1.97–1.83(m, 5 H), 0.90 (d, J = 6.8 Hz, 3 H), 0.82 (d, J = 6.8 Hz, 3 H); LRMS (EI, 70 eV) m/z(%): 302 (M + 5), 260(2), 204(14), 154(5), 127(4), 105(8), 91 (14), 72(100). The crystals of AS-1 were dissolved and prepared in DMSO. No significant-cytotoxicity of AS-1 was observed by cell viability (MTT) assay (data not shown).Experimental mice
Male C57BL/6 mice, 6–8 weeks, weighted 18–22 g, were provided by the Laboratory Animal Research Center of Jiangsu University (Zhenjiang, China). 3–5 mice/cage were bred and kept under defined-flora, pathogen-free conditions in the animal research center under an artificial 12/12 light-dark cycle and with room temperature of 18 °C to 23 °C. Mice were allowed free access to regular food and water. Animal experiments were approved by the animal ethics committee of the Jiangsu University. Study methods were carried out in accordance with relevant guidelines and regulations.Mouse model of Ang II-induced cardiac hypertrophy
The continuous infusion of Ang II was achieved by using an indwelling, chronically implanted osmotic mini-pump (model 2004, ALZET Technical Services, USA) as previously described36. Specifically, the mini-pump was subcutaneously embedded in mice under anesthesia condition (80 mg/kg ketamine and 8 mg/kg xylazine). Ang II (1 μg/kg/min) or normal saline was infused constantly for four weeks. 3 days before implantation of osmotic mini-pump, mice were intraperitoneally injected with AS-1 (50 mg/kg/day) for 4 weeks. AS-1 was prepared by mixing one volume of AS-1 in DMSO with three volumes of saline to give a final concentration of 50 mg/kg body weight. Vehicle control was prepared by mixing one volume of DMSO with three volumes of saline. Four weeks after Ang II infusion, hearts were harvested and the ratio of heart weight/body weight (HW/BW) and left ventricular weight/tibia length (LVW/TL) were calculated. The harvested heart samples were processed for further analysis. Experimental mice were assigned to four groups according to different treatments: sham control (sham), Ang II-induced (Ang II), Ang II-induced + DMSO, Ang II-induced + AS-1.Echocardiography and tail cuff blood pressure measurement
Cardiac functions were evaluated by echocardiography using a 40 MHz transducer and a VEVO 2100 console (VisualSonics, Toronto, ON, Canada). Echocardiography was obtained on anesthetized mice 4 weeks after implantation of osmotic mini-pump. M-mode tracings were used to measure intraventricular septum thickness in diastole (IVS, d) and thickness of the rear wall of the left ventricular (LVPW, d). Echocardiography was done by an experienced echocardiographer in a double-blind manner. All measurements were averaged over six consecutive cardiac cycles. Mouse blood pressure was determined by the measurement of tail cuff blood pressure and averaged over three measurements.Cell culture
Primary cultures of cardiomyocytes were isolated from 1 to 3-day-old neonatal rats as described previously18. Briefly, after sacrificing, the hearts of newborns were removed under sterile condition. Ventricular tissues were excised, minced and digested with 0.08% trypsin (Gibco, USA). Cells were centrifuged at 1,800 rpm/min for 5 min and resuspended in Dulbecco’s Modified Eagle’s Medium (DMEM) (Gibco, USA) supplemented with penicillin/streptomycin (Beyotime Biotechnology, China) and 10% fetal bovine serum (FBS) (Gibco, USA). Primary cells were induced with Ang II (0.1 μM) for 24 hours. AS-1 (100 μM) or DMSO was administrated 30 min before Ang II application.Synthesis and administration of antagomirR-143
The micrOFFTM mmu-miR-143-3p antagomirR (antagomiR-143) and scramble siRNA were purchased and synthesized by RiboBio (Guangzhou, China).Overexpression of miRNA-143
Control miRNA and miRNA-143 mimics were synthesized and obtained from Guangzhou RiboBio (Guangzhou, China). The miRNA was transfected into the primary cardiomyocytes using Lipofectamine 3000 (Invitrogen, USA) according to the manufacturer’s instructions. The sequences used in this study are as follows: miRNA control, 5′-UCACAACCUCCUAGAAAGAGUAGA-3′; rno-miR-143-3p mimics, 5′-UGAGAUGAAGCACUGUAGCUCAUGAGCUACAGUGCUUCAUCUCA-3′.Quantitative real-time PCR (qRT-PCR)
RNA levels were measured by qRT-PCR. Briefly, RNAs of primary cardiomyocytes were extracted using RNAiso reagent (Takara Biotechnology). Subsequently, total RNA was reverse transcribed to complementary DNA (cDNA) according to the protocol of PrimeScriptTM RT detection kit (for mRNA) or PrimeScriptTM miRNA RT detection kit (for miRNA) (Takara Biotechnology). The RT primer of miRNA-143: 5′ GTCGTATCCAGTGCGTGTCGTGGAGTCGGCAATTGCACTGGATACGACTGAGCT 3′; RT primer of U6: 5′ CGCTTCACGAATTTGCGTGTCAT 3′. qPCR Primer sets are indicated in Table 1. All primers were synthesized by Sangon Biotech (Shanghai, China). qPCR reactions were performed using the SYBR Premix Ex TaqTM II kit as described by the protocol. The same thermocycling profile was used for all genes: 95 °C for 10 minutes, followed by 40 cycles of 95 °C for 15 seconds, 58 °C for 30 seconds, and 72 °C for 20 seconds.Immunofluorescence staining
Cells were rinsed three times in pre-cold PBS, followed by fixation using 4% paraformaldehyde (PFA)/phosphate-buffered saline (PBS) for 20 minutes at room temperature. Cells were permeabilized by 0.1% Triton X-100 for 20 minutes followed by blocking with 3% bovine serum albumin (BSA) for 30 minutes at room temperature. Then, cells were incubated at 4 °C overnight with anti-α-actinin (Sigma) or p50 NF-κB (CST) primary antibody. The Alexa Fluor 488-conjugated secondary antibody (1:500) was used to visualize α-actinin. The Alexa Fluor 594-conjugated secondary antibody (1:500) was used to visualize p50. The images were taken under a fluorescence microscope (Olympus). Confocal images were acquired with a laser-scanning confocal microscope (Zeiss LSM 510 META).Wheat germ agglutinin (WAG) staining
The saline-perfused mouse hearts were fixed in 4% PFA and embedded for paraffin blocks. Paraffin sections were prepared according to published protocols. To visualize cellular borders, dewaxed paraffin sections were incubated with WAG working buffer (5 μg/ml) for 1 hour. After rinse with PBS for three times, sections were mounted with a drop of mounting medium. Images were taken under a fluorescence microscope (Olympus).Western blot
Primary cardiomyocytes were lysed with ice-cold RIPA lysis buffer. Western blot was performed as described elsewhere17. Briefly, proteins were separated by SDS-PAGE and transferred onto polyvinylidene difluoride (PVDF) membranes (Amersham Biosciences, USA). The PVDF membranes were incubated with anti-ERK1/2 and anti-phospho-ERK1/2 antibodies (Cell Signaling Technology, USA), followed by incubation with peroxidase-conjugated secondary antibody. The signals were detected with the ECL system (Pierce, USA). Qualification of signals were performed by ImageJ software.Statistics
