Open-source storage explained | killexams.com actual questions and Pass4sure dumps

Open-source storage software is freely available, but it's the rare IT department that's willing to cobble it together with hardware to build a storage system.

Corporations are more likely to expend it by happenstance, acquiring it through storage systems they buy from major vendors, some of which embed open-source technology into their products.

Other companies are game to try software applications served up with advocate contracts from a scattering of minuscule vendors, such as Zmanda Inc. and Bacula Systems SA in the backup space. And the truly industrious might ferret out nascent open-source storage projects on SourceForge.net.

Still, enterprise IT organizations are typically so worried about data loss that they minister to favor storage products from established vendors. That's why Sun Microsystems Inc.'s fresh  Sun Storage 7000 Unified Storage Systems, billed as "open storage appliances" and formerly known by the denomination Amber Road, beget created a stir in the market.

Launched in November, Sun's 7000 family of storage products is based on industry-standard hardware and a software stack that includes a substantial amount of open-source technology.

Sun's open-source software

The Sun stack includes the OpenSolaris operating system, with its default ZFS file system featuring simple administration, end-to-end data integrity and scalability. OpenSolaris supports not only NFS but CIFS, through an in-kernel implementation, to enable file access with Windows-based systems. Users who prefer Samba for file-and-print services to CIFS clients can expend that open-source technology.

"In terms of vendors of note, Sun is the only one that's really promoting the open-source storage approach," says Roger Cox, a research vice president in Gartner Research. "What they're trying to execute is derive various development communities to capture their software, Solaris/ZFS, and add some modifications to it, add some value to it and create storage solutions based on that technology, which then allows Sun to design money based on maintenance."

Two vendors -- greenBytes Inc. and Nexenta Systems Inc. -- beget already picked up the torch and built storage systems based on Solaris and ZFS. But it's too early to expose if Sun will live able to capitalize on the model that made Linux grow in popularity.

"It does beget promise," says Cox, "in the sense that this can beget a major repercussion in terms of reducing costs for storage, particularly in today's economic environment with people not having the benign of money they've had in the past. Storage data doesn't halt growing, and they beget to supersede products that beget reached their [end of] lifecycle."

What caught the attention of Gene Ruth, a senior storage analyst at Midvale, Utah-based Burton Group, is the course the ZFS file system has been adjusted to leverage the capability of solid-state disk (SSD). "They're one of the first to present solid-state disks that are uniquely integrated into the storage system," says Ruth.

ZFS automatically writes fresh data to the write cache located on an SSD and determines data access patterns and stores frequently accessed data on an SSD, according to Sun.

John Webster, principal analyst at Nashua, N.H.-based Illuminata Inc., says the reseller community isn't typically attracted to Sun storage, yet it appears to fancy the fresh open technology. If interest in Sun's fresh systems grows, that moreover might spark more interest in open-source storage technology in general, as the storage world continues toward commoditization.

"There's significant momentum developing behind this open-source storage movement. I don't know how far it's going to go. Certainly, there are going to live some resisters, and certainly the IT community isn't going to buy off on this concept overnight," says Webster. "But I deem it's going to grow in magnitude and will become a significant threat to the more proprietary forms of storage that they now see. The IT community will always live attracted to functionality at a lower cost."

User challenges

However, users might not want to live the ones structure the systems. Those who execute often find they necessity to expend increasing levels of ail to tune and maintain them, especially if the systems are heavily customized.

Chelmsford, Mass.-based OurStage Inc., a Web site catering to fresh music, noticed gradual storage performance six months after putting together a mixed NAS and iSCSI system using CentOS Linux, which is based on code from Red Hat Inc., running on white-box hardware from Tyan Computer Corp. and Super Micro Computer Inc. Ultimately, the tech team hit a wall in its comprehension of the causes and its attempts to tune around them.

"The farther you go, you beget to set more and more labor in to derive less and less gain," says stamp Niedzielski, infrastructure manager at the Web startup. OurStage, which joined Sun's Startup Essentials program, now runs OpenSolaris on three white boxes and one of Sun's Storage 7210 Unified Storage boxes.

Red Hat's storage capabilities

Sun isn't the only one claiming its operating system is conducive to storage. Red Hat says its  Red Hat Enterprise Linux Advanced Platform (RHEL-AP) offers significant storage capabilities, which are embedded in storage hardware or available as layered software products.

For instance, RHEL-AP's clustered file system -- Global File System (GFS) -- provides cluster-wide, fully synchronized, parallel read/write access to shared storage, according to Nick Carr, Red Hat's marketing director.

RHEL-AP moreover includes a ratiocinative volume manager (LVM) to manage a large, disparate physical storage configuration as a sole ratiocinative entity. Other capabilities include advocate for standard RAID levels, cloning, multiple read/write snapshots and multipathing.

Linux can moreover live used as a server with advocate for CIFS, NFS and iSCSI block clients, as well as advocate for Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), iSCSI (host and target), and 10 GB Ethernet, according to Carr.

Users beget the option of structure their own systems or deploying a pre-built, tested, certified and supported package through a Red Hat subscription.

Open-source backup

Open-source storage doesn't halt at the operating and file systems. Zmanda, for example, espouses the Red Hat model and offers a freely downloadable community edition of its  Amanda network backup software, as well as an enterprise edition that it has sold as an annual subscription since 2007.

Zmanda CEO and founder Chander Kant says the software, which is based on an open-source project at the University of Maryland, has attracted a following at universities, small- and medium-sized businesses (SMBs), and even departments at some Fortune 1000 companies. Zmanda, which launched in 2005, finished ahead of draw in the final quarter of ultimate year despite the failing economy, according to Kant.

"In general, what they find in these economic times is that bells and whistles aren't so notable for administrators. But they execute want a backup solution," says Kant.

Chris Hoogendyk, systems administrator for the biology and geology departments at the University of Massachusetts in Amherst, says the main driver for open-source storage was the cost-benefit analysis. He says he typically has to wait for a department to budget for tape libraries.

"Open source doesn't cost you an arm and a leg and, in this case, it's ripen enough that it has everything you need," says Hoogendyk, who's been accountable for backup on network systems since 1992. "In addition, there's a whole issue that you've got an open and fairly great community of people who capitalize each other and provide information and contribute to the development. And if you beget any questions about how it works, you can actually open it up and study at the code."

Hoogendyk has been using the community edition of Zmanda for approximately two years and now does part-time consulting on behalf of Zmanda, providing advocate on its online forums.

Kant says the biggest reason customers turn to Zmanda, other than cost, is its advocate of open and standard formats for storing data -- tar for Linux and Unix, and ZIP for Windows. He adds that Zmanda moreover uses industry-standard compression and encryption algorithms.

"Systems administrators can retrieve their data with standard operating system utilities, even if their software isn't around," says Kant.

Zmanda's software runs on Linux or Solaris servers, and an agent runs on every system that a user wants to use. The product will expend the backup media of the customer's choice, whether tape, disk array or the storage cloud, including Amazon's Simple Storage Service (S3), says Kant.

"Backup is considered a ripen market, but as tapes Come out of favor and technologies fancy backup to disk and the storage cloud become more popular, that creates a huge break for vendors fancy us," adds Kant.

Backup software isn't the only locality that open source has touched in storage. Sun, for instance, moreover has an open-source Storage Archive Manager that's tightly integrated with its high-performance, 64-bit Solaris SAN-based Quick File System (QFS) file system, which is moreover open source. Sun moreover maintains and supports the Lustre clustered file system.

Among the other open-source offerings are  FreeNAS software, which includes advocate for CIFS, NFS, iSCSI and software RAID; and Self-Monitoring, Analysis and Reporting Technology System (SMART) tools.

"For this year, there'll live a lot of talk and awareness centered around the value proposition of using open source to avoid costs. However, there needs to live better articulation of the total cost of ownership, [intellectual property] ownership and transfer," says Greg Schulz, founder and senior analyst at StorageIO Group in Stillwater, Minn. "Five years out, they should certainly survey more uptake in open-source solutions in generic and particularly where open-source technologies are integrated or portion of commercial packaged solutions."


Solaris 8 User Administration Tools | killexams.com actual questions and Pass4sure dumps

Peter Gregory discusses user account configuration files; adding, modifying, and deleting user accounts with Admintool and shell commands; user shells; and user account commands in Solaris 8.

This sample chapter is excerpted from Sun Certified System Administrator for Solaris 8 Study Guide, by Peter Gregory.

This chapter is from the bespeak 

After completing this chapter, you'll live able to

  • Identify the following login procedures: log into a system, log out of a system, and change login passwords.

  • State the command used to identify which users are currently logged into the system.

  • State the steps required to create user accounts on the local system using the admintool utility.

  • State the command syntax to add, modify, or delete user/group accounts on the local system with the useradd, groupadd, usermod, groupmod, userdel, or groupdel commands.

  • To fulfill these objectives, this chapter discusses:

  • User account configuration files;

  • Adding, modifying, and deleting user accounts with Admintool;

  • Adding, modifying, and deleting user accounts with shell commands;

  • User shells; and

  • User account commands.

  • Three principal files define the identity of a user account: the password file, the shadow file, and the group file.

    The Password File

    The password file contains the basic identifying information for each user allowed to access a system. The system location of the password file is /etc/passwd. The format of the password file is:

    username:password:uid:gid:gcos-field:home-dir:login-shell

    These fields are:

  • username—the denomination that identifies the user account.

  • password—in Solaris 8 an "x" in this province signifies that the corresponding shadow file contains the encrypted password string.

  • uid—the unique numerical ID assigned to the account. The maximum value for UID is 2147483647, but administrators are urged to expend values less than 60,000 to ensure compatibility with entire of the tools that are used to manage accounts or display information that includes usernames.

  • gid—the primary (default) numerical group ID assigned to the account. fancy the UID field, the maximum value for GID is 2147483647, but a maximum of 60,000 is preferable.

  • gcos-field—this is the user's actual denomination (the term "gcos-field" is the historical term for this field).

  • home-dir—the directory where the user is placed after logging in; this usually contains the user's own files and directories.

  • login-shell—the initial shell that is started on behalf of the user upon logging in. If this province is blank, then /usr/bin/sh is used.

  • The password file can live read by anyone on the system. There is no information that must live kept covert in this file. A sample password file looks fancy this:

    root:x:0:1:Super-User:/:/sbin/sh daemon:x:1:1::/: bin:x:2:2::/usr/bin: sys:x:3:3::/: adm:x:4:4:Admin:/var/adm: lp:x:71:8: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:37:4:Network Admin:/usr/net/nls: pete:x:100:4:Peter Gregory:/export/home/pete:/bin/sh nobody:x:60001:60001:Nobody:/:

    Fields in the password file are delimited by colons (":"), and blank fields are signified by two adjacent colons ("::"). For instance, note that the account denomination province for daemon is blank—just two colons. Also, daemon has no shell entry, so the ultimate character for daemon is the colon delimiter.

    The colon delimiter is moreover used in the shadow and group files, which are discussed in a later section.

    It is possible and permissible to create more than one username in the password file with the very UID. Each username will beget its own unique password. However, tools such as ls and ps, when used with options displaying username, will display the first username found in the password file matching the UID.

    When a fresh account is added, changed, or removed with the useradd, usermod, or userdel commands (which are discussed later in this chapter), the system creates a backup copy of the password file, called /etc/opasswd.

    The Shadow File

    The shadow file contains each user account's encrypted password, as well as specific per-account parameters governing "password aging." The system 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—this is the very username found in the password file.

  • password—a 13-character encrypted password. If this province contains 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 (literally the number of days between January 1, 1970, and the date the password was ultimate changed).

  • min—minimum number of days allowed before the password can live changed.

  • max—maximum number of days allowed before the password expires.

  • warn—the number of days prior to expiration that the user is warned.

  • inactive—the number of days of inactivity allowed for the account before the account is automatically locked.

  • expire—the date when the user account is deactivated.

  • flag—a province reserved for future use.

  • The shadow file is restricted so that only the system administrator can read it. This is because an intruder could achieve a "dictionary attack," using guessable passwords in an attempt to determine the passwords for one or more accounts. Programs that "crack" account passwords are available for this purpose; thus, the shadow file is not publicly readable.

    A sample shadow file looks fancy 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:::::: listen:*LK*::::::: pete:GSSUYVrJ8EKyA:11055:::::: nobody:NP:6445::::::

    Note that some of the accounts in the case shadow file beget "NP" ("no password") or "*LK*" (locked) in them. These are just two ways of signifying that the accounts are locked against login. There is nothing really magic about "NP" or "*LK*"—they are just one course of easily showing that these accounts are locked and going to stay that way. You could set other text in the password province to suit your needs; for instance, a helpdesk ticket number or a date.

    When a user changes his or her password, the system creates a backup copy of the shadow file, called /etc/oshadow. This moreover occurs if root changes a user's password.

    Exam Notes

    Think About It . . .

    Why are encrypted passwords found in /etc/shadow and not in /etc/passwd?

    For many commands (ps, ls, etc.) to labor properly, /etc/passwd must live world readable. Prior to the expend of /etc/shadow, entire users' encrypted password strings were moreover publicly readable. This gave people with "password cracking" programs an break to determine other users' passwords. By touching the encrypted password strings to /etc/shadow (which can live read only by root), the skill to access encrypted passwords is eliminated.

    First, a bit of history. Older versions of UNIX did not beget a shadow file; instead, the encrypted password string was found in the password file, in the second province that is usually filled with an "x" in Solaris. Solaris still supports the encrypted password appearing in the password file, although this is not advisable, since the password file is publicly readable.

    Older versions of UNIX with no shadow file moreover had no password-aging capability.

    The Network Information System (NIS) subsystem was designed around the primitive shadow-less architecture; this explains why NIS has no shadow map, nor does it advocate password aging.

    The Group File

    The group file contains a listing of entire of the groups on the system, along with each group's numeric groupid and a list of each of the usernames that are secondary members of each group. The location of the group file is /etc/group. The format of the group file is:

    groupname:password:gid:user-list

    These fields are:

  • groupname—this is the denomination of the group.

  • password—this is an optional password for the group.

  • gid—the unique numerical ID assigned to the group. The maximum value for GID is 2147483647, but administrators are urged to expend values less than 60,000 to ensure compatibility with entire of the tools that are used to manage accounts or display information that includes group names.

  • user-list—a comma-separated list of users allowed in the group. These groups are users' secondary group IDs.

  • A sample group file follows.

    root::0:root other::1: bin::2:root,bin,daemon sys::3:root,bin,sys,adm adm::4:root,adm,daemon uucp::5:root,uucp mail::6:root tty::7:root,tty,adm lp::8:root,lp,adm nuucp::9:root,nuucp staff:GSSUYVrJ8EKyA:10:pete daemon::12:root,daemon sysadmin::14: nobody::60001: noaccess::60002: nogroup::65534:

    Note the password province in the group "staff." Groups can live password protected by putting a password string into the password field. Note, though, that this is a completely manual process; there are no tools provided to set the group password in for you.

    Hint: You can capture a password string from the shadow file and expend the vi editor to splice it into the group file. The group password will live the very as the account password from the shadow entry where you took the password string.

    When a group is password protected, anyone who is not a member of the group will live challenged for the group's password when they beget entered the newgrp command.

    Primary and Secondary Groupids

    Each user account has one primary groupid—this is the group defined in the password file. When a user logs on, this is his or her associated groupid.

    Each user account moreover has zero or more secondary groupids. A user's secondary groups are those group entries that include the username in their lists of members.

    There are some useful limitations of groupids. For example, each user account can live in no more than 16 groups, and a line in the group file cannot exceed 512 characters (including the newline character).

    What happens if you necessity to add so many members to a group that you exceed the 512-character entry limit? You simply create another duplicate group entry—same denomination and group number—and list the additional members there.

    The primary and secondary groupids directly repercussion file system access permissions, which is explored fully in Chapter 10.

    Exam Notes

    Think About It . . .

    What would live the result if a username were added to a group file entry when that group was the user's primary group?

    The additional entry would beget no effect, since the user is already configured for the primary group membership in the /etc/passwd file.

    The Root Account

    The root account has special privileges on a system: Root is permitted to read and write every file on a system, regardless of the file's ownership and permission settings. System administrators log in with the root account so that they can achieve administrative tasks.

    The root account gets its power and privilege from the value of its user number: Root is user number zero, defined in the password file.

    Exam Notes

    Think About It . . .

    What would live the effects of changing an ordinary user's user number to zero? What handicap might there live of putting root's entry at the conclude of the passwd file (instead of the beginning)?

    Changing an ordinary user's user number to zero gives the user root privileges.

    One handicap of putting root at the conclude of the password file is that if an intruder is able to modify the password file to give another user root privilege (see the first question here), then output from commands such as ls and ps would complicated that other user as the owner of root processes and files.
