Sysadmin Toolbox Top Ten

Posted by ryuzaki0 on from the pick-your-poison dept.

Linux.com is running a user writeup of several handy tools by an up-and-coming Linux user. It is always interesting to see how newer users are approaching system customization. What have some of the more seasoned Linux power-users and sys admins put in their "toolbox top 10", and why?

  2. Nothing to do with systems administration by ximenes · · Score: 5, Informative

    As the author even says in the first paragraph of the article, this is totally not a systems administrator's toolbox. BitTorrent clients, music players and tail aren't super helpful in making disk quotas or setting up DNS.

      Which ligitimacy are we talking about? I agree that these don't have much to do with administrative tasks, but bittorrent clients and media apps aid in trying to make Linux a legitimate alternative to Windows for desktop users. Linux is already established to be good for sysadmin uses.

      I don't think the goal of Linux is to be Windows-like(or OSX-like). I don't think the goal of Windows is even to be Windows-like. I think the goal is to effectivly perform a variety of tasks for as many people as possible. For sysadmins, they won't neccessarily use media tools. But for my Mom who may want the occational torrent of a show she missed or to watch a home movie clip I send her, these apps make or break the legitimacy. It all depends on who we(Linux users) are trying to convince. Yes, the title is decieving, but the underlying message isn't. Linux has many great tools, and letting people know that should be the focus.

      This is one of an ongoing series of such articles, not the only one. So, yes, it is desirable for a certain class of reader to hear from someone who administers a large network, but since many people who ar enot professional sysadmins do in fact administer a machine or two (their own and sometimes others), it is quite reasonable to hear from people in other situations as well.

    also, rxvt has another cool feature. aside from its shockingly minimalistic memory usage, run urxvtd and then urxvtc for every term you need open and it uses even less memory. what could possibly be better than that?

  10. Tools for *actual* sysadmins by algae · · Score: 5, Informative

    The stuff posted in the article was alright, and given the guy is 17, I'll cut him some slack. However, as a professional sysadmin for the last 10 years, I think I can whip up a good list of my favorite tools.

    Bash. If you don't know how to write a for-loop in bash to connect to all your hosts and make some changes, you don't know what you're missing.

    SSH, with an agent and keys. If you get asked for the password every time you connect to a host with the above bash loop, you're missing on a very powerful tool. Passwords are a once-daily thing for me now, and that's only because my screen lock also kills my ssh agent.

    Osiris. Because you should know what's happening on the computers you maintain. File integrity monitoring is a Good Thing. File integrity monitoring with a client/server architecture is a Very Good Thing.

    Snort. Use snort. You have no idea what's happening on your network until you use snort. If you have desktop users, load up the bleeding-snort rulesets and be prepared to panic in horror as you see all the crapware flowing over your network.

    Perl. With bash-fu. Like this: $ perl -i.BAK -pe 's/(http://192/\.168\.0)\.2/$1.3/' `find . -iname "*.htm"` You'll never look at sed again ;)

    Finally, if you've got a boss who will let you, rip out those expensive proprietary firewalls and replace them with OpenBSD on a Soekris solid-state computer. OpenBSD pf is a joy to work with, and for VPNs, ipsecctl can't be beat. You can literally VPN two remote networks together in about five minutes.

  11. Re:ISO's by pla · · Score: 4, Interesting

    You're right - it's preposterous to think a sysadmin would want to download distro ISO's quickly.

    I see that argument a lot, but y'know, I can download an ISO of any major distro via plain ol' FTP or HTTP as fast as my cablemodem will let me. What exactly would I gain by using P2P, other than yet another open port on my machine just waiting for someone to find an exploit?

    Though, don't take this as an anti-P2P stance... P2P has its uses, and more efficient (for the server, not for any particular recipient) distribution of large files comes in pretty high on that list. But on this list, of the top 10 sysadmin tools - It doesn't come in at all. It duplicates funcationality (if via a slightly different mechanism) already present on a stock Linux box.

  12. Multitail! by anonieuweling · · Score: 4, Interesting

    Why wasn't multitail mentioned? MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of 2 or even more logfiles is possible. It can also use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. It can also filter lines (again with regular expressions). It has interactive menus for editing given regular expressions and deleting and adding windows. One can also have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch' and such.

We delt with millions of bookcover images and ImageMagick was a golden for mass manipulation of images. As for MP3 tools, I like my music why I work! Whats wrong with that?
