Sysadmin Toolbox Top Ten 304

Posted by ScuttleMonkey
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?

      If anybody at /. could read, you would see that this is a long running series and that there is no requirement that there be ten tools specified. If they publish your list, you get $100.

      I've learned about quite a few interesting tools from this series. Some of the authors cite the old standbys - grep, and the like. But some of them have discovered some interesting tools I've never seen referenced before.

      Seriously, this is a list compiled by a 17 year old kid. He is a hobby user. While I grant that he has been a user for 6 years, an 11 year old has much different priorities than someone responsible for multiple users in a large LAN environment. Promoting this does nothing to aid the legitimacy of Linux.

        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.

    Since version 2.0.6.0, Azureus also works with multiple torrents on a single port.

    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/ [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.

    Why wasn't multitail [vanheusden.com] 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.

    By using Virtual desktops, having multiple tail windows open to view an appliation is not so bad.
