In a shop I worked in a while back, they were really strict about the tools. Any new admin coming in had to "prove themselves" before they could use the canned tools. So you did everything by hand, until they (the Sr. Admins) were convinced that you actually knew what you were doing. "Then" you could use the tools. Actually, not a bad thing. At least you knew that the people you were working with could actually handle an extreme situation if one came up. For example: It's 2:00am, and the server is down. You get woke up by the pager (damn, why does it always go off when "I'm" on call?!?). You scurry into the data center to find the server a smoking hulk. (For this example, let's pretend it's a Linux server). You manage to get it running by booting it from a CD, but you can forget X. You're on an ASCII terminal. At this point, you're looking at a text screen, and the only thing mounted are temporary filesystems that the boot process created when you booted it from the CD. You need to find your drives, get them mounted, and make a working environment. All that before you can even try to figure out why it crashed in the first place. And that slick GUI is hours away... --- GUI's are nice. But they're no substitute for knowing what's happening under the covers. It can mean the difference between reloading a box over something minor, or being able to get through the trial by fire above, and save the box.

[expert] Forwarded Message: Netwatch SRPM compile errors
I don't know how many of you guys out there use Netwatch -- http://www.slctech.org/~mackay/netwatch.html But for those of you who don't, it's a very powerful tool for monitoring udp and tcp connections to and from your system. It can show all connections either by their human or machine names (your choice), and offers a wealth of info on them. It is different from alot of the newer less functional GUI traffic analyzers in that it is operable from the console, with a much larger level of functionality than many of it's GUI cousins. It pretty much shows everything. Real handy for possibly unsolicited connections. Lately I've had compile errors while attempting to create a new RPM. I emailed the author with some info on the compile errors and he was so kind as to give me a fast reply regarding exactly how to fix the problem. I thought this was an excellent candidate for the expert list.

[expert] Using TCT...help
Tlug'ers and Experts, My question is based on a question from a book that was suggested to me by many admin's "Its called "Linux Adminsitration Handbook" by Evi Nemeth, Garth Snyder and Trent R.Hein. I've finished chapter 2 and now its exercise time. Most of the exercises in this chapter were simple until this one came up.. using mactime.. Run mactime to create an initial database of the time stamps associated with your system files. (done) Re-boot your machine (done) Run mactime again and determine which files have been modified by booting the machine. Which files were accessed but not modified? (Requires root access.) My problem (question) is how do I determine which files have been modified?? I'm not sure but I THINK the diff command is used here... again.. not sure.. Because of this book, I'm really starting to feel like a Sys Admin.. not somebody who has 8 computers online just to surf and get e-mail!! I'm using Linux in a nutshell to check my command usage but still not sure.. please advise.. thanks for your help and May the Lord keep your systems up and files in check!

Make the script suid root... (e.g. chown root:apache script.pl ; chmod 4750 script.pl ) Be careful. This is very dangerous.

Just one that tends to intimidate new admins because "the system" as you know it, isn't there. You're working from a bunch of temporary mounts. It's actually not that big a deal to fix. Just a royal pain in the ass because it always seems to happen at 2:00am, when "I'm" the one on call.. LOL I just finished doing a similar one on an IBM. The box wouldn't finish booting. So I couldn't get to the console. We had to string a serial cable to it, and get an ascii terminal running. It turned out that the system had crashed, and true to AIX, it was trying to write a report out to tape to send off to IBM (they're so helpful!). But since there was no tape in the drive, it couldn't, so it hung. Trouble was, it wasn't booted far enough to reach the console, so the only way to cancel the hung job was via an ascii teminal. Once the job was killed, the box very happily finished booting, and all is well. . But without knowing how to set up a quick ascii term, and run without a GUI, I'd have lost the server over a trivial thing. It just pays to spend the time to learn to do things without the GUI. GUIs are nice. I agree. There are times that I still use them. But in *nix, there are times when it just isn't there. Personally, I'm not that fond of rebuilding systems. It's one thing with a desktop, it's another entirely to loose an enterprise server. ;) Anyway, I'll get off my soap box.

[expert] Need Help aboyt hardware - off Topic...
Hi! I work at an institute of physics here in Argentina. We will receive some money from a foundation in Germany to buy some machines to use in numerical simulations and we want to build a cluster with them. We already have a cluster (we have 20 PII 500-400 and 15 Durons 700 and some Athlon 1 and 1.2 Ghz) but right now I'm a little behind the wave about hardware so I ask you guys some hints about the lasts compatibility problem that could arise with linux and the new hardware. For example I hear that the last Intel processor Pentium XP have problems with linux ... the machine runs slowly ... thing like that. My boss in the group target to Intel/Amd of about 2GHz , lots of memory... and I don' t have a clue about the motherboard( I read about problems with some mother that included some chipsets ). May be some info about cooling (how many fans are needed). We have to buy the machines in Germany (that is part of the agreement) and then send them back to Argentina. I don't read german... that' s a problem. :0 So we need to buy this parts without contact them personally . If some of you could help me with some possible configurations , it would be great to receive that information. TIA ALF -- = Lic.

If all you're doing is adding rules and not removing, you could write the script such that it takes an IP as a parameter and adds that IP to the DROP list. That limits your vulnerability to "fail safe" - i.e. if somebody breaks in, they can only increase your security for you. Fail safe always leaves you vulnerable to DoS (e.g. they can set it to deny everything), but you don't risk loss of data/privacy.

[expert] xterm from mandrake to solaris box
Hi out there at the screens, I've got a borderline case here... I'm in the process of switching from a Windows environment to an Mandrake based one. Right now I'm struggling with the following problem: I want to connect with a xterm-Window from my Mandrake Box to a SUN Solaris box. I must use X since I want to start an X app located on the Solaris machine. I'm using a dual-boot workstation. On the Windows half with Hummingbird eXceed installed and used everything works fine and easy since years. Changing to Mandrake 8.2 I'm unable to figure out how to accomplish the same task. According to one of my LX books it should be as easy as using the following command: xterm -display 66.66.66.66:0 (assuming that 66.66.66.66 is the Solaris box' IP adress) But all I get is the following error message: /usr/X11R6/bin/xterm.real Xt error: can't open display: 66.66.66.66:0 (same holds true for variations of the -display option: -display 66.66.66.66:0.0, -display 66.66.66.66 etc.) I was assuming that remotely accessing an X-Server would be as easy as connecting with telnet or VNC to another machine.

If so, try this: Assuming the mandrake box is called host1 and the sun is host2: On the local Mandrake box type in an Xterm: xhost + host2 telnet host2 (login) DISPLAY=host1:0; export DISPLAY xterm & This should start an xterm on your local machine that's running on the remote.

Re: [expert] xterm from mandrake to solaris box
Hi! You should accept connection from X servers to your tty with xhost + in any xterm or konsole in the mandrake machine. (this accept from everyone.. use with care) More info man xhost XHOST(1) XHOST(1) NAME xhost - server access control program for X SYNOPSIS xhost [[+-]name ...] DESCRIPTION The xhost program is used to add and delete host names or user names to the list allowed to make connections to the X server. In the case of hosts, this provides a rudimen tary form of privacy control and security. It is only sufficient for a workstation (single user) environment, although it does limit the worst abuses. Environments which require more sophisticated measures should implement the user-based mechanism or use the hooks in the protocol for passing other authentication data to the server.

daRcmaTTeR,
Thanks very much -- it's a good start if not more!
I guess I'll find out for sure soon ;-) , but is that "if icmp echo
request == 'yes'" pretty close to the right syntax? (I assume it's
checking for success of the ping.) Hmm, I looked up man icmp and man
echo -- looks like I'll have to dig a little deeper or do an experiment
or two.
(Just for the record, I don't need (and can't use) the ifup command
(effectively) as the dial up modem is on another box (running under
dos). The ping should "kick" the modem (except that, occasionally, the
modem hangs up and "locks up" so it won't redial). I'll probably
arrange the script to ping, check for success, on success kick the
mailqueue, on failure wait, then retry the ping.)
So ("thinking on paper"), something like:
maxtries = 3 (??)
count = 0
start: ping ISP (with parameters to limit to say 4 pings instead of
continuous)
count = count + 1
if icmp echo request == 'yes'
then
fetchmail
sendmail -q
else
if count <= maxtries (wow, do I forget valid syntax ;-) )
then
wait 30 (??) (give the modem a chance to connect)
goto start
else
issue "Internet connection lost, could not restart"
message (somewhere)
fi
fi
I'll need to brush up on bash syntax and so forth, and if I'm clever I
might get rid of the goto.
regards,
Randy Kramer

How are you upgrading libmm1? If you're using -Fvh or -Uvh, you
shouldn't get this conflicts. I suspect this is part of the problem
you're having with openssl/mod_ssl as well.
Can you give me the output of "rpm -qa|grep mm"? Maybe you have two
instances of libmm1 installed which would give you this conflict on a
freshen or upgrade.

That said, I think what you're looking for is AMD right now (tons or processor/memory power) and there are finally some kickass boards out for the Athlon (thank god for the SiS 735 chipset!). I would very, very, very strongly recommend the dual-Athlon system as descibed by the folks from hardwareguys over at http://www.hardwareguys.com/guides/smp-amd.html. My only personal advice is to wait until after AMD drops their new "Hammer" series of processors, particularly the Opteron Sledgehammer and Opteron Clawhammer DP (the server-class line). Once those are released 3-5 months from now you will be able to find Athlon MP processors and appropriate mobos for bargain basement prices. Good luck shopping and I strongly urge you again to check out the link to www.hardwareguys.com because they are the most informed and trustworthy people in the business, they also are amazing at responding to email if you have any questions.
