Those could also be mailed to Bill. He posted his address in here a week or two ago.

Server Fundraiser
by Brian Kelsay 01 Mar '05

01 Mar '05

At the regularly scheduled KCLUG Meeting tomorrow I will collect more funds for the LUG server upgrades. I believe we are about $60 from our goal so that bigger, better drives and a controller can be purchased. Chris Bier will not be present at the meeting and I'm not sure about Bill C., so I will make sure the funds get to one of them in time for the hardware purchase. Only give if you are able. Checks can be made out to Bill Cavalieri w/ a ref. to KCLUG Server Fund in the memo. Brian Kelsay

Do these 2 tools work with the standard .debs I grab when I update my PC? Still figuring some intricacies of Debian out.

I'm guessing no. Although, it might be possible to build an rpm database of installed software on a Debian box and then use that as an additional check. Of course there's nothing, stopping a cunning cracker from building an RPM database, setting the timestamp and copying it onto the cracked system. Something possible with Jonathon's box too. Jonathon, was your check done with a local copy of the RPM database, or an archived known good copy? Certainly, if I were a cracker, installing a new copy of the RPM database would be part of my initial and every subsequent loading of software onto a cracked system. After all, to be successful at cracking it best to remain undetected. Brian

I'm a niave person that has absolutely no knowledge of how to administer a server. That said, what is the possibiliy that the machine you rsync'd from has been compromised?

Yeah, you can update RH or Fedora with apt-get or YUM once you set up the program and point to the repositories. Apt4RPM is a bit easier than using RH update manager. I was always getting timeouts from the official RH mirrors during the day. Late at night would sometimes work.

Then keeping up to do wouldn't be so hard if you were using the debian package management. Doesn't FC3 us something like that to update? I have never actually used FC yet. Thanks, Jonathan

At the risk of sounding foolish, I'll jump in with my opinion. I' m no security expert either, but have learned something about security. I think your terminology for "rooted" is shall we say "creative". The fact the all of your files were wiped from the disk, and you seem to have ruled out hardware failure, the logical conclusion is that some process/user with root-level authority deleted all the files. The fact you discovered rootedoor after reinstalling doesn't preclude the possibility that it *was not* there before. I don't know the specifics of your machine and you certainly seem to know what you are doing, and I'm not suggesting you wipe your machine. I don't know if/why any of your clients have root level access, so if they do then it is certainly possible that one of them did it by accident, as you seem to think. I find it unlikely that some arbitrary process did this, and if it did then you need to seriously look at the uids that these processes run as. There is no reason for most programs and I see no reason for any web program to run with root privileges. I am curious though how the re-install was accomplished, seeing as how you live here in the KC Metro and the machine is 1000+ miles away in AZ, IIRC. I'd also like to say, that it appears by your numerous replies on this these threads that you take pretty good care of security, which makes finding out what might have happened more important. Since a successful hack might indicate a zero-day exploit, while it could also be highly likely that a local user's account has been compromised. Brian

Wouldn't this be a good time to upgrade then? Brian Kelsay >>> Jonathan Hutchins <> 02/25/05 05:22PM >>> On Friday 25 February 2005 05:10 pm, D. Hageman wrote: Unfortunately, with what is now a rather ancient distribution (RH7.3), it's getting harder to keep it current with RPMs.

Found this Slashdot article on VOIP and QoS this morning. There was some stuff I didn't know and some of the usually ranting and chaff. Take what you need. http://ask.slashdot.org/article.pl?sid=05/02/24/0024257 Brian Kelsay

I am not sure there is any command line options like that for gaim. I don't know why you want the sound stuff in Suse Control Center unless you want to control all at one place, but I think I would be too much and not worth it to do that. What is the sound notification option for anyways? Thanks, Jonathan
