RE: VOIP experiences

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

command line acvice
by jgtgru 27 Feb '05

27 Feb '05

I recently installed Suse 9.2 and would like to become familiar with Linux and command line. My idea is to take on projects so that I can learn this in a hands on way, I am also open to suggestions. One simple project that I would like to start with is to get the sound enabled for my instant messenger. At present I have sound on most desktop applications, but certain applications are not included in the Control Center listing. My thought is to add the instant messenger to that list using the command line. Please advise. It's not the life that matters, but the courage we bring to it. jgtgru

Nope. Checked that. The image was several weeks old, and while an exploit may have been planted, then used at a later date, I think this is unlikely. Any traces of the actual cause of the file disappearence was lost with the restore. (Personally, I am a bit suspicious that the primary client may have screwed something up.) Having made a full restore and run for most of a week, hardware failure dosen't look likely, and the S.M.A.R.T. utils I subsequently installed don't indicate it. > Of course it could also be that the cracker is watching the > system and actively rooting it, so that when you re-installed > whatever method was previously used to crack the system was > used again in short order. That is a distinct possibility - not exactly short order, but we may be on his list of easy marks. Then again, while there is a certain amusement to be had it simply destroying a system, it's not the way most people spend a lot of their time. I suppose one of the clients on the server could have annoyed someone sufficiently to motivate a repeated attack. > So, in either case I think a little research is in order to determine > how to keep this particular bad guy out. Um, yes. I believe that's implied in my earlier query. In particular, there is the kernel update, and I will be looking for further ways to tighten CGI security, as well as looking for other clues. One plan I think is rather valuable is to simply run the server and watch it very carefully. _______________________________________________ Kclug mailing list Kclug(a)kclug.org http://kclug.org/mailman/listinfo/kclug

First, I don't know much about the business relationship, so this is all speculation. But I do see opportunity for $$, justified (pardon my politics) by fear, uncertainty and doubt about security. After all, they were hacked, files missing, and down for over a day. Who knows what else, forensics was not performed, only recovery. You said you manage the site. I presume you get paid. They didn't pay you enough to keep current with software versions. Their bad. But that is tempered by the understanding they had when they entrusted the site to you, do you 'own' the security? Did you give them assurances? Or was it overlooked and now a problem. If you have time (if you don't, subcontract it), figure out what needs to be done to update the box to current standards, including the web pages/apps (if you do those, or even if not) and send them a total estimate. They will 'negotiate', but mostly they need to understand: _this_must_be_done_ to prevent recurrence. They will pay if the website draws business to them (read: $$$$). Temper this suggestion by how important is it to them. I see money in your future with a serious reason for doing so [security]. Please include a monthly fee to stay current on software/apps (15-20% maintenance). You will take care of them better if they pay as a monthly customer, your relationship will be more important both ways. If you are doing it for a co-worker/friend/family or such, then I wouldn't be so harsh. But for arms length business arrangements, I'd say cha-ching. And it would be money well spent (on both sides).

Well, I'm no expert, but... since you apparently had already been hacked prior to the reinstall (evidenced by the rm -rf /), I would wager that your reload from the image you have here is already rooted. Of course it could also be that the cracker is watching the system and actively rooting it, so that when you re-installed whatever method was previously used to crack the system was used again in short order. So, in either case I think a little research is in order to determine how to keep this particular bad guy out. > -----Original Message----- > From: Jonathan Hutchins > > ...

Re: Trojan Found

Did you finally restore from backup or something? I didn't hear how you got it back up. You said it was in AZ or someplace far away. Just curious what got you to the point you could talk to the machine. These kind of stories are like trashy novels for geeks. Brian Kelsay >>> Jonathan Hutchins <> 02/25/05 01:50PM >>> I found a trojan running on my server today - rootedoor (http://vil.mcafeesecurity.com/vil/content/v_128116.htm). Couldn't find much information about it on the web. If you know anything specific about it (not general speculation on rootkits, trojans, etc.), I would appreciate you sharing it with the list. I detected it running as one of the last two processes listed by 'ps ax' just before a reboot to install a new kernel; the reboot seems to have eliminated all traces of it from the system. I found a number of missing or corrupt Perl modules on the system, but that may not be related, it's an old system and I've had some Perl issues before. This _is_ the system that suddenly lost all it's files Sunday night, so it could have been hacked before.
