Building RH7.3 server after 7.0 hacked
by Richard Goodman 28 Oct '02

28 Oct '02

As some of you may recall from a mid-week email, two of my RH7.0 servers were badly hacked Tuesday about 5AM, and I lost ssh and think I received a trojan. Friday the hacking got worse - all outgoing mail was rejected as "relaying denied", so I decided to bite the bullet and format the drive and build a new server. This was made more interesting by the fact the RH7.3 wouldn't finish loading packages until I disconnected my second HD which previously held /var, and my web sites (tried 3-4 times) .. "Kernel unable to reread partition table on /tmp/hdc (device or resource busy)", then hung mid-package loading. Late Saturday afternoon I pulled the plug, and started a RH7.3 install. Midmorning I was done, including security patches and had no internet connection .. couldn't even ping from the server. Fortunately, it was just my ISP picking this time to be down for the first time in months. Now I have one remaining problem which over 8 hours of work has clarified, but not solved. For background, I have the just rebuilt RH7.3 server (A), and two other recently built RH7.3 servers (B) and (C) at a different location and each with its own static IP#, all running sendmail for one or several domains From A - incoming mail seems to be fine From A - I can send mail locally to several domain names that are on the A server From A - I can send email (such as this) out into the world Through A - I have several email addresses which are accessed by others from outside and send mail to another outside address in virtusertable or to an alias which is a list of outside addresses, and these are working From A - I cannot send mail to any of the domains at B or C When I try, I get this on the A sendmail log: Oct 27 19:02:56 bach sendmail[3693]: g9S02uO03693: from=<dick(a)goodman1.net>, size=316, class=0, nrcp ts=1, msgid=<p04310101b9e23f71eb3e(a)[192.168.1.9]>, proto=ESMTP, daemon=MTA, relay=host9.goodman1.net [192.168.1.9] Oct 27 19:03:02 bach sendmail[3695]: g9S02uO03693: SYSERR(root): 11harvard.com. config error: mail l oops back to me (MX problem?)

RE: [Wlug] Installfest

I have successfully booted into windows but found some interesting behaviors along the way. It appears that I must have swapped the hard drives at some point. The latest OS resides on hda1. Using YaST2 I added another boot definition pointing to windows on hdb1. FYI...YaST behaves differently when launched from within X than when launched from a shell with no X. After rebooting I get the lilo prompt to select an OS. I select windows and am then presented another lilo prompt (SuSE 7.0?) to select an OS. After choosing windows a second time, windows is successfully launched. This accomplishes what I need...but it would be nice to understand what is happening so I could get rid of the second OS prompt. Obviously I have done several installs on my system onto different drives. I have read the man page for lilo.conf and understood only a fraction of what it was trying to tell me. Can someone point me to some other resources that will help me to understand what is happening during the boot process? Thanks > Mike, > > You're almost home free. Take a gander at /etc/lilo.conf.

howdy cats... i must apologize for my lack of attendance to the install fun. sheesh. life is throwing me a bucket of hell lately and i gotta move out of my apartment by the end of next week - thus, i've been quite busy. if there is anyone who would still like a copy of something new (ala debian, gentoo, mandrake) all you gotta do is drop me a line. i have plenty of extra cd's and all i ask in return is that you give me some blanks. peace guys. -jeff btw, if i haven't mentioned it already, the new debian is really slick. tight and stable. that's a biased opinion. :-)

RE: [Wlug] DRM/TCPA/Palladium
by Keller, Tim 25 Oct '02

25 Oct '02

The problem I see is when you go out and buy a PC, blowout the partitions that have "longhorn" (MS's next OS) and install linux, reboot the machine and get this error at the POST screen: "TCPA Error: BOOT DEVICE DOES NOT CONTAIN VALID BOOT KEY" I don't see the people building the whole DRM infrastructure giving out details on how to change keys since their whole authentication infrastructure is based around the idea that every machine has a unique key so they can track things on a PC by PC basis. In their view, the idea of installing an operating system that doesn't have DRM built into it at the kernel level is an unacceptable option. The only way for DRM to be effective is to have a say in every action on your machine. Start an application and "DRM" verifies that the application is allowed to run on the machine. Insert a piece of media and "DRM" verifies that your allowed to access it. Go to a particular website and "DRM" decides if your allowed to access said website... On the privacy side of this, what's to keep the whole infrastructure from also keeping detailed info on what apps/media/peripheral/websites you access. Yeah, you could opt out of it, but by not opting in, your PC becomes utterly crippled, unable to play DVD's (since it can't verify authenticity), unable to run verified apps, etc... I see all kinds of other very onerous privacy issues with this...

I just started using arkeia the other day, and I'm rather impressed so far. They give you a 2 client license of version 4.2 for free (so you can backup the server, and 2 linux or windows clients) if you're using a linux backup server. You can make backups to tape or disk with it. Plus it has a little bit of eye candy; while backups are running, you can log in with the gui client (java client that works on a bunch of platforms) and see the speed at which the backups are running in a speedometer style display ... Hey, what can I say, I like pretty things :) I'm not sure if this is feasible at all, but could you use software raid and mirror your normal disk to the removeable one? Just a wacky solution that I thought of when someone mentioned LVM ... -Marc -----Original Message----- From: Andy Stewart [mailto:andystewart@attbi.com] Sent: Friday, October 25, 2002 12:04 AM To: wlug(a)mail.wlug.org Subject: Re: [Wlug] backup recomendation On Thursday 24 October 2002 9:55 am, Karl Hiramoto wrote: > What do people out there use for backup tools.

backup recomendation
by Karl Hiramoto 25 Oct '02

25 Oct '02

What do people out there use for backup tools. Anyone use Amanda? Any good? My situation is I have three servers I wish to backup. The total amount of data to be backup'd is 40GB. I wish to do weekly or monthly full backups with daily incremental. Plan A: Monthly Level 0, weekly Level 1, daily Level 2 Plan B: Weekly Level 0, daily Level 1 Plan C: Monthly Level 0, weekly level 0, daily level 1 Then every month I'd like to take one of the full backups and put it away for long term storage. My backup media is a 120GB IDE disks in a removable drive trays. Take them home for off site storage. One thing I'm trying now is: rsync the three servers to the local 120 GB disk. From local disk create tar files. Bad part about it is I have to store an extra 40GB on the disk of local copies of the servers. I can't just tar over NFS, because the files on the server may be changing as the tar is created. Tar bitches when that happens. My optimal solution: keep all files on the servers. Possibly use a small local scratch area(1 G or so). Create local backups and store them to the 120GB removable disk. I would like to use free software if possible. Any suggestions? -- ¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø Karl Hiramoto <karl(a)hiramoto.org> Work: 978-425-2090 ext 25 Cell: 508-517-4819 Personal web page: http://karl.hiramoto.org/ Zoop Productions: http://www.zoop.org/ KTEQ Rapid City: http://www.kteq.org/ AOL IM ID = KarlH420 Yahoo_IM = karl_hiramoto ¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø This is now.
