probes on udp port 500
by Aleksandar Milivojevic 05 Aug '05

05 Aug '05

Last couple of days some of my hosts were probed for UDP port 500 (IKE daemon, used by IPSec for key exchange) from dialup IPs. Don't remember seeing similar probes before. Some new vaulnerability that script kiddies (and pro crackers) are trying out, or is this some old stuff? I do remember there were some security problems with racoon in the past (that were fixed in current CentOS ipsec-tools packages), but don't remember reading anywhere there were any automated tools to exploit it floating around. Or are there some new flaws discovered recently in some IKE implementations? ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Modify rescue mode boot?
by Alberto Gonzalez 05 Aug '05

05 Aug '05

Hi, I have been able to boot with pxe and load linux rescue, it loads loader and ask me lang, keyboard,load base from nfs, etc... then it ask me about mount chroot or skip, I just choose skip to go to shell. What I want is boot in rescue mode and get a shell directly without having to enter lang, keyboard, nfs ip and dir, skip, etc... once booted on shell I want it automatically run a script mounted via nfs /mnt/source/myscript p.e. any idea on how to avoid all those questions from rescue mode?? Thanks.

remove RPMs with cyclic dependancies.
by Dave Gutteridge 05 Aug '05

05 Aug '05

Okay, I tried installing OpenOffice beta, and I think I messed it up, so I wanted to uninstall it. I thought wilcards worked, so I tried: [root@localhost program]# rpm -e openoffice* error: package openoffice* is not installed Okay, so I couldn't figure out how to remove a bunch of RPM packages at once, so I did this: [root@localhost program]# rpm -qa | grep openoffice And proceeded the labourous task of removing all of the RPMs listed one by one. But then I got down to some files that would say: rpm -e openofficeorg-core01-1.9.122-1.i586 error: Failed dependencies: openofficeorg-core01 is needed by (installed) openofficeorg-core08-1.9.122-1.i586 So then I'd remove the dependancy, and guess what?: rpm -e openofficeorg-core08-1.9.122-1.i586 error: Failed dependencies: openofficeorg-core01 is needed by (installed) openofficeorg-core01-1.9.122-1.i586 The two packages are dependant on each other so I can't remove either. *sigh* So, how do I remove them?

And now onto the palm pilot with Kpilot
by Dave Gutteridge 05 Aug '05

05 Aug '05

I've looked up the Kpilot manual, and I think I have an okay idea of what's going on with it. I'm trying to get it's detection feature to find my Palm Pilot. CentOS does seem to be able to recognize it, because if I run lsusb when running a hot sync, I get the following: [root@localhost dev]# lsusb Bus 001 Device 010: ID 0830:0060 Palm, Inc. Palm Tungsten T / Zire 71 That's encouraging. My Palm Pilot is actually a Tungsten E, not a T, but I'm not sure that's a level of detail that matters at this point. The Kpilot documentation suggest that I look for the palm pilot at /dev/ttyUSB0. That didn't work, but I noticed in my /dev/ directory that there was also a ttyUSB1. That didn't work either. But then I noticed that both were only apparent when I was hot syncing my Palm, so they must be connected to it. Any ideas, then, as to why Kpilot is not acknowledging them as a Palm device the way that lsusb does? Dave

Is this message from YUM a bad thing?
by Dave Gutteridge 05 Aug '05

05 Aug '05

I was doing a YUM update, and it found about 70 packages to download and install. While installing, this message popped up a couple of times: /sbin/ldconfig: File /usr/lib/libk3bdevice.so.2.0.0.#prelink#.X8kEMh is empty, not checked. And then after about three or four times of saying that, the YUM update stopped without finishing. So I started it again, and it picked up where it left off, so I figured it was no big deal. Then, about mid way through, it did it again. I went through this process a couple more times, and eventually it updated all the packages. But what does it mean, and is it significant? Should I care?

hda dma seek errors
by BRUCE STANLEY 05 Aug '05

05 Aug '05

I am getting occasional seek error on my boot drive. The messages are as follows: pshda: dma_intr: status = 0x51 { Drive ReadySeekComplete Error } hda: dma_intr: error= 0x84 { DriveStatusError BadCRC } ide: failed opcode was: unknown Everything seems to be working fine but these errors do have me concerned. The last time they occurred I was created a fairly large cpio backup file in the '/tmp' directory. The drive has been checked via fsck, and any errors found were reported to be corrected. Should I take some kind of action on this, or just ignore the errors?

Welcome screen is crashing.
by Dave Gutteridge 05 Aug '05

05 Aug '05

Hmm... it was tough to get into CentOS this morning. I booted up, and after the screen flickered a bit, I got an error message that said some png file couldn't be found (Sorry I was in a bit of a panic and didn't think to copy down the whole error message verbatum). I think it was "throbbing.png", which is a little salacious sounding, but that's what it was. Anyway, it says this image can't be found, and there's nothing else on the screen but the error message and a button to click "OK". So I click it, and nothing happens. Ever. No matter how many times I say Okay, it just sits there. So I tried restarting X, using my newly learned ctrl-alt-backspace key sequence. When X comes back, same message. Because I can't think of anything else to do, I try ctrl-alt-backspace a bunch of times in a row, and then after a few times, the error message changes. It says "X seems to be crashing. I will try to restart with a different greeting screen". Fine by me, so I click "OK", and I get this really plain, light blue and grey login screen. I login with my usual personal account, and I'm in. I don't want to go through *that* again. But I'm not sure what the issue is. I was doing two things last night. One is install OpenOffice Beta, which, after help from this list, finally worked. I was also wanting to install new themes for KDE, but that didn't get far as I downloaded one theme, and I couldn't get past the ./configure part because I didn't specify the right perameters or something. But in the process of trying to figure out why the ./configure failed, I attempted to update KDE following instructions on their web site. Part of the exercise was to get qt installed, as the theme seemed to require it. But all I did was add a repository from the KDE site and do a um install of some KDE related programs. There is one other thing that I notice about my system that's different. In the top left hand of my screen, on my panel, the CentOS logo is gone, and in it's place is the icon for a "Prominent North American Linux Distributor". Where'd *that* come from? Dave
