Out of memory problems - some interesting log file entries
by Brian Parish 16 Jun '05

16 Jun '05

This is a newly installed server running CentOS 4 with all current updates. It's been cruising nicely since installation a week ago until this morning. Then everyting started timing out and the attached messages appeared in the log (this is a short and sanitized extract). Load went sky high. Had to reboot to restore service and all looks happy again now, but if anyone can provide some input on these messages... TIA Brian

Serial Console + VGA Console
by Gerald Waugh 16 Jun '05

16 Jun '05

Hi, Trying to get vga console and a serial console to both work. I can get either one to fully work but not both. When using serial, I do still get a login prompt on the vga, But not all the boot up output. Seems like half to the vga and the rest to the serial port I added lines to /etc/inittab # console port T0:12345:respawn:/sbin/agetty -L ttyS0 115200 And added to /etc/lilo.conf append="console=tty0 console=ttyS0,115200n8" I tried to add to "serial=0,115200n8" lilo.conf, but this gives error unsoported baud rate, commenting the line out seems to work. Any ideas on how to get both VGA and serial console to fully work? Maybe, I can have one but not the other? Gerald

From: Mike Kercher <mike(a)CamaroSS.net> > Have you considered using VNC instead? I do this to just start an > xterm...from there I can run Mozilla or whatever. A nested X server is probably a better solution. Passing the native widgets over remote protocols is always going to be a better solution than using a dumb, pixel-by-pixel remote framebuffer. I.e., use RDP, X11, ICA, etc... when you have an option instead of pcAnywhere, VNC, etc... if you can. -- Bryan J. Smith mailto:b.j.smith@ieee.org

turning off prelinking?
by alex＠milivojevic.org 16 Jun '05

16 Jun '05

In short, the reason considering (and still only considering) turning it off is to make tripwire usable again (security vs. performance, I guess). Is it possible to completely turn it off system-wide? Any additional steps needed on the existing system (that already have half of the binaries prelinked)? What order of performance degradation to expect? If it is minor, nobody is going to cry about it. My old RH 7.3 systems don't have prelinking, and I don't see them being any slower than FC2 and newer systems that have prelinking... ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

16 Jun '05

Hi, Does anyone knows of a place where one can download through HTTP (and only HTTP) the CentOS 4.1 DVD ISO ? I'm behind a firewall and have no chance of either getting it through bittorrent or FTP. Any help would be apreciated. Warm regads, Mário Gamito

Big trouble: can't start server after new kernel
by Mário Gamito 16 Jun '05

16 Jun '05

Hi, I have this file server with CentOS 4.0 Each time a new kernel comes out, i have to recompile it, becuse i need Appletalk support and the kernel doesn't have it. I've done this before many times and in other servers, and all went well. Now, in this particular server, with the new 2.6.9-11, after i've recompiled it, created the .img and edited grub, the machine doesn't start at all. It says it can't find the kernel image. I cannot even boot with older kernels. To worsten things, i have LVM, so "linux rescue" tells me there's no Linux installation in the server and leaves me with a prompt. Now, i can mount /boot because it is outside the LVM, but when i do it, i lost access to any command, even a mere ls. Tried to pre-copy vi before the /boot mount and could access /boot/grub/menu.lst Everything seems fine, the files are all in /boot ...!!! Do i need to run grub command after editing menu.lst ? Never did that. And why can't i boot from older kernels ? Now, the really nasty thing: somehow, i don't have the smallest hint, i had a 500 GB external USB disk to make the backups, and the "linux rescue" erased it :( :( :( Bogles me!!! Please help me. This one can cost me the job. Loosing 300 GB of files from ~ 100 users on the file server is unforgiven. Any help would be apreciated. Warm Regards, Mário Gamito
