I ran the following on the device: mkdir -p /boot/extlinux extlinux /boot/extlinux cat /usr/lib/syslinux/mbr.bin > /dev/sde cp /boot/vmlinuz.latest.kernel /boot/extlinux/linux I then attempt to boot it and it starts going however I says kernel panic no root device. What have I missed. I followed the instructions in /usr/share/doc/syslinux/extlinux.doc Thanks, Jerry

Best way to migrate a server?
by Kevin Thorpe 20 Aug '08

20 Aug '08

I was just wondering what recommendations you have on migrating a CentOS 5 install between servers? I've done similar in the past by setting up a minimal install in the new server, use tar to copy over the old install and reboot. I was thinking of rsync this time. Is that an acceptable thing to do or have I missed something important? thanks

centos on intel D945GCLF board
by Janez Košmrlj 20 Aug '08

20 Aug '08

Hi, I am trying to install centos on the intel D945GCLF board. It's a mini-ITX board with the atom processor and it uses the Realtek RTL8102EL LAN chipset. When I disable the on-board LAN card it installs and runs OK, but when I enable it, I get kernel panic at boot. The board runs perfectlj with Fedora 9 (with the latest kernel) or with Ubuntu server. My question is: is there some way to run centos on this board (test kernel, i can try for example)?

[Request] mod_auth_ntlm_winbind

http://adldap.sourceforge.net/wiki/doku.php?id=mod_auth_ntlm_winbind I have built an rpm for my own use, by grabbing the source files from sambas' web interface to cvs. It would be real neat to have it packaged and available through yum. -- Cheers, Morten :wq

Where is cached memory going?
by ABBAS KHAN 20 Aug '08

20 Aug '08

As by the time, I've learned that Linux works by caching apps by using a lot of RAM and then it reallocates the new stuff by cleaning the old cached pages from memory as compared to other OSs. With 2 gigs of RAM often I see the free memory only as 100-400MB. Using TOP or PS, it doesn't look like any program or process is using excessive memory (the highest process is seen with 1-2% total memory). *So, my questions are:* what programs are using that much of memory? (or cached memory) Is that really due to a lot of cache in the memory *if yes, then, is there a way to parse the cache to findout what applications are eating up the cache?* *how to free the cached memory?* *Currently, here are the details:* Top two high mem processes only using 2.6% of RAM. [root@Ether ~]# ps aux | sort -nrk4 | head -2 abbask 5922 0.0 1.4 364300 28312 ? S Aug19 0:00 /usr/bin/python -E /usr/bin/sealert -s ntop 4914 0.0 1.2 332752 24760 ?
