OT: IBM and Dell rack
by Fajar Priyanto 31 Mar '11

31 Mar '11

Hi all, sorry for the OT. Is IBM and Dell 42U rack compatible in dimension, rails, etc? Can we put IBM servers into Dell rack? Google says it depends. Much appreciated if you can share your experience. http://www.server-racks.com/why-all-racks-are-not-created-equal.html Thank you.

nlockdmgr listen on privileged port
by Tim Dunphy 31 Mar '11

31 Mar '11

hey list! I am attempting to shore up some centos machines (ranging from centos 5 to centos 5.4) for pci compliance by changing the port that nlockdmgr listens on to function under a privileged port. So what I did was try to hardcode the port by editing /etc/sysconfig/nfs # TCP port rpc.lockd should listen on. LOCKD_TCPPORT=1011 # UDP port rpc.lockd should listen on. LOCKD_UDPPORT=1011 # And /etc/modprobe.conf alias eth1 e1000e alias scsi_hostadapter 3w-9xxx alias scsi_hostadapter1 usb-storage alias eth0 e1000e options lockd nlm_udpport=1011 options lockd nlm_tcpport=1011 and then restarting the pormap service. I've even tried restarting the network service, but unfortunately nothing seems affected: [root@stallion:/etc/init.d] $ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100021 1 udp 55394 nlockmgr 100021 3 udp 55394 nlockmgr 100021 4 udp 55394 nlockmgr 100021 1 tcp 33704 nlockmgr 100021 3 tcp 33704 nlockmgr 100021 4 tcp 33704 nlockmgr 100024 1 udp 786 status 100024 1 tcp 789 status Does anyone have any tips on how to get this to work the way I'm asking it to? regards ~ GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

32-bit compat-gcc on 64-bit CentOS?
by Alan M. Evans 31 Mar '11

31 Mar '11

Ugh. One of our internal servers crashed so bad I just went out and bought a new machine to replace it. The old server was Pentium-4 based and running CentOS-5. When I installed CentOS on the new machine, I used the 64-bit version, partly because that habit is almost automatic nowadays, and partly because the new machine has 6GB of RAM, so 32-bit seemed not very appropriate. Anyway, I've managed to configure every one of the old server's many functions to match on the new server but one: I need the 32-bit version of compat-gcc-34. (Or at least I need to be able to compile 32-bit binaries with the already available version.) I can't seem to do this; am I just missing something? In retrospect, installing the 64-bit OS may have been foolish. But it's too late now. I've spent several days installing/loading/configuring this system to the point it's at now. It would be a pity to have to start over completely just to enable this one (very critical) function. -Alan

It's been many years, but it seems that I have to receive a fax and might have to send one too. Is there a way to do this on CentOS 5.5? (Hope so.) tia. -- Anything is easy if you know how to do it.

Too Much Traffic
by Gene Brandt 30 Mar '11

30 Mar '11

I'm amazed at the postings. Many of the solutions to questions posted can be found on GOOGLE. Also UNIX, AIX, HP-UX, and Linux all come with man pages. o Before posting try reading the relevant man pages. o Research your issue with a search engine . -- Gene Brandt <brandtg(a)bellsouth.net>

by Roland RoLaNd 30 Mar '11

30 Mar '11

Hope this email finds you well. I need your advice with something if you can help out. I have an RC serer (selenium rc) which is running on a centos 5.2 and another on a 5.4 machine. if i run it through X server, in other words if i run the server while connected to VNC. it works fine. but if i run it through ssh, it will start normally though upon test execution it will fail with the following error: 11:05:01.571 INFO - Preparing Firefox profile... Error: no display specified 11:05:21.818 ERROR - Failed to start new browser session, shutdown browser and clear all session data java.lang.RuntimeException: Timed out waiting for profile to be created! 11:05:21.833 INFO - Got result: Failed to start new browser session: Error while launching browser on session null any idea how i can solve this? Thanks, --Roland

Centos+AD integration (uid/gid problems)
by nux＠li.nux.ro 30 Mar '11

30 Mar '11

Hi, I need to have several EL machines in an AD env. Joining the machines was easier than expected using authconfig, but what happens now is that blahdomain\blahuser gets assigned a different, random ID each time I use a different station. In AD I did specify the UID and GID in the UNIX Attributes tab for blahuser, but it gets totally ignored; so do the other values (for home, shell etc). Ideally I'd have all the users assigned a static uid and gid from AD and have /home on all machines mounted from NFS; but right now if I log in with blahuser to another machine my $HOME is owned by another random id. Sugesstions? What am I missing? I'm quite a noob with Windows :) Cheers

rssh / scponly
by Gregory P. Ennis 30 Mar '11

List, I am putting together a sftp server and would like to use a restrictive shell with a chroot jail. I was wondering what members of the list thought about rssh as opposed to scponly. Greg Ennis
