iSCSI ini and ESX Server
by Joseph L. Casale 02 Oct '08

02 Oct '08

I always used IET on CentOS but I have a quick server to setup to backup some VM's, then migrate to DAS on another server and the easiest way for me will be to accomplish this via iSCSI vmfs stores. I figured I would just use the ini that ships with CentOS but have never used it against ESX, anyone do this and have experiences they care to share? Should it be trivial or are there any non standard configs that need to be used? Thanks! jlc

Services take a long time during initialzation (LDAP-authentication)
by Bernhard Gschaider 02 Oct '08

02 Oct '08

Hi! I've got a CentOS4.7-machine as a fileserver. The machine also serves as the LDAP-server against which all regular users are authenticated. The problem I am having is that the machine takes a very long time to boot. Most of the services start up rather quick, but three services take quite a long time (extending the boot time to over half an hour, which is .... long) The three services are (in that order): - NFS statd - LDAP - NFS quota As soon as the LDAP-Service (and sshd) has started I can remotly log into the machine: the rpc.quotad has started but takes no CPU-time (so I guess he must be waiting for something) Some other observations I had: - a restart of LDAP takes several minutes - if the LDAP-service is down a "su ldap" (ldap IS in /etc/passwd) seems to hang. The ldap-service-script does such a su to check the configuration so I guess that is what takes the service so long) Could anyone give me a hint what the problem could be and how to fix it? Is any more information required (don't want to spam you with the nsswitch.conf and the whole pam.d-stuff)? Bernhard

Re: Moving folder just vanished??

Thanks for both of your responses. Sorry for the non-threaded post, but I'm e-mailing from somewhere else. @ Mogens Kjaer I have tried this already @ William L. Maltby I have looked everywhere on the drive using programs such as 'find'. I have ran: $ find / -iname "*.jpg" -or "*.JPG" and the missing files are now listed. I know enough to be able to find files. This is whats got me because I've never know an ext3 fs to do this; unless it's a bug with fuse-encfs.

Keeping a complete CentOS mirror
by Chris Miller 02 Oct '08

02 Oct '08

Is there a way I can keep a complete mirror of old/new releases of CentOS 4/5 automagically? In other words I would pull the old files from the vault site when needed, and new files from one of the other mirrors. I've seen/used a few scripts but rsync just stomps the old releases with the latest. The key issue here is having new release detection happen programmatically so I don't need to manage it once it's setup. Before I reinvent the wheel, I just wanted to see if there was a known method of accomplishing this. Q. Why? A. Because I have customers that need access to older OS builds as their products do not move as quickly as CentOS. Thanks in advance. Chris

Is there a way to configure yum fastest mirror to only look for http mirrors not ftp? I have tried adding ftp and ftp:// to the exclude section in the config file with no luck. Any info would be much appreciated. Thank you -- Bo Lynch

Flaky graphics - need help nailing down the cause
by MHR 02 Oct '08

02 Oct '08

This morning I noticed that my (new in July) monitor was behaving strangely. At first, it was odd parts of web page graphics that didn't show up unless I scrolled up and down in the window, and then they weren't displayed with any consistency. Then I noticed that the screensaver failed to appear (computer was locked, but graphics never showed on the monitor). I tried running mplayer to play a movie I have on the system, and the window remained black (sound was fine). When I move a window, parts of it (pixels scattered across the window) don't refresh during the move OR even when it is done, unless I run the mouse over them or, in the case of the menu bar, click on one of the options. The nautilus window that sometimes comes up after a reboot was not fully painted with the text parts of the entries below the mouse cursor on the screen until I ran the mouse over them, and then only the ones I "touched" refreshed properly. During the system shutdown and restart, the text is scrambled beyond recognition, although the graphics during the boot, driver init and login screen are fine. Most of the screen after I log in shows up, unless the default terminal and nautilus windows show up, and then they're not all there (as above). DVI-VGA: same problem either way 2.6.18-92.1.10 - 92.1.13: likewise (makes no difference) The video card is an nvidia ge7100gs and I have the beta driver from rpmforge (under dkms). The base system is an ECS nFORCE4M-A with an AMD Athlon 64x2 and 4GB of OCZ main memory. The newest parts are the main memory (upgraded from 2GB about two months ago) and the monitor (new in July). The m/b, COU and graphics card are all about 18 months old. I recently upgraded to the new 92.1.13 kernel. Question: Is this the monitor (most likely), the video card, the OS or the base system, or something else I have not considered? Is there a good video test program I can use to diagnose this properly? I have a two-year replacement warranty on the monitor, so I will use it if I need to, and I think it's still under the manufacturer's warranty anyway. Thanks. mhr

XDMCP - no GDM login, only gray screen with X
by Sean Carolan 02 Oct '08

02 Oct '08

I'm having trouble getting the GDM login screen to show up when I connect from a remote host. I'm using Xming on the local Windows machine, but every time I connect to the remote server all I get is a gray window with the X cursor. I have "Enable=true" in the [xdmcp] section of /etc/gdm/custom.conf. IPtables is disabled. I've googled around and read through the xdmcp page on tldp.org but have not come up with anything. Can anyone help with this issue?
