Modern 64-bit installs do not install all the 32-bit runtimes needed to run 32-bit programs, so having to use a 32-bit program can be painful, give you'd need to install a bazillion other files just to accommodate that one proggy. -- ------------------------------------------------------------------------------- .---- Fred Smith / ( /__ ,__. __ __ / __ : / / / / /__) / / /__) .+' Home: fredex(a)fcshome.stoneham.ma.us / / (__ (___ (__(_ (___ / :__ 781-438-5471 -------------------------------- Jude 1:24,25 ---------------------------------

Please shed a light: when sssd will return from offline to online?
by Gelen James 05 Mar '13

05 Mar '13

Hi all, I'm new to sssd configs and debugging. Recently we have encountered some problems with sssd. Basically 6 out of 50 servers has 'getent passwd' lost all userIDs from LDAP backend, while others are OK. My sssd is at version 1.8.0-32. the related error messages are attached below. The sssd_nss seems got killed by temporarily network connection problems to backend openLDAP servers. Wonder why? and can we change the backend retry check interval? (see the timestamps for log entries in sssd_nss.log). [root@testbox sssd]# cat sssd_nss.log (Sat Mar 2 02:30:41 2013) [sssd[nss]] [sss_dp_init] (0x0010): Failed to connect to monitor services.

what does the strange sssd log mesages mean?
by Gelen James 05 Mar '13

05 Mar '13

Hi all, I have a few centos 6 boxes running sssd, they are talking to OpenLDAP server still runs on centos 5. Today I enabled sssd debugging and found the following lines of messages in logs: ... (Mon Mar 4 23:11:13 2013) [sssd[be[ldap]]] [get_naming_context] (0x0200): Using value from [namingContexts] as naming context. (Mon Mar 4 23:11:13 2013) [sssd[be[ldap]]] [sdap_get_server_opts_from_rootdse] (0x0200): No known USN scheme is supported by this server! (Mon Mar 4 23:11:13 2013) [sssd[be[ldap]]] [sdap_get_server_opts_from_rootdse] (0x0200): Will use modification timestamp as usn! ... what does the above messages mean: why it uses modification timestamp as usn? does that have some harmful effects, if time drifts /time zone difference exists in a network? Please shed a light. Thanks. --Gelen

I did NOT set up proxy, and I was being pounded, and found I had to turn it off. Now knowing what to look for, I found my notes and it was back on my '07 server. There is no reason for a general web server to function as a proxy, so for some time it has come with that part commented out. I looked a another '10 box (Centos 5.5) that had apache installed but never used and the proxy part was commented out. So yes, anyone turning on proxy today without care gets what they set up. But again, who needs proxying on a general web server?

RAID MD10
by m.roth＠5-cent.us 04 Mar '13

04 Mar '13

I'm going to rebuild my system at home soon, and was planning to mirror two drives. However, I was just looking up something about RAID, and on wikipedia found some information about the Linux MD driver, and "near" and "far" RAID10. Anyone have some opinions about them? mark "or should that be how many opinions do folks have about them?"

GUI volume control/mixer in C6??
by Fred 04 Mar '13

04 Mar '13

Just bringing up a Centos-6 (x86_64, FWIW) and I can't find the mixer app... on my C5 box(es), double click on the speaker icon in the top panel and I get a mixer app appears on the screen. My new C6 box doesn't do that. I've installed all the PULSEAUDIO RPMS I can find, but still nothing. what am I missing here? thanks! Fred

problems with .forward
by Robert Moskowitz 04 Mar '13

04 Mar '13

My old Centos 5.5 servers had a /root/.forward to send things like logwatch to this email account. It did not take any special configuration in sendmail for this to work. Now Centos 6.3 is using postfix (as we well know, and generally I am happy for this) and I have set up the /root/.forward as always, but it seems like postfix is ignoring it. I have restarted postfix with no difference in behaviour. /root/.forward contains the single line without ending in <cr> (I have tested with <cr> at the end as well: rgm(a)htt-consult.com 'host htt-consult.com' responses with: htt-consult.com mail is handled by 10 klovia.htt-consult.com. For the testing from my regular account I run: mail -s Test root < /dev/null /var/log/maillog shows: Mar 4 10:16:04 onlo postfix/pickup[30442]: 911731400CE: uid=500 from=<rgm> Mar 4 10:16:04 onlo postfix/cleanup[30526]: 911731400CE: message-id=<20130304151604.911731400CE(a)onlo.htt-consult.com> Mar 4 10:16:04 onlo postfix/qmgr[30443]: 911731400CE: from=<rgm(a)onlo.htt-consult.com>, size=471, nrcpt=1 (queue active) Mar 4 10:16:04 onlo postfix/local[30528]: 911731400CE: to=<root(a)onlo.htt-consult.com>, orig_to=<root>, relay=local, delay=0.15, delays=0.08/0.01/0/0.06, dsn=2.0.0, status=sent (delivered to mailbox) Mar 4 10:16:04 onlo postfix/qmgr[30443]: 911731400CE: removed You have mail in /var/spool/mail/root Does anyone else use the .forward file? This should work. Of course I can modify the alias file for postfix, but .forward was always 'easier' to configure. If I have to plow through the postfix docs for this, I will, but I would think this should work.

OT? : Big Yellow Cursor
by Beartooth 04 Mar '13

04 Mar '13

Last time I had a machine running CentOS (6.2 iirc) I had managed to get a big yellow arrow to show the mouse cursor. It was wonderful. Now I have machines running Fedora (17 & 18) and Puppy (5.0) -- and I need cursor symbols that my antiquated eyeballs can spot even through trifocals. Can anyone tell me a way to get my arrow back?? -- Beartooth Sciurivore, Curmudgeon On Line Viruses, trojans, and spyware, Oh My!

It includes firstboot! Easier just to disable it after install as I have been doing. Just thought I could prevent it from installing in the first place. I can put a %post in to turn it off at least.
