Re: [CentOS] Logwatch, cron, and dovecot
by Bob Hoffman 03 Jun '10

03 Jun '10

I think I found it...and I think it is a bug. Here is a file in usr/share/logwatch/default.conf/logfiles/cron.conf It appears this file tells it where to look for the cron file...and the cron file location is dead wrong. It should be /var/log/cron I believe. Is this the correct fix to make logwatch once again grab my cron files since 5.5 update? ########################################################################## # $Id: cron.conf,v 1.11 2005/02/24 17:05:18 kirk Exp $ ########################################################################## ######################################################## # This was written and is maintained by: # Kirk Bauer <kirk(a)kaybee.org> # # Please send all comments, suggestions, bug reports, # etc, to kirk(a)kaybee.org. ######################################################## # What actual file?

SUN Storage 7310 with RHEL 5.5 / Centos 5.5 and multipathed root, again.
by Jens Neu 03 Jun '10

03 Jun '10

Dear all, After some trouble finding the right multipath.conf, I'm running Centos 5.5 against the SUN 7310 more or less successfully now. Unfortunately one issue remains: the SUN 7310 has two storage heads, H1 and H2, which are in a active/passive configuration. If I define a LUN on H1, everything works great. I edit multipath.conf, re-create the initrd and I find 8 paths with active/ready and active/ghost: mpath0 (3600...0001) dm-0 SUN,Sun Storage 7310 [size=50G][features=1 queue_if_no_path][hwhandler=0][rw] \_ round-robin 0 [prio=200][active] \_ 0:0:0:0 sda 8:0 [active][ready] \_ 0:0:1:0 sdd 8:48 [active][ready] \_ 1:0:0:0 sdg 8:96 [active][ready] \_ 1:0:1:0 sdj 8:144 [active][ready] \_ round-robin 0 [prio=4][enabled] \_ 1:0:2:0 sdm 8:192 [active][ghost] \_ 0:0:2:0 sdn 8:208 [active][ghost] \_ 1:0:3:0 sds 65:32 [active][ghost] \_ 0:0:3:0 sdt 65:48 [active][ghost] Thing is: as soon as I set up a machine with the LUN(s) on the second head, all works well until I want to boot with the freshly created initrd/multipath.conf. System hangs with Kernel Panic, "Creating multipath devices... no devices found" and "mount: could not find filesystem '/dev/root'". Workaround: when I remove the paths to the passive ("ghost paths") Storage head in the SAN Fabric, the system boots fine and I can re-enable the paths when the kernel is up. The paths become [active][ghost] as wished after some time when they show up in the FC Zoning. This smells like broken mkinitrd to me. System is very up-to-date, Centos 5.5 Version below: [root@dev-db3 ~]# yum list device-mapper-multipath Installed Packages device-mapper-multipath.x86_64 0.4.7-34.el5_5.1 installed [root@dev-db3 ~]# uname -r 2.6.18-194.3.1.el5 Any suggestions? best regards from Berlin, Jens Neu Health Services Network Administration

Logwatch, cron, and dovecot
by Bob Hoffman 03 Jun '10

03 Jun '10

Howdy all, Question for anyone. I have centos 5.x on my server. Everyday I get a logwatch sent to my mailbox. I usually check every couple weeks and this time I got a surprise... Up until may 15th, the watch started with cron begin/ cron end and then went to http begin/end.... May 16th had the selinux (which I have disabled) and dovecot listings above the http begin. Cron was absent. Everyday after that is is all dovecot first, no cron. I never had dovecot show up in my logwatch before. So, I assume some update did something, but it was obviously 2 weeks ago or so. I have an auto update, so I am thinking it happened with a yum update. The selinux only happened that one time...not shown up since. I am concerned about the cron begin/end no longer being there, don't know why dovecot was not there to begin with.... Just did a reboot and will see what happens tomorrow... Thanks for any help at all. --------------------- Selinux Audit Begin ------------------------ Number of audit daemon starts: 1 Number of audit daemon stops: 1 **Unmatched Entries** Started dispatcher: /sbin/audispd pid: 21352 ---------------------- Selinux Audit End ------------------------- --------------------- Dovecot Begin ------------------------

pup problem
by Charles Campbell 03 Jun '10

03 Jun '10

Hello! On May 28, I had a problem with pup and seamonkey. I was doing an update via pup and reading a page via seamonkey; seamonkey froze with a plain brown screen. I waited awhile, and then did the press-the-power-button-until-it-shuts-off. However, I don't know whether it was seamonkey or pup that actually caused the freeze, but apparently pup did not do its updating job correctly. There's a number of icons that are missing, so (for example) open office won't start from the menu. Centos starts, but the desktop background doesn't appear (although I can select desktop background and get it to appear). Finally, attempts to attach anything to an email via seamonkey (17 or 2.04) or thunderbird show the requestor momentarily and then crashes seamonkey/thunderbird. Is there a log somewhere of what was updated (I didn't see it in /var/log/messages) and can I force pup to do the update manually? Any other suggestions for getting things back to normal? Regards, Chip Campbell

Can't print a pdf?
by MHR 02 Jun '10

02 Jun '10

I just had a strange occurrence. I was printing out some PDFs and I pulled one down off the web (my wireless bill) and tried to print page 1. My browser properly fired up AR9, but nothing printed. I tried agian, still nothing. I saved the file, opened it with the Document Viewer and it can't print the file either. I tried opening it with GIMP, and it gets this error: Opening '/home/mhr/Documents/pdfs/vzwA0418.pdf' failed: Plug-in could not open image I couldn't find any related data in the logs (spooler logs are all empty, nothing in dmesg). I tried disabling and enabling the printer, then turning it off and on to no effect (which is not too surprising). Anyone have a clue where I should look or what to do? Thanks. mhr

24G running on centos 5 desktop.
by Steve Brooks 02 Jun '10

02 Jun '10

Hi All, Thought I would let those that are interested know that I had success in running 24G on an Asus P6T with 24G kit of Kingston DDR3. While I was putting this together I saw lots of forum posts asking if anyone had tried it. Well we did here at our work and all looks great including running "memtest86" overnight. I have a fluid dynamics simulation running on it with 90% memory usage and all looks great.
