Zimbra help?
by ML 04 Nov '09

04 Nov '09

Hi All, Is anyone versed in Zimbra? I have most things working except some MTA issue. I tried posting on the Zimbra forums after reading the docs, but my post was labeled as SPAM and the moderators have not replied to my private message to get my post reviewed. Who uses this type of method for getting help anyway? Aren't the days of Bulletin Board BBS's gone? Anyway... I installed ZCS for the first time today. Most things are running except I cannot send or receive mail. I get MTA errors. I assume that it is not running. When I send I get unable to connect to MTA. How do I diagnose the issue? in /var/log/zimbra.log: Nov 2 17:57:28 indie postfix/postfix-script[9282]: warning: not owned by root: /opt/zimbra/data/postfix/spool Nov 2 17:57:28 indie postfix/postfix-script[9289]: warning: not owned by root: /opt/zimbra/postfix-2.6.5.2z/conf/main.cf Nov 2 17:57:28 indie postfix/postfix-script[9290]: warning: not owned by root: /opt/zimbra/postfix-2.6.5.2z/conf/master.cf Nov 2 17:57:28 indie postfix/postfix-script[9291]: warning: not owned by root: /opt/zimbra/postfix-2.6.5.2z/conf/master.cf.in Nov 2 17:57:28 indie postfix/postfix-script[9294]: warning: not owned by postfix: /opt/zimbra/data/postfix/./spool/maildrop/E18EC1C1048D Nov 2 17:57:28 indie postfix/postfix-script[9295]: warning: not owned by postfix: /opt/zimbra/data/postfix/./spool/pid/master.pid Nov 2 17:57:28 indie postfix/postfix-script[9308]: starting the Postfix mail system Nov 2 17:57:28 indie postfix/master[9309]: fatal: bind 0.0.0.0 port 25: Address already in use Nov 2 17:57:28 indie saslauthd[9316]: detach_tty : master pid is: 9316 Nov 2 17:57:28 indie saslauthd[9316]: ipc_init : listening on socket: /opt/zimbra/cyrus-sasl-2.1.23.3z/state/mux Nov 2 17:57:28 indie zimbramon[2574]: 2574:info: Starting stats via zmcontrol Nov 2 17:57:59 indie zmmailboxdmgr[10822]: status requested Nov 2 17:57:59 indie zmmailboxdmgr[10822]: status OK Nov 2 17:57:59 indie zmmailboxdmgr[10894]: status requested Nov 2 17:57:59 indie zmmailboxdmgr[10894]: status OK Nov 3 01:58:00 indie postfix/postqueue[10943]: fatal: Queue report unavailable - mail system is down Nov 2 17:58:09 indie zmmailboxdmgr[11484]: status requested Nov 2 17:58:09 indie zmmailboxdmgr[11484]: status OK I have not done anything with Postfix at all....U am sure it is the Fatal Bind message above, do I need to configure Postfix?

NTFS and elrepo
by Ron Loftin 04 Nov '09

04 Nov '09

I have here a box which I dual-boot between CentOS 5.4 and an older version of that "other OS" that I'm using to check out the ELrepo version of kmod-ntfs. After installing as per the directions on the ELrepo site, I can mount an NTFS filesystem, and when I type "mount" with no options the output tells me that the target filesystem is mounted read-write. However, when I try to create a file on that filesystem as root, I get a "Permission denied" error, which leads me to think that I'm missing something here. So far, Google has not been very helpful here, so if anyone can shine some light on this, it would be welcome. -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?"

rpm and yum issues
by Monty Shinn 04 Nov '09

04 Nov '09

Greetings. I am having issues with rpm/yum on a centos 5.2 x86_64. I am trying to update from 5.2 to 5.4. During yum update, the application became unresponsive during the package search. It had not begun to download any packages. I tried to do a "yum clean all", but that wouldn't complete either. I tried to do a rpm --rebuild, but that failed with a segmentation fault. Tried it a couple of times... Reboot didn't work. I copied the database files out of /var/lib/rpm to a safe location, then deleted the __db.* files. Ran rpm --initdb. That seemed to work. Now, I've been running rpm --rebuild for around 18 hours. The load factor on the server is 1.0, according to uptime. Top shows that it is running, using 100% cpu. Iostat shows around 25% usr load. I see the os raid drives bounce on occasion. ps -ef shows the following daemons running (applicable to rpm): /usr/lib/rpm/rpmd --rebuilddb /usr/lib/rpm/rpmq -q --all --qf %{name}-%{version}-%{release}.%{arch}.rpm\n /bin/sort A search of google led to no real help, but I may be searching wrong... Here are the specs: Centos 5.2 kernel: 2.6.18-92.1.6.el5 #1 SMP x86_64 2 xeon 3.20ghz procs, 4 logical I can't get the rpm or yum version, since rpm is still running. This is a stock install, using the xfs kmod. Only non-standard app installed is the 3ware utilities. I have run a yum update on another 64bit box (almost identical hardware) and a 32 bit box with no problems. The boxes were at 5.2 and 5.0, respectively. Any thoughts? Thanks, Monty

bind segfault in conjunction with dbus - what to change?
by Brian Schueler 04 Nov '09

04 Nov '09

Hi all, I have a problem running bind on C5.4 when the messagebus service is activated. When I switch off the dbus message service bind runs well. With dbus activated bind crashes with a segfault. How can I get rid of this error? What shall I change? SElinux (the source of most unexpedted things) is switched off. Following versions are installed: bind-9.3.6-4.P1.el5 bind-libs-9.3.6-4.P1.el5 dbus-1.1.2-12.el5 Thanks, Brian. starting the bind causes following error: [root@t41 ~]# /usr/sbin/named -u named -D -t /var/named/chroot -g 04-Nov-2009 16:58:14.905 starting BIND 9.3.6-P1-RedHat-9.3.6-4.P1.el5 -u named - D -t /var/named/chroot -g 04-Nov-2009 16:58:14.906 adjusted limit on open files from 1024 to 1048576 04-Nov-2009 16:58:14.907 found 1 CPU, using 1 worker thread 04-Nov-2009 16:58:14.907 using up to 4096 sockets 04-Nov-2009 16:58:14.943 loading configuration from '/etc/named.conf' 04-Nov-2009 16:58:14.956 using default UDP/IPv4 port range: [1024, 65535] 04-Nov-2009 16:58:14.962 using default UDP/IPv6 port range: [1024, 65535] 04-Nov-2009 16:58:14.978 listening on IPv4 interface lo, 127.0.0.1#53 04-Nov-2009 16:58:14.985 /etc/named.conf:58: using specific query-source port su ppresses port randomization and can be insecure. 04-Nov-2009 16:58:14.990 command channel listening on 127.0.0.1#953 04-Nov-2009 16:58:14.997 ignoring config file logging statement due to -g option 04-Nov-2009 16:58:15.005 zone 0.in-addr.arpa/IN: loaded serial 42 04-Nov-2009 16:58:15.008 zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700 04-Nov-2009 16:58:15.010 zone 255.in-addr.arpa/IN: loaded serial 42 04-Nov-2009 16:58:15.018 zone 0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0. 0.0.0.0.0.0.ip6.arpa/IN: loaded serial 1997022700 04-Nov-2009 16:58:15.023 zone localdomain/IN: loaded serial 42 04-Nov-2009 16:58:15.026 zone localhost/IN: loaded serial 42 process 13548: arguments to dbus_connection_unref() were incorrect, assertion "c onnection->generation == _dbus_current_generation" failed in file dbus-connectio n.c line 2615.

yum clean all - adverse effects?

Are there any adverse effects to "yum clean all"? Does the system lose its memory of what is installed/updated?

grub problems
by m.roth＠5-cent.us 04 Nov '09

04 Nov '09

This is irritating: I've got a server I just upgraded to 5.4, then rebooted, only to discover that it just *sits* there at the grub boot menu. I looked at grub.conf, and uncommented hiddenmenu (which should have been done long ago). It *still* sits there when I reboot. Any clues, folks? mark grub.conf: #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-164.2.1.el5) root (hd0,0) kernel /vmlinuz-2.6.18-164.2.1.el5 ro root=LABEL=/ rhgb initrd /initrd-2.6.18-164.2.1.el5.img title CentOS (2.6.18-164.el5) root (hd0,0) kernel /vmlinuz-2.6.18-164.el5 ro root=LABEL=/ rhgb initrd /initrd-2.6.18-164.el5.img <snip>

problem installing CentOS 5.3
by Buz Davis 04 Nov '09

04 Nov '09

First, let me apologize to Akemi Yagi for my delay in answering his last query. After failing with 4.8 I realized that I had at least one and possibly two computers capable of handling 5.3 (one was newly purchased second-hand and had many unknowns about it. The other was well documented but its power was obscured by a thick layer of Windows XP). To answer Akemi's last questions, yes, I am sure that the disks were all 4.8. I checked with md5sum before burning the cds and am not sure how to check further than that. I never got past using the first (modified) disk that I downloaded from the url you gave me, because anaconda failed to find a file - having to do with GNOME, so the process aborted. Again I apologize for delaying my response, but I have been occupied again with 5.3, but on the newer computers. 5.3 installed easily and correctly on the first machine (celeron, 1.2Ghz, 512M ram, 80G disk). With the second machine I am getting consistent failure to load X, despite many attempts that appeared to be good installs. For the last attempt I had about 160G of disk available, over 800M of ran, and (as reported by the BIOS, a pentium 3 processor. Unfortunately a remaining big unknown for that system is the Mhz rating for the processor. When I got it, with a broken XP system on it, it was set at 550Mhz. The BIOS allows three choices: 366, 500, and 7xx (I don't remember the last value precisely, but the system wont boot at all, so it's moot). I have mainly messed with the 550 setting, but have occasionally tried at 360. It doesn't seem to make a difference. On that system the output of uname -a gives 2.6.18-128.3l5 for the kernel, and "i686 i686 i386" at the end. Free shows 905240 total and 231688 used. Console mouse services work. When I attempt to load X I get the hollow-x cursor, then the black screen with the nautilus window and then white bars at top and bottom, along with an arrow cursor. The white bars get populated with some icons and then comes the blue screen with the doily-like design, but at that point the system appears to be hung. The computer, home, and trash icons do not appear on the desktop, nor does a mouse-pointer, and wiggling the mouse does nothing. I have compared the /var/log/Xorg.0.log files from the two machines (one that works, one that doesn't), and they both end in the same place: <snip> (--) <default pointer>: PnP-detected protocol: "ExplorerPS/2" (II) <default pointer>: ps2EnableDataReporting: succeeded <eof> I would appreciate any help in getting X to work on this second computer Thanks, Buz Davis
