postfix problem since update: mail loops back to myself
by thorsten 23 Sep '06

23 Sep '06

Hello I already asked in the IRC, but apart from recommendations reading the mailing lists, nobody could help me. I read all postfix-update related articles but non of them seemed to match or resolve my problem: Everything works fine, apart from one host, which we are doing MX backups for (backupdomain.com) Sep 22 12:18:58 homer postfix/smtp[18784]: 6BD7B1189E4: to=<user(a)backupdomain.com>, relay=none, delay=53, status=bounced (mail for backupdomain.com loops back to myself) Sep 22 12:18:58 homer postfix/cleanup[18791]: B3DD6118A13: message-id=<20060922111858.B3DD6118A13(a)mail.mydomain.com> Sep 22 12:18:58 homer postfix/qmgr[18776]: B3DD6118A13: from=<>, size=2758, nrcpt=1 (queue active) Sep 22 12:18:58 homer postfix/qmgr[18776]: 6BD7B1189E4: removed The backup MX in our domain record for the backupdomain has priority 20, we 10. dig MX mydomain.com mydomain.com. 86400 IN MX 20 mail.backupdomain.com. mydomain.com. 86400 IN MX 10 mail.mydomain.com. postfix's transport_map is configured to use mysql. a postmap -q backupdomain.com mysql:/etc/postfix/sql/transport returns: smtp:mail.backupdomain.com so it was forwarding a message to that domain. That worked fine. After the postfix upgrade, this stopped working. The target the error, I removed the smtp:mail.backupdomain.com entry from the mysql table and also removed the MX entry for the backupdomain, which I was told, could cause problems as well. It still says: mail for backupdomain.com loops back to myself. So, I am wondering, where postfix gets this information from? Can you give me some further advise? thx, thorsten.

EXT3-fs error (device dm-4): ext3_add_entry: bad entry in directory #14370410: rec_len % 4 != 0 - offset=0, inode=1309281588, rec_len=16761, name_len=78 Aborting journal on device dm-4. ext3_abort called.

I was actually referring to the SATA cables. I guess my reply got a bit garbled there. One topic at a time... :) I take your point regarding the power supply cables. I'll put the drives on separate legs and see what happens. -- Bowie

I'll give it a try. I tried smartctl and it ran fine, but found no errors (on the short test). FYI - I had to specify the ata device type to make it work. smartctl -d ata -t short /dev/sda I was also able to get the smartd service running by adding '-d ata' to both lines in the /etc/smartd.conf file. Everything seems to be running normally now. Smartd is configured to send me email on problems now, so I'll keep an eye on it and see what happens. -- Bowie

Firewire question (Centos 4.4)
by Akemi Yagi 22 Sep '06

22 Sep '06

Johnny Hughes wrote: > > Firewire is not turned on in the standard RHEL kernel. It is on in the > CentOSPlus kernel. Since firewire is a must have for the system I am setting up, I recompiled the kernel with the firewire support turned on and installed it. Then later, I decided to try the CentOSplus kernel. The system booted just fine but I noticed something odd. In /boot, System.map and vmlinuz are still pointing to the custom kernel, not the centosplus kernel. Should I manually correct the symlinks?

Is it possible that bind has also been updated at the same time. Where does your resolver on the mail server think the backup domain is? Also, did your /etc/hosts file change in the upgrade or subsequent to that? Just a guess, alex

Tyan K8HM and lm_sensors
by Bowie Bailey 22 Sep '06

22 Sep '06

I have a Tyan Thunder K8HM (S3892) motherboard and I am trying to get lm_sensors to work with it. The problem is that I am getting conflicting information. The source for lm_sensors says not to compile the modules for the 2.6 kernel. The information from Tyan says that I need to compile the modules if my kernel is less than 2.6.12. Has anyone here configured lm_sensors for this motherboard? Any suggestions on whether it is safe to install the lm_sensors i2c-piix4 module in the 2.6.9 kernel? CentOS-4.4-x86_64 lm_sensors 2.10.0 -- Bowie

Problem deleting an active route
by Dale 22 Sep '06

22 Sep '06

Hi all, Some how I have an extra active route setup in my CentOS 4.4 system (that unfortunately at a data center a ways away from me). I have tried using /sbin/route del -net xxx.xxx.xxx.xxx but get an error. I also have Webmin installed and I can delete the route from there, but on applying the network config, the route comes back. I have no idea where it is coming from. It is preventing me from getting out of the box to any other services. Any suggestions greatfully accepted! Thanks Dale
