I have installed ISPCONFIG last year, everything has been working properly until one day I got a message that Clamav is OUT of date. Since then my machine slowed down and all the mails were rejected. I uninstall clamav and installed the latest version and everything went fine again. The same problem happened today but this time I keep getting this message delayed SMTP module(domain xx.com) reports: mail.xxx.com: connection refused Can anybody help?
from the mail.err log, the following was displayed: Apr 23 16:42:08 mirror courierpop3login: authentication error: Input/output error Apr 23 17:06:30 mirror postfix/bounce[19173]: fatal: lock file bounce E7F7D379B9C: Resource temporarily unavailable From the mail.info Apr 23 17:06:30 mirror postfix/bounce[19173]: fatal: lock file bounce E7F7D379B9C: Resource temporarily unavailable Apr 23 17:07:12 mirror postfix/bounce[19145]: fatal: lock file bounce 452D9379BA5: Resource temporarily unavailable from clamav: ERROR: getpatch: Can't download daily-9243.cdiff from db.local.clamav.net Ignoring mirror 130.59.10.36 (too often connections with outdated version) Ignoring mirror 193.1.193.64 (too often connections with outdated version) ERROR: getpatch: Can't download daily-9243.cdiff from db.local.clamav.net WARNING: Incremental update failed, trying to download daily.cvd When I rebooted the server it freezed after load ISPCONFIG. What do I do to make it go beyond this?
I also ran a netstat -tap got this as answer tcp6 ....op3 ..... TIME_WAIT When I run telnet localhost 25, it works then when I do ehlo localhost, I get timeout exceeded. The server has become very slow to work with. It takes about 1 minute to display only one letter that I typed. Can anybody please help?
when doing netstat -tap I also see sth like smtp cenmail2.ceridia 56746 ... listen there are other ip addresses that I do not know. How do I delete them and block them from using my smtp to spoof my mail server?
I'd reboot the server and then use rkhunter and/or chkrootkit to check if there's malware installed on the system.
