Hi NG,
I use amanda 5 years and now I have mystical problem.
My amanda server do backup from all my servers, PC's and notebooks
except self backup.
This happened few days ago.
After amcheck I see this message: 
planner: ERROR Request to asnserv1 failed: timeout waiting for ACK


In /tmp/amanda and /var/log/amanda have no files. 
Directories have modes:
drwx--S--- 2 backup disk     1024 Jun 18 01:37 /tmp/amanda/
drwxrwx--- 4 backup backup  12288 Jun 10 09:28 /var/log/amanda/
drwx--S--- 2 backup backup  45056 Jun 10 09:37 /var/log/amanda/amandad/

In /etc/services I have:
amanda          10080/tcp                       # amanda backup services
amanda          10080/udp
....
kamanda         10081/tcp                       # amanda backup services
kamanda         10081/udp
amandaidx       10082/tcp                       # amanda backup services
amidxtape       10083/tcp                       # amanda backup services

amanda.conf work for all computers except amanda server asnserv1.

Thanks for help,

Leonid
