Hello to everybody.
First of all, excuse my english, i'm a french user.
Our compagny use amanda to make backup of approximalty 400 servers.
When amanda job start, it make two DNS query: a "hostname" and a "reverse".
Since now 2 month, everyday we have some hosts that have not been backuped by
amanda because the DNS query had failed. Hosts are never the sames, and the
query failed on direct or reverse query.
I have mirrored the switch port where my dns server is pluggued, and i have
captured all packets and what i see is:
- amanda query is captured
- DNS server don't answer to this query
I have put "severity debug 9" on all named channel logging and i do not see
any kind of error in logs.
So my question:
- Can bind "miss" or "refuse" some query because of "overload?" and if yes,
can we log that?
- bind 9.2.4 RC2, chrooted
- Linux 2.4.20-13.7custom #3 SMP (BI PIII 500Mhz, 1Go RAM)
- Red Hat Linux release 7.2 (Enigma)
