The problem is very strange, my BackupPC machine is on a LAN behind a
Firewall/ADSL Gateway/DNS as 172.16.0.20.

On my BackupPC machine my resolve.conf have "nameserver 172.16.0.20" and
my machine work fine since over 3 years, I ping, ssh, apt-get, dig, all
reachable machines on Internet...

As soon I launch "/usr/share/BackupPC/bin/BackupPC_dump -v -f
mars.dyn.ac-fr.com" :

cmdSystemOrEval: about to system /bin/ping -c 1 mars.dyn.ac-fr.com
cmdSystemOrEval: finished: got output ping: unknown host
mars.dyn.ac-fr.com

Then I can't resolve any hostname anymore, "dig mars.dyn.ac-fr.com"
return nothing. The only thing that's fix is to ADD a public nameserver
outside my LAN in to resolve.conf on my BackupPC machine. Then
everything works fine.

I'm not sure that this problem is 100% endemic and I think BackupPC or
Perl have something to deal with but I don't know what.

I think you have to look this problem (BackupPC developers) I'm sure
other users will have the same problem someday.

I hope this help...

Thanks to Carl and all others on this list.

Sam.
