Thanks Craig,
it was just a problem of permissions on ping. I've switched them to
normal but something was still turning them back so I've done some
checking in cron and found what was turning permissions on /bin/ping
back to the default (ie: setuid root). It was a scipt named msec
that's run every minute by cron. It's a security feature in MDK 10.0
(and RedHat I think) that keep file/directory permissions up-to-date
following a special file (perm.4). I've modified it and everything
is fine now.
Thaks for this wonderful program.

I'm running the 2.1.0 version on MDK 10.0 and I have a little problem
with permissions I think. Here is the result from the FAQ test for
finding a host :
[backuppc < at > queribus /]$ /opt/BackupPC/bin/BackupPC dump -v -f amandine
Name server doesn't know about amandine; trying NetBios
cmdSystemOrEval: about to system /usr/bin/nmblookup amandine
cmdSystemOrEval: finished: got output querying amandine on 192.168.0.255
192.168.0.1 amandine<00>
NetBiosHostIPFind: found IP address 192.168.0.1 for host amandine
cmdSystemOrEval: about to system /bin/ping -c 1 192.168.0.1
cmdSystemOrEval: finished: got output ping: icmp open socket: Operation not permitted
CheckHostAlive: first ping failed (512, ) no ping response
ping: icmp open socket: Operation not permitted
I've tried the ping -c 1 192.168.0.1 as root and it worked, so do you
know what group permissions do I have to add to the "backuppc" user so
he can do a ping ? Or is it something else?

CB> $Conf{PingCmd} = '/bin/true';
