Re: [BackupPC-users] ping too slow (using ssh over internet)

[<rom...@va...>]

Ok, thanks a lot for your answer.
I'll try it this afternoon.
I had to check this file.  ;-)

Thanks again.
Have a nice day.

It is not necessary to have a ping response under 20msec and when you
connect to your backuppc-server via a tunnel through the internet you
will not get this response times :-)

In order to change the time after a ping is called "to slow" you can
edit the /etc/backuppc/config.pl

$Conf{PingMaxMsec} = 200;

Maximum round-trip ping time in milliseconds. This threshold is set to
avoid backing up PCs that are remotely connected through WAN or dialup
connections. The output from ping -s (assuming it is supported on your
system) is used to check the round-trip packet time. On your local LAN
round-trip times should be much less than 20msec. On most WAN or dialup
connections the round-trip time will be typically more than 20msec. Tune
if necessary.
