Hy there,

I´m running a cron job under Suse 9.2 which gets some backups from a server. Sometimes it did not quite finish its jobs and after investing it a bit I found that the connections stalles. Can any one of you tell me the reason for this. Heres is the output of the run when it stalled:

Sink: T1152014498 0 1152014502 0

Killed by signal 2.

I used to start it with a limit of 1500 using the -l options. Any ides would be greatly appreciated, cause i don't want to rob all the bandwith from me coworker.

Can I see the script, or at least the scp related portion?

Also, what's your bandwidth like? Sometimes bad links can cause timeouts.

Thanks for taking on this problem, was givin up hope Ö)

Here is the part of me script where i start scp. $DATE is a directory on the server which contains about 12 zip files.

Code:

cd /../tach/auch/oder/so/sdfjklj123489s7dfn 2> /dev/null

while [ $? != 0 ]; do
  logger -i -p local3.info -t "backup" "SCP Download..."
  sudo -u backup scp -P 52022 -p -v -r *.*.*.*:/backup/$DATE* $SAVEDIR
  logger -i -p local3.info -t "backup" "Return $?"
done
