Akibu,
It looks like the connection terminates immediately. We need to figure out
why.
If you run the exact ssh command as the backuppc user, do you get an error
or any output?
su backuppcUser
/usr/bin/ssh -q -x -l root akibu-desktop /usr/bin/rsync --server --sender
-svvvlHogDtprce.iLsf
If you don't see any output, hit ^D and you should get an error like this:
rsync: on remote machine: (null): unknown option
rsync error: syntax or usage error (code 1) at main.c(1634) [server=3.1.1]
[server] _exit_cleanup(code=1, file=main.c, line=1634): about to call
exit(1)
Next, are you sure that the directory /mnt/j/Favorites on akibu-desktop
exists?
Craig
