Starting backups from clients

Hello everybody,

i have a big problem in my UrBackup server (running on debian 7.2.0). I cant start backups from clients that are in another ip location (other domain). They shown as they are offline. I can start backups from clients in the same ip location like the urbackup server. The server ident key is the same on all clients. Whats the problem? :x

Can you reach them via other means, e.g. via “ping HOSTNAME” ?

No i cant ping all clients with “ping HOSTNAME”. I can only ping the clients in all IP locations with “ping 192.168.x.x”.

UrBackup probably uses the same hostname lookup as ping. So your DNS may not resolve Windows names.

I can’t fix this problem with this solution. Samba is already installed. If i try this: nmblookup -A 192.168.XX.62 in the same location i get the answer: Looking up status of 192.168.XX.62

If i try nmblookup -A 192.168.XX.50 in another subnet i No reply from 192.168.XX.50
