Hi,

I installed ReaR (Relax and Recover 1.12.0, from distribution package
(SLES 11SP1)) recently onto a machine, running some Database
stuff and should be fast and easily to recover. 
Everything works fine so far, but lately we tried to test the recovery
media and found that the network is not configured.
Since the Backup now lurks on NFS this is not what i hoped expect.

seems to be ok.
But I still have no network to start recovery. Is this known and maybe
someone got this to work properly?
Has anyone any idea what went wrong?
