Hello Quin,

I use option a (as in auto-size) with my travan. works like a charm:

dump 0dua /dev/nrst0 /


Maybe you could help me in return? I'm running 2.2-stable with the
default login.conf file. This prevents root from doing rsh (and rdump).
How do I set up a login.conf that doesn't prevent rdump? This
compromises security, I know. How bad is this for security, though?

Regards,
Palle
