Hi All,

I have two solaris machines. One of them has a backup drive attached to it, and I take backup of the other machine using ufsdump like this:
ufsdump 0ucf 111.111.111.111:/dev/rmt/0n /
And on the remote host, I've allowed my host to connect without a password in the .rhosts file. Which is not secure.

How can I do this implementation using SSH? I think using scp, but i'm not aware of the details.

Thanks.

P.S. Do you already have ssh set up to work without passwords?

I think the direct ssh replacement for your existing command would be:
ufsdump 0ucf - / | ssh 111.111.111.111 "dd of=/dev/rmt/0n"

Use:

ufsdump 0ucf - / | ssh root@111.111.111.111 "dd of=/dev/rmt/0n"

you might endup have to use "dd of=/dev/rmt/0n obs=128b", it depands on your
network connetions.

Thank you both.
Now, I come to an interesting question. How can I set up ssh to work without passwords? Do I install my key at the remote server's trusted keys?
