[rescue] SSH problem - Bad RSA1 key file

[Clif Smith]

I can ssh from a Solaris 9 system to one Solaris 8 system (without a 
password) running ssh v.1.0.  However, I can't ssh to another Solaris 8 
system, using the same keys, that's running ssh v1.2.30.  When I try, I 
see the following:
$ ssh -v system13
