| Subject: | ssh-rsa problem |
this relates to a previous post on the same subject.
I'm trying to run cmd.pl
I tried to install through cpan using SSH2 alone and SSH1 and SSH2 (option 3), but it didn't help.
I paste the output of the error I get from two trials below.
I'm using perl v5.8.0 on a redhat 9, kernel 2.4.20-27.9
my .ssh/known_host looks something like this:
b2,192.168.0.2 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAuCS4gV54C1H8+ke1Ln249K07P0Iyfn8l41gReEIQ1HhM7jHI4+URwPVrIZdQfUXhVHzNMzcPLfaED68bglZ5aVry+e+skJWreWAj2z9YooYqyogP4CgyYn3N5AsvNdB0T3THpPSAKlZrmBgPexwvamsdrZS/BBJcc0sAAbCLSY8=

Here is the configuration of my network, in case there is a correlation with the errors I obtain (prototype Beowulf Cluster setup)
I'm trying to run the script from the b1 host to access the b2 and b3, which both have the .ssh/id_rsa.pub of the b1 host saved in their .ssh/authorized_keys (and /etc/passwd /etc/group /etc/shadow /etc/gshadow from b1 have been ported to b2 and b3) so that all machines have the same passwd and I can connect from b1 to b2 and b3 with no passwd, by just issuing:
ssh b2 or ssh b3 (b1 and b2 full host names are in /etc/hosts of b1).
NFS is running on all boxes so that /home on b1 is mounted on b2 and b3.
Thank you for any help you could provide.
Aloha,
