gsh - Global Shell: Where do you put the shared keys, password?

Question

I'm trying to use the gsh command on ubuntu to do some embarrassingly parallel stuff. I've made an /etc/ghosts file containing all the IP addresses for the hosts, and each host has an account that I created just for "cluster" purposes.

However, when I try a command such as,

$ gsh -l cluster ok 'echo $host'

I get in return two errors,

hostn: Host key verification failed.

hostn+1: Permission denied (publickey,password,keyboard-interactive)

I've already SSH'ed these computers and exchanged keys. I can't find anything in the gsh man page about a key file. Also, there is the question of where to put the password.

This is the version that I am using: http://outflux.net/software/pkgs/gsh/

If you can't answer, then maybe you can suggest an alternative.

Answer 1

It looks like gsh uses ssh. Therefore, you'll need to set up your authorized_keys file as explained in OpenSSH Public Key Authentication.
