Connect two servers in shell script

Hello all, I know that is a question which has made too many times, and I have been looking into the threads but all posted was not sucessfully for me so...

I need a shell script which connect two unix servers, but NOT using ssh... Is there another way to do it?

I've tried ssh but it didn't work because the servers are Solaris 8 so, I don't think that is supported by SSH.

Please help, thanks.

telnet
