Two things to do :
1- run an ssh-agent that keeps your passphrase in memory, (works either in 
ssh1.5 or ssh2, but the configurations are - as far as I remember - 
different), in order to avoid the task of having to send connection 
authentication information ;
2 - configure, either in your .Mathematica/4.0/FrontEnd/init.m file, or via 
the Kernel/KernelConfiguration menu, the parameters to the remote kernel(s). 
Here is an example from my init.m file :

EvaluatorNames->{
  "Glarps"->{AppendNameToCellLabel->True},
  "GlarpsSecond"->{AppendNameToCellLabel->True},
  "Klumpf"->{RemoteMachine->True, TranslateReturns->True, \
AppendNameToCellLabel->True, MLOpenArguments->"-LinkMode Listen -LinkProtocol 
\
TCP -LinkOptions MLDontInteract", LoginScript->"ssh klumpf \"math\" -mathlink 
\
-LinkMode Connect -LinkProtocol TCP -LinkName \"`linkname`\""},
  }

In this example, the machine klumpf is on a local network, and declared in 
the /etc/hosts file.
