When trying to add a remote server, I get the following error message:
"Could not contact remote server: host key verification failed"
I have password-less ssh working from the web server (chem, a Sun) to the cluster (daito, Linux). Merely issuing from chem ...
ssh ssj@daito.cs
... logs me into daito.

My fields in Remote Server Manager are:
Server name: daito
Hostname: daito.cs (which is a Linux Cluster)
Cpu cores: 24
Username: ssj
Home Dir: /home/ssj
Scratch Dir: /home/ssj/tmp
Protocol: ssh

My fields in System Manager are:
Server name: chem (which is a Sun running Solaris)
CPU cores: 2
Registered User: Computational Chemistry
Login Message: Welcome to Calculations
System scratch dir: /export/home/webmo/tmp
Queuing system: "Built-in WebMO queue"
Authentication: "Built-in WebMO authentication"
Enable sudo usage: not selected
Store user jobs...: not selected

Note: in /~webmo/cgi-bin/interfaces/globals.int ...
scpOptions=""
scpPath="/bin/scp" (which is correct)
sshOptions=""
sshPath="/bin/ssh" (which is correct)

Please advise. Thanks. :-)

My problem was misunderstanding suexec. After considerable study and effort, I was able to configure suexec to run on the webserver. suexec allowed the script to run as me (as ssj or webmo). That, in turn, allowed password-less ssh to work through the script.
