If you want to supply additional command line arguments to the ssh command when it runs on a specific Host, you can supply those arguments in the Advanced Parameters field for that Host. The syntax of the parameter in the Advanced Parameters field is as follows:
sshargs=-option|-option |
option is the command line option that you want supplied to the ssh command. Add more than one option by separating the options with a |.
If you want the ssh command to enable authentication agent forwarding, supply the -A option in the Advanced Parameters field:
sshargs=-o|BatchMode yes|-A |
