Timbuktu "Secure" Connection and Certificates?

[Trevor, Rob]Rob Trevor - 08:04am Sep 1, 2005 PST

Does anyone have any suggestions on how to use the Secure option in Timbuktu when the target machine has "PasswordAuthentication no" in /etc/sshd_config?

I regularly use SSH to connect the two machines - but I can't get Timbuktu to connect with the secure option since it tries to use SSH via user/password rather than the security certificates installed for SSH on the two machines.

How do I get Timbuktu to use SSH with certificates rather than passwords? (Well, I guess I can build a tunnel first, say using SSH Tunnel Manager, but it would be a lot easier if the existing Timbuktu interface could do it.)

Needless to say Timbuktu tech support just pointed me to the standard "how to use" document which implicitly assumes that the target machine has "PasswordAuthentication yes" in /etc/sshd_config.

Andrew (and Mike)

A very belated thanks. (It has been a mad month and I wanted time to confirm my intial testing.)

Unfortunately, it just doesn't work for me. I can SSH using cert's into my other Mac's. I can connect to them using Timbuktu. But I can't connect using Timbuktu's secure connection. (I've tried Panther->Panther, Panther->Tiger and Panther->Jaguar.)

All I can assume is that Timbuktu is making quite a few more assumptions about the SSH connection parameters (in addition to the one you have disclosed re same user id and password).

Perhaps you might be able to suggest to Mike that Timbuktu should read the ~.ssh/config file on the client or (better yet) have its own (optional) SSH config file on BOTH the client and server????

Many thanks

Rob
