David's questions

Attempting to run XMing, the remote host is Ubuntu, going through Putty. Have spent hours carefully double-checking all settings, reviewing XMing's troubleshooting guide, etc. Rather than continuing this path, I want to use a tracing tool or sshd logging to somehow identify exactly why I'm getting the "can't open display" error. This occurs when I test by runningxclock or firefox.

I've turned off firewalls on each computer.

One thing that bothers me: in Putty I'm setting the X display location to localhost:0, which they say sets the DISPLAY variable on the remote host. But after logging in through Putty, I do an echo $DISPLAY and it shows nothing. Shouldn't it return localhost:0?

What tools or logs or other approach could I use to figure out what's wrong?

I'm setting up Rundeck for the first time. I'm testing by configuring a node with username="david". I've set ssh-password-storage-path="keys/foo/david" which is where I've uploaded the private keyfile in rundeck. I've tested that I can manually log in as david to the remote machine using passwordless login, with my public key in the remote machine's .ssh directory.

It seems as though this should work on rundeck, that it would attempt to connect to the remote machine as 'david' since that's the username configuration in the node definition. Do I understand that correctly?

But I'm getting the following error in the rundeck.log file:

Node failures: {remote-machine-name=[ConfigurationFailure: SSH keyfile does not exist: /var/lib/rundeck/.ssh/id_rsa]}...

Is this error referring to a path on the remote machine or the rundeck machine? And why would it even be looking for an id_rsa file when I've already told rundeck that it should be looking for the private key (id_rsa) in the key storageJabra Mic?

Thanks!
