Correcting WLS Console Hang with SSH Node Manager Environment

I was having a frustrating situation yesterday where the WLS console would just hang after clicking the Servers link. Naturally I go to the Unix console to tail the logs and see what’s what, and these prompts for a password keep popping up. Entering the admin password is no help.

So I went to the next natural step of rebuilding the domain (the build is scripted, and yes, I backed up the domain first) and the problem is still there!

An email to a colleague more steeped in the dark arts of server administration than I results in the suggestion that this is due to a problem with SSH (the domain uses SSH Node Manager) and tells me test it with:

ssh username@hostname

to confirm connectivity and permissions.  What I get back is:




Permissions 0755 for '/app/home/username/.ssh/id_rsa' are too open.

It is required that your private key files are NOT accessible by others.

This private key will be ignored.

bad permissions: ignore key: /app/home/username/.ssh/id_rsa


With this new detail in mind, I went to an environment that was working, found it had the file permission set at 600, and preforming

chmod 600 /app/home/username/.ssh/id_rsa

Got me up and running again
