Putty - Diagnose Connection Errors Via Event Log

SUMMARY: Use PuTTY's event log to help diagnose errors when connecting to remote computers.

Are you having difficulty connecting to a particular client system via PuTTY? You can use the Event Log to view information about the current terminal session such as:

* Encryption algorithms initialized
* Host key fingerprint
* If a shell or command was started
* Password sent
* Remote SSH server version
* Whether access to remote was granted

Reading this event log might help determine if a password was delivered, if a remote server is using an old or buggy SSH server, and whether access was granted but the session terminated due to a problem in opening the remote command shell.

1. Right-click on the PuTTY session window's title bar.

2. Select "Event Log".

3. The "PuTTY Event Log" dialog box appears. You can scroll through the diagnostic information and/or click the "Copy" button to copy the information to the Clipboard.

4. Click "Close" when you are ready to close the event log.
