Troubleshooting Steps

Troubleshooting steps for typical service startup and connection issues:

• Server side: run sshd in debug mode
  • Stop-Service sshd (if sshd service is running)
  • Open cmd as SYSTEM. Download psexec from here.
    • psexec -s cmd
  • sshd.exe -d
  • This will dump debug logs in real time to stdout on the console
  • You can also add additional ds for more detailed loggin:
    • sshd.exe -dd or sshd.exe -ddd
• Client side: start ssh in verbose mode
  • ssh.exe -v ...
  • This will dump verbose logs in real time to stdout on the console
  • You can also add additional vs to get more verbose messages:
    • ssh.exe -vv ... or ssh.exe -vvv

Troubleshooting more complex issues:

• Server side
  • Stop sshd
    • Stop-Service sshd
  • Delete sshd.log and ssh-agent.log (in the logs directory of your installation path)
  • Set LogLevel to DEBUG (or DEBUG2/DEBUG3 for higher levels of logging) in sshd_config
  • Rerun the workflow that's giving you problems. logs\sshd.log will contain sshd related traces.
  • If the problem isn't clear, please post these logs along with some steps to help us reproduce your problem in our GitHub Issues.
• Client side
  • Set LogLevel to DEBUG (or DEBUG2/DEBUG3 for higher levels of logging) in ssh_config.
  • Run ssh.exe in verbose mode as detailed above
