SSH not working - "pid 34138 (sshd), uid 0: exited on signal 4"



  • PFSense version 2.4.3-RELEASE (amd64)

    I'm needing a little guidance regarding one of my firewalls in the field when trying to access it via SSH via the lan interface.

    I've got it set up with a non-standard port, as well as disabled password access. I don't usually need SSH access, but I was doing some testing the other day and noticed that I could not connect to the firewall via SSH anymore. So I re-enabled the SSH password, and set the SSH port back to default, and I still could not access via SSH.

    On the client side I see: "Connection closed by <pfsense> port <port#>"

    In the pfsense logs I see: "pid 34138 (sshd), uid 0: exited on signal 4"

    Is there a way for me to get some more verbose output from the sshd process to track down what the issue is?
