      I keep getting broken pipe when ssh into pfSense on my LAN. It began after I upgraded OS from Kubuntu 16.04 to 18.04 when I was still on pfSense 2.4.3-release p1. While on 16.04, I could remain logged in all day. Yes, I have experimented with settings on my /etc/.ssh/config as well as /etc/ssh/sshd_config on pfsense.

      Last week I upgraded to pfSense 2.4.4 and noted that the issue disappeared only to reappear today. These are my ssh settings:

      /etc/.ssh/config
      Host *
      # TCPKeepAlive yes (makes no difference)
      ServerAliveInterval 120
      ServerAliveCountMax 720

      pfSense
      /etc/ssh/sshd_config (all other default settings omitted)
      ClientAliveInterval 120
      ClientAliveCountMax 720

      I tried configuring ssh with id_rsa.pub but this didn't help either.

      I should add that I'm typically running tcpdump while ssh. Usually I am monitoringt DNS on port 853 or for pfBlockerNG activity.

      I appreciate any help.

      Forgot to add, that I can ssh into other systems and remain logged in for the entire day without getting the broken pipe. Broken pipe ONLY happens ssh to pfSense.
