  • Telnet TCP4 port shutting down randomly

    From Dredster@1:103/705 to All on Friday, August 04, 2023 20:36:59
    I've got some odd behavior going on that I'm having fits trying to iron down.

    I'm running Synchro on FreeBSD 13.x and the server will start fine.. but after a bit, the listener on port 23 shuts down. Its only for tcp4 though and the tcp6 port is still running. I don't have telnet enabled on the base os, and can't find anything in conflict with the port. It's just dead.. Anyone else ever seen this? I can understand if another process is attempting to run but the logs show that Synchronet can't bind to the port, yet nothings running on it to prevent it that I can see..

    What does 'netstat -ln | grep :23' report when this happens?

    I'll have to look again, it's not done it today.. but when I noticed it, sbbs had the tcp6 port but nothing running on tcp4 port 23.

    Yea, ipfw is running and I've added an allow for port 23. So far, it's not done it again..
