• Telnet Connection Problem

    From Mike Dippel@3:640/1116 to ALL on Friday, February 11, 2022 15:47:06
    Lately, I am unable to connect to my BBS via Telnet from my home computer. I can,
    however, connect to it if I log onto one of my servers and telnet or http from that remote
    computer.

    I checked my log files and the home computer's IP address is not blocked. This is a
    recent occurrence although sometime in the past I could connect until I just lost the
    connection somehow.

    Is anyone else having a problem with telnet or http connections? Again, I can reach it
    from other computers, just not from my own. Maybe I can whitelist the IP address?

    I'm running version A47 I believe.

    In all these cases, are the computers all within your home network?

    Can you detail the topology a bit more?

    I have that issue too, at times. If I am trying to go to an address inside my own lan I will offten use 192.168.0.10 or whatever the address is. It won't work from the outside, but works from the inside.

    Maybe I can whitelist the IP address?

    You have to be able to reach the destination before a whitelist will do anything for you.

    I don't know what provider you have, but if you have Comcast, their cable modems have software which detect "threats" and will drop connections to any system considered a "threat."

    I triggered this by portscanning one of my own Digital Ocean droplets to make sure the Firewall was behaving properly. Then I lost connection with the droplet, although I could get it via tor, or in the method you describe.

    Note that, I was scanning the remote server *from* home -- the packets bouncing back to the port scanner were what tripped this "feature."

    I had to actually write to Comcast and tell them to knock it off. This is part of some new home security threat detection thing. I was able to reconnect in a few days. Comcast never wrote back; I don't know if the block expired naturally or they did something on their side.

    I mention it only because it was quite recently I found myself wrestling with this. It was irksome; I get why they think it's a good idea but probably like most here I don't want or need their help in this regard.

    If you're not using Comcast, well, forget everything I just said :)

    Make sure your gateway/router supports hairpinning https://en.wikipedia.org/wiki/Hairpinning

    If it doesn't, then you'll need to use your BBS's *private* IP address when inside your private network.

    Mike, not sure if youre using Mystic BBS or not but,
    Have you tried (in a shell) Mystic -l to log-in locally?

    I decided to add my home IP address to the whitelist, and I am now able to connect. Looks like the problem is solved. Yes, it was the home netowrk because I was able to connect with my phones network but not when I was connected to the WiFi.

    All seems well now.

    Yes, v47 It's working now after I put my IP address in the whitelist. The system runs on a remote server, so I can't log in locally. But, if I RDP into the server, local login works as well.

    Nice. Glad it worked out!

    If it's something that was working and then stopped, is your home computer using DHCP? Your lease may have expired, allocating you a fresh IP, which was not on your allow list for connecting.
