I've had a couple of users mention this so thought I'd open an issue. The latest one said that their wifi disconnected, which dropped their BBS connection. When he tried to relog in the BBS said he was already connected. It seems the BBS didn't timeout his connection for quite a while.

This is probably going to be one of those random hard to pin down issues, but I thought I'd at least log it.

Using what protocol? If telnet, you can detect disconnected users more quickly by enabling the "Send Go-Aheads" feature.

Otherwise, you can TCP KEEPALIVE in ctrl/sockopts.ini to more quickly detect disconnected users. Or try tuning some of the TIMEO values in sockopts.ini. Your network stack may have configuration parameters for TCP session timeouts and liveliness checks that are via sock opts as well.

My user said, and I quote:

```
One problem I've been having is that when I go to certain screens, the BBS
seem to lock up. After a minute or so, I'll give up and disconnect. The problm then is, when I go to reconnect, it won't let me log in for hours because it believes I'm already logged in.
```

It wouldn't be so bad if it was 10 minute, 30 minutes or whatever, but I don't even see Linux having a socket timeout of hours. It's like it's not detecting he logged out at all. Maybe he only got back in because I did a recompile and shutdown and restarted.

I've asked him to notify me if it happens then I can check the state of the socket. When I have charged my laptop I can give it a try and see if I can replicate the issue by dropping wifi.

Set SCFG->Servers->Terminal Server->Max User Inactivity to some value?

I have the same problem and end up giving regular users the G exemption so that they can login to multiple nodes at the same time.

I’m going to try that on mine.

Would 10 mins be a suitable value? Why is it 1 hour for new users?

Thanks DM.

I set mine to 10 minutes. There's really no reason for a user to idle that long anyway.

Nelgin: what have you changed to 10 mins? The max user inactivity or max new user inactivity?

I have max login inactivity and max user inactivity set to 10 minutes and new user inactivity is 30. I'll probably change that to 10 also.
