connectivity loss during idle
 
Hello. THis happens with Zmud as well and I'm wondering if it's not an issue with my network, but I wanted to see if anyone else was having this issue. If I am idle for an extended time, I lose connection. Sometimes, if I come back right on the threshold, it will hesitate for several seconds, then flood the screen with data. It's almost like it starts blocking information after a set time period. Has anyone else experienced this? I searched for an answer, but didn't find one. That, however, may just mean I used the wrong words, or did not see it. Thanks in advance for any help.

I have.
Sometimes I actually do get disconnected from the mud as well, but I get no indication till I try to send in a new command, the poof, the reconnect window pops up.

Yes. Or if I'm gone too long it tries to autoreconnect.

This is what happens when a router somewhere between you and the MUD drops your connection. It doesn't send any disconnect message back to Windows until you actually try to use the socket. This is the kind of issue that Rainchild (and others) have mentioned and is why I plan to add support for the socket Keepalive stuff to a future version. You don't notice this kind of behavior with web browsers because web browsers create a new socket connection for each page. MUD clients, like CMUD and zMUD, require a *persistent* socket connection, which is less reliable.

As more and more of the Internet gets used for email and web browsing, and less for telnet and other persistent socket apps, more and more ISPs are tuning their routers to drop inactive sessions. Also, many "home routers" that you buy for sharing a broadband connection have built-in timeout parameters that are enabled by default.

Zugg is 100% correct about the routers disconnecting after a timeout. My home broadband router disconnects me when I'm connected from somewhere else to a server at home. I get around it by setting up an alarm to do a carriage return every minute to keep me active, #ALARM *60 {#CR}

Is there a way to turn off this 'feature' in home routers?

I personally use a 90 second tick timer which sends 'backspace' to the MUD. I guess it depends on your host finding an unobtrusive command to send to it, some MUDs don't implement backspace correctly and it replaces it with a ^H which can make things a bit weird, however if the MUD does support backspace properly it's less obtrusive, you still have the connection alive but it doesn't spam you with a new prompt in the same way that a carriage return would.

#SENDP %char(8)

Will send a backspace.

Personally I just send a save every 9 mins. But then again I'm paranoid and don't trust the auto save features of most muds :)

I just use a return. One key to rule them all (or at least to reset the idle timers).

Saving isn't an issue for Simutronics, though. They back us up every hour, so even if the system fails they usually can get us close to the time of the crash.

Shalimar: It depends upon the router. Every router manufacturer has it's own admin interface. You'd have to consult the router documentation, or just go into the admin interface (usually via a web browser) and poke around looking for anything related to timeouts, or idle.

Problem is you don't know if it's your router... or the next one down the line, or the next etc.

And you can't check them all.
