Might be the RESTRING macro call on d->terminal_type while it's NULL. Not sure what you're doing, but if you use it "as is" you'd want to use: d->terminal_type = strdup("");

Should be more obvious if you execute:

telnet
set options
open nimud.divineright.org 5333

While using gdb it hung in select() instead of crashing.

This was already done as d->terminal_type = &str_empty[0];

You should use d->terminal_type = strdup(""); if you're gonna use the macro provided with mth.

This fixed the problem, and I am now using translate_telopts with no wierdness. Undefined Behavior beware.

So, please try connecting us to your network. Once connected I will release NiMUD with an announcement at the top of the README about contacting you should someone want to start a NiMUD and join your network.

The specific copy of NiMUD I run is at nimud.divineright.org 5333, but others may join your network someday.

Tintin was the first client I ever used, but I later switched to TinyFugue. Now I just use PuTTy. It would be interesting to see a "lite" version written for use with the standard telnet port instead of stdin, that was easily added to existing MUDs -- one with the ability only to connect with multiple sessions to a default mud address -- as a proxy service. That way MUD admins could set up Tintin on their primary port, with some default settings to auto connect to the MUD, plus the ability to allow players to manage multiple sessions with Tintin on MUDs (like mine) that allow multiplaying.

You know .. it could activate when another client isn't detected, otherwise merely forwarding to the port like tcpxd.

Locke

It's not working as of yet, I get:

RCVD IAC 0 0

Looks like it tries to send out the actual MSSP data, but it gets mangled somewhere.

The debug output in tintin is supposed to look something like the following:

The debug output in tintin is supposed to look something like the following:

There's that wierd character combination, ÿú !!! I have no idea but I will switch to your write_to_descriptor and see if that helps.

Are you related to 121.149.104.1 ? This bot seems to be repeatedly connecting, maybe it's your crawler?

I have done this. Please retry.

scandum · 03-23-2009, 03:48 PM

That's a korean IP, not sure who it is.

MSSP is still not working, nor is the mud announcing MSSP support.

I suggest you use tintin++ for debugging it with the following line to connect:

#config debug on;#ses x nimud.divineright.org 5333

If MSSP works you'll automatically get a formatted display of MSSP variables and values as I pasted earlier on.

Scandum,

No idea.

Back on topic:

3 more muds added MSSP bringing the total to 9.

I updated my crawler to report average players and average uptime.

MSSP Mud Crawler

And for those who missed the earlier mention, an easier to implement plaintext version of the protocol is described on the specification page.

MSSP (Mud Server Status Protocol)

locke · 04-25-2009, 07:00 AM

Still unable to figure out why it does not work with your network; it seems to be sending statistics to mudconnect's bot, though.
