It worked pretty well from over here. I saw what I was typing before
hitting enter. It didn't echo to me what I had said after I typed
enter, but I could tell by what people were saying to me that they
could see what I had typed. It told me everyone else's port number,
but didn't tell me what my own port number was, although I was able to
figure that out when people referred to me by number.

Re: [BLUG] The Hub raw chat over telnet/netcat

Well sorry folks, its just not working as well as I hoped. I need to
get rid of the buffering issues. But it was a good experiment prior to
the networking presentation.

Re: [BLUG] The Hub raw chat over telnet/netcat

I read the page.

My understanding is that there are both block and line methods to
communicate via the Telnet protocol. Normal telnet sessions use
character mode, but MU*s and talkers normally use line-mode.

It looks like the hub was written with a character/block bias, and
you're trying to use it in a line-mode way.

What we're seeing is that it appears to be doing character-based
buffering of whole blocks with no regard to lines.

Re: [BLUG] The Hub raw chat over telnet/netcat

There are some buffering issues. The code is from 2001 and it is
fairly basic:

https://lopsa.org/node/1351

I modified it to show what port was talking. I may have screwed
something up. I started it again with a larger buffer, maybe that will
help. That was the first try though with multiple people on it.

Re: [BLUG] The Hub raw chat over telnet/netcat

Weird thing. Doesn't seem to provide immediate feedback when you type.

I keep 'tf' installed, so I tried connecting via that. (TinyFugue, a MU*
client) When I got no immediate feedback I gave up.

[BLUG] The Hub raw chat over telnet/netcat

telnet suso.suso.org 20202

Or you can use netcat:

nc suso.suso.org 20202

Kinda interesting. Basically, very poor man's IRC. I modified a
snippet of code called hub.c to do it, making it more efficient and to
show port numbers (0-100) when someone talks.
