I wanted to hop onto a MUSH and check my +mail from work. At home, I connect with no difficulties, but when I attempt to connect from work, the connection continually times out with the error message:

Unable to connect to "Chronicles", code = 10060 (Connection timed out)
Error occurred during phase: Connecting to world: 216.136.9.8, port 8810

I ran a ping, and 4 packets were sent and 4 packets were received with an average round trip of 26ms.

I ran a tracert, and it ran 12 traces. The first two went through in <1ms, the next 9 timed out, and the last went through in 26 ms.

I thought maybe it's some kind of firewall issue, but I'm not certain, given that the connection is not being refused, it's just timing out.

Any thoughts?

Might be a firewall blocking any telnet connections. I know my college does that.

Can you connect using telnet at all?

Connection is refused when the other end sends a NAK (negative acknowlegement), however a timeout is when no response is received (neither positive nor negative).

It is certainly possible for the firewall to block in such a way that the NAK is not received, giving the symptoms you describe.

Ping and tracert use a different protocol (ICMP) and the fact that they work, or not, does not necessarily prove a huge amount. The firewall may allow ICMP messages through, but block TCP messages for the MUD port.

Nope, I've been trying for the last little bit, and I'm not able to connect at all, even with raw telnet. It's very likely that we do have some sort of a firewall. So, I'm not sure what the next step is to work around that (if it's even possible.)

There might not be a next step. For some reason they may not want you to play your MUSH at work.

I would try using a socks proxy server find one closest to where you work...

http://www.samair.ru/proxy/socks.htm
OR
http://nntime.com/socks/

They have them all around the world, and most of the ones with oddball ports work, and they all are supposed to be anonymous proxies, and some even have a port 80 connection, so that they can route through your port 80 to the mud's port. YOU WILL MOST LIKELY HAVE TO TRY 5 - 10 TO GET ONE THAT WORKS. TRY BOTH SOCKS 4 AND 5 ON EACH ONE YOU TRY, YOU MIGHT GET LUCKY.

Try that, and an extra feature is if your mud does not allow mplaying (multi-character playing) this makes it so that the character connected using the proxy 'appears' to be logged from the proxy server IP and not your own.

Enjoy :)
