on the putty window because i was accessing from outside
connection was completed, and it runs as usual, no trouble faced, i can do things that i usually do on my box.
1) A bug in putty. Not likely because a quick look at the putty source shows no file make_cmd.c
2) A bug in your server code (I assume openssh). Possible. With a slow internet connection, I can't take a quick look at that, too much downloading going on..
3) A bug in a command that you're running.
4) A hardware error.
5) A configuration error.
6) Evil hackors own your box.
Having used putty to log into many linux boxes, but with no knowledge of the inner workings, my guess would be option 5 is most likely. If you have access to newsgroups, try posting to comp.security.ssh with as much info as you can.
