Question : Telnet access to Cisco 1841

I cannot connect via telnet to my router. It actually looks like I connect when I telnet from a DOS window but hitting any key drops me right out. I get the following debug messages:

089354: Jan 22 19:48:45.548: Telnet194: 1 1 251 1

Answer : Telnet access to Cisco 1841

line vty 0 4
 >authorization exec vty
 >no exec

Remove the "no exec"
(config)#line vty 0 4
(config-ln)#exec

Try again...
"no exec" means don't accept any commands coming IN to the interface from external device. Ergo, you get disconnected when you try to even send a carriage return..
