Hello,

Anyone have any issues Reverse Telnetting into a 2501 via a 2509 using a Async cable? I have a 1924 , 2509, 2521, and two 2501's. I pretty much slapped default configs on all and wanted to start with getting the Access Server (2509) configured first. So, I added the ip hosts on the 2509 and configured the lines (1-8) and connected to each device via the console port. The 2509 can telnet into the 2521 and 1924, but on both 2501's, I get: connection refused?

I have done some research, and found a few things to look try. Just wondering if anyone has any pointers that can save me some time.

Thank you!

Hello,
I found that "clear line" allows me to utilize the line. But does anyone know what can be causing it to lock up? I can now R-Telnet in, but only after I issued the clear line command on both lines.
Any help would be appreciated.

This is a timeout issue. Need to set a time out on the console and the line. Try setting an Exec time-out on the console of the 2501.

This may help.
 
There is no problem. you can put timeouts on the routers that are attached, i.e. 2501s, etc..

line con 0
exec-timeout 3 0

This will do 3 minutes..

On the 2509, you can use infinity

line con 0 or line vty 0 4
exec-timeout 0 0

When this happens, write the command clear line as mentioned..the Number simply designates which ASYNC line it's on. your octal cables should be numbered

clear line 1
[confirm]
repeat that command about five times to "break" the console
then type the hostname, it'll open.......
using the up arrow key to repeat the line would be up, enter, enter, .....

Lastly, on another note, aside from this, you can specify the tranport on the async line.
all but the 2509...

line con 0
tranport input telnet (or none)
stopbits 1

good luck...


As Always........
