Telnet fails with port 4444

Hi everyone,

I am using Olimex ARM-USB-OCD with OpenOCD v0.4.0. I haven’t built it but downloaded the ready version for Win32 from web.

Till few days back telnet to localhost was not working on my machine. But after googling I found that Windows firewall was preventing any access to telnet. Now telnet is working correctly(port 23). But still I am unable to telnet to port 4444.

I tried adding exception to port 4444 in firewall. But still the problem persists. And I didn’t find anything related to this problem on web.

I would be more than happy if you could help me with this.

Thanks in advance.

Try to:

  • add OpenOCD as exception in the windows firewall

  • disable the firewall, completely

If you can’t telnet again on port 4444 just change it in the cfg file:

telnet_port 23

I’ve just tried with OpenOCD 0.1.0 and it accepts connections on port 23 now.

Hey,

I didn’t know that telnet port for OpenOCD can be changed to 23 too. Thanks for that information.

Anyways, my problem is solved now. I made a rookie mistake. I used to close OpenOCD and then used to try telnet. :frowning: Then I figured out that I should run OpenOCD in 1 window and open Telnet in another at the same time.

I have intesionally noted my foolishness, so that other amatuares won’t carry this mistake.
