I have an assignment that requires remote access into some Cisco routers. According to Netlab, it uses TCP port 23.
I’m unable to pass the port test. I’m on Windows 7, I’ve tried all major browsers. I’ve disabled Windows Firewall and even connected directly to the modem. My ISP is Cogeco but I’ve tried tethering to my iPhone (Rogers) which produced no success.
After some reading it was suggested to go into Windows Features in the control panel and turn on Telnet. I did that, and made sure to set the Telnet service to manual and start it in services.msc. Still, I’m unable to pass the port test.
I’ve checked this website: http://www.t1shopper.com/tools/port-scan/
and it confirms than I’m unable to connect to Port 23.Would anyone have any suggestions? My timeslot for the lab is in a couple hours and I’m not sure why it is giving me such a hard time. I’ve managed to use this machine previously to do the lab, albeit on a different connection (not the school’s though).
Here is the error message I’m getting:
aptest PING_IO_ERROR: Connection timed out: connect aptest all ports failed aptest callback (STATUS_NO_OPEN, null) aptest js result=STATUS_NO_OPEN param1=null
Answer
When they said to turn on telnet, they meant to install the telnet client, not the service. Once you have the telnet client installed open a command prompt and type in
telnet [servername]
if that doesn’t work, download putty and give that a try.
Other than that there are so many unknowns about the environment. Are you supposed to be connecting to the router over the cloud or is there somewhere you are supposed to VPN to first?
