Model: Archer C2  
Hardware Version: V1
Firmware Version: 0.9.1 5.0 v0032.0 Build 170207 Rel.49213n

Hi

 

I have an Archer C2 750 router. I ran nmap  192.168.0.1 from my computer and it reported that these are available :

 

22/tcp   open  ssh
23/tcp   open  telnet
80/tcp   open  http
1900/tcp open  upnp

 

I wasn't able to ssh into it, the following link states that its for use with an app only, no login. is that correct?

https://forum.lowyat.net/topic/4282635/all

 

Can I shutdown or limit telnet? I was able to limit login over http to one computer on the local network, didn't affect telnet which was still accessable by others.

 

What is upnp for? I switched off upnp via admin webpage and nmap reports service ir running (or port is open anyway)

 

Thanks,

Rob

Hello, the Archer C2 supports Tether app, and the app uses SSH22. You can read this article. https://www.tp-link.com/support/faq/2462/

 

The Archer C2 has the built-in web management page, which uses http port 80. 

 

The UPnP (Universal Plug and Play) protocol allows the applications or host devices to automatically find the front-end NAT device and send request to it to open the corresponding ports.

 

While for the telnet, as far as I know, it is disabled by default; we can access the web UI with the local login only; you can try to use telnet to access the router to rule out the flaw of nmap software. 

 

May it help.

@Kevin_Z 

 

Thank you very much for replying, just realised I hadn't replied myself.

 

Yes, it covers it all. Telnet it accessable from this model, thankfully only from LAN. I did a scan from at home and those ports showed up, panic on. It wasn't until after I posted I did a scan from a friends house an nothing showed up. So with your great explanation, panic off.

 

Thank you again,

rob
