Hi, I have setup a dynamic dns: hostname.cz.cc host, I can access ftp, webserver..etc no problem, but when I try to telnet, it doesn't appear to be right. I have the telnet port 23 enabled.
When telnet locally, via IP eg. 192.168.x.x, or host name "nas" both works fine:

Code:



sh-3.1# telnet nas

Trying 192.168.2.101...

Connected to nas.

Escape character is '^]'.



nas login: root

Password:



BusyBox v1.14.2 (2010-06-21 19:41:28 BRT) built-in shell (ash)

Enter 'help' for a list of built-in commands.

Works fine; but when telnet remotely:

Code:

sh-3.1# telnet hostname.cz.cc

Trying A.B.C.xx...

Connected to hostname.cz.cc.

Escape character is '^]'.

login: root

Login incorrect

Why is that?
the "nas login" became "login" and I tried many times but doesn't work :/
THanks,
Ted

sorry, my bad, didn't double check, i added the port to the router but didn't click on the enable button. sorry XD

You should not remote telnet and certainly not access services as root user: use SSH as unprivileged user. If your NAS doesn't support SSH then at least ssh into your bastion host as unprivileged user and telnet from within your own LAN range.
