I am trying to connect to a device that use telnet, I tried to do it with medusa coming with Back Track 4 beta.

medusa -h 192.168.1.1 -P passnu.txt -M telnet

I got an error, so I typed:

medusa -h 192.168.1.1 -u root -P passnu.txt -M telnet

I got:

ERROR: telnet.mod. No login prompt detected.

I know that there is not login, but how I tell to medusa that do not use login?

Thanks

When you connect to the device on port 23 what do you see? Nothing?

Can you get a raw netcat output so we can see what it looks like?
1. nc 192.168.1.1 23 > output.txt
2. wait a few seconds, then Ctrl+C
3. Post the output.txt
