I want to enable telnet in my router (ZTE F670L V9.0.11P1N20D), So, I backup my router and i have a file config.bin, Size 23.5KB. I fired up kali and when i issue this command:
$ file config.bin
config.bin: OpenPGP Public Key
I got this above output, I tried to extract this via binwalk, but no success.
Even though, Telnet is enabled on my router by default but the port is filtered:
PORT STATE SERVICE
21/tcp open ftp
23/tcp filtered telnet
53/tcp open domain
80/tcp open http
139/tcp open netbios-ssn
443/tcp open https
I tried resetting the router but still Port is filtered.
So, I hope there's a solution to extract that config.bin.
