Hey, i have a Problem with the TELNET, when i connect via putty, it shows me 220 Operation successful.

But when i try to execute a command it only shows 500 Unknown command. (The commands are right, they are from the guides of this forum)

Someone know what to do, to fix this?

Telnet is on port 23, not 21=FTP

oh man, so simple haha
i searched the problem on google and there were only results with downgrade firmware and something like that. Good that i asked here.
thanks a lot
