I don't know if this is a Linux Mint problem or a Debian problem. I use Mint as a desktop but I just installed a standard no GUI edition of Debian for my media server. I was going to use the Mint file browser Nemo to connect to the Debian server so it would be easier to copy files to and from but when I enter all the credintials into the connection box and click connect I get this error -> Host key verification failed
I can connect to the Debian server from my Mint desktop just fine through standard SSH.
I've always been able to connect to other systems through Nemo before, any ideas on what's going on? Thanks.

Since these systems are both behind your router/firewall, don't bother with SSH but enable telnet and FTP. SSH will require in some cases that your client is registered with the host account (login ID) that you are using, with its public key. Your client needs to use the private key so that the server can validate you. A PITA, but that's the way it works, which is why for local LAN connections I don't bother with SSH usually.

Like rubberman says, SSH can be an annoying method. The problem with trying to rely on SSH connections via GUI applications (like a file explorer) is that SSH can sometimes issue warnings about keys that have changed or otherwise ask for additional steps. In some cases also, the GUI application uses a different user-id, which causes more issues in some setups (like with RSA keys or key-chains).

One alternative is to rely on a simpler (less secure) protocol like telnet or ftp, as rubberman suggests.

Another alternative, if you don't want to compromise on security, is to use something like SSHFS, which allows you to mount a remote file-system through SSH. In that case, you would just mount the remote file-system through the terminal, and then that folder (destination of mount) can be accessed by your GUI file explorer (or any other program) just as a normal folder. And because the mounting is done manually in the terminal, the issues with having a GUI deal with the SSH connection are eliminated.

Are there two versions of telent? Do I need to install telnet server on my Debian server and a telnet client on my desktop?
