Server settings

 

Port

The port on which !MC5 listens for incoming SFTP connections. Default port for SFTP is port 22, your network configuration (firewall rules and port forwarding) must be adjusted accordingly. Note that this port is also the default port for SSH and is therefore very often "captured" by port scanners. So there may be a lot of "connection from unknown". This is unfortunately normal and is not a big danger. !MC5 has no internal default accounts, a login is only possible with the usernames and passwords specified in the SFTP partners settings. The SFTP server of !MC5 does not provide any shell access and does not allow any tunneling or similar. Each partner sees only the files that are provided for him and can neither change to another directory nor see other directories. The only allowed actions are uploading and downloading files.

 

Timeout (s)

Time after which an existing connection is terminated due to inactivity.

 

Authentication algorithms and keys

The authentication algorithms and keys used by the server. The algorithms can be enabled and disabled using the corresponding checkboxes. Keys can be (re)generated and the public keys can be displayed via the context menu.

 

RSA - The most common key algorithm. Using RSA is the best choice to be compatible with as many SFTP clients as possible.

DSS (DSA) - Rarely used anymore, as the algorithm is now considered too insecure.

ECDSA - Modern and secure variant of DSA.

EdDSA - Algorithm based on ECDSA that is considered superior to both ECDSA and DSA. Generally supported only by newer SFTP clients. When Ed25519 is mentioned, it means EdDSA using the 25519 curve.
