# SFTP

SFTP is a common protocol for business-to-business file transfer integration, and ExaVault supports it as a first-class connection method.

## Connection Settings

Two values configure an SFTP client to reach your ExaVault appliance: the hostname and the port.

### Hostname

Connect with SFTP to the fully qualified domain name of your appliance. If the client requires an IP address, use the external IP address configured in the Appliance Manager.

### Port

For SFTP connections, use port `22`.

Before distributing connection settings, retrieve the appliance's deployment-specific key and configure clients to verify it. See [Verifying the SFTP Host Key](/connection-methods/sftp/verifying-the-sftp-host-key.md).

## SCP (Secure Copy) Protocol

ExaVault's SFTP server also supports the SCP protocol, another file transfer protocol built on top of SSH. In most interactions with ExaVault, SCP works the same as SFTP.

## SSH Restrictions

SSH functionality is restricted to SFTP and SCP file transfer and SSH-key authentication. Shell access and SSH tunneling are not available.

Security scans may report that SSH is available because SFTP and SCP run over SSH. This does not indicate that interactive shell access or SSH tunneling is enabled.
