2.7 Configuring Network Settings
uses host keys to uniquely identify each SSH server. Host keys are used for server authentication
and identification. A secure unit permits users to create or delete RSA or DSA keys for the
SSH2 protocol.
The SSH tools supported by VersaSync are:
SSH : Secure Shell
SCP : Secure Copy
SFTP : Secure File Transfer Protocol
VersaSync implements the server components of SSH, SCP, and SFTP.

To configure SSH:
1.
Navigate to MANAGEMENT > NETWORK: SSH Setup . The SSH Setup window will dis-
play.
The window contains two tabs:
Host Keys
You may choose to delete individual RSA or DSA host keys. Should you decide to delete the
RSA or DSA key, the SSH will function, but that form of server authentication will not be avail-
able. Should you delete both the RSA and DSA keys, SSH will not function. In addition, if SSH
host keys are being generated at the time of deletion, the key generation processes are
stopped, any keys created will be deleted, and all key bit sizes are set to 0.
You may choose to delete existing keys and request the creation of new keys, but it is often sim-
pler to make these requests separately.

Note: Only SSH2 is supported due to vulnerabilities in the SSH1 protocol.
