SSH Known Hosts
Specify the file which includes a name of Host connected via SSH (and Public key for Host).
Host key rotation
Configure the host key rotation feature(OpenSSH 6.8 or later).
Do not update the known hosts file.
Automatically update the known hosts file.
A user is asked to confirm the modifications to the known hosts file.
HeartBeat (keep-alive)
A Keep-alive packet is sent on a regular basis to maintain the connection (particularly useful under NAT). If 0 is specified, this feature is disabled.
Remember password in memory
The user password is preserved in the memory. The password in the memory is used by "Duplicate session" function. The password is deleted in the memory when Tera Term session disconnects.
Enable agent forwarding
The SSH agent forwarding is enabled using by the Pageant application.
Confirm agent forwarding
When the SSH agent-forwarding is requested, a user will confirm contacting the Pageant.
Verify host key fingerprint by DNS
The host key of the SSH server is verified by using the SSHFP Resource Record.
The result of this verification should be used only as a guide.
KEX order (SSH2 only)
Specify the type of KEX(Key Exchange) for SSH2 with the order.

Compression order (SSH2 only)
Specify the type of compression key for SSH2 with the order.
<Compressions below this line are disabled> Delayed compression(Starts compressing after authentication)
none No compression
Compression level
Specify the level of compression for transmission. The more right, the more compression is done (note: it may degrade the throughout with a high-speed link such as ADSL or FTTH).
By using SSH1 protocol, when the Compression level is 0, the packet compression is disabled, or the Compression level is over 1, the compression is enabled.
By using SSH2 protocol, use the Compression order to enable the packet compression. And then, set the Compression level to 1 over.
