Tectia Features
Tectia provides limited support for SSH-1, mostly by running programs from some older implementation whenever the SSH-1 protocol is required. Some of the Tectia programs do have built-in support for SSH-1, however.
Serverwide Configuration
The Tectia server has no built-in support for SSH-1, but it can be configured to run a separate SSH-1 server for SSH-1 clients. See "Compatibility Between SSH-1 and SSH-2 Servers" in Chapter 5.
The following keywords in the /etc/ssh2/sshd2_config file control SSH-1 compatibility mode:
Ssh1Compatibility
Run the SSH-1 server when SSH-1 clients connect (if
yes
).Sshd1Path
The pathname for the SSH-1 server.
Sshd1ConfigFile
An alternate configuration file for the SSH-1 server, replacing the one specified for the Tectia server by the -f command-line option.
Client Configuration
The ssh -1t option runs an SSH-1 client program, and ssh -1i uses built-in SSH-1 emulation. See "Choosing a protocol version" in Chapter 7.
The following keywords in the /etc/ssh2/ssh2_config file control SSH-1 compatibility mode:
Ssh1Compatibility
Use SSH-1 if the server supports only supports the older protocol (if
yes
), or otherwise fail (ifno
).Ssh1InternalEmulation
Use the Tectia client’s built-in SSH-1 functionality (if
yes
), or otherwise run an external SSH-1 program (ifno
).Ssh1Path
The pathname for the external SSH-1 program.
Ssh1MaskPasswordLength
Send SSH_MSG_IGNORE packets with SSH-1 sessions to obscure the length of the password (if yes, the default). Otherwise, ...
