Startup Line Parameters
SSH2 configuration parameters can be passed on the startup line as follows:
<parameter name> <parameter value>; <parameter name> <parameter value>; ...
The following example demonstrates how to start multiple SSH2 instances that share the same SSHCONF configuration
file listening on different subnets using the same port:
> PARAM CONFIG SSHCONF
> RUN SSH2 /NAME $SSH00, CPU 0, NOWAIT/ SERVER; SUBNET $ZTC0; PORT 22
> RUN SSH2 /NAME $SSH01, CPU 1, NOWAIT/ SERVER; SUBNET $ZTC1; PORT 22
> RUN SSH2 /NAME $SSH02, CPU 2, NOWAIT/ SERVER; SUBNET $ZTC2; PORT 22
> RUN SSH2 /NAME $SSH03, CPU 3, NOWAIT/ SERVER; SUBNET $ZTC3; PORT 22
For a complete description of the RUN SSH2 command, see the "Starting SSH2" section.
Starting SSH2
Note: The SSH2 process must be started and run under the SUPER.SUPER logon. When started using a different user
ID, the process will issue a warning message and terminate.
You create a SSH2 process by issuing a TACL RUN command using the following syntax:
RUN SSH2 / runoptions / mode [ ; paramname paramvalue; ... ]
Following is a description of each aspect:
• runoptions are the standard Guardian RUN options, such as IN, CPU, or TERM.
• mode defines the "run mode" of the SSH2 process. The so-called run mode defines which functionality that
instance will allow. The following run modes are defined:
DAEMON
runs a daemon process that provides the SFTP service to remote clients. No other
functionality is provided.
DAEMON_ADMIN combines the run modes DAEMON and ADMIN
CLIENT
runs a process that allows local SFTP clients to connect to the SSH2 process. No other
functionality is provided.
CLIENT_ADMIN combines the run modes CLIENT and ADMIN
ADMIN
runs a process that allows SSHCOM instances to connect to the SSH2 process and to
configure the user database. No other functionality is provided.
NOADMIN combines the run modes DAEMON and CLIENT
ALL combines all run modes
(SERVER can be used instead of DAEMON)
• paramname paramvalue; ... is a list of SSH2 configuration parameter settings as described in the previous
section.
Note: When you start SSH2 in NOWAIT mode, make sure you have disabled logging to the home terminal. To do so,
set the following PARAM:
