SSH Reference Manual

The Configuration File
Configuration files can be modified with a standard NonStop editor, such as TEDIT. The name of the file that a SSH2
process should use as the configuration source is passed to the program during startup. (See the "Starting SSH2
" section
for details.)
The file contains entries in the following form:
parameter-name parameter-value
Like in the standard TCP/IP configuration files, any lines starting with a "#" character are interpreted as comments.
Following is a sample configuration file for running SSH2 as a server that provides SFTP functionality:
# sample configuration file for a SSH2 server
#---------------------------------------------------------------------------------
# general settings
# TCP/IP process the server runs on
SUBNET $ZTC1
# port where SSH2 listens for incoming SSH connections
# we use the well-known SSH port
PORT 22
# file name of host key file
HOSTKEY hostkey
# file name of user database file
SSHCTL SSHCTL
#---------------------------------------------------------------------------------
# log configuration
# set the level
LOGLEVEL 50
# enable console logging to $0
LOGCONSOLE $0
# additionally log to file
LOGFILE $data1.ssh2.ssh2log
PARAM Commands
The following PARAM command can be used to set SSH2 configuration parameters:
PARAM <parameter name> <parameter value>
If the parameter value contains one or more commas, it must be included in double quotes (see PARAM command in the
NonStop™ "TACL Reference Manual" for use of comma as separator):
PARAM <parameter name> "<parameter value>"
All available SSH2 parameters can be specified using PARAM commands. But please be aware of the limitations
described in the TACL Reference Manual: "TACL reserves 1024 bytes of internal storage for parameters and their
values. The number and length of parameters in effect are limited by this storage area."
The following example demonstrates how to use a PARAM command to start an SSH2 server listening on $ZTC03, port
22:
> PARAM PORT 22
> PARAM SUBNET $ZTC03
> RUN SSH2/ NAME $SSH02 / SERVER
