HAPTER NSTALLATION AND ONFIGURATION
compat 1
Specifies to be compatible with the previous router versions, but some terminal
access features will not be available. The default is 0, indicating incompatibility
with the previous router versions.
The ttyd configuration file supports dynamic adding. That is, after ttyd is started,
the corresponding terminal configuration items can be added. The addition takes
effect after connection requests are initiated from the terminals connected to the
router or after the configuration file is refreshed with the ttyadm program,
without the need of restarting the ttyd program.
Addition takes effect automatically. For modification and deletion to take effect,
however, the configuration file must be refreshed.
Normally, you need to configure items 1, 2, 4, 9, 11, 12, and 13 as required and
use defaults for other items.
n
When too many terminals are configured in a configuration file, the file is liable to
be modified improperly. Therefore, you are recommended to configure multiple
configuration files on a Unix server with many pseudo terminals, so that a
configuration error does not affect too many applications.
Modifying Route In terminal access, the router is usually connected to the Unix server through
Configuration File WANs and therefore located on an IP subnet different from that of the Unix server,
in which case you must configure a route on the Unix server. The following
example shows how to do so:
# route add 10.110.96.0 -netmask 255.255.255.0 63.1.1.250
In the example above, 10.110.96.0 is the destination subnet, with the subnet
mask of 255.255.255.0 and the next hop IP address of 63.1.1.250.
Running and Running ttyd
Terminating ttyd on
You can run the ttyd program after the installation and configuration After
Unix Server
installing the device drivers and configuring the configuration files, you can run
the ttyd program as long as you can ping through the router from the Unix server.
Execute the following command to run the ttyd program.
# /etc/ttyd
If you do not specify any parameters for the command, the default configuration
file /etc/ttyd.conf is used. To specify another configuration file, you must enter file
in the following format:
# /etc/ttyd /etc/ttyd9020.conf
A Unix server can run multiple ttyd programs, each of which must use a unique
configuration file and a unique listening port.
You can enter the following command to view the version of ttyd.
# /etc/ttyd -h
