TCP/IP AX3000 User's Manual 85
5.4.4 -The axttyd Mechanism
The axttyd daemon performs the following steps:
- init stage: association file checking (errors are reported in the log file)
and associated ptty opening (masters and slaves),
- rtty stage: for each rtty association, a child process is created. Each
child process listens on the associated ptty. When data is received a
socket is opened on the AX3000 auxiliary port. Bi-directional
communication is then enabled. If no data is sent or received for any one
minute interval, the connection is closed. It will be opened again, the next
time data is received from the ptty.
- tty stage: when all the rtty child processes are created, the axttyd
daemon listens on the TCP/IP socket (generally 2048). For each
connection request (from an AX3000 tty service), a child process is
created. This process controls communication between the ptty and the
AX3000 resource (session or auxiliary port).
5.4.5 - Uninstalling
Remove the AXEL files and kill the AXEL tty server process (signal TERM):
# kill -TERM pid<CR>
where pid is the process ID of the AXEL tty server.
5.5 - REMOTE ADMINISTRATION
The following rsh commands allow an AX3000 to be controlled over the
network. (on SCO OpenServer the rsh command is called rcmd).
5.5.1 - Rebooting the AX3000
To reboot an AX3000 over the network, invoke the following command:
# rsh axname ax_reboot password
Where:
- axname : AX3000 name (/etc/hosts) or IP address,
- ax_reboot : command for AX3000 reboot,
