Chapter 15: Advanced Configuration
Console Servers run the embedded Linux operating system. So Administrato\
r class users can configure the Console Server and 
monitor and manage attached serial console and host devices from the com\
mand line using Linux commands and the config 
utility (as described in Chapter 14). 
The Linux kernel in the Console Server also supports GNU bash shell scri\
pt enabling the Administrator to run custom scripts. 
This chapter presents a number of useful scripts and...

15.1.2  Running custom scripts when alerts are triggered
Whenever an alert gets triggered, specific scripts get called. These s\
cripts all reside in /etc/scripts/. Below is a list of the default 
scripts that get run for each applicable alert:
• For a connection alert (when a user connects or disconnects from a port \
or network host):  
/etc/scripts/portmanager-user-alert (for port connections) or /etc/scripts/sdt-user-alert (for host connections)
• For a signal...

15.1.3  Example script - Power cycling on pattern match
If for example we had an RPC (PDU) connected to port 1 on a Console Se\
rver and also have some telecommunications device 
connected to port 2 and which is powered by the RPC outlet 3. Now assume\
 the telecom device transmits a character stream 
"EMERGENCY" out on its serial console port every time that it encounters\
 some specific error, and the only way to fix this error 
is to power cycle the...

15.1.5  Deleting configuration values from the CLI
The delete-node script is provided to help with deleting nodes from the command line. T\
he "delete-node" script takes one 
argument, the node name you want to delete (e.g. "config.users.user1" or "config.sdt.hosts.host1").
So delete-node is a general script for deleting any node you desire (users, groups, h\
osts, UPS's etc) from the command line. 
The script deletes the specified node...

15.1.6  Power cycle any device upon a ping request failure
The ping-detect script is designed to run specified commands when a monitored host sto\
ps responding to ping requests. 
The first parameter taken by the ping-detect script is the hostname/ IP address of the device to ping. Any other par\
ameters are 
then regarded as a command to run whenever the ping to the host fails. ping-detect can run any number of commands. 
Below is an example using ping-detect to...

15.1.7  Running custom scripts when a configurator is invoked 
A configurator is responsible for reading the values in /etc/config/config.xml and making the appropriate changes live. Some 
changes made by the configurators are part of the Linux configuratio\
n itself such as user passwords or ipconfig. 
Currently there are nineteen configurators each one responsible for a \...

To check if the backup was saved correctly: 
# /etc/scripts/backup-usb list
If this command does not display "* config-20May" then there was an error saving the configuration. 
The set-default command takes an input file as an argument and renames\
 it to "default.opg". This default configuration 
remains stored on the USB disk. The next time you want to load the defau\
lt config, it will be sourced from the new default.opg 
file. To set a config...

15.2 Advanced Portmanager
The portmanger program manages the Console Server serial ports. It routes network conn\
ection to serial ports, checks 
permissions, and monitors and logs all the data flowing to/from the po\
rts. 
15.2.1   Portmanager commands
pmshell
The pmshell command acts similar to the standard tip or cu commands, but all serial port access is directed via the 
portmanager.
Example: To connect to port 8 via the portmanager:
# pmshell -l port08
pmshell...
