15.11 Custom Development Kit (CDK)

Copy scripts, binaries and conﬁguration ﬁles directly to the console server.

Tripp Lite also provides a free development kit that allows changes to be made to the software in console server ﬁrmware

image. The customer can use the CDK to:

• Generate a ﬁrmware image without certain programs such as telnet, which may be banned by company policy.

• Generate an image with new programs such as custom Nagios plug-in binaries or company speciﬁc binary utilities.

• Generate an image with custom defaults (e.g., it may be required that the console server be conﬁgured to have a speciﬁc

default serial port proﬁle which is reverted to in the event of a factory reset.

• Place conﬁguration ﬁles into the ﬁrmware image, which cannot then be modiﬁed. For example, # /bin/conﬁg –-set= tools

update the conﬁguration ﬁles in /etc/conﬁg which are read/write, whereas the ﬁles in /etc are read only and cannot be

modiﬁed.

The CDK provides a snapshot of the Tripp Lite build process (taken after the programs have been compiled and copied to a

temporary directory romfs) just before the compressed ﬁle systems are generated.

When the console servers are cascaded, the Primary unit is in control of the serial ports on the Secondary units, and the

primary’s management console provides a consolidated view of the settings for both its own and all the secondary unit’s serial

ports. However, the Primary unit does not provide a fully consolidated view. For example, Status: Active Users only displays

those users active on the Primary unit’s ports; you will need to write a custom bash script that parses the port logs if you want

to ﬁnd out who’s logged in to cascaded serial ports from the Primary.

You will also want to enable remote or USB logging. Local logs only buffer 8K of data and do not persist between reboots.

This script would parse each port log ﬁle line by line. For example, each time it sees ‘LOGIN: username’, it adds username to

the list of connected users for that port, and each time it sees ‘LOGOUT: username’ it removes it from the list. In doing this,

the list can be neatly formatted and displayed. It is also possible to run this as a CGI script on the remote log server.

To enable log storage and connection logging:

• Select Alerts & Logging: Port Log.

• Conﬁgure log storage.

• Select Serial & Network: Serial Port. Edit the serial port(s).

• Under Console server, select Logging Level 1 and click Apply.
