15. Advanced Configuration
Similarly, the Primary unit will maintain a view of the status of the secondary units:
• Select Status: Support Report.
• Scroll down to Processes.
• Look for: /bin/ssh -MN -o ControlPath=/var/run/cascade/%h Secondaryname
These are the Secondary units that are connected.
• The end of the Secondary units’ names will be truncated, so the first five characters must be unique.
Alternately, you can write a custom CGI script as described above. The connected Secondary units can be determined
by running: ls /var/run/cascade. The configured Secondarys can be displayed by running: config -g config.cascade.

15.12 SMS Server Tools
Firmware releases V3.1 and later include the SMS Server Tools software, which provides an SMS gateway that sends and
receives short messages through GSM modems and mobile phones.
You can send short messages by simply storing text files into a special spool directory. The program monitors this directory
and sends new files automatically. It also stores received short messages into another directory as text files. Binary messages
(including Unicode text) are also supported (e.g., ring tone messages). It is also possible to send a WAP Push message to the
WAP / MMS capable mobile phone.
The program can be run as an SMS daemon, which can be started automatically when the operating system starts. High
availability can be ensured by using multiple GSM devices (currently up to 64, though this limit is easily changeable).
The program can run other external programs or scripts after events like receiving a new message and successfully sending a
message. It can inform when the program detects a problem. These programs can inspect the related text files and perform
automatic actions
The SMS Server Tools software needs a GSM modem (or mobile phone) with SMS command set according to the European
specifications GSM 07.05 (=ETSI TS 300 585) and GSM 03.38 (=ETSI TS 100 900). AT command set is supported. Devices
can be connected with serial port, infrared or USB.

15.13 Multicast
By default, all Tripp Lite console servers come with multicasting enabled. Multicasting provides Tripp Lite products with the
ability to simultaneously transmit information from a single device to a select group of hosts.
Multicasting can be disabled and re-enabled from the command line when used with firmware release version 3.1 and later. To
disable multicasting type:
ifconfig eth0 -multicast
To re-enable multicasting from the command line type:
ifconfig eth0 multicast
IPv6 may need to be restarted when toggling between multicast states.
