This script gives you the ability to query your IRLP node's uptime from your DTMF keypad.  It can be downloaded here:

http://rob.pectol.com/irlp/scripts/uptime.sh  
or here http://www.w2ymm.net/irlp/scripts/uptime.sh

 

It uses a text to speech engine (Festival) to report back, in voice, how long your node 

has been up since the last reboot.  To make this work on your node, simply install 

Festival (do, "yum install festival" as root, without quotes) and then place my system 

uptime script (uptime.sh) in your /home/irlp/custom directory.  It supports AUX line PTT 
for those nodes that are configured for it.  Simply open uptime.sh in a text editor and 

modify the, "user configurable settings" near the top of it.  Then, make sure it is 

owned by user repeater and in group repeater.  Also make sure it is set executable 

(chmod 750 uptime.sh).  At this point, you should be able to run it from the command 

line and have it announce your node's uptime!  If you want to be able to call this 

script from your DTMF keypad, simply add the following to your 

/home/irlp/custom/custom_decode file:

 

 # report the system uptime
if [ "$1" = "AA" ]; then
    $CUSTOM/uptime.sh & >&/dev/null 2>&1
    exit 1
fi

 

This would cause the DTMF sequence, "AA" to call the uptime.sh script!  Enjoy! 
Note I modified the script once on my machine to utilize my TTS voice
from Cepstral (David) instead of the Festival voice.
Here is what I did. Bob P W2YMM
# announce the node's uptime
echo "$announce_uptime" | #festival --tts # Commented out Festival to use Cepstral
/usr/local/bin/swift -n David -f -   # Added this line to utilize my Cepstral TTS Voice David
