|[PLUG] Need Help with a script for netcat|
I have been having an issue getting a script to work running netcat in the background. I need to listen on a certain port for info coming from a PBX all day long. The PBX is sending SMDR data we want to use . ( call length, # of rings, etc....)
I have a script that does nothing but listen on a port for this info and appends a file with this data. If I run the script in the foreground, it runs all day and gives me exactly what I want.
If I run it in the background or as a daemon from /etc/init.d, it starts but then stops. If I do a ps -ef | grep for the process, the netcat proc is still running but nothing is listening
I have tried everything I can think of to keep it running, nohup the main script and the netcat command inside the script, ampersands, verbose mode to get a log, nothing will allow this to run in the background.
Here is the script I am running, its called get_smdr.sh
#!/bin/bash INFO=$(hostname | cut -c 4-7)_$(date +%Y%m%d) /usr/bin/netcat -l -n -p 6000 >> /tmp/smdr_$INFO
Any thoughts? Is there another way I can accomplish this strictly via the command line ?
Thanks very much for your thoughts,
