KC6HUR's Scripts

One of the best things about the IRLP system is the ability to extend the capabilities of a node by writing programs or scripts to perform some needed function. While most programs are written using the bash shell scripting language, you can write programs in whatever language you so desire, be that bash, Perl, c, etc. The functions can then be executed by the custom_decode control script, from the console, at startup, or via the cron timed execute functions. You can do just about anything.

Below is a collection of scripts that I have written, adopted or just modified to suite my own needs. They work for me. I'm offering them to the IRLP public with the hopes that they may meet your needs as well. Feel free to examine them, use them, modify them.

No Warranty is expressed as to their suitability or stability. They may break your system. If you ask nice enough, I may even help you fix them on your system. Enjoy!!

Special Notes

Ever since TWIAR started creating Pod-casts of their broadcasts, mpg123 won't play the twiar.mp3 file; therefore, it is necessary to install mpg321. The procedure below can be used to download and install all the required files (works for FC5, too):

yum -y install libao
wget http://dag.wieers.com/packages/mpg321/mpg321-0.2.10-8.fc3.rf.i386.rpm
wget http://dag.wieers.com/packages/libid3tag/libid3tag-0.15.1b-3.1.fc3.rf.i386.rpm
wget http://dag.wieers.com/packages/libmad/libmad-0.15.1b-4.fc3.rf.i386.rpm
rpm -ivh libmad-0.15.1b-4.fc3.rf.i386.rpm
rpm -ivh libid3tag-0.15.1b-3.1.fc3.rf.i386.rpm
rpm -ivh mpg321-0.2.10-8.fc3.rf.i386.rpm

Edit the playnews script:
OLD:
/usr/local/bin/mpg123 ${1}.mp3
NEW:
/usr/bin/mpg321 -o oss ${1}.mp3

Edit the stopnews script:
OLD:
/usr/bin/killall mpg123 &>/dev/null     # kill the local player

NEW:
/usr/bin/killall mpg321 &>/dev/null     # kill the local player

How-To Download

I always hate downloading using a browser on a Windoze box than having to transfer it over to the Linux machine. While my site looks good using a program such as Internet Explorer, because of the way my site is designed, it is extremely easy browse using lynx (a text based browser) which runs on the Linux machine. The beauty of using lynx to download the files from my site is that it saves the file directly to the Linux machine and you don't have to worry about ASCII files getting CRLFs added to the files.

You can also use wget to download files directly your Linux machine; however, you will have manually type in the URL of the file you wish to get. Use lynx, it's easier; however, if you have trouble, then it might be necessary to use wget.

To learn more on how to use lynx and wget, please refer to the man pages on the Linux machine.

Download Scripts

This site is going through some major changes. All downloadable scripts are being converted into .rpm package. By doing this the installation, uninstalling and updating will be much easier. Eventually the .rpm files will perform dependancy checking and may even be able to perform some of the more difficult installations steps.

When these rpms are installed, a new directory /home/irlp/docs is also created to hold the documents for the these scripts. Maybe, man pages will be added in the future.

aprs_status-4.0.tgz	Report the status of your node via APRS INSTALLATION ============ 1. Login is as root. 2. Get the tar file: wget http://irlp.kc6hur.net/downloads/aprs_status-4.0.tgz 3. Install the files found in the tar file: cd / tar -xzvf /root/aprs_status-4.0.tgz This will un-zip the files and place them in the appropriate directories. 4. Read the README_aprs file in /home/irlp/custom directory for the rest of the instructions.
confirm-1.0.0-1.i386.rpm	Provides an audible confirmation of a received DTMF command.
cos_watch-1.0.0-1.i386.rpm	Prevents remote IRLP connections from butting into a local conversation.
cwtext-0.91b.tgz	A CW generator that outputs to the /dev/dsp device. While I have not tested it with IRLP under FC3, according to Dave VE7LTD, it should work along with IRLP. I have modified this version so that cwpcm allows the setting of tone frequecy (pitch) and level (volume) from the command line. Be sure to read the README file. Login as root `wget http://irlp.kc6hur.net/downloads/cwtext-0.91b.tgz` `tar -zxvf cwtext-0.91a.tgz` `make clean` `make` `make install`
fastdtmfdial	Play DTMF tone very fast (programmable speeds and volume).
force_exec-0.2.0.tgz	This program makes it possible to force the execution of a DTMF command rather than waiting for the COS to drop. See the README file in the tarball. Version 0.2.0 was released to support future operation under Fedora Core 2 and will utilize either /dev/irlp-device or the parallel port device which will be required by later version of IRLP. This is a whole new version, written in C and released on September 23, 2004. Login to your node as repeater and enter the following command: `wget http://irlp.kc6hur.net/downloads/force_execute-0.2.0.tgz` then untar the tarball: tar zxvf force_eceute-0.2.0.tgz cd to the force_exec directory and follow the instructions found in the README file. OK: RH9 and FC3
guardtone.tgz	This program allows an IRLP node to "look" like a microwave receiver when connected to a voter such as a Motorla SpectraTAC comparator. The guardtone program will generate a guard tone whenever the PTT unkeyed.
ID-2.0.1-2.i386.rpm	Send CW ID using sccw or .wav file. This version of the ID program uses an improved algorithm for generating the IDs. IDs will be sent in manner very similar to those done by modern repeater controllers. JUL-16-2005: this version will also work with ALL versions of IRLP boards. There is a variable in the in the ID program where you tell it if you are using a Ver 3 or not board. NOTE: When in non-Ver 3 mode, the ID take precedence over voice comm, sorry, no other way to do it cleanly.
IRLP Basic Flowchart (pdf)	The chart that show the flow of control in the IRLP system.
local_echo	Echo audio without going to the echo reflector.
mpg123-0.59q-1.i386.rpm	mpg123-0.59q-1.i386.rpm OK: RH9 and FC3
playnews.tgz	Play Amateur Radio audio news files. Login as repeater; then enter the following: `wget http://irlp.kc6hur.net/downloads/playnews.tgz` `tar zxvf playnews.tgz` `cd playnews` `./install` Please read the README file. See Special Notes above!!!
random_call	Randomly dial a node.
sccw_1.1b.tgz	sccw_1.1b - Use sound card synthesizer to generate CW Copy this tarball to your `/home/irlp` directory Install it: `tar -zxvf sccw_1.1b.tgz` Follow the `README` OK: RH9 and FC3
setrlcclock	Used to set the clock on a LinkComm RLC controller using DTMF Make sure you have fastdtmfdial installed.
speaktime-2.0.0-1.i386.rpm	Speak the time of day.
star69-2.0.0-1.i386.rpm	Speak/Call last callwaiting, incoming, outgoing calls.
star69	Fixed Star69 as of June 11, 2007. Download this file to replace the star69 file in your $CUSTOM directory. Fixes problems in handling dates.
text2dtmf-1.0.1-1.i386.rpm	Send text messages to Yaesu FT-51R.
text2wave	Festival text to wave control script (scheme) file.
tone_0.3.tgz	tone_0.3 - Dual tone generator using sound card synthesizer Copy this tarball to your `/home/irlp` directory Install it: `tar -zxvf tone_0.3.tgz` Follow the `README` OK: RH9 and FC3
timeout	Used to Enable/Disable the activity timeout timer and report the status of this setting.
usrcmds	Used to Enable/Disable the user function commands and report the status of this setting.
wx_rpt.tgz	This tarball contains the scripts and file necessary to automatically generate weather reports on your IRLP node. NOTE: THIS IS ALPHA GRADE SOFTWARE. It will require that you have VERY good knowledge of Linux, bash and Perl coding. It is being offered at this time with NO offer to help you get it installed and working. It WILL NOT work out of the box. I may provide pointers but that is about all at this time. See the README file for more information. Good Luck! OK: RH9 and FC3
fmh1.pdf	This is the official manual from the Department of Commerce/NOAA; Office of the Federal Coordinator Meteorological Services and Supporting Research, titled Federal Meteorological Handbook No. 1 Surface Weather Observations and Reports and is the manual which provides the specifications for coding/decoding the information in the METAR reports. FMH-1 is the guide used in developing the metar2text program.
