I want to create web service for my Phonegap Android application which will further call progress 4GL 91.D procedure.
Does any one knowy idea how to create web service for this.
That will be a struggle. You CAN create a server that listens to a socket but you will have to handle everything yourself!
Look at this example.
However, you are likely better off writing the webservice in a language with a better support and then finding another way of getting the data out of the DB. If youre really stuck with a 10+ year old version you really should consider migrating to something else.
You don't have to upgrade everything -- you could just obtain a license for a version 10 client. V10 clients can connect to v9 databases (the rule is that the client can be up to one major release higher) so you could use that to build a SOAP service. Or you could get a v10 "webspeed" license.
Or you could write a simple enough CGI wrapper to some 4GL code if you have those sorts of skills. I occasionally toss together something like this:
#!/bin/bash
#
LOGFILE=/tmp/myservice.log
SVC=sample
# if a FIFO does not exist for the specified service then create it in /tmp
#
# $1 = direction -- in or out
# $2 = unique service name
#
pj_fifo() {
if [ ! -p /tmp/$2.$1 ]
then
echo `date` "Creating FIFO $2.$1" >> ${LOGFILE}
rm -f /tmp/$2.$1 >> ${LOGFILE} &2>&1
/bin/mknod -m 666 /tmp/$2.$1 p >> ${LOGFILE} &2>&1
fi
}
if [ "${REQUEST_METHOD}" = "POST" ]
then
read QUERY_STRING
fi
# header must include a blank line
#
# we're returning XML
#
echo "Content-type: text/xml" # or text/html or text/plain
echo
# debugging echo...
#
# echo $QUERY_STRING
#
# echo "<html><head><title>Sample CGI Interface</title></head><body><pre>QUERY STRING = ${QUERY_STRING}</pre></body></html>"
# ensure that the FIFOs exist
#
pj_fifo in $SVC
pj_fifo out $SVC
# make the request
#
echo "$QUERY_STRING" > /tmp/${SVC}.in
# send the response back to the requestor
#
cat /tmp/${SVC}.out
# all done!
#
echo `date` "complete" >> ${LOGFILE}
Then you just arrange for a background session to be reading /tmp/sample.in:
/* sample.p
*
* mbpro dbname -p sample.p > /tmp/sample.log 2>&1 &
*
*/
define variable request as character no-undo.
define variable result as character no-undo.
input from value( "/tmp/sample.in" ).
output to value( "/tmp/sample.out" ).
do while true:
import unformatted request.
/* parse it and do something with it... */
result = '<?xml version="1.0"?>~n<status>~n'.
result = result + "ok". /* or whatever turns your crank... */
result = result + "</status>~n".
end.
When input arrives parse the line and do whatever. Spit the answer back out to /tmp/sample.out and loop. It's not very fancy but if your needs are modest it is easy to do. If you need more scalability, robustness or security then you might ultimately need something more sophisticated but this will at least let you get started prototyping.

I am trying to install net-snmp from scratch to make snmpv3 to work on my computer.
I did install net-snmp and create the user, but when I want to make snmpget it reject me with snmpget: Unknown user name
To install net-snmp I followed the official guide
I did install the packages libperl-dev, snmp-mibs-downloader and snmp too using sudo apt-get install

Here is my persistant configuration file /var/net-snmp/snmpd.conf

The command I run is :
snmpget -u neutg -A password -a SHA -X 'passphrase'
-x AES -l authPriv localhost -v 3 1.3.6.1.2.1.1
I don't understand why it do not take in count my user. (I did restart the snmpd after entering the user - multiple times!)
The version of net-snmp I use :
Thanks in advance :)
After many research I've found what the problem is.
snmpd was not taking in count my configuration files. I saw it using the command :
snmpd -Dread_config -H 2>&1 | grep "Reading" | sort -u
Which tells you which configurations files are loaded by snmpd.
You can see it as well looking at the configuration file /var/lib/snmp/snmpd.conf. When snmpd handle your users it creates special lines in the file. It looks like :
usmUser 1 3 0x80001f888074336938f74f7c5a00000000 "neutg" "neutg" NULL .1.3.6.1.6.3.10.1.1.3 0xf965e4ab0f35eebb3f0e3b30\
6bc0797c025821c5 .1.3.6.1.6.3.10.1.2.4 0xe277044beccd9991d70144c4c8f4b672 0x
usmUser 1 3 0x80001f888074336938f74f7c5a00000000 "myuser" "myuser" NULL .1.3.6.1.6.3.10.1.1.2 0x2223c2d00758353b7c3076\

setserialno 1424757026
So if you do not see any usmUser it's probably that your badly added your users.
The soluce
sudo /usr/local/sbin/snmpd -c /var/net-snmp/snmpd.conf -c /usr/local/share/snmp/snmpd.conf
I need a way of tracking downloads by users of my site, for mp3 files in my cloud storage? Aside from storage logs, are there any other solutions.
There's a storage logging feature: https://cloud.google.com/storage/docs/access-logs
This question is pretty old, but I thought I would share my solution in case anyone is looking for a solution still. You need to enable access logs and then write some scriptage to download and parse the access logs.
I used Ruby and here's the meat of my script:
#!/usr/bin/env ruby
require 'fileutils'
temp_dir = "/tmp/access-logs"
output_file = "/tmp/download-count.csv"
# Clean up the existing access logs
FileUtils.rm_rf(temp_dir)
FileUtils.mkdir(temp_dir)
`/usr/bin/gsutil -m cp "gs://my_access_logs/FusionAuthAccesssLog_usage_*" #{temp_dir} > /dev/null 2>&1`
# Collect the counts
counts = Hash.new(0)
Dir.foreach(temp_dir) do |file|
if File.file?("#{temp_dir}/#{file}")
date = file.gsub(/MyAccesssLog_usage_([0-9]{4})_([0-9]{2})_([0-9]{2}).*/, '\1\2\3')
File.readlines("#{temp_dir}/#{file}").each do |l|
if l =~ /my-file.zip"/
counts[date] = counts[date] + 1
end
end
end
end
File.open(output_file, "w", :encoding => "UTF-8") do |f|
# Write the header
f.puts("Date,Download count\n")
# Write the counts
counts.sort.each do |date,count|
f.puts("#{date},#{count}\n")
end
end
I wrote a blog post on this that goes over the script in detail as well. Here's the link: https://fusionauth.io/blog/2018/09/20/download-counts-from-google-cloud-storage
I'm migrating some shell scripts to Chef recipes. Some of these scripts are fairly involved, so just to make life easier in the short term and to avoid introducing bugs in rewriting everything in Chef/Ruby, I'd like to just run some of them as-is. They're all well-written and idempotent, so honestly there's no rush, but of course, the eventual goal is to rewrite them.
One cool feature of Ruby is its __END__ keyword/method: Lines below __END__ will not be executed. Those lines will be available via the special filehandle DATA.
It would be cool to ship the shell scripts as-is inside the the recipe after __END__, maybe something like the following, which I placed in chef-repo/cookbooks/ruby-data-test/recipes/default.rb:
file = Tempfile.new(File.basename(__FILE__))
file << DATA.read
bash file.path
file.unlink
__END__
echo "Hello, world"
However when I run this (with chef-solo -c solo.rb --override-runlist 'recipe[ruby-data-test]'), I get the following error:
[2014-10-03T17:14:56+00:00] ERROR: uninitialized constant Chef::Recipe::DATA
I'm pretty new to Chef, but I'm guessing the above is something about Chef wrapping my recipe in a class, and there's something simple preventing me from accessing DATA. Since it's "global" (?) I tried putting a dollar sign ($DATA) in front of it but that failed with:
NoMethodError
-------------
undefined method `read' for nil:NilClass
So the question is: How do I access DATA in my Chef recipe? Thanks!
It appears you don't have access to DATA, but you can fake it by reading in the current file yourself and splitting on __END__, like Sinatra does.
I ended up making a Chef LWRP for reuse. I don't know if I'll actually end up using this, but I wanted to figure it out. Like I said, I'm a Chef/Ruby noob, so any better ideas or suggestions welcome!

I am writing a plugin to check authentication to a https site and then search for a text in the response html,body to confirm successful login. I have created the following plugin
#!/bin/bash
add_uri='--no-check-certificate https://'
end_uri='/'
result=$(wget -O- $add_uri$1$end_uri --post-data=$2)
flag=`echo $result|awk '{print match($0,"QC Domain")}'`;
echo $flag
echo "Nagios refreshes properly1"
if [[ $flag -gt 0 ]] ; then
echo 'ALL SEEMS FINE!!'
exit 0
else
echo 'Some Problem'
exit 2
fi;
When I execute this plugin directly from command line
./check_nhttps <url here> '<very long post data with credential information>'
The plugin works as expected(For both + & - test cases) and there seems to be no issues.
But when the plugin runs from Nagios,
check_command check_nhttps! <url here> '<very long post data with credential information>'
It always shows critical error(Prints else condition text "Some Problem" too).
P.S : Tried sending the post data with double quotes also.
Please help!!!
I'd think its very probable that your post data contains some characters that confuse nagios, maybe a space, or even a !. Better put the post data into some file and use --post-file. Also, you might insert echo "$2" > /tmp/this_is_my_post_data_when_executed_by_nagios into your script and check if the post data is ok.
I have two VOD servers (RTSP) each on a different machine in a local network at home (vlc and Darwin streaming server).
What i am trying to do is a performance test that goes as follows:
* send in 10 requests, 50, then 100.
* redo the same but request multiple files instead of emulating multiple access to a single file.
* output statistics (speed, quality...etc).
What i have right now is OpenRstp which uses "-Q" to output Qos info but it is nowhere near what i need.
What i need is a free tool that can help me with this...all the ones i found (divesifeye and IxLoad) are not free.
Could anyone please suggest something useful?
I found a method that should do. It is based on openRTSP with "-Q" for Qos statistics.
the trick is how to redirect the data to a file as the Qos info only shows up after the feed is cut off. i wrote the following script to manage N-readings of a video feed/playlist. It will create a file that will contain the Qos info.
#!/bin/bash
f_rtsp(){
clear
echo -e "ENTER THE NUMBER OF STREAM USERS:"
echo -n "USER:"
read usr
for((i=1; i <= $usr;i++))
do
exec &> /$HOME/Desktop/results
echo -e "******************************* $i *****************************"
openRTSP -Q rtsp://<url>/<playlist-name>.sdp &
done
}
