Topher is here for a few days. He and Bebo discussed whether it would be better to use native Android tools rather than loading the perl interpreter and using it.
- Pro: easier for user, no need to load perl interpreter which may require missing skills, especially for a non technical user
- Con: the android version has to mimic pinger2.pl with all its logs, careful checking and specific format
To a large extent it depend on how we plan to use this. If the phones are just MAs in a fixed location then 1 is easier and probably sufficient. If this is intended to grow into a mobile application for general use then it needs to be 2.
We agreed that Sara Masood at UUM should continue pursuing using the standard pinger2.pl version running under the perl interpreter while Amity will try and put together a native android version.
We also briefly discussed how to get the data from the phone MA to the archive. The current method ping_data.pl requires a public IP address for the phone which mnay not exist if its is mobile. Getting the MA to put the data to the archive may raise some security issue for the archiver. We did ot come to a conclusion

Bebo has set up a Github codebase as a new project. It contains the PingER MA (pinger2.pl and the traceroute/ping server). Anyone needs to sign up for a Github account (if you don't already have one), so you can be added as a project member.
- slac-pinger/pinger created by topherwhite. PingER project https://github.com/slac-pinger/pinger
- Now we have it we can share with Amity to check it works.
- Bebo reports that someone from Amity requested to be a member of the Android group.

From Adib:
Adib asked a student (Jaafrau) to explore “Creative visualization of PingER data, including rich interaction;”. He has come up with a good design, yet the development part needs a lot of work. Adib will ask him to upload his interface and share the link.
Adib has a student from Thailand who is working with Adib at UUM who may be interested in installaing a PIngER MA in Thailand. Adib will talk next week after exams to see if can get permissions. 8/3/2016: No update yet, as they have a long holiday in Thailand. Will try to contact him.
Adib has written a case study on the Internet performance in ASEAN countries and its implication on the Socio-Economic Indexes. It has been shared with Dr.Les and Prof. Bebo who have commented. We are looking for where to publish.

pinger.unimas.my is working again as of ~ June 18th, also teh the traceroute server is working.

- Sara Masood - pingER monitoring host on android .
- She is using perl-android-apk Interpreter to run perl on android. It includes execution of 3 perl scripts:
- getdata.pl, ping_data.pl, pinger2.pl
First step is to install pre-requisite i.e. lynx, perl, XML::Simple, make etc. However, she is was having permission denied issue when she executes "make install” command at path usr/local/bin because it’s a read only file system. She is searching for the solution but maybe needs to change the path to /data/local/tmp.
Step 2 Is to execute ping _data and cgi-bin, traceroute.pl <http://traceroute.pl/>
- Step 3: To execute pinger2.pl <
Perl-android-interpreter application was depreciated so install perl package using GNURoot Debian Application
"Make install" issue is resolved too it create directorys and files required by pinger2 in usr/local/share/pinger
But now when i execute pinger2.pl <

getting data) using IP address its generating two errors image is attached. IP address is also updated in pinger.xml
First error is," cannot exec DnsV4Cmd.pl, file not found", but DnsV4Cmd.pl is in PingER directory with execute permission.
- Second error, "SrcIP could not be determined for DNS 203.124.57.137. Without the results produced by PINGER2 is not usable.".
- Les suspects the second error is result of the 1st error. maybe using the perl -d debugger would assist.
Step 2 Is to execute ping _data and cgi-bin, traceroute.pl <http://traceroute.pl/>
Step 3: To execute pinger2.pl <http://pinger2.pl/> that will start gathering data
Saqib will proceed to install Pinger in UAF Pakistan 6/22/2016.There used to be an MA at UAF Les will send the information to Saqib. it is below:

UTM
Saqib's old supervisor agreed to appoint a master student to take of PingER in UTM. Saqib has emailed 3/9/2016, no progress 4/6/2016, no progress 5/18/2016.

2. For the M.Sc. student in UTM we have to request again to Prof Hanan and Prof Asri and we need support from Prof Johari.
Given there is a working MYREN host at UTM, we wll give up on this.

"I have come up with initial proposed solution model. This model consists of several parts. The upper parts of the Figure below shows the data source, in which PingER data will be convert into RDF format. Then the data pre-processor will take care of converting RDF/XML into N-triples serialization formats using N-triples convertor module. This N-triple file of an RDF graph will be as an input and stores the triples in storage as a key value pair using MapReduce jobs"
Potential projects

Perl-android-interpreter is not executing .pl file mainly because old Perl version (Perl 5.10) which is not comparable with android lollipop 5.0 version, i am compiling Perl .5.22.0 for android ,it may solve issue.
