PingER MA - Les

Installation Overview.This is proceeding. They have a working pinger2.pl. They have a public DNS pingeramity.it. They have installed ping_data.pl, it is working however:

 

They  have changed from
<SrcName>pingeramity.amitynoida.local</SrcName>
to
<SrcName>pingeramity.in</SrcName> 
 in /usr/local/share/pinger/pinger.xml

There is information on progress at Setting up PingER servers at Amity.

There is now something strange in the DNS lookup for pingeramity.in as seen from SLAC that is causing problems with gathering data:

[cottrell@pinger ~]$ nslookup pingeramity.in
Server: 134.79.111.111
Address: 134.79.111.111#53

Traceroute/ping servers - Les

http://202.12.103.71/cgi-bin/traceroute.pl  gives “the web page below:

However clicking on Yes gives:

I.e. the target address is a private Internet address (RFC 1918).  One gets a similar result for http://202.12.103.71/cgi-bin/traceroute.pl?function=ping

This is at least partially due to the host's environment variable REMOTE_ADDR=10.0.253.1 whereas it should be the public address of the remote host but. 10.0.253.1 is a private address so here is no way to traceroute to it

Android implementation of Pinger Measurement Agent - Bebo

Old Information

Student availability

There are two students (Jahin and Ankit Singh)  will be at at the University of Florida who have F1 US visas and will finish at Florida in the 1st week in May. They are then free to come directly to SLAC. They will then continue their studies in the US in August 2016, hence they will be available at SLAC for ~ 3 months. Low cost housing could be an issue. Most of the other students are BTech students at Amity who will graduate in May.  Once we have their names and mutual interest we can start the paper work to get started on invitations. Aditya Pan and Anwesha Mal who graduate in May with a BTech are going to the National University of Singapore. (I am unsure if this  means they are going to University of Singapore after they graduate in May, or before then. Are they candidates to come to SLAC?)

PingER students

The following have written papers on PingER:

  • Aditya Pan has started work on the Android port of the PingER MA
  • Anwesha has started work on looking at the PinGER data and using cluster analysis on it
  • Jahin and Aditya have started work on looking at the PingER data and correlation analysis

Les has copies of these three and has reviewed the Android and cluster analysis papers.  It would help if he could be provided with a copy in word so he could mark up corrections before they go to publication via IEEE.  These students will be working remotely with Les and Bebo at SLAC between now and May.
