• "Since we're still waiting on an account, at SLAC, I asked the student to explore another idea (which is quite relevant) proposed by Prof. Bebo “Creative visualization of PingER data, including rich interaction;”. He has already started looking at the possible attractive/interactive design, at the same time he is working to improve his programming skills."

• There is another student, (Jaafrau) has a design.  Looking at visualization.

• 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.
  

• 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.

• Email 6/15/2016 to Fitzi, pinger.fsksm.utm.my is down.

NUST

• Currently it does not respond to ping pingerqta.pern.edu.pk 
  • Ping 121.52.157.148, responds

  • • 271cottrell@pinger:~$ping pingerqta.pern.edu.pk
      ping: unknown host pingerqta.pern.edu.pk

    • [cottrell@pinger ~]$ nslookup pingerqta.pern.edu.pk

  • http://121.52.157.148, responds with the default Apache web page
  • http:http://121.52.157.148/ Apache responds. http://121.52.157.148//cgi-bin/ping_data.pl? responds (albeit very slowly) with Get Ping Data from sharedw228.b2bhosting.net  Also there is data. 
    • This is a funny hostname. It comes from the system response to the perl commands:

      • use Net::Domain qw(hostname hostfqdn hostdomain);
        my $hostname = hostfqdn();

  • The following needs to reflect the new IP address at 121.52.157.148. It is very easy to change the IP address once the Measurement Agent is up and running and responding, in fact the PingER meta data at SLAC was changed in February 2015. Howeer However the DNS still points to:Address:

    • Output from: /bin/cat /etc/hosts
       # Do not remove the following line, or various programs
       # that require network functionality will fail.

    •  fail. 127.0.0.1 localhost.localdomain localhost 121.52.157.157 pingerqta.pern.edu.pk

     

  Following hosts are down and not responsive. Nodes were contacted many times for identifying their issues. i.e turn on their pinGER Computers but never responded well.

  ...
