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:

They  fixed one problem by registering pingeramit.on and changing:

<SrcName>pingeramity.amitynoida.local</SrcName>
to
<SrcName>pingeramity.in</SrcName> 
 in /usr/local/share/pinger/pinger.xml

...

They fixed up a  strangeness in the DNS lookup for pingeramity.in as seen from SLAC that was causing problems with gathering data:

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

Non-authoritative answer:
Name: pingeramity.in
Address: 202.12.103.71
Name: pingeramity.in
Address: 173.193.105.245

The host has been un-pingable for the last two days. They have been experiencing Ethernet problems that they hope to solve in the coming day. Then we will retest.

They will look at setting the REMOTE_ADDR environment variable.

  • A method is being tested where Perl is compiled on Android and pinger2.pl involving Root access and Busybox installation
  • Another method of modifying the output from the standard ping command is also being worked on
  • There have been some irregularities in the output saved on the device running the app mentioned on github. Both the data and a few noted irregularities have been attached
  • It has also been noted that the standard Notepad provided on Windows machines is not ideal for viewing such data (using something like gVim, 010 Editor, EmEditor, etc would be better)
  • Regex Patterns have been tried to capture appropriate values from a given string. A There is a  document containing these patterns has been attached.
  • Parsing of output of ping commands has been attempted. The ideal case conversion of the command "ping -s 100 -c 10 yahoo.com" results in the following. Please acknowledge if it is in the correct format. More information is attached in the document titled "Basic Ping Output Conversion.docx"
