What is the status of the HEC report?

Sadia unearthed a problem in smokeping at SEECS. It has been fixed. She also unearthed a problem in table.pl which has also been Fixed. She also spotted differences in the stats reported by table.pl and pigntable.p that needed understanding. Well done Sadia in unearthing and reporting the problems.

Progress on ICFA Report 2011 - Zafar

...

I am still working on a monitor in Sarawak. It appears to be be usong Linuxselinux Linux selinux to block pings & traceroutes.

The new faster host for www-wanmon.slac.stanford.edu is up and running. It is 3-4 times faster for table.pl which now completes .instead of timing out

There is also a bug in the SEECS table.pl for dataservers with a @ sign for them, and the colors need to be looked at. Zafar is looking at.

...

With the move to the new host Faisal had to get a new cookie to allow scriptroute to run scripts on the PlanetLab infrastructure. Still needs testing.

Traceroute.pl versions earlier than 5.0 have XSS vulnerability. It has been fixed. Now needs to be downloaded and the new version installed

I have written a script (node-contacts.pl) to read the list of landmarks created by reflector.cgi then use an updated version of dbprac.pl to get contacts and dataserver from the database. Then extract the email addresses and using the CPAN sendmail.pm module be able to send an email to the contacts telling them of the need to upgrade. 

Traceroute

. I will leave the Pakistani landmarks to SEECS.

Get the MatLab license at SEECS and put up a CGB server using it. The student(Bilal) had exams, will resume work on Monday. Do not have license for MatLab will do on own machines to test and will migrate when have license. Zafar will contact Arshad and Ali. Basically the client will call the reflector with the target. The reflector will return the landmarks and RTTs*. Any progress on MatLab CBG - Zafar?*Versions earlier than 5.0 have XSS vulnerability. It has been fixed. Now needs to be downloaded and the new version installed

PerfSONAR

Zafar has not had a chance to do much work on it. The VMs are giving problems, changed to VMWare but no better. the machines are down. the graph problem is solved. Contacted Jason and pointed out problem with NTP servers. Latency nodes having problems. Working with NUST data center to sort out problems with VMs. Trying to fix the problem or move to physical. Zafar will put together paragraph on what has been working, plans and a picture.

  1. Faisal is working with Yee. Progress - Faisal
    1. Looking at how to display multiple nodes at a single lat/long or close lat/longs, a grouping problem. Looking at how to handle identical lat/longs. Looked at MonALISA, and other implementations. This has been solved. 
    2. Added Zoom in based on selection feature. User can select a specific region of a map by holding shift key and dragging through the bounds. Will add to the PingER maps.
    3. For displaying links b etween hosts, Faisal is using poly-lines to represent great circle routes, rather than just straight lines to present the actual shortest path. Lot of mathematical formulas. Study on implementing Bézier curves which may help better to separate paths.
    4. Representation of data in XML for links and paths. Writing an API so can get data from perfSONAR and provide to the client.
    Zafar found a problem in the TULIP map, Faisal has fixed it. Faisal has kept information on the landmarks used RTs etc, which be very valuable later to look at
    1. .
  2. Zafar - deploy PerfSONAR nodes at SEECS. Second step is to find whether the same can be done at HEC on PERN's network. It is working, congratulations! 

...

  1. Extend the NODEDETAILS data base to allow entry support for whether the host is currenty pingable.Get the MatLab license at SEECS and put up a CGB server using it. The student(Bilal) had exams, will resume work on Monday. Do not have license for MatLab will do on own machines to test and will migrate when have license. Zafar will contact Arshad and Ali. Basically the client will call the reflector with the target. The reflector will return the landmarks and RTTs. 
  2. Extend Checkdata to provide emails automatically, see https://confluence.slac.stanford.edu/display/IEPM/Extend+checkdata+to+make+it+more+useful  . Many of the ides in the script node-contacts.pl are a step in this direction.
  3. Add MOS and alpha to pingtable.pl see https://confluence.slac.stanford.edu/display/IEPM/Add+Mean+Opinion+Score+%28MOS%29+to+pingtable.pl+metrics  Sadia will start work on it when done with HEC report,  writing thesis. When should we expect progress?
  4. Improve the PingER2 installation procedures to make it more robust.  This might be something for the person(s) in Pakistan who are responsible for installing PingER2 at the Pakistani monitoring sites. They probably have found where the failures occurs. Also look at the FAQ, and ping_data.pl which has been improved to assist in debugging, could it be further improved (e.g. provide access to the httpd.conf file so one can see if it properly configured)? There are 2 students working on the PingER archive. Is this something they could work on?
  5. Fix PingER archiving/analysis package to be IPv6 conformant. Will build a proposal for an IPv6 testbed. They will try various transition techniques.   Any progress?

Future

Les is trying to clear space to visit SEECS in February.

Les has submitted the invitation letters for Amber and Sadia to SLAC management. They have have SLAC IDS. What is the status of the computer accounts?The account request have been received at SLAC, they will be submitted after Jan 3rd, 2011. Les also the has forms for Bilal's account, they will be submitted early next year.

They need to learn Perl. Zafar will go over what the projects PingER (this is done) and perfSONAR (this has to be done).  hope to do tomorrow after finish the HEC report).

Zafar has his  D2019. He has applied to the consulate, then await an interview with a weeks notice, then about a month to get visa. Hope for interview Dec 21st. optimistic, realistic late/Feb. Update

Adnan Kiani  has just been introduced to the PingER project. He completed his PhD degree this year in communications at Brunel University. He will be taking over the liaison at SEECS from Anjum. 

Arshad coming in Jan, to start his daughter at FotthillFoothill. Falsal looking for aplace a place for them
