Johari has set up a web landing site for the Malaysian collaboration. It is at http://pinger.unimas.my/pinger. It contains:
Items already available from the website are:
To do for the website:
Please visit the website, any feedback, corrections, suggestions are much appreciated.
It would help to have an MoU between SLAC and UTM. Based on DOE current MOU policy, using the UNIMAS MOU format will not work. SLAC's legal folks also do not think that merely adding additional parties to the current MOU will work either. The new DOE policy will require a new approval. We may be able to get DOE approval of a Work for Others agreement. To do a WFO agreement we would need, at a minimum:
Assuming we can get these issues addressed, our legal folks think we could seek DOE approval and enter into an agreement with these other universities. We need to hear back from UTM and UM whether we need/want to pursue this further. It will probably be a considerable effort. UTM & UM will need to address 1. We all need to think about 3. 4 is easy, 2 is doable, 7 and 8 are tricky.
Johari recommended a future PingER workshop later this year. This time it would be in a Peninsular Malaysia site hosted at either UTM or UM. Hanan at UTM has agreed to take the lead. We need to get 4 or 5 universities involved. It looks like it will be the week of June 24-29 at University of Malaya. For exact date, will decide at the end of the month after discussing with Abdullah and Johari.
Will Anjum and Kashif attend, they will need funding, is funding available? Les will need funding. What about Bebo? Update Hanan?
Johari has submitted a proposal for FRGS (Fundamental Research Grant Scheme). We hope to hear more in April. We can go for a bigger project such as the eScience or LRGS (Long-term Research Grant Scheme) which can accommodate a larger number of people, more funding and encourage cross institutions collaboration. As for research, we need to clarify a few matters:
The Next step in funding is to go for bigger research fund, such as LRGS or eScience. We can use the upcoming workshop (1 specific session) to brainstorm and come up with such proposal. need to do some groundwork before that as well.
Anjum mentioned a paper on Evaluation of IP Geolocation Algorithms on PingER and PlanetLab Infrastructures, by Fida Gilani et. al. submitted to IEEE INFOCOM 2011UNIMAS. This could be updated with new data and maybe submitted to a different venue. Anjum forwarded a copy of the paper to Johari, Abdullah and Hanan with copies to the team. The idea is to see whether there is interest at UTM, UM or UNIMAS.
There is a problem with the UNIMAS traceroute. It appears pinger.unimas.my is behind a NAT that is not passing the traceroute UDP probes. Other hosts at UNIMAS are not seeing the problem, so Johari believes it may have to do with the IPTABLES in pinger.unimas.my. Traceroute using the -I option (send the probes using ICMP rather than UDP) seems to work (but needs root access). Thus it would appear not to be in the return (ICMP "time exceeded") response. The probes (when not using the -I option are UDP packets using sequentially ports 33434 - 33465 for up to 30 hops). It is possible that ports > some number may be blocked. Update Johari, Anjum.
Johari has set up a guest account for Anjum. Anjum logged on and reported some concerns about addresses and interfaces not matching. The traceroute/ping server is important for the TULIP trilateration project and also understanding routing within and from Malaysia.
The UTM Pinger site is http://pinger.fsksm.utm.my/cgi-bin/ping_data.pl to get the data. .
The traceroute server is also running. It is at: http://pinger.fsksm.utm.my/cgi-bin/traceroute.pl. Saqib discovered the problem was a timeout in traceroute.pl. Saqib has extended the timeout and it works better. There may still be timeout problems and Saqib will experiment with longer timeouts of up to 280ms.
Saqib is starting to look at Pingtable.pl anomalies as a start in a case study for Malaysia and S.E Asia.
We should discuss:
It is not easy to find such sites in those states. Obvious targets are universities, for example UUM in Kedah and UNIMAP in Perlis, but those sites are not ping-able. One way is to approach these universities and explain to them about PingER project and request for the ping packet to be enable. Les has sent HostFinder.pl to Johari to possibly assist in finding hosts.
Dr Nor Badrul Anuar Jumaat has installedl PingER on a cloud at UM. The machines are virtualized and running Ubuntu Linux.UTM & UM will need to address 1 The name and address of the server is pinger.fsktm.um.edu.my (202.185.107.238). The UM monitoring host has been added to the NODELIST PingER meta data base at SLAC and the <HostList> for Malaysian and S.E Asian hosts has been added to the pinger.xml file at UM. We need to get the latest pinger2.pl installed. Since the traceroute is working, "we" can start to make a routing study similar to https://confluence.slac.stanford.edu/display/IEPM/Routing+from+UNIMAS. Badrul has a student who will be working on the case study and will coordinate with Saqib at UTM and Johari at UNIMAS to combine results and to put together a paper for the Malaysian ISI Journal probably around the end of June
Raja is waiting for the Letter of Support from NUST after which he will mail the documents for SEVIS ID process. (3/20/2013).
Arshad and the NUST Rector were to visit UM and UTM earlier this week. However, this fell through due the Rector being sick.
Since the number of monitoring nodes in Malaysia is likely to grow, I think it is a good idea to start thinking of automated ways of synchronizing the <HostList> section. A few thoughts on this matter:
With Malaysia moving quickly to IPv6 (already Nava at USM has sent Les an IPv6 address that he recommends monitoring), converting PingER (especially the gathering, analysis) work with IPv6 is an interesting problem. Anjum believes he could provide an undergraduate to start on this. SLAC looks like it may be getting some traction to enable IPv6 on a some subnets. SLAC has an official Provider Indpendent IPV6 address space and are putting together a small project. We will start with the site web server and email.
(1) Creative visualization of PINGer data including rich interaction;
(2) Publication of PINGer data in Linked Open Data formats thereby increasing its usefulness to other researchers.
If these are of interest, Bebo is willing to work with students who come to SLAC and remotely with students at UNIMAS and NUST. Bebo believes that both of these areas have great potential for papers within the conference communities with which he is directly involved.
With PingER going back over a decade, its presentation tools tend to be a bit jaded having in some cases been developed in the 90's. New, modern ways to access display and navigate the data would be a big plus.
Build and install a new http://www-iepm.slac.stanford.edu/pinger/tools/pingER-2.0.2.tar.gz file with the improved version of pinger2.pl
The annual report to the International Committee for Future Accelerators (ICFA) Standing Committee on Inter-regional Connectivity (SCIC) has also been completed. Les has been invited to give a general colloquiam at SLAC on the Internet where it came from, challenges and how it is performing. the latter section will report some PingER case studies and measurements.
Raja is experimenting with using different alpha values as well as different target landmarks in Europe, America and Pakistan. So far the results of using a constant alpha value and variable alpha values based on RTT are quite similar. I am trying to find the conditions and situations under which using variable alpha values is better. (3/20/2013).
Raja has completed the MATLAB script and used it to generate some input files for Pakistan and Europe. However using the alpha values (function of both region and RTT value) found through the alpha analysis the distances were underestimates in some cases. He is working on finding the cause and possible solution. Did you get an answer?
Next meeting Wednesday ? 2013 9:00pm Pacific Daylight Time, Thursday ? 2013 9:00am Pakistan time, Thursday ? 2013 12:00 noon Malaysian time.
