Work Related to Analysis and Development

Web Services

Warren continued to work on web services. He attended a PPDG conference call to discuss web services. Warren also continued to work on user authentication using X509 certificates.

Warren also discussed how to web services could be useful with the team working on setting up a resource broker.


There is a new PingER site at CAIA at Swinburne University in Australia.

Les is reviewing the beacon sites. He cleaned up some troublesome PingER beacon hosts (Waikato, Spain) and is trying to get ping access to a host in Bombay. He also discussed setting up monitoring at Stanford medical school.

Les looked at the transoceanic links used by PingER are like for Sally Floyd.


Warren discussed setting up IEPM-BW target sites with contacts at University of Utah and University of Michigan. Les and Jerrod worked with someone in the Czech Republic to set up an IEPM-BW remote site. Les is also working with UIUC to get an IEPM-BW remote host there.

Les talked to Richard Hughes-Jones in order to get web space for the monitoring at Manchester. Les is also looking into ssh problems at IN2P3, JLab and working with BNL to get a new host to monitor.

Les is conducting a survey from I2 E2E folks on the iepm-bw toolkit/installation at their site.

Les worked with Connie and Paola to get a real time display of throughput from the IEPM-BW bandwidth tests. Les worked with Connie to get the bandwidth tests to work in flood mode, i.e. run all tetsts simultaneously.

Les is working with Sylvain Ravot of Caltech (stationed at CERN) to see how high throughput we can get from CERN to SLAC. Warren implemented some patches at SLAC.

Les worked with Rice and LANL put together an INCITE poster submission for the DoE SciDAC booth at SC2002.

Les exchanged emails with Rob Thomas concerning his DNS monitoring page.

Les worked on the networking panel for SC2002.


Les worked with Paola, Jiri, Jerrod and Anthony from NIKHEF to get demos ready for iGrid2002 and to get access to the iepm-bw remote hosts from iGrid2002.


Les is evaluating the new Beluga ping/traceroute monitoring tool from CAIDA.


Warren reinstalled Antonia and the modified web100-enabled kernel following tips from the web100 discussion list to attempt to make Antonia more stable.


Warren repaired a problem with the AMP machine by replacing the hard drive sent from SDSC. Warren upgrade the IPEX machine by replacing the hard drive sent from Telcordia.

Warren installed and configured two machines (Hebe and Iphicles) ready for SC2002.

Plus the usual troubleshooting and maintenance headaches.
