networkNDS
Minutes
Keith Carsten Kipp Warren Stuart John Z Duncan Josh Brian Adam Patrick Filipo Announcements: The face to face meeting is now set. We will develop and circulate the agenda over the next week. networkNDS: John started by summarizing the need for something that could serve data in a secure way outside the control room. John has followed on with Ben's ideas about this and now has a lot of code written for it. John is trying to work out the ideas behind authentication, but is not sure yet how this is going to work out. There was significant discussion of this authentication, use of ssl or just using a method similar to the ext cvs method. Patrick asked about how big this would need to be scaled? John said there is no back of the envelope on this yet. He assumed that the greatest use of this would be in the context of commissioning and data charaterization. Stuart thinks that any whoping machine can saturate the bandwidth into or out of the site. So he thinks that this is going to be naturally throttled by the network connection. Josh asked about the steps for release of LIGODB for the broader collaboration. He asked about when there would be a new service for pointing to. Being able to do this is dependent on John having time to get it working. Stuart said that there could be a replica NDS server. There is a necessary protocol change to support the authorization and authentication. Duncan asked about where the NDS protocol is written down. Stuart said there were limitations in the original protocols which will need improvements. John agreed that it is a good idea to try to describe what the protocol is right now, then develop requirements, then extend it. Patrick asked that John would move this forward by putting things on paper to get everybody together to talk about it and make a plan for the future. Josh asked about the client tools who would be writing and maintaining the code base for client. Keith mentioned that dataviewer (C), DTT/DMT (C++), ligoviewer (TCL), ligoDB (matlab), dbcommand (C), Ben's c-library, miniNDS. Patrick summarized that this seems like a real opportunity for us to streamline some of our software by making this better. Patrick suggestted John then will make sure that all the right people can get this started this week. Josh asked if we could put the current NDS onto a new machine and use ssh tunneling. Stuart has already talked to Rolf about trying it. It's not just a matter of standing up a box and going. How to get the data from framebuilder to proxy server. Josh is going to start a document which asked What is the publication mechanism into this service? Update on CentOS 5.0: Adam reported that he is going to re-build the EPEL lscsoft from Adam this afternoon. Duncan is continuing with the test release of Condor on SUGAR. So far it looks good.
