Hello everyone, in order to facilitate my xrootd developments I have started to write a wireshark dissector for the xrootd protocol. It enables me to see in a quite nice way what is happening on the wire. It is still quite incomplete, but may be of some use to you too. http://ljanyst.web.cern.ch/ljanyst/smietnik/snapshot3.png http://ljanyst.web.cern.ch/ljanyst/smietnik/snapshot4.png The source: http://cern.ch/ljanyst/repos/xrootd-wireshark.git Cheers, Lukasz
