Package: x2goagent Version: 3.5.0.32 As discussed with IONIC, there is a problem when You try to connect to different servers from Windows at the same time, using multiple instances of x2go client. The reason is, that the x2go servers are all using the same SSH_Port. That should not be a problem from my point of view, so that behaviour should be further investigated. The problem was reported already a very long time ago, but still exists : https://www.mail-archive.com/x2go-user@lists.berlios.de/msg00547.html In the meantime, here a small patch for x2gostartagent script: That patch uses a different SSH_PORT for each Server, therefore try to avoid conflicts. There are two methods implemented : method one, suitable for Class "C" Networks, with no possible conflicts. The SSH Port is dependent on the last octet of the servers host adress. method two, with randomized ports, what may lead to conflicts from case to case, but can handle networks were servers might have the same last octet of the host adress. However, that patch enables to have multiple instances of x2goclients running on one windows machine, against different hosts. please find attached the IRC conversation log with Ionic, as well as the patched script for x2gostartagent I hove it can be committed, I am getting tired to patch my hosts on every x2go server update ;-) yours sincerely Robert Nowotny Rotek GmbH
