Hi Murray, some time ago we had a similar / the same problem induced by gdm (2.20). In the sources of gdm (gdm-net.c) is a hard coded value for MAX_CONNECTIONS. When we faced the problem, we found out that the value was set to a quite small value (may be 5 or so) in the specific Ubuntu release we used. We had to recompile gdm from source with MAX_CONNECTIONS=100 to solve the issue. cu Carsten _______________________________________________ SunRay-Users mailing list [email protected] http://www.filibeto.org/mailman/listinfo/sunray-users
