This is certainly possible to do for any dynamic linked application. I think it wouldn't work for static linked ones. Currently I don't know if I have to face such application on the project I am on. The reason why I am not so a big fan is that using the LD_PRELOAD trick seems very hackish to me. As Glauber has argumented in this thread, there are properly quite a few people who want to control or monitor sockets. It seems I am one of those. Having this kind of support in cgroups seems like a very neat solution to me. thanks, daniel _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
