Howdy All I have a very weird issue. Im running a 4.8 Release box as a NIS client and for every process that either logs in or changes running as user a Listening UDP port is created. Im putting some sample output from ps sockstat and lsof to show what I mean. The problem is these UDP ports are listening ports bound to all interfaces. It appears to be releated to NIS because when i uncomment the +::::(etc) from the passwd and group files it goes away for any newly started processes. I dont even have to turn off ypbind. Ive tried to put ypbind in secure mode and well as non broadcast mode and the same results happen. Any ideas as to what this is? More importantly, any idea of how to get rid of it?
