Hmmm, It seems as if 'xhost' needs to do a nameserver query before it will report anything? For some reason (probably self inflicted) every time I now issue the command 'xhost' it hangs for quite a while, then will report the list. I have (for the time being) blocked many things at the FW, one of which is port 53; therefore, I can see the requests getting blocked each time I issue the command. Is there any way around this? I do have a /etc/hosts entry for the client, and the client is the only one I added via 'xhost +client'. Yet it still wanders off to the nameservers. -Mike
