[CentOS] Can not get remote X connections to work on CentOS 4.1
I've encountered a strange problem in CentOS 4.1. I've never had this problem before, and I've been using X Windows since 1990, but I can't get remote X connections to work: $ hostname host00 $ echo $DISPLAY :0.0 $ xhost + access control disabled, clients can connect from any host $ rsh host01 $ xdpyinfo -d host00:0.0 xdpyinfo: unable to open display "host00:0.0" Both hosts are running CentOS 4.1 and SELinux is disabled. I know I can get this to wok with ssh, but that is not the point. Also, it's not a host name resolution problem, as substituting the IP address in the above command gives the same error. Finally, note that there is about a 3-4 second delay before the error message appears. Any recent changes in X that I am unaware of? Alfred
