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?
