Display X apps on remote host problem

[dv]

I'm having a problem displaying X apps on a remote host.    I've done this
plenty of times before but for some reason I can't get it today, I must be
forgetting something.   On the remote host, I ran "xhost +" to allow
everyone access to the X server over the network.   On the host I want to
run the X apps from, I ran "export DISPLAY=remotehostname:0.0".   When I
try to start an X client, I get an error about not being able to open the
display.   Neither server has iptables running.


root at remotehost:~> xhost +
access control disabled, clients can connect from any host

root at tux root# export DISPLAY=192.168.1.61:0.0
root at tux root# xeyes
Error: Can't open display: 192.168.1.61:0.0
