You mean "xhost +". "xhost +frontend" would be better, but that's a
horribly insecure technique and should only be used if you trust every
other device on your network *and* you've given up on making SSH's X
tunneling work properly. And even then, you should run "xhost -" on
backend to close the hole once you're done.
(Hopefully this wouldn't even work; hopefully backend would be
running a packet filter "firewall" that would block incoming
connection attempts to TCP/6000 *and* would run X11 on Unix sockets
instead of TCP sockets. Doug, are you really running a distro whose
X server listens for TCP connections?)
