XWindows locks when xhosting to Solaris from linux

Hello,

When xhosting from my Redhat 8.0 Linux
Box to a SUN Sparc 50 running Solaris 7
MOTIF or GUI program lock-up the
network. By running network restart,
sometimes I can recover, but often the
X-server locks up and I need to reboot
my Linux box.

I seem to vaguely remember a bug in SUN
XWindows that causes such a problem, but
I'm having trouble finding references or
work arounds. Any info would be very
appreciated.

Thanks
Jason

Never heard, but then Solaris 7 is pretty old, I'd
upgrade to 8 or even better 9, if possible.

Usually you can recover from a X lockup by
switching to console and kill the offending app
or changing the runlevel, enabling magic sysreq
or login remote from another box.

Xhost is *very* insecure; even in the old days it was considered too
risky for anything but testing. So somebody could be fooling with
you. Use a better X authentication method. For example, if the
solaris/7 host is running sshd suitably configured, simply go in an
xterm and launch "ssh -X user@solarishost". Then in the xterm "xclock &"
would be a quick way to check that it's working.

You might have been able to login remotely to clear the console
without rebooting by killing the X server.

There's a mention in the Cygwin FAQ that Solaris X apps in 24-bpp mode
don't get along with XFree86. They suggest trying 16 or 32 bpp.
