Xnest from x.org

[Alex Kapranoff]

Good day!

I'm trying to run Xnest (nested X server) from x.org and getting core
dumps with the following message:

capella:~[0]% Xnest :1
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/capella.domain.ru:1
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
zsh: segmentation fault (core dumped)  Xnest :1

Do I need IPv6 to run it, does anyone know? That :1 is the desired display
number, by the way.

I use:
FreeBSD 5.3-STABLE #0: Wed Nov 10 13:26:32 MSK 2004
xorg-nestserver-6.7.0
xorg-server-6.7.0_9
