If you are talking about "/opt/ssh/utils/ssh_chroot_setup.sh", yes,
I've used this script to init chroot directory, which is /adamroot in
my test.

So there are two nsswitch.conf files at /adamroot/etc/ and /etc/.
I changed "ipnodes" in "/etc/nsswitch.conf", removing "nds" part. 
Meantime, "ipnodes" in "/adamroot/etc/nsswitch.conf" as the default
value, "nds nis file".  I also had the tunneling problem in this
scenario.

Here's another interesting part.  If I put nds at the beginning of
ipnodes, tunneling will be OK.  But if I put either of other two
methods at the beginning, but still have dns behind, I will still has
this problem.  Looks that even the order of "resolve from" will affect
the results.  

If "dns nis files" passed, why just something like "files dns nis"
should failed?
