= ping does not work on thinclient =
ping command did not work on thinclients, but on host debian it works.
We examined the promblem, then we found that /bin/ping did not have suid bit.
Why did ping work on host debian? Because /bin/ping had `cap_net_raw+p` capability.
Thinclients used NFS, so capability was not referred.

Our solution is removing libcap2, and `dpkg-statoverride --update --add root root 4755 /bin/ping`.

BTW, mozc does not work...
