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...
