Public bug reported:

Description:    Ubuntu 22.04.3 LTS
Release:        22.04
Package Version: iputils-clockdiff 3:20211215-1

Expect to happen: Use clockdiff as an unprivileged user.

What happened instead: Basic functions are not available for
unprivileged users. When try to get the time difference between
localhost and a remote, clockdiff fails with an error message ”Operation
not permitted”.

clockdiff 185.125.190.21
clockdiff: nice: Operation not permitted

Problems: Clockdiff is configured with CAP_NET_RAW, but it is not
sufficient, CAP_SYS_NICE is needed as well. After add CAP_SYS_NICE as
root, the permission error is gone, but a "host is down" message is
returned. We think that might be a problem too.

clockdiff -o 39.156.66.18
clockdiff: 39.156.66.18 is down
