Package: ntp
Version: 1:4.2.0a-5
Severity: wishlist
ntpq only shows numeric IP addresses in the "refid" field of the "peers"
output. This small patch makes it show human-friendly hostnames,
but respects the "-n" option to show IP addresses if desired.
Example of output without this patch:

The NTP specification says that a refid is a "32-bit code", which is what the
IP address represents. So resolving this to a host name would be
semantically wrong.
