The first two lines print out the number of seconds that the name server
has been running and the number of seconds since the last restart
caused by a SIGHUP signal. To convert these values to days, divide by
86,400 (the number of seconds in a day).
input packets is the number of datagrams received by the name server.
The datagrams come from the resolver code compiled into the services
and from queries and responses from other name servers.
output packets is the number of datagrams sent by the name server.
These datagrams are responses to resolver queries, responses to queries
from other name servers, and system queries. Because queries to other
name servers may not be answered, there will probably be more output
packets than input packets.
queries is the number of queries received by this name server. Because
the name server can handle datagram and stream connections, there can
be more queries than input packets. The total number of queries is the
sum of all the counts of different query types listed in this statistics
