urlcp settings control DNS (hostname resolution):
Takes a list of one or more search domains. Hostnames that do not
contain a dot are searched for in each of these domains, in order.
The default list is obtained from
/etc/resolv.conf or the
equivalent, depending on the system. Returns the previous list of
domains. The limit is 5 domains. Has no effect if
sys. Added in version 3.01.960500000 20000608.
Sets whether to ignore the TC (truncated message) flag in DNS
replies. This flag may be set by the name server if the reply is
too large to fit in one UDP packet and was truncated; a typical
cause of this is a hostname with many IP addresses, e.g. DNS-based
load management. Since only one IP is used from the reply, it is
safe to ignore this flag. On by default. Added in version
Sets the routines to use for domain name resolution. The 2nd
argument is either
int to use the internal (non-blocking)
sys to use the system's C library functions, or
(in version 3.01.993260000 20010622 and later),
which uses internal (non-blocking) routines unless no nameservers
can be found in which case the system C library functions are used.
Returns the previous setting. The default is
(Version 3.01.993260000 20010622 and earlier defaulted
int and had no
intsys setting.) In version
4.04.1068200000 20031106 and later, an empty string will
restore the default setting.
Note that the
sys routines are blocking and cannot be
nslookup; slow DNS
traffic may even cause the timeout to be exceeded. Also, certain
information and features of
be ignored if
sys mode is set, as well as other DNS-related
Sets whether to request recursion to other nameservers when
resolving hostnames. The default is on. Added in version
3.01.989630000 20010511. Returns previous setting.
Sets the initial retransmit interval (in seconds) for DNS lookups.
Has no effect if
sys. Default 5.
Sets the max number of retries for DNS lookups. Returns previous
setting. Has no effect if
sys. Default 4.
Takes a list of one or more of the strings
bind, indicating the name resolution services to use and
the order in which to try them. Returns previous setting.
Has no effect if
Sets the list of nameservers to use, in order, for DNS resolution.
Takes a list of dotted-decimal IP address strings, and returns the
previous list of nameservers. Has no effect if
