ROUTE - You can use
the route command line tool to display the current IP
routing table and add or delete IP routes.
[-p] [command] [destination] [MASK netmask] [gateway]
[METRIC metric] [IF interface]
-f - Clears
the routing tables of all gateway entries. If this is used
in conjunction with one of the commands, the tables are
cleared prior to running the command.
-p - When
used with the ADD command, makes a route persistent across
boots of the system. By default, routes are not preserved
when the system is restarted. Ignored for all other
commands, which always affect the appropriate persistent
Prints a route.
ADD - Adds
Deletes a route.
Modifies an existing route.
destination - Specifies the host.
- Specifies that the next parameter is the 'netmask' value.
Specifies a subnet mask value for this route entry. If not
specified, it defaults to 255.255.255.255.
- Specifices the interface number for the specified route.
Specifies the metric, ie. cost for the destination.
All symbolic names used for destination are looked up in the
network database file NETWORKS. The symbolic names for
gateway are looked up in the host name database file HOSTS.
If the command is PRINT or DELETE, destination or gateway
can be a wildcard (wildcard is specified as a star '*'), or
the gateway argument may be omitted.
If Dest contains a * or ?, it is treated as a shell pattern,
and only matching destination routes are printed. The '*'
matches any string, and '?' matches any one char. Examples:
157.*.1, 157.*, 127.*, *224*.
Invalid MASK generates an error; that is, when (DEST & MASK)
route ADD 184.108.40.206 MASK 220.127.116.11 18.104.22.168 IF 1
The route addition failed: The specified mask parameter is
invalid. (Destination & Mask) != Destination.
route ADD 22.214.171.124 MASK 255.0.0.0 126.96.36.199 METRIC 3 IF 2
destination^ ^mask ^gateway
If IF is not given, it tries to find the best interface for
a given gateway.
route PRINT 112* .... Only prints those matching 112*
route CHANGE 188.8.131.52 MASK 255.0.0.0 184.108.40.206 METRIC 2 IF
CHANGE is used to modify gateway and/or metric only.
HOSTNAME - Hostname is used to show the local
computer's host name for authentication by the Remote Copy
Protocol (RCP), Remote Shell (RSH), and Remote Execution
TRACERT - Tracert is
sometimes used to verify that IP addressing has been
correctly configured on a client. It will basically show the
route taken to reach a remote system.
Usage: tracert [-d] [-h
maximum_hops] [-j host-list] [-w timeout] target_name
-d - Do not
resolve addresses to hostnames.
-h maximum_hops - Maximum number of hops to search for target.
-j host-list - Loose source route along host-list.
- -w timeout - Wait timeout milliseconds for each reply.
