288 BLACK BOX ® Advanced Console Server
The Routing Table
The BLACK BOX ® Advanced Console Server has a static routing table that can be seen using
the commands:
route
or
netstat -rn
The file /etc/network/st_routes is the BLACK BOX ® Advanced Console Server’s method for
configuring static routes. Routes should be added to the file (which is a script run when the
BLACK BOX ® Advanced Console Server is initialized) or at the prompt (for temporary
routes) using the following syntax:
route [add|del] [-net|-host] target netmask nt_msk [gw gt_way]
interf
[add|del] One of these tags must be present
.Routes can be either added or deleted.
[-net|-host] Net is for routes to a network and -host is for routes to a single host.
target Target is the IP address of the destination host or network.
netmask
nt_msk
The tag netmask and nt_mask are necessary only when subnetting is used,
otherwise, a mask appropriate to the target is assumed. nt_msk must be
specified in dot notation.
gw gt_way Specifies a gateway, when applicable. gt_way is the IP address or hostname
of the gateway.
interf The interface to use for this route. Must be specified if a gateway is not.
When a gateway is specified, the operating system determines which inter-
face is to be used.
