Installation & Service Manual
The Routing Table
The Cyclades-TS has a static routing table that can be seen using the commands
route
or
netstat -rn
The file /etc/network/st_routes shown in Figure 6.5 is the Cyclades-TS’s method for configuring static routes.
Routes should be added to the file (which is a script run when the Cyclades-TS 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 a 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 interface is to be used.
ssh - The Secure Shell Session
ssh is a command interface and protocol often used by network administrators to connect securely to a remote
computer. ssh replaces its non-secure counterpart rsh and rlogin. There are two versions of the protocol, ssh
and ssh2. The Cyclades-TS offers both.
