NWW TCP/IP Overview 95
Gateways
Gateways (routers) are used to connect networks together. Gateways are
devices that act as translators between systems that do not use the same
communication protocols, data formatting, structures, languages, or
architectures. Gateways repackage the data packets and change the syntax to
match that of the destination system. When networks are divided into subnets,
gateways are required to connect one subnet to another.
Default Gateway
The Default Gateway is the gateway or router that, if not specified, will be
used to move packets between networks. It is specified by an IP address.
If multiple gateways or routers exist, then the default gateway is typically the
address of the first, or nearest, gateway or router. If no gateways or routers
exist, then the default gateway will typically assume the IP address of the
network node (such as the workstation or HP Jetdirect projector server).
Syslog Server
A syslog server is a system on the network (typically a UNIX system) that can
receive and log syslog messages from other devices on the network. Syslog
messages allow administrators to monitor status or troubleshoot network
devices.
A syslog server requires software that provides syslog capabilities running on
the server. UNIX systems provide a daemon, syslogd, that monitors User
Datagram Protocol (UDP) port 514 for incoming messages. The messages are
processed depending on their priority and on how syslogd is set up to operate.
You can configure the HP Jetdirect projector server with the syslog server’s
IP address. When a syslog server is configured, both the HP Jetdirect projector
server and attached device can send syslog messages using UDP.
