Connecting Using a Terminal Server
or Concentrator
A terminal server can be a perfect compliment to IRC, particularly in a data-
center environment where servers are grouped in clusters. Through one terminal
server, a remote administrator can gain access to a number of different servers
either through a shared modem or through a local area network connection.
This topology greatly decreases or eliminates the need for multiple modems
and phone lines. This topology also provides another level of security since
access can be restricted to a trusted private network or a centralized remote
access server.

Figure 7-1. Typical terminal server topology
Figure 7-1 shows a typical terminal server topology. In such a configuration,
the terminal server is directly connected to the integrated serial ports on a
cluster of servers. The Integrated Remote Console feature of each server is
configured for direct-connect access through the selected integrated serial port.
Out-of-band access to any connected server can be obtained by establishing a
TELNET connection through the terminal server to the appropriate port.
