Absurd as it may sound at the first moment, using UUCP to transfer data
|
|
over TCP not that bad an idea, especially when transferring large
|
|
amount of data such as Usenet news. On TCP-based links, news is
|
|
generally exchanged using the NNTP protocol, where articles are
|
|
requested and sent individually, without compression or any other
|
|
optimization. Although adequate for large sites with several concurrent
|
|
news-feeds, this technique is very unfavorable for small sites that
|
|
receive their news over a slow connection such as ISDN. These sites
|
|
will usually want to combine the qualities of TCP with the advantages of
|
|
sending news in large batches, which can be compressed and thus
|
|
transferred with very low overhead. A standard way to transfer these
|
|
batches is to use UUCP over TCP.
|
|
<P>
|
|
In sys, you would specify a system to be called via TCP
|
|
in the following way:
|
|
<P>
|
|
<P><P>
|
|
<P>
|
|
The address command gives the IP address of the host, or its
|
|
fully qualified domain name. The corresponding port entry would
|
|
read:
|
|
<P>
|
|
<P><P>
|
|
<P>
|
|
The entry states that a TCP connection should be used when a sys
|
|
entry references tcp-conn, and that uucico should
|
|
attempt to connect to the TCP network port 540 on the remote host. This
|
|
is the default port number of the UUCP service. Instead of the port
|
|
number, you may also give a symbolic port name to the service
|
|
command. The port number corresponding to this name will be looked up
|
|
in /etc/services. The common name for the UUCP service is
|
|
uucpd.
