UUCP is nothing more then a file transfer protocol. Nowadays it's
7
mostly used to transfer offline mail and news. Most documentation
8
for it is in the manual pages and in the info files installed in
11
The Debian UUCP package is configured to use the taylor UUCP style
12
configuration files. While these files are more readable then the
13
"standard" HDB (Honey-Danber) configuration files there's less
14
documentation on it. However the config files supplied in /etc/uucp
15
are easy to setup. More elaborate exampes can be found in
16
/usr/share/doc/uucp/examples/taylor.
18
This package can also use the HDB configuration files instead of
19
taylor if you really want that. Examples for that can be found
20
in /usr/share/doc/uucp/examples/hdb.

1. FILE AND DIRECTORY LOCATIONS.
24
These might be a bit different then you're used to, so here's an overview:
26
/etc/uucp Configuration files
27
/usr/bin Programs to be executed by users
28
/usr/sbin Programs to be executed by root or uucp
29
/usr/lib/uucp Internal programs for the UUCP system, generally
30
not to be executed directly
31
/var/spool/uucp UUCP spool directory
32
/var/spool/uucppublic Public UUCP directory
33
/var/log/uucp Logfile directory
35
The most outstanding differences with "traditional" systems are that the
36
logfiles are not in /var/spool/uucp, uucico is in /usr/sbin instead of
37
/usr/lib/uucp and the configuration files are in /etc/uucp instead of
38
also in /usr/lib/uucp.

2. SETTING UP A SIMPLE LEAF SITE.
42
a. Get a UUCP name from your provider, and a loginname and a password.
43
Also ask for the provider's UUCP name and the telephone number.
44
b. Enter your providers UUCP name, loginname and password into /etc/uucp/call
45
c. If the UUCP name you got is not the same as your systems hostname,
46
edit /etc/uucp/config and set the nodename to your systems UUCP name.
47
d. Enter the device your modem is connected to in /etc/uucp/port
48
e. Make an entry with the UUCP name of your provider in /etc/uucp/sys
50
If you are using a /dev/ttyS device (for example, /dev/ttyS1) to dialout
51
on, set the modes on /dev/ttyS1 to 660 and chgrp it to the "dialout" group.
52
That way, uucico (the file transfer engine) can access that port.
54
The same is true if you use a /dev/cua device but the permissions should
55
already be OK. (Use of the cua* ports is deprecated however).
57
Now you should be able to place a call to your provider and login
58
successfully with the command "uupoll <provider_uucp_name>". Beware
59
that if there are any mail messages for you and you have not setup
60
your mail system correctly that you might lose those messages.
64
3. MAINTENANCE AND POLLING THE OTHER SYSTEM AUTOMATICALLY.
66
You can add the uucp name, and a list of hours when you want your system
67
to call the providers UUCP system to the file /etc/uucp/Poll. This file
68
is examined hourly by the /usr/lib/uucp/uudemon.hr script to see if
69
the remote system(s) should be polled.
71
uudemon.hr is called from uucp's crontab in /etc/cron.d. Job expiry is
72
started from the /etc/cron.daily/uucp script. See /etc/uucp/expire. Logs
73
are rotated with logrotate.
77
4. DEBIAN SPECIFIC PATCHES/BEHAVIOUR
79
* In port commands \H is substituted with the address assoziated with the
80
system. That allows you to use the same port (for instance an ssh port) for
83
* uucico supports a --grade option that limits outgoing call to a given grade.
85
* In order to have /etc/uucp root.uucp, i.e. not writeable by the uucp
86
processes, it may be necessary that you start uucp related programs like
87
uucico as user uucp. For instance sudo -u uucp uucico... .
