users at your site.
uuep occasionally sends mail about minor problems to "uucp" or "root". Your maintenance
person should also read and toss these messages. You can redirect the mail to your mailbox by
putting an entry for "uucp" in /u,r/lib/alia,e,. Look at the examples there.
Under normal conditions, uuep calls your designated sites at specified times and, while it's at it,
checks to see if anything should come back. If you ever need to invoke uuep 'on command', the
line:
:/I:
/usr/lib/uucp/uucico -rl -s,itename
forces uuep to poll ,itenamf:, even if there is nothing waiting. If you do run uuep in this fashion,
don't run it as super-user, since the suid* bit will not be honored. If you are having trouble with
the connection, run uuep with the debugging option, as described in installation step 7, below.
6.4.1. UUCP
Installation Overview
A uuep network link using modems or dedicated lines may be established between two machines
running
UNIX
systems. To establish a connection between two sites that both have modems,
one site must have (at least) an automatic call unit (an auto-dial modem) and the other must
have (at least) a dialup port (an auto-answer modem). It is better if both sites have one of each
or, as is standard, have modems which both call and answer, like Ventel's.
If both you and the site(s) you wish to connect with have autodial units and ports, install
uuep
as follows. If you have only a dialup your situation will be different; procedures are described
near the end of this section. For more information, read the VueI' Implementation De,eription
in the final section of this manual. It describes in detail the file formats and conventions, and
will give you necessary context.
1. Select a site name (less than 8 characters): the name of the machine which will be your
uuep connection to the outside world. We will call this machine your 'uuep host'; its name
is your 'uuep hostname ' .
If this machine is your "main machine" (see Setting VI' the Mail Syltem, above), then your
uuep hostname should be the same as your domain name.
2. Change the / u,r/ ,pool/ uuep/ D.noname directory to your own site's
/u,r/'pool/uuep/D.ho,tname directory with the following:
:/I:
mv /usr/spool/uucp/D.noname /usr/spool/uucp/D.holtname
Use your uuep hostname for ho,tname.
3. Create a uuep account in the password file on your uuep host machine by entering a line of
the following form in / etcl pa"wd:
Uholtname:.:4.:4:::/usr/spool/uucp:/usr/lib/uuep/uueieo
Now use the pa"wd command to establish a password for your host:
*
pa.sswd Uho,tname
• "suid" stands for "set user i.d."; if you set this bit on an executable file,
UNIX
will grant or deny
file access based on the permissions of the file's owner, rather than the permissions of the person
who executes the file. Uuep uses this facility to ensure that all the files in its spool directories are
readable and write able no matter who invokes the uuep program.
