I recommend you start by installing the attached known-good config. files included in the document.
Put these file in their "standard" location:
/etc/uucp on recent
linux distributions or
/usr/lib/uucp on older ones.
Then make sure that the
permissions of the files are
(guylhem@barberouge:uucp)$ ls -l total 11 -rw-r--r-- 1 uucp uucp 501 Jan 23 11:33 Poll -rw-r----- 1 uucp uucp 589 Jan 23 11:34 call -rw-r----- 1 uucp uucp 1184 Jan 23 12:06 config -rw-r----- 1 uucp uucp 476 Jan 23 12:31 crontab -rw-r----- 1 uucp uucp 1256 Jan 23 11:47 dial -rw-r----- 1 uucp uucp 486 Jan 23 11:48 passwd -rw-r----- 1 uucp uucp 810 Jan 23 11:55 port -rw-r--r-- 1 uucp uucp 1690 Jan 23 12:04 sys (guylhem@barberouge:uucp)$
To change file owner, as root, type:
(root@barberouge:uucp)$ chown uucp.uucp *
Then you must change file permissions; as root once again, type:
(root@barberouge:uucp)# chmod 640 * (root@barberouge:uucp)# chmod +r Poll sys
This file is used to set polling timetables for any system.
schedule polux 01 poll polux 01
My machine calls polux at 01:00, that's all!
You can add more line if you must call many other machines, but don't forget to put the 2 lines (schedule & poll) for each.
It contains your login/password for each system you poll:
polux uudan password
My machine uses "uudan" login & "password" password :-) when it polls "polux".
As for Poll, adapt this to your situation.

Here just replace "barberouge" by your system name ; run "hostname" if you can't remind it.

Just run "crontab -u uucp /etc/uucp/crontab" to add it to the others crontabs.

Syntax is complicated ... you'd rather not touch anything here but "ATZ" & "ATX4" which are my modem init string.
If you allow uucp dialin, just add system/passwords in this file.
It's *that* simple.
But it's recommended for security reasons to make sure each have a separate account & home directory so you can track things.
# Description for the modem entry # Debianers, make SURE this device is root:dialout, mode 0660 (crw-rw---) port ACU type modem device /dev/ttyS0 dialer hayes speed 57600 # hardflow n # Description for the TCP port - pretty trivial.

You shouldn't change anything here ... except your modem port.
On recent distributions with mgetty, it's
/dev/ttySN while on older
/dev/cuaN, where N is you serial port:
N starts at 0 & ttyS(N) means COM(N+1), for example, my null-modem is on ttyS1 (COM2) while my modem is on ttyS0 (COM1).
Most of recent modems support hardware flow control, if your doesn't, just uncomment the line "# hardflow n".

Here, you must change "polux" by the name of the system you poll & "0111111110" by its phone number.
"polux-2", "polux-tcp" & "horizon" are just examples of user specific needs ; if the system you poll has more than one line, define it as "itsname-2" ; if you call it by PPP sometimes, just define "itsname-tcp" also.
It's useful when chat script fail (busy ...)

to check if all the informations you've set are correct.
Warning: your mileage may vary ; different distributions use different paths, regardless Linux FSSTD!
If everything is correct, run:
/usr/sbin/uucico -r 1 -x 9 -s remote_system_name
-x 9 will have maximum debugging information written to the
/var/log/uucp/debug file for help in initial setup.
I normally run
-x 4 here since that level logs details that help me
with login problems.
Obviously, this text contains clear informations from your systems file
(account/password) so protect it against world-read.
>From Pierre.Beyssac at emeraude.syseca.fr
Taylor has more logging levels. Use -x all to get the highest level possible.
Also, do a
"tail -f /var/log/uucp/debug" while debugging to watch
things happen on the fly.
