4. Setting up the config files

I recommend you start by installing the attached known-good config. files included in the document.

4.1 Installing config. files

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

4.2 "Poll" file

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.

4.3 "call" file

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.

4.4 "config" file

nodename barberouge                     # The UUCP name of this system

spool /var/spool/uucp                   # The UUCP spool directory
pubdir /var/spool/uucppublic            # The UUCP public directory
logfile /var/log/uucp/log               # The UUCP log file
statfile /var/log/uucp/stats            # The UUCP statistics file
debugfile /var/log/uucp/debug           # The UUCP debugging file

#sysfile        /etc/uucp/sys           # Default "sys"
#portfile       /etc/uucp/port          # Default "port"
#dialfile       /etc/uucp/dial          # Default "dial"
#dialcodefile   /etc/uucp/dialcode      # Default "dialcode"
#callfile       /etc/uucp/call          # Default "call"
#passwdfile     /etc/uucp/passwd        # Default "passwd"

# No commands may be executed by unknowns (empty list of permitted commands)
# Upload is authorized in /var/spool/uucp
unknown commands
unknown pubdir /var/spool/uucp
unknown remote-send ~ !~/upload
unknown remote-receive ~/upload

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

4.5 "crontab" file

# Every day just before morning generate reports.
#
0 7 * * *     /usr/lib/uucp/uudemon.day root
#
# Every hour start the uudemon.hr. To actually poll a remote system,
# enter its name in /etc/uucp/Poll. You are encouraged to change the "8".
#
8 * * * *      /usr/lib/uucp/uudemon.hr

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

4.6 "dial" file

# 1) expect nothing (i.e., continue with step 2)
# 2) send "ATZ", then a carriage return, then sleep for 1 to 2 seconds.
# The \c means to not send a final carriage return.
# 3) wait until the modem echoes "OK", then do the the same for "ATX4" & "OK"
# 4) send "ATDT", then the telephone number (after translating any dialcodes).
# 5) wait until the modem echoes "CONNECT"
# 6) if we get "BUSY", "NO CARRIER" ... during the chat script we abort dialing
# 7) when the call is over, we make sure we hangup the modem


dialer hayes
chat "" ATZ\r\d\c OK\r \dATX4\r\d\c OK\r ATDT\D CONNECT
chat-fail RING
chat-fail NO\sCARRIER
chat-fail ERROR
chat-fail NO\sDIALTONE
chat-fail BUSY
chat-fail NO\sANSWER
chat-fail VOICE
complete \d\d+++\d\dATH\r\c
abort \d\d+++\d\dATH\r\c

# You can also add other dialers: inetd, nullmodem ...
#dialer nullmodem
#complete \d\dexit\r\c
#abort \d\dexit\r\c

Syntax is complicated ... you'd rather not touch anything here but "ATZ" & "ATX4" which are my modem init string.

4.7 "passwd" file

#uuguest                guestpassword

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.

4.8 "port" file

# 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. DON'T DELETE.
# Change service number if non standard, cf /etc/services

port TCP
type tcp
#service 540


# Description for the nullmodem entry
# (ttyS1 means COM2)

port nullmodem
type direct
device /dev/ttyS1
dialer nullmodem
speed 115200

You shouldn't change anything here ... except your modem port.

On recent distributions with mgetty, it's /dev/ttySN while on older distributions it's /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".

4.9 "sys" file

# First some defaults. These are for ALL other entries (unless overridden).
#
protocol gvG
protocol-parameter G packet-size 1024
# protocol-parameter G window 7
protocol-parameter G short-packets

#
# Our remote uucp connection.
#
system polux
call-login *
call-password *
local-send /
local-receive /var/spool/uucppublic
remote-send /
remote-receive /var/spool/uucppublic
time any
phone 0111111110
port ACU
chat "" \r\c ogin:-BREAK-ogin:-BREAK- \L word: \P
#chat "" \d\d\r\c ogin: \d\L word: \P

# This is an alternate - it means that if a connection using the above
# "system polux" fails it falls through to this entry.
# Only useful if your service provider has more then one phone number for UUCP.
#
#alternate polux-2
#alias polux-2
#phone 0222222220

# Here's another alternate - we poll the system over TCP/IP.
# This is useful if we have a PPP connection to our provider.
# The first two entries will fail because the modem is busy & we will poll
# over TCP/IP.
#
#alternate polux-tcp
#alias polux-tcp
#time any
#address uucp.polux
#port TCP
#protocol t

#
# Last example - a system that we poll over TCP/IP.
#
#system horizon
#call-login *
#call-password *
#time any
#chat "" \d\d\r\c ogin: \d\L word: \P
#address uucp.horizon.nl
#port TCP
#protocol t

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 ...)

 For protocol G will use the following parameters
  packet-size 1024
  short-packets

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

The -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.

4.11 Additional informations

>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.
