- INSTALLING UUCP ON A WIN-TCP NETWORK
-
- Here's how to set up UUCP over WIN-TCP between two NCR System 3000's.
-
- To install UUCP on a WIN-TCP network, you must perform these general steps:
-
- * Configure your system's listener process to accept calls from remote systems
-
- * Modify your system's UUCP administrative files to call remote systems
-
- * Configure the remote system's listener process to accept calls from
- your system
-
- * Modify the remote system's UUCP administrative files to call your system
-
- If you require login/password security under UUCP, you must also perform
- these general steps:
-
- * Add a login name on your system into which each remote system's
- UUCP can log in.
-
- * Add a login name on each remote system into which your system's UUCP
- can log in.
-
- For best performance, you must set up both your system and each remote system
- in complementary fashion. Configure your system configured to call each remote
- system; set up each remote system to call your system.
-
-
- Before setting up UUCP, you must:
-
- * Know your system's node name. (Hint: type "uname -n".)
-
- * Know the node name of each remote system you wish to contact.
- (Type "uname -n" on each remote system.)
-
- * Be sure that WIN-TCP communication with the remote system exists,
- for example, rlogin or telnet connects to the remote system.
-
- * Decide if you want UUCP to use login/password protection.
- Before creating a UUCP network with login/password protection,
- decide which login and password you will assign to each remote system's
- UUCP. Likewise, ask the administrator of each
- remote system to assign your system's UUCP a login and password.
-
- * Login to your system with super-user privileges
-
- You are then ready to start setting up UUCP over WIN-TCP.
-
- SET UP YOUR SYSTEM'S LISTENER PROCESS
- Set up your local listener process using steps 1 through 8.
- The procedure takes into account the possibility that your listener has
- already been configured.
-
- 1) Create and initialize the files needed by the network listener by typing:
-
- nlsadmin -i tcp
-
- If your listener has not already been initialized, the command displays
- no message. Otherwise, the command displays the message:
-
- nlsadmin: error: Listener already initialized
-
- Disregard the message if it appears.
-
- 2) Determine your system's Internet Protocol address and port number
- by typing:
-
- IPADDRESS=`/usr/etc/rfsaddr -h\`uname -n\``
-
- If an error message appears, it implies a problem in the WIN-TCP
- configuration itself.
- You won't be able to continue setting up UUCP until WIN-TCP is corrected.
-
- Display your system's Internet and port address by typing:
-
- echo $IPADDRESS
-
- The result will be a hexadecimal string similar to:
-
- \x00020ace874f6ca6
-
- Save this string since you will need it when setting up remote systems
- to call your system.
-
- 3) Assign the address and port to your listener by typing:
-
- nlsadmin -l $IPADDRESS tcp
-
- The command displays no message on successful completion.
-
-
- If you want to install your UUCP listener with login/password protection,
- go to step 5, otherwise continue with step 4.
-
- 4) Add an unsecure listener service by typing:
-
- nlsadmin -a 101 -c "/usr/lib/uucp/uucico -r0 -iTLI -unuucp" \
- -y "uucp listener" tcp
-
-
- If the service already exists, you will see the message:
-
- nlsadmin: error: Service code already exists
-
- If the message appears, ignore it.
-
- Skip to step 9.
-
- 5) Add a secure listener service by typing
-
- pmadm -a -fu -ptcp -s101 -iroot -v`nlsadmin -V` \
- -m`nlsadmin -c/bin/login -ptirdwr` -y "uucp network login"
-
- If you have already set up the service, you may see the message:
-
- Invalid request, 101 already exists under tcp
-
- 6) Add a network login for each remote system that will call into your
- system, by typing:
-
- passmgmt -a -h /var/spool/uucppublic -s /usr/lib/uucp/uucico \
- -c "UUCP network login" <UUCP login>
-
- where <UUCP login> is the login name you chose for the remote system.
- Some administrators assign names like "xuucp" where `x' is the first
- letter of the remote system name.
-
- Note: The standard UUCP network login "nuucp" comes installed on your system.
- Although you may let more than one system use the same UUCP network login
- (e.g. nuucp), you may prefer to give each remote system its own login
- for greater security.
-
- 7) Add a password for each network login by typing:
-
- passwd <UUCP login>
-
- The passwd command will prompt you to type and re-type the password which
- you wish to assign to <UUCP login>.
-
- 8) Using your favorite editor, at the top of your system's
- /etc/uucp/Permissions file, add a line similar to:
-
- LOGNAME=<UUCP login> MACHINE=<sysname> VALIDATE=<sysname>
-
- where,
- <UUCP login> is the login name you chose for the remote system, and
- <sysname> is the name of the remote system
-
- For each remote system which must login to your system,
- repeat steps 6 through 8.
-
-
- 9 ) Make sure your system's listener process has started by typing:
-
- nlsadmin -s tcp
-
- You may see the message:
-
- nlsadmin: error: Listener already running
-
-
- MODIFY YOUR SYSTEM'S UUCP ADMINISTRATIVE FILES FOR CALLS OVER WIN-TCP
-
- 10) Using your favorite editor, verify that the file /etc/uucp/Dialers contains
- the line:
-
- tcp "" "" NLPS:000:001:101\N\c
-
- anywhere in the file. If the line does not exist, or has been commented out by
- a `#' character, add the line exactly as shown.
-
- 11) Using your favorite editor, verify that the file /etc/uucp/Devices contains
- the lines:
-
- TCP,eg tcp - - TLI \D tcp
- TCPS,eg tcp - Any TLIS \D tcp
-
- anywhere in the file. If the lines do not exist, or have been commented out by
- a `#' character, add the lines exactly as shown.
-
- 12) Using your favorite editor, verify that the file /etc/uucp/Devconfig
- contains a line
-
- service=uucico device=TCPS push=tirdwr
-
- anywhere in the file. If the line does not exist, or has been
- commented out by a `#' character, add the line exactly as shown.
-
-
- MODIFY YOUR UUCP SYSTEMS FILE FOR EACH SYSTEM YOU WISH TO CALL
-
- 13) Determine the remote system's listener's Internet address and port string.
-
- If the remote system's listener has not been set up, set it up now by
- performing steps 1 through 9 on the remote machine as appropriate.
- The goal is to configure the remote system's listener's address from step 2,
- when performed on the remote system, into your system.
-
- If the remote system's listener has been set up, determine its
- Internet address by typing the following command ON THE REMOTE SYSTEM:
-
- nlsadmin -l - tcp
-
- This value you obtain is called <IP address> in the following step.
-
- 14) Add an entry for the remote system into your system's /etc/uucp/Systems
- file using your favorite editor.
-
- If the remote system has login/password security, add a line like
-
- <sysname> Any TCPS - <IP address> ogin: <UUCP login>\n\c ssword: <password>\n\c
-
- Note the \n\c sequence following the <UUCP login> and <password>.
-
- where,
- <sysname> is the remote system's name
- <IP address> is the Internet address and default port string
- <UUCP login> is the name under which your system's UUCP logs
- into the remote system
- <password> is your system's UUCP login password on the remote
-
- If the remote system does not nave login/password security, add a line like
-
- <sysname> Any TCP - <IP address>
-
- where,
- <sysname> is the remote system's name
- <IP address> is the Internet address and port
-
-
- Repeat steps 13 and 14 for each remote system which your system calls.
-
-
- SET UP EACH REMOTE SYSTEM TO RECOGNIZE YOUR SYSTEM
- Setting up systems for UUCP is complementary.
- You must set up each remote system to which your
- system connects to recognize your system. Do this by repeating
- the steps 1 through 14, as appropriate, on each remote system.
-
- TESTING THE UUCP CONNECTION OVER WIN-TCP
- After setting up the machines in your network, test out
- your UUCP connection to another system with a debugging trace.
- Type in:
-
- /usr/lib/uucp/Uutry -r <sysname>
-
- where <sysname> is the name of a remote system.
-
- A successful trace using login/password protection looks like this:
-
- /usr/lib/uucp/uucico -r1 -s<sysname> -f -x5 >/tmp/<sysname> 2>&1&
- tmp=/tmp/<sysname>
- force flag set (ignoring uucico limit)
- mchFind called (<sysname>)
- attempting to open /var/uucp/.Admin/account
- mkdir - /var/spool/uucp/<sysname>
- Job grade to process -
- conn(<sysname>)
- Trying entry from '/etc/uucp/Systems' - device type TCPS.
- Device Type TCPS wanted
- Trying device entry 'tcp' from '/etc/uucp/Devices'.
- processdev: calling setdevcfg(uucico, TCPS)
- Internal caller type TLIS
- tlicall: bound to
- t_connect to addr "\x00020ace884e7d8c"
- set interface TLIS
- tssetup: MASTER mode: leaving ok
- pop_push: PUSHing tirdwr
- gdial(tcp) called
- Trying caller script 'tcp' from '/etc/uucp/Dialers'.

-
- Be sure to initiate the connection between other machines and your own system.
- Key in the same command on a remote system specifying your system's name
- as <sysname>.
-
- If both traces succeed, you have basic assurance that you will be
- able to transfer files and even e-mail.
