UUCP CONFIGURATION

• CASE 1 : UUCP CONFIGURATION FOR A NEW CLIENT
  • UUCP configuration is to be carried out at Starcom's public server, the mail server of the client and the MX record of that domain name
  • Consider that we have to add both incoming and outgoing queues for the domain name xyz.org
  • Carry out the following steps
  • On Starcom's public server
    1. Edit the file /etc/mail/virtusertable.txt and append the entry
       • @xyz.org uucp-dom:inmail.xyz.org
    2. Execute the following command
       
       • makemap hash /etc/mail/virtusertable.db < /etc/mail/virtusertable.txt
    3. Edit the file /etc/uucp/sys and add the entries for the incoming and the outgoing queues
       • system inmail.xyz.org
         myname uucp-in1.pub.starcomsoftware.com
         called-login inmail.xyz.org
         time any
         commands rmail

         system outmail.xyz.org
         myname uucp-out1.pub.starcomsoftware.com
         called-login outmail.xyz.org
         time any
         commands rmail

       • If you want to configure only one queue then make the respective entry for the incoming or the outgoing queue as per the specification
       • Edit the file /etc/uucp/passwd and add the following entry
         • inmail.xyz.org xyz_passwd
         • This represent a space separated queuename and its respective password which will be used while configuring the client uucp.

    
    

  • On Client Mail server
    1. Edit the file /etc/uucp/sys and add the entries
       • system uucp-in1.pub.starcomsoftware.com
         myname inmail.xyz.org
         port type tcp
         address uucp-in1.pub.starcomsoftware.com
         chat ogin: inmail.xyz.org word: xyz_passwd
         time any
         chat-timeout 500
         protocol-parameter t timeout 500

         system uucp-out1.pub.starcomsoftware.com
         myname outmail.xyz.org
         port type tcp
         address uucp-out1.pub.starcomsoftware.com
         chat ogin: outmail.xyz.org word: cawoswa123
         time any
         chat-timeout 500
         protocol-parameter t timeout 500

    2. edit the file /usr/lib/uucp/uusched as user uucp and make the entry
       • ping -c2 uucp-in1.pub.starcomsoftware.com >/dev/null 2>&1
         /usr/lib/uucp/uucico -r1 -S uucp-in1.pub.starcomsoftware.com &

         ping -c2 uucp-out1.pub.starcomsoftware.com >/dev/null 2>&1
         /usr/lib/uucp/uucico -r1 -S uucp-out1.pub.starcomsoftware.com &

    3. Add the following entry in the crontab of the uucp user
       • 0-59/5 * * * * /usr/lib/uucp/uusched
    4. Point the mx of the xyz.org to pub1.starcomsoftware.com. For this the changes are to be made to the client's DNS Hosting Server
    5. Stop sendmail
       • /etc/init.d/sendmail stop
    6. Edit the file /etc/mail/local-host-names and add the entry
       • xyz.org
    7. Start sendmail
       • /etc/init.d/sendmail start

    
    

  • On Starcom's public server
    • Stop sendmail
      • /etc/init.d/sendmail stop
    • Edit the file /etc/mail/local-host-names and add the entry
      • xyz.org
    • Start sendmail
      • /etc/init.d/sendmail start

    
    

  • Testing of UUCP configuration
    • On the client mail server execute the following command
      • telnet uucp-in1.pub.starcomsoftware.com 540
      • Login :
      • Password :
      • Enter the login name and password as per the specification in the /etc/uucp/passwd file on the public server
      • If login is allowed then quit as the uucp port can accept connections form the client mail server
    • Test mail from public server to client mail server address
    • Send test mail from saurabh@gmail.com to xyz@xyz.org via telnet from public server and trace it in the logs /var/adm/log/mail.log.
    • The mailer in the logs for the sendmail entry should be uucp-dom:inmail.xyz.org
    • On the client side in order to verify proper transfer of mail execute the following command after the interval of 5 minutes
      • uustat -m
    • The logs of uucp conversations are
      • /var/log/uucp/Log
      • /var/log/uucp/Stats

  
  

• CASE 2 : UUCP CONFIGURATION FOR AN ALREADY EXISTING UUCP CLIENT BUT FOR A NEW DOMAIN
  • Consider the scenario where in you already have a uucp mail delivery configured for domain xyz.org
  • Now the client wants that the mails coming for abc.org should also be delivered to the mail server that recieves mail for xyz.org
  • In order to do that carry out the following configuration
  • Point the mx of the xyz.org to pub1.starcomsoftware.com. For this the changes are to be made to the client's DNS Hosting Server
  • On Starcom's public server
    • Edit the file /etc/mail/virtusertable.txt and append the entry
      • @abc.org uucp-dom:inmail.xyz.org
    • Execute the following command
      
      • makemap hash /etc/mail/virtusertable.db < /etc/mail/virtusertable.txt
  • On Client's Mail Server
    • Stop sendmail
      • /etc/init.d/sendmail stop
    • Edit the file /etc/mail/local-host-names and add the entry
      • xyz.org
    • Start sendmail
      • /etc/init.d/sendmail start
  • On Starcom's public server
    • Stop sendmail
      • /etc/init.d/sendmail stop
    • Edit the file /etc/mail/local-host-names and add the entry
      • xyz.org
    • Start sendmail
      • /etc/init.d/sendmail start
  • Carry out the testing as described in the first case.
