TITLE    : Setting up a dial out PPP connection
OS LEVEL : AIX 4.x
DATE     : 20/05/99
VERSION  : 1.2

----------------------------------------------------------------------------
In the example below the system will dial the freeserve number and logon 
as user rs6000.freeserve.co.uk with the password of mypassword :-

1, Check that the Async Point to Point Protocol software is installed :-

   lslpp -l bos.net.ppp

   If not installed, then install using smit install_latest

2, Create a tty to attach the modem to :-

   smit maktty
   select "tty rs232 Asynchronous Terminal"
   select the parent adapter

   a, fill in the port number
   b, select the baud rate required
   c, set the flow control to rts (RTS/CTS)
   d, leave all other options at their default values
   
3, Test the connection to the modem

   You need to have cu installed on the machine, check this using :-

   lslpp -L bos.net.uucp

   If not installed, then install using smit install_latest


   Edit the /etc/uucp/Devices file and append the following line :-

   Direct tty## - baud_rate direct

   Where tty## is the tty created in step 1, and baud_rate is baud
   rate number set for that tty.

   cu -ml /tty##

   "CONNECTED" should be displayed. Enter 'at'. The modem should respond 
   with "OK". You can enter a few at command to check the modem. Exit cu
   by entering a tilde (~) followed by a period (.)

4, Setting up PPP

   smit ppp
   select "Link Control Configuration"
   select "Add a Link Configuration"
   enter the following details :-

   a, PPP subsystem name         [ppp]
   b, max server connections     [0] 
   c, max client connections     [1]
   d, max demand connections     [0]
   e, max ip interfaces          [1]
   f, max async hdlc attachments [1]

   leave all other options at their default values 


5, Setting up PAP Authentication

   smit ppp
   select "PAP  Authentication"
   select "Add a User"
   enter the following details :-

   User name                     [rs6000.freeserve.co.uk]
   Remote host name              [*]
   Password                      [mypassword]

6, Start PPP using :-

   startsrc -s pppcontrold

   Check that the ppp control daemon is running using:-

   lssrc -s pppcontrold

   Check that the pp# network interfaces have been created using :-

   netstat -in

7, Setting up a debug file.
 
   In /etc/syslog.conf add the line :-

   *.debug /tmp/ppp

   Create the file /tmp/ppp using :-

   touch /tmp/ppp
   chmod +w /tmp/ppp

   Start debug using :-

   refresh -s syslogd

   pppcontrold can be set to provide more detailed output :-

   lssrc -s pppcontrold

   Note the process id (PID)

   kill -30 PID-of-pppcontrold

   This output can be switched off by :-

   kill -31 PID-of-pppcontrold

8, Create a "Chat script".

   -------------chat--script--starts--below--this--line--------------------
   ''
   atdt08450796699
   login:
   rs6000.freeserve.co.uk
   word:
   mypassword
   ------------chat--script--ends--above--this--line-----------------------

   Save this script as for example ppp-chat1

9, Establishing a connection.

   pppattchd is started to establish a PPP link. It calls the pppdial 
   program which uses the "chat script" to do the actual dial out. The 
   dial out command to use should resemble :-

   /usr/sbin/pppattached client multilink peer pap tty## connect \
   "/usr/sbin/pppdial -v -f ppp-chat1

   After issuing this command, watch the progression of the dial out by
   executing the following command :-

   tail -f /tmp/ppp
