The +pppd(8) man page is the best reference for the full details; this file +outlines the configuration process for the most common case, where +this package is being used to enable a machine to dial an ISP and +connect to the internet. The FAQ and README.linux files also provide +useful information about setting up PPP. + +Dialling an ISP. +**************** + +Usually, an ISP will assign an IP address to your machine, and will +refuse to authenticate itself to you. Some ISPs require a username +and password to be entered before PPP service commences, while others +use PPP authentication (using either the PAP or CHAP protocols). + +The recommended way to set up to dial an ISP is for the system +administrator to create a file under /etc/ppp/peers, named for the ISP +that you will be dialling. For example, suppose the file is called +/etc/ppp/peers/isp. This file would contain something like this: + +cua0 # modem is connected to /dev/cua0 +38400 # run the serial port at 38400 baud +crtscts # use hardware flow control +noauth # don't require the ISP to authenticate itself +defaultroute # use the ISP as our default route +connect '/usr/sbin/chat -v -f /etc/ppp/chat-isp' + +If there are any other pppd options that should apply when calling +this ISP, they can also be placed in this file. + +The /etc/ppp/chat-isp file named in the last line contains the script +for chat(8) to use to dial the ISP and go through any username/ +password authentication required before PPP service starts. Here is +an example (for dialling an Annex terminal server): + +ABORT "NO CARRIER" +ABORT "NO DIALTONE" +ABORT "ERROR" +ABORT "NO ANSWER" +ABORT "BUSY" +ABORT "Username/Password Incorrect" +"" "at" +OK "at&d2&c1" +OK "atdt2479381" +"name:" "^Uusername" +"word:" "\qpassword" +"annex" "ppp" +"Switching to PPP-ppp-Switching to PPP" + +See the chat(8) man page for details of the script. If you are not +sure how the initial dialog with your ISP will go, you could use +a terminal emulator such as kermit or minicom to go through the +process manually. + +If your ISP requires PAP or CHAP authentication, you will have to +create a line in /etc/ppp/pap-secrets or /etc/ppp/chap-secrets like +this: + +myhostname * "password" + +(Replace myhostname with the hostname of your machine.) + +At this point, you can initiate the link with the command: + +/usr/sbin/pppd call isp + +(N.B.: pppd might be installed in a different directory on some +systems). + +This will return to the shell prompt immediately, as pppd will detach +itself from its controlling terminal. (If you don't want it to do +this, use the "nodetach" option.) + +Pppd will log messages describing the progress of the connection and +any errors using the syslog facility (see the syslogd(8) and +syslog.conf(5) man pages). Pppd issues messages using syslog facility +daemon (or local2 if it has been compiled with debugging enabled); +chat uses facility local2. It is often useful to see messages of +priority notice or higher on the console. To see these, find the line +in /etc/syslog.conf which has /dev/console on the right-hand side, and +add `daemon.notice' on the left. This line should end up something +like this: + +*.err;kern.debug;daemon,local2,auth.notice;mail.crit /dev/console + +If you want to see more messages from pppd, request messages of +priority info or higher for facility daemon, like this: + +*.err;kern.debug;daemon.info;local2,auth.notice;mail.crit /dev/console + +It is also useful to add a line like this: + +daemon,local2.debug /etc/ppp/ppp-log + +If you do this, you will need to create an empty /etc/ppp/ppp-log +file. + +After modifying syslog.conf, you will then need to send a HUP signal +to syslogd (or reboot). + +When you wish terminate the PPP link, you should send a TERM or INTR +signal to pppd. Pppd writes its process ID to a file called +ppp.pid in /var/run (or /etc/ppp on older systems such as SunOS or +Ultrix). Here is the PPP interface unit number, which will be 0 +unless you have more than one PPP link running simultaneously. Thus +you can terminate the link with a command like + + kill `cat /var/run/ppp0.pid` -- cgit v1.2.1
