Configuring a Machine on the Leased Line

The task in this section explains how to set up a router to function as the local peer on your end of a leased line. The task uses the leased line that was introduced in Example of a Configuration for a Leased-Line Link as an example.

Prerequisites for Configuring the Local Machine on a Leased Line

Before you perform the next procedure, you must have completed the following:

How to Configure a Machine on a Leased Line

  1. Become an administrator on the local machine (router).

    For more information, see How to Use Your Assigned Administrative Rights in Oracle Solaris 11.1 Administration: Security Services.

  2. Add an entry for the remote peer in the router's /etc/hosts file.
    # cat /etc/hosts
    #
    # Internet host table
    #
    127.0.0.1       localhost
    192.168.130.10  local2-peer        loghost
    192.168.130.11  local1-net
    10.0.0.25       farISP

    The example /etc/hosts file is for the local router at the fictitious LocalCorp. Note the IP address and host name for the remote peer farISP at the service provider.

  3. Create the file /etc/ppp/peers/peer-name to hold information about the provider's peer.

    For this example leased-line link, you create the file /etc/ppp/peers/farISP.

    # cat /etc/ppp/peers/farISP
    init '/etc/ppp/conf_hsi'
    local
    /dev/hihp1
    sync
    noauth
    192.168.130.10:10.0.0.25
    passive
    persist
    noccp
    nopcomp
    novj
    noaccomp

    The following table explains the options and parameters that are used in /etc/ppp/peers/farISP.


    Option
    Definition
    init '/etc/ppp/conf_hsi'
    Starts the link. init then configures the HSI interface by using the parameters in the script /etc/ppp/conf_hsi.
    local
    Tells the pppd daemon not to change the state of the Data Terminal Ready (DTR) signal. Also tells pppd to ignore the Data Carrier Detect (DCD) input signal.
    /dev/hihp1
    Gives the device name of synchronous interface.
    sync
    Establishes synchronous encoding for the link.
    noauth
    Establishes that the local system does not need to demand authentication from the peer. However, the peer could still demand authentication.
    192.168.130.10:10.0.0.25
    Defines the IP addresses of the local peer and the remote peer, separated by a colon.
    passive
    Tells the pppd daemon on the local machine to go quiet after issuing maximum number of LCP Configure-Requests and to wait for the peer to start.
    persist
    Tells the pppd daemon to try to restart the link after a connection ends.
    noccp, nopcomp, novj, noaccomp
    Disables the Compression Control Protocol (CCP), Protocol Field compression, Van Jacobson compression, and address and control field compression, respectively. These forms of compression accelerate transmissions on a dial-up link but could slow down a leased line.
  4. Create an initialization script that is called demand, which creates the PPP link as part of the booting process.
    # cat /etc/ppp/demand
    #!/bin/sh
    if [ -f /system/volatile/ppp-demand.pid ] &&
       /usr/bin/kill -s 0 `/bin/cat /system/volatile/ppp-demand.pid`
    then
            :
    else
            /usr/bin/pppd call farISP
    fi

    The demand script contains the pppd command for establishing a leased-line link. The following table explains the content of $PPPDIR/demand.


    Code Sample
    Explanation
    if [ -f /system/volatile/ppp-demand.pid ] && /usr/bin/kill -s 0 `/bin/cat /system/volatile/ppp-demand.pid`
    These lines check to see if pppd is running. If pppd is running, it does not need to be started.
    /usr/bin/pppd call farISP
    This line launches pppd. pppd reads the options from /etc/ppp/options. The call farISP option on the command line causes it to read /etc/ppp/peers/farISP, also.

    The Solaris PPP 4.0 startup script /etc/rc2.d/S47pppd invokes the demand script as part of the booting process. The following lines in /etc/rc2.dS47pppd search for the presence of a file that is called $PPPDIR/demand.

        if [ -f $PPPDIR/demand ]; then
                    . $PPPDIR/demand
            fi
            

    If found, $PPPDIR/demand is executed. During the course of executing $PPPDIR/demand, the link is established.


    Note - To reach machines outside the local network, have users run telnet, ftp, rsh, or similar commands.
