mpp 379ee1865d (This really shouldn't all be on one commit, but I forgot
I was in the middle of one of these "projects" when I started
on the next, so they wound up all intermixed)

Move the mailing list entities from authors.sgml to the new file
lists.sgml.  Add an entity for majordomo at the same time.

Avoid the use of contractions.  This revealed some grammer problems,
and also has the benefit of helping make things clearer for those people
who do make speak English as a their first language.

<sect><heading>Setting up kernel PPP<label id="ppp"></heading>
<p><em>Contributed by &a.gena;.</em>
Before you start setting up PPP on your machine make
sure that pppd is located in /usr/sbin and directory /etc/ppp
exists.
pppd can work in two modes:
<enum>
<item> as a "client" , i.e. you want to connect your machine to outside
world via PPP serial connection or modem line.
<item> as a "server" , i.e. your machine is located on the network and
used to connect other computers using PPP.
</enum>
In both cases you will need to set up an options file (<tt>/etc/ppp/options</tt>
or <tt>~/.ppprc</tt> if you have more then one user on your machine that uses
PPP).
You also will need some modem/serial software ( preferably kermit )
so you can dial and establish connection with remote host.
<sect1><heading>Working as a PPP client</heading>
<p>I used the following <tt>/etc/ppp/options</tt> to connect to CISCO terminal
server PPP line.
<verb>
crtscts # enable hardware flow control
modem # modem control line
noipdefault # remote PPP server must supply your IP address.
# if the remote host doesn't send your IP during IPCP
# negotiation , remove this option
passive # wait for LCP packets
domain ppp.foo.com # put your domain name here
:<remote_ip> # put the IP of remote PPP host here
# it will be used to route packets via PPP link
# if you didn't specified the noipdefault option
# change this line to <local_ip>:<remote_ip>
defaultroute # put this if you want that PPP server will be your
# default router
</verb>
To connect:
<enum>
<item> Dial to the remote host using kermit ( or other modem program )
enter your user name and password ( or whatever is needed to enable PPP
on the remote host )
<item> Exit kermit. ( without hanging up the line )
<item> enter:
<verb>
/usr/src/usr.sbin/pppd.new/pppd /dev/tty01 19200
</verb>
( put the appropriate speed and device name )
</enum>
Now your computer is connected with PPP. If the connection fails for some
reasons you can add the "debug" option to the <tt>/etc/ppp/options</tt> file
and check messages on the console to track the problem
Following <tt>/etc/ppp/pppup</tt> script will make all 3 stages automatically:
<verb>
#!/bin/sh
ps ax |grep pppd |grep -v grep
pid=`ps ax |grep pppd |grep -v grep|awk '{print $1;}'`
if [ "X${pid}" != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill ${pid}
fi
ps ax |grep kermit |grep -v grep
pid=`ps ax |grep kermit |grep -v grep|awk '{print $1;}'`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
ifconfig ppp0 down
ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.dial
pppd /dev/tty01 19200
</verb>
<tt>/etc/ppp/kermit.dial</tt> is kermit script that dials and makes all
necessary authorization on the remote host.
( Example of such script is attached to the end of this document )
Use the following <tt>/etc/ppp/pppdown</tt> script to disconnect the PPP line:
<verb>
#!/bin/sh
pid=`ps ax |grep pppd |grep -v grep|awk '{print $1;}'`
if [ X${pid} != "X" ] ; then
echo 'killing pppd, PID=' ${pid}
kill -TERM ${pid}
fi
ps ax |grep kermit |grep -v grep
pid=`ps ax |grep kermit |grep -v grep|awk '{print $1;}'`
if [ "X${pid}" != "X" ] ; then
echo 'killing kermit, PID=' ${pid}
kill -9 ${pid}
fi
/sbin/ifconfig ppp0 down
/sbin/ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.hup
/etc/ppp/ppptest
</verb>
Check if PPP is still running (<tt>/usr/etc/ppp/ppptest</tt>):
<verb>
#!/bin/sh
pid=`ps ax| grep pppd |grep -v grep|awk '{print $1;}'`
if [ X${pid} != "X" ] ; then
echo 'pppd running: PID=' ${pid-NONE}
else
echo 'No pppd running.'
fi
set -x
netstat -n -I ppp0
ifconfig ppp0
</verb>
Hangs up modem line (<tt>/etc/ppp/kermit.hup</tt>):
<verb>

Use this <tt>/etc/ppp/pppservdown</tt> script to stop ppp server:
<verb>
#!/bin/sh

ifconfig ppp0 down
ifconfig ppp0 delete
kermit -y /etc/ppp/kermit.noans

Following kermit script will enable/disable autoanswer mode

<verb>

This <tt>/etc/ppp/kermit.dial</tt> script is used for dialing and authorizing
on remote host. You will need to customize it for your needs.
Put your login and password in this script , also you will need
to change input statement depending on responses from your modem
and remote host.
