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
|
|

|

kill -TERM ${pid}
|

|

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}
