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.

The following is one way to set up a FreeBSD machine for SLIP on a
|
|
static host network. For dynamic hostname assignments (i.e., your
|
|
address changes each time you dial up), you probably need to do
|
|
something much fancier.
|
|

This is just "what I did, and it worked for me". I am sharing this
|
|
just for your reference, I am no expert in SLIP nor networking so your
|
|
mileage may vary.

First, determine which serial port your modem is connected to. I have
|
|
a symbolic link <tt>/dev/modem -> cuaa1</tt>, and only use the modem name in my
|
|
configuration files. It can become quite cumbersome when you need to
|
|
fix a bunch of files in <tt>/etc</tt> and <tt>.kermrc</tt>'s all over the system! (Note
|
|
that <tt>/dev/cuaa0</tt> is COM1, <tt>cuaa1</tt> is COM2, etc.)
|
|
|
|
Make sure you have
|
|
<verb>
|
|
pseudo-device sl 1
|
|
</verb>
|
|
in your kernel's config file. It is included in the GENERIC kernel,
|
|
so this will not be a problem unless you deleted it.
|

<sect1><heading>Things you have to do only once</heading>
|
|
|
|
<p><enum>
|
|
<item>Add your home machine, the gateway and nameservers to your
|
|
<tt>/etc/hosts</tt> file. Mine looks like this:
|
|
<verb>
|
|
127.0.0.1 localhost loghost
|
|
136.152.64.181 silvia.HIP.Berkeley.EDU silvia.HIP silvia
|
|

128.32.136.9 ns1.Berkeley.edu ns1
|
|
128.32.136.12 ns2.Berkeley.edu ns2
|
|
</verb>
|
|
By the way, silvia is the name of the car that I had when I was
|
|
back in Japan (it is called 2?0SX here in U.S.).
|
|
|
|
<item>Make sure you have "hosts" before "bind" in your <tt>/etc/host.conf</tt>.
|
|
Otherwise, funny things may happen.
|
|
|
|
<item>Edit the file <tt>/etc/sysconfig</tt>.
|
|
<enum>
|
|
<item>Set your hostname by editing the line that says:
|
|
<verb>
|
|
hostname=myname.my.domain
|
|
</verb>
|
|
You should give it your full Internet hostname.
|
|
|
|
<item>Add sl0 to the list of network interfaces by changing the line
|
|
that says:
|
|
<verb>
|
|
network_interfaces="lo0"
|
|
</verb>
|
|
to:
|
|
<verb>
|
|
network_interfaces="lo0 sl0"
|
|
</verb>
|
|
|
|
<item>Set the startup flags of sl0 by adding a line:
|
|
<verb>
|
|
ifconfig_sl0="inet ${hostname} slip-gateway netmask 0xffffff00 up"
|
|
</verb>
|
|
|
|
<item>Designate the default router by changing the line:
|
|
<verb>
|
|
defaultrouter=NO
|
|
</verb>
|
|
to:
|
|
<verb>
|
|
defaultrouter=slip-gateway
|
|
</verb>
|
|
</enum>
|
|
|
|
<item>Make a file <tt>/etc/resolv.conf</tt> which contains:
|
|
<verb>
|
|
domain HIP.Berkeley.EDU
|
|
nameserver 128.32.136.9
|
|
nameserver 128.32.136.12
|
|
</verb>
|
|
As you can see, these set up the nameserver hosts. Of course, the
|
|
actual domain names and addresses depend on your environment.
|
|
|
|
<item>Set the password for root and toor (and any other accounts that
|
|
does not have a password). Use passwd, do not edit the <tt>/etc/passwd</tt>
|
|
or <tt>/etc/master.passwd</tt> files!
|
|
|
|
<item>Reboot your machine and make sure it comes up with the correct
|
|
hostname.

<sect1><heading>Making a SLIP connection</heading>
|
|
|
|
<p><enum>
|
|
<item>Dial up, type "slip" at the prompt, enter your machine name and
|
|
password. The things you need to enter depends on your
|
|
environment. I use kermit, with a script like this:
|
|
<verb>
|
|
# kermit setup
|
|
set modem hayes
|
|
set line /dev/modem
|
|
set speed 115200
|
|
set parity none
|
|
set flow rts/cts
|
|
set terminal bytesize 8
|
|
set file type binary
|
|
# The next macro will dial up and login
|
|
define slip dial 643-9600, input 10 =>, if failure stop, -
|
|
output slip\x0d, input 10 Username:, if failure stop, -
|
|
output silvia\x0d, input 10 Password:, if failure stop, -
|
|
output ***\x0d, echo \x0aCONNECTED\x0a
|
|
</verb>
|
|
(of course, you have to change the hostname and password to fit
|
|
yours). Then you can just type "slip" from the kermit prompt to
|
|
get connected.
|
|
|
|
<bf>Note</bf>: leaving your password in plain text anywhere in the
|
|
filesystem is generally a BAD idea. Do it at your own risk. I am
|
|
just too lazy.
|
|
|
|
<item>Leave the kermit there (you can suspend it by "z") and as root,
|
|
type
|
|
<verb>
|
|
slattach -h -c -s 115200 /dev/modem
|
|
</verb>
|
|
if you are able to "ping" hosts on the other side of the router,
|
|
you are connected! If it does not work, you might want to try "-a"
|
|
instead of "-c" as an argument to slattach.
|
|
</enum>
|
|
|
|
<sect1><heading>How to shutdown the connection</heading>
|
|
|
|
<p>Type "kill -INT `cat /var/run/slattach.modem.pid`" (as root) to
|
|
kill slattach. Then go back to kermit ("fg" if you suspended it)
|
|
and exit from it ("q").
|
|
|
|
The slattach man page says you have to use "ifconfig sl0 down" to
|
|
mark the interface down, but this does not seem to make any
|
|
difference for me. ("ifconfig sl0" reports the same thing.)
|
|
|
|
Some times, your modem might refuse to drop the carrier (mine
|
|
often does). In that case, simply start kermit and quit it again.
|
|
It usually goes out on the second try.

<sect1><heading>Troubleshooting</heading>
|
|
|
|
<p>If it does not work, feel free to ask me. The things that people
|
|
tripped over so far:
|
|
<itemize>
|
|
<item>Not using "-c" or "-a" in slattach (I have no idea why this can be
|
|
fatal, but adding this flag solved the problem for at least one
|
|
person)
|
|
|
|
<item>Using "s10" instead of "sl0" (might be hard to see the difference on
|
|
some fonts.
|
|
|
|
<item>Try "ifconfig sl0" to see your interface status. I get:
|
|
<verb>
|
|
silvia# ifconfig sl0
|
|
sl0: flags=10<POINTOPOINT>
|
|
inet 136.152.64.181 --> 136.152.64.1 netmask ffffff00
|
|
</verb>
|
|
|
|
<item>Also, <tt>netstat -r</tt> will give the routing table, in case you get
|
|
the "no route to host" messages from ping. Mine looks like:
|
|
<verb>
|
|
silvia# netstat -r
