*** How to Set Up SLIP on FreeBSD ***
|
|
***********************************************************************
|
|
|
|
Updated for 1.1.5(.1) support by Satoshi Asami, 8/6/94.
|
|
|
|
The following is I (asami) set up my 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'm sharing this
|
|
just for your reference, I'm no expert in SLIP nor networking so your
|
|
mileage may vary.
|
|
|
|
Note: for 1.1 systems (not 1.1.5), you need to use /dev/tty01 instead
|
|
of /dev/cua01. substitute all the occurences of "cua" in this document
|
|
with "tty".
|
|
|
|
Note: the default 1.1.5(.1) system only comes with cua/ttyd pairs for
|
|
the last two ports (2 and 3), so if your modem is at sio0/sio1
|
|
(COM1/COM2), you need to make the devices. Try "cd /dev; sh MAKEDEV
|
|
cua01" to make the new special files for sio1 (ditto for sio0). This
|
|
will delete tty01, but you shouldn't need it anymore...or you can make
|
|
a symbolic link /dev/tty01 -> ttyd1 if you don't want to hunt down all
|
|
occurences of tty01 in your setup files.
|
|
|
|
I actually have a symbolic link /dev/modem -> cua01 (and /dev/mouse ->
|
|
ttyd0). I use only the modem/mouse names in my configuration files.
|
|
This helped a lot when I switched from 1.1 to 1.1.5.1 (tty01 => cua01)
|
|
and when I had to move my modem temporarily to sio2 to enable the
|
|
RS-232C port on the serial card. It can become quite cumbersome when
|
|
you need to fix a bunch of files in /etc and .kermrc's all over the
|
|
system!
|
|
|
|
First, make sure you have
|
|
|
|
pseudo-device sl 2
|
|
|
|
in your kernel's config file. It is included in the GENERICAH and
|
|
GENERICBT kernels, so this won't be a problem unless you deleted it.
|
|
|
|
Things you have to do only once:
|
|
|
|
(1) Add your home machine, the gateway and nameservers to your
|
|
/etc/hosts file. Mine looks like this:
|
|
|
|
127.0.0.1 localhost loghost
|
|
136.152.64.181 silvia.HIP.Berkeley.EDU silvia.HIP silvia
|
|
|
|
136.152.64.1 inr-3.Berkeley.EDU inr-3 slip-gateway
|
|
128.32.136.9 ns1.Berkeley.edu ns1
|
|
128.32.136.12 ns2.Berkeley.edu ns2
|
|
|
|
By the way, silvia is the name of the car that I had when I was
|
|
back in Japan (it's called 2?0SX here in U.S.).
|
|
|
|
(2) Make sure you have "hosts" before "bind" in your /etc/host.conf.
|
|
Otherwise, funny things may happen.
|
|
|
|
(3) Edit the /etc/netstart and add this to the end of the file:
|
|
|
|
# set up slip
|
|
gateway=slip-gateway
|
|
ifconfig sl0 inet $hostname $gateway netmask 0xffffff00
|
|
route add default $gateway
|
|
|
|
Note that because of the "slip-gateway" entry in /etc/hosts, there
|
|
is no local dependency in the netstart file. Also, you might want
|
|
to un-comment the "route add $hostname localhost" line.
|
|
|
|
(3') Make a file /etc/resolv.conf which contains:
|
|
|
|
domain HIP.Berkeley.EDU
|
|
nameserver 128.32.136.9
|
|
nameserver 128.32.136.12
|
|
|
|
As you can see, these set up the nameserver hosts. Of course, the
|
|
actual addresses depend on your environment.
|
|
|
|
(4) Set the password for root and toor (and any other accounts that
|
|
doesn't have a password). Use passwd, don't edit the passwd or
|
|
passwd.master files!
|
|
|
|
(5) Edit /etc/myname and reboot the machine.
|
|
|
|
How to set up the connection:
|
|
|
|
(6) 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:
|
|
|
|
# kermit setup
|
|
set modem hayes
|
|
set line /dev/cua01
|
|
set speed 57600
|
|
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
|
|
|
|
(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.
|
|
|
|
Note: leaving your password in plain text anywhere in the
|
|
filesystem is generally a BAD idea. Do it at your own risk. I'm
|
|
just too lazy.
|
|
|
|
Note: If you have an 1.1 machine, and kermit doesn't give you a
|
|
prompt, try "stty -f /dev/tty01 clocal". I put this in
|
|
/etc/rc.local so that it works the first time I boot the machine.
|
|
This doesn't apply to 1.1.5(.1) systems, as cua0? are already
|
|
configured for dialouts.
|
|
|
|
(7) Leave the kermit there (you can suspend it by "z") and as root,
|
|
type
|
|
|
|
slattach -h -c -s 57600 /dev/cua01
|
|
|
|
if you are able to "ping" hosts on campus, you are connected!
|
|
|
|
If it doesn't work, you might want to try "-a" instead of "-c".
|
|
|
|
(8) Happy slipping!
|
|
|
|
How to shutdown the connection:
|
|
|
|
(9) Type "ps gx" (as root) to find out the PID of slattach, and use
|
|
"kill -INT" to kill it.
|
|
|
|
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 doesn't 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.
|
|
|
|
When you want to connect again, go back to (6). You may have to
|
|
watch out for clocal mode. If "stty -f /dev/tty01" doesn't tell
|
|
you it's clocal, you need to re-set it before kermitting. Again,
|
|
this is only for 1.1 machines.
|
|
|
|
TROUBLESHOOTING:
|
|
|
|
If it doesn't work, feel free to ask me. The things that people
|
|
tripped over so far:
|
|
|
|
* 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)
|
|
|
|
* Using "s10" instead of "sl0" (might be hard to see the difference on
|
|
some fonts :)
|
|
|
|
Try "ifconfig sl0" to see your interface status. I get:
|
|
|
|
silvia# ifconfig sl0
|
|
sl0: flags=10<POINTOPOINT>
|
|
inet 136.152.64.181 --> 136.152.64.1 netmask ffffff00
|
|
|
|
Also, "netstat -r" will give the routing table, in case you get the
|
|
"no route to host" messages from ping. Mine looks like:
|
|
|
|
silvia# netstat -r
|
|
