The following is an exerpt from the #7 FAQ(communictions), with
many questions from me added in. These questions are both specific
to SLIP and general UNIX questions. I hope that i Don't offend anyone
by posting this but i'm confused about how to set up a SLIP server on
my FreeBSD1.1.5.1 machine and the FAQ's that i have read only bring
up more questions. So if you would rather not wast your time helping
No, no offense taken. I was just reading our own slip faq the other
day myself (I already KNOW how to use SLIP so I am sometimes remiss in
going back to read some of our own independantly provided user doc!)
and thinking "Hmmm. This needs some work!" In fact, it'd appear that
the doc you read is even more in need of work than ours given that
it's rather out of date. For future reference, FreeBSD specific
questions are really generally better handled by our own FAQ, which
you can find in:
freebsd.cdrom.com:~ftp/pub/FreeBSD/FAQ
Not to malign Dave Burgess's FAQ, but he has a much harder time
keeping all the information up-to-date considering its sheer size.
Anyway, let me see if I can answer some of your questions.
If you have suggestions for good UNIX books this is welcomed also.
ANY help is appreciated!
Evi Nemeth's system administration book is supposed to be good. The
Berkeley UNIX docs help a fair bit too. But moving right along..
I don't have any com0 or com1 in the /dev directory. Should it be there?
Can they be added? Can a tty** device be used instead. Also is there differances
It's /dev/tty<nn> now. The /dev/com* names are longer used (and haven't been
for awhile). /dev/tty00 == COM1, /dev/tty01 == COM2, etc.

Are tip and cu used by SLIP, or is this just to verify that the devices are working
tip and cu are just methods of connecting to the serial port and
interacting with it. I use kermit for this purpose, myself.

> chown uucp.dialer /var/log/aculog
Why do the devices have to be owened by uucp and in the group dialer?
Well, the log should so that uucp can write to it too. This example
assumes that you're going to be sharing your line for both uucp and SLIP,
which is probably not your case anyway.

> 11.22.33.55 client.my.domain.name client
Do i really need to tell the server its own IP number in the hosts file?
Yes, if you want to be able to refer to it by name in your own login
scripts and such. You're not "telling the server its own name", you're
telling YOU the server's name! :-)
I'm under the impression that kermit is a file transfer protocol, so this
make's no sence to me. Can you use just a Comm progrm like Procomm?
kermit is both a file transfer protocol and a program that's handy for
connecting to things, like procomm. You could use procomm, but I
rather doubt if procomm could later be made to work as a `hands off'
dialer script, the way kermit can. When I want to connect to the
network I simply type `slup' (short for slip up) and this invokes
kermit on a script that dials the phone, logs me in, selects SLIP or
optional PPP service, and then goes on to invoke slattach for the
line. All automatic, I don't type anything else. Likewise, I have another
script `sldown' that kills the slattach and then invokes kermit to go
hang up the line.
Is the effect of the Slattach, ifconfig and route add saved somewhere? Or
do i need to add this to a login type file so it runs everytime a user logs in?
You run slattach every time you want to invoke the connection. This much
is covered fairly well in our own FAQ, so I'll just let you go and read
that at this point! :)
