This is how I configured PPP in linux to run with SLiRP on hopi.  It
may not be the best way to configure it, but it works.  If you can tell
me how to make it faster, etc, please do.  I read that SLiRP tends to be
faster than real PPP because the host does the buffering, but that
didn't seem to be the case for me.  Then again, it also said that it
depends on your situation.  I bet you could script it, but minicom
works, so that's what I'm using.  

1.  edit /etc/resolv.conf so that it looks like this:


#########################

domain dtcc.edu
search dtcc.edu
nameserver 138.123.84.240
nameserver 10.0.2.3

#########################


2. edit /etc/ppp/options so that it looks like this:

####################################################

/dev/cua2  # this should be the com port your modem is on
           # mine happens to be cua2, set it to yours
           # cua0 = com1, cua1 = com2, cua2 = com3, etc.

#/dev/ttyS2
detach
lock
mru 1500
mtu 1500
#kdebug 15
debug
crtscts 
modem 
10.0.2.15:138.123.84.1
defaultroute 
netmask 255.255.255.0
#noipdefault
asyncmap 0

###################################################


   Ok, now pppd should be set up correctly, but if you haven't done
so already, YOU MUST read the information regarding slirp at
http://www.dtcc.edu/cs/slirp !!!  This is just the configuration for PPP
locally.  

   I dial up with minicom, get the terminal into binary mode and run
slirp according to the information at www.dtcc.edu/cs/slirp

Then I quit without resetting the modem (rather important). After
that you can run pppd (man pppd for details, it's the ppp software for
linux).  

You need to set up .slirprc in your directory on hopi.  Also
remember that this is PPP, not SLIP, so you'll need to use the -P
switch, eg.

exec slirp -P




   Okay that's about it.  My email address is w524@hopi.dtcc.edu if you
have any comments or questions.  Have Fun people.
