pppd problem

I am a beginner in Linux.  I just setup Slackware 3.4 on my office
PC-486 (AMD66, w/ 32M RAM, 2G IDE HD + 124M IDE HD).  This PC is
connected to Internet through the campus network (ethernet).  Everything
works very well, I can telnet/ftp to this PC, send and receive email,
etc.  As the campus network has a dial-up server (for students to dial
on and then telnet to telnet host on campus, so I setup my home PC
(Pentium 133, 32M ram, 2.1G IDE HD, 28.8K Modem, running WIN 95) as a
PPP client with a static IP address.  I dialed up to the campus dial-up
server and telnet to my Linux machine as root.   Then I started PPP
daemon by pppd and it worked!  But when I tried applications in Win 95
such as netscape and ftp, they were very slow! (for ftp, about 1K/sec).
I believe that the Modem speed on the campus dial-up server should no
slower than 28.8K, so what seems to be the problem?

BTW, before I using pppd, I didn't setup anything about it, so, should I
config something on pppd?

My 2nd question is, how to get the total used and free diskspace on
Linux system?

And here is the 3rd question: I want to redirect a man page to a file
and get rid of the text formatting information in it, is there any pipe
function I can use to do this?

Thanks in advance!

try making a user name ppp with a shell called /etc/ppp/ppplogin

pppd script should be executed when you login as ppp to the ppp server which is the linux box in return executes the inserts of /etc/ppp/ppplogin

here's the site for the ppplogin script

you should use mgetty+sendfax as your ppp server
here's the url for the mgetty+sendfax, this stuff is very simple.

note: remmeber you should issue this command to the pppd program

chmod 700 pppd
chown root.root pppd

Thank you jefx for your help, I just find the ppplogin script, but the second link you gave can not be found!

Also, what do you mean by "using ... as the ppp server" ?
My Linuxbox doesn't have a modem, instead, I telnet to it from a dial-up server.  In this case, do I still need mgetty?

Thanks again for your help
