Hi Jhun,

Yes, Red Hat supports ppp very well, similar to that offered by Windows RAS,
but with many more granular options.

1) install mgetty and ppp from your linux distribition

2) add the following entries in /etc/inittab (this assumes two modems - on
ttyS0 (com1) and ttyS1 (com2)

        d1:345:respawn:/sbin/mgetty ttyS0 > /dev/nul
        d2:345:respawn:/sbin/mgetty ttyS1 > /dev/nul

this will respawn mgetty if it dies.

3) edit /etc/mgetty+sendfax/login.config -- this should be the only line
concerning AutoPPP (remember it is case sensitive -- AutoPPP)
        /AutoPPP/ - dialin /usr/sbin/pppd file /etc/ppp/dialin-options

this line tells mgetty to execute the ppp daemon with options cotained in
/etc/ppp/dialin-options

4) create /etc/ppp/dialin-options
        +chap
        asyncmap 0
        10.1.1.254:10.1.1.1
        ipcp-accept-remote
        #ipcp-accept-local
        ipparam dialin
        linkname dialin
        #kdebug 7
        #debug
        logfile /var/log/ppp.dialin
        ms-dns 172.16.3.9
        ms-wins 172.16.3.9

these are my options, some are remarked out, and you'll need to decide which
ones you want and change ip addresses accordingly. check out the man page
for pppd, it has all the options listed with their various meanings.

5) edit /etc/modules.conf and add the lines
        alias /dev/ppp ppp_generic
        alias char-major-108 ppp_generic
        alias tty-ldisc-3 ppp_async
        alias tty-ldisc-14 ppp_synctty
        alias ppp-compress-21 bsd_comp
        alias ppp-compress-24 ppp_deflate
        alias ppp-compress-26 ppp_deflate

this should get the compression scheme right with the kernel screaming.

6) edit /etc/ppp/chap-secrets to include the usernames and passwords of
dialin users. note that chap is more secure than pap -- my configuration
includes only support for chap (the chap+) in dialin options.


Reboot and give it a try.

Voila!

Subject: setting dial-in server


Hi,

I'm planning of putting up a dial-in server in our office. My purpose for
this is for me to be able to dial-up to that server and be
connected to our server. Just like RAS. Anybody here that guide me on how
to set it up? I was planning of using Redhat 8.0.

TIA

Jhun Bacala
