Configuring FreeBSD for dial-in service *This article talks about how you can configure FreeBSD to accept incoming connections over a modem (i.e. a dial-in service). This will be done via PPP.
See also http://www.ssimicro.com/~jeremyc/ppp.html which I’m told is quite good.
Where to startThe first place I started was with the FreeBSD Handbook. I went straight to the PPP and Slip section. You should scroll down until you see Receiving incoming calls with ppp. I also used Dialin Service.
I installed 3.2-RELEASE and mgetty+sendfax on both machines.
Where I stoppedWell, that was about it. I didn’t continue. Then NutBoy on Undernet sent me the following. I have not tried this. Comments on this article will be appreciated.
NutBoy’s article (firstname.lastname@example.org)I decided I’d try to set up my dual 450 box for dialin service, so when I was away or at work I could dial in on my second line and connect to the Internet. I had many many problems and this will show you what exactly to check.
I started out with the dial-in section in the FreeBSD Handbook which ended up being semi-useless and outdated as I am running a 3.2-stable machine.
What I ended up doing was:
in /etc/rc.conf:enable proxy gateway=enable
I used getty, not mgetty.
Add a new user whom you want to let use ppp. In this test circumstance, I used the user "ppp" with home being /home/ppp and shell being /etc/ppp/ppp-shell.
#!/bin/sh IDENT=`echo $0 | sed -e 's/^.*-\(.*\)$/\1/'` CALLEDAS="$IDENT" TTY=`tty` if [ x$IDENT = xdialup ]; then IDENT=`basename $TTY` fi echo "PPP for $CALLEDAS on $TTY" echo "Starting PPP for $IDENT" exec /usr/sbin/ppp -direct $IDENT
I then made 2 files in the ppp home directory:
-r--r--r-- 1 root wheel 0 Jul 26 05:43 .hushlogin -r--r--r-- 1 root wheel 0 Jul 26 05:45 .rhosts
I then added a /etc/ppp/ppp.conf script:
ttyd0: enable pap enable passwdauth set ifaddr 22.214.171.124 126.96.36.199 255.255.255.255 enable proxy
This set the dialin with the IP 188.8.131.52.
I then added a /etc/ppp/ppp.linkup addition:
ttyd0: add 184.108.40.206 netmask 255.255.255.255 HISADDR
I then made a ppp.secret addition (for use with PAP). If you aren’t using PAP you will not need this:
# Authname Authkey Peer's IP address ppp password 220.127.116.11
After that I checked /etc/ttys and /etc/gettytab and enabled ttyd0 and made sure that a reasonable speed setting was there and placed.
After all this I was ready to try…..Nothing….the box wouldn’t answer the phone.
Two days later:I realized that my modem isn’t ansering and there is no setup utility to change the nvram. There are also no jumpers to make it autoanswer. Off to the store. I picked up a new modem that has config jumpers. I changed it to serial port 1 and to autoanswer. Booted up….
Perfect, answers the connection and everything is fine.
