BSD Dial Setup
This document assumes that you are using an external modem connected to a serial port. Do not use an internal or “Winmodem” because these units aren’t real modems. They use software running on the host computer to emulate a modem and that software usually only runs under Windows. There are a few exceptions.
This document further assumes that you are running a default kernel or a custom kernel with PPP compiled in. Without PPP, you won’t be able to make a dial-up connection to the Internet.
For a thorough introduction to running ppp on FreeBSD, see FreeBSD Handbook. On most FreeBSD installs, copies of this document can be found in your “/usr/share/doc” directory.
As root, edit these configuration files:
Edit /etc/resolv.conf to look like this:
domain eskimo.com nameserver 18.104.22.168 nameserver 22.214.171.124
Edit /etc/group and add the users who will be allowed to initiate a PPP dial-up session to the network group.
Edit /etc/ppp/ppp.conf. In the demand style configuration template which follows:
- PPPLOGIN is your PPP account login name
- PPPPASSWD is your PPP account password
- DIALNUMBER is your local access number
- timeout is set to 400 secs of idle
- only alice, bob are permitted to use ppp
- /dev/cuaa1 is the modem port
If PPPLOGIN contains a punctuation like an ‘@’ sign, it must be escaped with a backslash “\” (example: “foo\@eskimo.com”).
default: allow users alice bob carol set device /dev/cuaa1 set log Phase Chat LCP IPCP CCP tun command set speed 115200 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 15 \"\" \ AT&F&C1&D2 OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT" set redial 3 10 demand: set phone DIALNUMBER set login "TIMEOUT 10 ogin:--ogin: PPPLOGIN word: PPPPASSWD" set timeout 400 set openmode active set ifaddr 10.1.1.127/0 10.2.2.127/0 255.255.255.0 0.0.0.0 add 0 0 10.2.2.127
Edit /etc/ppp/ppp.linkup to look like this:
demand: # configuration must delete routes first delete ALL add 0 0 HISADDR MYADDR: # for non-demand configurations add 0 0 HISADDR
Should you encounter any difficulties, logs are usually kept in /var/log/messages.
That’s it! You are all set up now. If you are in the network group, you can connect by executing:
/usr/sbin/ppp -auto demand
To start the ppp daemon automatically when the system boots, add a line like this to your /etc/rc.local file:
su -m ripper -c "ppp -auto -quiet demand"
(Note: in -auto mode, dialing commences with your first net access.)
