I found that using user ppp rather than pppd was easier to set
up. Maybe that's because I was more familiar with it.
Anyway, with user ppp there is no need to use ifconfig -- all the
interface setup is done in the ppp.conf file.
I don't know how to setup IPv6 and so never tried to make the link
anything but IPv4.
Here is what my /etc/ppp/ppp.conf file looked like from one machine:
default:
ident user-ppp VERSION (built COMPILATIONDATE)
# Ensure that "device" references the correct serial port
# for your modem. (cuaa0 = COM1, cuaa1 = COM2)
#
set device /dev/cuaa0
set log Phase Chat LCP IPCP CCP tun command
set speed 115200
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
\"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
set timeout 180 # 3 minute idle timer (the default)
# add default HISADDR # Add a (sticky) default route
# enable dns # request DNS info (for resolv.conf)
papchap:
#
# edit the next three lines and replace the items in caps with
# the values which have been assigned by your ISP.
#
set phone PHONE_NUM
set authname USERNAME
set authkey PASSWORD
other-host-name:
ident user-ppp VERSION (built COMPILATIONDATE)
# Ensure that "device" references the correct serial port
# for your modem. (cuaa0 = COM1, cuaa1 = COM2)
#
set device /dev/cuaa0
set server +3000 <INSERT PASSWORD>
set log Phase Chat LCP IPCP CCP tun command
set speed 115200
set ifaddr 192.168.0.1/0 192.168.0.2/0 255.255.255.0 0.0.0.0
The ppp process was started with the "-dedicated" option from
/etc/rc.local.
This was just a kludge for me until my NICs came in the mail. I found a used pair of 10Bast-T NICs on the internet for the same price as the null modem cable. Wish I'd known that before I bought the cable. Anyhow, best of luck.
