Kernel PPP does not work right now, but uerlevel PPP offers much more features (channel-bundling, dialin support, etc.) and works fine for me. You'll need to compile your own userlevel ppp daemon since the version OpenBSD is shipping does not support HDLC or isdnd-signaling.

3 - Downloading files

This stuff applies against OpenBSD 2.8 (actually OpenBSD-20010116) and Isdn4BSD-00.90.00-beta-111299.
As stated earlier you need to compile a new version of the userlevel ppp daemon since the one OpenBSD is shipping does not support HDLC and isdnd signaling.

• The patch against i4b-0.90.00-beta-111299: i4b-0.90.0-OpenBSD-20010116.patch
  (complete patched version: i4b-0.90.0-OpenBSD-20010116.tar.gz)
• Patch against FreeBSDs userlevel ppp-daemon: ppp-OpenBSD-20000608.patch
  (complete patched version: ppp-OpenBSD-20000608.tar.gz)

4 - Step by step installation

# cd /usr/src
# tar -xzf ~/i4b-0.90.0-OpenBSD-20010116.tar.gz      # unpack patched i4b sources
# cd i4b/OpenBSD
# more INSTALL                                       # READ !
# sh ./install-openbsd.sh
# cd /dev; sh /usr/src/i4b/OpenBSD/MAKEDEV.i4b all
# [EDIT YOUR KERNEL CONFIG] && [BUILD KERNEL] && [INSTALL KERNEL]
# cd /usr/src/i4b
# cp -Rp machine /usr/include/i4b                    # IMPORTANT !
# cd /root
# tar -xzf ppp-20000608-OpenBSD.tar.gz               # unpack patched ppp sources
# cd ppp-OpenBSD
# make && make install

Reboot, read 'man ppp', 'man isdnd', 'man isdnd.rc' etc.
   

set device /dev/i4brbch0
set speed sync
   

5 - Example configuration

• /etc/ppp/ppp.conf,
• /etc/isdn/isdnd.rc
• and last but not least a kernel configuration file for a box having a Fritz!Card PCI: ISDNKERNEL
• Here's an example for setting up logging and integrating isdnd into the boot sequence:
  
  Add this to your /etc/syslog.conf:
  

  local2.info                                             /var/log/isdnd
         
  

  And do a:
  

  # touch /var/log/isdnd
         
  

  Include the following line in /etc/newsyslog.conf for logfile rotation:
  

  /var/log/isdnd l                         600  10   *    168   Z
         
  

  And finally start isdnd in rc.local:
  

  # Starting isdnd.
  if [ -x /usr/local/bin/isdnd ]; then
           echo -n ' isdnd';
          # -d0x95 is a quite verbose debugginglevel
          # -s 18 corresponds to syslog facility local2
          # -s 3 would enable logging to /var/log/daemon just like ppp
          /usr/local/bin/isdnd -d0xf9 -s 18
  fi

6.1 - Dialin configuration

# cd /usr/src/i4b/user-ppp
# make
# cp i4brunppp /etc/isdn
# cp i4brunppp.cat8 /usr/share/man/cat8/i4brunppp.0
