This is used by the userland PPP software. The number after tun = specifies |A| ... pseudo-device pty # Pseudo-ttys (telnet etc) This is a ``pseudo-terminal'' or simulated login port. It is used by incoming telnet and rlogin sessions, xterm, and some other applications such as emacs. The number indicates the number of ptys to create. |A| ^ after pty ... pseudo-device bpf # Berkeley packet filter This is the Berkeley Packet Filter. This pseudo-device allows network interfaces to be placed in promiscuous mode, capturing every packet on a broadcast network (e.g., an Ethernet). These packets can be captured to disk and or examined with the tcpdump(1) program. Perhaps add a note here: Note: The bpf pseudo-device is also used by the dhclient(8) program to obtain the IP address of the default-router etc. Leave it uncommented if you connect to a network using DHCP. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~= ~ http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-tr= ouble.html 9.6 If Something Goes Wrong =46irst Note: The proper command to ``unlock'' the kernel file that make installs (in order to move another kernel back permanently) is: # chflags noschg /kernel An addition perhaps: If you find you can't do this, you are probably running at a = securelevel(8) greater than zero. Edit the kern_securelevel entry in /etc/rc.conf to kern_securelevel=3D"-1" and reboot. Remember to change it back when = you're happy with your new kernel. J.
