To install as a Loadable Kernel Module (LKM): 1. do a "make sunos4" in this directory 2. Run the script "SunOS4/minstall" as root. 3. change directory to SunOS4 and run "make install" 4. Reboot using the new kernel 5. use modload(8) to load the packet filter with: modload if_ipl.o 6. do "modstat" to confirm that it has been loaded successfully. There is no need to use mknod to create the device in /dev; - upon loading the module, it will create itself with the correct values, under the name (IPL_NAME) from the Makefile. It will also remove itself from /dev when it is modunload'd. To install as part of a SunOS 4.1.x kernel: 1. do a "make sunos4" in this directory 2. Run the script "SunOS4/kinstall" as root. NOTE: This script sets up /dev/ipl as char. device 59,0 in /sys/sun/conf.c 3. Do "mknod /dev/ipl c 59 0" as root. 4. Reboot using the new kernel Darren Reed darrenr@cyber.com.au
