Verify Linux kernel

• The AX.25 stack could have either been built into a monolithic kernel or installed as a kernel module
• Check both of these methods to determine if your kernel is AX.25 ready

grep -i "ax25*" /proc/kallsyms

c03b3654 t bin_net_ax25_table
c03b4154 t bin_net_ax25_param_table

 lsmod | grep -i "ax25"

ax25                   46950  3 mkiss

• Determine your kernel version

uname -r

• As root run the following command replacing <kernel_version_number> with result of above command

insmod /lib/modules/<kernel_version_number>/kernel/net/ax25/ax25.ko

• Add an ax25 entry to /etc/modules to load the ax25 module at boot time
