Is the z90crypt module loaded?
From the "Device Drivers, Features, and Commands" book (page 250 in mine):
"If z90crypt detects at least one CEX2C card capabile of generating long
random numbers, a new miscellaneous character device is registered and can be
found under /proc/misc as hw_random. The default rules provided with udev
creates a character device node called /dev/hwrng and a symbolic
link /dev/hw_random pointing to /dev/hwrng."
Hmm... That's for SLES 11, apparently. I looked in an older copy of that
book and it doesn't mention any of those paths. So if you're using an older
kernel, and the z90crypt module is loaded, you may have to make the device by
hand. The major device number is that of the "misc" device, as shown
in /proc/devices. The minor number is that of the "z90crypt" device
in /proc/misc. With those values, you can then do:
mknod /dev/hw_random c [major] [minor]
to create the device node you need.
