Hello there! Thank you very much for your reply, Ernst! I am sorry but I couldn't understand exactly what is the problem and how do I fix it... I did build my kernel from source, doing the things recommended in readme.redhat of nistnet: turn off module versioning and install the enchanced real time clock support as module
Also before making nistnet i had to - apply a patch before making nistnet as in: http://www.stabellini.net/nistnet.html - change the code of nistnet_table.c myself (This is because I am using a more recent kernel (2.6.22-9) than the patch is good for, and there was a modification on the kernel I use... I can get you more details if you want) I am not a linux expert, so it's possible I made some mistake in these steps... To call nistnet, I do make the famous steps of: mknod /dev/hitbox c 62 0 mknod /dev/nistnet c 62 1 chown root /dev/hitbox chown root /dev/nistnet mknod /dev/mungebox c 63 0 chown root /dev/mungebox mknod /dev/spybox c 64 0 chown root /dev/spybox and then I do a: rmmod rtc modprobe nistnet cnistnet -u my output for: cnistnet -G is: Emulator is: On Average processed packet overhead 3 usec Average unprocessed packet overhead 3 usec Average hash tries 0 The command: cat /proc/interrupts shows 0 interrupts for irq 8. I can see this is a problem, but I don't know why this happens, and neither how to fix it... Thank you for your patience!
