Hi Jochen, thanks for the code, but I am still stuck. I tried your code (with some help compiling provided by my UNIX SA ;-)) and I get core dumps for any of the tried options with both the old enabler code and the new enabler code. Below is /var/log/messages and my attempt with the new code. It does look like my MAC address is within the problem range.

More: What version Re: Sad: tried code but no go, MAC address within problem range (Matthew Austin) Date: 2000, Mar 31 From: Jochen Friedrich jochen1

Hi Matthew, what version of linux, libc and gcc are you using? Did you run the program as root (it needs root for ioperm() to enable user space I/O access)? Do you have a chance to add "-g" to your compile parameters and run gdb ./fa_select? (Then do a "run eth0 0" and record the result of "bt"). Anyways, I placed a binary (needs glibc 2.1) on http://www.gxsnmp.org/fa_select -- Jochen

1. Sad: still no go even with your binary . . . here's the details by Matthew Austin, 2000, Mar 31 2. ioperm() vs iopl() issue by David Hinds, 2000, Mar 31 1. Agree: success!!!!!!!! by Matthew Austin, 2000, Apr 01
