while (!feof(proc) && (fscanf(proc, " %15[0-9.] %*s %*s %17[A-Fa-f0-9:] %*s %*s", ip, mac) == 2)) {

Change the original line to that and it solves the problem.

This is a duplicate of #493. I can not find any kernel which lowercases MAC addresses, and I find it very hard to believe that any Linux kernel would change its ABI like that. I checked several ia32 2.6 kernels and an OpenWRT 2.4.30 kernel, all of which have uppercase entries.

Unless you can point us to a kernel that shows this behaviour I'm marking this as wontfix.

Please, before you mark it as wontfix, ask in the wifidog mailing list if anyone can point to the source of the problem commented here. If I don't apply this patch, wifidog won't work in openwrt with kernel 2.6.26.5. Maybe is not the kernel, maybe yes. But the truth is we need the patch. Besides it will prevent futures problems of this kind :)

Hello all,

I found a kernel that has lowercase mac addresses in it.... Mac OS X!!! I've been pulling out my hair for 3 hours trying to figure this one out. My authentication fails with the output of mac 00:17 that should be 00:17:f2...

Actually, this was also broken in Ubuntu Intrepid. Fixed in [1389]
