I am a new comer in the wireless network. i would like to build portal captive system for wireless network in my campus.

For additional information i use Linux Fedora Core 3, gnupg-1.4.3 (for gpgv) and NoCatAuth-nightly.

After make install gnupg, and walk through to the next step ( building the gateway):
# make gateway (ofcourse i change my diretory first to the NoCat's extract directory)

And then the trouble comes..
The terminal view like this:

# make gateway
Looking for gpgv...
Checking for firewall compatibility: No supported firewalls detected! Check your path.
Supported firewalls include: iptables, ipchains, ipf, pf.
Can't seem to find supported firewall software. Check your path?
make: *** [check_fw] Error 255

I've tried to checked my iptables status (#service iptables status) and Linux displayed that iptables have already running.
I also have checked PATH (echo $PATH)

And displayed:
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:
/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin

I confused why NoCat can't seem to find firewall software in my computer.

Can anybody help me??? please...
Thank before..

Have you asked this on one of the mailing lists for NoCatAuth? If you don't get an adequate response here, I would do so.

I have no idea about this, but I did find this reference about the issue.
