NoCatSplash and Cheshire
If you need a simple “splash screen” for your wireless users, try either of these simple captive portals.
Some people find that Perl is too heavy of a requirement for their gateway hardware, making it impractical to use NoCatAuth. If you are only looking for a “click here to continue” sort of splash page (without the full authentication mechanism), you may be interested in NoCatSplash.

/usr/local/sbin/, and puts the
nocat.conf configuration file in
/usr/local/etc/. Edit the
nocat.conf file to your tastes, taking note to
set the ExternalDevice, InternalDevice, LocalNetwork, and DNSAddr
options to fit your network layout. See the comments in the
configuration file for details.
Start the portal by running splashd as root:
root@florian:~# /usr/local/sbin/splashd &NoCatSplash uses the same firewall scripts as NoCatAuth to do the
actual firewall manipulation. It installs these scripts to
/usr/local/libexec/nocat/ ...
