Upload some version of truss compiled for FreeBSD 4.x (e.g.
http://m0n0.ch/wall/downloads/truss) through exec.php, mark it as
executable and run it on the PID of the captive portal mini_httpd
process (i.e. /path/to/truss -o /tmp/truss.log -p <mini_httpd-pid> &).

Another thing to try would be to kill the captive portal mini_httpd,
upload the mini_httpd that comes with 1.2b3 (pull it out of
rootfs-1.2b3, usr/local/bin/mini_httpd), rename the existing
mini_httpd to something else, copy the uploaded mini_httpd to the
original location (/usr/local/bin/mini_httpd), make sure it's marked
as executable, and hit "save" on the captive portal page to make it
start again.
