The problem is not in ftp-gw or http-gw. The problem is in your inetd.conf.
The sample inetd.conf from TIS doesn't work under Linux (I don't know why).
The inetd is not setting up the argv/argc properly when it calls ftp-gw
and this causes ftp-gw to hiccup. All you hafta do is add the name of the
executable to the end of the configuration line in inetd.conf, which gets
passed to ftp-gw as argv[0]. Like this:

ftp stream tcp nowait root /usr/sbin/ftp-gw /usr/sbin/ftp-gw
#                                           ^^^^^^^^^^^^^^^^
#                                           this gets passed to ftp-gw as argv[0]

Substitute whatever directory you use for /usr/sbin.

I fought almost half a day with this one. Thought I had really messed up!
