IS passive mode on or off with this wu-ftpd configure.in statement?

Debbie Fleith — Fri, 21 Mar 2008 14:06:59 GMT

I need to figure out if our wu-ftpd daemon is configured for active or passive mode. I found this within the configure.in file, but can't decipher is, as I'm not a C programmer.

Can anyone help?

AC_ARG_ENABLE(pasv, [ --disable-pasv don't allow passive mode],
[ pasv=$enableval ], [ pasv=yes ])

The configure.in is used by autoconf and is generated when you run ./configure. Unless you have specified --disable-pasv, it will have pasv enabled. As you can see in that file, the value for pasv=yes, that is the default.

Is there a way to change the default without re-compiling, i.e. can we add a server argument to /etc/xinetd.d/wu-ftpd?

Don't think "default" as the mode used by the clients. In this case, default means that the feature is enabled "by default". If you disable it, then passive support is removed.

The connection mode is established by the client and "supported" by the server. From the server, you can't "force" a client to start in a specific mode if that is what you want.
