Bug 83667

      1. I can log in one ftp server successfully, but i can NOT see any directories or files. Also, I can NOT download any files from any ftp server.
2. I run "make install clean" in any ports directory, for example, /usr/ports/ftp/lftp/, there was one error "No route to host". The history log was listed below:

# make install clean
===>  Vulnerability check disabled, database not found
=> lftp-3.0.13.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/.

^Cfetch: transfer interrupted

How-To-Repeat:       Go to one ftp server and try to download some files.
