>Description:
      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
