I believe I have found a bug in wu-ftp version 2.6.0-14. I am running Redhat version 6.2. Wu-ftp does not work when the ftp server has a 127 in the third octet of the ip address. When you ftp to the server you receive a message stating you are connected but are never prompted for a user name or password. It does eventually time out. As soon as I change the ip address to something other than x.x.127.x it works fine. Would you please confirm my results.
Can't confirm this - you're probably seeing a reverse DNS lookup hang because your x.x.127.x network doesn't have a reverse DNS setup?
