It seems like cisco's ftp server is a tad buggy. After a number of transfers, it decides that it will no longer play PASV nicely with the other children. Unfortunately, wget doesn't handle this gracefully at all - it tries to drop back to PORT mode - instead it should note that the passive failed, and reconnect and continue from where it's up to. sample command: wget --debug --passive --mirror -np ftp://ftp.cisco.com/pub/mibs/supportlists/ snippets from --debug output follow.
