It has never been able to work through the Squid proxy except for HTTP. I've used WGET, Web Downloader For X, and several other tools to use ftp + http without a problem, has anyone else had this problem?
alias lftps='lftp -e "set ftp:proxy 192.168.168.253:3128 && set hftp:proxy 192.168.168.253:3128 && set http:proxy 192.168.168.253:3128"' Only HTTP works through lftp.
