http://www.linuxquestions.org – Dear Slackers, this is not Slackware-specific question, but I am sure somebody will be able to get me the answer. So, let my machine be A, a Linux Server be B, and an ftp server be C. Code: A  -  B  -  C,   ssh    ftp A connects to B via ssh, and B to C via ftp. A cannot directly connect to C. Can I download a file from C directly to A without saving it on B's hard drive? Best regards, Martin (HowTos)
