Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lartc@vger.kernel.org Hi there Dhirendra, : Okay now I put on a rule for FTP port 21 for 100Kbps. Now when I am : retriving data from ftp server I think the port is different when doing : passive ftp transfer. If I am not wrong then a new dynamic port is sent : by the ftp server to the client.. and then client initiates a new : connection on that port and then the real ftp data transfer happens. Yes. I think FTP should be summarily executed. It has been plaguing us since the beginnings of firewalls and NAT. Sadly, another spiritually impoverished but well-known operating system has two basic options for file transfer: HTTP ("the Internet", of course!), and FTP (for experts!). Of course, on the other side of the divide, people (ab)use ssh for all sorts of nefarious purposes....... (anybody remember a recent article in some print periodical detailing NFS over ssh?) There has been discussion on the question of FTP (port/passive) and shaping on this list in the past. Here are some links. See the following threads: http://mailman.ds9a.nl/pipermail/lartc/2001q3/001473.html http://mailman.ds9a.nl/pipermail/lartc/2002q1/002388.html http://mailman.ds9a.nl/pipermail/lartc/2003q1/007498.html See also Eric Leblond's description of usage: http://home.regit.org/connmark.html : My Question is : Now when limiting the bandwidht will htb limit that : data transfer(i.e. the real file transfer) also under 100Kbps or will : that data transfer be not at all affected by the rule..? That depends entirely on how you use the tools above. Take a look at Eric Lelond's description, and let us know if you are successful. : Just a novice question.. but please guide me... This question is in exactly the right forum, and I'm quite sure I wouldn't call it a novice question....though it might well belong in that rumoured FAQ. Good luck, -Martin -- Martin A.
