the problematic ftpd from strato-hosting announces himself as: 214- ftpd.bin - Round-robin File Transfer Server, version 3.4.0r8 (C)1997,1998,1999 by Marc Huber <marc@sixpack.de> ervin Re-assign, assignee is retired. The net-misc/mirror package has been removed. |
Since it is not solved for quite a while I'll try my first Bug-Report, my fist diff and I would appreciate if it will find its way into Gentoo. The Problem: Most ftpd answers "227 Entering Passive Mode" followed by one Space and some data. Some ftpd answers "227 Entering Passive Mode" followed by two Spaces and some data, e.g. Websites hosted by www.strato.de. mirror 2.9 expects exactly one space between that answer and the data, so connections to some ftpd fails because the Information behind those space is not recognized. The solution is small, in /usr/lib/mirror-2.9/ftp.pl line 489 the space in the testing and parsing regex has to be changed from ' ' to something like '\s+' (one or more whitespace). running diff /modified/ftp.pl /path/to/original/ftp.pl shows this: 489c489 < if( $response =~ m/^227 Entering Passive Mode\s+\((\d+),(\d+),(\d+),(\d+),(\d+),(\d+)\)/ ){ --- > if( $response =~ m/^227 Entering Passive Mode \((\d+),(\d+),(\d+),(\d+),(\d+),(\d+)\)/ ){ That might conflict with FTP-RFCs (I do not know) but it works for me. Ervin Reproducible: Always Steps to Reproduce: 1. Try to mirror via ftp a website hosted by strato 2. 3. Actual Results: mirror hangs at 150 Opening ASCII mode data connection.
