Package: linuxdcpp Version: 1.0.2-1 Severity: normal When two clients connect to each other through SOCKS proxies and both clients have reverse port forwardings from their respective proxy servers, linuxdcpp detects both users as being in passive mode (firewall icon) and does not attempt to connect them; instead it says "Can't connect to a passive user whilst in passive mode!" to the user.
StrongDC++ detects both users as passive (firewall icon) but still attempts the connection and succeeds. To replicate, do the following for each client: $ ssh -fNT -D [X] -R *:[Y]:localhost:[Y] [us...@[host] - where [host] is a sshd that **has reverse port forwarding enabled.** - /etc/ssh/sshd_config needs to contain "GatewayPorts <no|clientspecified>" - have each client use localhost:[X] as a SOCKS proxy (resolve names too) - have each client listen on port [Y] (X and Y can be different for each client. note that if they are both connecting to the same host, Y *must* be different) the following commands can be used to make sure the reverse tunnel works: client_A$ nc -l -p [Y] client_B$ telnet [host] [Y] B's input should appear as A's output. In this setup, A and B can both receive incoming connections, so both users can be in active mode, even though both are behind proxies. However, if A and B connect to a hub and try to download from each other, linuxdcpp with give the aforementioned error message and aborts the connection, whereas StrongDC++ performs the connection and succeeds. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages linuxdcpp depends on: ii libbz2-1.0 1.0.5-1 high-quality block-sorting file co ii libc6 2.7-16 GNU C Library: Shared libraries ii libgcc1 1:4.3.2-1 GCC support library ii libglade2-0 1:2.6.2-1 library to load .glade files at ru ii libglib2.0-0 2.16.6-1 The GLib library of C routines ii libgtk2.0-0 2.12.11-4 The GTK+ graphical user interface ii libpango1.0-0 1.20.5-3 Layout and rendering of internatio ii libssl0.9.8 0.9.8g-14 SSL shared libraries ii libstdc++6 4.3.2-1 The GNU Standard C++ Library v3 ii libx11-6 2:1.1.5-2 X11 client-side library ii zlib1g 1:1.2.3.3.dfsg-12 compression library - runtime linuxdcpp recommends no packages. linuxdcpp suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
