Package: vnc4server Version: 4.1.1+X4.3.0-32 Severity: normal
I tried using 4.1.1+X4.3.0-34 but it would only bind to the IPv6 port. After reverting, I read the bug report for #550789. It looks like the patch respects the value of /proc/sys/net/ipv6/bindv6only, which the submitter claims defaults to 0. I have an /etc/sysctl.d/bindv6only.conf (which doesn't seem to belong to any package) which states the following: ---- # This sysctl sets the default value of the IPV6_V6ONLY socket option. # # When disabled, IPv6 sockets will also be able to send and receive IPv4 # traffic with addresses in the form ::ffff:192.0.2.1 and daemons # listening # on IPv6 sockets will also accept IPv4 connections. # # When IPV6_V6ONLY is enabled, daemons interested in both IPv4 and IPv6 # connections must open two listening sockets. # This is the default behaviour of all modern operating systems. net.ipv6.bindv6only = 1 ---- Now, I don't have any reason to retain that file that I know of, but my concerns are two-fold: 1) some package has created this file at some point 2) the comments suggest that opening a socket per protocol is the normal method for programs So, I believe if this patch is left in the state it is in, a note needs to be made about its interaction with net.ipv6.bindv6only in the README.Debian file. -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.31-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages vnc4server depends on: ii libc6 2.10.2-2 GNU C Library: Shared libraries ii libgcc1 1:4.4.2-3 GCC support library ii libstdc++6 4.4.2-3 The GNU Standard C++ Library v3 ii libx11-6 2:1.3.2-1 X11 client-side library ii libxext6 2:1.0.4-1 X11 miscellaneous extension librar ii libxtst6 2:1.0.3-1 X11 Testing -- Resource extension ii x11-common 1:7.4+4 X Window System (X.Org) infrastruc ii xbase-clients 1:7.4+4 miscellaneous X clients - metapack ii xserver-common 2:1.6.5-1 common files used by various X ser ii zlib1g 1:1.2.3.3.dfsg-15 compression library - runtime Versions of packages vnc4server recommends: ii xfonts-base 1:1.0.0-6 standard fonts for X Versions of packages vnc4server suggests: pn vnc-java <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
