[opensuse] Practicalities of IPv6 - tc does not have IPv6 support?
According to http://lartc.org/howto, tc (traffic control) does not yet support ipv6 filtering. This has the potential to be a significant problem. I use tc/wondershaper to reserve upstream bandwidth for VoIP, but I guess I won't be having enough IPv6 traffic (for a while) for it to cause a real problem. /Per -- Per Jessen, Zürich (12.6°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

There are many other tools that may _potentially_ fail to work with IPV6, not just "tc". good candidates are those that use gethostbyname() #scanelf -lpqs -gethostbyname to get an idea. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What is "scanelf"? cer@nimrodel:~> webpin scanelf No results found for "scanelf" in openSUSE_110 - -- Cheers, Carlos E.

A utility to inspect ELF libraries (just about every library on a modern LINUX system). awilliam@linux-m3mt:~> scanelf -lpqs -gethostbyname gethostbyname /opt/kde3/lib/libDCOP.so.4.2.0 gethostbyname /opt/kde3/lib/libmcop.so.1.0.0 ... Will list every library that uses the "gethostbyname" API. Which will be just about everything network related. But that doesn't necessarily mean that the relevant library, or the application that uses it, will be affected in any real way by the IPv6 bug in gethostbyname [with this bug it is *very* unlikely to have much real-world bite except on really bad code]. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=455762 Note: <quote source="http://sourceware.org/bugzilla/show_bug.cgi?id=5479"> This never worked, people hardly ever use mapped addresses, and gethostby* should not *EVER* be used in the first place. Anything to get people away from gethostby* is a good thing. </quote> This bug has been open since 2007 because it is irrelevant and nobody cares. If nobody every fixes it - it just won't matter. IPv6 works great, there are [of course] a few things still need to get completely up to speed, but there is no significant mainstream block to adoption. -- openSUSE http://www.opensuse.org/en/ Linux for human beings who need to get things done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Very true, but I wouldn't expect many of those to be primarily for network(ing) purposes. /Per -- Per Jessen, Zürich (9.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
