advanced stuff: ipv6 workbench/1st results sysupdate and mail needs ping?
Posted 04 December 2004 - 01:49 AM
once again i am getting on your nerves. :cheesy:/> i have worked hard and wrecked several linux-installations these last days/weeks in order to find a solution for the bloody ipv6 problems (on routers) many users have. this time, i did the following:
i installed fedoracore3, mandrake 10.1, ubuntu, kanotix and yoper on a desktop-pc and a laptop, in order to make sure the problems are not only distro related. on each of these boxes, i deactivated ipv6 for the browser and deactivated (o rather tried to) it on the global network, too. i added /changed the follwing files:
/etc/sysconfig/network, added "NETWORKING_IPV6=0"
/etc/sysctl.conf, changed to "ipv4.icmp_echo_ignore_broadcasts=1" and "ipv4.tcp_window_scaling=0"
/etc/modprobe.d/aliases, (on debian based systems) changed to "alias net-pf-10 off"
also set the ipv6 usage to "no" in the /etc/ppp/ipv6-up and ipv6-down files.
(also tried alternative packages for dnsresolving and dhcp-server use)
webbrowing works this way without mayor hassles. the only thing that does not work well, especially on laptops is fetching mail or updating systems. i tried several mail-clients and used apt-get, yum, urpmi and up2date. i was not able to reach the mirrors/servers if i did not open a terminal at the same time, pining directly at the server/mirror, prior to starting the mail or updating tools.
now, the dramatic question is: why does ipv6 blocking work on the web but not with mail/updating? is there another file that i forgot to change? if not, why are these two things handled differently? :huh:/>
i think there must be a way to solve this problem but i must say, it is getting more complicated the more i check the systems. it is not frustrating, but i guess it is starting to get over my head... :wacko:/>
any ideas for discussing this/solving this problem together would be nice. 100 brains think faster than one brain. ; )

i know, only few people might know an answer but this topic is not about seeking an immediate answer but a workbench and it would be nice to hear some input.
on the ipv6 stuff: i thought that maybe changing some scripts in the /etc and /sbin folder could help, but i am not sure at all. maybe hacking one file will cause a chain-reaction so that i might need to change dozens of scripts or might destroy the box altogether :D/>. (i would need an old, unneeded box for that i guess)
... if someone would pay me the time used on this problem, i would be richer than bill gates. :P/>
