Hi
I used fedora 6 connected to the internet where its gateway was a WIN xp machine with ICS enabled and all worked fine.
I changed my DSL modem to a router configuration and connected both computers to the router with a switch.
I had to disable ipv6 explained here:
(http://www.mjmwired.net/resources/mj...-fc6.html#ipv6)
and i can see the internet OK,but, Evolution mail can't connect anymore,yum and wget aren't working,terminal SSH also and who knows what else...
this is what i get from yum:
[root@fedora6 etc]# yum search java
Loading "installonlyn" plugin
Setting up repositories
Could not retrieve mirrorlist http://mirrors.fedoraproject.org/mir...re-6&arch=i386 error was
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Error: Cannot find a valid baseurl for repo: core
I can open the site with firefox and if i change the siteś name to itś IP in yum confand uncommented the base urls in yum conf files then i get this:
ok, if you can reach the internet ok, can you go to "http://mirrors.fedoraproject.org" in firefox? are you using a proxy to do this? if you can successfully see that webpage but yum is failing to reach the same site, it'd have to be a proxy issue i'd be sure. what does the contents of /etc/resolv.conf say about your cojfigured name servers? can you ping the name servers? can you do a dig or host lookup against them explicitly, e.g. "dig google.com @12.34.56.78"?

Rep:
Either you didn't follow the steps exactly to disable IPv6, or you manually edited a file and made modifications you're not revealing. It sounds like either you edited /etc/services and removed/commented some lines, or that the resolver libraries are expecting IPv6 support to be present and it's not. Have you checked your interfaces to see if they're getting IPv6 addresses? That might be causing a problem if your primary interface still has an IPv6 address but the support for it is turned off.
BTW, this is a good example of why "tuning the kernel for performance" is generally a bad idea. Unless you know exactly what you're doing, trying to remove default pieces (especially as big a piece as IPv6) is just going to cause problems, and for very little potential gain. My recommendation would be to just IPv6 on and have the opportunity to learn about it as it's rolled out to more sites over the coming years. The US goverment for example has a huge push for IPv6. I believe they're even mandated to have all software support IPv6 within 2 years.

I had to disable ipv6 or i can't connect at all,looks like my isp doesn't support ipv6 yet.
