Hi

I had trouble coonecting to the internet after doing a fresh install of Gentoo. I use Wicd, a GUI network manager to connect to my wireless network. initially Firefox would not connect to any website, though I could successfully ping google as well as gentoo. I googled for it, and found that I had wrong IPV6 settings. I took a shotgun approach to this, and tried all the following settings.
Quote:

1. added " alias ipv6 off " " alias net-pf-10 off " to /etc/modprobe.conf

2. Opened "about:config", filter by ipv6 and set it to true
3. /etc/hosts changed (IPv6 section)

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
#ff00::0 ip6-mcastprefix
#ff02::1 ip6-allnodes
#ff02::2 ip6-allrouters
#ff02::3 ip6-allhosts



After all this at some point, Firefox was able to connect to the internet. However I still cannot use emerge anything. I get this error with any emerge command....

I have tried searching the forums and tried some suggestions like adding another nameserver to resolv.conf, but nothing helps. I know for sure that i have a correct resolv.conf as i can get the wifi to connect, and also now am able to browse using firefox.

Any help is appreciated.

Portage uses wget to download the files. Maybe you installed wget with ipv6 USE flag?

Can you post outputs from 'emerge -pv wget' and 'emerge --info'?

Two possible things you can do in my mind.

1.)Remove ipv6 from your use flags in make.conf and recompile.
2.)Specify specific Use flags for wget and recompile

Thanks for the solution... I recompiled wget using -ipv6 as an USE flag... And I am now able to emerge and compile away, as usual.

But what is this ipv6...? and by disabling this will my system be short of critical functionality...?

http://en.wikipedia.org/wiki/IPv6

In short, it's a new system to replace the current set of IP addresses because apparently we are running out ;)
