I just typed under
"dconf-editor", System → Proxy → ignore-hosts, the following content:
['localhost', '127.0.0.0/8', '::1', '192.168.0.1', '2000::/3', 'fc00::/8']
But, Google Chrome (and
apt-get update / upgrade) is just ignoring this settings.
EDITED: Also, Firefox doesn't honor the
ingore-hosts settings, even configuring it to "Use system proxy settings".
For example, my Proxy Server (Ubuntu with Squid3) is in dual-stacked mode BUT, I do NOT want to access IPv6 web sites through the Proxy, that's why I'm trying to ignore the entire IPv6 Internet with the entry
2000::/3, but, it does not work as expected.
EDITED: Also, I don't need the proxy to access
Hyperboria sites, which resides under
fc00::/8 but, it doesn't work either...
Why I'm doing this?
Because my environment is already a IPv6-Only Network and, to access the old internet infrastructure (IPv4-Only), I need to go through the dual-stacked proxy. But I need the proxy only when a web site doesn't have IPv6...
How can I know that it doesn't work?!
It is simple, just access a web site that shows a IPv6 address on it, for example,
http://ipv6.whatismyv6.com, then, I'm still seeing the IPv6 address of the Proxy Server, so,
"ignore-hosts entry '2000::/3'" doesn't seem to be working.
EDITED: Plus, when I'm trying to access a
Hyperboria website, Squid returns an error that it can not reach
(Squid ERROR: (101) Network is unreachable)
(of course it can't, the
cjdns router is running right on my Ubuntu Desktop, so, no need to go through proxy when browsing
Hyperboria fc00::/8 but, Ubuntu isn't honoring
ignore-hosts under proxy settings.
