>From the configuration in the aforementioned guide:

server {
listen 127.0.0.1;
server_name localhost;

access_log /var/log/nginx/localhost.access_log main;
error_log /var/log/nginx/localhost.error_log info;

root /var/www/localhost/htdocs;
}

This specifically instructs nginx to listen only on 127.0.0.1, so even
connections from the same machine to its hostname or external IP
address will not hit nginx there. You'll need to change the 'listen'
value to determine what connections it should be answering. See the
nginx documetation on that here:

http://nginx.org/en/docs/http/ngx_http_core_module.html#listen

I would suspect for your internal network use-case, you'll want:

listen *:80;

I think you are right.  While youtube and some other video sites worked
fine with the very new version, it appears I have at least one site I
visit that wants the old version.  I use a .gov website for my weather
radar.  Without the slot 0 version, it wouldn't load.  Once installed,
with the newer slot 0 version, it worked fine. 

I think the reason I, and maybe the OP as well, got the error message,
since neither of us had it in the world file, it wasn't getting updated,
even tho one was available.  So, we do need to add it to the world file
IF we use any sites that require the old version instead of the new and
much improved crap that youtube and some other sites uses.  ROFL  I
couldn't pass it up.  Sorry.  That way both slots gets updated and not
just the latest and greatest crap. 

I just realized that this is off list.  You may want to add this to the
thread for the OP.  Plus, it may help someone else reading this as
well.  If you want, just forward this email to the mailing list.

[gentoo-user] How to get nginx serving pages?

[Peter Humphrey]

Hello list,

Several years ago I set up an apache2 web server to host a development site, 
and I had quite a struggle to get it all set up. Now I want to do it again, 
but I decided to try nginx instead. I've followed the instructions here:

https://wiki.gentoo.org/wiki/Nginx

...but I get Connection Refused in www-client/links running on the same 
machine, or in Firefox over the LAN. I can run links as myself or as root, 
with the same result. But:

$ curl http://localhost
Hello, world!

# netstat -tulpen | grep :80
tcp  0  0 127.0.0.1:80  0.0.0.0:*  LISTEN  0  60680  19196/nginx: master

/etc/nginx/nginx.conf is untouched since installation.

Shorewall isn't logging anything.

What have I overlooked?

[gentoo-user] s3tc enable for Firefox 49?

[Miroslav Rovis]

Hi!

I'm not sure, but I've been struggling with this bug:

media-libs/mesa-13.0.0_rc2: libGL crashes on hardened AMD64
https://bugs.gentoo.org/show_bug.cgi?id=598593

( my duplicate is at:
=www-client/firefox-49.0 segfaults with >=media-libs/mesa-13.0.0_rc1 on
>=4.4.8-hardened-r1
https://bugs.gentoo.org/show_bug.cgi?id=598700
)

and it looks like (I had better show you the standard output when
starting firefox 49.0 on plain 4.8.3 kernel:

ATTENTION: default value of option force_s3tc_enable overridden by
environment.
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.
1478449652215   addons.productaddonsWARNFailed downloading XML,
status: 0, reason: error

(firefox:5208): GLib-GIO-CRITICAL **: g_loadable_icon_load: assertion
'G_IS_LOADABLE_ICON (icon)' failed

and a few more lines to that effect.

After some ducking for info I see that:
https://en.wikipedia.org/wiki/S3_Texture_Compression
is mostly used for games (and I'm not a gamer.)

But it looks like, apart from mesa alleged fix (see in the bug report)
not having propagated to us, [it looks like] that s3tc functionality is
missing for my Firefox to behave...

There have been various tips in the various distro flavors about
enabling s3tc, but I couldn't get it to work in Gentoo.
Such as after emerging:

# emerge media-libs/libtxc_dxtn

and issuing:

$ force_s3tc_enable=true firefox

That still got me the line:

ATTENTION: default value of option force_s3tc_enable overridden by
environment.

Also, the useflag:

https://packages.gentoo.org/useflags/s3tc

only has:

app-emulation/wine

as sole customer at this time...

I wasn't sure this was a post for the bug report that I linked to above, so I'm 
asking here on the users list.

Anyone has any more clue about this issue?

Regards!

There is a site that lists what files you can remove and not lose all
data.  If you google for it, it's something like mozzilazine or
something.  I use Seamonkey for my email so I'm always careful with
deleting that directory since I'd lose all my emails.  Of course, if you
don't use the email part, it won't matter.  Just may want to save those
bookmarks first.
