Alright guys, get ready to point and laugh. I've been using Gnome for
quite some time now and have gotten used to it. Yesterday I tried to
install it on Slackware 11. Several times. In several flavors.

Gware, Freerock, Dropline, and source. I installed the lot.

After I had succeeded in thoroughly screwing up the system, I figured I
was better off with KDE, or better IceWM and Rox or something. So this
is the procedure I took:

as root:

cd /var/log/packages
for a in *dl.tgz; do removepkg $a; done # <- removes Dropline
for a in *Gw.tgz; do removepkg $a; done # <- removes Gware
for a in *frg.tgz; do removepkg $a; done# <- removes Freerock
cd ~/slackware/11.0/slackware
for a in `find . -name *tgz`; do upgradepkg --reinstall --install-new
$a; done

That last should reinstall everything as new, and worked fairly well.
The only problem I'm left with is Firefox and Thunderbird which are
acting as if they have DNS problems.

Thu Nov 02 10:24:38 ~> cat /etc/resolv.conf
search websterscafe.com
nameserver 192.168.1.2

The values here are correct, and lynx and fetchmail have no troubles.
Also, firfox has no problem hitting the websterver inside my firewall,
just sites from outside are unavailable. They die immediately, so it
isn't a timeout, it looks as if *just* mozilla apps cant see the DNS
server, which is also internal.

Oddness.

A little more info. When Firefox tries to load a site outside the
subnet, tcpdump returns nothing. Mozilla apps dont seem to even hit the
TCP/IP stack, but only when using DNS. Hitting google by IP addy works.

Maybe strace will be able to give you a clue about what is going on. This
is an example with lynx:

$ strace -f lynx -dump http://www.google.com >& /tmp/lynx.trc
$ fgrep open /tmp/lynx.trc | grep resolv
[pid 32211] open("/etc/resolv.conf", O_RDONLY) = 3
[pid 32211] open("/usr/lib/qt-3.2.1/lib/libresolv.so.2", O_RDONLY) = -1
ENOENT (No such file or directory)
[pid 32211] open("/lib/libresolv.so.2", O_RDONLY) = 3

As the logging from strace gives a lot of output it is a rather good idea
to send it to a file for later analysis.

wget seems to be exhibiting the same behavior as the mozilla apps. The
similarities in dumps between wget and firefox is as such:

---------------------
open("/usr/local/qt/lib/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No
such file or directory)
open("tls/i686/sse2/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such
file or directory)
open("tls/i686/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
open("tls/sse2/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
open("tls/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("i686/sse2/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file
or directory)
open("i686/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("sse2/libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("libnss_files.so.2", O_RDONLY) = -1 ENOENT (No such file or
directory)
----------------------

Subsequent investigation shows:

Thu Nov 02 11:51:13 ~> locate libnss_files.so.2
/mnt/distro/lib/tls/libnss_files.so.2
/mnt/distro/lib/libnss_files.so.2

/lib/libnss_files.so.2

WTF?

Think it could be a qt problem?

That is odd.

Is it possible that one of your gnome installs removed the stock
slackware package and installed their own and your removepkg scripts
didn't get rid of them? This seems at least semi-likely.

I would removepkg your firefox, thunderbird, mozilla, whole nine yards
and then re-install them with installpkg.

The behavior is exhibited by wget as well, so I'm thinking it's a lib
issue. Example:

-------------------------------------

Notice the cookie attempt as well which seems to be rejected by wget.
I've reinstalled all libs from original packages using:

updatepkg --reinstall --install-new

with noticeable results on previously misbehaving applications.

There are some unexpected things, like lynx.cfg being replaced by the
stock version, so I'm unsure as to the overall state of /etc. Package
installations are usually kind to custom config files though.

Note: I replaces all packages, not just slackware/l.

And a little more info. Wget is experiencing the same problems as
firefox and thunderbird. By extension: Fix wget == fix
firefox/thunderbird.

Maybe.

Setting wget explicitly to IPv4 works! From this the assumption can be
made that wget (and hopefully firefox and TB) are using IPv6 by default,
screwing up the system in this so far unexplained way. Since the problem
is affecting just these programs and not others, we can also assume a
library shared by these programs (but not others) is the culprit.

This looks to be a long night.

It is normal behavior that a program tries to open shared libraries trying
your entire LD_LIBRARY_PATH and paths from ld.so.conf untill it succeeds.
/lib and /usr/lib is searched last. For more info on how this works you
can see the manpage of ld.so.

> Thu Nov 02 11:51:13 ~> locate libnss_files.so.2

> /lib/libnss_files.so.2

The important thing is if your program later was able to find
libnss_files.so.2 in /lib. If it didn't search in /lib you might have a
broken binary linked with -z nodeflib.

This looks odd, but I don't think it explains your wget problems. My guess
is that /usr/local/qt/lib only contains a single file which is a symbolic
link pointing to /usr/local/qt/lib.

What did you expect to have in /usr/local/qt? Your Slackware probably
already has a /usr/lib/qt-<version>/lib which should contain a working qt.
Did you upgrade to a newer qt which you placed in /usr/local? My guess is
that you can remove the directory /usr/local/qt and remove the line
/usr/local/qt/lib from /etc/ld.so.conf. However, I don't think this solves
your problem.

Yes.

But.

If I issue, as root, `rmmod -wf ipv6`, the module is not removed as it
is in use, but the apps start working again.

It's enough to make me give my head a shake to make sure everythings
working. I originally thought removing vmware had solved the problem,
but issuing the above command was part of the process.
