 Posted: Tue Sep 02, 2008 8:52 pm Post subject: [SOLVED] Weird DNS resolver issue by some apps |
 |
|
Hi,
for 1-2 months I'm experiencing that some apps are not able to resolve hostnames.
Examples of issue:
* liferea:
| Code: | | "The last update of this subscription failed! HTTP error code 0: Hostname could not be found" |
* layman, when trying to fetch overlay list (layman -f)
| Code: | * Failed to update the overlay list from: http://www.gentoo.org/proj/en/overlays/layman-global.txt
* Error was:
* <urlopen error (-2, 'Name or service not known')> |
Apps, that I use, not having this problem: PSI, Evolution, Xchat
So I think that this must me a system-wide problem.
Before this problem appeared I tried 'emerge --depclean' and upgrading to GCC 4.3. Then I downgraded back to GCC 4.1 and did 'emerge -e system' and world. But It didn't helped. I don't know what another I can do.
My configuration:
| Code: | Portage 2.1.4.4 (default/linux/x86/2008.0/desktop, gcc-4.1.2, glibc-2.6.1-r0, 2.6.27-rc5 i686)

Try using the "emerge wrapper" in my signature to properly rebuild your toolchain. You should never upgrade or downgrade GCC without upgrading/downgrading/rebuilding the toolchain. If I remember right, the command is:

Yup, you need to rebuild the tool chain, _then_ rebuild system then world. Do a gcc-config as appropriate, then
| Code: | | env-update && source /etc/profile && emerge -1 libtool && emerge -e system && emerge -e world |
.
You probably want to do it in stages instead of using the conditional statement above, chances are that one or two emerge's will fail.
Cheers,

Thanks for your help, but recompiling whole gentoo didn't work.
The problem with liferea and layman remains.
All what I did:
1) ./emwrap.sh -wuDb
2) recompiled toolchain ( ./emwrap -Sb )
3) recompiled system ( ./emwrap -se )
4) recompiled world ( ./emwrap -we )
During recompilation I've noticed python error messages like this:
| Code: |
* Byte compiling python modules for python-2.5 .. ...
Compiling /usr/lib/python2.5/site-packages/Cheetah/Tests/NameMapper.py ...
File "/usr/lib/python2.5/site-packages/Cheetah/Tests/NameMapper.py", line 15
from __future__ import generators
SyntaxError: from __future__ imports must occur at the beginning of the file
|
Do you have please any other idea or direction? I'm being a bit hopeless.
Do you think that recompile whole gentoo with libtool 2.2.3 instead of 1.5.26 could help? |

I've solved this problem by deleting "almost" files from folder /etc and
then I have emerged again toolchain, system, world.
During emerging all default configuration files in /etc were recreated. |
