Description Den...nis He..u..er 2008-01-08 04:45:40 CET

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9b2) Gecko/2007121914 Minefield/3.0b2
Build Identifier: 

This strange error message ("could not look up internet address for Foo")
occurs just for so at startup, which means that /etc/hosts is correct and that things worked at earlier time.

I know this problem from a previous gnome installation and have it now with
Xfce. The first time I was able to solve the issue by exchanging the util-linux
login with the shadow-passwords login. However, I never understood this issue
because the network is accessible, the desktop works and internet works too.
This time the problem occurred 'suddenly' after an xorg update. A re-install of Xfce didn't help. Can you please tell me what the matter is (what the session manager asks the xorg server and why this may fail?)

My network is routed via a DSL-Router. The ifconfig is as follows:

Assuming that "Foo" is your host name (the name returned by gethostbyname), then this messsage tells you, that this name cannot be resolved using the libc DNS resolver (most probably a broken /etc/hosts, but that's not the only possible cause). This is a safety check in xfce4-session to ensure that your environment is sane, because otherwise applications will not be able to connect to the session manager at all.
