8. Problems.

The glibc package contains a FAQ with additional information that you should check if you are having problems. An online version is also available at http://www.imaxx.net/~thrytis/glibc/glibc-FAQ.html. Below are some tips for solving problems which are not covered in the FAQ or are covered here in more detail.

8.1 Host names do not resolve.

Glibc 2 uses a different method than libc 5 in looking up host names. The glibc name server switch (NSS) code looks for a file /etc/nsswitch.conf. If host names are not resolving for you when using a glibc 2 application and your /etc/resolv.conf is configured correctly, check if you have the /etc/nsswitch.conf file. If you do not have this file, you can create one containing the line:

 hosts:        files dns
 

It will now look for /etc/resolv.conf to find the nameservers.

You should look at the section of the libc info pages describing the nsswitch.conf file for more details.
