Problems.</A></H2> <P> <!-- glibc!problems --> <P>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 <A HREF="http://www.imaxx.net/~thrytis/glibc/glibc-FAQ.html">http://www.imaxx.net/~thrytis/glibc/glibc-FAQ.html</A>. Below are some tips for solving problems which are not covered in the FAQ or are covered here in more detail. <P> <H2><A NAME="ss8.1">8.1 Host names do not resolve.</A> </H2> <P> <!-- glibc!problems!names not resolving --> <P>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 <CODE>/etc/nsswitch.conf</CODE>. If host names are not resolving for you when using a glibc 2 application and your <CODE>/etc/resolv.conf</CODE> is configured correctly, check if you have the <CODE>/etc/nsswitch.conf</CODE> file. If you do not have this file, you can create one containing the line: <BLOCKQUOTE><CODE> <PRE> hosts: files dns </PRE> </CODE></BLOCKQUOTE> It will now look for <CODE>/etc/resolv.conf</CODE> to find the nameservers. <P>You should look at the section of the libc info pages describing the nsswitch.conf file for more details. <P> <P> <HR> <A HREF="Glibc2-HOWTO-9.html">Next</A> <A HREF="Glibc2-HOWTO-7.html">Previous</A> <A HREF="Glibc2-HOWTO.html#toc8">Contents</A> </BODY> </HTML>
