Description Paulo Matos 2003-03-07 12:58:13 EST
Description of problem:

It seems that the package glibc-2.2.93-5.i386.rpm shipped with redhat-8.0,
has no ipv6 support.

Looking at strace result on lines 121-131 it simply tries to do a ipv4
query to the default nameserver (resolv.conf has only an ipv6 only server).


Version-Release number of selected component (if applicable):
2.2.93-5 

How reproducible:
Always

Steps to Reproduce:
1.ping6 www.kame.net (e.g)
2.
3.
    
Actual results:


Expected results:

There is no way to compile glibc without IPv6 so this is definitely not the reason.

From your strace output it seems there is a problem with the DNS server. 
Reading the results produces problems.

Anyway, I assume ping6 uses getaddrinfo.  getaddrinfo has been changed
significantly for RHL9.  Please try RHL9 and let us know.

Red Hat Linux and Red Hat Powertools are currently no longer supported by Red
Hat, Inc. In an effort to clean up bugzilla, we are closing all bugs in MODIFIED
state for these products.

However, we do want to make sure that nothing important slips through the
cracks. If, in fact, these issues are not resolved in a current Fedora Core
Release (such as Fedora Core 5), please open a new issues stating so. Thanks.
