Package: libc6
Version: 2.3.2.ds1-20
Severity: normal


I first discovered this behaviour while configuring nss to use
libnss_lwres.  Having added to nsswitch.conf the line

hosts: files lwres [NOTFOUND=return] dns

I found that many binaries (ssh, apt-get, telnet although not ping)
would fail to do dns lookups when lwresd was not running.  They were
treating the unavailability of lwres as a NOTFOUND result and proceding
no further.  Changing the line to

hosts: files lwres dns

Made the probem go away but is obviously not the best solution.

This is not a bug in libnss_lwres: the behaviour persists if
alternatives are used or if a non-existent name switch module is used
(i.e. "hosts: files bogus [NOTFOUND=return] dns" triggers this bug but
"hosts: files bogus dns" does not).

If the NPTL libc libraries are not available (I tested this by moving
/lib/tls to /lib/tls.bak), the bug does not appear and nsswitch behaves
as it should.

This bug may be linked to #222130 but I can't be sure atm.
