Package: libc6
Version: 2.7-18
Severity: serious
Problem is about host name resolving.
-> cat /etc/host.conf
order hosts, bind
-> grep host /etc/nsswitch.conf
hosts: files [SUCCESS=return NOTFOUND=continue UNAVAIL=continue
TRYAGAIN=continue] dns
So if i try a host lookup with a name which is defined in my local
/etc/hosts such as ...
-> grep printer /etc/hosts
192.168.2.3 srvprinter
... then, when lanching ...
-> host srvprinter
srvprinter has address 192.168.2.3
and this is a good answer (!!), but if a make a tcpdump on port 53, i see a
request on the dns server, and this behavior is NOT conform to the order as
defined in either /etc/host.conf or /etc/nsswitch.conf
Furthermore, when launching down my Ethernet interface, (my dns server is no
more available), then i confirm alway this behavior.
In this case, when no network is available, then the same command responds
with a timeout, this behavior is BAD because libc6 must ALWAYS make access
to local ressource (because order...) before launching network access.
