Bug 159341 – sys-auth/nss-mdns incorrect avahi-daemon socket path

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gioele Barabucci 2006-12-28 21:29:07 UTC]

getent does not return IPv6 addresses served by Avahi.

for example, ping6 will return unknown host.

| $ ping6 woodstock.local
| unknown host
|
| $ ping woodstock.local
| PING woodstock.local (10.1.1.2) 56(84) bytes of data.
| 64 bytes from 10.1.1.2: icmp_seq=1 ttl=64 time=0.076 ms


getent should prefer IPv6 addresses but does not

| $ getent hosts woodstock.local
| 10.1.1.2        woodstock.local

avahi-browse get it right:

| $ avahi-browse -a -r
| +  lan IPv6 woodstock [00:0d:93:c2:1c:6a]  Workstation   local
| +  lan IPv4 woodstock [00:0d:93:c2:1c:6a]  Workstation   local
| =  lan IPv6 woodstock [00:0d:93:c2:1c:6a]  Workstation   local
|    hostname = [woodstock.local]
|    address = [fe80::20d:93ff:fec2:1c6a]
|    port = [9]
|    txt = ["org.freedesktop.Avahi.cookie=284036072"]
| =  lan IPv4 woodstock [00:0d:93:c2:1c:6a]  Workstation   local
|    hostname = [woodstock.local]
|    address = [10.1.1.2]
|    port = [9]
|    txt = ["org.freedesktop.Avahi.cookie=284036072"]

in /etc/avahi/avahi-daemon.conf I have
| use-ipv6=yes

in /etc/nssswitch.conf I have
| hosts:       files mdns_minimal [NOTFOUND=return] dns

my interface is configured as
| $ /sbin/ip addr show dev lan
| 2: lan: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc htb qlen 1000
|     link/ether 00:0d:93:c2:1c:6a brd ff:ff:ff:ff:ff:ff
|     inet 10.1.1.2/8 brd 10.255.255.255 scope global lan
|     inet6 fe80::20d:93ff:fec2:1c6a/64 scope link
|        valid_lft forever preferred_lft forever

Configuration (~ppc):
* Avahi 0.6.15
* nss-mdns 0.8
* glibc 2.4-r4

strace log of "ping6 woodstock.local"

[Comment 2 Gioele Barabucci 2006-12-28 21:56:34 UTC]

tedp on #avahi spotted the problem: nss-mdns tries to connect to /var/lib/run/avahi-daemon/socket, a file that does not exist. The socket created by avahi-daemon is at /var/run/avahi-daemon/socket (no /lib after /var).

nss-mdns should be patched to use the correct path.

Thanks for the info.  Please try out -r1, which has a patch.
