Bug 588716 – sys-libs/glibc: nscd causes mdns *.local lookups to fail

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Reuben Martin 2016-07-12 22:28:07 UTC]

mdns lookup is working:

$ avahi-resolve-host-name HPStream1-Linux.local
HPStream1-Linux.local   172.16.4.6	


it seems to be propagating to glib (though it takes a little long to lookup):

$ getent hosts HPStream1-Linux.local
172.16.4.6      HPStream1-Linux.local	


I can ping it using a .local address:

$ ping HPStream1-Linux.local
PING HPStream1-Linux.local (172.16.4.6) 56(84) bytes of data.
64 bytes from hpstream1-linux.office.kc.com (172.16.4.6): icmp_seq=1 ttl=64 time=0.136 ms
64 bytes from hpstream1-linux.office.kc.com (172.16.4.6): icmp_seq=2 ttl=64 time=0.142 ms
^C

2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 0.136/0.139/0.142/0.003 ms	


But ssh doesn't want to play nice:

ssh HPStream1-Linux.local
ssh: Could not resolve hostname hpstream1-linux.local: Name or service not known

After stopping nscd, ssh works.

From nsswitch.conf:

hosts: files mdns4_minimal [NOTFOUND=return] resolve mdns mymachines wins myhostname



Reproducible: Always

do you have any known working versions ?

I do not, but then again I've ripped nscd out of all my machines since then and rely on the cache built into systemd's resolver.

OK not much we can do here... Feel free to reopen when you can reproduce the problem.
