I have the same issue on precise. I just apt-get installed zookeeper, and I have
tcp6 0 0 :::2181 :::* LISTEN 3425/java but no corresponding tcp listening socket. I do not have any sort of explicit IPv6 configuration, just the default networking setup from precise, running DHCP on wifi: $ ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:23:32:cb:1e:60 brd ff:ff:ff:ff:ff:ff 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:23:6c:87:2c:2d brd ff:ff:ff:ff:ff:ff inet 192.168.1.105/24 brd 192.168.1.255 scope global eth1 inet6 fe80::223:6cff:fe87:2c2d/64 scope link valid_lft forever preferred_lft forever 4: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN link/ether fe:72:b9:dd:78:47 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 ** Changed in: zookeeper (Ubuntu) Status: Incomplete => Confirmed ** Changed in: zookeeper (Ubuntu) Importance: Medium => High ** Changed in: zookeeper (Ubuntu) Milestone: None => ubuntu-12.04-beta-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/888643 Title: Zookeeper listen only to IPv6 interface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zookeeper/+bug/888643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
