Network interface selection criteria is not working for a duplicate IP addresses but one is down ------------------------------------------------------------------------------------------------ Key: WFCORE-2626 URL: https://issues.jboss.org/browse/WFCORE-2626 Project: WildFly Core Issue Type: Bug Components: Domain Management Environment: On Fedora 24 KVM instance, I added 2 extra NICs those are recognized as ens9 and ens10. Both have 192.168.1.1 but one is down. {code} # ip address show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 52:54:00:ca:86:e2 brd ff:ff:ff:ff:ff:ff inet 192.168.122.117/24 brd 192.168.122.255 scope global dynamic ens3 valid_lft 3483sec preferred_lft 3483sec inet6 fe80::782d:5d87:243d:917f/64 scope link valid_lft forever preferred_lft forever 3: ens9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 52:54:00:ee:c6:16 brd ff:ff:ff:ff:ff:ff inet 192.168.1.1/24 scope global ens9 valid_lft forever preferred_lft forever 4: ens10: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000 link/ether 52:54:00:52:78:ca brd ff:ff:ff:ff:ff:ff inet 192.168.1.1/24 scope global ens10 valid_lft forever preferred_lft forever {code} Reporter: Osamu Nagano Assignee: Brian Stansberry Fix For: 3.0.0.Beta16 In the standalone.xml, there are {{<up/>}} criterion which is sufficient to identify a unique NIC under the environment described above. {code} <interfaces> <interface name="management"> <up/> <inet-address value="${jboss.bind.address.management:127.0.0.1}"/> </interface> <interface name="public"> <up/> <inet-address value="${jboss.bind.address:127.0.0.1}"/> </interface> </interfaces> {code} But it says "ambiguous".
