----------------------------------------
Summary: Order of nics in non-VPC router changed resulting in
services to fail
Key: CLOUDSTACK-8814
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8814
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: SystemVM
Affects Versions: 4.6.0
Reporter: Remi Bergsma
Priority: Critical
Fix For: 4.6.0
When testing a non-vpc setup, CloudStack was not able to ssh to 169.254.x.y
because it was not listening on this ip:
Isolated network, single router doesn't listen on link_local:3922
tcp 0 0 192.168.23.25:3922 0.0.0.0:* LISTEN
0 6828 3487/sshd
Redundant isolated router:
tcp 0 0 10.20.1.10:3922 0.0.0.0:* LISTEN
0 6434 3068/sshd
The reason for this, is that the naming of the interfaces now seems to be the
same (same order) as on VPC routers. This used to be different.
cloud-early-config uses hard-coded eth devices that seem not to have reflected
to these changes.
setup_vpcrouter() {
...
setup_sshd $ETH0_IP "eth0"
...
==> That works!
setup_router() {
..
setup_sshd $ETH1_IP "eth1"
==> That goes wrong now.
If we keep this new order, all nics need to be checked. Apache settings,
keepalived etc etc
Here you see the difference:
