dsclose commented on CLOUDSTACK-9385:
-------------------------------------
CLOUDSTACK-9035 suggests that the password server should also be running on the
backup router. I will work under that assumption for now.
I'm going to try the code suggested by [~weizhou]] and report back.
> Password Server is not running on RvR

> Key: CLOUDSTACK-9385
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9385
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: ISO, SystemVM
> Affects Versions: 4.6.0, 4.6.1, 4.6.2, 4.7.0, 4.7.1, 4.8.0
> Reporter: dsclose
>
> NB: I have not tested this on VPC routers.
> The cloud-passwd-srvr service fails on redundant virtual routers. This
> appears to only concern redundant virtual routers. Standalone routers launch
> the password server successfully, as per this bash session:
> {code:title=Standalone Router}
> root@r-3775-VM:~# ps aux | grep passwd | grep -v grep
> root 2257 0.0 0.5 9244 1328 ? S 14:27 0:00 /bin/bash
> /opt/cloud/bin/passwd_server_ip 10.1.1.1 dummy
> root 2259 0.0 3.2 37276 8128 ? S 14:27 0:00 python
> /opt/cloud/bin/passwd_server_ip.py 10.1.1.1
> root@r-3775-VM:~# netstat -tnlp | grep 2259
> tcp 0 0 10.1.1.1:8080 0.0.0.0:* LISTEN
> 2259/python
> {code}
> However, redundant virtual routers do not exhibit this behaviour. Instead,
> the password server process is running without an IP argument. No matching
> process is bound to any ports:
> {code:title=Master Redundant Virtual Router}
> root@r-3776-VM:~# ps aux | grep passwd | grep -v grep
> root 5152 0.0 0.2 17684 1516 ? S 14:38 0:00 /bin/bash
> /opt/cloud/bin/passwd_server_ip None dummy
> root@r-3776-VM:~# netstat -ntlp | grep 5152
> root@r-3776-VM:~#
> {code}

> No process is bound to the password server port. Consequently, attempts to
> request a password from the password server get rejected.
> Manually restarting the cloud-passwd-srvr resolves this issue immediately:
