Issue installing latest VAN; possible postgreSQL error?

brandonh — Tue, 14 Apr 2015 17:52:37 GMT

I'm trying to run HP VAN on Ubuntu 12.04, using VMware Fusion and giving the VM plenty of resources (8GB RAM, 4 cores). The install appears to run to completion but I can't get to the GUI; the log shows some PSQL exceptions that might be the issue.

All browsers fail to connect, reporting:

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

The port is not listening:

brandonh@precise:~$ netstat -nl | grep 8843

… and the log shows PostgreSQL errors, which might be the root cause of the breakage:

sudo cat /var/log/sdn/virgo/logs/log.log | grep -i except

[2015-04-14 10:31:22.320] INFO System Bundle Shutdown System.out [EL Info]: UnitOfWork(1494023401)--Communication failure detected when attempting to perform read query outside of a transaction. Attempting to retry query. Error was: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.DatabaseException

Full details of the commands I ran are at the bottom. Anyone have any ideas? Thanks in advance.

^{I tried out version 2.4.3 as well, and saw the same error.}

^{If you'd like to try it out, I've posted a script here as a gist:}

Hi Brandon

The Certifacte signing requirements for a large portion of browsers has recentaly changed, and because of this the orignal self signed version for the SDN Controller conflicts with these browsers minimum requirements. Here is the procedure for manually generating a new self signed certificate.

Bold Italic text is commands

Bold is Important notes

I have indented sample output

The following needs to be done as root hence( I am assuming the account your are using does have sudo premissions for root)

sudo service sdnc stop

Then the following needs to be done as the user which the sdn controller controller runs as(The user is the user sdn by default), since the truststore and keystore must be readable by that user.

Hint to become the user sdn us the following “sudo su – sdn”.

cd /opt/sdn/admin

ls -l *store*

sdn@ubuntu:~/admin$ ls -l *store*

-rw-r----- 1 sdn sdn 1319 Mar 20 14:53 keystore

-rw-r----- 1 sdn sdn 913 Mar 20 14:53 truststore

Note the permissions and ownership of the files

Here we generate a self-signed certificate with a validity period of 1780 days, after moving the old keystore and truststore away.

Note you need to use the password “skyline” below unless you have changed it. I have added it in for clarity in the commands below but it will not show when it is typed.

Leave the password for the key the same as the keystore password.

mv keystore keystore.orig

mv truststore truststore.orig

keytool -genkey -alias serverKey -keyalg rsa -keysize 2048 -keystore keystore -validity 1780

sdn@ubuntu:~/admin$ keytool -genkey -alias serverKey -keyalg rsa -keysize 2048 -keystore keystore

Enter keystore password: skyline
