VMware EUC Access Point appliance – Name resolution not working after deployment

As part of a project, I had to deploy a VMware EUC Access Point appliance. Nothing fancy, because the awesome VMware Access Point Deployment Utility makes it easy to deploy.

Unfortunately, the deployed Access Point appliance was not working as expected. When I tried to access my Horizon View infrastructure behind the Access Point appliance, I got a HTTP 504 error. The REST API interface was working. I was able to exclude invalid certificates, routing, or firewall policies. I re-deployed the appliance using the the IP address of the connection server, instead of the FQDN. And this worked… I checked the name resolution with nslookup and the name resolution failed. So that was probably the problem.

One per line

To make a long story short: The DNS server, I entered in the VMware Access Point Deployment Utility, were added in a single line to the /etc/resolv.conf

This is wrong, even if the VMware Access Point Deployment Utility claims something different.

There must be a single “nameserver” entry for each DNS server.

You can easily change this after the deployment. Add only one DNS server during the deployment, and then add the second DNS server after the deployment.

I would like to highlight, that Chris Halstead mentioned this behaviour a year ago in his blog post “VMware Access Point Deployment Utility“. Chris is the author of the Deployment Utility.
