We already have a wildcard certificate for *.mycompany.com. Our network has hosts that are only reachable internally. All of them belong to the internal.mycompany.com subdomain. There is a private server with the host name server.internal.mycompany.com on which I deployed our wildcard certificate.

When I visit the web server I get a host name mismatch error. Do I really have to get another wildcard certificate for *.internal.mycompany.com or is there another (free!?) way to use our wildcard certificate for all of our subdomains and its subdomains without getting an error in the browser?

We have dozens of Ubuntu nodes where I have to resize the hard disk drive to different sizes. Currently I’m doing all of the following steps manually:

1. Increase the size of each node’s virtual hard disk in VMware vCenter.
2. Change the configuration of the DVD drive, mount a GParted ISO, boot from BIOS, and change the boot order.
3. Boot into GParted, manually increase /dev/sda2 and /dev/sda5.
4. Stop the VM, disable the DVD drive, and start the VM.
5. Use lvextend -r /dev/ubuntu/root /dev/sda5 to extend the LVM and resize the partition to its maximum possible size.
6. Optional: Check with df -h if everything’s OK.

I would love to automate this process, in a best case to provide a list of node names and corresponding sizes and let the tool do its job. In the case where there is no automated solution available I would love to hear about micro-optimizing every of these steps to make my tedious job easier.

We’re already automatically provisioning our nodes with Chef, and a VM template with a hard disk size of 16 GB.

Any smart ideas?
