The Barracuda VPN Client does not work properly on macOS Mojave: after connecting the VPN, the UI crashes and restarting it immediately makes it crash again. The VPN tunnel itself does work, but other than manually killing the process (kill -9), it is not possible to terminate the tunnel (other than rebooting of course).
An updated version of the client, Barracuda VPN Client 220.127.116.11 for macOS is available which resolves these issues.

You can easily update your vCenter Server Appliance (VCSA) offline by downloading a product patch ISO and via the CLI.
Download the latest patch from VMware Patch Download Center. Select VC from the Search by Product drop-down menu, then select the correct version (i.e. 6.0 or 6.5). Download the patch ISO and attach it to the VCSA.
Log in to the shell (using SSH or VMRC) and initiate the update:
software-packages stage --iso --acceptEulas
software-packages list --staged
software-packages install --staged
After the update has finished, you will have to reboot the VCSA.
Similar as on FreeBSD and Linux, you can add/remove static network routes through the command line with the route command. The syntax somewhat differs from Linux, though.
To add a route (e.g. subnet 192.168.3.0/24 to gateway 192.168.1.254):
sudo route -n add -net 192.168.3.0/24 192.168.1.254
To remove a route:
sudo route -n delete -net 192.168.3.0/24
To show the current route table, you can use netstat:
Cisco's SF/SG 300/500 series managed switches have CLI access via Telnet and SSH but this is turned off by default, leaving only the web interface to manage the switch. You can enable Telnet and/or SSH via the web interface, enabling management via CLI.
