VMWare Horizon View Mac client USB Smartcard passthrough

I came across a need to pass through a USB smartcard device to a VM using the VMware Horizon View client for Mac OS. My smart card reader would not show up in the list of devices to redirect to the VM. After doing some research I came across this document which outlines the commands I needed to run:

sudo defaults write com.vmware.viewusb IncludeFamily smart-card
sudo defaults write com.vmware.viewusb AllowSmartcard Enable

You can verify which settings have been applied with the following command:

sudo defaults read com.vmware.viewusb

Success! The client now sees my smartcard reader as an option to pass through to a VM guest.

 

Fix vmware-view RDP issues in Linux

I’ve been using vmware view as a means to remote into my computers at work for some time now. An update to the linux client appears to have broken my ability to remote into work machines over the RDP protocol. This issue affects multiple distros.

The symptom is the fact that after you log into vmware-view and double click on a computer you wish to connect to over the RDP protocol, the screen flashes for a second and then takes you right back to where you started – no error message. Frustrating.

If you launch vmware-view in a console you get a little more insight into what’s going on:

RDP Client(10222): WARNING: Unknown -r argument
2017-02-26 14:06:53.817-07:00: vmware-view 7858| RDP Client(10222): 
2017-02-26 14:06:53.817-07:00: vmware-view 7858| RDP Client(10222): Possible arguments are: comport, disk, lptport, printer, sound, clipboard, scard

After much frustration I was able to combine documentation from vmware and freerdp in order to finally get the right combination of arguments to get things working again. I read that freerdp works better than rdesktop with this version, so I tried launching vmware-view with this option:

vmware-view --rdpclient="xfreerdp"

Progress – at least now the error message was different.

RDP Client(20799): [14:04:04:097] [20799:20803] [ERROR][com.freerdp.crypto] - certificate not trusted, aborting.

After more investigation the culprit turned out to be crypto negotiation. Since I’m already connected to the truste work VMware server, I don’t really care about certificate validation. This is what finally got me up and running. The key components are the rdpclient and the /cert-ignore options.

vmware-view --rdpclient="xfreerdp" --xfreerdpOptions="-wallpaper /sound:sys:alsa /cert-ignore"

You can include these options in your ~/.vmware/view-preferences config file so you don’t have to manually add all those switches:

echo 'view.rdpClient = "xfreerdp"
view.xfreerdpOptions = "-wallpaper /sound:sys:alsa /cert-ignore"' >> ~/.vmware/view-preferences

Finally RDP via vmware-view is working in Linux again.
