			==Accessing DICOM Remotely==
			If you want to access the DICOM server from off-campus, you will need to either use a Mednet-specific VPN or log into Hoffman2 first, then ssh into DICOM. Trying to ssh into DICOM directly from a general UCLA VPN (or no VPN) will result in your login request hanging until it times out.
