modelsim_ae floating license

I have several ModelSim_AE floating licenses. With these licenses, VSIM stars but then failed on ELAB with the following error message:

# Top level modules:# test# End time: 09:56:12 on Jan 20,2015, Elapsed time: 0:00:00# Errors: 0, Warnings: 0# work.test# [exec] elab# vsim # Start time: 09:56:12 on Jan 20,2015# ** Error: Failure to obtain a Verilog simulation license. Unable to checkout any of these license features: alteramtivsim or alteramtivlog.# Error loading design# Error: Error loading design# Pausing macro execution# MACRO ./scripts/test_ready_1_always.tcl PAUSED at line 29

The error message is similar to this one

I run ModelSim on Ubuntu14.04. Does it imply that I need a "Windows Terminal Server remote feature"?

Is it possible to use ModelSim_AE under Linux with a floating license?
