I am getting the same error with the TCL API. I'd like to also note that I am using the 64-bit version of the client on fedora linux:

% stc::connect 10.0.1.21

18:26:02.801 ERROR - in connect: unable to create unknown command "connecttochassisCommand"

RuntimeError in connect: unable to create unknown command "connecttochassisCommand"

Hey! You should use the Spirent_TestCenter_Auto_Linux_4.50.gz with 32 bit only. And with limitation of python 2.7. That's the way it can work. Spirent high-tech :\

The 64bit linux client is for spirent test-lab...

*put attention, i'm working with python, you're looking to work with tcl, but probably the same.. use 32bit machine

Ok, the 32-bit version of TCL seems to work. Thanks for the help.

Have you called the package "package require SpirentTestCenter" before calling stc::connect?

Also you need client to be 32 bit version along with 32 bit tcl or python to successfully run the STC API

Yes, I set up all of the TCL libraries as specified in the API/Tcl/readme.txt and did the package require. So, I am using the "Spirent_TestCenter_Auto_Linux64Client_4.50.tar" 64-bit client downloaded off the Spirent support web site. Does this version not work?
