Dear All,

General instructions are at https://www.sdcc.bnl.gov/information/services/how-use-nx-sdcc

For us specifically, choose nxcampus01 to start your session

Personally, I like to use a customized session, running the command gnome-terminal in a floating window, feels almost like a local shell instead of a clunky virtual desktop. 

nxcampus doesn't properly mount ~, just like cssh, so .ssh is not populated, however, ssh-agent forwarding works on cssh but not on nxcampus, "SSH connections are only available in the Enterprise products"

Create .ssh/id_rsa and .ssh/id_rsa.pub by hand, and fill them with the correct values. 
From there, just remember to use the minus X flag
ssh emcalgw.phy.bnl.gov
ssh -X eic@lappd
root
new TCanvas

Sanghwa, Alexander, could you try and see if some of the plots that overloaded X11 during the last test beam work fast enough this way?

Thanks,
Kolja
