Re: [Condor-users] MATLAB licenses

["Junaid N. Sahibzada" <sjunaidn@xxxxxxxxx>]

i would also love to know the soloution for this.
  
  we have a network edition matlab and the liscense allows only two people to use it at a time.
  
  how can i resolve the liscence issues if i want to use matlab under condor?
  
  for using matlab i have to edit my .ssh file and add keys to the server where matlab is installed.
