Hmmm -- I can't get this to happen here, on an ssh connection where X11 isn't forwarded (e.g., neither afni nor suma will start).
I do notice you are somewhat out-of-date -- for example, your align_epi_anat version is 1.48, and we are now at 1.50. Update your afni binaries and try again. Normally, the command
@update.afni.binaries -d
would do the job, but since you seem to be running a Debian compile of AFNI that we don't supply, you'll either have to update from whatever source you got AFNI, or you'll have to switch to one of our binary collection -- probably linux_openmp_64.tgz
