[GRASS-dev] m.nviz.image - Bad server connection

[epi]

Hi,

i’m tring to generate a 3d image with m.nviz.image, the following command works fine form a ’standard’ GRASS session in text mode on my laptop
but if try to run the same command on a sever while i’m connected via SSH i got the error : Bad server connection

Have you any clue on how to fix this ?
is there any environment var that needs to be exported in order to have m.nviz.image running during an SSH session ?

GRASS 7.0.svn (nc_spm_08_grass7):~ > m.nviz.image \ 
elevation_map=elevation \ 
output=elevation_3d \ 
perspective=15 \ 
height=2000 \ 
color_map=elevation \ 
resolution_fine=1 \ 
resolution_coarse=1 \ 
format=tif


ERROR: Bad server connection
GRASS 7.0.svn (nc_spm_08_grass7):~ > 

Thanks for you help!

Massimo.
