Hi,

I noticed in the server via w

it showed me


xxxxx     pts/12   172.21.51.155    17Jul12 38days  0.02s  0.02s -bash
yyyyy     pts/14   :3.0             16:05    7:46m  0.01s  0.01s -bash
wwwwww    pts/15   172.21.49.37     Tue14    2days  0.19s  0.19s -bash
yyyyy     pts/17   :2.0             Thu16   31:06m  0.01s  0.01s -bash


I am quite confused for yyyyy, s/he is not administrator, neither s/he
can access the server directly without ssh, how can s/he shows as  :2.0
and :3:0

Thanks with best regards,
