Rereading the original post, I note that KenLee only said 'cmd' was started once in the OpenSSH session. I also assumed he invoked 'ssh' from a console, which may make a difference if the answer to the above question is "no". But that assumption is unsubstantiated by the available information. ;-) -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
