For some works, i want to transfer files with scp for sun stations and pscp (member of the putty suite) for nt servers to a dedicated station. This tranfer should be done without any uman intervention. the accounts are only allowed to do scp with shell-wrapper like the one found on snailbook (http://www.snailbook.com/faq/restricted-scp.auto.html). no problems encountered when i play only with openssh implementations BUT with pscp There is a problem. I've got this error : environment variable SSH_ORIGINAL_COMMAND not set I've modified the perl script to print all env variables : the sshd server does not create this env variable ! (I don't known how exactly the server creates this variable with datas taken from clients) My goal is to be able to transfer files (filenames are not fixed) from nt servers to a sun station . Anybody got a good idea (or solution) to help me to solve this. thanx
