Hi, I am a engineer at NASA's Ames Research Center's Advanced Supercomputing Dvision located in Silicon Valley, CA. I am currently researching for proxies for ssh and scp and am curious about Delegate and its potential. I am hoping that I can get a better understanding by asking some questions. My basic situation is that I have a group of special computers that remote users want to log into, of which I don't want to be exposed to the outside world. So I am looking for a proxy/firewall that will act as the filter of all these user login and file transfers. We would also want to be able to enable secure ftp, scp from our target servers to the client and back also in this setup. The main idea is that we wanted users to feel like they were getting transparent ssh/scp/sftp access to our network while actually having a trusted box in the middle through which all access requests were mediated. Do you feel Delegate is an appropriate solution? What issues/concerns do you have in mind? You have specified that it supports all TCP protocols, which includes ssh, correct? Would users have to install Delegate as a client side program? Are there other requirements on the user side? I truly appreciate all your help and time. Thanks in advance.
