If all you want to do is find what is running on the remote machine, you don't need anything more complicated than:

Code:

ssh user@server ps -A

That sounds kind of shady. What are you trying to do this for?

I don't know that there is any way to run a program on a machine without that machine knowing.

Of course there is not. A kernel can't create a process without knowing that that process exist. It's an incongruent statement.

If you really want to run as stealthy as possible, why are you intending to do lots of transformations on the client machine? It's the wrong way.

Instead, pick the needed data, bring it to your server and transform it there locally.

Code:

ssh user@machine << EOF > outfile.txt
ps -A
cat /proc/cpuinfo
#whatever you want to run to collect data
EOF

Then do whatever you want with that data on your server.

Either I am missing your point completely or you are overreacting. We all do administrative tasks everyday that require similar things. This is not illegal activity. In first place you need to login to that machine using ssh with an user name and a key, that alone should be enough to demonstrate you are a legitimate user on that machine (and if you aren't it's your problem, not ours).

This is completely unrelated to an exploit or whatever you imagined and I see nothing that's not legitimate on this thread.

Did you read the OP's post? Here are some key 'shady' sentences:

Quote:

...find all system information of client machine from a server without tyhe knowledge of client machine that a script is running.

aka, without setting off any alarms and without being logged.

Quote:

...i trnsfer the file to client machine run it...

aka, run a program that he doesn't want anyone to know he ran.

If this doesn't sound shady to you, then you're crazy. (IMO)

Yup.

THat's your interpretation. Those words are not his. Anyway, as I already explained: you can't do so without being logged and you can't run anything on a given box without the kernel noticing it. So, that should be clear by now. No need to repeat it again.

Maybe he just want to monitor the usage that their (co) workers are doing of the bussiness resources. This might be a bit big-brotherish, but perfectly legal. As I already said, if he has login access then there's nothing for us to worry about, and if he hasn't there isn't either, since he can't do anything. I don't know what the problem is...

I might be crazy, but not because of this.
