When i do rsh i give it two commands:
rsh <host> setenv $myPath; $mySecCommand >> <filename>
that works perfect when i set the .rhosts file on the target host. But when i dont set the .rhosts file it gives me an error message, but it seems like it can do the setenv anyway and i get what i want, without the correct permissions? Is this a "hole" in the sequrity. Because doing it this way i actually dont need the .rhosts file. I get what i want even if it complains.
The command posted runs two separate commands on the local computer, one of which is a "rsh". The semi-colon is actioned locally, as is the ">> <filename>".
After the semi-colon is executed locally.
The "rsh" is itself a local command but the parameters (in this case up to the semi-colon) are executed on the remote machine as shell commands.
If we escape the semi-colon the second command gets executed on the remote computer too. The log file still gets created on the local computer.
To me personally this is all academic. For anything beyond the simplest command line I would put the commands into a script on the remote machine and execute the script with:
Code:
rsh <host> -n "scriptname <parameter>"
The script itself would contain a shebang line and anything needed to set up a suitable environment to run the process.
A quick way to check which computer a command is executed on:
rsh remote_machine -n "uname -n";uname -n
rsh remote_machine -n "uname -n"\;"uname -n"
