PPPL Unix Cluster
rsh and rlogin Logging into another computer
ssh(1) and slogin(1) are "secure" replacements for rsh(1) and rlogin(1). You may wish to use them because:
The primary documentation is via the manpages: ssh(1), sshd(8), slogin(1), scp(1), ssh-keygen(1), ssh-agent(1), ssh-add(1).
The main ssh web site is http://www.ssh.fi/sshprotocols2/. (Note that the Unix Cluster is currently running version 1.2.x of ssh.)
A nice tutorial on ssh is at http://www.tac.nyc.ny.us/~kim/ssh/. This includes pointers to more information.
There is also https://w3.pppl.gov/~karney/ssh-sem.txt with PPPL specific information.
There are three primarly ways in which a connection to a remote host can be authorized by ssh.
~/.rhosts' (or `
~/.shosts') on the remote host. See rhosts(4)
The first two should be easy to use. The third requires some a little more work to set up, but is more secure and does not require that the host you're connecting from be already known to the remote host.rsh and rlogin Logging into another computer
