sorry, yes I did mean ssh. <br />

I fixed it. Apparently, in all the times machine A was prompting me for a password I never actually tried to enter one. When I tried following your instructions to scp none of my password attempts worked. It turns out that I never set a password on that account. When I did so, my ssh worked just fine!

<div class="content wysiwyg-content">
I have 2 linux computers. I am trying to rsh from one to the other w/o passwords. I've done this successfully before, but I can't figure out what's wrong this time. On computer A, logged in as user ohprs', I ran ssh-keygen which created ~/.ssh/id_rsa.pub. Permisions:<br />
<br />
ls -l .ssh/id_rsa.pub<br />
-rw-r--r-- 1 ohprs ohprs 394 Apr &nbsp;4 20:37 .ssh/id_rsa.pub<br />
<br />
I copied the contents of that id_rsa.pub file. Then, on computer B, I logged in as user 'ohprs' and pasted the aforementioned copy to the file ~/.ssh/authorized_keys. Permissions:<br />
<br />
ls -l .ssh/authorized_keys<br />
-rw-r--r-- 1 ohprs ohprs 394 2012-04-04 20:39 .ssh/authorized_keys<br />
<br />
I thought this would be sufficient to ssh w/o supplying a password, but it still prompts me for a password when trying to ssh from machine A to machine B.

cannot rsh linux using public key

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
