You only need to modify authorized_keys in both places if you want the symmetric relationship that either machine can log into the other. Correct. I mentioned that I did not have to alter the authorized_keys file on my work PC in response to the OP's statement: I know how to solve the issue, i.e. by cross appending the authorized_keys files, in order that each machine knows itself. But there must be a simpler way. I have no idea why you would need to do something like that. I have never had to cross-append anything in order to make this work. I just wanted to clarify for the OP that the keys only need to be shared in one direction to do this. He seems to indicate that the passwordless login works just fine unless he tries to run a command through the ssh command line. I don't know why that would make a difference. Big difference for me. As I said in my original post, certain computational parallelized codes (from major supercomputer centers, latest versions) do not work unless the two machines talking to one another also know themselves. Usually, the two machines are my desktop (let say deb32) and my parallel computer (let say deb64) talking to one another via a router.The only way I found (perhaps suggested by the author of the code, I don't remember) to login passwordless (my arrangement is also passfraseless) to the parallel computer - and vice versa - while requesting the date, is to take the deb32 keys from deb64 and append them to those of deb32 itself, and vice versa. I admit that most codes do not care about that, but it happens that I am using at this very moment a code that has such idiosyncrasy. When I said there must be a simpler way, I meant to make that appending intrinsic in the configuration of ssh. Otherwise, I have to stay to ssh if I want (as I need) also to access supercomputers. I am surprised that others are able to login while running a command by simply sending one-way the keys. As I am no system expert, I assume that I am not setting up correctly ssh. regards francesco Francesco, If I understand you correctly, you are trying to ssh from your PC running 32-bit Lenny to a node in a parallel computing cluster running 64-bit Lenny. Is this correct? I'm not sure why a simple one-way shared key would not work if you are trying to run a command on the parallel computer from your PC. You shouldn't need two-way authentication unless the parallel computer needs to run something on your machine using the same tunnel. But I might be misunderstanding how you have things set up. - Dave P.S.

Re: ssh
Is any 'send file' command to make so that two machines (an amd64 multisocket and a simple i386, both lenny) talk scp with one another through a router (attached to adsl) fully without asking the password? With 'fully' I mean that command: ssh target_machine_name date gives the date without asking a password. The mere sending id_rsa.pub to create the authorized_keys file only works (without asking the password) for command: ssh target_machine_name but if 'date' is also requested, the password is needed (at least in my hands). I know how to solve the issue, i.e. by cross appending the authorized_keys files, in order that each machine knows itself. But there must be a simpler way. That's odd. I am able to get commands to work over SSH without a password. I copied the contents of ~/.ssh/id_rsa.pub on my work computer into ~/.ssh/authorized_keys on my home computer.
