SSH issues 3

[chieftan]

Any one got any ideas why SSH should work in one direction but not the other?

2 Linux boxes....... I can run SSH from one linux box to the other with no problems at all (on a cluster) but when I try and do the same thing the other way around it fails.

This causes issues for our replication services.

Can anyone help please?

does sshd is started ?

Actually, I got that slightly wrong.....thanks for the response 'gloups'.

What I meant to say was that in one direction the connection is immediate, so replication could take place, but in the other direction it asks for a password.... this is why replication will fail.

Any ideas?

Make sure that the public key is exchanged in both directions.

if you need a howto on ssh (open/commercial), here is a good resource:

just run

[code}
ssh-keygen -t rsa
[/code]

follow instructions and leave password blank if you do not want to type a password at each login.
Now, let's assume that you will name your key "myKey", linux will generate a file called myKey (private key) and a file called myKey.pub (public key)

copy the public key to the remote host and cat it into the file ~/.ssh/authorized_keys

cat myKey.pub >> /home/your_user/.ssh/authorized_keys

if root obviously the home is /root
ON the client machine start ssh-agent

ssh-agent /bin/bash

then import the private key

ssh-add myKey

Okay, I have completed the above and a very strange problem is occuring:-

If I log on as root on one box I can ssh one direction but as a normal user I cant.

When I log on as root on the second box, I cant ssh but if I log on as a normal user I can.....

How weird is that.......

I have checked all the files and permissions and passwords and it still does not work.

Still, it asks for the password when trying with the opposite of what works.

it depends on wjere you have saved the keys.

Have you checked that each user you want to connect has its set of public/private in both machines?
