I have an issue with password less authentication via ssh ( v2)
I have two servers Server A and Server B, following are the server details
I have copied the public keys across both the servers and pasted them in authorized_keys file. Following are the things i have checked
a] .ssh -- direcotry permission is set to 700 on both boxes
b] authorized_keys file is 640 in terms of permission
The issue is I m able to connect to Server A from Server B as user xyz ( whose keys have been exchanged for paswordless auth) .When I try the same from Server B to Server A I fail and it prompts me for a password.
I think that is the wrong permissions for the dirs, but I am between ssh's. I recall having very specific permissions for both the files and the dirs. Once I get it right using "ssh2 localhost pwd", then I "scp2 -rpd .ssh* remote:.", and everything works there that works here except, ironically enough, localhost and 127.0.0.1, as the local key is changed, but it tells you what line to remove/update.
Finally the issue is now resolved.It was a permissions issue.I noticed later that home directories of the users having issues for some reason were globally writable.I realized it when I initialed a strace. I have changed the permissions to 700 and it works as a charm.
Thank you all for your valuable time and feedback

I generated a public key that we are using for ssh and sftp but I noticed that I am still being asked for a password when I run my script. is there something I need to put in my script?
Our linux guy said he placed keys on both servers. (2 Replies)
My password-free ssh connection has worked in the past but has stopped working and I can't get it going again.
The files in .ssh on both source and target are set to 600:
