Re: SSH from windows to linux using public key authentication



Check your permissions on $HOME/.ssh. Must be 700 to work correctly. Bad permissions fails silently even with debug set. Check /var/log/secure and, if I'm right, you should see a line like:

Authentication refused: bad ownership or modes for directory etc...

Hello Friends,
I am having problem using SCP to copy files from windows to linux using
public key authentication.
I have two linux computer (RHEL AS 3) named as drolinux and prolinux.
From windows to linux(drolinux) using public key authentication works just
fine. logs attached for scp -v
I have copied exact same public key to my Prolinux and it's not working.
I tried copying authorized_keys from drolinux to prolinux and still I have
no success to do ssh from windows to prolinux using public key
authentication.
Any help is appreciated.
note: I do not have access to logs on my both linux server.

scp -v From windows to linux (hostname: drolinux) working fine.
