Re: connection with RSA and DSA

[mansour77]

Hello every body, and thanks alot, the issue has been fixed.
Just to let every body know. It was a prolem with the home directory 
permission.
# tail /var/log/secure
# Oct 11 19:49:30 neptune sshd[6530]: Authentication refused: bad 
ownership or modes for directory /home/mansour
# cd /home
# ll
drwxrw-r--  42 mansour mansour 4096 Oct 11 19:04 mansour
# chmod go-rw mansour
And things went great. Thank you every body. Now I can automate the 
deployment of what ever I need on the remote system.

Hi [EMAIL PROTECTED],

Why do you create both RSA and DSA keys?

I would suggest trying the same steps with _only_ one type, say
"ssh-keygen -t dsa" on both servers, and cat over into authorized_keys.

Basically, my understanding of your log is:

1. Client is trying to authenticate with rsa key, but somehow it's not
there (on local box).

2. Client send dsa key, but remote box cannot recognize/ understand (it
expects rsa according to entry in it's authorized_keys) so the
last option is used as to prompt for a password.


I might be wrong, please correct me.

With a subject: connection with RSA and DSA

 

hello Admins:

I am having an issue connecting to a remote PC in the same lan usign
ssh with RSA or DSA.
the connection I am trying to establish is between two servers: ploto 
and neptune.
ploto is running Fedora 4 and neptune is Fedora 3.  I generated the
RSA and the DSA keys on both of them,
and copied the key the correct way. ( keys generated on ploto are
cat id_dsa.pub >>  ./ssh/authorized_keys on neptune).
The same way done on neptune and copied to ploto. Now theoretically
both systems are opened for each others.
That's not the case with me, I can connect from "ploto to ploto" with
no any problems. and I can connect "from neptune to ploto".
However I can not connect to neptune at all. I copied the
configuration files from ploto to neptune, and stil the same thing. I
am always prometed with the password. Any Help will be highly
appreciated. Here is the out put I have:
