Shell Programming and Scripting

Hi All,

i have problem with ssh

i have three server(linux box) like below

server A
server B
server C

i did ssh(Private key & Public key) for passwordls ..

i did for server A to Server B connection without any issue

now i am able to connect server A to server B without password

but when i am trying to create ssh keys from server C to server A i am not able to connect without passowrd(eventhough it seems everything fine)..

i created keys using below steps (server A to server B)

ssh-keygen -t rsa
ssh b@B mkdir -p .ssh
cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
ssh b@B hostname

My question here is ...

is there anything else that i need to check for connectivity problem..
because everything seems fine.(whatever i did the same i did for server c also )

can anyone suggestme plz..

Thanks
Sha

Do you have the same SSH version on all three?

Thanks for the quick replay

I belive yes..

also i am afraid if you could explain me how to check the version for ssh..

one thing here is ..i am able to connect server C from server A (ssh) without password.- i tried to creat key in reverse manner( server A to server C )

only from server c to server A i could not ...


Thanks

Hi,

I just found the ssh version for server C and server A

server C version is

OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003

and server A version is

OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f

now can anyone tell me..
i want to connect server A from server C using ssh without password.

do i need to use some different command for key generation(public and private key)

or any suggestion for the below steps

ssh-keygen -t rsa
ssh b@B mkdir -p .ssh
cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
ssh b@B hostname


Suggestion would be much appreciate..

Thanks
