Hi,

I am trying to ssh between two differnt versions on solaris boxes.
The src box has the SSH Secure Shell 3.1.0 on sparc-sun-solaris2.6 and destination has SSH Version Sun_SSH_1.0, protocol versions 1.5/2.0.

I am not trying for passwordless connection. I just want to get it working with a password before i proceed with passwordless.

I get the below error
warning: Authentication failed.
Disconnected; key exchange or algorithm negotiation failed (Key exchange failed.).

Can anyone suggest what needs to be done to get this working

Thanks in advance

try manually by setting

-o "Compression no"

, but basically it means

.
You can also search in server config for :

  • try addind a comma, and then none; like this :
AnyCipher, none

and see if it works. If not - time for upgrade.

Hi,

I got ssh working through password. Now, started trying for passwordless connection using key authentication. But still get the below error:

Can someone help me or suggest any alternatives

Thanks in advance

Uh.. depends... are these logs from client or the server ones ? Take a look at both of them; also make sure that permissions are OK, i.e. user should be able to read his own ssh files.
