Hi everyone, we migrated sql jobs and ssis packages from old to new server.
However on the new server, we cannot connect using cozyroc SSH connection manager.

These are the cozyroc ssis+ versions on the 2 servers:
old server: cozyroc ssis+ 1.5.101.0
new server: cozyroc ssis+ 1.6.101.0

We have 2 ssis packages encountering 2 errors:

package 1
-----
SshSession 3.0.4696.0.
Server is 'SSH-2.0-OpenSSH_7.4'
SSH: Sending packet SSH_MSG_KEX_30 (5 bytes).
SSH: Received packet SSH_MSG_UNIMPLEMENTED (5 bytes).
SSH: Negotiation failed: Rebex.Net.SshException: Key exchange failed. Requested service is not implemented. 

package 2
-----
SshSession 3.0.4696.0.
Server is 'SSH-2.0-OpenSSH_7.1'.
SSH: Sending packet SSH_MSG_KEX_30 (5 bytes).
SSH: Sending packet SSH_MSG_DISCONNECT (76 bytes).
SSH: Negotiation failed: Rebex.Net.SshException: Key exchange failed. The operation was not completed within the specified time limit.

What could be the reason for this errors?

TIA!

Hi, this is a support forum for existing or potential Rebex customers. If you use Rebex components through third-party products, please contact the product vendor for support instead.

However, in this particular case, I can at least say that:

  • The third-party product you are using is based on an outdated version of Rebex components. It's more than 4 years old. It doesn't support SHA-2, lacks Logjam attack mitigation, has outdated insecure ciphers enabled by default, and so on. Check out our release history for details.

  • Those 2 errors seem to be caused by a compatibility issue that has already been solved. Try connecting using one of our samples to make sure the latest version works fine with those 2 servers.
