Description of problem: The problem described here occurs in RHEL 4.4 too: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=205113 For us the problem manifests itself when sshing to our RHEL 4.4 boxes. SSH causes several DNS requests to be made. Two of the requests use the same DNS transaction ID. Our firewall doesn't like this so it drops the second packet. After a 5-second timeout the request is retried, uses a different transaction ID, and succeeds. The user sees a 5-second delay when logging in via ssh. Version-Release number of selected component (if applicable): 2.3.4-2.25 How reproducible: See bug referenced above.
