ssh hangs at SSH2_MSG_KEX_DH_GEX_INIT sent
by bbraml from LinuxQuestions.org on (#5GB9N)
I have 15 RHEL6 servers in 2 locations and another server in a third location that needs to ssh to those servers. That one server cannot successfully ssh to the other servers, except 1. I ssh using verbose and see that it gets to debug1: SSH2_MSG_KEX_DH_GEX_INIT sent and hangs
Checking the logs on the other servers, I see no messages until I CTRL C to get out of the hung ssh. Then I see, Connection closed by 10.10.10.10. Nothing else in messages and nothing in secure.
All of the 30 servers this one is trying to connect to are kickstarted and patched with the same OS.
I've searched the googles and have not found anything that can help. I'm looking here to see if you can. Thanks
