I am unable to SSH or get a local console on esxi6.5 hosts.
Vcenter Security Profile:
Incoming connections, 22 allowed from all
Direct Console UI Running
ESXi Shell Running
SSH Running
Lockdown Mode Disabled.
When I ssh, I get a "Server unexpectedly closed network connection" Wireshark capture shows 3 way handshake completes and packet #4 has fin flag from the esxi host. SSH is listening but does not get far enough to even negotiate encryption.
The above is caveated in that the ssh and esxi shell services keep stopping on me.
2. Local console problem is all I get is a blank screen when trying to use the local ESXI console. I have no problems with the DCUI, but once hitting alt-F1 all I get is a blank screen. Now if I choose to view logs, that works, which seems to use the same ALT-F1 console. I can toggle between logs and DCUI using the F keys.
I'm a bit stuck here, cannot SSH into box, ssh services will not stay running, and unable to get any kind of display trying to use local console. (Monitor and Keyboard directly attached to ESXi host) I have full management of the device via Vcenter and Esxi Web console. Any thoughts or suggestions on where else I can look to resolve this issue? This box has been hardened per DISA STIGS with a bunch of lockdowns to the SSH configuration file. I am wondering if there may be a problem with the sshd_config file but I am unable to get to it to inspect.
