Unable to ssh to slave node

JonEtkins

I have two UTM VMs running as a high-availability pair.  I need to check something on the slave/standby node, so I'm attempting to SSH to it by means of the ha_utils ssh command from the master/active node.  I'm SSH'd in to the master as root using an ssh key, but when I try to connect to the slave I get Permission Denied.

<M> astaro:/root # ha_daemon -c status
Current mode: HA MASTER with id 1 in state ACTIVE
-- Nodes -----------------------------------------------------------------------
MASTER: 1 esxi3 198.19.250.1 9.705003 ACTIVE since Mon May 10 10:26:56 2021
SLAVE: 2 esxi55 198.19.250.2 9.705003 ACTIVE since Mon May 10 10:31:57 2021
-- Load ------------------------------------------------------------------------
Node  1: [1m] 0.00  [5m] 0.01  [15m] 0.05
Node  2: [1m] 0.01  [5m] 0.02  [15m] 0.05
<M> astaro:/root # ha_utils ssh

Connecting to slave 198.19.250.2
loginuser@198.19.250.2's password:
Permission denied, please try again.
loginuser@198.19.250.2's password:

<M> astaro:/root #

I know I'm using the correct password for loginuser - I've even changed it via the web UI to be sure I wasn't misremembering, but to no avail.

Any thoughts or suggestions welcomed.  Thanks!

    Hi ,

    Thank you for reaching out to Sophos Community.

    If 'Block Password Guessing' is enabled under Definitions & Users > Authentication Services > Advanced, then the slave node might have temporarily blocked access from the master node's IP address due to failed login attempts.

    Could you please try again and share your observation?

    Hi Yash, and thanks for responding.  Yes, I have blocking enabled, but I also have my workstation added to the "Never block networks:, so I doubt that is the problem.  I get the same result regardless of which node is currently active, by the way:

    Hi  .

    One thing. I doubt that putting your workstation to the "Never block networks" list would help. You could put in the network of the HA connection, because with ha_utils your connection should normally occur using the HA port, as far as I know.

    You could give this a try.

    But be careful as the HA IP is a public IP you should not use this generally.
