ssh: connect to host gw10 port 22: Connection refused

Products

• CA API Gateway

Issue/Introduction

2 gateways that were running on VM Ware Fusion Pro.

- After upgrade of my Mac to BigSur, Fusion was no longer working and I switched to Player (free).

- I restarted the gateway. For one gateway, I can remotely access it over ssh. But for the other, I have the following error message:

ssh: connect to host gw10 port 22: Connection refused

Yet, the sshd service is running, I have the ssgconfig user listed in /etc/ssh/ssh_allowed_users and the iptables seems to be properly configured (see file attached).

Anywhere else I should look at?

 

Environment

Release : 10.1

Component : API GATEWAY

Cause

On nonworking gateway "ip a" shows ens33 network interface is being mapped instead eth0 as expected to.

Resolution

1. Turn the gw off 

2. Change the MAC address of the network connection used by the VM to the one of ssg_eth0

3.  restart the gateway
