An SSH service that provides secure and encrypted connections to traditionally non-encrypted services, such as e-mail or news. SSH port forwarding allows you to establish a secure SSH session and then tunnelTCP connections through it. It works by opening a connection to forward a local port to a remote port over SSH. The client software (e.g. your e-mail client) is then set to connect to the local port. With SSH port forwardingpasswords are sent over an encrypted connection. Also called SSH tunneling.
Fixing Tanzu Kubernetes Pod to External Services Connectivity Issues with NSX-T Last month I got a call from a customer who was pulling their hair out over a networking issue. They had just deployed VMware Tanzu Kubernetes Grid on their vSphere with Tanzu environment, everything looked good in the dashboards, all pods were running, but their applications inside the pods could not reach external databases running on traditional VMs in the same datacenter. The frustrating part was that some pods could reach external services perfectly fine, while others would just timeout. There was no clear pattern. Let me tell you how we figured this out and fixed it. The Initial Problem Here is what the customer setup looked like: vSphere 8.0 with Tanzu enabled NSX-T 4.1.2 for networking Three Tanzu Kubernetes clusters running different microservices applications External PostgreSQL database running on traditional VMs (non-Kubernetes) External API services running on another se...
