Route SSH connections through HAProxy using the SSH ProxyCommand feature and SNI. Did you know that you can proxy SSH connections through HAProxy and route based on hostname? The advantage is that you can relay all SSH traffic through one public-facing server instead of needing to grant users direct access to potentially hundreds of internal servers from outside the network.
Networks are rapidly becoming larger and more complex, with numerous different technologies playing into their expansion. Network mapping is increasingly important for network administrators tasked with handling these growing networks. Network mapping provides network admins with a visual map so they can check network performance, the status of connected devices, monitor the network, and analyse networks before initiating troubleshooting efforts.
This week, an unfortunate incident got reported by the cybersecurity firm FireEye. According to FireEye, FireEye’s system was hacked via a product they were using, called Orion. Orion is SolarWinds’ most popular product, bringing in more than 50% of their revenue every year. It is believed that hackers funded by foreign governments compromised the networks of both public and private organizations via their SolarWinds monitoring service.
Persistent connections allow HAProxy to optimize resource usage, lower latency on both the client and server side, and support connection pooling. HTTP is a layer 7 protocol that’s transmitted over a TCP connection. It works in a client-server model and follows the request-response paradigm, which means that a client sends a request to a server, which then replies with a response. From this statement, you can infer two different ways of operating.
