I recently encountered some connectivity issues while working from home and trying to access some corporate resources. Notes for myself on some tips our infosec team shared to troubleshoot the Zscaler client since all the traffic to the interweb gets routed through it.
- http://speedtest.zscaler.com/perf
- Gives you an overview of which Zscaler pop you are connecting to and access speed to the Internet via that pop.
- http://127.0.0.1:9000/?ztest?q=@YOUR-CORPORATE-DOMAIN (ex: google.com)
- This provides a detailed report, including:
- DNS Reachability Test: Confirms if DNS is resolving correctly.
- UDP Connectivity Test: Checks if UDP packets can pass through.
- TraceRoute to Zscaler: Shows the path your data takes to reach Zscaler.
- Throttling Test: Identifies any speed drops.
- Download/Upload Bandwidth: Measures the speed at which data transfers.
- This provides a detailed report, including:
- https://ip.zscaler.com
- A quick utility to check where and how your traffic is routed through the Zscaler network. Very similar to the perf test data, but doesn’t let you run a performance test.
