Inspect Network Settings with 'netmgr'
If you are running a VMware appliance on Photon OS and the VAMI module has problems or if there are networking issues, you can use the Photon OS
netmgr utility to inspect the networking settings. Make sure that the IP addresses for the DNS server and other infrastructure are correct. Use
tcpdump to analyze the issues.
The error code that you get from netmgr is a standard Unix error code. Enter it into a search engine to obtain more information on the error.
