Errors and fix's

wsl2 dns broken by windows

powershell to find dns servers in use by windows

$x = Get-NetAdapter | Group-Object -AsHashtable -Property ifIndex;
Get-DnsClientServerAddress -AddressFamily ipv4 | where {$x[$_.InterfaceIndex].Status -eq "Up"} | Select-Object -ExpandProperty ServerAddresses | foreach {"nameserver " + $_}

wsl2 windows keep replacing /etc/resolv.conf - prevent it with /etc/wsl.conf

echo "[network]" > /etc/wsl.conf
echo "generateResolvConf = false" >> /etc/wsl.conf

mv, even as root, gives error under Windows WSL2
- possible WSL Windows bug, locking files.
- Workaround: Close vscode and all WSL windows, open single terminal and do mv / rename
Can't ssh - Blocked by FW ??? - https://github.com/microsoft/WSL/issues/5755
