Thought I’d ask two in one thread 
How do resources get evenly distributed across all accounts? Is there a way to make sure one account doesn’t suck all resources?
And is there an easy way to whitelist multiple IPs server wide not just per account?
Thanks
No , it doesn’t limit on OLS by itself, you will need to have something like CloudLinux LVE manager, though there is a feature in LSWS to limit it without CL.
what exactly do you want to do ? if you just want to white list some IPs, you can directly add them to firewall in panel.
