iLO4 Rest api or remote command line access?

Hello,

Im using  a Proliant DL380e Gen8 server. I'm looking to query the iLO console using REST Api. I keep getting a 400 error.

Url used = https://ip addr of ilo4 web console/rest/v1/Systems

Im on a redhat linux 6.5 box. How can I get the correct JSON response?

Also is there a command line scripting tool that I can use to query iLO4 console remotely? The hponcfg ulitity requires me to be on the local machine.

Thanks,
