I have a centos server that was previously on my company's network using a static IP address, but it has since been blocked/firewalled on the network such that I'm not even able to ping it. I was told I was supposed to use a DHCP-issued IP, and I have since repented in dust and ashes. But now it remains to access the server and configure it to use a new DHCP-issued IP, to which I am clueless as to how to do so.
I have at my disposal, a windows laptop, an ethernet cable, network access in my company and physical access to the server. How can I go about accessing the server, and then configuring it to use a DHCP-provided IP?
What I've Tried
- connecting to the server via a LAN cable and ssh-ing in via putty. Doesn't work as I can't even ping the server even when connected via LAN.
