I own a small, successful security consulting business. But by day I work for a really big company, doing really big things.

Nothing I write here represents the views of my employer, nor does it reflect any proprietary or confidental knowledge. In fact, practically all of it was written before I even started working there, so don't get too excited.

comment How to broadcast ARP update to all neighbors in Linux?
@TomTom - perhaps you just haven't been working in the right environment to see it. Sending unsolicited ARP packets is a common way to quickly re-route traffic to a new server in a failover situation. Many high-end switches and routers can take several minutes to recognize that an IP address has moved to a different physical port otherwise. Cisco switches are notorious for this.

comment Install Package dependencies separately over Cloud
Presumably you're writing a server management and provisioning system -- your "project that sets up packages on the cloud". It needs to know how to assign different servers to separate roles, such as "database server", "web server", etc.

comment Install Package dependencies separately over Cloud
You wouldn't use the server's package management system, since it's unaware of other servers. Instead, you'd bake it into whatever server management and provisioning system you're building. Or do it manually.
