Linux and Multiple Internet Uplinks: a New Tool

New submitter Alessandro Zarrilli writes: Linux has been able do multipath routing for a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux is missing a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, from a LAN perspective, it's like having a RAID-0: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking; existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new standalone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator.

Ruby??

I do not want to install Ruby on my firewall/gateway along with all of its douchebaggy dependencies and gems/crystals/unicorns/whatever-the-fuck-they're-called. This is networking, not some hipster web 2.0 app.

Re:Is it in systemd yet?

Oh just please SHUT THE HELL UP. I'm no fan of systemd and i wont use it for foreseeable future (i will actively avoid it for now) But stop injecting this trollish behavior. It adds nothing and convinces noone.

but as a network engineer, this snippet is painful to read. Inaccurate to say the very least.
