An exercise in "What If I wrote tcproxy in Go?"
Currently this is just "an exercise". If you want to use it for something real, you might want to first drop me a line so I take the time and care to harden the program!
brew tap lestrrat/gtcproxy
brew install gtcproxy
See the releases page
go get github.com/lestrrat/gtcproxy
gtcproxy "11211 -> 11212" // proxy port 11211 to 11212
gtcproxy "127.0.0.1:11211 127.0.0.1:11212" // same, with explicit IP
