Need a way to override hardcoded max UDP message size of 9012 #357

Open frs3 opened 2 years ago

frs3 commented 2 years ago

The max UDP message size is currently hardcoded to 9012. We would like to increase it, since our max workload message size is greater.

Quick fix:

export CHISEL_UDP_MAX_SIZE=12000

share\tunnel\tunnel_out_ssh_udp.go:80 share\tunnel\tunnel_in_proxy_udp.go:83

const maxMTU = settings.EnvInt("UDP_MAX_SIZE", 9012)

or command line param e.g. --udp-max-size 12000

why don't you create a pull request?

It should probably read const maxMTU = settings.EnvInt("CHISEL_UDP_MAX_SIZE", 9012). Or as you said, use a command line param. Does chisel/go have a library (integrated) that allows both? Might be useful to be able to provide all commandline options via env. variables (or a config file), whatever is most convenient.

Yep happy to put max MTU behind a env setting
