Running endlessh on OpenBSD

Covering IPv4 and IPv6

If you want to cover both IPv4 and IPv6 you'll need to run two instances of endlessh due to OpenBSD limitations. Here's how I did it:

  • copy the endlessh script to rc.d twice, as endlessh and endlessh6
  • copy the config file to /etc/endlessh twice, as config and config6
    • use BindFamily 4 in config
    • use BindFamily 6 in config6
  • in rc.conf.local force endlessh6 to load config6 like so:
endlessh6_flags=-s -f /etc/endlessh/config6
endlessh_flags=-s

Covering more than 128 connections

The defaults in OpenBSD only allow for 128 open file descriptors per process, so regardless of the MaxClients setting in /etc/config you'll end up with something like 124 clients at the most. You can increase these limits in /etc/login.conf for endlessh (and endlessh6) like so:

endlessh:\
	:openfiles=1024:\
	:tc=daemon:
endlessh6:\
	:openfiles=1024:\
	:tc=daemon:
