922af308f2 Systemd service 
Assuming an /opt/ install. For those unfamiliar, plop it into /etc/systemd/system (symlinks might not work, old systemd bug), run `systemctl daemon-reload`, and have it start on boot (and immediately) with `systemctl enable --now endlessh.service`

7ac1fbff3b Always ignore SIGPIPE 
MSG_DONTWAIT doesn't work quite right on OmniOS / Solaris, so also
disable SIGPIPE.

2bd2b3ca92 Just drop IPV6_V6ONLY (it never works right anyway) 
This doesn't seem to work as documented on any system.
 2019-02-03 15:28:09 -05:00
Christopher Wellons
08a9dfe97e Check for IPV6_V6ONLY before using it 
This is necessary for supporting OmniOS (Solaris), which doesn't
actually document how to actually define this flag. This platform also
requires LDLIBS='-lsocket -lnsl' when compiling.

93b94f6b44 Correct for different definitions of sockaddr_in 
On BSD it doesn't like the braces, and on Linux it prefers braces. Ugh.
