sockopts.ini
This .ini file allows global control over the socket options that are applied when Synchronet creates network sockets.
The root section contains options that are applied to all opened sockets.
The [tcp]
section contains options that are applied to only opened TCP (so-called STREAM
) sockets.
The [udp]
section contains options that are applied to only opened UDP (so-called DATAGRAM
) sockets.
The [unix]
section contains options that are applied to only opened Unix Domain sockets.
Other sections may be defined with one or more protocol names (separated by |
) as the section name and for these sections, the socket options contained within are only applied to opened sockets for the specified protocol(s).
Options
Most of the options should not be changed by the sysop without very a detailed understanding of the effects. That said, here's the list of supported options (many are OS/Network stack dependent):
