Increase max connection in redsocks proxy

abjadhoz · August 15, 2024, 1:58pm

hi i have a busy network and want increase max_conn more than 128 in redsocks there is any way for more connections,here is something but i was unsuccessful to change 128 max_conn in redsocks my network is unstable lots of connection drop

github.com

darkk/redsocks/blob/master/redsocks.conf.example

base {
	// debug: connection progress
	log_debug = off;

	// info: start and end of client session
	log_info = on;

	/* possible `log' values are:
	 *   stderr
	 *   "file:/path/to/file"
	 *   syslog:FACILITY  facility is any of "daemon", "local0"..."local7"
	 */
	log = stderr;
	// log = "file:/path/to/file";
	// log = "syslog:local7";

	// detach from console
	daemon = off;

	/* Change uid, gid and root directory, these options require root

in line 85
// listenq = 128; // SOMAXCONN equals 128 on my Linux box. what is this line

          	// If `splice` is enabled, it also needs four file descriptors for
          	// pipes.  `redudp` is not accounted at the moment.  When max number of
          	// connection is reached, redsocks tries to close idle connections. If
          	// there are no idle connections, it stops accept()'ing new
          	// connections, although kernel continues to fill listenq.
          
          	// Set maximum number of open file descriptors (also known as `ulimit -n`).
          	//  0 -- do not modify startup limit (default)
          	// rlimit_nofile = 0;
          
          	// Set maximum number of served connections. Default is to deduce safe
          	// limit from `splice` setting and RLIMIT_NOFILE.
          	// redsocks_conn_max = 0;
          
          	// Close connections idle for N seconds when/if connection count
          	// limit is hit.
          	//  0 -- do not close idle connections
          	//  7440 -- 2 hours 4 minutes, see RFC 5382 (default)
          	// connpres_idle_timeout = 7440;
          
          	// `max_accept_backoff` is a delay in milliseconds to retry `accept()`

ulimit -n results in 1024 by default, you need to rise that.

SOMAXCONN is new connection queue for service, exceeding it must be logged in dmesg

hi i use this configuration and speed get wild

base {
log_debug = off;
log_info = off;
log = stderr;
daemon = on;
redirector = iptables;
redsocks_conn_max = 4096;
connpres_idle_timeout = 7440;
max_accept_backoff = 6000;
}

redsocks {
local_ip = 127.0.0.1;
local_port = 12345;
listenq = 4096;
splice = true;
ip = 127.0.0.1;
port = 10808;
type = socks5;
}

Wrong answer.
