socklog(8)              OpenBSD System Manager's Manual             socklog(8)



NAME
       socklog - small and secure syslogd replacement for use with runit

SYNOPSIS
       socklog [-rRU] [unix] [path]
       socklog [-rR] inet [ip] [port]
       socklog [-rR] ucspi [args]

DESCRIPTION
       socklog is run under runit's runsv(8), writing syslog messages it
       receives from unix domain socket path or an inet udp socket ip:port
       through a pipe provided by runsv(8) to a svlogd(8) process.

       socklog can be run as an ucspi application to listen to an unix domain
       stream socket and for more flexible distributed logging.

       If the environment variables $UID and/or $GID are present, socklog
       drops permissions to those ids after creating and binding the socket
       (not in ucspi mode).

       socklog converts syslog facility and priority information to names
       (facility.priority:) as found in /usr/include/syslog.h at compile time
       if present.

       On solaris socklog also accepts sun_stream as first argument. Please
       see the web page for details.

UNIX SOCKET
       socklog [ unix ] [ path ]

       Starting socklog with the 1st argument unix, socklog will listen to the
       unix domain socket path.  If path is omitted, the default /dev/log is
       used.

       The 1st argument may be omitted, default is unix.

INET SOCKET
       socklog inet [ ip ] [ port ]

       Starting socklog with the 1st argument inet, socklog will listen to the
       inet udp socket ip:port.

       If ip starts with 0, socklog will bind to all local interfaces.

       If port is less or equal 1024, socklog must be run by root.

       port may be omitted, default is 514.  ip may be omitted, default is 0.

       socklog prepends a.b.c.d: to each syslog message it receives, where
       a.b.c.d is the ip address of the connecting system.

UCSPI MODE
       socklog ucspi [ args ]

       Starting socklog with the 1st argument ucspi, socklog will run as an
       ucspi application. Normally socklog will only be started in ucspi mode
       by an ucspi server tool, such as tcpsvd(8), tcpserver(1) or unixserver.

       For each arg, socklog will prepend $arg: to each syslog message, if the
       environment variable $arg is present (maximum is 8).

OPTIONS
       -r     raw.  Write the raw syslog messages (no conversion of facility
              and priority) to the pipe, additionally to the log messages with
              syslog facility and priority converted to names.

       -R     raw only.  Same as -r above, but write the raw syslog messages
              only.

       -U     respect umask.  Don't set umask to 0 before creating a unix
              domain socket, but respect the current setting of umask(2).
              This option only takes effect in unix mode.
