IpFreeBind

Controls Linux IP_FREEBIND socket option for nonlocal binds.

This parameter applies to imudp: UDP Syslog Input Module.

Name:

IpFreeBind

Scope:

input

Type:

integer

Default:

input=2

Required?:

no

Introduced:

8.18.0

Description

Manages the IP_FREEBIND option on the UDP socket, which allows binding it to an IP address that is nonlocal or not (yet) associated to any network interface.

The parameter accepts the following values:

  • 0 - does not enable the IP_FREEBIND option on the UDP socket. If the bind() call fails because of EADDRNOTAVAIL error, socket initialization fails.

  • 1 - silently enables the IP_FREEBIND socket option if it is required to successfully bind the socket to a nonlocal address.

  • 2 - enables the IP_FREEBIND socket option and warns when it is used to successfully bind the socket to a nonlocal address.
