Subject: function for getting the source ip defined in the routing table
Date: Tue, 20 May 2014 14:46:34 +0200	[thread overview]
Message-ID: <20140520124634.GM10939@kvmbude> (raw)

Hi,

i was looking for a function to get the source ip that is defined in the
routing table. I looked into the MASQUERADE module but the
"inet_select_addr" function returns the source ip from the interface
(the first one, in most use cases).

See the following routing table entry:

10.0.13.0/24 dev eth1  proto kernel  scope link  src 10.0.13.4

while the interface has multiple IPs:

    inet 10.0.12.1/24 scope global eth0
    inet 10.0.13.2/24 scope global eth0
    inet 10.0.13.4/24 scope global secondary eth0

So what i want is the value of the src part in the routing table (for connections to the related network).

thanks.
