[Ipsec-tools-devel] question about syntax

[Mattes, D. <dav...@bo...>]

Hi,

When I have an IPSec SA established, I see lines in the syslog like:
racoon: INFO: IPsec-SA established: ESP/Tunnel
192.168.0.1[500]->192.168.0.101[500] spi=3D239003679(0xe3ee81f)
racoon: INFO: IPsec-SA established: ESP/Tunnel
192.168.0.101[500]->192.168.0.1[500] spi=3D745390072(0x2c6dbff8)

What does the [500] signify? =20

I'm having a situation where I will see the number in brackets at times
be 0 and at times be 500 - and when it is 500, normal traffic will not
flow through the VPN and instead I get messages like:
racoon: DEBUG: KA: 192.168.0.101[500]->192.168.0.1[500]
racoon: DEBUG: sockname 192.168.0.101[500]
racoon: DEBUG: send packet from 192.168.0.101[500]
racoon: DEBUG: send packet to 192.168.0.1[500]
racoon: DEBUG: src4 192.168.0.101[500]
racoon: DEBUG: dst4 192.168.0.1[500]
racoon: DEBUG: 1 times of 1 bytes message will be sent to
192.168.0.1[500]

Thanks!
David
