[Openswan Users] openswan-3.0.01 crash

Tue Nov 28 08:19:46 EST 2006

Hi all,

I'm trying to test openswan-3.0.01 using the following testbench

Client1 -------------------------------------- Linux gw1
---------------------------------- Linux pc
-------------------------------- Linux gw2 -------------------------
Client2

172.16.0.2/24

                            172.16.0.1/24              192.168.1.1/24

192.168.1.2/24   192.168.2.2/24

192.168.2.1/24     10.0.0.1/24

10.0.0.2/24

On Linux gw1 and Linux gw2 I run ipsec start

Then I run ipsec auto -up net-to-net on Linux gw1

This command causes a Pluto crash on Linux gw2.

Following there is my ipsec.conf, ipsec.secrets and the result of the
gdb /usr/local/libexec/ipsec/Pluto core.xxxx
