Hi,

I have got a linux 2.4.18 with freeswan 1.98b and x509 patch accepting W2K and linux roadwarrior connections.
All of my connections are working for a given time and then are broken and I see the following message :

I have got these problems with W2K clients and with another linux 2.4.18 freeswan 1.98b x509 patch.
Keying process should run for it self what is the problem ?

Thanks in advance
