<div>Problem:</div><div><br></div>Linux shrew 2.1.7 (as available in Ubuntu 11.10 Oneiric) could not complete phase1 negotiation to an OpenBSD 4.8/4.9 VPN gateway; it times out. Previous version of shrew in Linux dist (version 2.1.5 in Ubuntu 11.04 Natty) completes this negotiation and connects fine, and as a workaround I have kept packages of 2.1.5 installed on Oneiric (preventing upgrade to 2.1.7).<div>
