Description of problem: vpnc connection terminates after a few idle minutes with the above error in /var/log/messages. Version-Release number of selected component (if applicable): vpnc-0.5.1-2.fc8 How reproducible: Always Steps to Reproduce: 1. Use vpnc to establish VPN connection. 2. Wait. 3. Actual results: Connection drops with error "connection terminated by dead peer detection" in /var/log/messages. Expected results: Connection maintained until one side or the other really disconnects. Additional info: New in F8 (since at least Test 2, but I didn't have a chance to isolate the problem until now).

Unfortunately this is a limitation of the DPD support in vpnc - on some connections with higher packet loss it is worse than not using it at all. You can add this line to your /etc/vpnc/default.conf to switch it off: DPD idle timeout (our side) 0 *** This bug has been marked as a duplicate of 345281 ***
