IPv6 copy problems

Relevant classes: any Cfengine version 2 supports the `Next Generation' IPv6 protocol for client-server communication. Cfengine selects ipv6 transfer if both hosts in a connection support it. This occurs automatically. In copying between 2 linux 2.2 kernel machines, I have seen problems where the connection hangs for no reason. I assume that this is an implementation bug, since everything looks fine from the cfengine side. If this occurs, you can use forceipv4=true to avoid the problem. Back to documentation
