Comment 55 for bug 93413

This is also reported in Debian (I added the link)

As for the development, they know about it, from their website (http://www.unix-ag.uni-kl.de/~massar/vpnc/) "Known Bugs vpnc looses connection with some targets, even before the rekey-timer expires most probably due bugs with keepalive, dead-peer-detection or something else..."

There is also a development mailing list, http://lists.unix-ag.uni-kl.de/pipermail/vpnc-devel/
This bugreport gets mentioned at least twice there: http://lists.unix-ag.uni-kl.de/pipermail/vpnc-devel/2007-April/001474.html and
http://lists.unix-ag.uni-kl.de/pipermail/vpnc-devel/2007-April/001470.html
but it does not seem to get really much attention.

This http://lists.unix-ag.uni-kl.de/pipermail/vpnc-devel/2007-April/001498.html seems to be a patch that does the same as James Tait's, but I am no coder so I cannot tell. If they do the same, I guess it would be better to use that rather than yours, could you please look at it (and if it is different, try ti submit it there, so that everybody can benefit from it, not just Ubuntu)

Now, there is a lot of new features so downgrading is not an option. However, I think that applying the patch is too much hassle, since it needs changes in other package (network-manager-vpnc) as well. And even if it were fixed there, how should people know they need to disable DPD? I think that it will be much easier to just revert the 06_stolen_from_head.dpatch to get this repaired for Feisty. We now only need someone (probably from MOTU) with enough privileges to push this further, I am afraid.
