site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com (off list) Hi Andre, I'll take another look. Currently I have, as a LaunchAgent: but that will launch aiccu even if tun/tap is not ready. I'll do some more digging.

I obviously did look hard enough, since I has tried searching on the developer web site before posting the question. I'll have another look. I'll certainly check the Darwin source, which I hadn't thought of doing before. Your understanding is a bit far afield in that your launchd plist isn't a script and doesn't have a timeout or anything like that. If you just want an application launched, you just tell launchd "launch this application with these parameters" and (optionally) relaunch it if it crashes. This is the delicate part, since if does crash I need to limit how soon, or how many times, it attempts to reconnect. Part of the contract with the tunnel provider is that I don't reattempt to reconnect too many times, too quickly in the case of issues. Doing so would result in the tunnel end-point locking me out. The program I am trying to move to launchd is not one which I wrote, so I don't have much control over its behaviour. If you provide a service, you can tell launchd to register the service (TCP port, unix domain socket, whatever) on your behalf and launch you if anyone accesses it. When you're launched, you check in with launchd to get your file descriptors then open whatever services you need, which may cause launchd to launch them on demand. This is possible, but I am not sure how well this interacts with a service that is currently being launched using a StartUpItem, which tun/tap is. Anyway, hopefully this will give you a kick in the right direction. Look at the docs and "man launchd.plist" to get started.
