Hi Bart, I have some similar problem over here with Ubnutu Karmic: Most of the time it works without thought, but from time to time it just won't start. Syslog/messages just tell me that Aiccu "Couldn't retrieve first tunnel for the above reason, aborting" but it gives no reason to be above. Very uncommunicative for a unix tool... However, I found out that sometimes it wouldn't start because it couldnt query any (IPv4) Nameserver to ask at that time, because DHCP had not replied with one yet. Manual setup of an NS in resov.conf helped. Alternatively, a static entry for the tic-server in hosts could also fix that. But on ther times when it doesn't start, I cannot figure out any reason, and the hint to 'above reason' gets quite sarcastic with time. Today I found that killing an arbitrary process which had the string "aiccu" as parameter helped. Looks like aiccu just greps if ps outputs anything with aiccu and then aborts without any more information. Well, I'll keep observing that when it fais next time. /Flo

I did put it in non-deamon and verbose mode, but all it did was print to screen what it would do to the log, and aiccu happened to be in verbose mode already somehow, so I wasn't getting any further information. I googled though for ways to retrieve more information, but I couldn't find any other ways. The DNS problem sounds familiar, my gateway somehow refuses to forward any DNS queries sent to it. The solution I found to that was setting the DNS server addresses in the resolv.conf file, though I suppose that wasn't enough. The tunnel works now, so I'm going to leave it as it is (same configuration as when it stopped), and I'm not going to touch it, until I really need to. Thanks for the help I received, and if you can tell me where I can find more details, I'll bring them back here, for I don't know where to look for them.
