Ticket ID: SIXXS #848488 Ticket Status: Resolved PoP: deham01 - Easynet (Hamburg)
No Connection to Endpoint
![[de]](/s/countries/de.gif) Shadow Hawkins on Friday, 14 November 2008 15:31:37
Hey there,
Today there were some problems with PoP deham01, so that the status of that PoP changed to kind of 'not working'.
Anyway, as it is now marked as 'Enabled' I tried to stop aiccu and start over again.
The deamon stoped, the device sixxs went down and went up again after /etc/init.d/aiccu start.
Unfortunatelly theres no aiccu deamon after that anymore. And I can't ping neither ipv6.google.com nore my Endpoint.

Anything wrong with my setup or still something wrong with the PoP?
Thx for your help

It's not the firewall .. just deaktivated it .. no change
Did I mention the aiccu deamon ist not running in background .. after start its says (debug):

I dont understand this message:
sock_printf() : "QUIT Don't Leave"
No Connection to Endpoint
Of course it quits, it does not need to do anything else than configure the tunnel, it is a static tunnel after all.

Ah .. I see. Sure no need for a deamon ;)

That definitely is wrong, unless you really want yourself to be your own endpoint.
Please check with "ip tunnel show" how the tunnel is configured. You might want to use "ip tunnel del sixxs" to delete this broken tunnel and then run aiccu again.
AICCU does not fix broken setups, as it can't know that maybe that kind of configuration was intentional or not.

Clearly the packets don't even go out.
Please actually read the full "reporting problems" list and provide all the details.

Sorry for the inconvenience.
It's been the ip4tables ..
now allowing all ipv4 traffic to the endpoint and everthing runs fine.
i've been so stupid.
