#7 module must retry connect to server

[Badalian Slava]

Hello. Feature request.

In situation when module can't connect to destination (no route to distination) module must try reconnect later.

Example:
2 network cards. No routes. Server get routes by BGP4(quagga) at 1-3 minutes after load.

Thanks.

P.S. Why you do not send it to netfilter team? Or add to patch-o-matic repository?

Patch to get actual destinations

[Badalian Slava]

File Added: ipt_netflow-patch

[Badalian Slava]

After patch we get actual connected destinations in
cat /sys/module/ipt_NETFLOW/parameters/destination
and
sysctl -a | grep net.netflow.destination

if no have route and count of destinations is 0 - add default destination

this if i try add destination 131.131.131.131:111 and not have route to it
[12122.047005] netflow: remove destination 127.0.0.1:2055 (e2dedb00)
[12122.047056] netflow: error connecting UDP socket -101
[12122.047060] netflow: remove destination 131.131.131.131:111 (00000000)
[12122.047081] netflow: added destination 127.0.0.1:2055

if module can't create socket for connect its delete it from destinations.

It's help for me.

Thanks. I will apply them today.

About netfilter, well, is there demand for this?..

After some thinking, I see that your patch contradicting with your feature request. You are requestiong that no connect destinations should reconnect later, but your patch removing no connect destinations from 'destinations'. Thus, requested feature should keep all destinations, but patch strips wrong destinations. Now I don't understand what actually you are intending/requesting.

Any news?
With latest dev version from git now I observe following:
ipt_netflow is loaded at bootup through /etc/modules.autoload.d/kernel-2.6 (Gentoo).
At this time no network interfaces exists so ipt_netflow simply removes collectors from its configuration:
ay 13 13:05:47 linbras kernel: ipt_netflow version 1.7.1 (8192 buckets) May 13 13:05:47 linbras kernel: netflow: registered: /proc/net/stat/ipt_netflow May 13 13:05:47 linbras kernel: netflow: registered: sysctl net.netflow May 13 13:05:47 linbras kernel: netflow: error connecting UDP socket -101 May 13 13:05:47 linbras kernel: netflow: remove destination 172.16.2.7:2069 ((null)) May 13 13:05:47 linbras kernel: netflow: error connecting UDP socket -101 May 13 13:05:47 linbras kernel: netflow: remove destination 172.16.2.50:2069 ((null)) May 13 13:05:47 linbras kernel: ipt_netflow loaded.

You can set destination (via sysctl) after routes are loaded. Isn't it?
