dns packets from different servers #108

No, it does not fix it. :-( I tried 0.0.7 release. But I saw there are no changes in 0.0.8 regarding this problem. I alos get some of these errors, when I use my providers DNS server.
When I use my own DNS server, it works fine but resolving via provider DNS servers is free. ;-) |
Then I am not sure what problem you are having. Does it work if you specify your server IP as the nameserver in the client? What command line arguments are you using currently for server and client? (You can anonymize the domain). Can you also post a log from the server when this happens, with |
On client I tried following ways.
and this on server:

The bad version logs from the server look very strange. Can you attach (or email me) a pcap file containing the packets that cause them? But they should not disturb any established session - so things should still work even if that happens |
Ok, I will try to log. But this only occurs on the new DNS servers by the provider. In former times, when the provider did not use a load balancer for DNS requests and my server got all requests from one IP address, it worked fine. I also trief to reduce the MTU but it did not help. Here you can see the debug information while I got one error entry about "Bad version".

client starts well:
When I start a rsync command via the tunnel, the ping gets worst and then I get soem of this messages on the server.
when there is no data transfered through the tunnel, the pings sty stable without loss and then I also do nt get any errors in the logfile. I am quite sure, that my provider drops some packets. Is it possible to open the iodine client with only openening 5 or 10 requests at the same time? A flag for iodine client for maximum DNS requests per second would be fine. So the bandwidth could be controlled and it will work with more providers. |
Hi,
I noticed that my provider started a dns load balancer, so the iodined server get requests from two different sources.
This interrupts the dns tunnel very often.
Why is it not possible to buffer packets on the iodined server so that it does not matter, if dns packets comes from one source or from two sources?
Thanks, very much.
