[iodine-users] Error: Discarded data, uncompress() result: -3

[Shervin Khastoo]

I believe that is not the case. Packets that are not being fragmented
(short packets) reach the server correctly. Also, I investigated some of
the packets manually by running the Wireshark both on the server and the
client and packets were the same.

It's just so weird. I can download a file from the server via wget (because
it has small http headers and no packet will be more than 255 bytes), but I
cannot view that page in chromium (because of the large headers and the
fragmentation).

By the way, I'm using the last version in the repos on archlinux. Could it
be something like the incompatibility between zlib and iodine? is anyone
running iodine on the latest archlinux?

Also, I am currently forwarding requests to iodine via bind. I tried
removing bind and running the iodine directly on port 53 but the problem
still persisted. But in "raw udp mode" the problem is gone.
