Re: TLS connect error: "an EOF was observed that violates the protocol"

by Rodrigo Arias

Hi, I think there are two problems here: 1) The narkive server is sending you an EOF but not us. 2) When that happens Dillo crashes. You may be able to get some info on where it is failing by building Dillo with the address sanitizer enabled: $ git clone https://github.com/dillo-browser/dillo $ cd dillo $ ./autogen.sh $ mkdir build $ cd build $ ../configure 'CFLAGS=-Og -g -fsanitize=address' 'CXXFLAGS=-Og -g -fsanitize=address' $ make $ src/dillo https://narkive.com Then send *all the lines of the output*. I may be able to emulate an EOF and crash my own Dillo just to reproduce the issue with this information. To debug the TLS traffic you may want to get a network trace with Wireshark so we can compare it. Best, Rodrigo.

I have enabled DEBUG_PACKAGES in dillo, which unfortunately wasn't done before. Once the debug-dillo package is available (will be a few days), we might get some more insight from a backtrace with symbols... If you have a ports tree set up (with doas, etc) you can build and install it yourself: $ cd /usr/ports/www/dillo $ grep DEBUG Makefile # ensure that your tree's up-to-date DEBUG_PACKAGES = ${BUILD_PACKAGES} $ make FETCH_PACKAGES= prepare $ make package $ make INSTALL_DEBUG_PACKAGES=yes install
