Hello Jiri While integrating your man-pages patch for IP_NODEFRAG, I noticed that this option is settable by setsockopt(), but not gettable by getsockopt(). I suppose this is not intended. The (untested, trivial) patch below adds getsockopt() support. The patch is against 2.6.36-rc3. Cheers, Michael PS I've just configured Thunderbird on this machine, hopefully the patch is not mangled. Please let me know if there are problems.
