[lwip-devel] Question about predictable TCP sequence numbers

Hi,

We tried nmap on lwip on L4. It doesn't recognize the OS, that is
normal :). However, it tells that TCP ISS are predictable (0 - trivial
joke). We tried to use avege pseudo-random number generator into
tcp_next_iss function. But result is the same.

Does anybody know something about it ?
Regards
Marc
