openssh code
Hi,
How do the communication between sshd and program happens when compat20
is enabled? There are two function process_buffered_input_packets and
process_input, but in both cases if compat20 is enabled its just buffering
the packets, but how do sshd will the command to program for execution?
Regards

Defeating Timing Attacks
Hello,
In response to the timing analysis attacks presented by Dawn Song et.
al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html
we
at Silicon Defense developed a patch for openssh to avoid such
measures.
Timing Analysis Evasion changes were developed by C. Jason Coit and Roel
Jonkman of Silicon Defense.
These changes cause SSH to send packets unless request not to,
