title: disabling linux tcp receiver window auto tuning
body: <p>I'm working on <code>linux (2.6.43.8-1.fc15.i686.PAE)</code> and face some problem to disable auto tuning of the TCP receiver window.</p>
  
  <p>I'm trying to find a given setting that would force my client to advertise a fixed receiver window. I tried to give a same given value to <code>net.core.rmem_max</code> (/proc/sys/net/core/rmem_max) and <code>net.core.rmem_default</code> (/proc/sys/net/core/rmem_default) as well as <code>ipv4.tcp_rmem</code> (net.ipv4.tcp_rmem) but when checking the advertised window (using wireshark) it's absolutely not changing anything....</p>
  
  <p>This is for a study of TCP behavior and I would be very greatful if someone could answer me</p>
  
  <p>Thanks in advance</p>
  
  <p>PS: I made use of <a href="http://www.cyberciti.biz/faq/linux-tcp-tuning/" rel="noreferrer">this post</a> to tune the parameters </p>
