hello list members, this is regarding linux tcp implementation .. if a tcp client application is requesting large receive window using setsockopt.. and is opening multiple connections to different servers... there is a possiblity that tcp buffers might get exhausted(in scenarios where there is lot of congestion or when a server is deliberately sending only some packets in the advertised window whereby the native tcp has to buffer all these packets before passing to the user, resulting in a DOS attack). ->My question is whether linux tcp implementation deal with such situations by lowering the window sizes outgoing packets so that buffers will not get exhausted.... i have seen tcp_adv_win_scale and tcp_app_win of proc by which one can control the window sizes. ->how can one use these options to mitigate the aforesaid problems? and does this problem is automatically taken care of by linux stack... thanks and regards Syed -- Kernelnewbies: Help each other learn about the Linux kernel.
