buffer/tcp configuration

[Baldomero Coll <baldo.ath9k@xxxxxxxxx>]

Hi,

I'm using ubuntu 10.04 LTS. I would like to configure my IBSS (ad-hoc) network 
augmenting the buffer sizes. I'm trying to give you more details.

I have 3 laptops in ad-hoc mode, and I transfer a file (via TCP protocol) 
between the end nodes using the middle node as relay. What i would like to do 
is to increase the middle node's buffer to allow that in case the second 
wireless link break the first wireless link stand working (until the buffer is 
filled).

I've been configuring the tcp_mem, tcp_rmem and tcp_wmem files of 
the /proc/sys/net/ipv4 folder, but it doen't result in any change.

I thought that the TCP protocol should be also configured, but i don't know 
how to configure parameters such as the congestion window.

Can you gime me some advice?

Regards, bc
