Dear All, I am using latest version of click (user level ) with madwifi drivers (0.9.4) on wireless nodes running Ubuntu linux (2.6.22-14). I have setup a very simple testbed of three wireless nodes which are communicating in "adhoc" mode in 802.11b. On one wireless node, I want to record statistics of transmitted packets: retried, acked, or dropped. After going through click and madiwifi documentation (including madwifi stripped) and related mailing lists, I had written several variation of click script files to get the feedback about transmitted packets. However, I have not been successful. I have gone through lot of documentation before posting the question.
I also wanted to use old madwifi drivers (stripped) as given on the " http://pdos.csail.mit.edu/~jbicket/madwifi.stripped/";. However, the "README" file in the driver directory asks to patch the linux kernel before compiling the driver. As i could not find the required patch for the kernel (2.6.22-14) i am running, i could not try it, and have been using userlevel click. Below I am providing a simple click script file which i was using for obtaining the desired feedback. On the node where i want to record the statistics, the wireless interface is configured as ath0. FromDevice(ath0) ->ExtraDecap() ->FilterFailures() ->Print(0) -> tx_filter :: FilterTX() tx_filter[1]->PrintTXFeedback(A)->Queue()->Discard; tx_filter[0]->PrintTXFeedback(B)->Queue()->Discard; When i run this, although packets at output 0 ( tx_filter[0]) show up, however they have all filed 0 as follows. "B: 1215120504.951015 FF-FF-FF-FF-FF-FF flags 0 rate 0 max_retries 0 alt_rate 0 alt_retries 0 retries 0 virt_col 0." However, its not showing any packets on the output 1 (tx_filter[1]). I must say that i am very new to click/madwifi. I would be very happy to provide if any other information is required. I appreciate your help in this regard. Thanks Aka _______________________________________________ click mailing list [email protected] https://amsterdam.lcs.mit.edu/mailman/listinfo/click
