I am using Iperf 2.0.4 on linux 2.6.32.10 loaded in two Mikrotik
Routerboards 411AR.
I tried to run iperf in these two boards through serial connections from
the
boards to my laptop via minicom and measure the 802.11 performance.
When I run iperf tcp test setting one board as server and another as
client, I can see only
the following message:
root@OpenWrt:/# iperf -s
------------------------------
------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 4] local 192.168.1.20 port 5001 connected with 192.168.1.6 port 41061
root@OpenWrt:/# iperf -c 192.168.1.20
------------------------------------------------------------
Client connecting to 192.168.1.20, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.1.6 port 41061 connected with 192.168.1.20 port 5001
At this point, the client hangs and the results are not displayed, not even
much later
than 10 secs. Sometimes, the results are displayed after arbitrary time
intervals like
17.4 secs, 1092.2 secs and so on.
UDP works fine. I get the results exactly after 10 secs.
Can somebody identify the problem behind this and also suggest an
appropriate
solution?
