I ran iperf on Windows and Linux machine to check bandwidth speed.
Windows bandwidht speed, I explicitly set to 10Mbps/Full and Linux's BW speed is 100Mbps/Full.
Following is the strange output I got:
Client Side ( Linux Box ):
iperf -c 192.168.1.72 -r
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
Client connecting to 192.168.1.72, TCP port 5001
TCP window size: 16.0 K
I'm using tc with kernel 2.6.38.8 for traffic shaping.
Hi there,
I have a cluster of machines with two 10Gbps intel network cards on each machine. 64 port Router, with each port of capacity 10Gbps is being used.
I need to perform some network tests with iperf.
Do I need to install this on a server as well?
Do I need to open ports to run these tests?
Also, I would like to chekc the connection when connected and disconnected via VPN can I simply run it from the command line for either connection?
Just as a sanity check, please post the output of ip linkIf eth0 is present, and it is in the DOWN state, try sudo ip link set up eth0 and see if eth0 has a carrier or not. My system is running on wireless without an Ethernet cable connected to my wired port.ewaller@odin:~ 1001 %ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback
I've read that iperf basically tries to send as much information down a connection as quickly as possible reporting on the throughput achieved.
I am to use netem in order to limit the bandwidth of various ip's uplink and downlink limitations.I have created a bridge between 2 computers in linum kernel and testing it.I am using the following command but its not working.
tc qdisc add dev eth0 root handle 1:0 htb default 99
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 100Mbit ceil 100Mbit
tc class add dev eth0 parent 1:1 classid 1
Basically,I want it to do this,When
someone connects to X port it'll
let him in,But if he'll attempt
to reconnect (while already connected)
it'd block him,Say for example 1.2.3.4
is already connected to ftp on port 21
and he opens another instance
of his FTP client he wont be able to connect.
Overall i want one unique IP connected to the
port,But unique per IP (To clarify,I don't wanna limit
the p
