Bob Lantz c58bb42f57 Added updbwgraph, a demo of how to graphically monitor node output. 2010-04-10 19:28:18 -07:00
Bob Lantz afe0ce81a5 Added simple console tool demo.

Bob Lantz b5672f1565 Cleaning up read/monitor/interrupt. 
Now you don't need to specify a default read count.

Now, by default, we print the pid out in sendCmd() which allows us
to snarf it later and set lastPid correctly.

Now, we wrap os.kill() in a try block, so that if the process is
already gone we don't get an exception.

Bob Lantz b2ef87ae51 Changes to pass code check. 
We should check NOXController and RemoteController to make sure that

Bob Lantz c70aab0a38 Changed mininet.link() to mininet.configLinkStatus(src,dst,status) 
Also rearranged parameters in link command to

mininet> link s1 h2 up

To resemble ifconfig a bit more.
 2010-03-23 15:25:12 -07:00
Bob Lantz fb2f652319 Changed mininet.link() to support multiple links. 
It should also probably be renamed to something like:
configLinks(src, dst, status).

Bob Lantz 8abc3472e3 Pass code check. 2010-03-16 14:59:46 -07:00
Bob Lantz ec7b211c41 Buffered output. Added net.monitor() and node.readline() 
Moved monitor() and readline() into net.py and node.py respectively,
which will hopefully be useful for monitoring large sets of hosts,
as is done in udpbwtest.py.

Changed iperf to use interactive command infrastructure (such as it
is), which may make it more reliable. Hopefully it's a bit clearer
as well, although it is slightly more complicated.

Bob Lantz bcacfc0510 Support for control-C. Finally. 
I've changed the way things work a bit:

1. netns is replaced by mnexec, a general-purpose mininet helper.

2. For interactive commands, we now use mnexec -p, which prints out
   the pid, so we can kill it when someone hits control-C!

3. We close file descriptors for subshells. This might save memory,
   but who knows.

4. We detach our subshells from the tty using mnexec -s; thus
   control-C should not terminate everything.

5. Given 4, mn -c is now necessary if you kill mininet.

Bob Lantz 4065511abb Detach shells from tty; monitoring changes. 
Call netns using setsid to detach from the tty; this is
intended to fix the problem of control-C killing your network.

sendInt() doesn't actually work - hopefully we can fix this in the
future, but it's tricky since we want to detach the many shells from
our tty, but then optionally send tty interrupts to them! Ideally we
would either know the pid of the subprocess or be able to send a signal
to bash to get it to interrupt its subprocess.

waitOutput() now uses monitor. We also handle sentinels
coming in the middle of output (but default at end should
still work well.)

Bob Lantz d44a5843d3 Reinstantiated inNamespace and routed control network. 
We need to figure out how to specify the IP addresses for the
routed control network. For now I'm going back to 192.168.12x.y

Also changed controller params to use IP strings rather than
numbers. However, we still need to clarify what ControllerParams
is actually for.
