Regarding actual Noise values

Hey all,

I was trying to get noise values using RXStats. We find that rate and RSSI
values are displayed but the noise value is always 0. We are using Atheros
device driver and its a university setting with people around. We have used
AthdescEncap and AthdescDecap. We also tried using Prism2Encap and
Prism2Decap but it still gives noise value as 0.

Re: help about fromdevice

Hi,

You will need to use ToDump and specify the pcap file location as a
parameter in your Click configuration, have a look at
http://read.cs.ucla.edu/click/elements/todump

Re: Mac OS X assert failed when trying to use KernelTun

Pekka,

Thanks so much!!  This is excellent.  I've checked it in with a couple 
edits to the documentation.

Re: AODV and OLSR implementations

Dear Michael and PATS,

This is fantastic!!  Thank you so much for making this available.  And I 
love, love, love to see new Git repositories :)

Attached are two patches for the AODV elements to bring them up to date 
with mainline.  The first uses cp_va_kparse; the second switches 
Timestamp in for timeval.  I hope they are useful.

Any chance we can format these as a package?  What would be the best way 
to get them used?

Eddie

Re: [PATCH]: radiotapdecap.cc: pull the correct amount of bytes on big-endian

Hi Eddie -

If you are in the mood to patch radiotap elements, I submitted some 
patches a few months ago that I don't think were ever applied (and if 
the patch was rejected, I didn't hear that).

This is the original email (verbose explanation at the top, patches at 
the end):
https://pdos.csail.mit.edu/pipermail/click/2009-August/008190.html

Help, Fromhost

Dear all, 

I have a problem about fromhost when I use Click in USERLEVEL. I want to use Click's StaticLookup to realize a
router, but it works just well when the rouer just work as a 'bridge' , for example, two hosts connecting to
the router will ping each other well, but when the two hosts connecting each other with two Click
Statictable routers , the host will not ping the farther router. I found it is the problem of FromHost. The
element of FromHost.u for userlevel is the same with that for kernel level. How could I use FromHost.u for
userlevel ?

The topology of my experiment is as follow:
E(IP:10.0.5.3)---------(IP:10.0.5.2)C(IP:10.0.4.2)---------(IP:10.0.4.3)B(IP:10.0.6.2)----------(IP:10.0.6.3)F
When F(10.0.6.3) ping E(10.0.5.3), F will get reply, when F ping C (10.0.4.2), F will get nothing.

The script of C is as follow:

//eth0     10.0.3.3  00:27:19:91:28:22  
//eth1     10.0.4.2  00:27:19:90:E6:1B  
//eth2     10.0.5.2  00:12:3F:C4:7B:18  

ip :: Strip(14)
    -> CheckIPHeader(INTERFACES 10.0.6.2/255.255.255.0  10.0.2.3/255.255.255.0 
10.0.4.3/255.255.255.0)  // here needs reconfigured, all ip/netmask of the three devices
    -> Print("before1 rt")
    -> IPPrint
    -> Print("before2  ")
    -> rt :: StaticIPLookup(
        10.0.3.3/32     0,
        10.0.4.2/32     0,
        10.0.5.2/32     0,
        // to networks

Re: AODV and OLSR implementations

Dear Eddie,

You are welcome! The two patches have been applied and pushed to github, just pull to make them available. We
are still learning git step-by-step, this is why you will notice that the first patch was not properly
signed off. My apologies for that, I did not discover how to use git-reset or git-revert to do that.

These elements have been tested in a number of setups before, so you should be able to use them quite quickly.
How would you like to integrate them as packages? For now we have patched some of the configure files to get
the package setup done.

best regards,
Bart

Build Clicky with non-root permissions?

Hi,

Is it possible to build Clicky with non-root permissions? I have tried to use the prefix option to
configure, but it still refuses to recognise my Click installation.

On a related note: I tried click-pretty and noticed it does not use internal element names as labels. Am I
missing a flag to enable this or should I try patching this in?

Best regards,
Bart
