crossbow discuss - May 2010 - Traffic shaping using remote_port ?

Hello,

I have been using Crossbow and discovering all the amazing features
associated. I have a projet that requires me to impose bandwidth regulations
based on remote TCP port and/or remote IP. I thought Crossbow would be
capable of such thing but it turns out that there seems to be a strange
restriction.

Is this possible with Crossbow ? with OpenSolaris using some other tool ?

Such thing may be possible with Linux and tc but I would really like to
avoid going down that very complicated road.

Thank you in advance for your help,

Antoine

Hi, Antoine:

You should be able to
# flowadm add-flow -a transport=tcp,remote_port=<port> -p maxbw=500 -l 
<link> tcp-flow

(You can also set based on remote_ip, but, currently, cannot
specify the protocol/port with it, see restriction is in
flowadm(1m)).

which opensolaris build are you using? The remote port went into
build 126.

If you are using on a build > 126, are you getting an error when
creating such a flow. Do you have other flows configured?

Hello,

Indeed I was trying this on a build 111. I just took a look on a build 134
and I indeed have the remote_port option. Great !

I''ll be doing only remote_port then. The collision probability will be
low
enough if outbound TCP ports really are random...

I will test this out and see how it goes.

Thank you for pointing this out and for your help,

Antoine

Hello,

I am having a lot of trouble upgrading my OpenSolaris from build 111... Would it
be possible to add just this feature into a build 111 ?

no, unfortunately, it won''t be possible to add it to 111. You might
want to check with the opensolaris installation alias etc. to see
if your upgrade issue can be sorted out.
