[LARTC] allocating b/w

[LARTC] allocating b/w

[Payal Rathod]

Hi,
A majority of our work inolves ftp to my clients' side over our
slow connection. Now we need to allocate a greater b/w for this
protocol. Is there anyway I can do it using lartc easily?
Any suggestions on this please?

With warm regards,
-Payal

It can be done, but not so easy.  Ftp traffic uses some random ports.  But you 
can filter ftp traffic if you use iptables to mark all ftp traffic (make sure 
you match them all and not only the command traffic).  That mark can be used 
with the fw filter to put the traffic in a separate htb/cbq class.

Stef Coen already gave you an answer. I 'll show you another path if you wish 
to follow. It requires patching the kernel , but then you will be able to do 
packet filtering in Layer 7..

e.g.

filter all ftp traffic to HTB class 3:1 (which is 100kbps and can borrow 
unsused traffic up to 1000kbps)

see http://l7-filter.sourceforge.net/

You can also bind ftp traffic to a known range and mark those ports with 
iptables.  Thats how I do it.  Proftpd allows you to set passive ports 
to a certain range.

Well, it depends on what you mean by "using lartc" :-)

There is a "helper" match in iptables that does exactly what you need. It's
already over 2 years old so I think any quite recent iptables version should
have it (1.2.11 does).

Use like

iptables -t mangle -A wherever -m helper ---helper ftp -j MARK whatever
