[LARTC] Scenario

[Paul Caritj]

Gents,

I've been thinking about shit for awhile, but thought I might defer to 
the group: What is the best wat to establish per-user bandwidth 
throttles in an ISP-like environment using TC? I am going to have to 
support something like 4000 users and I get kernel panics if I create 
that many QDISCs :)

 Hi there, this is my first post, so please excuse me Im still new to this
 one,

 Problem description

 I have a linux router with 3 interfaces 1 goes to the internet 2MB
 Bandwidth, 2 Lan FastEthernet
 On the first Lan Interface I need to assign 1Meg of traffic to my 15 people
 on that Lan.
 So that if only 1 person is online can use the whole bandwidth, and if
 someones add it shares
 50/50 of the Bandwith, a third person would 33/33/33  and so on.
You can use the esfq qdisc to do it automatically for you.  Or you can create 
15 classes.  I think the latter is better because you will have more control.

 On my Second Lan I need to assign 768 kb to 1 user (ip adress) and the rest
 256 kb to 3 Users,
 Prioritizing ssh/telnet over www,smtp.
  So far so good, this scenario Im still trying to setup  on Lan 1 with no
 success. If someone
 can help me out with some example scripts I would appreciate very much,
Maybe you can post the script or the commands you tried so far.

  The problem arrives next month, where I will have different scenarios on
 each LAN during NightShifts.
 On Lan 1 There are going to be about 24 users prioritizing ssh/telnet
 traffic over the rest of
 possible traffics.  They are asking me to setup a DHCP Server on both Lans,
 How could I Shape or prioritize
 certain traffic to a users unknown Ip Address given by DHCP Sever? (using
 MAC Address maybe?but sometimes I
 wont have this info) other way?.

 Scenario:

2 Meg
Internet
/ \
   /   \
  / \
Lan1 Lan2
  1Meg for \
  15 users \
   \
  / \
 /   \
/ \
  768kb 256kb
 1 User 3 users ssh/telnet prio

  Whats easiest way to set up? Any example scripts?
I don't have examples that fit your needs, but I have some scripts on 
www.docum.org.  You have to translate the tree in a htb setup and that's easy 
to do.

  What to do in future if you dont know the Ip Adress of Source because of
 DHCP Server?
That's an other problem.  Maybe you can use the dhcp configuration so each 
time an ip-address is given to a pc, the tc scripts are updated.  And you can 
use the hardware address to identify the client who requested an ip.

Or use dhcpcd to bind IP's to MAC addresses.. You can do quasi-static
IP's that way.

An entry in /etc/dhcpcd.conf would look like this:

host HOST-NAME {
 hardware ethernet MAC ADDRESS;
 fixed-address IP ADDRESS;
}
