[LARTC] Question

[bkonosky]

<PRE>I'm needing to do both QoS and NAT on a network. Also the router box itself has
a program running on it that needs bandwidth...I need to make sure that the
people on the NAT side has 90% of the bandwidth though...If need be I can
offload the program onto another box, and work that way, but I'd prefer to keep
the number of boxes there to a minimum...

THanks

[=?unknown-8bit?q?Gast=C3=B3n?= Forbice]

Hi,
  Actually my question isn't too hard. I've red the "Advance Routing & 
Traffic Control How to", but it isn't clear to me where the routes are 
keept. Since you do specify the location on which the rules are stored 
(/etc/iproute2/rt\_table), I hope you can clear this up for me.
Thank U.

This differs per distribution. Check the documentation that came with it.

                                                    Hi,

I have that schema:

                                                   Linux box
                                              ======
Outside world  <-----------> eth0              eth1 <--------------->
Inside world
                                              ======

On both, eth0 and eth1 I have a HTB queue applied. The filter is applied
on the net 10.1.1.0/24. From the Inside world a need to reach some
computers from the Outside world, the net is 172.16.45.0/24. My question
is: in condition that I don't have any other filter applied on the net
172.16.45.0/24 that traffic will be gone at full speed through my Linux
box ?

Thank you,
Liviu

I don't understand what you want to say.  But if you don't have any filters 
but you do have a htb setup, the traffic ends in the default class if you 
specified one.  If you don't have a default class, the packets are 
transmitted as fast as the link allows.

[LARTC] Question

[Edgar Estrada Lopez]

Hello:

I need some help on split access and load balancing:

I have 2 xDSL (eth1 @ wireless broadband modem;  and ppp0, actually 
connected to eth0 on a phone DSL).

Both links have dynamic addresses.
I was reading the examples in the HOWTO:
--- copied from the howto ---

	  ip route add $P1_NET dev $IF1 src $IP1 table T1
	  ip route add default via $P1 table T1
	  ip route add $P2_NET dev $IF2 src $IP2 table T2
	  ip route add default via $P2 table T2
--- end copy --

this is awesome... is there any script that could convert these vars 
($P1_NET, etc) into the REAL values of my 2 dsl connections?

I'm still not too good at coding in Linux... can anyone help me?

Thanks in advance

Edgar

Since nobody else volunteered:

--cut here --
#!/bin/sh
IFCONFIG="/sbin/ifconfig"
ROUTE="/sbin/route"
IF1="ppp0"
IF2="eth1"

# returns the IP address and netmask assigned to the interface
  IP1=`$IFCONFIG $IF1 2>/dev/null | grep inet | cut -d : -f 2 | cut -d
\  -f 1`
  MASK1=`$IFCONFIG $IF1 2>/dev/null | grep Mask | cut -d : -f 4`
  echo "$IP1/$MASK1"

# returns the network IP address and netmask per the routing table
  MASK1=`$IFCONFIG $IF1 2>/dev/null | grep Mask | cut -d : -f 4`
  P1_NET=`$ROUTE -n | grep $IF1 | grep $MASK | grep -w "U" | cut -d\ 
-f1`
  echo "$P1_NET/$MASK1"

# CAVEAT:  The interfaces must already be up.  Some error checking would
be advisable.  E.G.:

if [ "$P1_NET" = "" ]; then
    echo "no routing entry found for $IF1.  Aborting."
    exit
fi
-- cut here --

You might also look to see if information can be obtained from
/etc/ppp/ip-up.local or /etc/dhcpc/dhcpcd-eth1.info.

[LARTC] Question.

[Ben]

<PRE>I'm trying to do QoS and NAT at the same time...The router box is
needing to use some of the bandwidth itself, but I don't want it to take
more than 10% of the bandwidth...I'm looking at the howto, but I'm not
sure how to make it choke the local box itself.

If needed, I can have another box doing the work that I've got loaded on
the router, but would like to keep it all in one.

Thanks
