ssh -R limitations?
Hi there! I've a couple of questions on -R feature: Here is my situation: PC_A has a private IP, ssh client and has a service I want to see from the internet. PC_B is a linux firewall (public IP) where there is an open port that forwards all traffic to PC_C (ssh server on port 22) which is in PC_B LAN. I want to create a tunnel from PC_A to PC_C to access a service on PC_A from

Question: TEQL via gateway
Yesterday I posted a question, but I guess too much detail is provided that no one would bother to read, so I rephrase the question and hopefully some one may be willing to read. Sorry to spam. I am using TEQL on two computers, each with two network interfaces. The two eth0 are connected directly, and the two eth1 are connected via a gateway (a linux machine). The problem is that when I send

TEQL and Subnet problem
TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. My problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"), the traffic can never go from P2.eth1, and all traffic only goes to P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking for the MAC address of 16.119.144.66, although I have specified the route to

TEQL: 2 Mbit eth1 + 2Mbit eth2 = 1Mbit teql0
Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the

urgent TEQL problem
OK, I spammed the mailing list recently, but I will be fired if I can''t solve the problem today. (just kidding, but I did waste lots of time on it :( ) The common configuration for teql is for two computers connected directly with two links. My topology is a little different: one link is connected directly, but the other is connected through a gateway. My problem is teql can''t

IP Masquerade issues
Okay here is my setup: Gentoo Box running 2.6.4 w/ 4 NICs 1 NIC is for internal network 3 NICs are for external network The machine has a static address assigned to the internal network nic. This nic runs dhcp and dns forwarding. The other 3 nics have external dynamic IP addresses. All will have the same gateway. There are 3 NICs because this is a very large pipe, that will only allocate a

Teql and NetEm can''t work together
Thanks in advance! Summary: when I load netem and teql together, teql doesn''t work correctly. (If I load teql only, everything is fine) I loaded both netem and teql. Netem is associated with eth0, and teql is associated with both eth0 and eth1. But traffic only goes out of eth1. Attached are the commands that I used to configure teql and netem (on machine 1), and commands to

TEQL and Subnet problem (reformatted)
TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. P1, P2 and P3 are three linux machines, and each has two network cards. P2 and P3 are connected in two ways: (1) directed connection between P2.eth0 and P3.eth0; (2) connection via P1. P1 acts as the gateway. TEQL is installed on P2 and P3 to load-balance packet transmission by round-robin sending packets

QoS script for gw without NAT?
I''ll take it from the begining... About one year ago I only had 1 IP and used wondershaper. It worked great. Now I got /27 (32 IPs) and a gw computer that talks to two ISPs via a two tunnels. See: http://www.flashdance.cx/pics/flashdance-LAN.png I _really_ have a need to do QoS on my connection, for example I host websites that uses all available upstream. When I download at the same

HFSC Advanced Limiting
I am investigating changing our broadband bandwidth control scripts over to HFSC. What I would like to accomplish is this: { * DOWNLOAD * I need a download class for each user (we''ll call it Class 1) that offers a minimum of lets say 384Kbps and a maximum of 1.5Mbps. The rates between 384Kbps and 1.5Mbps should be shared among all users. Each user should always be able to get at

Egress shaping over multiple interfaces?
Hello, After reading the excellent HOWTO I got traffic shaping working nicely over ethernet devices on a test setup. I can''t put this setup live though, because our main firewall has three 2mbit hdlc interfaces instead of a single device. We are using multipath routing using iproute2 nexthop at the moment, and that works fine for firewalling. But now I have a need for shaping and

iptables CLASSIFY and MARK not working?
I have to match my packets based on MAC address, which I cannot do in the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this does not seem to work: wireless-r1 bwlimit # iptables -L -v -n -t mangle Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes) pkts bytes target prot opt in out source

teql on virtual network interfaces ?
Hi all, I want to implement a "weighted" teql that can send packets to interfaces based on their "weights". To do this, I want to create multiple virtual network interfaces, and add them to teql. Since teql will send packets to each interface in a round-robin way, a weighted teql is achieved (my guess). I already have two physical network interfaces, eth0 and eth1. I

cross-subnet browsing
I have 2 subnets. Subnet 1 has an NT WINS server. Subnet 2 has a Samba server acting as domain master browser and local master browser for a workgroup. If I view the network neighborhood from a Win 95 PC on Subnet 1 (call it PC_A), I can see all the hosts in the workgroup on both subnets. If I view the network neighborhood from a Win 95 PC on Subnet 2 (call it PC_B), I cannot see PC_A. I
