very intrigued by your solution Timo, have attempted something similar in the past to no avail. When I tried I was unable to retain the user at domain when setting the domain as extra field - protected is new to me and can't find documentation - but also doesn't work :( # cat passwd.domains 10.100.1.1:::::::domain:protected=foo.org 10.100.1.2:::::::domain:protected=bar.org # cat

Hi, I''m trying to set up 15 different delay intervals for packets leaving on an interface, using netems hanging off of a 16-band prio. I''m having trouble adding anything to bands higher than 10. Here''s what I tried: tc qdisc add dev eth0 root handle 1: prio bands 16 \ priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 I want all default traffic to go to

I''m trying to use tc and netem to delay packets from several different machines as they exit via eth0. Assume two source IPs, 10.0.0.122 and 10.0.0.133. I''d like to delay packets from the first one by 200ms, and packets from the second one by 300 ms. Any other traffic should be sent out normally. Here''s what I tried: # make three classes, 1:1, 1:2, and 1:3: tc qdisc add

Hi everybody, Just have myself added into the maillist. I have a few linux boxes with Kernel 2.6.9. Each box has 2 ethernet interfaces, one 3COM, one Intel. I connected one with Power Line Modem, and one with Wifi Modem. They form a nice network with bridge. I have a few questions here. Suppose I have two path from box A to box D, which path will packets go through? If I want to monitor the

TL;DR: Is there a way to force a bridge to forward anything and everything on all ports (except the ingress port) *regardles* of any permanent FDB entries (such as the MAC addresses of interfaces acting as bridge ports)? For context, I'm using a network-namespace (container) based simulator (think GNS3 or CORE), which allow me to run multiple FRR instances in their own dedicated netns,

I''m trying to build a wan latency test environment, where packets from different "remote" locations get delayed by different amounts of time, depending on which remote location we''re pretending they are from. Currently, I''m doing this using the ''prio'' qdisc to obtain multiple bands, and hanging a different netem qdisc off each of the branches

Hi all, Can anyone explain me why we need all this per port state information. A bridge port seems to be either in BR_STATE_LISTENING, BR_STATE_LEARNING or BR_STATE_FORWARDING. I don't get it, thought the bridge is learning from MAC addresses of the received packets, therefore while listening. Why a bridge port distinquishes these states? Thanx, Patrick

I've setup several bridges before using the code. Never had any problems. Recently I set Mandrake 10.0 up on a rackmount, with a builtin NIC and a 4 port ethernet card. Initially, I plugged 2 links

Hi, Is there any particular reason why the same physical port cannot be added to multiple bridges? Is it because of STP? If I am not using STP - can I change the code to have the same physical port in 2 VLANs? Is that a safe change? Thanks, Abhijit

Hello. I'm fairly (very) new to the kernel and networking in general, but I thought I'd give the following a shot here... I was reading thought the STP chapter in Understanding Linux Network Internals and testing out the bridging configuration with brctl, and was surprised to find that setportprio would only have any effect for values 0 to 63 (on 2.6.12.3 and using bridge-utils

Hi, I have a situation where in there are 2 switches A and B. port 0 of A is connected to port 0 of B port 1 of A is connected to port 1 of B all the four ports are in auto negotiation and 100mbps Last byte of MAC of A = 7F Last byte of MAC of B = 7E (remaining bytes of the MAC address are identical) Considering the switch B will be elected as root bridge which port of switch A will be root

Greetings, I'm just wondering how one can make the bridging tools stop spamming the virtual consoles? I would rather have all those "entering forwarding state", "entering learning state" and "entering disabled state" messages go to a log than have them plastered all over whichever console I happened to be logged into to work. Thanks! -- Martin-Eric Racine

if I just connect two similar port say both 10 gb of one switch to another = symmetric bridge with stp enabled on both bridge , stpstate of all four po= rts always remain forwarding. ( may be because all four of them are either root or desginated port in abo= ve setup) should I except that one port atleast will get into blocking state , if i c= onnect two non-similar ports together say a 10gb

Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

Hi, I am writing this email in sincere hope that somebody experienced similar/same problem and found solution to it. The classical bridge setup could be achieved using brctl tool, which could be found at: http://home.regit.org/br2684.html I have an ADSL CO line card Linux based [2.4.24 kernel] with 8 nas interfaces and eth0. Rather than having bridge, the decision was to have a router, which

Hi, I'm trying to allow domain-less logins for a multi-domain virtual IMAP server, and wondering if I can automatically infer the domain (value of variable %d) from the local IP (%l) or the hostname used by the client when connecting to my server. Let's say I have two host names: mail.foo.org (10.0.0.100) and mail.bar.com (10.0.0.200), with forward and reverse DNS configured to resolve A
