I have this problem: I have an Internet line input with variable speed. I have a max speed and a min speed: Vmax and Vmin. The speed is always changing between Vmax and Vmin. I want to share the actual bandwidth (you don''t not how much, you only know the speed is between Vmax and Vmin) for N clients. The bandwidth should be shared so nobody can get more bandwidth than the others.

Dear Lists, I have problem regarding multipath connection to internet behind NAT. I use 2.4.26 kernel in RH-9.0 with Julian Anastasov patch, and version iproute2-ss020116 (Fedora RPM package). Dual homing and dead gateway detection work fine as we expected, the problem is , everytime we hit site that have redirect page address (URL no absolute), it''s doesn''t reply. (ex:

Did anyone see the article? It''s the first time I really noticed that these little Linksys routers are such a fully fledged linux machine with a decent processor and a replacable firmware. I am now itching to get one to replace the multipurpose firewall desktop machine. Has anyone experimented with the current state of the firmware and how advanced you can get with tc rules? For

I can use DSMARK to mark on the Egress side. Is there a way to mark/change the DSCP value of an incoming packet on the ingress side? Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Yes, last night it was 4Mbps the rate of incoming mails. I was wondering if I apply HTB to the following scheme: router -> gw-iface -> MX-server If HTB (new verb) the interface that communicates with MX, say, 2mbit, what will occur to the Input queue of gw-router-iface? Will I still get the link full for 4mbit or will it get lower to 2mbit too, as the inner interface? Appreciate

Hi, I would like to make a QoS configuration on a linux based dsl router. It is for a server, so I want to shape outgoing traffic, incoming traffic should not be a problem as long as I have a quite assymetric connection. I would like to achieve the following goals: 1) To have one class (p2p) having all the available bandwith if there is no activity on other classes. 2) If another class (ftp

I have long included tinc in the cerowrt project as a lighter weight, meshy alternative to conventional vpns. I sat down a few days ago to think about how to make vpn connections work better through fq_codel, and decided I should maybe hack on a vpn to do the job. So I picked up tinc's source code for the first time, got it working on IPv6 as a switch in a matter of minutes between two

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

Hello, Normally, in addition to such qdisc scheduler mechanisms as FIFO, PQ, WRR, WFQ, are there any more? Then, there is a confusion on scheduler in Linux enviroment: Assume there is a qdisc, such as RED as a leaf qdisc in a router, we know, if there is packet which want to enqueue the packet, the Function red_enqueue is called, but when the packet leave the queue(when the Function red_dequeue

OK, I''m stumped. I''ve read through most of the LARTC HOWTO and have yet to find a basis for what I need to accomplish. I have a Linux box that controls access to and from the Internet at my workplace. We have a number of remote employees that connect via PPTP and IPSEC to the office''s internal network. Some of these remote employees are currently using SIP phones.

Hello, I have been using shorewall for a long time now. I find it a great piece of software and I am looking forward to the IPv6 version that Tom is planning to start working on. I do however have a problem now that I do not seem to be able to solve. On my firewall system I have a Fedora Core 2 installation with Shorewall (2.0.13) running fine with kernel 2.6.6-1.435.2.3. When I however use a new

Sambaserver is not accessible I have a problem connecting to SAMBA from Windows/ME systems (using samba--2.2.2 on Red hat Linux 7.1) What I would like to know is - What can I change to get this to work properly? SETUP I have a simple network - three Windows/ME systems and 1 Red Hat Linux 7.1 system all on the same subnet. There is a linksys router on the same subnet that provides WAN

Hi Michal, What I found was that when I restarted the machine and did a virsh edit command to see the xml config, I see that it is was not actually changed. This suggests why I saw 256 again after restarting. So now I tried again to edit the xml via virsh edit command and used the following to set the parameters. <driver name='qemu' txmode='iothread' ioeventfd='on'

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

Hi, does someone have setup IMQ succesfully on kernel 2.4.20? If so, how did you do that. I only see the diff for kernel 2.4.19. Can I use that?

Dear Users/Developers, I am using a KVM Ubuntu VM as a degrader to apply specific delays to incoming packets. As the delay for my packets can be higher than 7.5 seconds, there is not enough buffer on my interface to buffer all the packets. Therefore those overflowing packets are dropped in the machine and not forwarded. When I tried to use the command ethtool -G ens8 rx 512 to increase the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I''m using HTB to shape my outgoing traffic over a ADSL-link with PPPoE with a nominal bandwidth of 128kbit/s. My goal is to favour small packets like ACKs and interactive services like ssh; in other words, I want to achieve low lantency. If there are some big packets going over the wire, everything works fine. But if there are
