Hello I have two linux machines connected via 2 dsl lines (bonded) 192.168.0.1-eth0-dsl---2Mbit---dsl-eth0-192.168.0.2 ^-eth1-dsl---2Mbit---dsl-eth1-^ so the final figure is something like this: 192.168.0.1-bond0---4Mbit---bond0-192.168.0.2 I can only use arp monitoring for fail checking - if one dsl line fails - automatically use only the other one. I set up everything correctly (i

Hello I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the bandwidth. But I want the absolute maximum rate to be for example 5Mbit and not to exceed it. here is the script: $tc qdisc add dev ${NETIF} root handle 1 htb r2q 4 $tc class add dev ${NETIF} parent 1: classid 1:21 htb rate 5Mbit ceil 5Mbit $tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate 2Mbit ceil

Hi I want to block the IP traffic between any 2 hosts on a switched ethernet LAN. Will setting all the possible IP addresses on a linux machine in the LAN do the trick or there is another easier solution? -- Anton Glinkov network administrator _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO:

CentOS 7.5, and on one system, I'm getting: setroubleshoot: SELinux is preventing /usr/sbin/sendmail.sendmail from read access on the file disable_ipv6 ll -Z shows -rw-r--r--. root root system_u:object_r:sysctl_net_t:s0 /proc/sys/net/ipv6/conf/all/disable_ipv6 I find this peculiar. Anyone have a resolution, or is this a bug? mark

hi, I have very annoying problem.. First a simple diagram : x.x.1.0/24 -----------------| x.x.2.0/24 -----------------|---- (gw: eth0: x.x.1.1 eth1: x.x.2.1 eth1: x.x.3.1) ----> x.x.3.0/24 -----------------| now I have two machines x.x.3.10 (2.4 kernel) and x.x.3.11(2.6 kernel) AND they are in the same LAN (phisical net) but as u see in different IP (logical nets). As I look the traffic

Hi, If you are running brctl tool on the linux box then there is a command that will automatically determine the number of MAC addresses in the network #brctl showmacs <bridge name> <port number of ur lan interfce> grep -v -w port | wc -l Ex: #brctl showmacs abcd 1 grep -v -w port | wc -l Note that, for this to work your box should be confogurred as a bridge in promiscuous

It seems that the value of net.ipv4.ip_conntrack_max has no so much to do with the conntrack ''cause the when I measure current number of connections i.e.: wc -l /proc/net/ip_conntrack they show as ~20-30 000 connection, but I set sysctl -w net.ipv4.ip_conntrack_max=150000 and packets get dropped, I have to set it to value above 200 000 so that packets are not dropped ?!! Any idea

HI List, How do i reset the values in /proc/net/dev ? This file holds values for count of each (packet && byte), (sent && received) through all interfaces. I''m using a monitor which reads values from this file and prints out some nicely formatted output. But i need to reset the values. ie. set then to zero. Restarting the network does not do what i want. I guess a reboot

Hello, Currently I use following htb configuration: --------------- 1:0 ----------- / | \ 1:1 1:2 1:x / | \ / | \ / | \ 1:1001 1:2001 1:3001 1:1002 1:2002 1:3002 Classes like 1:1,1:2,1:3 limit my clients to some value, let''s say 128kbit/s. Classes like 1:1001 are

Hi We have applied the routing patches from http://www.ssi.bg/%7Eja/#routes. To 2.6.15 this seems to have broken our output natting. Has anyone else experienced this or any advice on how to fix. Is this working on the newer kernel i.e. 2.6.19 ? Any help would be appreciated. -- Tim Haak email: tim@haak.co.uk cel: 0837787100 First love is only a little foolishness and a lot of curiosity,

Hi, on page 3 of the lartc HOWTO one can read that it''s possible to do routing based on user id. Can someone explain me how to do this? And is it somehow possible to set the DSCP depending on the user id?

I''m sure that I had found (and printed out ...) a really good tutorial that explain how to use Julian Anastasov''s routing patch, but I can''t seem to find it now.
