Hello, I have wrote some scripts to shape about 1000 workstations. My config: Pentium IV - 2GHz, 1Gb RAM, RedHat Enterprise Advanced Server 3, kernel 2.4.21-9.EL, iproute-2.4.7-11.30E.1 2 Gigabit Lan cards in bridge mode. I use htb.

hello, I have working htb system with about 1000 users. Until now I reload all rules at change, but it take too much time to apply. I cannot delete applyed filters. There is rules for one user: #!/bin/bash -v # Download shaper EX -> 2:20 /sbin/tc class add dev eth2 parent 2:20 classid 2:1775 htb rate 8000Kbit ceil 10000Kbit quantum 1514 /sbin/tc qdisc add dev eth2 parent 2:1775 sfq perturb

I''m rate limiting and prioritizing traffic upstream of a slow wan link using htb, classic wonder shaper type stuff. I''m using the following command for traffic that does not match any of my defined filters: tc qdisc add dev eth0 root handle 1: htb default 50 It appears that local, non-routable traffic like arps and igmp are being snared by this and end-up queued in the lowest

I have tested Devik''s tc (103592 bytes) and 2.6.8 which I compiled. Both return "RTNETLINK answers: Invalid argument". Stephen Hemminger should be sent a patch that fixes this. An example that returns the above error message is: tc filter add dev eth1 parent 1: protocol arp prio 5 u32 \ match u16 0x0806 0xffff at -2 flowid 1:50 I''m using this because it works:

Hi all. I experienced a strange behaviour in the "arp" command when I use the "pub" (publishing) flag. This is the scenario (I know it''s an unusual one, but it''s just for a test): __________ | | | host C | | | |__________| | __________|________________________________

Hello I'm trying to setup a bridged guest on an ubuntu 13.10 but it doesn't work. (Everything is ok with NAT) Network sniffing shows that arp replies don't come back to the guest. Test 1 ------ Guest : ping host_bridge_ip (ok) Test 2 ------ Guest: ping other_lan_host (KO) other_lan_host - receives arp who-is request - sends arp reply

Hi everyone. I have a problem with this command: @arp_table = `arp -n` When I execute it on console, all is perfect, but when I put it in the script on Rails the string arp_table is empty and I don''t view any result. If I do a script like that: @list = `ls -l` all works perfectly. Where is the mistake ? Thanks in advance -- Posted via http://www.ruby-forum.com/.

I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This
