Hello, I was attempting to throttle egress traffic to a specific rate using a tbf. As a starting point I used an example from the LARTC howto, which goes: tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540 I then attempt a large fetch from another machine via wget (~40 megs) and the rate was clamped down to about 12Kbytes/s. As this seemed too much, I gradually increased

We upgraded all five servers to 1.2.4. We tried trunking/notrunking. End users use an IAX2 softphone on their desktop PCs. Agents are VLANed and all IAX2 traffic is QoS'd on all LAN and WAN legs. Calls flow from the agents to the local Asterisk server as IAX2/ulaw. Then they went over the IP-VPN as IAX2/g729 (we tried ilbc and straight ulaw as well). Calls get to the PSTN from the

>I can not even get IP anymore from my DHCP Hate to ask the obvious, but is the DHCP server on the same VLAN?

All switches and routers give highest priority to traffic on IAX2 port 4569. We use DSCB values over the IP-VPN to prioritize it as well. This did not change with the upgrade, as we can still see proper packet coding. The softphone is provided by our vendor Aheeva. It is the same IAX2 softphone they use in their own call centers. Funny thing is that they say that moving to Asterisk 1.2.4

If I could ask question about 10Gbit ethernet.... We have a 70 node cluster built on Centos 5.1, using NFS to mount user home areas. At the moment the network is a bottleneck, and it's going to get worse as we add another 112 CPUs in the form of two blade servers. To help things breath better, we are considering building three new NFS servers, and connecting these and the blade servers

Well FWbuilder is NOT easy. The documentation does not match the current GUI. Now the box is locked up. I will have to pull it again, hook it up to a kybd/VGA and reset iptables.... Maybe Shoreline with webmin.... Problem is I want a REAL router/firewall with little work. Both public and private nets have routable addresses. No NATing for me! I just help write the RFC ;) And all the
