Once we set up the proper filters for VXLAN and IPv6 (above), we can capture on our new capture0 interface using the command: sudo tcpdump -i capture0 -w awscapture0.pcap. Working with 80 of the top US news sites and global media sites in 50 countries, Chartbeat brings together editors and advertisers to identify in real time the active time an audience consumes articles, videos, paid content, and display advertising. Since tcpdump is installed by default on Amazon Linux, it’s great for capturing what was being sent within the AWS cloud to the mirror destination. If you explain the big picture, particularly why you feel you need for multiple addresses and what you intend to do with them, people may be able to offer better advice. 2 TCP/NGINX Tuning on EC2 Who are we Chartbeat measures and monetizes attention on the web. The interface addresses having a route on lo0 is perfectly normal and has nothing to do with outgoing traffic from those addresses. With PF, you can use route-to and reply-to options (and not bother with FIBs). With IPFW, you can match the source address and add a setfib action.
With any firewall config (including no firewall), using multiple FIBs (routing tables) can enable per-process routing using setfib(1) (or FIB-aware code can even do it per socket). Exactly how you do it depends on exactly what you are doing with those addresses and what type of firewall you use. You have to implement what Cisco would call "policy routing", or similar. If you need the outgoing packets to route via a different interface based on their source address, that can't be done with a single traditional routing table, as it strictly routes based on destination address. In this example we are using Ubuntu 8.10 however, the installation steps are similar for other Linux distributions. Inet 172.30.0.139 netmask 0xffffff00 broadcast 172.30.0.255 An important feature of tcpdump is a filter that allows you to display only the packets you want to see. The number of packages included in the RPMS repo in Photon OS 3.0 increased significantly, compared to 1.0.
