Testing multicast with iperf Raw. Gistfile1.txt this is a sample of output: root@percona-db-2: ~# iperf -s. Generating Multicast Traffic If you're a protocol junkie like me, you probably enjoy investigating a variety of network traffic types. Coreldraw x8 keygen torrent. I don't encounter multicast. I am looking for a good simple tool that runs on a standard OS (Windows or Linux) that I can used to test that multicast is being passed properly by a router. I have been asked by a client to enable multicast routing on a Linux box acting as their router since their to for a few features. Since I am not physically near the client I don't really have the ability to experiment with the various methods for setting up multicast routing on Linux. I can setup a router at my desk that is identical to what is deployed on their network, but I don't know of any good simple tools that I can use to generate or listen for multicast traffic. The one mulicast tool I have found is which is part of the Windows 2000/2003 resource kit. From what I have read online it seems that mcast.exe does not work across a router, and only works on the local network, so that doesn't seem to be useful for me to test multicast routing. So what do tool(s) do you use to test that multicast routing is properly setup? Don't have much real world multicast experience, but have you seen mz? Description: versatile packet creation and network traffic generation tool mausezahn (mz) is a fast traffic generator written in C which allows you to send nearly every possible and impossible packet. It is mainly used to test VoIP or multicast networks but also for security audits to check whether your systems are hardened enough for specific attacks. Mausezahn can be used for example:. * as traffic generator (e.g. To stress multicast networks); * to precisely measure jitter (delay variations) between two hosts (e.g. For VoIP-SLA verification); * as didactical tool during a datacom lecture or for lab exercises; * for penetration testing of firewalls and IDS; * for DoS attacks on networks (for audit purposes of course); * to find bugs in network software or appliances; * for reconnaissance attacks using ping sweeps and port scans; * to test network behaviour under strange circumstances (stress test, malformed packets.). Homepage: There's also ssmping: Description: check your multicast connectivity Tools to check whether you can receive Source Specific Multicast (SSM) or Any Source Multicast (ASM) via either IPv4 or IPv6. If a host runs ssmpingd, users on other hosts can use the ssmping client to test whether they can receive SSM from the host. Another program called asmping is also provided to check whether can receive ASM. Homepage: Both installable on Ubuntu 10.10. Iperf is perfect for this and it's readily available for most linux distributions and windows. On the listener side:% iperf -s -u -B 224.1.1.1 -i 1 ------------------------------------------------------------ Server listening on UDP port 5001 Binding to local address 224.1.1.1 Joining multicast group 224.1.1.1 Receiving 1470 byte datagrams UDP buffer size: 110 KByte (default) -----------------------------------------------------------.and it will wait to hear from the source. The Win7 firewall has an option about blocking IGMP inbound rules, new rule, Custom, choose Protocol, then choose IGMP. Outbound rules, new rule, ditto I see no such option in the XP firewall. It knows of ICMP but not IGMP.
