Spoofed IP packets are still believed to be a significant problem for the Internet. But are they? The Spoofer Project is attempting to measure the problem. Apparently, 80% of the IP addresses measured no longer support spoofing! Their methodology is simple: have users download a client which attempts to spoof packets to the monitor. Using these packets, they can determine the filter rules. . The link for this article located at Slashdot.org is no longer available. . IP packet spoofing is the technique of sending packets from a false source address, used in malicious activities like DoS attacks and evading security.

The Trojan scans random ports on random machines, each time sending an initial SYN packet. One of the few identifiable characteristics of the program is a window size of 55808 on each of the packets it transmits. It also spoofs the originating IP address on all of the packets, making them look as if they're coming from machines in unallocated name space. ISS has been tracking the Trojan for about a month and has yet to find a copy of its code or successfully trace it back to an infected machine. Other security vendors and officials at the Department of Homeland Security are also tracking the Trojan, all without any luck so far.

Laurent Constantin let us know that the Lcrzoex Project now contains more than 300 GPLd network testing tools. "We are proud to announce that lcrzoex now contains over 300 network testing tools. Tool which passed this mark allows to spoof an IP/UDP packet.". . .. Laurent Constantin let us know that the Lcrzoex Project now contains more than 300 GPLd network testing tools. "We are proud to announce that lcrzoex now contains over 300 network testing tools. Tool which passed this mark allows to spoof an IP/UDP packet." Lcrzoex free toolbox is useful to test an Ethernet/IP network. As seen it permits to spoof packets, but also to: create UDP/TCP clients (to connect on a remote site) create UDP/TCP servers (to deliver local data) sniff (intercept network data) obtain information on computers' configuration ping, traceroute, scan replay data etc. Lcrzoex was adopted by hundreds of network administrators. It's available under the GNU GPL license, so each tool can be edited and recompiled to match one's needs. It was successfully installed on Linux, Windows, FreeBSD, OpenBSD and Solaris.
