X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 22 Jul 2004 21:34:56 -0000 Hi, This is one of those obscure, yet well known issues in FreeBSD, some network stacks, like Linux, send the udp/icmp fragment first (if multiple frags -- in reverse order), then the orginal packet with the header. In -current, we still cannot process this simple fragged icmp-echo request from a Linux host. For example, 'ping -c 1 -s 1500 '. FreeBSD discards the frag(s) and when it sees the initial packet with header waits for the frags. So two questions: 1. is there a gnats pr? I tried various searches with no success. 2. are there workarounds/patches? -- othermark atkin901 at nospam dot yahoo dot com (!wired)?(coffee++):(wired);
