Re: IPv6 raw socket to send original udp
On Tue, 16 May 2006, JINMEI Tatuya / [ISO-2022-JP] ¿ÀÌÀãºÈ wrote: So, if a program needs to specify an arbitrary source IPv6 address for outgoing packets, it should use other "packet injection" interface such as BPF. One problem with using BPF for packet injection in IPv4 is that it requires the sender to provide the link layer encapsulation, make the routing decision, and perform any address resolution. Using raw sockets with the full header option allows the sender to generate a datagram from an arbitrary source yet not perform those routing and link layer activities, which require more intimate knowledge of the link type. It might be desirable to add a socket option to allow the specification of the source address in order to allow packet replay tools, etc, to work without link layer knowledge.

Cluster solution
Hi, I need help in designing of cluster solution based on FreeBSD. I tried carp for switching IP addresses, it seems to work ok. The solution is suitable for DNS, MTA, static web pages, web proxy and reverse proxy. I didn't find anything quite suitable for dynamic web pages with PHP and MySQL backend. I found just master and slave replication and clustering in MySQL. There could be problem if master fails with automatic promotion of slave to master and with the resynchronization of database after recovery of master database. Has anybody any experience with described setup. Howtos, pointers, links about configuration and software solutions are very appreciated. Thanks in advance.

We've built a setup for dynamic pages on CARP and mod_backhand (apache module). It doesn't scale to more than 50 application servers though. The shared storage is a big problem. All the well-known (?) SAN filesystems doesn't work on FreeBSD. We're testing FreeBSD NFS client for stability (see my thread on this list); NFS server doesn't seem to be ready for production use. We're going to purchase a clustered NetApp solution (now testing on Solaris as NFS server). You can apply a "circle" replication using standard MySQL features. This method is used in livejournal and officially admitted by MySQL AB; it doesn't provide scalability though. We're trying to make 2 "master + multiple slaves" hierarhies; the solution is not ready yet.
