This +information would be given to the kernel by "mountd" when the client +mounted the filesystem, or by "exportfs" at system startup. exportfs +would take information about active clients from /var/lib/nfs/rmtab. + +This approach is quite fragile as it depends on rmtab being correct +which is not always easy, particularly when trying to implement +fail-over. Even when the system is working well, rmtab suffers from +getting lots of old entries that never get removed. + +With 2.6 we have the option of having the kernel tell mountd when it +gets a request from an unknown host, and mountd can give appropriate +export information to the kernel. This removes the dependency on +rmtab and means that the kernel only needs to know about currently +active clients. + +To enable this new functionality, you need to: + + mount -t nfsd nfsd /proc/fs/nfs + +before running exportfs or mountd. It is recommended that all NFS +services be protected from the internet-at-large by a firewall where +that is possible. + Getting updated software ======================== @@ -368,6 +396,10 @@ ------------ o <ftp://ftp.isdn4linux.de/pub/isdn4linux/utils/isdn4k-utils.v3.1pre1.tar.gz> +NFS-utils +--------- +o <http://sourceforge.net/project/showfiles.php?group_id=14> + Netfilter --------- o <http://netfilter.filewatcher.org/iptables-1.2.tar.bz2> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
