If you don't specify -network, then 127.0.0.1 is treated as the address (or name) of a specific host. Since you are going to be mounting this via 127.0.0.1, that counts as a host address and everything works. If you do specify -network, then 127.0.0.1 is treated as a network number, and the default netmask would be 255.0.0.0. I don't know why that's not working, but (a) I always specify -mask whenever I use -network, and (b) I always ensure that the host portion of the network number is all zeros. So if I were to do it I would use: /home/astreib/work/new-site.org -ro -network 127.0.0.0 -mask 255.0.0.0 (I would use 255.0.0.0 as the mask simply because that's the mask the actual loopback interface is using, but I don't think it actually matters as far as /etc/exports is concerned -- if you want to use an unusual mask to allow access to a subset of a network then as far as I know you should be able to). Unless you are binding multiple addresses on your loopback interface, I would just use 127.0.0.1 without -network or -mask and be done with it. Why open up the mount to an entire network when you really just need to open it up to a single host (yourself)? This is what I do in a similar situation (serving both ftpd and httpd from the same directory): relevant line from /etc/exports: /nfs/archive/dist/OpenBSD -maproot=root -ro 127.0.0.1 relevant line from /etc/fstab: localhost:/nfs/archive/dist/OpenBSD /var/www/ftp/pub/OpenBSD nfs ro,nodev,nosuid 0 0 Works fine for me. -ken
