OpenBSD NFS

Skeletor configuration NFS configuration file is /etc/exports. There are many options that you can use in your /etc/exports file, and it is best that you read the exports(5) man page. Assuming the network is 10.0.0.0, we have an /etc/exports that looks like this: CODE # NFS exports Database # See exports(5) for more information.  Be very careful, misconfiguration # of this file can result in your filesystems being readable by the world. /mda -alldirs -ro -network=10.0.0 -mask=255.255.255.0 This means that the local filesystem /mda will be made available via NFS. -alldirs specifies that clients will be able to mount at any point under the /mda mount point. -ro specifies that it will only be allowed to be mounted read-only. The last two arguments specify that only clients within the 10.0.0.0 network using a netmask of 255.255.255.0 will be authorized to mount this filesystem. This is important for some servers that are accessible by different networks. portmap(8) must be running for NFS to operate. Portmap is off by default on OpenBSD 3.2 and later, so you must add the line CODE portmap=YES to rc.conf.local(8) and reboot. Next, you should add the line CODE nfs_server=YES to /etc/rc.conf.local. This will bring up both nfsd(8) and mountd(8) when you reboot. Beastman configuration You should add this code to your /etc/fstab CODE 10.0.0.1:/mda /mnt nfs ro 0 0 or, if dns or /etc/hosts are configured properly, CODE skeletor:/mda /mnt nfs ro 0 0 I hope, you as an experienced user, know what to do with it? Such things as mounting it all without reboot should be common to you - just start the server manually with CODE /sbin/nfsd -tun 4 echo -n >/var/db/mountdtab /sbin/mountd And mount with CODE mount -o ro -t nfs skeletor:/mda /mnt To restart the server, run CODE kill -HUP `cat /var/run/mountd.pid` Run this to see stats CODE rpcinfo -p 10.0.0.1
