Next Previous Contents 10. The cdrom nfs server side This section describes how to mount and export via NFS a cdrom drive. Mount the cdrom. If you encounter a problem with your cdrom drive, read the CDROM-HOWTO. I assume that the cdrom device is /dev/hdd but it could be /dev/sr0 or /dev/hdb etc. The mount point I choose is /cdrom but you can choose the one you want: $ mount -t iso9660 /dev/hdd /cdrom You have to set up nfs services. If something goes wrong, read the NFS-HOWTO Verify your kernel supports nfs: $ cat /proc/filesystems ext2 nodev proc nodev nfs nodev ncpfs nodev devpts iso9660 Verify your portmapper can handle mountd and nfs client requests: $ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100005 1 udp 655 mountd 100005 1 tcp 657 mountd 100003 2 udp 2049 nfs 100003 2 tcp 2049 nfs Lines with nfs or portmapper have to be there. NFS on tcp ? progress have been made ! Then, rerun portmap, mountd, nfs: $ /etc/rc.d/init.d/portmap.init stop Stopping INET services: portmap $ /etc/rc.d/init.d/portmap.init start Starting portmapper: portmap $ /etc/rc.d/init.d/nfs stop Shutting down NFS services: rpc.mountd rpc.nfsd $ /etc/rc.d/init.d/nfs start Starting NFS services: rpc.mountd rpc.nfsd /etc/rc.d/init.d/ is /sbin/init.d/ on SuSE Linux systems. I had a dream last nigth: LSB was respected. (LDB: Linux Standard Base) Then, try to mount it "locally" (via nfs) on the source box and clean the test: $ mkdir /tmp/nfstest $ mount -t nfs source:/cdrom /tmp/nfstest $ ls /tmp/nfstest/ README debian/ locatedb.3 tools/ TRANS.TBL ftp.netscape.com/ ls_lR.3 upgrade/ boot/ install/ realaudio/ $ echo great stuff ! $ umount /tmp/nfstest $ rmdir /tmp/nfstest Bad luck ? Read the NFS-HOWTO and /var/log/messages. Check the nfs server with those commands: $ rpcinfo -p Run portmap with the -v flag: $ portmap -v kill portmap, mountd, nfsd and rerun them in this order: portmap, mountd, nfsd. Take a rest, get more coffee. Read again the NFS-HOWTO and restart. Now, the exported cdrom drive nfs server is ready to work. Congratulations. Next Previous Contents
