Steve,
Setting up NFS should be straightforward. You install nfs-utils RPM,
set up an /etc/exports file, and do "service nfs start", that's it. Since
oscar set up the /etc/exports file for you, that step has been done. So,
install the nfs-utils RPM, start the service, and try again, I think that
should do it. Rich

Subject: Re: [Oscar-users] newbie question
Hi,
Yes, I'm root when I do all this (I haven't set up another user account
yet). I tried 'mount oscar:/tftpboot /mnt' and I still get a 'permission
denied' error. I'm pretty sure I don't have NFS set up right. I started
the service by running rpc.nfsd - I didn't edit any .conf files or anything
like I had to do to set up the dhcp daemon. I'll go dig around for info on
setting up NFS properly.
Yes, all the machines are using the same Intel motherboard and the eepro100
seems to be the right driver. Just for fun, I created the Etherboot
diskette using the eepro and tried booting and slave and it choked saying
it couldn't find the device. The boot diskette I created with the eepro100
finds the device and starts booting the system (complaining that it can't
find any Stallion cards, 3c59x, etc.) and just hangs when it says it can't
find an NFS server/daemon. I'll continue to give myself a crash course on
NFS.
Thanks,
Steve
