Hi all,
I am trying to set up a system with a diskless client booting from a =
fbsd server with DHCP. After having read all docs and man pages I could =
find on this topic and googled all over the web, I and after having =
struggled for almost a week, I now humbly beg for some help.=20
I got so far as getting the client to boot from an etherboot disk, =
receiving its IP address, loading the kernel and booting it. After =
having recognized all hardware it simply freezes (after the line "acd0: =
CDROM etc").
Now, I am first of all not sure whether the problem is on the client or =
server side. I understand the kernel on the client is now supposed to =
look for a root file system on the server. But is it looking at all or =
has it just crashed? Shouldn't some error message appear if it cannot =
find the NFS stuff it looks for? Or will it just shut up and hang if it =
doesnt find it?
Here is my /etc/exports file:
/usr -alldirs
/data -alldirs -maproot=3D0 -network 192.168.0.0 -mask 255.255.255.0
The dir /data/misc/diskless contains the exported root dir (done with =
the script clone_root in /usr/share/examples/diskless). I fixed the two =
patches to that script and rc.diskless2 before running it).=20
Here is dhcpd.conf:
default-lease-time 600;
max-lease-time 7200;
ddns-update-style none;
authoritative;
option domain-name "visimedia.com";
option domain-name-servers 212.116.86.132;
option routers 192.168.0.1;
subnet 192.168.0.0 netmask 255.255.255.0 {
use-host-decl-names on;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.0.255;
}
host ganesh {
hardware ethernet 00:20:AF:4A:93:4B;
fixed-address 192.168.0.10;
next-server 192.168.0.1;
filename "/tftpboot/kernel";
option root-path "192.168.0.1:/data/misc/diskless";
}
I compiled a boot kernel with the BOOTP options and put it in /tftpboot =
and /data/misc/diskless. These are the only alterations it has from =
GENERIC:
options BOOTP
options BOOTP_NFSROOT
options BOOTP_NFSV3
options BOOTP_COMPAT
I also (not sure if this is needed) created the dir /conf/default/etc =
and did cp -Rp /etc to it.
Any help would be greatly appreciated.
Regards
Per Claesson
