[mythtv-users] Struggling with Diskless clients on Ubuntu (probably OT)

[Ben Lancaster]

Hi list,

I've been trying to get diskless clients up and running on Ubuntu Lucid Lynx for the past couple of days, but have hit a bit of a brick wall. Here's the situation:  Using the "mythbuntu-diskless-server-standalone", I set up DHCP and created a mythbuntu image (ltsp-build-client --mythbuntu). The DHCP server works correctly and machines are able to load the kernel and start booting (vmlinuz and initrd.img), but hang as soon as the mythbuntu boot screen appears, the boot output shows:

udhcp[286]: Sending discover...
udhcp[286]: Seneding select for 192.168.1.24...
udhcp[286]: Lease of 192.168.1.25 obtained, lease time 43200
IP-Config: eth0 hardware address 00:0c:29:ca:04:4f mtu 1500 DHCP RARP

...and then just sits there.

/var/log/daemon.log from the server shows the following output during the boot process:

dhcpd: DHCPDISCOVER from 00:0c:29:ca:04:4f via eth0
dhcpd: DHCPOFFER on 192.168.1.25 to 00:0c:29:ca:04:4f via eth0

I can't see any NFS mount requests coming in (should there be any?)

Here's the contents of relevant config files:

# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure -v"
# -- end

# /etc/ltsp/dhcpd.conf

authoritative;

subnet 192.168.1.0 netmask 255.255.255.0 {
    range 192.168.1.20 192.168.1.250;
    option domain-name "benlancaster.co.uk";
    option domain-name-servers 192.168.1.254;
    option broadcast-address 192.168.1.255;

#    get-lease-hostnames true;
    option subnet-mask 255.255.255.0;
    option root-path "/opt/ltsp/i386";

    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";
    }
}
# --end 

# /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

default ltsp

label ltsp

append ro initrd=initrd.img quiet splash nbdport=2000
# --end

Thanks in advance.
