Folks,

  After a painful, remote maintenance nightmare after a lighning
  strike and new hard disks were courier'ed to the school, I am
  nearly there but for one (major) problem.

  The network (35 clients) will not boot.

  I get this in the logs :-

Jul 21 20:47:12 eshigh dhcpd: 5 bad IP checksums seen in 5 packets
Jul 21 20:47:48 eshigh last message repeated 2 times

  I am not there - I am working on it with the school teacher
  who has difficulty typing "pppd call wizzy" and we communicate
  via a "ntalk" window.

  System :- 2 Thin Client servers, NFS-mounting home dirs off
  a "wizzy" box that handles all central services, like DHCP
  and TFTP and named and dialup.

  Dhcp version:  dhcp-3.0pl2-6.14

  So - the Servers are not involved at this time (booting) - that
  all comes off the "wizzy" box.

  Operating system: Whitebox Respin 1 - a RHEL clone.

  Packages as far as possible completely stock.

  Two 24 + 2 (GigE) port CNET switches, daisy-chained through
  the GigE links.

  GigE card, r8169, plugged into GigE port, new, untested.

  /etc/sysconfig/hwconf says this :-

class: NETWORK
bus: PCI
detached: 0
device: eth0
driver: r8169
desc: "Realtek|RTL-8169"
vendorId: 10ec
deviceId: 8169
subVendorId: 1371
subDeviceId: 434e
pciType: 1
pcibus:  0
pcidev:  a
pcifn:  0

  I can ssh in to other (local-boot) computers on the network -
  the two Thin Client servers, a print server, with no problems.

  Those servers successfully mount /home from this box.

  No firewall on the "wizzy" box.

  Google tells me nothing.

  Ideas, anybody ?

Cheers,   Andy!
