Description of problem:
i was looking for a way to assign a host name to the machine.  i found i could
get to the Network Configuration GUI through "System Tools - Network Device
Control - Configure" or "System Settings - Network" and select the Hosts tab.

my home network has no DNS, but does have a Linksys DSL router with built-in
DHCP service, and the Linksys router assigns IP addresses.  as an experiment, i
had earlier added the LinkSys router fixed address under Hosts in the
configurator tool.  this time, "Hosts" shows that address listed twice.  i
deleted each, the configurator crashed, and a dump file was generated.  i opened
an Xterm window, and edited /etc/hosts to remove both references to the LinkSys
IP address.  i rebooted, reactivated the ethernet card, now everything is
restored.  

after the crash, SMB would start normally, but NMBD would not.  after the reboot
and reactivate, both SMB and NMBD appear to work normally.
