After reinstall the file system, the following file should be checked.
/etc/hosts
  127.0.0.1  localhost
  170.140.39.1  gn600  loghost ----------IP address for gn600
  170.140.39.4  euch2e INDIGO ----------IP for other computer
      telnet euch2e or IP both work, if not in here, you        have to type IP for ftp and telnet.

/etc/rc.boot
  hostname=Omega #after reboot the hostname will changed to Omega,
     whenever
     #you can set the hostname by #hostname gn600 command.
/etc/netmasks
  170.140.39.0  255.255.255.62  ------chemistry department. Emory

/etc/networks
  loopback 127

#ifconfig le0 170.140.39.1 up
If all hardware work, it should work by using ping command
#ping 170.140.39.1
170.140.39.1 is alive #other IP# should have the same response.
