Determining the IP Address of a TFTP Server

Loading a firewall or PDM image requires you to use TFTP. Before using TFTP, you need to determine the IP address of the computer. When you get the information, write it down for use in the "Installing PDM on a firewall," section on downloading the PDM software.

Windows NT or Windows 2000

On a Windows workstation, click Start>Accessories>Command Prompt to launch the Windows command-line interface and then enter the ipconfig command as shown in the following example: 

C:\> ipconfig

Windows 2000 IP Configuration
 
Ethernet adapter Local Area Connection:
 
        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 209.165.200.225
        Subnet Mask . . . . . . . . . . . : 255.255.255.224
        Default Gateway . . . . . . . . . : 10.21.196.33
 
C:\>

In this example, the IP address is of the computer is 209.165.200.225 with a network mask of 255.255.255.224.

Windows 98 or Windows ME

From a Windows 98 or Windows ME computer, you can view the IP address by clicking Start>Run and entering the winipcfg command. Windows then displays a graphical user interface (GUI) listing the IP address information.

Sun Solaris

Enter the /sbin/ifconfig -a command to view the IP address, as shown in the following example: 

% /sbin/ifconfig -a

lo0: flags=849<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232
        inet 127.0.0.1 netmask ff000000 
hme0: flags=863<UP,BROADCAST,NOtrAILERS,RUNNING,MULTICAST> mtu 1500
        inet 209.165.200.225 netmask ffffffe0 broadcast 209.165.200.255

In this example, the IP address of the host is 209.165.200.225 with a netmask of 255.255.255.224. (ffffffe0 is the hexadecimal equivalent to 255.255.255.224.)

Linux

Enter the /sbin/ifconfig command to view the IP address, as shown in the following example: 

% /sbin/ifconfig"

eth0      Link encap:Ethernet  HWaddr 00:D0:B7:5D:C0:56
          inet addr:209.165.200.225 Bcast:209.165.200.255

          RX packets:75397725 errors:0 dropped:0 overruns:0 frame:0
          TX packets:75397725 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0

In this example, the IP address of the computer is 209.165.200.225 with a netmask of 255.255.255.224, as displayed in the example. The remainder of the display provides information on the status of data transmission through the computer.
