Suggestions on a Tutorial Draft
As per MsMittens suggestion here: http://www.antionline.com/showthread...hreadid=260815 I’m posting this draft of an upcoming tutorial here. Since the subject is so broad (Answers to common question about what you can find out with just an IP address) I know there will be a lot of comments/suggestions and there is a limited amount of time in which you can edit a tutorial. I’m trying to cover many basic questions that are asked all the time in forums but only take about a paragraph to explain. Suggestions are greatly appreciated. :
What can you find out from an IP?
Here I will outline some use full Unix and NT commands for finding out more information about a given IP. Some of these techniques will fail depending on firewall rule sets.
Topics:
How do I find my own IP?
How do I find out if an IP is contactable?
How do I find out what organization owns an IP?
How do I find out what OS a box is running?
How do I find out what ports are open/services are running?
How do I tell who is logged in to that box?
Any good all in one tools?
How Do I find the NetBIOS name from the IP?
How Do I find the IP from the NetBIOS name?
How do I find my own IP?
Because the IP your ISP's DHCP server hands you may not always be the same it is handy to be able to quickly find out what your IP is. Most of the time on a LAN the DHCP server will try to hand a machine the same IP it's MAC address received the last time it requested an address, but not always. To find out your host IP and other useful information use these commands.
Windows 9X/Me:
Use the "winipcfg" command, this will bring up a GUI dialog with all the info you will need.
Windows NT/2000/XP/etc:
Use the "ipconfig command.
Code:
C:\>ipconfig /all

Notice that this gives you allsorts of networking information, including your IP, Gateway, MAC Address, DNS server and Host Name.
Linux/Unix:
Use the "ifconfig" command to find the IP of the box.
Code:
bash-2.04$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:C0:F0:31:9F:10

bash-2.04$
If you are SSH/telneting to the box and you want to find the IP you are attaching from use the "finger" command with no parameters.
bash-2.04$ finger

To find you WAN IP (the IP the world sees when you are behind a NAT box or a Proxy) go to one of the following sites:
http://www.rootsecure.net/?p=your_ip
http://www.ipchicken.com/
http://www.whatismyip.com/
http://checkip.dyndns.org/
How do I find out if an IP is contactable?
If the host is not blocking ICMP echo requests (type 8, code 0) try using the "ping" command, it should work from any Unix like OS and from Windows.
UP:
Code:
C:\>ping 192.168.30.130

If the host is behind a firewall blocking ICMP echo requests then you will have to look into other ways of enumerating the network, like Hping ( http://www.hping.org/ )
How do I find out what organization owns an IP?
Easiest way is to use the online tools from http://samspade.org/t/ (use IP Whois) or download their Windows tools and use them on your box. Arwin offers a similar CGI at http://ws.arin.net/cgi-bin/whois.pl if Sam Spade does not work for you. There is also a host of tools built into the SamSpade utility for Windows, which you can download from http://www.samspade.org/ssw/ .
How do I find out what OS a box is running?
You can tell what OS a box is running in a few ways. Knowing what ports are open on the box will give you some good guesses (for instance port 6000 is used for X-windows, it being open probably means the box is running some kind of Unix). The easiest way to find this info is to use the "nmap" utility from http://www.insecure.org/nmap/ ( also available on the Knoppix Linux Boot CD ( http://www.knoppix.org/ ) or Trinux boot disk ( http://sourceforge.net/projects/trinux/ ) ) and do an OS fingerprint like so:
Code:
[root@tux adrian]# nmap -O tux.mydomains.edu
Starting nmap V. 2.54BETA26 ( www.insecure.org/nmap/ )
Adding open port 22/tcp
Adding open port 1024/tcp

Adding open port 110/tcp
Adding open port 993/tcp
Adding open port 6002/tcp

Notice the part in red indicate the likely OS. Be careful about using tools like "nmap", the site you are targeting may give your local admin a call asking why you are scanning their site. Also make sure your copy of Nmap is up to date so it has the newest OS fingerprints, the version I used in the above example is kind of old.
You can also find out sometimes by using the "What's that site running" cgi at Netcraft, which does a banner grab for you.
Telneting to the host and observing the intro may give you some info:
Code:
Red Hat Linux release 7.1 (Seawolf)
Kernel 2.4.2-2 on an i686
login:
and if they only have port 80 open you can telnet to that port and hit enter twice and observe the headers:
Code:
[root@tux adrian]# telnet orangutan.mydomains.edu 80
Trying 192.168.28.32...
Connected to orangutan.mydomains.edu.
Escape character is '^]'.
HTTP/1.1 400 Bad Request

Content-Type: text/html
Content-Length: 87
<html><head><title>Error</title></head><body>The parameter is incorrect. </body>
</html>Connection closed by foreign host.
[root@tux adrian]#
This technique is know as "banner grabbing".
How do I find out what ports are open/services are running?
There are port scanners for Windows and Unix, "nmap" ( http://www.insecure.org/nmap/ and available on the Trinux boot disk) being my personal choice. Be careful about using tools like "nmap", the site you are targeting may give your local admin a call asking why you are scanning their site. See the above entry for an example of using nmap.
If you want to find out what ports are open on your local Windows box use the "netstat" command.
Windows:
Code:
C:\>netstat

How do I tell who is logged into a remote Windows box?
On Windows you can try:
Code:
C:\>nbtstat -a somebox
Local Area Connection:
Node IpAddress: [192.168.22.68] Scope Id: []
NetBIOS Remote Machine Name Table
Name Type Status
---------------------------------------------
SE-SSCS-CV112C5<00> UNIQUE Registered
ADS <00> GROUP Registered
SE-SSCS-CV112C5<03> UNIQUE Registered
ADS <1E> GROUP Registered
JDOE <03> UNIQUE Registered
MAC Address = 00-04-76-39-A9-F9
C:\>
But if Netbios over TCP/IP it turned off it won't work.
In that case you may have to use a WMI script, but you would have to be an Admin on the remote box.
On Unix:
Code:
bash-2.05# nmblookup -S somebox
querying se-sscs-cv112c5 on 192.168.31.255
192.168.22.59 somebox <00>
Looking up status of 192.168.22.59
SE-SSCS-CV112C5 <00> - M <ACTIVE>
ADS <00> - <GROUP> M <ACTIVE>
SE-SSCS-CV112C5 <03> - M <ACTIVE>
ADS <1e> - <GROUP> M <ACTIVE>
JDOE <03> - M <ACTIVE>
bash-2.05#
The above will only work is the Windows box has Netbios over TCP/IP it turned on.
Any good all in one tools?
LANguard (for Windows) and Nessus (for Unix). With all these you would want to turn off some of the options, otherwise the admins at the other site will see is as an all out attack.
How Do I find the NetBIOS name from the IP?
On Windows:

Sugestions:
change "How do I find my own IP?" by " How do I find my own Internet IP"
"Time out" doesnt mean that target host is down. It just means that you cant have contact to it. I understood the idea but could pass the wrong idea. Ive seen most guys doing troubleshooting thinking "target out of service" instead "link is down"..
Other idea is break tutorial in several parts. Maybe its long as it is now. How about to group ideas and split on more tuts?

" How do I find my own Internet IP"
Umm.. IP means Internet Protocol. Perhaps it would be better to word it as How do I find my own IP Address

MsM,You got me. I should explain more.
He is talking about ISP assigned IP. Most of the ppl say that as "Internet address (or IP)".
Just to clarify that he isnt talking about in a generic way. Its a specific address,the public one
(public perhaps?)

It's an IP Address regardless of whether it comes from the ISP or comes from the Internal LAN. The distinction should be made on the difference between public addressing scheme and private addressing scheme. Irongeek, before going into IP Subnetting and the different between public and private (reserved) addressing, check to see if there are existing tutorials that you could reference instead. (avoids re-inventing the wheel as it were. )

Picky I know, but these just caught my eye.
Notice the part in red indicate the likely OS
You didn't add the color codes.
LANguard (for Windows) and Nessus (for Unix). With all these you would want to turn off some of the options, otherwise the admins at the other site will see is as an all out attack.
If you are going to reference the options available than you should give an example of the safest configuration. Or at least list the most dangerous options.
Also there were several small typos in the text. Other than those I found it to be a well written informative tut.

I forgot to adapt the HTML colors from my draft to VBBoard code. Feel free to mention any typos, I know there are plenty. I'll try to be more specific about IP addresses for WAN/LAN/Private/ETC.

For typo and spelling and/or grammer errors, I am probably the worst person in the world to ask.
I would contact meeeee via pm and ask her to proof read it for you. She proof read my web site for me and corrected me on several mistakes that by myself, I would never have caught.
