Hey, Scripting Guy! I have a script that uses Netsh.exe to return information from my DHCP servers; all that information is then written to a text file. That works great, except that I need to be able to parse the data and pull out any IP addresses included in that information.

How can I write a script that extracts just the IP addresses from a text file? -- MJ Hey, MJ. You know, a lot of people are mystified as to why we Scripting Guys do a daily scripting column. “Doesn’t that become a big hassle to have to write a new column every day?” they ask. “Isn’t it hard to come up with new ideas and new things to write about?

Wouldn’t it be easier to be a slacker like Scripting Guy Jean Ross, and just write rather than one new column a day?” Well, needless to say, the answer to all those questions is, “Yes.” Yes, it is a hassle; yes, it is hard to come up with new ideas and new things to write about; and yes, we would like to be like Scripting Guy Jean Ross. (Hey, who wouldn’t?) So then why do we continue to write a new Hey, Scripting Guy! each and every day? Well, that’s partly due to our desire to best Scripting Guy Jean Ross at every turn.

(Yo, Jean Ross, check the score: Hey, Scripting Guy! 781 columns, Sesame Script a measly 26 columns!) More importantly, however, publishing a new column each and every day gives us a chance to address your questions and concerns when it comes to system administration scripting.

Not to mention the fact that it also gives us a venue for shamelessly promoting everything the Scripting Guys do. You know, things like traveling to Barcelona, Spain for the , which modestly bills itself as: “Microsoft’s premier European conference designed to provide IT professionals with technical training, information and community resources to build, plan, deploy and manage the secure connected enterprise using Microsoft infrastructure products and technologies.” They’ve got us convinced.

As you might expect, the Scripting Guys are looking forward to the trip: this marks the first time we’ve ever been let out of the country to attend a conference. (Of course, whether or not they’ll let us back into the country has yet to be determined.) Scripting Guys Jean Ross and Greg Stemp will be manning a booth in the Ask the Experts section of the convention center; Greg will be there each and every day, Jean will probably show you up once and call it good.

( Ed itor’s Note: At least Jean will show up, which is .) Will we be available to chat and to answer questions? Of course we will. Will we be giving away hundreds of copies of , as well as a whole bunch of ? Of course we will. Will we let you throw darts at a big huge dartboard? Greg says yes we will; Jean says – well, never mind. We’re not allowed to print the things that Jean says any time Greg comes up with a new idea.

Anyway, if you haven’t for the TechEd IT Forum there’s still plenty of time to do so. And if you won’t register for yourself, then do it for the Scripting Guys. After all, we have no desire to explain to our manager why he spent all that money to send us to Barcelona only to have no else show up. Besides, the scripting world owes us one. After all, aren’t we the ones who showed you all how to write a script that can extract IP addresses from a text file?

Oh, we didn’t show you a script like that? Well, now we have: Const ForReading = 1 Set objFSO = CreateObject("Scripting.FileSystemObject") Set objFile = objFSO.OpenTextFile("C:\Scripts\Test.txt", ForReading) strSearchString = objFile.ReadAll objFile.Close Set objRegEx = CreateObject("VBScript.RegExp") objRegEx.Global = True objRegEx.Pattern = "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" Set colMatches = objRegEx.Execute(strSearchString) If colMatches.Count > 0 Then For Each strMatch in colMatches Wscript.Echo strMatch.Value Next End If Before we launch into an explanation of how the script works we should give you a peek at MJ’s text file.

That file, which uses data retrieved (and formatted) by Netsh.exe, looks a little something like this: ========================================================================== Scope Address - Subnet Mask - State -Scope Name -Comment - - Active -New York, Class C - New York, NY C Total No. of Scopes = 1 As you can see, we have two IP addresses in this file: and

Note. OK, technically, is the subnet mask, you may or may not want your script to return this value. The script we just showed you returns the subnet mask.

What if you don’t want the script to return the subnet mask? Relax; we’ll show you how to do that in just a minute or so. But first things first. The script starts out by defining a constant named ForReading and setting the value to 1; we’ll use this constant when we open the text file. After defining the constant, we create an instance of the Scripting.FileSystemObject, then use the OpenTextFile method to open the file C:\Scripts\Test.txt for reading: Set objFile = objFSO.OpenTextFile("C:\Scripts\Test.txt", ForReading) As soon as the file is open, we use the ReadAll method to read in the entire contents of that file and store that information in a variable named strSearchString: strSearchString = objFile.ReadAll And then we simply call the Close method to close the file.

At that point, we’re done. Well, OK, we’re done with the text file; when it comes to extracting IP addresses, however, well, there we still have a little bit of work to do. But that’s all right; the Scripting Guys have never shied away from a little hard work. Note.

Not that we’ve ever actually done any hard work, mind you. We’ve just never shied away from it. As MJ noted in his email, these IP addresses could be just about anything; there’s no guarantee that they all start with, say, 192.168. Does that complicate the issue of locating these IP addresses? Believe it or not, it doesn’t. At least not if you use regular expressions in your script. We’re not going to discuss the theory of regular expressions today; for that, you might check out the webcast , presented by the late, great Dean Tsaltas.

Note. OK, technically Dean isn’t really dead; he just moved to Canada. But that’s pretty much the same thing, right? At any rate, in order to use regular expressions within our script we first need to create an instance of the VBScript.RegExp object: Set objRegEx = CreateObject("VBScript.RegExp") As soon as we create the object we then set the Global property to True; that tells the regular expressions object that we want to search for all the IP addresses in our search string.

(If we didn’t set this to True the script would stop after finding the first IP address. Needless to say, that would be a problem if the file actually contains multiple IP addresses.) That brings us to this line of code: objRegEx.Pattern = "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" As it turns out, the Pattern property represents the value that we’re looking for.

(In this case, an IP address.) We’ll explain what that cryptic-looking pattern means in just a second. Before we do that, however, let’s take a few minutes to meditate on the nature of IP addresses. What is an IP address? Well, in general, an IP address consists of: • Anywhere from 1 to 3 digits (the values 0 through 9) followed by a period (e.g., 192.) • Anywhere from 1 to 3 digits followed by a second period (e.g., 168.) • Anywhere from 1 to 3 digits followed by one more period (e.g., 120.) • Anywhere from 1 to 3 digits (e.g., 1) Believe it or not, that’s an awfully good description of our search pattern as well.

The construction \d{1,3} means “Find some digits; there must be at least one digit ( 1) but no more than three digits ( 3).” The construction \. Means “Find a dot.” If you follow the pattern all the way through, what search criteria do we end up with? You got it: 1 to 3 digits (the values 0 through 9) followed by a period, then 1 to 3 digits followed by a second period, then 1 to 3 digits followed by one more period, then 1 to 3 final digits.

Crazy, huh? But it all works. After we define the search pattern our next step is to call the Execute method and perform a regular expressions search on the file contents; that’s what we do here: Set colMatches = objRegEx.Execute(strSearchString) If the Execute method finds any text matching the search pattern, that matching text will be stored in a collection named colMatches.

That means we can determine whether or not any IP addresses appear in the file simply by checking to see if the collection’s Count property is greater than 0: If colMatches.Count > 0 Then If the Count property is greater than 0 then we set up a For Each loop to loop through all the items in that collection.

Inside that loop we do nothing more complicated than echo back the match Value (that is, the text that met the search pattern): Wscript.Echo strMatch.Value What do we get back when we run this script against MJ’s sample dataset? This is what we get back: Don’t want the subnet mask to be included?

That’s fine; just add an If Then statement to your For Each loop and filter out any IP addresses that begin with 255. That’s something you can do by using the Left function to determine whether or not the first three characters in the value are equal to 255: For Each strMatch in colMatches If Left(strMatch.Value, 3) "255" Then Wscript.Echo strMatch.Value End If Next Run this modified script and you’ll get back the following: Bye-bye subnet mask.

And hello, Barcelona. If you’re planning on attending the IT Forum in Barcelona (November 12-16) and let us know (and be sure to pop by the Ask the Experts section and say hi.

Oh, and if you know of any good restaurants or any fun things to do in Barcelona we’d appreciate hearing about those as well. After all, even Scripting Guy Jean Ross has to eat. Well, once a month, anyway. When I copy and paste the script above, I get the following error: Missing expression after ','. At C:randomtest.ps1:4 char:57 + Set objFile = objFSO.OpenTextFile("C:ScriptsTest.txt", <<<< ForReading) + CategoryInfo : ParserError: (,:String) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : MissingExpressionAfterToken It doesn't matter what text file I point to….

what am I missing here? A little background: I am trying to grab an IP address from a log file. This is a large file with lots of events, most of which don't contain an IP address. The events that do contain "ip=x.x.x.x" (except with a real IP address ;-). What is the best way for me to search for that and then grab only the IP address itself? The regex I was thinking is: ip[=]d{1,3}.d{1,3}.d{1,3}.d{1,3}

Available Languages: | | | This document attempts to explain exactly what Apache HTTP Server does when deciding what virtual host to serve a request from. Most users should read about to decide which type they want to use, then read more about or virtualhosts, and then see .

If you want to understand all the details, then you can come back to this page. There is a main server which consists of all the definitions appearing outside of sections. There are virtual servers, called vhosts, which are defined by sections. Each VirtualHost directive includes one or more addresses and optional ports. Hostnames can be used in place of IP addresses in a virtual host definition, but they are resolved at startup and if any name resolutions fail, those virtual host definitions are ignored.

This is, therefore, not recommended. The address can be specified as *, which will match a request if no other vhost has the explicit address on which the request was received. The address appearing in the VirtualHost directive can have an optional port.

If the port is unspecified, it is treated as a wildcard port, which can also be indicated explicitly using *. The wildcard port matches any port.

(Port numbers specified in the VirtualHost directive do not influence what port numbers Apache will listen on, they only control which VirtualHost will be selected to handle a request. Use the directive to control the addresses and ports on which the server listens.) Collectively the entire set of addresses (including multiple results from DNS lookups) are called the vhost's address set.

Apache automatically discriminates on the basis of the HTTP Host header supplied by the client whenever the most specific match for an IP address and port combination is listed in multiple virtual hosts. The directive may appear anywhere within the definition of a server. However, each appearance overrides the previous appearance (within that server). If no ServerName is specified, the server attempts to deduce it from the server's IP address. The first name-based vhost in the configuration file for a given IP:port pair is significant because it is used for all requests received on that address and port for which no other vhost for that IP:port pair has a matching ServerName or ServerAlias.

It is also used for all SSL connections if the server does not support . The complete list of names in the VirtualHost directive are treated just like a (non wildcard) ServerAlias (but are not overridden by any ServerAlias statement).

For every vhost various default values are set. In particular: • If a vhost has no , , , , , , or directive then the respective value is inherited from the main server. (That is, inherited from whatever the final setting of that value is in the main server.) • The "lookup defaults" that define the default directory permissions for a vhost are merged with those of the main server.

This includes any per-directory configuration information for any module. • The per-server configs for each module from the main server are merged into the vhost server. Essentially, the main server is treated as "defaults" or a "base" on which to build each vhost. But the positioning of these main server definitions in the config file is largely irrelevant -- the entire config of the main server has been parsed when this final merging occurs. So even if a main server definition appears after a vhost definition it might affect the vhost definition.

If the main server has no ServerName at this point, then the hostname of the machine that is running on is used instead. We will call the main server address set those IP addresses returned by a DNS lookup on the ServerName of the main server. For any undefined ServerName fields, a name-based vhost defaults to the address given first in the VirtualHost statement defining the vhost.

Any vhost that includes the magic _default_ wildcard is given the same ServerName as the main server. The server determines which vhost to use for a request as follows: When the connection is first received on some address and port, the server looks for all the VirtualHost definitions that have the same IP address and port.

If there are no exact matches for the address and port, then wildcard ( *) matches are considered. If no matches are found, the request is served by the main server. If there are VirtualHost definitions for the IP address, the next step is to decide if we have to deal with an IP-based or a name-based vhost. If there is exactly one VirtualHost directive listing the IP address and port combination that was determined to be the best match, no further actions are performed and the request is served from the matching vhost.

If there are multiple VirtualHost directives listing the IP address and port combination that was determined to be the best match, the "list" in the remaining steps refers to the list of vhosts that matched, in the order they were in the configuration file.

If the connection is using SSL, the server supports , and the SSL client handshake includes the TLS extension with the requested hostname, then that hostname is used below just like the Host: header would be used on a non-SSL connection. Otherwise, the first name-based vhost whose address matched is used for SSL connections.

This is significant because the vhost determines which certificate the server will use for the connection. If the request contains a Host: header field, the list is searched for the first vhost with a matching ServerName or ServerAlias, and the request is served from that vhost. A Host: header field can contain a port number, but Apache always ignores it and matches against the real port to which the client sent the request.

The first vhost in the config file with the specified IP address has the highest priority and catches any request to an unknown server name, or a request without a Host: header field (such as a HTTP/1.0 request). The IP lookup described above is only done once for a particular TCP/IP session while the name lookup is done on every request during a KeepAlive/persistent connection. In other words, a client may request pages from different name-based vhosts during a single persistent connection.

If the URI from the request is an absolute URI, and its hostname and port match the main server or one of the configured virtual hosts and match the address and port to which the client sent the request, then the scheme/hostname/port prefix is stripped off and the remaining relative URI is served by the corresponding main server or virtual host. If it does not match, then the URI remains untouched and the request is taken to be a proxy request. • Name-based virtual hosting is a process applied after the server has selected the best matching IP-based virtual host.

• If you don't care what IP address the client has connected to, use a "*" as the address of every virtual host, and name-based virtual hosting is applied across all configured virtual hosts. • ServerName and ServerAlias checks are never performed for an IP-based vhost. • Only the ordering of name-based vhosts for a specific address set is significant. The one name-based vhosts that comes first in the configuration file has the highest priority for its corresponding address set. • Any port in the Host: header field is never used during the matching process.

Apache always uses the real port to which the client sent the request. • If two vhosts have an address in common, those common addresses act as name-based virtual hosts implicitly.

This is new behavior as of 2.3.11. • The main server is only used to serve a request if the IP address and port number to which the client connected does not match any vhost (including a * vhost). In other words, the main server only catches a request for an unspecified address/port combination (unless there is a _default_ vhost which matches that port).

• You should never specify DNS names in VirtualHost directives because it will force your server to rely on DNS to boot. Furthermore it poses a security threat if you do not control the DNS for all the domains listed. There's available on this and the next two topics. • ServerName should always be set for each vhost. Otherwise a DNS lookup is required for each vhost. In addition to the tips on the page, here are some further tips: • Place all main server definitions before any VirtualHost definitions.

(This is to aid the readability of the configuration -- the post-config merging process makes it non-obvious that definitions mixed in around virtual hosts might affect all virtual hosts.)

Computers do not actually know how to load a website without the IP address. So even though you may tell it, it must first ask the DNS (usually your router, or ISP) what's IP address it. Once the DNS Server respond with the IP address, your computer will negotiate a connection to the website.

If the webserver accepts, it will begin sending your computer the page. Your computer then parses the HTML or other website code, and displays the website for you. If your DNS server is down, this can cause some things (games, Instant messengers) to work fine, but webpages not to. Open a console and use 'nslookup' to find out the name of a given IP address.
