• How to limit server to specific IP addresses with mod_authz_host?

  - by BeeDog

  Hi! I am very new to this area, so please bear with me. :) Right now I am running an Apache HTTP server on my setup, a very basic configuration. The website hosted on it is accessible from anywhere, and I want to limit the access to a specific IP address range. I've looked into this and I found that one Apache module called mod_authz_host handles this. http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html The problem is, I haven't managed to find documentation that explains well how to actually do the stuff. How do I actually make sure only a certain range of IP addresses can access my site/server? The machine is running Ubuntu Server 10.10, the web files are stored in /var/www/, the apache2 daemon has its stuff stored in /etc/apache2/ and /usr/lib/apache2/modules/*. Thanks in advance, and sorry if this is a stupid question!

• How to migrate Notepad++ settings?

  - by NoCatharsis

  I am trying to portabilize every program I use if possible, and Notepad++ is on the list. The only problem is that I've had a native installation until now so that I'm not totally sure which settings files need to be moved to the portable directory. Surely there's a function tucked away somewhere in NPP exactly for this purpose, or some plugin out there? I mean the developers have literally thought of everything else, yet this is the one thing I cannot find specifically anywhere in the NPP wiki or otherwise, and I don't want to miss an important file. Here is the closest I've gotten: Notepad++'s configuration files and Where are all the files? Should I just copy every configuration file listed on the first link?

• Troubles doing transparent proxy for virtual machines

  - by Dan H

  Hi iptables gurus. First here is the basic topology: Internet | Gateway | Workstation---eth0---virbr0 | +-----+-----+ | | | vm1 vm2 vm3 I need to test a traffic analyzer running on my workstation, listening on some port (say 8990) on eth0. The rule [I think] I want is "any packets leaving virbr0 going anywhere to port 80 must instead go to port 8990 on eth0". My software running on port 8990 does its own check of the NAT packet mangling to push the packets through after it inspects them. I've been banging my head on this, with different variants of: iptables -t nat -A PREROUTING -i virbr0 -p tcp --dport 80 -j DNAT \ --to 10.0.0.10:8990 And I've tried the more generic method of using the mangle table with --set-mark and ip rule add fwmark, but I'm not getting it. I guess what's confusing me is that everything runs on the same box. Thanks for any guidance.

• Under *nix, how can I find a string within a file within a directory ?

  - by roberto

  Hi all. I'm using ubuntu linux, and I use bash from with a terminal emulator every day for many tasks. I would like to know how to find a string or a substring within a file that is within a particular directory. If I was knew the file which contained my target substring, I would just cat the file and pipe it through grep, thus: cat file | grep mysubstring But in this case, the pesky substring could be anywhere within a known directory. How do I hunt down my substring ?

• Disk Cleanup on Server 2008 R2 is ineffective

  - by cparker4486

  I have a user profile with ~2.9GB of Error Reports backed up in the ReportQueue folder (C:\Users\UserName\AppData\Local\Microsoft\Windows\WER\ReportQueue). Running DiskCleanup as the administrator does not detect these files and therefore does not clean them up. However, running the utility as the user shows an even larger amount (12.4GB!) of error reporting files. As seen below: The problem is that after running the cleanup utility the disk spaced used does not decrease by anywhere near 12.4GB and running the utility again detects the same 12.4GB of files. What is the problem here? Alternatively, can I manually delete the files in the ReportQueue folder?

• Nested/multiple brace-matching in Notepad++

  - by Melodic

  In Notepad++, is it possible to force all (or at least the 3 or 4 deepest) pairs of braces/brackets/parens/etc. that enclose the cursor to become highlighted? Preferably in different colors for each matched pair? For instance, in this example: int main(char** args) { if(blah) { ... } } If we place the cursor anywhere in the if-block, the main function's opening and closing braces should become one color, while the if-block's braces become another. The coloring for each block should stay the same as long the cursor is still in that block.

• Why my combobox count is 0?

  - by just_name

  Why the count of items in my ComboBox is always 0 although the datasource of this combobox has data !! <div align="right" dir="rtl"> <asp:Label ID="lbl_contactListName" runat="server" Text="Menu Name :" CssClass="span"></asp:Label> <telerik:RadComboBox ID="ddl_contactList" runat="server" AutoPostBack="True" CausesValidation="False" CollapseDelay="0" Culture="ar-EG" ExpandDelay="0" Filter="StartsWith" ItemsPerRequest="10" MarkFirstMatch="true" Skin="Outlook" EnableAutomaticLoadOnDemand="True" EmptyMessage="-New Menu-" ShowMoreResultsBox="True" OnSelectedIndexChanged="ddl_contactList_SelectedIndexChanged" EnableVirtualScrolling="True" DataTextField="list_desc" DataValueField="list_code" DataSourceID="ObjectDataSource1" EnableViewState="true" Width="300px"> </telerik:RadComboBox> </div> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetContactListsByDep" TypeName="SendSMS_EmailModule.ContactList"> <SelectParameters> <asp:SessionParameter Name="year" SessionField="year" Type="Int32" /> <asp:SessionParameter Name="main_code" SessionField="main_code" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource>

• Help recovering lost text from a refreshed Chrome webpage (it was in the clipboard as well)? [closed]

  - by tobeannounced

  Possible Duplicate: Chrome: where is the location to save browse temporary files Ok, so here's what happened - and yes, it was pretty stupid by me: I wrote up and submitted a post on Stack Overflow It was not suited to be placed on Stack Overflow as someone pointed out to me, so I deleted the post (this was a few hours ago) I copied the text into a new question page on Super User, but didn't submit it yet I accidentally just refreshed the webpage that had the text, and the question has now been deleted from Stack Overflow I have Lazarus installed, however the Chrome version doesn't have many features and the text was not recoverable from there. I do not have a clipboard manager, but the text was copied to my clipboard - so is there any way to get this back (Windows 7)? Although the post on Stack Overflow was deleted, I suppose it would have existed in my cache - could I recover it from there? Would the post on Stack Overflow exist in an rss feed anywhere? Many thanks, and I hope I can find this - and I am sure that the solution will prove valuable for me (and others) in the not too distant future once again.

• SQL Server database constantly restarting

  - by Michael Itzoe

  We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

• Sending mail via Exchange, why am I being flagged as spam?

  - by Dan

  Exchange 2007 uses direct DNS for all outgoing mail. Mail that is sent from our public IP (1.2.3.4 - this is the IP of my mailserver) is delivered to the spam folders for providers such as Comcast and yahoo. Currently, our SPF looks like this: v=spf1 ip4:1.2.3.4 mx a:mail.domain.com ?all MX: mail.domain.com.(10) The reverse DNS entry on our ISP is mail.domain.com for our IP The banner HELO response from our server is <220 mail.domain.com Our IP address is NOT blacklisted anywhere, and the Cisco Senderbase gives us a score of Good What is the reason our mail doesn't look legit?

• Redirecting HTTP traffic from a local server on the web

  - by MrJackV

  Here is the situation: I have a webserver (let's call it C1) that is running an apache/php server and it is port forwarded so that I can access it anywhere. However there is another computer within the webserver LAN that has a apache server too (let's call it C2). I cannot change the port forwarding nor I can change the apache server (a.k.a. install custom modules). My question is: is there a way to access C2 within a directory of C1? (e.g. going to www.website.org/random_dir will allow me to browse the root of C2 apache server.) I am trying to change as little as possible of the config/other (e.g. activating modules etc.) Is there a possible solution? Thanks in advance.

• Windows 7 Start Menu Items Missing

  - by PeteT

  If I click the start menu - All Programs almost all my installed programs seem to be missing from the start menu despite some of them being on the initial regulalry used screen. As far as I can see this has happened within the last week possibly after windows updates installed. Does anyone else have this issue? Anyone know a fix? I have looked in all the locations I can think of for start menu items and can't see them anywhere so it does actually look like they have been removed. I tried as system restore that didn't work.

• PHP errors not being displayed

  - by Mike

  I'm using PHP with Apache on Ubuntu 12.10. Errors are not being displayed to the browser for some reason and I can't figure it out. I have the following in my php.ini file: error_reporting = E_ALL & ~E_DEPRECATED display_errors = On display_startup_errors = On log_errors = On I am also positive that I have edited the correct ini file by verifying it with php_ini_loaded_file(). I can also verify that the values are correctly set by doing the following in my script: echo ini_get("display_errors"); // Outputs 1 echo ini_get("display_startup_errors"); // Outputs 1 echo ini_get("log_errors"); // Outputs 1 echo ini_get("error_reporting"); // Outputs -1 I have tried what seems like every possible combination of these settings (and restarting Apache after each change) and it is just not outputting errors. I am also not using ini_set anywhere in the script. It is being set only from the ini file. Any ideas why errors aren't being displayed?

• What is the network address (x.x.x.0) used for?

  - by Shtééf

  It appears to be common practice to not use the first address in a subnet, that is the IP 192.168.0.0/24, or a more exotic example would be 172.20.20.64/29. The ipcalc tool I frequently use follows the same practice: $ ipcalc -n -b 172.20.20.64/29 Address: 172.20.20.64 Netmask: 255.255.255.248 = 29 Wildcard: 0.0.0.7 => Network: 172.20.20.64/29 HostMin: 172.20.20.65 HostMax: 172.20.20.70 Broadcast: 172.20.20.71 Hosts/Net: 6 Class B, Private Internet But why is that HostMin is not simply 64 in this case? The 64 address is a valid address, right? And whatever the answer, does the same apply to IPv6? Perhaps slightly related: it also appears possible to use a TCP port 0 and an UDP port 0. Are these valid or used anywhere?

• Can I filter multiple column headers to display subheadings of each in Excel?

  - by Gigi

  I can't seem to find this anywhere... it may not even be possible without coding? I have a spreadsheet containing more than one heading in a single column. These headings are identified with blue background and white font. Each of these headings have items listed below them. These "subheadings" are smaller, auto-black font and no fill background. Currently I have to scroll down the spreadsheet to view all headers and their contents. How do I create a filter that would allow me to sort on whichever header I want, so that (only) the contents of that particular header are displayed?

• Hyperlinks in Windows Update window not working?!

  - by w3d

  The actual links in the Windows Update window to open the relevant knowledge base article have stopped working. They still look like links, but they just don't do anything anymore?! This started happening (or not happening!) during the last Windows Update (around 2010-10-23). At the time I believe the first link worked OK and all subsequent links did not!? In the recent Windows Update (today) no links work. I can copy and paste the text of the link into the browser and OK. Web-like links from all other applications work OK. Dec 2010 - Windows Update links still do not work. I guess this must be something specific to my machine as I've not seen it reported anywhere else?!

• How to host my own cloud so that videos are viewable via desktop web browser?

  - by jake9115

  I want to host my own cloud storage solution, something like Dropbox but entirely dependent on my own central machine. This way things are more secure if setup correctly, and there are artificial storage limitations or pay-walls. Some thing similar to ownCloud: http://owncloud.org/ There is one important feature I want to have: the ability the stream movies in a web browser from my personal cloud to anywhere in the world. In the past I tried this with a NAS, and I mapped XBMC to the NAS via SFTP, and certain media types could stream in this manner. I've also used things like PLEX. In this case, I am looking for a single solution for personal cloud storage and movie streaming from that cloud into a web browser. Does anyone know if this can be accomplished? Thanks for the suggestions!

• Why does ^M represent a carriage return?

  - by dotancohen

  Why is ^M used to represent a carriage return in VIM and other contexts? My guess is that M is the 13th letter of the Latin alphabet and a carriage return is \x0D or decimal 13. Is this the reason? Is this representation documented anywhere? EDIT: I notice that Tab is represented by ^I, which is the ninth letter of the Latin alphabet. Conversely, Tab is \x09 or decimal 9, which supports my theory stated above. However, where might this be documented as fact?

• Equalizer for Toshiba Satellite Pro Laptop (Windows 7) (has Realtek sound)

  - by Need Help

  Hi, I've been trying to find a way to have a real equalizer for my Toshiba Satellite Pro Laptop. I don't know much about computers but the guys in the store seem to know less than I do! From what I've been able to glean through friends, Windows 7 no longer supports a real equalizer function with Realtek, and the result is a fake "equalizer" that does nothing. I have hearing issues so not being able properly adjust the higher frequencies is causing me physical pain and ringing in my ears. I've tried to decipher the threads I find online but am quite confused by them. Basically I need an equalizer that will work with Windows 7 (with everything, internet, skype, music, etc). The current drivers offered by Realtek do nothing except make the sound inaudible. The one that may possibly work and provide an actual equalizer is a few versions back and can't be found anywhere. Thanks! And sorry if this is a duplicate question but I am confused a bit by the threads online.

• How can I get command prompt to merge my files in name order?

  - by Anastasia

  I'm using the copy command in command prompt to merge all the files in a directory, for a number of directories. The problem is, I need to edit the first file in each directory before I merge. This means that when I put in the command "copy /b *.mp3 name.mp3", the joined file has part 2 at the start and part 1 at the end, presumably because it was created last. Is there a way of using the copy command so that the files merge in name order? Each folder has a different number of parts, anywhere from 2 to 1000 so I don't want to list each file with a "+" in between. Ideally, I'd like to find something to insert into the copy command I'm already using. Otherwise, is there a way of rearranging the files in a folder so that if you enter "DIR", part 1 shows up first even if it was edited last? I'm using Windows 7 by the way.

• Stream computer screen to TV via network instead of a USB wireless link

  - by user24559

  I want to stream my computer screen (not just video or a limited amount of content) to my TV via the network. I know there are wireless devices that use USB to tranfer the screen to the TV. However, these are limited to a short distance. What I want to do is stream the data via the network so I can be anywhere within the network and have the data shown on the tv. I am looking for video and sound to transfer. I want the entire computer screen to transfer just like when you connect the computer to the tv via VGA or HDMI and the sound out using the 3.5mm plug. I have been unable to find a unit that allows for the entire computer screen to transfer via the network. I just find the ability to stream video. I am using Windows 7 Ultimate with a quad processor and 16 GB of memory so I have the power to handle the transfer. My tv is hdtv.

• Where to run Java and PHP code continuously

  - by az1112

  I'm sorry if this is the wrong forum for a question like this, but you have to start asking questions somewhere to get anywhere :) The question is pretty simple: I need a server where I can run Java and PHP scripts 24 hours a day, 7 days a week. I need to be able to access this server via SSH, and I need to be able to retrieve the data generated by scripts using SCP. Also, I need to be able to run 10-20 scripts simultaneously. What is the name of the thing I should be looking for? Is it a dedicated server? I'm confused for 2 reasons: 1) because there seem to be all kinds of servers out there; 2) because most companies advertising dedicated servers seem to be aiming them at people who want to host websites. But I don't want to host a website; I just want to run my code.

• How can I enable encryption for SQLite3 in PHP5.3?

  - by meouw

  The php manual for SQLite3::open has this information: public bool SQLite3::open ( string $filename [, int $flags = SQLITE3_OPEN_READWRITE | SQLITE3_OPEN_CREATE [, string $encryption_key ]] ) Opens an SQLite 3 Database. If the build includes encryption, then it will attempt to use the key. I would like to use encrypted SQLite databases for a project I'm working on, but I can't find any information anywhere on how to build the SQLite module including encryption. Does anyone know how to do this? Perhaps it's so obvious no one has published any information or perhaps only commercial modules are available. I've noticed that the developers of SQLite offer a proprietary encryption extension. Is this the only way to go?

• Change ip route metric

  - by notphunny

  I'm constantly switching between eth0 and wlan0 interface on my archlinux because I often change OpenWrt fw images on my second router (which isn't connected anywhere). So I have problem with my routes when I'm connected to my wlan and want to connect with Ethernet to my router. Both routers are on 192.168.1.1/24 and after connecting to my Ethernet profile eth0 route becomes default one (which is ok for the time), because of smaller metric I guess. So I'm interested, how can I change routes metric so my applications can be connected to the internet (through out wlan)? Maybe there is solution not to use Default Gateway on Ethernet profile, however I still want to know how to change metric. Or default route if there are more then one.
