• Trixbox CentOS Default GW Problem (Multi-homed server)

  - by slashp

  I'm having an issue with a CentOS trixbox server which is dual-homed (one private facing NIC [eth1], one internet-facing NIC [eth0]). I can't seem to get the default gateway to set properly to our ISP's GW via eth0. I've modified the /etc/sysconfig/network to contain both a GATEWAY & GATEWAYDEV line and removed the GATEWAY line from /etc/sysconfig/network-scripts/ifcfg-eth1 (as well as /etc/sysconfig/network-scripts/ifcfg-eth0). No default GW shows up in the routing table unless it's specified in the ifcfg-eth1 file (which both the wrong interface and wrong gateway IP), otherwise, the routing table simply does not contain a default gateway..any ideas would be greatly appreciated! Thanks! EDIT Just realized when attempting to add the default gateway manually using the route add command, I receive an error stating: SIOCADDRT: Network is unreachable I know this error can occur when your default gateway and interface IP address are not on the same subnet..in this case, my public IP address of eth0 is a /29.

• Change user login in Windows 7 (after a misprint in username)

  - by Artem Russakovskii

  I have an install of Windows 7 that I've already put a few days into. Today I realized I've made a mistake in the username and it's driving me nuts (my personal OCD). While changing the physical folder name is perhaps possible, though quite involved, I do not want to open that can of worms. What I want to do is simply change the username I give when the login prompt shows up. I thought it's possible by just renaming the user account in the User Accounts but that didn't work. Is it possible to do then? Or is the only way to create another user and spend hour migrating everything I'd already customized to that user?

• Migrating an Active Directory domain controller to AWS

  - by Xavier Hutchinson

  I am required to migrate a Active Directory server into AWS with a couple other servers (SQL and IIS) to create a dev and test environment for our network / development. My plan at this time is to simply rebuild the Active Directory server in AWS from scratch - which is quite time consuming indeed! I was wondering if anyone had a recommendation as to a better and more efficient approach of migrating a copy of a physical Active Directory server to the cloud? The server is Windows Server 2012. Thank you!

• Why is Excel removing leading leading zeros when displaying CSV data?

  - by Velika Kudac

  I have a CSV text file with the following content: "Col1","Col2" "01",A "2",B "10", C When I open it up with Excel, it displays as shown here: Note that Cell 2A attempts to display "01" as a number without a leading 0. When I format rows 2 through 4 as "Text", it changes the display to ...but still the leading "0" is gone. Is there a way to open up a CSV file in XLS and be able to see all of the leading zeros in the file by flipping some option? I do not want to have to retype '01 in every cell that should have a leading zero. Furthermore, using a leading apostrophe necessitates that the changes be saved to a XLS format when CSV is desired. My goal is simply to use Excel to view the actual content of the file as text without Excel trying to do me any formatting favors.

• don't know how this virtual directory structure was setup on iis6

  - by deostroll

  Our development server has a setup as follows: \\DEVSRVR\WEBSITES\COMMON +---include Here is where all css and script files resides. They are required by various web applications \\DEVSRVR\WEBSITES\TESTING\SAM +---Backup ¦ +---bin +---bin +---help Here is where an application resides. Suppose there is an aspx page under the folder called SAM, we'd normally issue an http request as follows: http://testing.apps/sam/default.aspx We believe that testing.apps virtual name points to \\devsrvr\websites\testing folder. Suppose there is a css file called menu.css inside common/include. We'd simply have to make the following http call to get it: http://testing.apps/common/include/menu3.css This works!!! I don't understand how? There is no such folder called common inside of testing...

• Security measures for CentOS

  - by cappuccinodrinker

  I have been tightening up my web server security and wanted to know what else I can do. I am running CentOS 5 with these measures: - All passwords to FTP, MySQL etc are generated from grc.com/passwords.htm and microsoft.com/protect/fraud/passwords/create.aspx (for the ones which cannot be too long). - Running iptables with all ports shut off except for http mail and smtp, the important ports like FTP SSH are blocked to all except my static office IP. There is also no response to pings. - Rootkit Hunter running daily - The server is PCI compliant according to Comodo - Not running any crappy made php apps, we use Zend Framework for our stuff and do have kayako installed and keep them up to date. Can't really think of anything else I can do... I could implement a brute force measure, but I think I already have by simply changing my SSH port to a number above 10000 and blocking it off with iptables.

• Inserting new 'numbered item' on Word 2010

  - by MarceloRamires

  I have a very simple problem in Word 2010. I have a document with a Table of Contents, and I have the following items: 1. Title 1  [some text]   1.1 Title 1.1    [some text] I simply want to add an item 1.2. If I go at the end of Title 1.1 and press enter, an item 1.2 appears below it, but the text regarding item 1.1 stays below it all. I somehow used to be able to do it on word 2007, but I can't remember what I used to do, and before struggling in it for too long, I remembered SuperUser. Can someone answer this and maybe additionally link me to a tutorial on this ? Every one I find talks about having a text already numbered and adding a TOC in the beginning. I want to build the text all over the TOC.

WordPress created code: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /lobster-tail-blog/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /lobster-tail-blog/index.php [L] </IfModule> # END WordPress And even a simple thing like this throws the error: <IfModule mod_rewrite.c> RewriteEngine On </IfModule> Anyone know of any fixes or why this is causing this error? I have the mod_rewrite module loaded

• The canonical "blocking BitTorrent" question

  - by Aphex5

  How can one block, or severely slow down, BitTorrent and similar peer-to-peer (P2P) services on one's small home/office network? In searching Server Fault I wasn't able to find a question that served as a rallying point for the best technical ideas on this. The existing questions are all about specific situations, and the dominant answers are social/legal in nature. Those are valid approaches, but a purely technical discussion would be useful to a lot of people, I suspect. Let's assume that you don't have access to the machines on the network. With encryption use increasing in P2P traffic, it seems like stateful packet inspection is becoming a less workable solution. One idea that seems to make sense to me is simply throttling down heavy users by IP, regardless of what they're sending or receiving -- but it doesn't seem many routers support that functionality at the moment. What's your preferred method to throttle P2P/BitTorrent traffic? My apologies if this is a dupe.

• How can I refresh a document I have open in Excel in read-only mode?

  - by RoboShop

  I have an Excel document that is stored on a SharePoint Server, which I always have open on my computer in read-only mode because I need to refer to it. Every so often, in order to get the latest changes, I have to close down the file and reload it again. Are there any options within Excel 2007 which allow me to simply refresh a document I have open in read-only mode to the latest version on the server? Better still, is there a way where this could be done dynamically, without me having to hit refresh?

• How can I set Out-Of-Office in a shared mailbox

  - by balexandre

  I would want to set the out-of-office automatic response to all emails that arrive to our [email protected]. currently in the Outlook, I only have one mailbox (the user mailbox) but it has 2 shared mailboxes setup. I have tried to create a Rule that says: for all email received on account [email protected] forward to user [email protected] and make that user to set up the Out-of-office message, but it simply did not work, and I suspect that the rules only apply to the user account and not the shared account... How can I set Out-Of-Office in this shared mailbox ?

• How can I combine code from an old revision when I didn't branch in TortoiseMerge?

  - by gr33d

  I need to combine (merge?) some parts of an old revision with a newer revision of a file. I'm still pretty new to subversion, so I'm not sure what I'll bomb in the process. I did not branch--these are simply different revisions of a file. How do I send the sections of code from r1 to r3 where they are needed. The keyboard shortcuts and menu options for "theirs", "mine", "left block", "right block", etc aren't very intuitive. If I need 5 blocks from r1 to be after the first 10 blocks of r3, how do I do it? Shouldn't I be able to go through r1 block by block and decide if and where it belongs in r3? Thanks in advance!

• Browser extension (or other software) to delay page load

  - by Doug Harris

  The alt text to today's comic at xkcd.com (strip below) says: After years of trying, I broke this habit in a day by decoupling the action and the neurological reward. I set up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected. (bold is my emphasis) Does anybody know of a browser extension or other software that will add this sort of delay? I've seen extensions which simply block sites, but not a delay like this.

• Help with proposed iSCSI SAN VMware implementation.

  - by obsidian

  We have four (with plans to grow to four more) Dell servers with 6 NICs. They are running VMware ESXi 4.1. We would like to connect all of them to an Openfiler iSCSI SAN via HP ProCurve 1810G switches. Based on the design below, is there anything I should be concerned about or anything unusual that I should look out for when making the iSCSI network configurations on the servers, switches and OpenFiler? Should I bond the connections on the servers or simply setup them up for failover? The primary goal is to maximize IOPS. Thanks in advance.

• Microsoft Office 2011 Mac: Reminders don't interact correctly with Spaces or Expose

  - by abeger

  I'm using Microsoft Office 2011 on Snow Leopard. I'm a heavy Spaces user. Whenever Microsoft Office Reminders pops up a reminder, it brings up the reminder in my current screen. However, if I do something else before dismissing the reminder pop-up, I can't easily find the pop-up again: Clicking on the icon in the dock does nothing and the pop-up vanishes when you use Expose. Left with no other choice, I simply end up clicking through each screen, moving windows around to hunt down the pop-up again. Is there any easier way to locate that pop-up? Is there a way to get the pop-up to behave like a normal window?

• How to create a bootable Ubuntu Linux (10.04) USB installation for Macintosh

  - by vdavidovski

  I tried searching the Internet, but could not find a decent tutorial explaining how to create a bootable Ubuntu Linux (10.04) USB installation that could be run not only on a PC but also on Macs and MacBook Pros. In addition, I tried refit, but ended with "Missing operating system" error. Here is basically the layout of my bootable under PC Ubuntu USB drive (using MBR): Partition 1 (ext3, bootable) - Ubuntu Linux 32 bit, contains also grub2 bootloader. Partition 2 (ext3) - Ubuntu Linux 64 bit. Partition 3 (fat32) - contains data. What would be the best way to enable this drive to boot under Mac OS X? And if refit has to be used, could I simply have one more partition on the USB drive containing it? Thanks!

• VMWare Converter recommendations

  - by Tank Szuba

  I have two Ghost 14 backups of my machine. One for the machine fully configured with apps after and XP install and one of the last update before i re-imaged it (it's XP, I re-image about once every six months). I recently wanted to try simply using my initial image in a virtual environment to do my testing that generally causes me to need to re-image. I used the VMWare converter to convert the Ghost images to a virtual machine to use in Virtual box but they fail to properly boot. They get stuck after the bios loads and windows begins loading. If I power down the machine and refire it it will go to the error screen in windows that asks if you would like to boot to a different mode. none selected make any difference. What are some possible errors I should look for in the conversion process or in my settings for the converter?

• How can I use a computer as a router and send all client traffic through anonymous proxies?

  - by Terrapin

  Is there a way that I can setup a spare box as a router on my network, and route client traffic through a proxy in order to hide my location? Specifically, I would like internet traffic to/from my Roku Box to be routed via proxy, but there is no proxy support built in to the Roku. So I would like wire my Roku directly my computer's second NIC, and force all traffic through a proxy. What kind of software and hardware setup will I need? Also, which anonymous proxy service are best for this purpose? I'm not interesting in full anonymity or encryption. I simply want to mask my location while providing the best possible throughput.

• "Brute force attempt" on sending multiple emails

  - by bretddog

  While testing to send multiple emails, I successfully sent about 100 emails (with a 20KB pdf attachment), to the same email-address (my own), and they were all received. But on next attempt, my cPanel account was blocked, due to a "brute force attempt". Are there any special precautions I need to take when sending bulk emails? I simply looped through below code without pause for each email. What type of alert could that give on the email server, and how should I avoid it? client = New SmtpClient(smtp, Convert.ToInt32(port)) AddHandler client.SendCompleted, AddressOf OnAsyncSendComplete client.Credentials = New System.Net.NetworkCredential(usn, psw) client.SendAsync(mail, token) Should I wait for SendComplete event for each email before sending the next?

• AutoHotkey media button for the NextSong button on Pandora

  - by Christian

  I tried doing the same thing that had been advised to do on the Play/pause pandora.com with a media key answer page. I simply replaced the XXX with 119 after running GetMediaKey - instead of 122 (it was same for me), which worked just fine for its play/pause purpose. I also replaced the YY with 11 since it was the appropriate (and next) tab. It does put the small, orange, dotted square around the next song button, but instead of going to the next song, it just acts like play/pause. Is there another modification required? Using Google Chrome in Windows 7 on an Alienware m14x r2.

• How to Mirror or Clone a Spanned Volume in Windows 2008

  - by Matt

  I have a spanned volume (3x6+ TB disks spanned to one 20+ TB volume) that I need to mirror or clone to a new 20+ TB (unspanned) volume. Once mirrored or cloned I'm going to destroy the original volume and reuse the storage elsewhere. Windows 2008 will not allow me to mirror it because the original is a spanned volume. I cannot simply copy the data, because there are sparse files on the volume. So the OS thinks there is 150+ TB used on the disk when there really is only around 18TB used physically. When I try to use the copy command it won't run because it thinks the destination volume needs to be 150+ TB to hold it all. A conundrum, but I figure someone here has the answer. Thanks, Matt

• Postfix block senders outside from local domains

  - by Tibor Peter Toth

  I would like to block every mail that is coming in from a domain that is running on my server. Example: I have domain1.com on my mail server and I'm getting a mail from outside with an email address of [email protected] Then I know it's a Spam, because domain1.com is on my server, so the sender cannot come from outside. I want postfix to check for this, and simply block these kind of emails. I know this is a function in postfix, just don't know which one. Thanks.

• create replica of ext4 filesystem and re-use it

  - by Jatin

  Is there a way that I can use my Linux ext4 file system, as such and then use it on some other computer. I have a dual-boot of Windows 7 and Ubuntu 10.04 and my partition table looks like this: My question might not be clear, so explaining it with an example. Can I copy my Linux partition on a flash drive and then use it on a different PC, with or without any need to install Ubuntu on new PC, by simply booting from the copied ext4 partition. This way, I can easily port my Ubuntu packages and other applications, settings etc. from one PC to other. If it's a very stupid question, please don't mind.

• What's the shortest way to post a cropped screenshot on the web?

  - by Borek

  If I want to send someone a piece of my screen this is what I currently do: PrtScr or Alt+PrtScr Open Paint.NET Paste the screen shot Make a selection Crop image to selection Save image to some location - and remember it! Go to some image hosting site (there are plenty of them in the days of Twitter) Click their "Browse" button Browse for the image if I happened to remember the location where I stored it :) Upload the image and obtain the link which I can share This is simply too many steps. I don't usually mind doing steps 1 to 5 but especially steps 6 and 9 are annoying. Jing is pretty close to what I'm looking for but I find their horrible URLs unbearable. If there was something with similar functionality but better or pluggable hosting, that would be great.

• Restrict a port to a single app

  - by viraptor

  I'd like to restrict a range of udp ports to a single application (or a user). What I'd like to achieve is not simply blocking a bind() from other uids, but also remove the range from a pool that can be auto-assigned. For example, if someone tries to explicitly bind 12345, but doesn't run the specified app, they should get EPERM. If someone tries to bind an unspecified port, they should never try to bind 12345 at random. Is there any system that can help here? I tried browsing apparmor / selinux docs, but they seem to do the blocking part only.
