• any security tips for my first server? (complete beginner)

  - by Haroldo

  I'm paying for a VPS and hoping to launch my first website on it in the next few days. I'm worried there might be some glaringly obvious security holes in the standard setup, so I'm keen to get some tips About the only thing i know is turn off error reporting in PHP and create users/privilages for MySQL... any more stuff along those lines? I'm using: cpanel and WHM centos 5 php mysql google apps as mail server (so maybe i should disable built in mailer server somehow?!!) This is my first post of Server Fault (i use stack overflow alot), I hope i'm posting this in the right place, with the right tags - please feel free to edit if i'm wrong. Thanks guys!

• What's the deal with NTFS tags in windows 7

  - by polarix

  So back in the days of 'longhorn' there was this WinFS idea which was both cool looking and scary looking. Then it seemed to disappear, but we were told that many of the concepts would be rolled into Vista. Then maybe Win7. Anyway, nowadays if you look at a win7 Explorer window, you can have columns that have a lot of tag-based info about a file (right click on column header-more...), including one called "tags". Is this something in NTFS that can be modified per-file somehow? Is its GUI hiding, or is this something that's infinitely-delayed, or is it just a figment of my imagination? Sure would be nice to be able to get around the NTFS path 256 character limit for searches, and to filter file folders per Excel 2007.

• snort-mysql not starting on Ubuntu server

  - by Rsaesha

  I am following this tutorial: https://help.ubuntu.com/community/SnortIDS I've set up the database, everything has installed correctly, and I've configured the snort.conf file so it outputs to a database (with creds all filled out ok). When I run /etc/init.d/snort start, it fails but does not produce any error message other than [fail]. The last few lines of /var/log/syslog are: snort[5687]: database: must enter database name in configuration file#012 snort[5687]: FATAL ERROR: My output database line in the snort.conf file is: output database: log, mysql, user=snort password=... dbname=snort host=localhost I have tried it with the commas separating everything, putting quotes around stuff, etc. The password is only made up of letters (after I thought maybe a number was throwing it off).

• Clean logging with BASH

  - by Matt Krouse

  I have a script that deletes files 7 days or older and then logs them to a folder. It logs and deletes everything correctly but when I open up the log file for viewing, its very sloppy. log=$HOME/Deleted/$(date) find $HOME/OldLogFiles/ -type f -mtime +7 -delete -print > "$log" The log file is difficult to read Example File Output: (when opened in notepad) /home/u0146121/OldLogFiles/file1.txt/home/u0146121/OldLogFiles/file2.txt/home/u0146121/OldLogFiles/file3.txt Is there anyway to log the file nicer and cleaner? Maybe with the Filename, date deleted, and how old it was? Any suggestions help!

• MP3 vs M4A (AAC): what is the audio codec for portable devices which gives maximum independence?

  - by akira

  A couple of years back MP3 was the most supported format for portable devices. Then Apple came along and wiped the floor of all the portable devices with the iPod as well as the iPhone. They clearly favour M4A (AAC). When to choose, right now, the 'best' audio codec to encode music to, which would you choose to achieve maximal independence of portable device vendors: MP3 or M4A? (I am well aware of Ogg (vorbis): no market (maybe this changes with HTML5 and more WebKit on portable devices), I am also aware of FLAC: I dont want to discuss long term storage.)

• Installing Color-Theme with GNU Emacs 23.2 on OS X Snow Leopard

  - by idclark

  Hi all, I've just started using emacs a week ago and I've been unsuccessful in installing color-theme using GNU Emacs 23.2 on OS X. With Ubuntu the whole process took maybe a few minutes with the package manager, but I'm completely at a loss with OS X, what the heck is a "tarball"? I don't have any experience compiling source code. I know Carbon Emacs comes with color-theme packaged, what would i lose by reverting to Emacs 22? I'd prefer staying with GNU Emacs 23 across both systems. Any input is greatly appreciated!!

• Setting up Amazon Cloudwatch to get an alert when you server is down

  - by Saif Bechan

  I have an instance running on Amazon EC2 that I turned into a webserver. Now I have been looking at cloudwatch, but I do not know if it is the correct tool for the job. Basically I want to get informed when the server is down, for whatever reason. Maybe the server got hacked, or the server shut down for whatever reason, I want to get a notification on that. I have enabled clouwatch, and tried to set up a alert, but I only see things like network in-out or cpu usage, an d metrix. Now I do not know if these will do the trick.

• Asus Eee replacement netbook monitor doesn't fit connector

  - by Michael Morisy

  I bought a replacement screen for an Asus Eee netbook 1005HA from a company that said the screen they were selling was compatible, but the connector on the replacement is smaller than the original. I've scoured the net for instructions, but so far, I'm out of luck. As far as I can tell, they both have 32 pins, but maybe I'm missing a connector? The replacement is a [LG Philips 10.1 inchs Glossy LED Panel Screen][1]. Picture of two connectors I couldn't include due to low rep. The replacement is on the left.

• Network Block Device (NBD) clients for Windows or similar solutions

  - by przemoc

  Are there any NBD clients for Windows? Strangely, I cannot find any, or I am searching for them in a wrong way. Such client should be possibly a driver with front-end tool (may be a command-line one) allowing to create virtual drives and associate them with given hosts (or simply localhost) and ports where NBD servers are listening. From user perspective virtual drive should be close to what physical drive is, so it should be accessible as something like \\.\PhysicalDriveX (maybe \\.\VirtualDriveX?), be visible in Disk Management (diskmgmt.msc) and mountvol tools at least. (The only thing I found remotely close to NBD on Windows is ImDisk's proxy mode and companion tool devio, but AFAIK ImDisk only works at partition level (so no virtual drive) and devio uses different protocol.) Secondary question is: Are there any (preferably simple) Windows-specific solutions allowing creation of virtual drive delegating read/write request to user-space via some explicit way (like via TCP, IPC, DLL implementing given API, etc.)?

• Connecting to iSCSI Target

  - by Joost Verdaasdonk

  I've installed Microsoft iSCSI Software Target 3.3 on a server 2008 R2 machine and created a new iSCSI Target. In the target I created a new Virtual Disk. From another server I started iSCSI Initiator and in Targets | Target I typed the IP of the Target. (Also tried DNS name.) But when I click Refresh I never see the target. Through googling I found this Youtube tut from a French guy doing pretty much what I did (only difference is I'm in a domain). I first though that maybe Port 3260 was closed but its not I can telnet to it. Also disabled all firewalls to see if that was blocking anything... No luck so far. Does anybody know of possible reasons why I can't connect to the iSCSI Target? If I can provide more info please let me know what's needed? Extra info: I've used this tut to set things up.

• Needing to concatenate between cells that change daily. I want to be able to automate this vs manual

  - by Harold

  I use concatenate to pull data together from different cells in my spreadsheet. Since my data changes daily, I want the formula to also change daily without having to manually input the new cell in the concatenate formula. I am looking for a way to do this but not sure how. Can anyone out there help me out please!? I appreciate the assistance in advance! Maybe this will help to explain what I need. I have a row of data from D4:AH4 that I insert daily based on the new day. When I use the concatenate and us the following formula: =CONCATENATE(TEXT('Raw Data'!B4,"m/d")," ",TEXT('Raw Data'!C4,"")," ",TEXT('Raw Data'!E4,"0.0%"))... E4 being the cell that changes daily where next day would be F4, G4, etc... All other parts of the formula will stay the same. I hope this helps! Thanks! :)

• Keyboard not responding during boot

  - by Peri

  My keyboard just stopped responding during boot. So I cannot go to BIOS or select system which I want to start. It is USB keyboard and it was working before. I borrowed PS2 keyboard and it also isn't working during boot. Lately I have been having problems with hard disk. Once every 2-5 minutes LED was on for 30 seconds and win7 wasn't responsive. I connected disk to another controller on motherboard and seems it is working now. All that suggests that to me that that motherboard is broken. What can I check? Or maybe you have some other suggestions?

• A way to auto cycle (close) through all screen sessions

  - by JBWhitmore

  I frequently use screen when I log into the interactive nodes to a supercomputer that I have access to -- and I often run things and move on. There are about 20 separate nodes that I can log into; and if I check any one of them I'll have something like 4 detached sessions. Each of those sessions will have maybe 5 screen sessions within that. Is there a quick way to cycle through all of these and close them down if they are not running any processes? My current process is to screen -ls and then screen -r #### then type exit until I'm back to the base screen.

• PHP Requests Being Blocked After Making About 25 in Ten Minutes

  - by Daniel Stern

  We have an administrative portal where we run PHP functions through a Javascript portal using ajax for administrative purposes. For example, we might have a function called updateAllDatabaseEntries() which would call AJAX functions in rapid succession, with those functions each executing numerous SQL queries. The problem is after making several successive requests from the same computer (not an excessive amount, maybe 30 in ten minutes) the system will stop responding to any PHP, HTTP requests ETC ONLY from my computer. From other computers in the office the panel can still be accessed, and access is restored to this computer after about 15 minutes. We believe this is not a glitch but some kind of security feature built into our server, possibly relating to Suhosin and likely well-intentioned but currently preventing us from running our system administration. Server Info: Linux 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux Cheers - DS

• On Windows 7, how to Shut Down the computer without the Update?

  - by Jian Lin

  Sometimes when my Win 7 machine has programs that crashed, maybe Firefox, or IE, I would like to shut down the computer without installing any Windows update. That's because I worry that if IE or Firefox crashed, the system is not in a very stable state, so I would rather install the update later. But it seems I only have 2 choices: 1) Shut Down and it always will do any Update 2) Restart, and no update is done (these are 2 choices among the shut down / log off option) So is there a way to Shut Down without doing the Update? Or must I restart first, and then do the Updates, and then Shut Down?

  Given the Network Configuration: Internet (121.243.x.y/27) | (121.243.x.z) Static : Public Global IP Modem Bridge Mode | WiMAX (192.168.1.1/24) +169.254.1.1/24 : Modem Configuration Page | (192.168.1.2) Router DLink DIR 615 | Ethernet + WiFi (192.168.0.1/24) | Local network (192.168.0.2) Workstation Ethernet | no WiFi Is there any way, maybe using Routing Tables, to access the Modem configuration page at 169.254.1.1 from my local network, using a Windows 7 PC? Note that the modem is currently able to display its configuration page at 169.254.1.1, i.e. even while it is in bridge mode.

• How can I insert the quoted price of gold from kitco.com into my excel spreadsheet?

  - by Frank Computer

  kitco.com provides a realtime price quote for gold and other metals. I have a spreadsheet which makes calculations based on the price of gold and would like for this realtime value to automatically be updated on my excel sheet. I tried 'get external data' from a website but that didn't work. any ideas? EDIT ADDED: Kitco has a gadget called KCAST which displays realtime quotes on the Windows taskbar. I tried capturing those values from the taskbar but that didn't work either. Maybe if Kitco provided an API or feed, it could be done?

• How to pull SNMP information from Windows commandline without installing software

  - by mkanet

  I would like to be able to quickly pull SNMP information via commandline such as device uptime. I noticed Net-SNMP's snmpget.exe can do this; but it looks like I need to install Net-SNMP first before I can use that executable. Isn't there any way to make this executable portable? When I simply copy it to another machine and try to execute it, it complains that netsnmp.dll is missing. If I copy that file to the same folder, it still says the file is missing. I even tried to regsvr32 that dll, but I was unsuccessful. Maybe there's a better way to get simple SNMP information from the Windows command line using royalty free/non-commercial software? Edit: It looks like I may be able to answer my own question. http://www.snmpsoft.com/freetools/snmpget.html "SNMPGet.exe"

• How to configure Time Machine to also backup an connected external hard drive?

  - by Another Registered User

  I've inserted a sweet SSD into my MacBook Pro, but it had limited space. So I had to export 60 GB of Data to an external hard drive. But now, when I run TimeMachine to backup my stuff, of course it only backups what's on the system disk. Is there a way how to also backup the connected external hard drive together with TimeMachine? Maybe there's a trick to get this work, with a fake folder that's actually the mounted drive? What could I do?

• Powershell Set-Acl fails

  - by Ulrich

  While working on a little backup script I try to change the ACL of a file using Set-Acl in Powershell 1 on Vista and always get the following error message: Set-Acl : The security identifier is not allowed to be the owner of this object. This error persists even if I go a minimal script: $acl = Get-Acl $sourcepath$file $acl |format-list Set-Acl -path $sourcepath$file -AclObject $acl Does anyone know the reason for this error? Obviously I'm not changing the ownership of the file... BTW: What I ultimately want to achieve is to reduce all access rights to ReadAndExecute. Is there maybe an easier way of doing this in Powershell? Thanks for your help! Ulrich

• Failover NIC with Windows 7 running Apache Server

  - by Benjamin Jones

  I have a Apache Server running on a Windows 7 Desktop for a internal website (Intranet). I am trying to figure out how I can make this system as failover safe as possible. One thing I want to do is use the 2nd NIC card that is currently disable. I only have one gateway address to my router. I do not have any computer running a Server O/S. If NIC1 crashes by chance(just humor me!), how could NIC2's IP take on the host name (I have mapped in host file) . I don't really care if the static IP of NIC2 changes seeing that the host name is the only thing I need. Could I add two IP's to the host file, with same host email and maybe create some script that will run IF NIC 1 fails? OR is there any failover software that will do this for me?

• IE 9 home page is hijacked by avg

  - by horace

  I definitely know how to change the home page in Internet Explorer (Tools -> Options -> General). The problem is, no matter what I put there, it never changes. Stop/restart Internet Explorer and the old home page is back. I did some research to see if there is a registry key that I could tweak to get the home page to set properly. I changed the start page registry key and refreshed the view and the start page key (without even restarting regedit) was reset back to its original value. Now I'm a little concerned. Maybe there's some virus I can't detect on my system? Internet Explorer 9.0.8112.16421 Windows 7 Pro SP 1 x64

• eCryptfs on ubuntu server : How to keep the home mounted without being over ssh?

  - by Bebeoix

  I have a daemon program who need to read in a file who is saved somewhere in my home folder. But every time I close my ssh connection, this daemon can't read the file because it appear that eCryptfs unmount the home. Maybe there is an option to force eCryptfs to not only mount with an ssh connection ? I didn't found it. Thanks. PS : I know this thread, http://askubuntu.com/questions/165608/why-is-ecryptfs-only-mounting-private-home-directory-over-ssh, but this is not the proper/good way to deal with the request.

• How to download big file with chrome on Mac OSX?

  - by Eye of Hell

  If I try to download a big file on unstable connection/server (XCode 4) Google chrome simply "stops" downloading on first network error so I have a first 1-2-3 gigabytes of file and chrome thinks that download is finished. Unfortunately, I need to download an entire file, so I need a more advanced download tool like a wget. But there comes a problem: most URL's currently on the web is not a direct URL but multiple "redicrect" pages that utilize complex javascript in order to generate next url and redirect browser to it. Chrome handles such things ok, but if I try to supply such URL to wget it will download some "intermediate" page as a file - not a file itself but an HTML page with complex redirect javascript. is it any way to get a direct URL from chrome or to somehow discover it so I can use it with wget? Maybe it's some avanced download manager integrated in chrome that I just need to install? I use MacOS X 10.6.6 and latest Google chrome.

• Route global shortcuts to pages opened in Firefox

  - by zamza

  I like listening to music online on sites like stereomood.com. There is a major problem, however. I can not control the player with my keyboard. And even with a mouse - when I want to play/pause I must activate firefox window, select the tab where music plays and hit play/pause button manually - this is a pain, especially when you play a fullscreen game that can not minimize itself. Thus said, global keyboard shortcuts would be a perfect solution. I understand that different online media players have different controls and each site must be configured individually (like, select button with id 'play' and press it), but I believe that can be done in principle. I also guess that such tricks are impossible without some third-party native app which captures shortcuts and routes them to Firefox window. So, any solutions? Maybe some AutoHotkey hacks or similar.
