• Why my internal hard disk can be ejected?

  - by Bear Bear

  I have 6 hard disks in my computer and one DVD. The disk that I connect to the 6th SATA port is a regular disk. But my Windows 7 64 bit shows it as a removable drive. I can eject my hard disk! Just like a pen drive. If I connect another disk to the 6th port, I can eject that disk too. So it has nothing to do with the physical disk, it must be something related to Windows or BIOS I don't understand why Windows 7 is seeing a normal hard disk as removable. In Computer Management - Disk Management, the disk looks identical to the others - there is nothing there to suggest the drive is different from the others. But in the tray I have the icon to eject it. The motherboard model is ASUS F2A85 V PRO FM2. All the disks are formatted normally, no Dynamic Disk, no RAID, nothing special. How can I tell Windows 7 to treat the disk exactly like the others, so it can't be ejected?

• CDN Rerouting on 404 (file not yet in synch with original storage)

  - by Alan Ristic

  Here is the problem. I've setup my app(on EC2) to store uploaded images directly on Amazon S3. I'd like to be able to serve static files(cdn) from my 'home' server so I wrote script that does sync from S3. But there is a window of (at least) one minute in synch. Now I see two solutions on the problem of pics not been available on 'home' server here: 1.I write script on EC2 (where the app resides) to fetch from DB pics that have status of "not-yet-synch", which is default state when user uploads picture. The script then does a ping to picture and if it gets OK response, updates DB from "not-yet-synch" to "synch". 2.Prefered solution would be to let apache (in this case) redirect request for an image if it sees 404 (e.g. doesent find image requested) to S3. This way I wouldn't need script from solution 1. So what approach do you suggest I take in solving this redundancy problem? Or what is practice in production environments? To further clarify; I'd like so serve images first from 'home' server, if that fails serve them from S3. Tnx, Alan

• How to diagnose remote assistance problem

  - by cantabilesoftware

  I have a long standing issue with remote assistance between a home and work PC. My wife and I both use MSN messenger and I used to be able to control her PC at home via MSN Remote Assistance. Some time ago however this stopped working and I don't know why. We're both running the latest versions of MSN Live Messenger and I've checked the appropriate firewall ports are open, but it still doesn't work and MSN just says something useless like "The person isn't responding". Any suggestions for how can I diagnose this? More info: I just tried direct Remote Desktop between work PC and home PC and it works fine - so I presume all the appropriate ports are open. Just Remote Assistance doesn't work. I'd like to get RA working so I can demonstrate how to do things remotely. With Remote Desktop the person at the other end gets booted off and can't see. With Remote Assistance they can follow along step by step. Some comments below suggest using other solutions, which is fine and do work, but there must be a way to diagnose RA and get it working. Experimenting with this some more, the notebook that I was using at work today that refused to connect works fine for remote assistance when I bring it home. So I guess this must be a problem with our network configuration at work. I've checked that 3389 is open on firewall on office router and remote desktop works both ways.... just not remote assistance. I've read that remote assitance won't work if client and server are both behind Non-UPnP/NAT routers. If one has UPnP it's supposed to work. Office router doesn't have UPnP enabled but my home one does. I've also scoured the event logs on both ends, nothing noteworthy - unless I'm looking in the wrong spot). Note (copied from comment): I've just tried ShowMyPC which is based on VNC and it works, but I'd still like to figure out what's wrong with RA - it's just bugging me. The question is only about Remote Assistance, no need to propose solutions based on other programs.[/edit by Gnoupi]

• hdfs configuration

  - by Ananymous

  I am a newbie. Trying to setup a hdfs system to serve my data (I don't plan to use mapreduce) at my lab. So far I have read, cluster setup in but I am still confused. Several questions: Do I need to have a secondary namenode? There are 2 files, masters and slaves. Do I really need these 2 files eventhough I just want hdfs? If I need them, what should go in there? I assume my namenode in masters and datanodes as slaves? Do I need slaves nodes What configuration files are needed for namenode, secondary namenode, datanode and client? (I assume core-site.xml is needed for all 4)? In addition, can someone suggest a good configuration model? sample configuration for namenode, secondary namenode, datanode, and the client would be very helpful. I am getting confused because it seems most of the documentation assumes I want to use map-reduce which isn't the case.

• Looking for a host based network monitor solution

  - by Ole Martin Handeland

  Hi all! Problem So, my hosting company has a network usage graph for my dedicated server. It seems that one day earlier this month, my network usage suddenly spiked with several hundred megabytes transferred (usually it's in the tens, not hundreds). It was probably me, but i just can't be sure who or what it was. Question So my question is; does anyone know of any host based solution for monitoring network usage that would tell me the client's IP-address, the port/service he/she used? What I don't want I'm just guessing that someone will suggest i use nagios, munin, zabbix, cacti, mrtg - I've also looked at those, but a graph over network usage will not give me the answers I'm looking for. :-) Almost there I've already looked at a lot of monitoring solutions, and I've tried [ntop][http://www.ntop.org/], [darkstat][http://unix4lyfe.org/darkstat/] and others. Darkstat just didn't give me the answers. Although it listed a lot of statistics, and i could list the clients - it doesn't show me the network usage for a particular period. Ntop is by far the best I've seen so far - but i think it mostly shows current network usage, not the historical part. I could run apt-get upgrade and download a whole bunch of software, but not see it in the log afterwards.

• Trouble getting latest version of Git

  - by TheMethod

  I am using Ubuntu 10.04 LTS. I'm looking at using git as source control for personal projects and Github as a remote repository. I was having trouble pushing a commit to my remote github repo getting the following error message: The requested URL returned error: 403 while accessing https://github.com/Jstall/helloworld.git/info/refs When I did some digging I found that the problem could be me not having the latest version of Git. When I did a --version I found that I have version 1.7.0.4 locally. So I tried to update git using: sudo apt-get install git but get the following error: Reading package lists... Done Building dependency tree Reading state information... Done Package git is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package git has no installation candidate I've tried running: sudo apt-get update and trying again but it didn't seem to make a difference. I'm not sure if it's relevant but I'm also getting a couple of 404's when I run update: Err http://wine.budgetdedicated.com edgy/main Packages 404 Not Found Fetched 4,117B in 0s (5,142B/s) W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/edgy/universe/binary-i386/Packages.gz 404 Not Found [IP: 91.189.91.15 80] W: Failed to fetch http://wine.budgetdedicated.com/apt/dists/edgy/main/binary-i386/Packages.gz 404 Not Found I'm not sure when I should try next. Could anyone suggest a course of action to get this resolved? Any advice would be appreciated. Thanks much!

• Notebook Operating System with extreme support cycles/security updates

  - by leto

  Hello there, after reading the announcements about Mac OS X "Lion" and Apples political decision, I've had enough. I'm a longtime Apple User since 1992, have always felt at home there, but am trying to switch to alternative Operating System since a year. I've also been working with Unix machines since 2001, so I'm looking in one of the free Unices or a Linux. Since I last looked at the desktop in 2002 choke much has changed, it seems. So I'm lost once more in the war between desktop environments and software. To be honest: I don't care what it's name is, I want to get my job done. Here's what I set me as landmark for an operating system/software to be considered: Has to be atleast four years old Has to supply security updates for current release for atleast a year Production quality stability for the whole desktop environment (!) No f****g commercial stuff that tends to supply me with privacy invading App Store or Cloud space So far I'm running a MacBook from 2007, 4 Gig memory, 250 Gig disk and I need: IMAPs for Mail since 1995 Webbrowser sic Shell Keeping current with Updates/Upgrades with no more than 5 Minutes spent in entering commands (makes it hard for OpenBSD ;-) ) A desktop filemanger would be nice, but is a bonus. What can you suggest as operating system? The one with the longest support cycles and best chance to survive the next 10 years will win a new user, even sending patches when needed :-) Greets

• Build suggestion for mini itx server [on hold]

  - by Spyros

  I am looking to create a home server and since there does not seem to be a nice ready made one to purchase, i thought of building a mini itx one. I am not familiar with the best hardware/case to pick and therefore i thought i would ask for your experience. I will most probably install a simple linux distro, probably Debian and most probably without a desktop environment as well. Therefore, I am not looking for the best graphics card, though a decent one is preferred for sure. I would say that the most important thing is that the case/hardware play well with each other and the machine has decent specs ( i think something like 8gb RAM and 1TB hdd is most probably my most important things). I understand that this question can be closed as subjective, but it would be a great help for me if some of you guys who have been doing a similar build, can suggest something. I tried to find a stack exchange variant for the question, but it seems that this one more closely relates to the subject. But I will definitely understand it if people close it due to being subjective in nature. If you can maybe move it somewhere or so, please feel free to do so. Thank you for your time :)

• Auto Log-Off Windows users - Windows 2003 domain

  - by thehatter

  Hi! I am trying to make windows clients automatically log off after some time, I have been trying to use the winexit.scr which I have seen working else where in a similar environment. After working though these instructions (I did read the comments and notice the original ADM provided is buggy) I've had no joy what so ever! Winexit.scr refuses to read any settings in the registry, even while using a test account I can access the required reg key(s); edit, add, and remove values. Essentially winexit.scr always uses it's default values: 30 second timeout, no forced log-out. What I really want is a 30 minute timeout with a forced log-out, closing all the users apps etc. I've tried removing and re-adding the ADM template, creating the GPO from scratch several times, giving various registry permissions - including full control to "Everybody" just for fun! Oh, clients are all win XP SP3, DC is win 2003 R2 SP2. So, can anybody suggest something? Cheers!

• Creating Routes using the second NIC in the box

  - by Aditya Sehgal

  OS: Linux I need some advice on how to set up the routing table. I have a box with two physical NIC cards eth0 & eth1 with two associated IPs IP1 & IP2 (both of the same subnet). I need to setup a route which will force all messages from IP1 towards IP3 (of the same subnet) to go via IP2. I have a raw socket capture program listening on IP2 (This is not for malicious use). I have set up the routing table as Destination Gateway Genmask Flags Metric Ref Use Iface IP3 IP2 255.255.255.255 UGH 0 0 0 eth1 If I try to specify eth0 while adding the above rule, I get an error "SIOCADDRT: Network is unreachable". I understand from the manpage of route that if the GW specified is a local interface, then that would be use as the outgoing interface. After setting up this rule, if i do a traceroute (-i eth0), the packet goes first to the default gateway and then to IP3. How do I force the packet originating from eth0 towards IP3 to first come to IP2. I cannot make changes to the routing table of the gateway. Please suggest.

• Error related to pkg-config when installing frei0r as part of another package

  - by Anentropic

  I am trying to build https://github.com/mltframework/shotcut on OS X Lion (using their script in scripts/build_shotcut.sh) and after numerous hurdles I'm stuck on this error: ./configure: line 16062: syntax error near unexpected token `OPENCV,' ./configure: line 16062: `PKG_CHECK_MODULES(OPENCV, opencv >= 1.0.0, HAVE_OPENCV=true, true)' ERROR: Unable to configure frei0r From what I already googled this means that the PKG_CHECK_MODULES macro hasn't been defined, which probably means there's something wrong with my pkg-config, which I installed via Homebrew. Sounds like the pkg.m4 file isn't found. When I brew install pkg-config I get the following warning: Warning: m4 macros were installed to "share/aclocal". Homebrew does not append "/usr/local/share/aclocal" to "/usr/share/aclocal/dirlist". If an autoconf script you use requires these m4 macros, you'll need to add this path manually. Well I've appended that line to the dirlist file and it doesn't fix the problem above. Can anyone suggest a way forward here? I have briefly tried building my own pkg-config from source but (bizarrely) when I tried to ./configure I got the following error: checking for pkg-config... no ./configure: line 13540: --exists: command not found configure: error: pkg-config and glib-2.0 not found, please set GLIB_CFLAGS and GLIB_LIBS to the correct values if building pkg-config needs pkg-config it seems like a weird catch 22 situation... I think this is probably an unnecessary sidetrack anyway.

• Hosting a server for websites, ftp and random use at home?

  - by Zolomon

  I'm wondering what's the best option for me if I want to move all my hosted websites (from a hosting company) to a server at my own home? Basically, the needs I have are: be able to host websites using PHP/ASP.NET (haven't really decided yet - both would be preferred!) enable FTP so I can create accounts for my family members to access the server for file handling SSH SSL - for secure connections (this is something you have to buy/apply for per domain, not sure if there are any server side settings that have to be made) be able to stream video remote desktop host home-brew applications that can run as services use either MySQl/SQLite/SQL for relational database storage What should I think of before I buy a server? What hardware will I need, what will limit my server? I basically want to learn networking better as I'm a software and web developer but haven't had the resources to acquire any serious toys until now. At the time of writing, most of my websites have 60 visits/day so I don't suspect them to be very demanding. Is there something I haven't thought of that I should have? What OS would you suggest I run? FreeBSD vs Windows Server vs ?

• How do I collect SNMP readings from intermittently-connected sites?

  - by Luke404

  I am collecting SNMP data on-site for a number of systems, currently using Cacti. These systems are spread on a number of sites that aren't always connected to internet, but I also need to centralize the data on a single system (datacenter housed server) and get graphs out of it. If I directly poll remote systems with a centralized Cacti I'd loose data when a site is not connected to internet. I should record data on-site (I have a server at each site and I can run whatever I want on it) and then 'sync' everything to the central system. One hack could be a cacti or directly an rrdtool on site and then periodically rsync RRD data to the central Cacti system, but that doesn't sound like a 'clean' solution: every RRD would have to be defined at both places and rsync scripts setup with the specific file names. Can you suggest a better solution? Cacti is not a requirement but I'd like to use something like that on the central system. On-site systems need only to collect data I don't need to graph it there or manage users rights to view data and stuff like that, users will only access the centralized system.

• Making one of the folders default in Apache

  - by OmerO

  Hello, The file & directory structure of my website is as follows: /Library/WebServer/mysite/joomla .. /Library/WebServer/mysite/wiki .. /Library/WebServer/mysite/forum .. /Library/WebServer/mysite/index.php As you see, there are various applications each residing in separate folders. Now, in order to define this structure, I have made this entry in Apache http-vhosts.config file: ServerName mysite.com DocumentRoot "/Library/WebServer/mysite" ** And I already have the DirectoryIndex defined: DirectoryIndex index.html index.php, and so on. So far so good but I want this specific functionality: When someone visits mysite, he/she should automatically directed to: /Library/WebServer/mysite/joomla (and therefore /Library/WebServer/mysite/joomla/index.php) I don't want to achieve that functionality by putting a redirection code inside /Library/WebServer/mysite/index.php or /Library/WebServer/mysite/index.htm because that causes time delays (because of the redirection, of course) But in this case, the only proper way of achieving it seems to set DocumentRoot this way: DocumentRoot "/Library/WebServer/mysite/joomla" But when I set it that way, then the other folders (/wiki, /forum, etc.) are simply not served by Apache. To work around it, I put directives like: Alias /wiki /Library/WebServer/mysite/wiki .. Alias /forum /library/WebServer/mysite/forum and it did work actually the way I wanted. But... I still cannot use it that way because in this case I just couldn't manage to make the wiki use Short URLs (as described in link text) So, I have to set the DocumentRoot back to /Library/WebServer/mysite and shoud be able to assign /Library/WebServer/mysite/joomla as the "default directory" (my own terminology :) Can I do it in Apache? Is there any other way you might suggest? Thanks.

• Domain changes required for SSL integration

  - by user131003

  Currently my site supports regular payment options (User is taken to Payment Gateway/PG website). Now I'm trying to implement "seamless" PG integration. I need SSL for this. I'm having a dedicated server with 5 static IPs from Hostgator/HG. options: I take SSL for www.my_domain.com. According to HG, I need to change IP of main site as current IP is not really dedicated as it is being shared by cpanel etc. So They need to bind another dedicated IP to main domain for SSL to work. This would required DNS change for main website and hence cause few hours downtime (which is ok). I've noticed that most of the e-commerce websites are using subdomains like secure.my_domain.com for ssl/https. This sounds like a better approach. But I've got few doubts in this case: a) Would I need to re-register with existing PGs (Paypal, Google Checkout, Authorize.net) if I switch to subdomain? Re-registering is not an option for me. b) Would DNS change be required for www.my_domain.com in this case. This confusion arose because of following reply from HG : "If the sub domain secure.my_domain.com is added to an existing cPanel it will use the IP for that cPanel so as long as it is a Dedicated IP that will be fine. If secure.my_domain.com gets setup as its own cPanel it will need to be assigned to a Dedicated IP which would have a DNS change involved.". PLease suggest.

• should i link to a blog site or install my own blog engine?

  - by dc

  we're setting up a company blog. Our technology stack is .NET. Should we just use blogger/wordpress for the blog and redirect to it from our site? or should i install a blog engine directly on our site (e.g. blogEngine.NET)? some considerations i'd like feedback on are: 1.SEO - if you host your blog on wordpress/blogger instead of installing it on your site - will you get better page rankings? (if the content was the exact same) 2.scalability - i've read that dotNetBlogEngine doesnt scale well on web farms etc. our website is setup to be stateless. 3.security - presumably a hosted blog site has the advantage of having regular security updates. how easy is it to keep an installed blog engine patched? 4.examples of installed blog engines - dotNetBlogEngine seems to be the best but has a couple of limitations. can anyone suggest another one (n/a if you're advice is to host the blog on blogger/wordpress) 5.any other comments/issues/concerns we should be aware of? thanks for your feedback!

• Problem in accessing Windows shared folder on Ubuntu using terminal

  - by vikramtheone

  Hi Guys, Description I have 2 systems with me, one running on Windows(Host) and one on Ubuntu, both on a LAN. On the Windows(Host) I develop software intended for the Linux system and because the Linux system has little external memory, my idea to overcome this is by making the project folder on the Host side a Shared Folder with full access and access it on Ubuntu over the network. To achieve this, I have installed Samba on Ubuntu, when I go to Places -> Network I can see the shared project folder and I simply mount it. A link appears on the desktop. Next, using Nautilus I open the link and I can access the contents of the shared folder. Problem Even though I mount the shared project folder, I don't see it appearing in the /media or the /mnt folder, as a result of this I don't know what path to use to access this folder, from the terminal. For example: When, I mounted my USB stick, as expected, a link for the device appears on the Desktop and I also see a folder in the media folder. So, similarly, a mounted shared folder should have appeared on the /mnt folder, too. Can anyone suggest what I should do now? There are many posts around, but no solid solution for this problem. Help!!! :) Vikram

• IE6 does not follow 302 redirect - displays 404 instead

  - by Dexter

  One of our clients has reported that they are experiencing 404 (file not found) errors when attempting to navigate a website that we support. The behaviour only appears to affect her - other users on the same machine can navigate the website fine, but the problem follows her from one PC to another. I've had a good look through the IIS server logs and have identified the requests in question. The normal request pattern is as follows: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 - ... 401 1 0 GET /anotherPage.aspx Request=833f80a5-f34c-4b0e-addb-d73e1ee1663a 80 DOMAIN/user ... 200 0 However, requests for the affected user do not include a request for the redirected page, nor an entry for the 404, i.e.: POST /page.aspx - 80 - ... 401 1 0 POST /page.aspx - 80 DOMAIN/user ... 302 0 0 ... other unrelated requests Can anyone suggest what might trigger this behaviour, and how I might investigate the cause or prevent it from occuring? I read here that the Allow META refresh option in IE6 might trigger this behaviour, but I have not been able to replicate the behaviour by modifying this setting only.

• What Is The Proper Laptop Battery Care While Running Laptop Solely On Battery?

  - by Boris_yo

  Because of convenience, I had to move my laptop to another room away from room where I always ran laptop on UPS without using battery. Since so far I always run laptop on battery, I question the proper usage to prolong battery life. Currently I run laptop on battery with power supply so battery is constantly being charged until it is full 100% and when it is, I disconnect power supply and continue working until battery meter shows 10% remaining. That's when I plug in power supply and let it charge until 100% once again while I work. But it takes a lot of time to fully charge laptop while working since my power supply is 60W which should be the reason of such slow charge and I think the kind of charger that I use is express charger. The thought of charging laptop until full, all while doing my work makes me think that if it takes way more time to charge, it might keep battery running warm for the period of charging time which brings me to question about whether I should keep running laptop as I've described above or it would be better to leave power supply constantly connected to laptop to keep battery between 99%-100%? On one hand it won't keep battery warm but it will try to frequently supply charge to battery once it gets 99% to replenish charge to 100% (which might reduce battery life?). On the other hand if I'll keep working solely on battery and recharge it when below 10%, the battery will get warm but only when charged. Can anybody suggest the correct way of running laptop on battery to ensure better battery life? Dell Latitude E6420 Windows 7 64-bit

• Virus on site but can't find where

  - by Rob

  WARNING! THIS IS ABOUT A VIRUS ON MY SITE. IT APPEARS IT HAS BEEN THERE FOR SOMETIME AND I'VE HAD NO PROBLEMS. BUT PLEASE BE CAREFUL. READ EVERYTHING I SAY AND SEE IF YOU CAN HELP ME WITHOUT VISITING THE LINK. AVG PICKS UP ON IT AND BLOCKS IT, MCAFEE DOES NOT. Sorry about the warning, obviously i'm not here to get anyone infected or anything like that. Basically I run the website sortitoutsi dot net. Ages ago I got a virus on my computer, they got hold of my FTP passwords and added some lines of javascript to the top of my site. I removed them and believe it was fixed. However i'm using the "Web Developer" extension for Firefox and chose to view all javascript on my page and find there are various links to horrible urls such as: gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/aboutus.org/aboutus.org/google.com/skycn.com/torrents.ru.php and gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/index.php?jl= These terms do not appear anywhere. In the source code, in any of the javascript or the css. I also can't see that there are any rogue images that I don't recognise either. So i've no idea where this javascript is coming from. Can anyone suggest how I can find references to these links and remove them? I can see them both in the Web Developer firefox extension and in the net tab using Firebug. Any help would be greatly appreciated

• Emptying Windows temp folder is a good idea?

  - by Siva Charan

  Am using DELL Inspiron with Windows 7. As far as I know emptying the windows temp folder would be good. But I faced a strange behaviour around 8 months back, when I clear my windows temp folder. The next day onwards, my laptop starting displaying daily one or other errors and one day OS got crashed. Till now I am not sure whether OS got crashed due to clearing the windows temp folder or something else is problem. Here Windows temp folder mean "C:\Windows\Temp" This is the behind the story. Today, this temp folder "C:\Windows\Temp" contains 102 GB Most of the space occupied by the files starts with etilqs_*.*. I came to know that these files are generated due to WD SmartWare. Now my problem is:- Actually I want clean up this folder, since it occupies lot of space. If I clean up "C:\Windows\Temp" folder, will my laptop face the same kind of problem which I faced earlier OR Any new problems will occur? Please suggest me a good solution.

• How can I tell my dd-wrt router to use someone's Amazon Affiliates link when I point my browser to amazon.com?

  - by Michael Paul

  Here's what I'd like to do. Instead of a one-time donation to one of my favorite free tools (junecloud.com) I'd like to do what they suggest here and use their Amazon Affiliates link to do all my Amazon shopping. I shop at amazon once or twice a week, so this is a great way to let them earn lots of long-term cash without me dropping a dime. My thought was to go into my dd-wrt enabled router and tell it, "any time I go to amazon.com on any computer in the house, please go to http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=junecloud-20&camp=1789&creative=9325&location=%2F instead. (That URL simply redirects me to amazon.com but every purchase I make during that session is credited to JuneCloud.) Once logged into dd-wrt, I went to Services Services DNSMasq but I'm not really sure how to get it to work from there, or if it's even possible. I know I can redirect IP addresses, but I'm looking to redirect someone on my network from amazon.com to the special amazon affiliate code link. Hope that's clear. Thanks for any replies!

  We have a system in the field running a server application which is suffering with major performance issues. The system in question has 2 onboard 300gb sas drives in RAID 5 from which it boots Windows Server 2003, and a 6tb buffalo terastation NAS unit (also RAID 5) to which the server app does all of its reading and writing. I believe the terastation is the source of all our woes. Whilst under load, reads and writes tick by at something of the order of 1meg/sec, though the network in question is hardly utilised. The terastation contains various data, but crucially hosts a full instance worth of SQL Server .mdf and .ldf files (master etc - the whole shooting match) I wish to stop all the services on the server, then take everything on the terastation and essentially clone it to some alternative onboard storage, so as to eliminate the terastation from the equation as far as poor performance is concerned. ie the terastation is currently drive D: - I want to copy everything off and then have the duplicate assume the drive letter so that as far as the software is aware, nothing is different. This is tricky because of the mdf and ldf files - everything else will work with a straight up file copy. Can anyone suggest a means to achieve what I am describing? Many thanks!

• Use of backreferences in fail2ban filters possible?

  - by Izzy

  From time to time, I see collections of suspect "File not found" errors in my Apache logs, basically using the pattern File does not exist: /var/www/file, referer: http://my.server.com/file In human terms: The file was not found, though it referenced here itself. A clear hacking attempt, as that's hardly possible (and the REQUEST_URIs often enough suggest the same). In my eyes a clear case for fail2ban – if I could get backreferences to work here: failregex = ^%(_apache_error_client)s File does not exist: /var/www(.+), referer: http://.+\1$ (Justin Case: above examples assume the DIRECTORY_ROOT of that webserver being /var/www) I googled for hours, searched the fail2ban wiki up and down – but nowhere I could find a statement concerning backreferences in its filters. Are they not supported, or did I do it the wrong way? Any hints how to make it work (except from "dirty hacks" like first sending the request to another fake url using mod-rewrite, and then catching on that (if anyone is interested, I can elaborate on that approach in an answer), or doing something similar using mod-security)? as an entire log line was requested: [Fri Nov 08 14:57:28 2013] [error] [client 50.67.234.213] File does not exist: /var/www/text/files.htm++++++++++++++++++++++++++Result:+using+proxy+27.34.142.47:9090;+no+post+sending+forms+are+found;, referer: http://www.myserver.com/text/files.htm++++++++++++++++++++++++++Result:+using+proxy+27.34.142.47:9090;+no+post+sending+forms+are+found; (sorry, logs were just switched, so this long candidate was the only one left currently; minor adjustments were made for privacy reasons)
