• Can files deleted on an ecnrypted drive be restored?

  - by roddik

  Hi. There are ways to restore files, deleted from the system by default, I'm not sure about the way they work but I guess thet read content, that has not been overwritten. On the other hand, there are programs (e.g. TrueCrypt), that encrypt disks, claiming that it wouldn't be possible to tell apart random data and file contents on such a disk without a password. Therefore I think that files, deleted from such disks can't be restored. Is that correct? I know one way to find out would be to try it, but there is a possibility, that I would just pick the wrong restoring software. Moreover, I'm more interested in theorethical explanation why it would/wouldn't be possible. Thanks

• Store system passwords with easy and secure access

  - by CodeShining

  I'm having to handle several VPS/services and I always set passwords to be different and random. What kind of storage do you suggest to keep these passwords safe and let me access them easily? These passwords are used for services like databases, webserver user and so on that run customers' services, so it's really important to keep them in a safe place and strong. I'm actually storing them in a google drive spreadsheet file, describing user, password, role, service. Do you know of better solutions? I'd like to keep them on a remote service to make sure I don't have to make backup copies (in case my hdd would fail somehow). I do work on *nix platforms (so windows specific solutions are not a choice here).

• Understanding IUSR_<machine> account

  - by liho1eye

  Namely how is setting read/write permission for this account different from giving read/write access in the IIS (Windows 2003, so it should be IIS6 if I am not mistaken). Here is the issue: It looks like we had a security sweep and as a part of that IUSR account lost write access everywhere. A whole bunch of legacy ASP sites didn't like that at all... My very surfacish understanding is that it is enough to deny write access in the IIS console to protect a website from someone just dropping random files into it, and IUSR access only has effect on the application scripts running server side, and thus can be safely given write access back. edit: The applications in question obviously require write access to their own web folders, otherwise this wouldn't be an issue at all. Question is how to configure IIS/application to both satisfy security and make them work. My first instinct was to change account which is used to run the app pool. However that is already set to NETWORK_SERVICE, and that guy already has full access to folders in question.

• Can't resolve Mac's machine name on VPN

  - by Raghuveer

  My mac'c machine name is something like this: hostname.company.com but whenever I connect to VPN, it becomes something like vpn-xxxx.company.com where xxxx are some random numbers. Because of this, some of my scripts which are dependent on host name gets blocked. We use the standard mac's vpn setup which comes with OS X Lion (under network preferences). How can I resolve to the correct mac's name even if I am on vpn ? That is even if I am connected to VPN, my machine name should resolve to hostname.company.com and NOT to vpn-xxxx.company.com. Any suggestions would be really appreciated.

• NAS device for distributed team

  - by user5959

  We are a distributed team spread across 5 locations. We have a shared drive (1 TB data) at our former location that we are currently accessing via Hamachi VPN. Our shared drive is a network folder on a Windows Server located at one of our locations. The current connection speed is terrible. The upload speed at the current location of the shared drive is very slow. We looking for a NAS device that we can host at another location with better upload speed that all of us can access. I am looking for a NAS device that has these features: Minimal Maintenance as we do not have dedicated IT resources Access data on the device from multiple locations. Ability to create network drive (On Windows Computers Map Network Drive) Upload data from random client computers without having to install software. (Right now, we use LogMeIn Rescue's file manager) Ability handle slow or dropped connections when transferring files (Maximum size 1.5 GB)

• Can you span a single file share across multiple servers?

  - by Mike C.

  Let's say I have one large file server that has a company-wide share. That file server constantly runs into space issues. Now let's say I have a dozen or so random servers (print servers, web servers, etc) that have a ton of free space. Is there a way to utilize that in the company-wide file share? Like spanning the storage across different servers but making that transparent to the user? I know the likely answer is going to be get more storage for the file server, but I just curious if this is conceptually possible. Thanks!

• how to fight back attacks on my web service

  - by user12145

  My apache webservice is getting a large quantity of requests over the days, each one with somewhat random login to gain access. I identified about 60 such ips(a few sample below), all belong to google. is there a way to find more information about the origin of the attacker? or should I just block these ips. secondly, should I attempt to block the identified ips subnets(74.125.46.*) as a preventive measure? 72.14.194.65 64.233.172.20 74.125.75.19 72.14.194.33 74.125.46.87 74.125.44.91 74.125.46.91

• which mail server is better suited for high volume? [closed]

  - by crashintoty

  I'm planning out a project (web/mobile app) that would require a mail server that could handle hundreds of thousands connections per hour (both IMAP/POP and SMTP) and has the ability to interface with PHP (or python or whatever) to dynamically create, delete and check for mailboxes? This is not for spam stuff, I just need my app to generate random mailboxes (and static/permanent ones too) to receive mail and process it for items listed on my service. The little research I've done so far has turned up courier, dovecot, cyrus and haraka. I think the ability to scale and/or load balance (I'm new to these terms, pardon me) would also be a requirement. Any ideas?

• How to set up VPN connection? Virtual Box 3.1.4 installed. Host - Snow Leopard(Mac) Guest - Windows

  - by user31954

  I have Virtual Box 3.1.4 installed. Host - Snow Leopard(Mac) Guest - Windows 7 (32-bit). I have installed Windows on my MAC because I need it for work. I cannot establish VPN connection (using NAT). I tried to use bridged adapter, and I lost my internet connection on my guest(wind7) completely. I don't know much about networking, so I need detailed instructions for his particular OSs. Could someone please help me with this? Some random details about my attempts: On my host Windows I get error 800 trying to VPN. I can ping server address from my guest Win 7 and I have VPN connection established from my host Mac. I do disable VPN on my Mac when tying to establish it through guest. I tried to VPN from Mac and see if Guest sees it. It doesn't. Thank you!

• a safer no password sudo?

  - by Stacia

  Ok, here's my problem - Please don't yell at me for being insecure! :) This is on my host machine. I'm the only one using it so it's fairly safe, but I have a very complex password that is hard to type over and over. I use the console for moving files around and executing arbitrary commands a LOT, and I switch terminals, so sudo remembering for the console isn't enough (AND I still have to type in my terrible password at least once!) In the past I have used the NOPASSWD trick in sudoers but I've decided to be more secure. Is there any sort of compromise besides allowing no password access to certain apps? (which can still be insecure) Something that will stop malware and remote logins from sudo rm -rf /-ing me, but in my terminals I can type happily away? Can I have this per terminal, perhaps, so just random commands won't make it through? I've tried running the terminal emulations as sudo, but that puts me as root.

• Why do I have inconsistent network issues with my laptop's wireless?

  - by Jason

  I'm having trouble with my laptop Internet connection. It's patchy at best and resets or freezes a lot. The signal strength is also random. I thought it might be a driver issue but now I don't know. Three other computers using the same wireless network run well. I've switched out wireless routers so I don't think it's the router. I thought it might be the laptop's internal wireless card but I just bought an external USB network card and I'm still having problems. Specs Lenovo T-60p Windows 7 Ultimate Edition Patches/drivers are up to date I only use one of the below at a time, disabling the other: Intel PRO/Wireless 3945ABG v. 13.3.0.137 (Internal wireless) Medialink Wireless-N USB 2.0 Adapter (USB wireless) Any ideas on what might be the problem?

• SUSE linux nginx and phpmyadmin 404 errors

  - by user968808

  I've installed nginx and phpmyadmin etc and most things work fine. I'm getting random problems though... e.g. when I click drop I get a message on the screen to say its updating and then the page does not refresh afterwards. Also randomly get 404 errors if I check all when trying to delete rows out of a database. Or if I import a file over around 10-20 rows i get 404 page not found. Where have I gone wrong?

• How do I audit CD/DVD tray opening events in Windows 7?

  - by MetaHyperBolic

  Since installing Windows 7, the entire office has experienced random CD tray openings, sometimes while we are in the office, sometimes not. On my PC, I have two disc-reading devices, but only the top one ever slides open. I have found nothing in the event logs to that looks appropriate, even going to them right after I saw my own tray slide open all by itself. Although it's not hurting anything (that I can tell), I'd like to know what is going on. To that end, are there any useful ways to audit these events?

• Analyse frequencies of date ranges in Google Drive

  - by wnstnsmth

  I have a Google Drive spreadsheet where I would like to compute occurrences of date ranges. As you can see in my sheet, there is a column date_utc+1 which contains almost random date data. https://docs.google.com/spreadsheet/ccc?key=0AhqMXeYxWMD_dGRkVGRqbkR3c05mWUdhYkJWcFo2Mmc What I would like to do is 1) put the date values into bins of 6 hours each, i.e. 12/5/2012 23:57:04 until 12/6/2012 0:03:17 would be in the first bin, 12/6/2012 11:20:53 until 12/6/2012 17:17:07 in the second bin, and so forth. Then, I would like to count the occurrence of those bins, such as bin_from bin_to freq ----------------------------------------------- 12/5/2012 23:57:04 12/6/2012 0:03:17 2 12/6/2012 11:20:53 12/6/2012 17:17:07 19 ... ... ... Hope it is clear what I mean. Partial hints are very welcome as well since I am pretty new to spreadsheeting.

• External monitor turning black intermittently

  - by coding crow

  I have installed an external monitor (Dell ST2220L, 21.5 inch) on my laptop (Sony Vaio). I am using a DVI-D cable for connection. Since the laptop does not have a DVI-D port, I have connected a DVI-D to HDMI connector on the laptop end and inserted the cable in HDMI port of the laptop.. I have switched off the laptop display and adjusted the screen resolution on the Dell external monitor to 1920 x 1080 and adjusted colors for the Windows 7 and brightness and contrast from the monitor. The problem is the monitor turns of blank intermittently for 1-2 seconds and turns on again at random interval. What could be the reason for this and how to get rid of this problem?

• Songbird very slow, freezes

  - by Cawas

  I've read on few places that Songbird is no good with more than some thousands of library items because it starts getting quite slow. Well, in my case (which is a clean install) I've imported 17k items (which I know is not that much) and instead of becoming just too slow it frequently gets to not responding for several minutes until getting back to its senses again. That's for whichever random operation such as deleting 1 item from library. I've also read on few more places that gives very little hope on fixing this issue, but I wonder... Is there any way to tweak it and make it work as fast as expected? Am I missing something or is the software just not intended for libraries with more than 10 thousand thingies?

• My email server emails are being refused by some servers

  - by Havenard

  I have a Microsoft Exchange Server 2003 installed in my office. It was configured with all MX-records and SMTP relaying recomendations required to gain trust and not have my server blacklisted. It is also aparently not blacklisted in any email server blacklist I can find online, and in overall it works. I can send emails to Gmail, Hotmail, and most other email servers. Howover, some few email servers insist in not receiving my e-mails for some random reason I couldn't so far understand. There is no error, they simply drop it. Is there something I can do to get this mystery solved?

• Emacs equivalent of this Vim command to run my tests?

  - by eightbitraptor

  I'm using Emacs at the moment and experimenting with it for my Rails development and there is one thing that I do quite regularly in Vim and I'd like to know if an equivalent exists in Emacs, or an alternative workflow to achieve the behavior that I need. The command in Vim is :map ;t :!rspec --no-color %<cr> Essentially this maps a key combination to run a bash/shell command on the file represented by the current buffer (% expands to the filename at runtime, the <cr> is just a carriage return at the end to execute the command). I map all sorts of random little commands as and when I need them and I really miss the immediacy of this approach. How can I achieve something similar?

• How can I keep the Windows 8 virtual keyboard from popping up?

  - by orbfish

  I am the unwilling recipient of Windows 8. Lenovo couldn't fix the new Windows 7 Ultrabook I bought, so they sent me a Yoga laptop, with touch-screen and Windows 8. Once I bought a start menu replacement, I don't mind Windows 8 too much - it's ugly, but most things work as well as Windows 7. But the thing that drives me crazy, endlessly, is the virtual keyboard popping up when I'm trying to do something else (well, just about anytime, since I almost never use it to type). It's like a giant Clippy that covers half the screen. I haven't figured out what causes it to pop up. It seems pretty random, and sometimes it goes away before I can even reach for the escape key. Sometimes it comes up when I'm typing, sometimes when my hands are nowhere near the keyboard. Sometimes several times a minute, sometimes not for hours. Any suggestions?

• Windows 8: 100% disk active time, no actual data transferred

  - by fingerbangpalateclick

  Occasionally, like several times an hour, my hard drive will appear to lock up: Task Manager will show 100% active time with read and write speeds of 0. I can still switch between open windows, but anything that requires a disk access will stall for around a minute until the hard disk starts working properly again. It happens at apparently random intervals, and only happens in Windows 8. Not 7, nor Linux. It is probably not a problem with the disk itself: This is a relatively new hard drive, and S.M.A.R.T. is showing no errors. Only happens in Windows 8: not any other OS that has used the same partition, or different partitions. So, what is going on? How can I fix this? Note: this is a different problem then this one: Extremely high disk activity without any real usage My task manager would look similar, but Average Response Time, Read Speed, and Write Speed would all be 0.

• USB Mouse disconnects ONLY on bootcamp (win7,works fine on OSX) [duplicate]

  - by gourounakis

  This question already has an answer here: Why is my USB mouse disconnecting and reconnecting randomly and often? 7 answers I have a mid 2010 iMac with a Logitech G500 mouse which works fine on OS X. I game on Windows 7 in bootcamp, and for a month now I have been getting random mouse disconnects while gaming. Sometimes none, sometimes 2-3 per minute. The mouse lights go off and I get the disconnect sound from Windows 7 then it connects again after a second or two. I tried changing the port I connect the mouse to, but still the same thing. The only devices on USB are Apple keyboard with Apple extension cord, the mouse, and a Creative SoundBlaster Tactic 3D Alpha USB Gaming Headset. Any ideas?

• all USB "randomly" disconnect and reconnect

  - by teuneboon

  I'm having a weird issue currently: at seemingly random times(although it seems to happen mostly when USB is used a lot, ie downloading + uploading over my WiFi stick or viewing an HD video from my external hard-drive) all my USB devices disconnect and reconnect after a few seconds. This wouldn't be a HUGE problem if I didn't have to rely on my USB for my internet, because now every time this happens my internet, and with it stuff like remote desktop, crashes. I'm running Windows 8 Pro 64 bit with a Gigabyte 990FXA-D3 motherboard. Now the weird thing: I had the same problem with my previous pc, which had a different motherboard(I think it was an Asus M4A785TD-V EVO). I googled a bit and didn't really find anything about this, only found out I could check if something shows up in the Event Viewer, and I get this error there when the USB crashes: "A timeout occurred while waiting for the EHCI host controller Interrupt on Async Advance Doorbell response." If you require any extra information I'm happy to provide it.

• RAID 10 over RAID 5 when using SSDs

  - by root

  I am considering implementing an iSCSI shared storage array using SATA SSDs instead of the 15k RPM SAS drives we normally purchase. We normally use RAID 10 because of spindle contention with the random IO produced by virtualized workloads. I was wondering if we could switch to RAID 5 or RAID 6 to have more usuable space now that spindle contention is less of an issue. A question in my mind is how much overhead there is from the controller calculating parity. I am aware that this configuration will not allow TRIM to function. Our current workloads are running on a Dell H800 with a 24 bay external enclosure.
