  • Proxy server on windows with SSL encrypted exchange with client

    - by Syffys
    I want to set up a classic proxy server (HTTPS, HTTPS, SSH, FTP, etc...) on a windows platform, but I need the following features: password authentication for clients data exchanged between clients and server to be SSL encrypted I've been trying to set this up various application to get this result, but without success so far: Squid for windows ccproxy wingate Alternatively, an other solution would be an HTTP SSL tunnel encapsulating an unencrypted proxy connection between clients and the server. I've spent a lot of time without any result so far, so I'm wondering if anyone faced this kind of issue. Thanks in advance!

  • What is a "good" tool to password-protect .pdf files?

    - by Marius Hofert
    What is a "good" tool to encrypt (password protect) .pdf files? (without being required to buy additional software; the protection can be created under linux but the password query should work on Windows, too) I know that zip can do it: zip zipfile_name_without_ending -e files_to_encrypt.foo What I don't like about this is that for a single file, you have to use Winzip to open the zip and then click the file again. I rather would like to be prompted for a password when opening the .pdf (single file case). I know that pdftk can do this: pdftk foo.pdf output foo_protected.pdf user_pw mypassword. The problem here is that the password is displayed in the terminal -- even if you use ... user_pw PROMPT. But in the end you get a password-protected .pdf and you are prompted for the password when opening the file.

  • Access a windows dynamic hard drive through a virtual machine on ubuntu?

    - by Enigma
    I have a Windows 7 OS and am thinking about transitioning to a dual boot set up with Ubuntu 12.04. From what I recall, it is not possible to natively access Dynamic Windows Partitions in a Linux OS. My thought is that it might be possible to have a virtual machine (running windows) installed within Ubuntu access the physical dynamic drive. The problem comes to whether VMWare can access the physical disk "high enough" to be able to mount it within the windows virtual machine as a native device or if it gets passed through from the native Linux OS. This is really the only thing holding me back from switching to a dual-boot set up as the dynamic disk is made up of 4 or 5 hard drives and I would very much like access to the data on both OS's. Alternatively, is there another solution for combining multiple physical hard drives into one virtual hard drive that would be readable on both OS's?

  • Getting the EFS Private Key out of system image

    - by thaimin
    I had to recently re-install Windows 7 and I lost my exported private key for EFS. I however have the entirety of my user directory and my figuring that the key must be in there SOMEWHERE. The only question is how to get it out. I did find the PUBLIC keys in AppData\Roaming\Microsoft\SystemCertificates\My\Certificates If I import them using certmg.msc it says I do have the private key in the information, but if I try export them it says I do not have the private key. Also, decryption of files doesn't work. There is also a "keys" folder at AppData\Roaming\Microsoft\SystemCertificates\My\Keys. After importing the certificates I copy those over into my new installation but it has no effect. I am starting to believe they are either in AppData\Roaming\Microsoft\Protect\S-1-5-21-...\ or AppData\Roaming\Microsoft\Crypto\RSA\S-1-5-21-...\ but I am unsure how to use the files in those folders. Also, since my SID has changed, will I be able to use them? The other parts of the account have remained the same (name and password). I also have complete access to the user registry hive and most of the old system files (including the old system registry hives). I do keep seeing references to "Key Recovery Agent" but have not found anything about using, just that it can be used. Thanks!

  • Disk operations in windows 7 are slow

    - by Skadlig
    My computer started lagging last Sunday. I tried to reboot it and it failed. Trying to boot into failsafe mode takes around two hours. It mainly freezes on two files: scsiport.sys and classpnp.sys When it finally has started all disc operations are really slow. When it has run for a while it goes faster, probably due to data moved into RAM instead. It froze on an other file before that was associated with Avast but uninstalling it didn't really help. A critical windows update was installed on Sunday but rolling back the update didn't help. I had a guess about the sound card but disabling the sound card drivers also didn’t help. I have an inkling of an idea that it might be Intel rapid storage technology that might be acting up but it doesn't allow me to reinstall it from failsafe mode and I haven't been able to log into normal mode for a while. I would appreciate suggestions regarding how to get into normal mode again and/or what can be the root cause.

  • Fully secured gateway web sites

    - by SeaShore
    Hello, Are there any web sites that serve as gateways for fully encrypted communication? I mean sites with which I can open a secured session, and then to exchange through them with other sites in a secure way both URLs and content? Thanks in advance. UPDATE Sorry for not being clear. I was wondering if there was a way to access any site over the Internet (http or https) without letting any Intranet-proxy read the requested URL or the received content. My question is whether such a site exists, e.g.: I am connected to that site via https, I send it a URL in a secured way, the site gets the content from the target site (possibly in a non-secured way) and returns to me the requested content in a secured way.

  • How do I log file system read/writes by filename in Linux?

    - by Casey
    I'm looking for a simple method that will log file system operations. It should display the name of the file being accessed or modified. I'm familiar with powertop, and it appears this works to an extent, in so much that it show the user files that were written to. Is there any other utilities that support this feature. Some of my findings: powertop: best for write access logging, but more focused on CPU activity iotop: shows real time disk access by process, but not file name lsof: shows the open files per process, but not real time file access iostat: shows the real time I/O performance of disk/arrays but does not indicate file or process

  • Is it safe to remove Per user queued Windows Error Reporting?

    - by Rewinder
    I was cleaning up my laptop hard-disk, running Windows 7, and as part of the process I ran the Disk Cleanup utility. To my surprise I saw 2 items in the list that were quite large (both ~300MB). Per user queued Windows Error Reporting System queued Windows Error Reporting I guess I had never noticed these, because they were never that big. So, what are these items? Any particular reason why they became so large all of a sudden? And finally, is it safe to remove them?

  • SSH Tunnel doesn't work in China

    - by Martin
    Last year I was working in China for a few months. I never bothered setting up a real VPN, but just created a SSH tunnel, and changed my browsers proxy settings to connect through it. Everything worked great (except flash of course) but that was fine. However, now I'm back in China but I'm having problems with this approach. I do the same thing as last time, and according to https://ipcheckit.com/ my IP address is indeed the IP of my (private) server in the US, and I'm logging in to my server using a fingerprint I created long before going to China so no MITM should be possible. Furthermore the certificate from ipcheckit.com is from GeoTrust - so everything should be OK However, I still can't access sites which are blocked in China. Any idea how this could be possible?

  • Subversion hard disk full

    - by user37914
    Our SVN server hd was full. Deleted a load of unwanted data on there, and all appeared to be well. However, new check-ins are now failing. Can't move '/repos/db/txn-protorevs/1000-vr.rev' to '/repos/db/revs/1/1001': Permission denied 1000-vr.rev does not exist. There are two other files in there: 9-9.rev and 9-9.rev-lock Edit: I have checked file permissions just in case, and all is as it should be.

  • How to protect folder privacy against unethical network administrators? [closed]

    - by Trevor Trovalds
    I just need a technical solution for the sake of my group's shared passwords, projects, works, etc. safety. Our network has Active Directory with public/groups/users and NTFS permissions, under a Windows Server 2003 which will soon migrate to Windows Server 2008 R2. Our IT crowd is small, consisting of 2 DBAs, 4 designers, 6 developers (including me), 2 netadmins and (a lot of) tech supporters, everyone has local admin rights. Those 2 network admins weren't the ones who set the network up, they just took the lift recently when the previous ones quit. We usually find them laughing at private contents from users stored in the groups AD, sabotaging documents that don't match their personal tastes and, finally, this week we found out they stole a project we (developers and DBAs) were finishing and, long before, they presented it to the CEO as theirs without us knowing. I'm a systems analyst, and initially my group decided to store critical content, like shared passwords, inside encrypted .zip files. Unfortunately we couldn't do the same to the other hundreds of folders and files, which included the stolen project, because the zipping process would take too long for every update. We also tried an encrypted Subversion repository under SSL, but there are many dummies (~38 atm) involved in the projects that have trouble using TortoiseSVN when contributing, and very oftenly we had to fix messed up updates. Well, I think these two give the idea of what we've been trying to reach. So, is there a practical "individual" protection for our extensive data or my hope can already be euthanized? P.S.: Seriously, at the place where I live/work, political corruption gone the wildest, so denounce related options are likely impracticable. Yet both netadmins have strong "political bond" with the CEO and the President, hence their lousy behavior and our failed delation attempts.

  • backing up ntfs disk using rsync on ubuntu

    - by user70366
    For a long time I was using windows. I have a separate drive I use to keep copies of my media files, photos etc. on, which I periodically backup to an external drive. In Windows I used SyncToy to do this. After my Windows stopped booting, I decided to switch to Linux (Ubuntu 10.10). That seems to be going fine, but now I want to backup my drive to the external drive like before. Mostly the two drives will be already the same with maybe about 10GB of extra files added. So I try to use rsync to synchronise the two drives like this: rsync --dry-run -rvlt --modify-window=1 /media/Antonio1TB/Backup /media/FREECOM\ HDD/Backup The problem is the dry run indicates that every file on the drive will be copied. Not just the files I have recently added. What is the correct command to synch two NTFS drives under Ubuntu so that files that already exist don't get copied again? Thanks.

  • Disk controller speed responsible for slow write speeds?

    - by vizvayu
    I have question. I'm using ESXi 4.0U1 in an IBM x3200M2 with an integrated LSI 1064e RAID controller, without any kind of cache. I have 3 250GB HOT-SWAP SATA HDs configured in RAID1E (IME). ESXi works fine, read speed are quite OK, but write speeds are incredible slow, never more than 8MB/s, and this is the best case scenario, benchmarking with iozone streaming writes, using a VMWare Paravirtual controller and with only this VM active, no swapping of any kind (total vm memory reserved). Already wrote to IBM but I don't have any kind of pay support so they didn't even answered, so I'm just wondering... anybody has any experience with a similar setup? I just want to be sure this is hardware related and can't be fixed with some kind of config option, because I'm thinking on buying a new RAID controller (Adaptec 2405 looks nice). Thanks again!

  • Rescue data from damaged hard disk

    - by Lexsys
    Hello. I have a 500 GB hard drive with one NTFS-partition on it. I can mount it with Ubuntu and view the contents. But when I try to copy something, I get an I/O error. Ok, I tried to make its image with dd. I/O error as soon as it starts. I have installed ddrescue, but its manual page says not to use it with drives, failing on I/O. Can I manage to get some information from this drive and how to do this?

  • How do I know if my disks are being hit with too much IO reads or writes or both?

    - by Mark F
    Hi All, So I know a bit about disk I/O and bottlenecks relating to this especially when relating to databases. But how do I really know what the max IO numbers will be for my disks? What metric might be available to me for working out roughly (but needs to be a good approximation) of how much capacity (if you will) have I got left available in I/O. I've seen it before where things are bubbling along nicely and then all of a sudden, everything screams to a halt, and it ends up being an IO bound problem. Is there a better way to predict when IO is reaching its limits? This article was interesting but not giving the answer I desire. "http://serverfault.com/questions/61510/linux-how-can-i-see-whats-waiting-for-disk-io". So is my best bet surrounding just looking at 'CPU IO WAIT'? There must be a more reactive method for this? Best, M

  • Cloud storage services offering one-time download links? [closed]

    - by TARehman
    Is anyone aware of consumer-targeted cloud storage services that allow users to generate a one-time download link for hosted files? Case in point: I have an encrypted container with some documents I need to send to a vendor. I would prefer to give them a one-time download link, so that I know when they have accessed the file, and then inform them of the passphrase by phone. I have heard that MediaFire offers 1-time links, but that they are buried in tons of advertising. At the moment, I'm not sure that I consider MediaFire fully legitimate; I'm more interested in solutions with Google Drive, Box.net, DropBox, etc.

  • Disk Management

    - by Mars
    I'd like to know what's with all those unnamed drives. I've always thought they are what they say they are (recoveries and what not), why are there so many of them? and why do they all say 100% Free (i.e. they're all empty!). If that's the case, what happened to my recovery? Info: I'm on Dell Inspiron 7520 Windows 8 Single Language (Had Kali installed on SSD a couple of days ago, now I've just deleted that and will install Kali on VM on SSD, that's drive (S:).

  • Access denied to EFS encrypted files after PC joins domain

    - by mjmarsh
    I'm experiencing strange behavior with Windows Encrypted File System: I have a machine that is in workgroup mode (not joined to a domain) I encrypt an entire directory structure on the machine (basically a folder and subfolders with data files for my application). My application writes and reads files from the encrypted file hierarchy as a local Windows user (let's call the account 'SecureUser'). This works fine I then join the PC to a domain (Let's call it 'TEST') Afterwards, processes running as the local 'SecureUser' account can't read the files it wrote originally when it was off the domain (What is also strange is that the files are listed as "read only" now and I cannot unset this flag via Windows Explorer or the command line, even though it looks like it succeeds) I then 'un-join' the PC from the domain and everything works again Is there something about changing domain membership on a PC that changes the behavior of EFS so that previously encrypted files cannot be read, even by the originating user? Thanks in advance

  • Internal SATA hard disk shows up as removable device on Windows 7

    - by neutron80k
    I am running Windows 7 on an Acer Aspire M7720 with three internal SATA drives; drive #2 and #3 are on a removable HDD rack. Drive #3 (on the second removable HDD rack) shows up as removable device in the system tray. If I take drive #3 and put it in the first rack, it shows up as an internal drive. If I put any other drive in the second removable rack, that drive is also shown as removable device. I would like to fix that so that the drive in the second removable rack also is listed as internal drive. Since this seems to be independent of the actual drive in the rack, I checked the BIOS, but that third SATA port uses the same configuration as the second rack. So far, I could not find a solution for this problem (it's really more an annoyance than a problem), any ideas are welcome.

  • What is the easiest way to make a backup of an entire hard disk

    - by Solignis
    Hi there, I got myself a dell laptop from the local computer store. Its a used machine with Windows Vista Home Basic on it. I want to load Ubuntu Desktop 10.10 though so I can do perl development. BUT I want to keep a copy of the entire harddrive with the dell utility partition and Windows Vista in case I want to go back. I was thinking I could image the drive but I not sure what to use, I don't have Ghost or anything, Someone had told me about Clonezilla. Would that work for me? Is it hard to use? Also I want to burn the data to a DVD or something more storable than a harddisk.
