• How can access files on shared drive from Windows 2008 server configured with SFTP

  - by communicator

  I have installed OpenSSH on my windows 2008 server by following the user guide here . Now I have some files on windows network share with UNC path as \\corp\test\testdata I want map this file system on network share to my windows 2008 server which is configred with SFTP so that I can access these files from my Java Program by doing SFTP to windows 2008 server.Is there anyway I can map the network share to C or other drive in server so that all the files on the share will be available as local files on the server?

• Read access to Active Directory property (uSNCreated)

  - by Tom Ligda

  I have an issue with read access to the uSNCreated property when doing LDAP searches. If I do an LDAP search with a user that is a member of the Domain Admins group (UserA), I can see the uSNCreated property for every user. The problem is that if I do an LDAP search with a user (UserB) that is not a member of the Domain Admins group, I can see the uSNCreated property for some users (UserGroupA) and not for some users (UserGroupB). When I look at the users in UserGroupA and compare them to the users in UserGroupB, I see a crucial difference in the "Security" tab. The users in UserGroupA have the "Include inheritable permissions from this object's parent" unchecked. The users in UserGroupB have that option checked. I also noticed that the users in UserGroupA are users that were created earlier. The users in UserGroupB are users created recently. It's difficult to quantify, but I estimate the border between creation time between the users in UserGroupA and UserGroupB is about 6 months ago. What can cause the user creation to default to having that security property checked as opposed to unchecked? A while back (maybe around 6 months ago?) I changed the domain functional level from Windows Server 2003 to Windows Server 2008 R2. Would that have had this effect? (I can't exactly downgrade the domain functional level to test it out.) Is this security property actually the cause of the issue with read access to the uSNChanged property on LDAP searches? It seems correlated, but I'm not sure about causation. What I want in the end is for all authenticated users to have read access to the uSNCreated property for all users when doing an LDAP search. I would also be OK if I could grant read access for that property to an AD group. Then I can control access by adding members to the group.

• How to separate Hyper-V Private network from the External network

  - by Ron Ratzlaff

  I am setting up a virtual test lab and I configured a domain controller VM running Windows 2008 R2 on my Hyper-V 2008 R2 server. I needed to download and install updates on it so I added an External NIC adapter and got that done. However, systems on my actual real physical domain were pulling IPs from this server and that was a big oopsy on my part so I immediately removed the External NIC adapter until I could find out how to go about keeping the Private and the External separate. If someone from the Server Fault community can help with this since I am pretty new to this, I would be very grateful. Thanks everyone.

• Bring internet connection to ssh target machine via tunnel?

  - by Calvin

  I have a CentOS 5 machine deep inside firewalls that's only reachable via ssh on an unconventional port, let's say 98765. I normally connect to this machine like this: ssh -P 98765 user@ip -L5900:localhost:5900 I need to run yum to install some packages on this machine, but it's not possible since the outbound ports are all closed on this machine. I want to do something like this to "bring my internet connection" to this machine: ssh -P 98765 user@ip -L5900:localhost:5900 -R80:localhost:80 -R21:localhost:21 My intention is that, when I run yum on the machine, yum will use port 80 and 21 through my originating machine. Is something like this even possible?

• Setting up a vpn and IIS IP address restrictions

  - by carpat

  I'm trying to get a VPN set up with internal access only sites. I have set up a VPN on a windows server (single VPS server), and I can connect from a remote computer and I get an IP assigned correctly (from 192.168.1.1 - 255) Next I configured IIS (running on the same machine) IP Address and Domain Restrictions to only allow only IP address range 192.168.1.0 with subnet mask 255.255.255.0 When I connect to the VPN with "Use Default Gateway on Remote Network" (so that requests must go through the vpn), I get a 403 from the internal sites. What did I miss?

• Can't Connect To Local Mysql Using IP Address, but CAN connect from remote server

  - by user1782041

  Here's an interesting one that does not seem to fall into any of the mysql connection issues I've read about or searched for: On an Ubuntu 12.04 box I had some system updates waiting to install, and I took care of that this evening. After the install, I started seeing some errors in my syslog complaining about a particular php script that could no longer connect to the mysql instance on the box. Here is the specific error: PHP Warning: mysql_connect(): Can't connect to MySQL server on '192.168.0.40' (4) Now, the server's IP address is 192.168.0.40, and I've checked to make sure that I have mysql listening on 0.0.0.0 so that I can connect using either "localhost" or "192.168.0.40". Here's where things get odd: From the local machine, if I try the following: mysql -uroot -p -h192.168.0.40 I get this error: ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.0.40' (110) I've checked, and error 110 indicates an OS timeout, and error 2003 is the mysql generic "can't connect" error. This indicates that it is not permissions with the user. However, if I do the same thing from a remote machine (say, from 192.168.0.30), I log right in with no problems. Futher, other scripts on the local machine that connect to mysql using "localhost" for the host rather than "192.168.0.40" connect with no problems. Also, I can connect via the mysql socket with no problems both from the command line and php scripts. So, this feels like a networking issue of some kind on the local box, but there are no iptables rules on this box (it is firewalled externally) and I can't figure out what else may be causing this. This problematic script worked perfectly prior to the latest system update. For now, I'll simply change the script to connect via localhost, but I'd really like to know why it broke for 2 reasons: There may be other scripts that connect using 192.168.0.40 that don't run very often which are now broken. Auditing them all will take more time than I feel like devoting at the moment. I'm curious, and want to know why it broke so I can fix it correctly. Any help?

• Tomcat repeated 401 and the client nonce cache

  - by PaulNBN

  I've got a Tomcat 6.0.35 service with a SOAP based webapp protected by Digest Authentication. We are seeing issues with various users getting repeated 401 responses since we upgraded to 6.0.35. Additionally we are getting the following entries in Catalina log: WARNING: A valid entry has been removed from client nonce cache to make room for new entries. A replay attack is now possible. To prevent the possibility of replay attacks, reduce nonceValidity or increase cnonceCacheSize. Further warnings of this type will be suppressed for 5 minutes. Any idea what is going on?

• ISPConfig 3 SSL automatic rewrite

  - by lol

  I was wondering how you could get apache2 to redirect http://server.com:8080 to https://server.com:8080 - I have an ISPConfig 3 setup and the http://server.com:8080 virtual host currently prints a 400 back request error given that I've tried adding RewriteEngine on RewriteCond %{HTTPS} !^on$ [NC] RewriteRule . https://%{HTTP_HOST}:8080%{REQUEST_URI} [L] to the ispconfig.vhost file (and reloading the conf) with no success --edit!-- I've been playing around with it and adding an 'always redirect to google' into the ispconfig vhost and it works once you've already started talking ssl to it. this means the non-ssl connections are getting 'bad request errors' before the vhost is loaded... but where...? --edit 2!-- nope, the ssl is handled exclusively by the virtual host - if I turn off the ssl engine then the rewriting works perfectly (but obviously there is no ssl at https://) thanks!

• How to change MySQL data directory?

  - by Jonathan Frank

  I want to place my databases in another directory, so I can store them in an ESB (elastic block storage, just a fancy name for a virtualized harddisk) together with my web-apps and other persistent data. I have tried to walk through a tutorial at http://crashmag.net/change-the-default-mysql-data-directory-with-selinux-enabled. Everything seems fine until I type this command: # semanage fcontext -a -t mysqld_db_t "/srv/mysql(/.*)?" Then the command fails and tells me that mysqld_db_t is an invalid SELinux context even if the default MySQL data directory is labelled with this context. I am running Fedora 15 on Virtualbox (behaves like an ordinary x86-compatible box) and Amazon EC2 (based on Xen) so the tutorial should be compatible. It is also worth to mention that turning off SELinux globally or just for the MySQL process is not an option, because such a solution will decrease the security of the system if a hacker gains access to the system via the MySQL server. I have never seen this problem before I changed to the Redhat/Fedora architecture, so it could be a distribution specific issue. Any help is highly appreciated

• How can I get WAMP and a domain name to work on a non-standard port?

  - by David Murdoch

  I have read countless articles on setting up a domain on WAMP to listen on a port other than 80; none of them are working. I've got Windows Server 2008 (Standard) with IIS 7 installed and running on port 80 (and 443). I've got WAMP installed with the following configuration. Listen 81 ServerName sub.example.com:81 DocumentRoot "C:/Path/To/www" <Directory "C:/Path/To/www"> Options All MultiViews AllowOverride All # onlineoffline tag - don't remove Order Allow,Deny Allow from all </Directory> localhost:81 works with the above configuration but sub.example.com:81 does not. Just to make sure my firewall wasn't getting in the way I have disabled it completely. My sub.example.com domain is already pointing to my server and works on IIS on port 80. Also, if I disable IIS and change the Apache port from 81 to 80 it works. Yes, I am restarting Apache after each httpd.conf change. :-) I don't need any other domain (or sub domains [I don't even care about localhost]) configured which is why I'm not using a VirtualHost. Any ideas what is going on here? What could I be doing wrong? Update Changing Listen to 80 but keeping ServerName as sub.example.com:81 causes navigation to sub.example.com:80 to work; this just doesn't seem right to me. Could ServerName be ignoring the :port part somehow? netstat -a -n | find "TCP": >netstat -a -n | find "TCP" TCP 0.0.0.0:81 0.0.0.0:0 LISTENING TCP 0.0.0.0:135 0.0.0.0:0 LISTENING TCP 0.0.0.0:445 0.0.0.0:0 LISTENING TCP 0.0.0.0:912 0.0.0.0:0 LISTENING ...

• "Hide from exchange address lists" not working in Exchange 2007

  - by Abdullah

  Hiding a user by checking the "hide from exchange address lists" from exchange management console is not working. The user still shows up in GAL. When I ran Get-Mailbox -Identity _user_ | FL I got HiddenFromAddressListsEnabled : True So the check-box is working but the user still shows up. It's been over 3 weeks since hiding the user so it's not a time issue. This is what I have tried: Using Outlook in online mode Using OWA Regenerating GAL Un-checking then re-checking the "hide" check-box

• Vserver: secure mails from a hacked webservice

  - by lukas

  I plan to rent and setup a vServer with Debian xor CentOS. I know from my host, that the vServers are virtualized with linux-vserver. Assume there is a lighthttpd and some mail transfer agent running and we have to assure that if the lighthttpd will be hacked, the stored e-mails are not readable easily. For me, this sounds impossible but may I missed something or at least you guys can validate the impossibility... :) I think basically there are three obvious approaches. The first is to encrypt all the data. Nevertheless, the server would have to store the key somewhere so an attacker (w|c)ould figure that out. Secondly one could isolate the critical services like lighthttpd. Since I am not allowed to do 'mknod' or remount /dev in a linux-vserver, it is not possible to setup a nested vServer with lxc or similar techniques. The last approach would be to do a chroot but I am not sure if it would provide enough security. Further I have not tried yet, if I am able to do a chroot in a linux-vserver...? Thanks in advance!

• What are the licensing differences between Windows 8 Professional x64 fqc-05955 and fqc-05956?

  - by Razvan Panda

  If I do a search for Windows 8 Professional x64 in my country, the only version I can find is having the code fqc-05955 and is labeled OEM. If I perform same search on amazon.com, the only version I can find is having the code fqc-05956 and is labeled System Builder. There's not much information about licensing of Windows 8 that I could find. According to this article when using System Builder it can be transferred from one computer to another. What are the differences in licensing between those 2? Is fqc-05955 transferable from one hardware to another like System Builder is? Can I install fqc-05955 on a computer I already own that has no prior windows licensing? I am asking this, since many stores that sell fqc-05955 say it can only be bough with a computer. Thanks for your help!

• windows rename command to rename file.a.b to file.b

  - by sakibmoon

  I have a few folders with hundreds of html files. The file name should have been .htm but it is .asp.htm and it does not run. It is plain html file and there is no asp code. So, I tried to rename the files using rename command. I tried like this rename *.asp.htm *.htm But it does not work. After trying a few other combinations I believe rename or ren command can't change the double dot extension. The only change the last extension. So, if I try rename *.asp.htm *.asp.htm I thought nothing would be changed, but, the file name changes from file.asp.htm to file.asp.asp.htm I hope someone would help me with this. Another thing is, can I force apache to run files with .asp.htm extension? Currently it can't run those files. Thanks in advance.

• What is the best way to downscale mp4 video while keeping it as sharp as possible?

  - by Brandon Durham

  I've got an .mp4 file that's currently 830x1100 (it's a screencast) that I need to resize down to 114x150. I've been experimenting for hours with ffmpeg settings and nothing comes out looking nice and sharp. The original file looks decent, and I can't figure out why the downscaling makes it look so blurry. Unfortunately I can't share the video because it contains a walkthrough for software that hasn't yet been released.

• Windows 8 freezes after every other reboot on Lenovo W520 after about 10 seconds

  - by John Nevermore

  I have a Lenovo W520 laptop with i7-2760QM, intel 520 SSD and Nvidia Quadro 1000m. When i boot the PC with discrete graphics SET in BIOS, the computer totally freezes and the only thing left to do is reboot. This only happens with NVidia drivers for Windows 8 x64 installed (I've tried about 4 different drivers on Nvidia's site). When i boot the PC with integrated graphics set in BIOS, there is a momentary "hickup" after about 10 seconds (instead of freezing) and then everything is working fine. When i boot the PC with discrete graphics ON and no Nvidia drivers installed, the same thing happens as described above with integrated graphics. I've tried doing 1) bcdedit /set disabledynamictick yes 2) Disabling VT-x in BIOS (Seriously would prefer not to disable it, since i use VM-s almost every day) but no dice. The only thing that worked was to enable the Hyper-v feature. I was then able to boot properly with discrete graphics and Nvidia drivers installed, but since i use VMWare for VM development this was no solution (VMWare complained about not being able to launch because of Hyper-v being installed). I followed the instructions in this tutorial, to be able to run VMWare. Then the computer just booted into a black screen past Windows logo. How to boot Windows 8 x64 without freezing with Quadro 1000M enabled, Nvidia Drivers installed and Hyper-v feature preferably disabled ?

• Force the computer to always use current display settings

  - by sazpaz

  So I'm having a terrible black screen problem with my new installation of Windows 8. The screen basically goes to black every time I turn it on or sleep, or connect to an external or monitor. I dont really know what steps actually cause the problem and cant seem to figure what steps allow the screen to come back, besides forcing restarts, going to sleep and waking up, and smashing Win + P. I have a strong feeling it's because the Switchable graphics I have (Intel HD + Radeon 5060), so I'm looking for a way to make the computer always use a specified mode (i.e the current mode I'm on, that does show stuff on the screen) and force it to use it everytime? Any ideas? EDIT: I've Installed all the latest drivers I've found. Tried most of the solutions around the web for this problem. Updated the BIOS to UEFI (from HP Support Assistant), etc. Laptop is an HP- Envy 14

• Transfer Books from Mac to Kindle App on the Nexus 7

  - by AJ.

  I have some e-books that I've downloaded from Project Gutenberg and some other sources to my MBP. They are all DRM free. Excluding e-mail them to my Kindle as a personal document as a method (the total size is more than 5 GB, the space provided by Amazon), is there any way to transfer these books to my Kindle App on my Nexus 7 (Android Tablet). I have the Kindle App version 3.1.7 I've already seen the question Can I sync books I didn't buy from Amazon via Kindle app? but that is not the answer I'm looking for. Thanks

• Windows 7 / 8 tool for amplifying sound / equivalent to pavucontrol?

  - by Quandary

  I'm watching live streamed videos, but the volume sometimes is barely loud enough. With Windows, I can only turn the system volume and the flash volume up to maximum, and then bad luck if that's still not loud enough. On Linux, on the same notebook, I have the same problem, but I can use pavucontrol to amplify the sound volume beyond 100%. Unfortunately, I can't always work on Linux, since Visual Studio and SQL-Server only run on Windows. Is there any tool or way to amplify volume on Windows 7 / 8 , without having to resort to run Linux in a virtual machine?

• Mapped networkdrive on logout

  - by Robuust

  I'm using a script to keep a mapped networkconnection alive, but ofcourse the mapped connection is gone when I logout. The point is now, that I'm running this on Windows Server 2008 R2, where I use remote desktop to login on the administrator account. However, it should remain logged in and not remove the mapped connection as this script takes care of not logging out on MS office 365 sharepoint. Is there a way to keep the mapped networklocation (L:) available after logout? So the script can run to remain the connection? # Create an IE Object and navigate to my SharePoint Site $ie = New-Object -ComObject InternetExplorer.Application $ie.navigate('https://xxx.sharepoint.com/') # Don't need the object anymore, so let's close it to free up some memory $ie.Quit() # Just in case there was a problem with the web client service # I am going to stop and start it, you could potentially remove this # part if you want.

• Can a Windows PC do anything while it is sleeping?

  - by Root

  I heard that OS X Mountain Lion on a Mac has a feature called Power Nap : With Power Nap, your Mac sleeps but your applications stay up to date. So you have the latest information — such as mail, notes, reminders, and messages — when your Mac wakes up. Power Nap performs Time Machine backups to Time Capsule and downloads OS X software updates while your Mac sleeps, so you can begin installing as soon as you wake it up. Can Windows do the same on a PC?

• USB transfer speed "logarithmically" decreases. Why and can it be improved?

  - by starship

  I have an external hard drive. Just today I tried to copy a bigger file (it was film of ~230 MB) and at first it rushed up until ~70%. There is started decreasing. At first it started at around 56 MB/s Then it rapidly dropped to 23 MB/s (File transfer was 70% complete) Then it slowly started decreasing until it was around 2 MB/s (File was ~90% complete) When it finished the transfer it was slightly above 1.5 MB/s. To describe it graphically: If you drew a curve of the decrease it would probably resemble the graph of a logarithm function So, what I'm really asking is: "Why does this happen?" and "Is there a way around it?" Thank you!

• How do I create a VBA macro that will copy data from an entry sheet, into a summary sheet by date

  - by Mukkman

  I'm trying to create a macro that will copy data from a data entry sheet into a summary sheet. The entry sheet is going to be cleared daily so I can't use a formula just to reference it. I want the user to be able to enter a date, run a macro, and have the macro copy the data from the entry sheet into the cells for the corresponding date on the summary sheet. I've looked around and found bits and pieces of how to do this but I can't put it all together. Update: Thanks to the information below I was able to find some additional data. I have a pretty crude macro that works if the user manually selects the correct cell. Now I just need to figure out how to automatically select the current cell relative to the current date. Sub Update_Deposits() ' ' Update_Deposits Macro ' Dim selectedDate As String Dim rangeFound As Range selectedDate = Sheets("Summary Sheet").Range("F3") Set rangeFound = Sheets("Deposits").Cells.Find(CDate(selectedDate)) Dim Total1 As Double Dim Total2 As Double Dim Total3 As Double Dim Total4 As Double Dim Total5 As Double Total1 = Sheets("Summary Sheet").Range("E6") Total2 = Sheets("Summary Sheet").Range("E7") Total3 = Sheets("Summary Sheet").Range("E8") Total4 = Sheets("Summary Sheet").Range("E9") Total5 = Sheets("Summary Sheet").Range("E10") If Not (rangeFound Is Nothing) Then rangeFound.Offset(0, 2) = Total1 rangeFound.Offset(0, 3) = Total2 rangeFound.Offset(0, 4) = Total3 rangeFound.Offset(0, 6) = Total4 rangeFound.Offset(0, 7) = Total5 End If ' End Sub This version will find the first value on the page and fill in values: Sub Update_Deposits() ' ' Update_Deposits Macro ' Dim selectedDate As String Dim rangeFound As Range selectedDate = Sheets("Summary Sheet").Range("F3") Set rangeFound = Sheets("Deposits").Cells.Find(CDate(selectedDate)) Dim Total1 As Double Dim Total2 As Double Dim Total3 As Double Dim Total4 As Double Dim Total5 As Double Total1 = Sheets("Summary Sheet").Range("E6") Total2 = Sheets("Summary Sheet").Range("E7") Total3 = Sheets("Summary Sheet").Range("E8") Total4 = Sheets("Summary Sheet").Range("E9") Total5 = Sheets("Summary Sheet").Range("E10") If Not (rangeFound Is Nothing) Then rangeFound.Offset(0, 2) = Total1 rangeFound.Offset(0, 3) = Total2 rangeFound.Offset(0, 4) = Total3 rangeFound.Offset(0, 6) = Total4 rangeFound.Offset(0, 7) = Total5 End If ' End Sub
