• SElinux stopping LVS from working with https

  - by J Hoskins

  LVS/piranha is setup and trying to get it to balance https instead of http. Setup https testing with wget - idea from this link. Works when I do it at the command prompt. With SELinux enforcing, the wget fails to run due to the lack of access to /dev/random. (Error - Could not seed PRNG; consider using --random-file. Disabling SSL due to encountered errors.) wget runs as system_u:system_r:piranha_lvs_t:s0 but the file/device /dev/random has system_u:object_r:random_device_t:s0 Also, wget is trying to getattr and read. How do you allow wget to use /dev/random so it will do ssl?

• Everything Windows Explorer does hangs up t some time or another

  - by William Barnes

  Yes this is a duplicate of something I have tried to ask in the past. I think I am posting wrong since my first question was deleted OK I ran SCANNOW nd it came back with no problems. I booted in Safe mode and windows evplorer worked OK. I am not sure what that proves. I also ran AUTRUNS and disabled everything that you said, but it still dies. I read someplace that it could be a service program, but I can't find that link anymore. Something about shutting off all non-windows SP's and then start adding back SP's until it quits. The problem is that sometimes it will work, but most of the time it does not. Makes saving or retrieving anything impossible. SAVEAS hangs up, my Garmin Map updater hangs up etc.. I was having this problem before installing Garmin so I am reasonably sure it is not the problem HELP PLEASE, I don't have many brain cells left and can't afford to lose more.

• How to modify PATH variable for X11 during log-in?

  - by user1028435

  Original question is here: Overwriting "Print Screen" actions in linux without administrative rights. Decided to revise my question, based on what I learned there: Essentially, my problem is that I am working on some lab computers (read: no administrative rights) that, if I log in, I need to change the PATH variable as X11 starts. The reason is that I need to change the PATH variable at this time, as opposed to later, is that the Print Screen command seems to "bind" during login (forgive my bad explanation of this). You can see in the work-around I listed in the previous section, that I can make it work by starting a new X, but I was wondering if it is possible to change upon login. Any ideas?

• Change from IDE to AHCI after installing Windows 8

  - by Louis

  I had my drive controller configured for IDE when I installed Windows 7. This didn't change when I upgraded to Windows 8. I now need to enable AHCI, but doing so causes Windows to fail to start. It doesn't know how to automatically fix the problem. I was able to use Regedit from the recovery area, in order to try using this fix that worked for Vista. That key is missing in Windows 8, however. I read that the relevant key is now in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci. But my settings already match the changes they suggest making. How can I get Windows to boot after enabling AHCI in the BIOS?

• Can't uninstall SBS 2003 in sbs 2003 -> sbs 2008 migration

  - by ChrisMuench

  I'm trying to remove sbs from my sbs 2003 server. Also I'm logged in as Administrator. However When I start to go through the wizard it gives me the following error. You must be a member of the Domain Admins, Schema Admins, and Enterprise Admins group. I then did some research and found this (http://support.microsoft.com/kb/842694) and I came to the point where it says to delete the server from Sites and Services. However when I clicked delete it wanted me to dcpromo the box first. However I have read you have to uninstall exchange first and then dcpromo it to remove AD. Any ideas?

• How to get better video quality in Lync?

  - by sinned

  I want to use a ConferenceCam from Logitech to stream talks live via Lync. When I view the RAW webcam image via VLC, the quality is very good (but the latency is high because of buffering). However, when I stream it using Lync, the video gets blurry. Is there a way to ensure QoS in Lync or otherwise improve the video quality to (near-)native? I would rather have some dropped frames than a lower resolution where I can't read the slides. In my setup, I use Lync with an Office365-E3 contract, so I have no Lync-Server in my network. I thought about replacing Lync completely with VLC, but I first want to try Lync because VLC will probably cause firewall issues. Also, I haven't looked up the VLC parameters for less buffering, faster encoding, a bit lower resolution (natively it's more than HD) and streaming.

• How to prevent yourself from commenting on websites?

  - by MHH

  There is a bunch of browser add ons to either block particular websites (i.e. leechblock, chrome nanny or various OS specific solutions) or block the comment section of a website (i.e. commentBlocker). However, what if you want to be able to read the comment section of all websites, but want to never be able to add comments yourself, on particular sites? Is there anything that will allow this? I'm particularly interested in answers that will work for both windows and mac, and will also work for google chrome, firefox, and safari (note they can be different solutions for each browser/operating system)

• Which Single Source Publishing tools and strategies are available?

  - by Another Registered User

  I'm about to write a 1000-Pages Documentation about a huge programming framework. The goal is to bring this documentation online into an web platform, so that online users can search through it and read it online. At the same time, the text has to be made public in PDF format for download. And at the same time, the whole thing needs to go into a printed book as well (print on demand, they want a giant PDF file with the whole book). The PDF files: The whole content is divided into several chapters. Every chapter will be available as a standalone PDF eBook. And finally, all chapters will be available in one huge printed book. Is LaTeX capable for something like that? Can it be used for Single Source Publishing? Or would I have to take a look at other technologies like DocBook, etc.?

• Use pt-table-sync to setup a new MySQL DB

  - by Generation D Systems

  I have 2 hosts (A and B). B contains a MySQL server with a database called mydb, and A contains a MySQL server with nothing (fresh install). I want to replicate the entire mydb from B to A, by running a script on A (I do not have shell access to B). Can I run this on A: pt-table-sync --execute h=b.mydomain.com,D=mydb h=a.mydomain.com I've read the docs but don't get a 100% comfort feeling (perhaps because of all the warnings about damaging your data if you don't know what you're doing). Will this work? as well, is h=a.mydomin.com necessary? (Will it route all traffic back in/out the local NIC?) can I use localhost or nothing at all?

• Best MTA setup for home or laptop computers - not server

  - by thomasrutter

  Hello, What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that connects to various different wifi networks? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they have a static IP have a domain name are always connected to the same network My requirements are, I guess: Ability to forward mail for "root" to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

• Good Books About Scaling Up Databases/Servers/etc.?

  - by Mehrdad

  I've applied for an internship at a startup company that expects its user base to grow by a large factor in a small amount of time, and so part of their project is to scale everything up so that they're ready: handling more/larger requests efficiently, handling server failures, load balancing, getting more JavaScript to run faster on the client computers, etc. Part of my job will also be figuring out what to do, so it's not obvious what my exact task will be at the moment. I was told that I should start reading up a little more about this so that I would have a little bit of an idea of what to do. What are some good books for me to read on this topic? I have a little bit of experience with the usage of MySQL (and also a little experience with web development), but in no way do I claim any knowledge on the internal workings of databases or distributed systems, so I might need readings more on the introductory side.

• Why subnet mask for IP 10.0.1.4 is 255.255.255.0?

  - by Rohit Kandhal

  Well I'm not sure whether I'm missing something here. But all I've read is that if first octet of IP is within 0 - 127 then it is categorized as Class A subnet and correspondingly Subnet Mask for this is 255.0.0.0 but when I connect my system to Apple airport then my system gets IP as 10.0.1.4 however subnet mask is 255.255.255.0 not 255.0.0.0. Please explain what I'm missing here. If there is something like for apple router subnet mask is calculated on some different flags then please let me know.

• How to copy text from Java program?

  - by Mohd. Ismail

  I am using one Java program called JDownloader v0.9.581 and want to copy full file and link list from main scrolling window. JDownloader is not having any way to save full list as text file. I am already trying all programs from Is there any way a user can view or copy non-editable GUI controls' contents at runtime? and Read the contents of a ComboBox (or any other windows control) and also many other programs from Google like GetWindowText. But nothing is allowing me to copy full text from a Java program like this. Someone is telling me - do printscreen and OCR - but that is not good way for me. How I can copy full text from JDownloader?

• Internal only DNS?

  - by ethrbunny

  We are running a research project with hundreds (becoming thousands) of remote hosts. Each host is running OpenVPN so we can find them regardless of what their 'assigned' IP is. We have been using DynDNS to manage this but we're running into some issues with them ( API is weak/nonexistent, size constraints, etc). Im looking into setting up a internal-only domain (EG "our.stuff" so a host would be "site1.our.stuff" or "site3.net4.our.stuff") that I can configure with the info from the OpenVPN server. Since we'd have to point our internal DNS to this machine it would have to be able to route/cache requests for 'external' machines as well. I've been trying to read about 'internal DNS', 'private', 'non-routeable' but I'm not having much success. Summary: need info on internal, caching DNS server. Something with open-source would be ideal. If not, I can script out changes to .conf, etc.

• psloggedon timeout question

  - by user60707

  I have a list of machine names from my network that I have put in a batchfile to run through the list and show me who is logged onto each. psloggedon \machineA psloggedon \machineB psloggedon \machineC psloggedon \machineD psloggedon \machineE psloggedon \machineF Psloggedon works fine, however when it hits a machine that isnt actually on the network, it hangs for a good 30 - 60 seconds before moving onto the next machine...I was just wondering if there was any way to speed this up so that if it hits a machine that isnt on the network, it moves onto the next machine in the list much quicker. I have read in other places that this could be possible by adding a ping -n loop into the command but im not sure how to get that to work? any ideas guys? Many thanks in advance. Jimmy

• How can I tell what user account is being used by a service to access a network share on a Windows 2008 server?

  - by Mike B

  I've got a third-party app/service running on a Windows 2003 SP2 server that is trying to fetch something from a network share on Windows 2008 box. Both boxes are members of an AD domain. For some reason, the app is complaining about having insufficient permissions to read/write to the store. The app itself doesn't have any special options for acting on the authority of another user account. It just asks for a UNC path. The service is running with a "log on as" setting of Local System account. I'd like to confirm what account it's using when trying to communicate with the network share. Conversely, I'd also like more details on if/why it's being rejected by the Windows 2008 network share. Are there server-side logs on 2008 that could tell me exactly why a connection attempt to a share was rejected?

• MySQL query (over SSL) fails in IIS 7 using default AppPool identity

  - by Jon Tackabury

  I am trying to run a website locally in Windows 7 under IIS 7. I have the AppPool configured to use "Classic" mode, but connecting to a MySQL DB that requires SSL fails. If I change the identity to my user account it works perfectly. It fails when using the default "ApplicationPoolIdentity" account. Is there something I'm missing somewhere? Why would running a MySQL query over SSL fail for certain user accounts? Update: This is the exception that the MySQL Connector is throwing: "Reading from the stream has failed. Attempted to read past the end of the stream."

• Connecting to Exchange Server 2003 over POP using openssl s_client

  - by Andreas Jansson

  Hi, I'm trying to fetch emails programmatically from Exchange 2003 over POP. As a proof of concept I'm trying to connect using openssl s_client. I've started the POP service on my Exchange server. Trying to connect using openssl s_client -connect MYEXCHANGESERVER:995 returns 20303:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188: Trying openssl s_client -connect MYEXCHANGESERVER:995 -starttls pop3 returns CONNECTED(00000003) write:errno=32 Forgive a newb - I'm basically shooting wildly in the dark with no idea on what I'm supposed to be doing. In the past I've read my GMail over openssl s_client, and setting up those certificates was easy and well documented. I would imagine I need to set up some sort of certificate here as well, and I've looked a bit at using a .pfx file. But like I said, I'm completely lost here. Thankful for any advice, Andreas

• Performance problem with Win Server 2008 at vbox on Ubuntu 9.10 Server

  - by Diskilla

  Hey, i´ve got an Ubuntu 9.10 Server and tried to install Windows Server 2008 in a virtual machine. The Problem is, the Server has got 8 cores, but the virtual machine seems to have problems with that. The VM is very slow and not really usable if i set the VM-config to more than one core. Is it set to only one core everything works fine, but thats not a solution because I bought the Server with several cores for a reason... Does anybody know this problem or has got a solution? I feel like I read the entire internet via Google... no solution found. Greetz Diskilla P.S.: I´m from Germany and it´s kind of hard to ask in english :-) I hope I din´t make that much mistakes.

• How do I access a shared folder using credentials other than the ones I logged in with?

  - by George Sealy

  I have a lab full of Windows 7 machines, and a shared login (user360) that all my students use. I also have a shared folder that they can all have read/write access to (for moving files around easily). My problem is that I also want to be able to create a shared folder for each student for submitting assignments. I can set up a shared folder with permissions for just a single user, and not the 'user360' account. The problem is, when I'm logged in as user360, and I try to open the 'StudentA', Windows never asks me for alternate credentials, it just refuses access because the user360 account is not allowed access. Can anyone suggest a fix for this?

• Where default settings are stored after applying GPO?

  - by tester5566

  When I apply a GPO that changes Service startup settings, where the default service startup settings are kept? And how can I read and modify them? The reason of the question is that I have a hundred of servers where most of services are disabled by a baseline GPO for hardening purposes. I want to relax this GPO by removing some services but I do not want that the service startup settings becomes default ones after the GPO is relaxed. So I want to keep the actual hardened state as a default state but allow local admins to change it if necessary. Thank you

• transaction log shipping sql server 2005 to 2008

  - by Andrew Jahn

  I have a reporting setup with SSRS on our sql server 2005 database. Because sql server 2008 is not supported by the main program which populates our database we are stuck with 2005 on our prod database. Unfortunately when I run our weekly check reports the web interface constantly times out because the server cant do the conversion to PDF. I've read that sql server 2008's SSRS is ALOT better with memory management. I was wondering if I can do some kind transact log shipping subscription publication from 2005 to 2008? Am I chasing a dream here. Currently I have to open up the ssrs project in visual studio and run the reports inside because it doesn't ever time out when doing the pdf conversion, only times out if I try to run it through the ssis web interface.

• Why is a ZFS pool not persisting over server restart?

  - by Chance

  I have a ZFS pool with 4 drives. It also has a 3gb ZIL and a 20GB L2ARC that are each partitions on an SDD that doubles as my Linux Mint (ver. 13) boot drive. The pool is mounted to /data. The problem I am running into is that when I restart the server the pool/directory is completely wiped despite having data in it prior. I'm afraid I'm doing something wrong in the setup, which leads me to the following questions: What would cause this? Is there anyway to get the data back? How do I stop it from happening in the future? Thank you in advance! pool: data state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0 raidz2-0 ONLINE 0 0 0 sda1 ONLINE 0 0 0 sdb1 ONLINE 0 0 0 sdc1 ONLINE 0 0 0 sdd1 ONLINE 0 0 0 logs sde4 ONLINE 0 0 0 cache sde3 ONLINE 0 0 0 errors: No known data errors

• IIS 7.5 default permission - is restriction needed?

  - by Caroline Beltran

  I am using IIS 7.5 and I do not need to explicitly specify permissions for my ISAPI application to execute. Additionally, the application can create subdirectories, create and delete files without me specifying permissions. Since I am using the default permissions, checked to see if web.config was safe from prying eyes over the web, and it can’t be read which is good. My app also creates some .log and .ini files which are also not viewable over the web. I did notice that .txt files are viewable. I really don’t know how default permissions allow my app to do so much. Is this safe or do I need to lock down? To be honest, I don’t know what accounts to restrict. App details: My ISAPI has an ‘allowed’ entry in ISAPI and CGI Restrictions Folder and subfolders containing my application has ‘default’ permissions set. Application pool is using ‘classic’ pipeline mode and no managed code. Pass-through authentication in use. Thank you for your time
