• Converting a Windows 2003 server

  - by Jim Bass

  We have a legacy database system based upon MS SQL running on Windows Server 2003. The client software will only run on Windows XP. We have recently had success converting a client into a virtual machine and running it under Fusion on Mac minis. So far, it is working incredibly well. So well, in fact, that we are now considering trying to convert the server to a virtual machine. This raises several questions, though: 1. The server uses a raid array. Does the VM virtualize the raid array? I only ask because in my experience Windows products don't like it when you change core hardware. 2. Is there any reason why running SQL server on a virtual machine won't work? It will be up 24/7. 3. Is there a different converter for servers? 4. Will I have to track down the licensing for MS SQL and Server 2003 or will they come across ok? 5. The company that designed the software is no longer in business. There is some fear that the software is somehow tied to the hardware configuration. We bought the hardware, but their engineers came out and configured the system. Will the virtual machine be able to spoof particular chip sets? Thanks! Jim Bass

• Where should my application setup put the binary executables in Windows 7?

  - by KeyboardMonkey

  I created a small Windows app, and am builder a setup for it using NSIS, but what I can't find out is where to put the executables to conform to the new Windows security model. Traditionally we put program files in, well, "c:\program files". With the security model getting more mangled with each Windows version, some users have restricted accounts, and I'm not sure installing into program files will work for these users. Where can I install my program's files that will cater for these lower-privileged users? Oh and I want to avoid ClickOnce.

  I'm trying to install under RVM the Ruby Enterpise (REE) under debian My debian is squeeze (uname -r) 2.6.18-194.26.1.el5.028stab070.14xen i did try to install ree but it complains that it is missing libssl-dev and libreadline5-dev.

The operational system is already updated and upgraded sources.list: deb http://ftp.de.debian.org/debian/ squeeze main contrib non-free deb-src http://ftp.de.debian.org/debian/ squeeze main contrib non-free deb http://security.debian.org/ squeeze/updates main deb-src http://security.debian.org/ squeeze/updates main I did try to install it using the following command: apt-get install libssl-dev libreadline5-dev But unfortunately i'm getting the following problems: The following packages have unmet dependencies: libreadline5-dev: Depends: libncurses5-dev but it is not going to be installed libssl-dev: Depends: libssl0.9.8 (= 0.9.8o-4squeeze1) but 0.9.8o-6 is to be installed E: Broken packages I was thinking to reinstall those packages and install again, but it has too many dependencies, and it is a production server, that i would like to know if there is any other way to fix it. Or at least to double check if it is necessary to reinstall both :-/

• Mcafee Auto-update from UNC path problem

  - by Vicky

  I have a network with 50 computers with no internet access. So instead of updating in each of them using dat file individually I tried to create a shared folder in server, and created a UNC in site repository. I downloaded the file DAT Package For Use with Mcafee AutoUpdate Architect & ePO 3.0 from http://www.mcafee.com/apps/downloads/security-updates/security-updates.aspx. When I try to update it is giving an error Error occurred while downloading file SiteStat.xml. So how fix it?

• LDAP groups not applying to filesystem permissions

  - by BeepDog

  System is ArchLinux, and I'm using nss-pam-ldapd (0.8.13-4) to connect myself to ldap. I've got my users and some groups in LDAP: [root@kain tmp]# getent group <localgroups snipped> dkowis:*:10000: mp3s:*:15000:rkowis,dkowis music:*:15002:rkowis,dkowis video:*:15003:transmission,rkowis,dkowis,sickbeard software:*:15004:rkowis,dkowis pictures:*:15005:rkowis,dkowis budget:*:15006:rkowis,dkowis rkowis:*:10001: And I have some directories that are setgid video so that the video group stays, and they're configured g=rwx so that members of the video group can write to them: [root@kain video]# ls -ld /srv/video drwxrwxr-x 8 root video 208 Oct 19 20:49 /srv/video However, members of that group, say dkowis cannot write into that directory: [root@kain video]# groups dkowis mp3s music video software pictures dkowis Total number of groups that dkowis is in is like 7, I redacted a few here. [dkowis@kain wat]$ cd /srv/video [dkowis@kain video]$ touch something touch: cannot touch 'something': Permission denied [dkowis@kain video]$ groups dkowis mp3s music video software pictures I'm at a loss as to why my groups show up in getent groups, but my filesystem permissions are not being respected. I've tried making a new directory in /tmp and setting it's group permissions to rwx, and then trying to write a file in there, it doesn't work. The only time it does work is if I open it wide up allowing o=rwx. That's obviously not what I want, and I'm not able to figure out what my missing piece is. Thanks in advance.

• Taking stock of an existing ASA Firewall

  - by Nate

  Imagine you are given an existing network using an ASA firewall. The network works, but you aren't sure of anything else. The firewall may be completely improperly configured, with "outside" actually being inside and "inside" actually being outside, for all you know. My question is this: what are the commands to take stock of an existing ASA firewall setup? With only CLI access, how do I figure out: What interfaces are available The names of the interfaces The security levels attached to the interfaces The access-lists attached to the interfaces, including rules and directions I know how to set these things (interface, nameif, security-level, and access-list/access-group), but I don't know how to figure them out given an existing system. On a related note, is there anything else that I should worry about checking to make sure that the network isn't wide open? Thanks!

• Problem running application on windows server 2008 instance using amazon ec2 service and WAMP

  - by Siddharth

  I have a basic (small type) windows server 2008 instance running on amazon ec2. I've installed WAMP server on to it, and have also loaded my application. I did this using Remote desktop Connection from my windows machine. I'm able to run my application locally on the instance, however when I try to access it using the public DNS given to it by amazon, from my browser, I'm unable to do so. My instance has a security group that is configured to allow HTTP, HTTPS, RDP, SSH and SMTP requests on different ports. In fact I have the exact same security group as the one used in this blog, http://howto.opml.org/dave/ec2/ I did almost everything same as the blog, except for using a different Amazon Machine Image. This is my first time using amazon ec2, and i can't figure out what I'm doing wrong here

• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  Hi Geeks, I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• Can't start firewall or automatic updates in Windows XP

  - by Chris Porter

  On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out. I've tried the suggestions below and many others: http://windowsxp.mvps.org/sharedaccess.htm http://support.Microsoft.com/kb/892199 http://windowsxp.mvps.org/repairwmi.htm I can't do a repair install because the installer doesn't detect existing versions. It's XP pro service pack 3.

• No blocked ports on internal interface of ASA

  - by blsub6

  I have a cisco ASA 5505 with three interfaces: Internal (100), DMZ (50) and External (0). The internal has a IPSEC VPN tunnel to my internal network I couldn't log in to my domain because of all of the port restrictions and such. I tried monitoring the traffic through the interface, seeing what it's blocking and then unblocking those ports but even then it didn't work completely correctly I finally just added a rule to permit any ip traffic from any network to any network on the internal interface and, of course, it worked fine But is that good security practice? Should I be blocking ports on an interface that's internal and over a VPN with the highest security level?

• Creating an app shortcut in Windows 7 XP Mode

  - by MT_Head

  I have a VERY old legacy app that I've managed to move from machine to machine; the installer for it doesn't actually work under newer versions of Windows, but I was able to track down the registry changes and DLL registrations necessary to make it work. I'm able to create a desktop icon in my XP mode environment, and the program works... but I'd like to add an icon to the Windows 7 menu, and run the program in semi-native mode. For example, the icon for Microsoft Security Essentials in XP mode has the following target: %SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\VMCPropertyHandler.dll,LaunchVMSal "Windows XP Mode" "||232f633" "Microsoft Security Essentials" Now, the only part of that that seems to be "magic" is "||232f633" - does anyone have any idea where that comes from, or how to identify the correct equivalent for an arbitrary program? I gather that, had the program been installed normally through a .msi file (or WISE, or NSIS, or what have you), this id would have been generated automagically... Thanks for any insights!

• High-performance Academic Server [closed]

  - by PHPsmith

  Suppose I want to build a server for the university's academic interests. The server is dedicated only to a site, where users (students and lecturers) just view and fill the academic data. But at a time (e.g. once a semester), about 12,000 students will access the site simultaneously. Due to limitation of resources, I have to build the server using free software (except for the operating system Windows 7, the university has been prepared). The hardware is also limited to the usual 4-core computers (eg, Ivy Bridge Intel Core i7-3770) with approximately 16GB of memory (DDR3 1600 MHz), equipped with an RJ-45 port (Intel 82 579 Gigabit Ethernet). With all these limitations, I have to choose the software (web server, database, etc) are appropriate for this purpose is achieved. I decided to create a site in PHP. Please help me by answering the following questions based on your expertise. (my prime candidate software to consider after googling) Web server which is faster & stable & secure, when implemented and optimized for PHP? And why? (nginx) PHP accelerator which is faster & stable & compatible with the selected web server? And why? (APC with Zend Optimizer+) Database which is faster & stable & secure, when implemented and optimized for selected web server and selected PHP accelerator? (MySQL) Are there any errors that have been or will be happening from my condition is? If there is, please enlighten me? Is there anything else I need to know in order to achieve this goal? If there is, please enlighten me? I understand that the performance also depends on the implementation of source-code program, so I assume it will create a site with the best efficiency (e.g. using AJAX).

• List existing file server permission groups/users

  - by Patrick

  So we have taken over a new client and their existing file server is frankly a mess. We have migrated their old file server from a 2k box to a 2k8 DFS cluster and now I'm looking at rebuilding both the folder structure and their permissions. Unfortunately its been half done with AD groups (poorly named/no description/notes) and half with individuals named in security on the folders themselves. What I'm looking to do is to dump a complete list of all the folders with their security permissions (ideally I'd like to ignore files but not essential). CACLS got me half way there but fails with an odd error message and its output isn't particularly user friendly and I'm working with roughly 2Tb/250,000 files here so I really need something that gives me a bit more functionality. Question : does anyone have any experience of something similar/know of a bit of software that might help me out?

• How do I securely store and manage 180 passwords?

  - by Sammy

  I have about 180 passwords for different websites and web services. They are all stored in one single password protected Excel document. As the list gets longer I am more and more concerned about its security. Just how secure, or should I say insecure, is a password protected Excel document? What's the best practice for storing this many passwords in a secure and easy manageable way? I find the Excel method to be easy enough, but I am concerned about the security aspect.

• Cannot SSH anymore, what went wrong?

  - by lbwtz2

  I use to ssh to a remote server (no rsa-key, just password). Now the server do not accept the connection any more and throw me this error: ssh_exchange_identification: Connection closed by remote host While I can google a little to find a fix I can't figure out what went wrong since I haven't touched anything on the machine since last login. Can you help me find the cause?

• Private VOIP network

  - by SuppositoryPlacebo

  I own a small private security services business. Some of my clients require 2-10 security officers per location. I'm trying to think outside the box in order to solve my communications problem. I'd rather not buy or lease hf radios or voip systems at the current rates. I'm wondering if there is an existing system, or if is at all possible, to setup a private communications network using only a server and bluetooth devices or a wifi/bluethooth combination. http://25.media.tumblr.com/tumblr_m44f0pn7BL1rwp6tgo1_1280.png I don't need "radio" per se. I just need a simple, private voip network. Is there an existing device that consists of nothing more than a wifi adapter to control a bluetooth device?

• Convert SQL Query results to Active Directory Groups

  - by antgiant

  Are there any quality products (ideally open source) that allow me to run an arbitrary SQL query that results in 2 columns (username, group name) and they adds that username in AD to a group of that name in AD? If the username doesn't exist it is ignored. If the group name doesn't exist ideally it gets created. Updated for Clarity: I have a MSSQL based system that is the authoritative source for some of the Active Directory Security groups, and their members. I want to be able to to have those Active Directory Security Groups populated by a one-way sync originating from MSSQL. Sadly the MSSQL based system does not have a good API, so I will have to do this with direct SQL calls. Is there anything that does this well?

• Local user vs. domain user? What is the right way here?

  - by ebeeb

  I'm a software developer in a company with 6 employees. Everyone has a machine for him-/herself, so none of the machines is shared. I'm currently setting up my machine with Windows 8 and was experimenting a bit with domain and local user accounts. Correct me please if I'm wrong, but I think the idea behind is, that domain users generally should not be able to modify the configuration of a machine (like installing software), since they are able to login on every single machine in the domain. The local user (usually just one local administrator per machine) is the one who cares about the configuration of the machine. But in my case the login into the domain is just for being able to access directories/servers in the domain (I do not really know the details, all I know is, that loggin into the domain user account is necessary). So overall I've got a local admin account and a domain account used on my machine. While working I'm logged in to my domain user account. But it annoys me, that I always need to enter the credentials of my local user account when I'm about to update/install something, which happens quite often as a software developer. I fixed this with adding the domain account into the user accounts in my control panel and putting it into the Administrators group. The only thing I wanted to know about this: is there something REALLY bad about doing this? Or is there maybe a more common way to be able to act like a local admin, while logged in as a domain user? PS: I'm sorry about the tags, but I don't know the proper ones. I'd be glad if some of the superuser experts could fix this :-)

• How to diagnose issue between mobo, RAID, and SSD cache drive? [migrated]

  - by goober

  Background This issue is happening on my custom-built desktop. Relevant specs: Motherboard: ASUS P8Z68-V PRO Utilizing Intel RST technology (application that uses unused SSD as cache) Processor: Intel core i7-2600k (not overclocked) HDDs: RAID1 of 2x Seagate Barracuda 1TB (ST31000524AS) (RAID performed via z68 chipset) Machine has run fine for ~1 year with no issues, and has been well-maintained (dust, etc.) What Happened Random Freezing issues -- intermittent Looked at the RST application screen to see that the acceleration cache was listed as "unavailable" -- recommended that I power down and reconnect the drive. Reconnected the drive to no avail. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Now, the freeze happens whenever loading something particularly data-driven (a video, a game, etc.) Steps Attempted Reconnected the drive to no avail. Updated Intel RST software to v. 11.6.0.1030 to see if that made a difference. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Connected the drive as its own volume. Formatted it, ran disk check errors -- all seems fine. Reconnected the drive and selected it again as the cache drive. Now, what happens when there is a freeze: Machine freezes I am unable to perform any command Screen then goes black I hit the reset button During boot, all drives show as "Disabled" and I am told no volume can be found I then hit the reset button (or power off/on) again. Either the next time (or sometimes after repeating this once more), the metadata cache is reconstructed and the system boots fine, showing the SSD as a cache. Question I believe this is an issue with the SSD itself, but how can I be sure since connecting it separately appeared to show no problems? I want to make sure it's not an issue with the motherboard, SATA ports, etc.

• Problem accessing the remote working space on my new SBS 2008 box

  - by Dabblernl

  This supposedly easy to install OS is starting to drive me nuts... SYMPTOMS: When trying to connect to the remote workplace I get (and ignore) the security warning because I am currently testing with the self issued certificate. After loggin in the remote workplace's main screen displays but the images on it do not load. When I try to click the email link I am thrown back to the login screen. If I try the login to exchange directly by typing in the remote.mydomain.com/owa address I get a 403 error that I am denied access. The problem occurs on both a vista and a win 7 machine. It seems that some security setting is playing tricks with me. How can I troubleshoot this?

• Apache and fastcgi - How to secure an Apache server with fastcgi enabled?

  - by skyeagle

  I am running a headless server on Ubuntu 10.x. I am running Apache 2.2. I am writing a fastcgi application for deployment on the server. I remember reading a while back (I could be wrong) that running CGI (and by implication fastcgi) on a server, can provide 'backdoors' for potential attackers - or at the very least, could compromise the server if certain security measurements are not taken. My questions are: what are the security 'gotcha's that I have to be aware of if I am enabling mod_fastcgi on my Apache server? I want to run the fastcgi as a specific user (with restricted access) how do I do this?
