• How to harden windows 2003 service account

  - by ITMan

  I remember there was a tech-net or WindowsITpro article about how to harden windows 2003 service accounts a couple of years ago. For backup software purposes (such as BackupExec / AppAsure / Etc.. , please don't bash these) I have to create a domain admin account (usually called something such as "backup") and have the services run from that account. In this article I remember you can create the domain admin user "Backup" however have it not able to login interactively. Do any of you remember such an article or have the knowledge on how to do it?

• Why doesn't openSUSE Linux upgrade itself through its software repositories?

  - by Dougal

  openSUSE - fast becoming my favourite Linux distro on the client - doesn't seem to upgrade itself through its own configured software repositories. Do we know why this is the case? Is it a money-making thing where they can then sell upgrade CDs / DVDs? I mean, pretty much every other Linux upgrades itself through the normal software repositories. For example, Ubuntu can upgrade itself from 10.4 to 10.10 just through the normal software package upgrade procedure. Why must it be a huge procedure to upgrade openSUSE? Any knowledge or ideas appreciated. Thank you.

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do.

• Connect macbook to my LAN through a VPN - best solution? [closed]

  - by LewisMc

  So I have a LAN connected via a ADSL/PPPoA, this is using a bog-standard DLink router supplied by my ISP (talktalk UK). I have a NAS within the LAN that is running FreeNAS and I want to be able to connect to it when I'm out and about. It's running an atom so it's quite low on juice consumption but I don't want to have it on all day and night so I've been waking it via a magic packet and booting it down from the web admin when I need it. So I want to connect to the LAN, I presume via a VPN, to be able to send a magic packet. But what is the best method to accomplish this, or is there an easier way? I've been looking at the cisco 857 integrated router and the Netgear prosafe 318(behind modem) but not sure If I'm on the right track with what I want to achieve as I've not much experience or knowledge with VPN's or networking (software engineering student). I have tried port forwarding but to no avail, either with magic packets or even connecting outside the LAN via DYNDNS. Thanks,

• Performance & Security Factors of Symbolic Links

  - by Stoosh

  I am thinking about rolling out a very stripped down version of release management for some PHP apps I have running. Essentially the plan is to store each release in /home/release/1.x etc (exported from a tag in SVN) and then do a symlink to /live_folder and change the document root in the apache config. I don't have a problem with setting all this up (I've actually got it working at the moment), however I'm a developer with just basic knowledge of the server admin side of things. Is there anything I need to be aware of from a security or performance perspective when using this method of release management? Thanks

• Raid 5 scsi fault

  - by HaLaBi

  I have no much knowledge about servers and I was looking all day around the internet about finding a solution to my raid 5 problem. All of a sudden two disks failed. The server won't boot (HP Proliant, windows 2003 R2, very old maybe 10 years old). I know that if one disk is faulty then I can add a new disk and rebuild it and things will be fine, the problem is two went faulty :( is this normal? two at the same time? is there any other thing I can do and I am not aware of? other than taking them out and reinserting them back? Windows won't boot. The Array menu shows that disks 0 and 4 are "Missing". Any other tricks or things to do? It is important because for some unknown reason the back up job did not work for a month and I just found out, so I need to make these raid 5 back online again.

• Suggestions for hosted file sharing services

  - by Jon

  Before I pose my question, I will give some insight as per my scenario: I work for a small business (cost is an important factor) Our bandwidth is limited and would not support an in-house FTP server We need to share files (mostly pdf, inDesign, Illustrator documents) to our clients, and as we expand, we are finding that our current locally-hosted FTP solution is too slow and is becoming a detriment to our sales team. What we need is a remotely hosted solution to share files with our clients, specifically with the following features: Greater than 100gb of secure storage The Ability to distribute unique log in credentials to clients, granting access to a personalized directory or folder, while limiting access to other files on the server. A relatively simple web-based UI for clients with limited computer knowledge We have considered a dedicated remote server, and web-based services (box.net, yousendit.com, onehub.com, filesanywhere.com) but I am unsure as per the direction we should be taking - have I left another solution out? What would you suggest? Thanks in advance.

• Any Windows based OpenID servers out there? [closed]

  - by Brian Knoblauch

  I've been looking to setup an OpenID server for a special project, but haven't found any workable OpenID server software packages. Originally was looking for a *nix solution, and found several, but they all had some kind of issue. So far I've tried JOIDS, community-id, and a couple others I unfortunately can't remember the names of. I've also come to the conclusion that even if I had managed to get one of those going that the management/upgrade cycles would have placed undue burden on the company (only a couple part time sysadmins with *nix knowledge, the day to day people are primarily Windows). So, I'm hoping that there's a Windows one out that will be functional that someone knows about and will be easy for a minimal support environment...

• Chrome opens to untitled blank page

  - by jackncoke

  I am working on a computer that had a lot of malware on it. I removed most of it to my knowledge. Now when I open Google Chrome I get a blank untitled page, with the traditional sign-in URL on top. If I go to the settings, the settings tab opens up blank as well. All pages that I navigate to will come up blank as well. The browser doesn't even perform a postback, it is like it is unresponsive. I did some googling and have seen people with similar errors, but no fixes. IE 8 works great without issues. Re-installing Chrome was the first thing I did! Any suggestions?

• First-class help desk solution? [closed]

  - by Andy Gregory

  A help desk, for larger companies is a place for centralized help within an enterprise to help the users of their products and services.Therefore,to find the solution that best fits your business requirements, it is important to research, examine, and compare help desk software. As far as I know,Hesk is an free helpdesk software with some limited features while h2desk can provide the hosted solution. But for my small business,i just need a web based help desk software which can provide ticket management and knowledge base faq. We need unlimited staff support. Maybe a freeware help desk software can not meet our needs. So,we are willing to pay for effective helpdesk solution. But it should be low cost. We have gotten two choice: iKode Helpdesk Nethelpdesk Our helpdesk team are tend to iKode Helpdesk. Any other efficient first-class help desk solution to share?

• Hack/software to easily move screen mapping of a wacom tablet?

  - by Riyaah

  I would like to move/manipulate the mapping of my Wacom tablet to my screen as easily as with Inklet: http://tenonedesign.com/inklet.php Is anyone aware of any software or hack to acheive this on Mac OS X? If not I'm thinking about trying to write a script that centers the mapping on the current cursor position, and then bidning that to a button on my tablet. Combined with a script for toggling between fullscreen/part of screen-mapping that should be enough. My idea so far is to edit the .prefs file since it's plain XML, and then restart the tablet driver. But any pointers relating to this would be most welcome, since my knowledge of this kind of things is rudimentary.

• tricks for speeding up tar while tarring up a huge directory of little files?

  - by Trevor Harrison

  I'm trying to tar up a directory that has about 3M tiny files in it. Tar is chugging along, but I'm thinking its going to take longer than I can wait. I'm wondering if telling tar to not store metadata (owner, group, perms) would reduce the churn on reading and re-reading this huge directory and maybe speed things up, and if there is a tar switch that does this. My initial perusal of the man page only gets me something like --no-xattrs, which looks like a start, but I was hoping someone had some specific knowledge.

• Good Choice of Memory for Asus K52F-BBR5

  - by Christopher Painter

  I recently purchased an Asus K52F-BBR5 notebook. It's a basic laptop with an Intel P6100 CPU and Mobile Intel® HM55 Express Chipset. It came with 3GB of DDR3 SODIMM memory and I'd like to expand it to 8GB. I'm a little confused by DDR3 nomenclature and not up to date on my knowledge of chipsets. I'd like to make a good choice when selecting memory for it. Crucial's database suggests using either a PC3-8500 with CAS 7 or a PC3-10600 with a CAS of 9. Is the 8500 better because of it's CAS 7 or will my chipset run the memory async at a higher speed and get better performance? Which would be a better choice for my chipset and CPU? Price difference is negligble.

• Application deployment with Puppet

  - by michaeltwofish

  I'm new to Puppet and while I've been using *nix systems for many years, I've never worked as a sysadmin or in ops. I'm currently writing Puppet manifests for hosting a set of (PHP/MySQL/MongoDB, code in git) web applications. Clearly Puppet needs to have some knowledge of the actual applications because I'll set up a virtual host for each one, but I'm not sure whether Puppet should be managing things like code deployment and database creation. Is Puppet an appropriate tool for application deployment? If not, can you recommend a more appropriate tool?

• How do I scale EC2 and push out code / data to my instances?

  - by chris

  Unfortunately I only have a limited knowledge of server architecture, I come from a development background. I am looking to ensure my new app can scale properly using EC2. I currently have a T1.micro for development running Windows with SQL server 2008. The system allows students to come to our site to search for a mentor, update their profile with pictures and employment history etc. Roughly the same sort of work as a LinkedIn profile. I need this to be able to scale very quickly without wasted resources. I understand the following is important. Separation of data, application etc. I will achieve this I think by hosting images using S3, Database instance via RDS and upgrade the EC2 instance. My main question is: How do I push data / code out to multiple ec2 / RDS instances seamlessly?

• 'Unlimited' free trial of Windows Server 2008 by deleting and reinstalling VM? [closed]

  - by MrVimes

  I am using Virtual Machine software (VirtualBox) to learn Windows Server 2008 R2 Network Infrastructure (70-642). Trouble is - I'm learning at an extremely slow pace and so the trial periods of my virtual machines are close to running out. If I delete the VMs then install WS2008R2 from scratch on new VMs is that violating the acceptable use policy of Microsoft? I am aware that I can extend the trial, but it seems I can only do that by 10 days at a time. Also I think having to re-install from scratch is a good way to reinforce the knowledge.

• Isn't ethernet used for LAN?

  - by Alraxite

  I'm not really knowledgeable about networking stuff, hence the stupid question. I read that ethernet was used for LAN connections but I'm pretty sure what I'm currently using to connect to the internet is 'ethernet'. The only knowledge that I have about networking is that there are two types of internet connections: Dial-up and broadband. And broadband can be either DSL or cable. So where does ethernet come from? The only thing I can tell is that I have a DSL model and there is an ethernet port at the back of it, a cable from which runs to a port in the back of my CPU. So, can ethernet be used to connect to the internet? Is it a subtype of DSL? I'm really confused about this, so I would really appreciate if someone could explain this to me. Also, I will apologize if this isn't the right place to ask.

• Windows Home Server restore causes computer to be removed from the domain?

  - by unknown (google)

  I restored my Dell M4400 that is a company laptop, and now I get an error when I try to log on and am connected to our corporate network, which says that the domain controller could not be found or that the computer is not part of the domain. Everyone else can log on, so it seems my computer is no longer part of the domain, even though it thinks it is per the settings. One thing of note: my computer crashed on 1/14/10, but I restored from a backup that was made on 12/20/09. So I am not sure if that made a difference? Also, I tried running "gpupdate" to update my group policy, but that did not seem to help. Any ideas? Seems like a bit of a flaw in the backup system for computers that are part of a domain. I guess I wanted to hear from someone with more knowledge about how a computer is recognized as part of a domain to know if this should be expected when doing a restore or if I should file a trouble ticket.

• How can an RSA key be placed in a "non-folder"?

  - by Phil

  I lack a lot of knowledge regarding the subject so please excuse me if my question is very ignorant. I just started out with RSA key authentication to my test-server. It did not work at the beginning and I tried and tried and re-tried to no avail. Then I realised, I was creating "mkdir ~/.ssh" and then "mkdir ~/.ssh/authorized_keys" before placing the id_rsa.pub into the latter folder, which did not work. My question is: How can id_rsa.pub be placed in "authorized_keys", which is not created by "mkdir" therefore not a folder? Thank you.

• Hyperlinks in Windows Update window not working?!

  - by w3d

  The actual links in the Windows Update window to open the relevant knowledge base article have stopped working. They still look like links, but they just don't do anything anymore?! This started happening (or not happening!) during the last Windows Update (around 2010-10-23). At the time I believe the first link worked OK and all subsequent links did not!? In the recent Windows Update (today) no links work. I can copy and paste the text of the link into the browser and OK. Web-like links from all other applications work OK. Dec 2010 - Windows Update links still do not work. I guess this must be something specific to my machine as I've not seen it reported anywhere else?!

Or if you have any knowledge, what is the best way to access your files remotely with maximum safety? but the same time the space that the files are allocated is protected against theft(encryption) etc. thank you

• Are Virtual-Desktop Managers good or bad for system resources?

  - by jasondavis

  I am looking at Virtual-Desktop Managers for Windows 7. Right now it seems that VirtualWin is supposed to be about the best one available for use on Windows. I have never used anything like this though and I am just curious from others experience and knowledge, does something like this hog up a lot of system resources? I do not NEED it but it is a nice feature to have when I do want to use it, my PC's performance is more important then using it. So is virtual esktop managers a resource hog or probably not? Please share any tips/advice/ or comments on them, thank you =)

• VPN between Cisco ASA 5505 AND Sonicwall SOHO3

  - by user41451

  Hello. I am trying to establish a site-to-site VPN tunnel between an old SOHO3 and an ASA 5505. The ASA has a static IP and the SOHO3 is dynamic. I have tried everything my limited knowledge lets me and need some advice on how to proceed! Phase 1 (according to the ASA logs) completes - followed by a message saying "All IPSec SA proposals found unacceptable!" so I guess the settings between the two don't match. I have played with various combinations and nothing seems to work - I am overlooking something, just not sure what it is! Any help would be appreciated.

• Accessing to shared folders with OpenVPN

  - by Ergec

  This is my first attempt to configure a vpn so I have very little knowledge about this. Network where centos server is having local IPs 192.168.123.* Network where windows machine is having local IPs 192.168.1.* I installed and configured my openpvn server on centos 5 and client on a windows machine. Generated all keys, certificates e.t.c and transferred them to client and I'm able to connect to server. Below there is a screenshot of the client log. Also on server side I can also see incoming packets with this command tcpdump -n port 1723 So I assume I did most of the things correct. But still when I try to open shared folders using \\192.168.123.33 or \\network-name I can't access folders

• Seeking easy to use Setup creator with logic and ability to write registry keys

  - by Mawg

  I want to create a Setup to install my application. It as to be able to do the following: ask a question (maybe 2 radio buttons?) and, depending on the reply, copy one of 2 DLLs to the Windows directory and invoke regsvr to register the DLL write some registry keys I would code my own program to do this, but I don't have enough knowledge of the different versions of Windows (XP, Vista, 7, etc) and 32/64 bit, registry layout, or permissions like UAC, etc So, it seems to me that it would be easier to use a Setup generator which has been around for a while and already handles all of this stuff. I went to my favorite site for free stuff and found this page. However, the programs mentioned there are either too simplistic or have too steep a learning curve for me. Can anyone recommend a Goldilocks solution which does what I mentioned in those two bullet points while taking into account all Windows versions, 32/64 bit, non-admin accounts, etc?
