• Bind include all zones in a folder

  - by alexcepoi

  I have a webapp that acts as a DNS manager, writing all zones to "/var/named". I would like to be able to configure named to load all zones in that folder, without explicitely having to tell it which zone goes to which file. Is that remotely possible? The reason for this is that i will be having a lot of zones added/deleted and a lot of records for each of them. I was thinking for using a database for that, but the idea of doing 500 record inserts scares me (it needs to be snappy). It's easier to write to a file. Any suggestions?

• Windows Home Server is showing signs of death

  - by Guy

  I have a Windows Home Server (HP EX485 MediaSmart Home Server) and it started acting up about 4 weeks ago and a few days ago complained of a corrupt database and would I like to try and recover it? Yes, I would but I ended up losing all backups. I have to reboot it frequently for the client machines to be able to see it. I have 4 hard disks in the computer. I suspect that the primary hard disk is going bad. My first question: How can I confirm if it's going bad or not? I'm thinking about removing the primary disk and replacing it with one of the others and reloading the OS with the server restore disk. I know that I'll lose everything (but I recently did anyway) but is there any other reason why I should not do this?

• Suggestions for someone wanting to become a Laptop Reseller

  - by Josh B.

  First of all, to give you a little background... I have had my Microsoft A+ for several years now. I used to run a small business repairing Xbox 360 consoles and I am currently a Network Engineer for a company in Ohio. I definitely know my way around a computer. I miss running a small business on the side and I'd like to get something going again. There is a really high demand in my area for Laptops and I was thinking about starting a small Laptop store out of my house. What is the best way to do this? I was assuming that the best way would be to buy barebones systems and build them yourself. If this is the best method, I would be very interested in any resources to get parts and such. Apparently Laptop parts aren't the easiest thing to come by (especially at a good price). Does anyone have any suggestions about how to get something like this going?

• how to create a simple radio station [on hold]

  - by John

  I've been digging around for ages but not getting very far so any links or tips would be massively appreciated. I want to create a central "radio station" in my home to stream one playlist to any computers pointing their browser to the ip within my internal network. I have an old mini slave mac mini running ubuntu and was originally thinking I could get php and apache to handle this but then quickly realised that of course, php will serve out streaming independently per connection ie no radio station. Are there any servers already built for this sort of behaviour? is shoutcast one of the only versions Thanks, John

• startup cassandra layout

  - by davidkomer

  We've got a relatively low-traffic site (~1K pageviews/day) hosted on a single server, and expect it to grow significantly over the next few years. I'm thinking of moving over to Rackspace CloudServer or EC2 and firing up 3 nodes (all on CentOS): 2 x Web (Apache) - with loadbalancer 1 x MySQL (for the Wordpress powered part) The question is where to put Cassandra right now... Should it sit on each Web node, or the MySQL node? My thought right now is to put it on Web nodes. It's my understanding that Cassandra has the benefits of fault-tolerance (i.e. if we take a node down, the site is still operational). So even with only 2 nodes, we'd have that benefit as opposed to just putting it on the MySQL node. Also, as we scale up and add another node, a cassandra instance can come along with it and the php can always run its queries on localhost. Is this a good idea?

• Virtual Windows Servers and Pagefile location [closed]

  - by Luke Puplett

  Considering that Windows makes heavy use of the pagefile even with huge amounts of RAM available, is it not best to have this pagefile on the fastest disk possible as close to the virtual systems as possible? I'm thinking, RAM disk. Where I work, storage for VMs is out on a NAS/SAN. I'm worried that so much memory access is having to go across the network! As a side, I think its about time MS got rid of paging and told us to buy more DIMMS. UPDATE So this question has been downvoted??! Accessing a local spindle is C40,000 times slower than a DIMM, so going over the network will be even slower for hard faults. I don't know why I got the downvote, I'm certain that this is an issue unless there's some other mechanism in ESX/HyperV that manages this.

• Is Zabbix the right tool for me?

  - by hortitude

  I just want to monitor a small handful of servers (less than 10). From reading various places it sounds like the top leading contenders (for open source at least) are: nagios munin zabbix From what I have read a lot of people tend to use munin and nagios together -- munin for history and graphs, and nagios for alerting. On the other hand it sounds like Zabbix is a more complete solution and easier to configure than either of the other two. So I was thinking of going that route. My thoughts right now are: What are the general disadvantages of Zabbix? Does Zabbix have a small footprint on boxes it is monitoring? Do I really need to setup an entire other server for it? I currently have a server that is under very light load -- can I dual purpose it?

• Digitizing notes?

  - by Nimmy Lebby

  I want to digitize my note taking. I was looking into using tablets or something of that sort but I feel that it would be too much of a challenge to type instead of actually writing my notes during meetings. That got me thinking into looking into something like LiveScribe. It looks neat but I don't know how it would work in the real world. How does OCR work with something like smart pens? How is the desktop applications? Any experience? Does anyone have an alternative suggestions? Positives and negatives? Any advice would be helpful.

• Storage of various linux config files

  - by stantona

  I'm using git to track/store all my various config files required for linux. They're organized as if they live in my home directory, eg: .Xresources .config/ Awesome rc.lua .xmodmap .zshrc vim/ <- submodule emacs/ <- submodule etc I use git submodules for other things like vim/emacs configuration (since I also want to keep those separate repos). I'm thinking of creating a shell script to create the various links to these files. The goal is to make it easier to setup another linux painlessly. Is this a reasonable idea? Is there a preferred approach? I'm mostly interested in hearing how others people store their configs.

• Why does my laptop shut down, does it get too hot?

  - by Kevin P.

  When I play games, or use powerful-applications such as Autodesk Maya, my laptop just shuts down, ofcourse without any warning at all. This is what I've tried so far: Cleaned my fan, completely! Checked if I have enough RAM and good enough graphics card, and I do. (6 GB RAM, Nvidia GeForce GT540M with 2 GB VRAM) None of these options worked. Even tried to clean my fan twice! Now, I have some options I could also try, but I don't know if that have anything to do with it or not. I was thinking reinstalling my Windows 7, because maybe it has to do something wrong with the installation? My laptop is about a year old, and this problem just happend out of no where, short after I downgraded from Windows 8 Release Preview to my original Windows 7.

• What is a good web interface for remote linux load monitoring?

  - by Jakobud

  I'm looking for some type of remote linux monitoring software that you can view using a web interface. And I'm not just looking for the basic load information. I'm also looking for process information, similar to the info that you get from TOP. Like I'd just like to be able to pop open this webpage to view whats going on with the server at a moments notice. For example, perhaps just a basic PHP page that is on the server that uses basic AJAX to display and refresh results from the TOP command in the page. I was thinking about writing something like this, but I don't want to reinvent the wheel.

• Need to move a debian server from i686 to x86_64 architecture

  - by user64204

  I have a debian server that I need to move from one hosting provider to another. I don't really know how the old server was setup, all I know is that it's running a Ruby on Rails application with a lot of custom libraries installed and that I should prepare myself for a painful migration. Old server: -os: debian 5.0.9 -used disk space: 3.2GB -architecture: i686 New server: -os: debian 5.0.9 -free disk space: 10GB -architecture: x86_64 As you can see the problem is that the servers are running different architectures. Q: Is there anyway I could somehow migrate the old to the new server in a few steps (or am I just dreaming I could) ? I was thinking maybe I could: -get list of packages and gems installed on old server and use for loop to install them all on the new -copy the disk content from old to new server while excluding what is architecture-specific (the problem is that I don't really know what to exclude).

• Windows Vista Backups?

  - by skaz

  I am trying to configure a Windows Backup on Vista but don't see some capabilities I would expect to be there. For one, it looks like I can only select a Local Drive or a network share. I want to use a local drive, but I want to use a sub folder of one of the drives. Must I really pick the root? As a work-around, I made a network share to the local drive, thinking I could then pick network share. However, when I do this, I am prompted for credentials to hit the share, and none work. However, the share works Explorer, and it works from other computers, so the access is configured correctly. Is there any way to do what I am trying to do? Thanks.

• Examples of applications where messages are guaranteed to turn up imediately

  - by James Hay

  I'm trying to find an example to show where data is sent from somewhere, whether manually or automatically, and is received IMMEDIATELY by the recipient, (doesn't matter whether we're talking mobile, desktop or whatever). An even better example would be where there were multiple recipients for the same message. It doesn't matter what the data is or the context it's used in, only the immediacy of receiving it. I was thinking that there might be some example in finance and the stock markets, but I haven't been able to find any through googling. IM clients are a great example of this and I think I'm basically looking for examples of applications that communicate over sockets. If anyone works on applications of this nature or knows of particular implementations, can you give me a quick run down of the use case and if it's commercial software the name of the software. This is all basically for research purposes so doesn't have to be particularly detailed. If anyone can help, thanks.

• Does using VLANs in your network infrastructure cause an appreciable decrease in performance?

  - by Peter Grace

  This is something I've never considered before and wanted the opinions of the experts. We use VLANs day in and day out for various network tasks. My modus operandi is that in general, if something supports VLANs, that port is getting trunked because it just makes a ton of sense if there's even the slightest chance you need to do more than one thing on that single link. As I ponder this, though, I'm wondering whether there's a performance penalty involved with this line of thinking? Is the impact negligible?

• Mostly offsite asset management (laptops/smartphones) - what is a good SaaS based solution?

  - by Jack T

  Most of our company assets are offsite. Everyone either works at home or onsite at a customer. Most asset management/audit/remote control software concentrate on company LAN based assets. We don't need an NMS as we use OpenNMS in the internal network. I was thinking of something like Altiris Client Management Suite but since everything is connected to the internet a SaaS based solution sounds like the ways to go. LogMeIn Central looks ok but not that comprehensive. What do you guys use?

• NIS AD password synch for new accounts

  - by user135004

  I have a Win2k3R2 DC with NIS. All is working well but its no longer synching the passwords for new accounts. When creating a new AD user, NIS does its thing and sends its Unix account to the synched linux server. It's doing everything its supposed to do but not the users password to the server (getent passwd returns the ABCD!efgh12345$67890 password for the new account). Thinking that password synchronization is not working, I changed the password of an existing working account and it synchs the new password. If I delete a new or old AD user, it deletes it on the linked linux server as well. All this tells me that NIS is doing its thing (at least with existing accounts) No updates have been installed on the DC. I am not even sure where to start here.

• Sync two external harddrives?

  - by acidzombie24

  A little mishap happened earlier today and i am thinking i should have a copy of my external harddrive since 10% of it is very valuable. What is the best solution to keep two external harddrive in sync? i'll probably use one as regular and maybe use the other only to copy data. The easiest way to keep it in sync is to clear one drive and copy the other but 1T of data will take a long time. Whats a good existing app that will keep them in sync? freeware preferred.

• Upgrading MacBookPro

  - by moray95

  I'm using a Late 2011 13" MacBook Pro with an Intel i5 @ 2.4 GHz and 4 GB 1333 MHz ram. The computer has started to get older. I was going to upgrade the ram but since Mavericks come out, the ram problem just went away and now, it started to get slower and slower. So I was thinking of upgrading my ram to at least 8GB and my CPU. I have two question about that. As I have 1333Mhz rams installed by default, the motherboard should not support 1666Mhz rams. But can I use 1666 Mhz ones and if I can will it make any difference? Also is it possible to upgrade the CPU of my computer? If yes how can I find a CPU compatible with the other components?

• IIS - Script for repeated hacks on a website

  - by dodegaard

  I currently have a site that is armored by ELMAH as its reporting mechanism. Each time someone hits a URL that is incorrect it notifies me or logs to the system. This is annoying for someone fat-fingering the URL with a misspelling but great when a hacker is trying to crack a site of mine. Has anyone ever written a script for IIS 7 on Win 2K8 that blocks an IP based on repeated attempts to hit a website? I've looked at Snort and other IDS systems but if I could get a script that could be linked to my ELMAH system it might be the perfect thing. PowerScript, etc. is what I was thinking. Hints and recommendations are wonderful and if you think a true intrusion detection system is recommended give me your ideas. Thanks in advance.

• Multiple connections to the same Wireless Network in Windows 7

  - by Jamek

  Hello, my university just limited bandwidth to 512 kbps (that's 64 kB/s!) for each connection. I was thinking to make multiple connection to the same wireless network (called "internet"), is this possible under Windows 7? I know it's possible to connect to more than one WLAN through the "hostednetwork" concept in netsh: netsh wlan set hostednetwork mode=allow ssid=xxxxx netsh wlan start hostednetwork However this method doesn't seem to work, I don't know if it's due to the authentication method (through certificates while hostednetwork seems to support just a "passphrase") or because I'm already connected to that network with the same MAC. Can you think to some tool able to do this?

• Best blog package/platform (java, php etc)?

  - by user50912

  Hi Folks, I want to set up a blog, but I want it to reside on a URL I've bought, I also don't want any of the ads and such that sit around other blogs on blog specific sites like blogspot and generally want more control. I was thinking of getting shared hosting with mysql and such to get it going (as opposed to a VM which would be overkill). Then I just need to decide on the easiest quickest (and most secure) way of getting something up there. After some googling, I see b2evolution.net which sits on php, or Apache Roller, which seems to sit on Java. Could anyone offer any advice on whats my best approach here? Are there security concerns with either or has anyone any experience in this area? I really want setup time to be minimal, so I can concentrate of the feel of the blog rather than whats under the hood. Many Thanks.

• Browser which shows what's been downloaded so far regardless of formatting and layout ?

  - by Mick

  Every now and then a website becomes super-slow (but not broken) because there are too many people looking at it at the same time. When I try and view such a site, say with Firefox, I can see that it is downloading all sorts of components of the site because of the progress information printed at the bottom of the window and I'm sitting there thinking "If only the browser would show me what it's got so far. I don't care if its a jumbled mess, I just want to see what you've got". Does any browser offer such an option?

• VPN/Proxy server to bypass work proxy

  - by Trevor

  Here is my dilema, I am at work and can not set up a VPN connection to my VPN account in the USA. So what I would like to do is somehow have my "IE" at work connect to my home network and route any internet requests through my home PC to my VPN account, so I can access my USA Contents? So what I was thinking and I am not sure if this will work, but set up a proxy server at home on my home computer, that then routes all requests to my VPN Tunnel to the USA. Have my work computer use my home computer as the proxy and viola I have unrestricted internet access? Does that sound feasable? Thanks.

• What's the typical latency for key strokes using an ssh connection on a local wifi network?

  - by dan

  I develop software on a Macbook Air 1.6 Ghz but find running Rails test suites and generators on this computer very slow. I'm thinking about buying a Linux tower to put on my local wireless network to do my Rails development on. I would want to use my Macbook Air and ssh into the Linux box and do my development with Gnu Screen, vim, etc. Can I expect the keystroke and echo latency for a ssh session between two machines on a local wireless network to be negligible? Does anyone develop using this kind of local setup?
