• Can I use only a HDMI monitor?

  - by Felix

  I recently found out there are such things as PC monitors with TV capabilities (or TVs that can be PC monitors), and the idea kind of tickles my fancy. I'm thinking of getting one of these gadgets, and if I do, I will connect it to my PC via HDMI (my graphics card has builtin HDMI), so that I also get sound to the TV. The reason for this is because I have a 2.1 sound system which I want to use both on the PC and the TV. Basically, I want the configuration to look like this: Cable --------> TV --> 2.1 Sound System PC --HDMI--> TV --> 2.1 Sound System My question is: can I use a setup like this? Can I not have a classic VGA monitor? Will I be able to see non-graphical interfaces (such as the BIOS, GRUB, a Linux terminal, ...) through HDMI on the TV? I use Windows 7 and Ubuntu.

• 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.

• Automating the insertion of credits in video files on Mac OS X

  - by Roberto Aloi

  I have a bunch of video files (mp4). I need to insert some title information at the beginning and some credits at the end. I'm currently using iMovie. Since the title could be extracted from the filename and the credits are always the same, I'm wondering how could I make all this process as automatic as possible. I was thinking about Automator, but I'm open to any other solution. iMovie is the preferred tool so far, but I could use anything else (as far as it doesn't require additional licensing/cost). Any idea?

• 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?

• ext4: error loading journal

  - by cloudyOutside

  I have an external hard drive with two partitions: A small FAT32 which is mostly empty and works fine and a large ext4 with tons of data, most of which isn't backed up. The ext4 is visible, but can't be mounted. I get an "error loading journal" error. The drive is a Western Digital Caviar Blue 500GB. Roughly 30GB of that is FAT32 and the rest is the ext4. The light on the enclosure turns red when reading from the bad partition. It was made by Cavalry. There wasn't any warning, but coincidentally, I've been thinking lately that I should get two large capacity drives for real backups. Is there anything that can be done? I'm not even sure I have enough storage to backup everything even if it is redeemable.

• Remote Software Solution that Acts as a Client

  - by Richard

  I am looking for something that I am not sure exists. I have a remote computer that will not allow incoming traffic due to ISP blocking of ports(basically double NAT situation that I am unable to get around). I am wondering if I have a computer acting as a client, is there any solution out there that will allow remote access to the computer. I do have other servers on the net that have static IP's that the computer could initiate a connection with. I am thinking of using Debian Linux, However computer is not built yet so OS is not overly important at this point.

• mosh-like port forwarding

  - by Marc Merlin

  This is on linux, connecting to linux servers: I love mosh, but it doesn't support port forwarding, and likely won't for a while since it's been almost a year now and it hasn't happened yet. port forwarding over ssh is great, but because my laptop moves between networks several times a day, my ssh sessions die, and so do the port forwards. I could script/hack something to detect hung ssh and reconnect to get my port forwards back, but before I do this, is there another way to do long lasting port forwards when your source IP changes several times daily (because you go on different networks)? I'm thinking an ssh over UDP would do the trick but of course ssh is over TCP.

• What type of wireless adapter for Verizon Fios?

  - by ShoeLace1291

  I have verizon fios internet service. I believe they use a Wireless G router, but I just have one question. I currently am using a 54mbps wireless pci adapter in my Windows 7 custom build. It drops the internet connection all the time and is starting to get very irritating. I'm thinking about buying a new one, but all the 300mbps cards on newegg are wireless n. So my question is, will a wireless n network adapter make a difference with a wireless g router?

• 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).

• mac osx software always order files alphabetically rather than by type.

  - by george

  i have noticed many mac applications sort the files alphabetically rather than by type. a good example would be coda by panic.com the files in the file menu are organized alphabetically, i requested for them to add the feature to organize files by type and they've said that its a finder thing. so i went in search to look at other applications to see if they were organizing by type i noticed dreamweaver cs4 had this same problem and now including dreamweaver cs5. there has to be something in the mac that does this and that i can modify. i played with spotlight and it now displays its files by type (thinking thats what i can do) but it didnt take affect in other applications. what library are these applications using to display a file menu for its files?

• How to efficiently dump a huge MySQL innodb database?

  - by Jagbir

  I got an Ubuntu 10.04 production MySQL database server where total size of database is 260 GB while size of root partition is itself 300 GB where DB is stored, essentially means around 96% of / is full and there's no space left for storing dump/backup etc. No other disk is attached to server as of now. My task is to migrate this database to other server sitting in different datacenter. Question is how to do that efficiently with minimum downtime? I'm thinking in line of: Request to attach an extra drive to server and take a dump in that drive. Transfer dump to new server, restore it and make new server slave of existing one to keep data in sync When migration is needed, break replication, update slave config to accept read/write requests and make old server read-only so it won't entertain any write requests and tell app developers to update there config with new IP address for db. What's your suggestions to improve this or any alternate better approach for this task?

• Optimal Instance Size for EC2 Sharepoint Server

  - by Rob Wilkerson

  I'm surprised that I can't find any info about this, but I'm not a Windows admin and just a novice EC2 user. I have a client who wants to stand up a Sharepoint server on EC2 for internal use. The team is small (10-20) folks and traffic will be light. Mostly, the client is looking for one place to store documents (and revisions of documents) while making access easy for authenticated users anywhere in the world. They've settled on Sharepoint and have other EC2 instances so that seems like the natural fit, but I'm trying to figure out what to recommend for them. I'm currently thinking about a Medium instance. I'm afraid to go smaller because I think Windows would need a fair amount of memory just to run, but I'm very open to suggestions. Any advice would be much appreciated. I expect that the storage itself would happen in an EBS mount, but again, suggestions welcome. Thanks for your input.

• How do I create email addresses for all my users using my domain ([email protected])?

  - by user33012

  My client wants to create email addresses for all their dotnetnuke users using their domain. The point is to keep the user's email addresses 'private' while still allowing communication through a public email address that they can control. It's not necessary to have a full webmail interface (although that would be nice). I'm thinking it would be enough just to forward any mail on and just act as a gateway. So if an email was sent to [email protected], it would be forwarded on to the email address associated with the dotnetnuke account with username 'rwain'. Is this possible to do in a shared hosting environment? Or do I need to create some custom mail server that does a conversion of the email address and forwards it?

• configuring linux server to send traffic to local machines using local IP address

  - by gkdsp

  Two linux servers, server1 and server2, are on the same local network (they also have access to an external network). Server2 has a local IP of 192.168.0.2 and a host name of host2.mydomain.com. QUESTION 1: If an application on server1 sends traffic to server2 using a host name of host2.mydomain.com, what determines whether this traffic is routed to server2 using the local or external network? QUESTION 2: To ensure that all traffic sent from server1 to server2 always uses the local network, could I simply include in the server1 /etc/hosts file the following? 192.168.0.2 host2.mydomain.com ...the thinking being, if the servers are always on the same network there should never be a need for server2 to send traffic to server1 via the external network (that I can think of anyway). Is this done in practice, or is some other method preferred?

• Connect two devices with ethernet

  - by mofle

  I have a MacBook Pro and I'm going to buy a Boxee Box. I have access to wireless internet, but it's slow and out of my control. So my question is, what is the best way for both devices to get internet access, and the Boxee Box to get SMB access to the Mac, when only the Mac is connected to the wireless internet? I'm thinking an ethernet cable from the Boxee Box to my Mac, and connection sharing on my Mac. Can you explain the setup, is there any configuring.

• Error 404 when accesing newly created ASP.NET website on IIS 7.0

  - by Wodzu

  I've created an ASP.NET website and published it to a file from visual studio. Then I've copied my folder to the inetpub\wwwrot directory. Next under IIS I've converted this folder to the application. Unfortunately, when I try to acces it like this: http://localhost/myappname I am getting 404 error. I was thinking that maybe IIS is not configured to process aspx files, but under http://localhost/default.aspx there is a working sharepoint website. Have you got any ides where might be the problem?

• 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?

• How much power supply do I need for my server, and could a shortage be causing my odd crashing?

  - by dolan

  I have 5 servers, all with similar hardware (i7, four 2tb 7200rpm drives, two 4tb 5400rpm drives, 430 watt power supply), and lately the machines have been freezing up. This has gotten worse in the last day or so, and I can't pinpoint any explanation. One recent change was adding the two 4tb hard drives. The crashes happen most often while running a large Hadoop job, so I was originally thinking the load was causing some issues, but last night one server just froze without any heavy load on the box (or so I think), other than HDFS (Hadoop's distributed file system) was probably rebalancing itself since two of the five nodes were offline. If I plugin a monitor and keyboard to one of these frozen machines, I can't get any response or feedback on the screen. Any ideas on possible points of failure and/or different logs I can look at to investigate? Thanks Edit: The systems are running Ubuntu 10.04 Edit 2: More on hardware: intel core i7-930 bloomfield 2.8ghz processor (quad core) 12gb (6 x 2gb) kingston ddr3 1333 ram antec earthwatts green 430 power supply msi x58m lga 1366 motherboard

• How to load previous kernel via ssh?

  - by Aamir

  I work remotely on my work computer. I am also the root of the workstation that I am sharing with my colleague. Yesterday, I upgraded the kernel to 2.6.31-17 when asked by the update manager but refrained from restarting because I knew my NVIDIA and several other kernel modules wouldn't work. Unfortunately my colleague who is a linux noob restarted the machine and here I am :( I am thinking of changing the symlinks /initrd.img and /vmlinuz to the previous kernel image and use kexec. Please tell some better way to load the 2.6.31-16 release of kernel from ssh and not the grub boot menu. I am using Ubuntu Karmic.

• Windows 7: Use VirtualStore technology as user for own benefit?

  - by mfn

  I've researched a bit and came to the understanding that VirtualStore is part of the new UAC feature in Vista/W7 which is the file system part of the transparent data redirection and redirects write access to folders like program files to C:\User\<username>\AppData\Local\VirtualStore\ in lack of applications respecting the LUA principles. Now I'm interested if that kind of transparent redirection can also be used as a power to the user. Here's an example which comes to my mind: I install any kind of software to e.g. D:\Whatever\ThisAndThisApp\ and I set up things that, after initial installation, any write access to this folder is transparently redirected to e.g. D:\MyOwnVirtualStore\Whatever\ThisAndThisApp\file_only_writable_here.txt. Is this thinking too far or can I actually use that power of VirtualStore as a user on Windows 7? I'm using the Professional version of that matters.

• What constitutes valid justification for more IP addresses?

  - by David

  I host a small website with a well known VPS service. They provided me with one IPv4 address upon registering and said additional addresses would require justification. I requested one additional IPv4 address so as to have one for a production environment and one for a testing/QA environment. They said this was unnecessary as I could just use alternative TCP ports for the test environment. I can live with using a non-standard port for non-production hosting, but it got me thinking, what would be valid justification? (I asked them and they didn't want to answer). Is there an industry standard for what counts as "valid" justification for additional IPv4 addresses?

• How to generate new CSRs for TLS use in sendmail?

  - by Mikey B

  SendMail 8.13.8 | CentOS 5.x Hi Guys, I'm using ca-signed TLS certificates on my sendmail server and they are up for renewal soon. Our new CA doesn't like our old CSR so I need to generate a new CSR. Can someone point me to the procedure for doing this (without affecting the production certs that are already in use)? I'm paranoid of overwriting the old TLS certs in the process of generating a CSR. Most of the instructions I've found are for implementing self-signed TLS certs -- which isn't an option for me at this time. I'm thinking it would something like: openssl req -new -nodes -out new-tls.csr -keyout new-tls-private.key But I wasn't sure if I was missing some options there such as the -x509 option... -M

• Getting More Performance out of a MacBook Pro

  - by 5arx

  So I've got a mid-2009 MacBook Pro 13". Integrated GPU so not a games machine but fast enough for doing .Net development in VMs. I love the little thing and wanted to give it a Christmas present so thought I'd mod it up a bit and give it a boost. I'm thinking of swapping out the stock 5400rpm HD with a faster hybrid drive (has 4GB RAM and spins at 7200rpm) but was wondering if any of you had tried or knew of anything else I could change/upgrade/mod to squeeze more out of my laptop. Before you answer though, please be aware that I'm not sure I can run to putting in the 8GB of RAM Apple have suggested :-( Thanks in advance.

• 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.
