• Asus RT-N66U forgets USB-Printer

  - by heysamhey

  about a week ago I bought the new Asus RT-N66U as the new Router in our little company. There are about 5 clients and 2 printers. There's a USB-only printer as well, therefor we bougth a router with USB-printer sharing. The setup and everything works smooth, but then after one day, and I still haven't found out why, suddenly the printer dosen't show up in the list of connected devices in the routers webinterface anymore. Of course I loose the possibility of printig, even though the printer shows up as "online" in the system settings. Can anybody guess the reason for this problem? Thank you very much

• I can't write to a folder which I'm a member of

  - by user3265472

  I'm trying to setup folder access to a group so that all members of that group can create/edit/delete files within the folder. # create my group and add a member sudo addgroup dev sudo adduser martyn dev Now, logged in as "martyn", check my user has been added to "dev" group groups martyn martyn : martyn dev Now I want to change the group ownership of my project folder so all members of that group can edit it and files/folders within it. sudo chgrp -R dev myproject Just to check: martyn@localhost:/var/www$ ls -l total 4 drwxrwxr-x 3 dev dev 4096 May 31 15:53 myproject Now here's where it fails. I want to create a file within myproject (logged in as "martyn", a member of "dev"): vi myproject/test ..but when I try to save the file I get the following error: "myproject/test" E212: Can't open file for writing Why, as user "martyn" which is a member of "dev", can I not write this file? Even if I create the file so it exists, change the ownership to "dev" then try to edit and save - I get the same error.

• Strange Windows Server 2008 R2 (FTP Server) Error - Caused by a specific combination of characters in the filename of uploaded file

  - by Steven

  We are running Windows Server 2008 R2, which is setup to be a FTP server. Everything seemed to be working fine until one our our cilents started complaining about their uploads being halted with the message "Connection with server reset". Further diagnosis revealed that a specific combination of characters in the filename will cause a repeatable error. I am hoping that a form expert can confirm the error or perhaps provide a solution. This is an example filename that will always cause the error: REPORT_FILED_000000001 (extension does not matter) Any help would be greatly appreciated! We need files named like this to work properly with our FTP server.

• Help Decide between C#/XNA client or Java

  - by Sparkky

  The game runs on a client/server architecture currently setup for TCP, and the client code was built in AS3 to be web based. What we're running into is 3 problems for the client. AS3 has no hardware acceleration so we are having some issues with slowdown when implementing some features TCP is really frustrating for a sidescroller when you're talking with a server. I'm having a heck of a time with the interpolation/extrapolation to make everyone else look smooth while minimizing lag. I would much rather be able to use UDP and throw in something similar to the age old Quake interpolation/extrapolation. No right click I work professionally with C#, and I did all my University (almost 2 years ago) with Java. Java really appeals to me because of the compatability while C# appeals to me because I've heard so much good about XNA and I love visual studio. For a Client/Server based MMOish sidescroller in your opinion should I stick with AS3 and the TCP protocol, or should I abandon some of my audience, ramp up the graphics and hit C#, or journey back to the land of Java. Thanks :D

• VPN Configuration

  - by Josh

  How can I allow incoming connections on a Windows 7 machine that is connected to VPN? I have some services listening on certain ports that I have forwarded from my router. When the VPN is disconnected, I can connect to these services from my internal network as well as from the Internet without issue. When I connect my VPN however, I am still able to access the ports from my internal network, but not remotely. I think I need a split tunnel setup, and there is an option in the VPN settings to Use Default Gateway on remote network. I want this option enabled so all my traffic is routed through the VPN, but I want incoming connections to be allowed on my internal network IP from the Internet. Is there some hybrid way to set this up with routing?

• Oracle E-Business Products New Search Helpers for Guided Resolution of Customer Issues

  - by user793044

  Oracle E-Business Proactive Support has created many new guided resolution documents that you may find helpful in resolving issues in your EBS applications.  These new documents are called “Search Helpers” and they guide you through your issue to a solution.  They are meant to be an easy and fast method to finding a relevant, complete solution. Hundreds of notes and service requests were reviewed and the best solutions to these known issues were selected.  For some issues, notes were updated to better clarify the solution.  In other cases, if a note with a solution did not already exist, one was created. You start the process by selecting the scenario you have encountered.  You may have received an error message, or there may be a particular area of the application in which you have encountered an issue.  Based on your selection of the issue, the Search Helper will present one or more additional possible symptoms.  When you have selected from both of these two sections, you are then presented with one or more articles known to have fully solved this issue in the past.  Several EBS products have produced Search Helpers documents.  Take a look at Doc ID 1501724.1 for an index of the current EBS Search Helpers.  Here is an example of a Search Helper from the Receivables Transactions area: After selecting the Functional Area of "Entering / Updating Transactions" a list of Known Symptoms is presented: And, when "Transaction numbers are not in sequence" is selected, a solution link is provided for Document ID 197212.1: How To Setup Gapless Document Sequencing in Receivables. The EBS applications that currently have published Search Helpers are: Advanced Pricing Applications Technology Configurator General Ledger Human Capital Management Inventory Management Order Management Payables Process Manufacturing Purchasing Receivables Shipping Value Chain Planning

• What can I do to configure my SSH such that it pauses for a flaky connection?

  - by kfmfe04

  I run ssh from OSX to a Ubuntu box - under home WIFI, everything works perfectly. However, when I ssh from certain external networks, ssh may be working fine for a minute or two and then drop due to a flaky network (diagnosed by pinging 8.8.8.8). How can I set up ssh so that it simply waits/pauses rather than drop (when dropping, I have to setup my development environment from scratch - a big hassle). EDIT When I say a bad connection, I mean, for example, ping 8.8.8.8 will work fine for a while, and then fail for 40-50 pings, and then come back on again.

• Danger in running a proxy server? [closed]

  - by NessDan

  I currently have a home server that I'm using to learn more and more about servers. There's also the advantage of being able to run things like a Minecraft server (Yeah!). I recently installed and setup a proxy service known as Squid. The main reason was so that no matter where I was, I would be able to access sites without dealing with any network content filter (like at schools). I wanted to make this public but I had second thoughts on it. I thought last night that if people were using my proxy, couldn't they access illegal materials with it? What if someone used my proxy to download copyright material? Or launched an attack on another site via my proxy? What if someone actually looked up child pornography through the proxy? My question is, am I liable for what people use my proxy for? If someone does an illegal act and it leads to my proxy server, could I be held accountable for the actions done?

• Automate Windows 8.1 Enterprise upgrade [migrated]

  - by Ben M.

  I have been trying to find the necessary command line switches for automating the upgrade for my Windows 8 clients to Windows 8.1. I have the ISO extracted and I've run setup.exe /? but that doesn't tell me enough. I can't find any relevant information from search engines. Can anyone point me to some documentation or information on how to automate the upgrade so that it keeps user data, programs, etc? I know how to do it when running the installer manually, but I obviously do not wish to do that with 100+ machines.

• Virtualization Solution for Family Use

  - by Dave Potts

  I'm trying to put together a solution for my family (wife + three kids). At the moment I have one newish desktop and a couple of aging laptops. There are always arguments over who should have the fast desktop. I'm thinking I would like to invest in a new powerful server and then run virtual desktops for each user off the server so that each user would have the same experience regardless of which actual PC they were using. I would like to use just a Linux based desktop, but unfortunately I need to support some Windows games for the kids. I've not tried wine for the games but would be willing to give it a try. Any advice on what the setup should be would be most appreciated.

• 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?

• TechEd 2012: Fast SQL Server

  - by Tim Murphy

  While I spend a certain amount of my time creating databases (coding around SQL Server and setup a server when I have to) it isn’t my bread and butter.  Since I have run into a number of time that SQL Server needed to be tuned I figured I would step out of my comfort zone and see what I can learn. Brent Ozar packed a mountain of information into his session on making SQL Server faster.  I’m not sure how he found time to hit all of his points since he was allowing the audience abuse him on Twitter instead of asking questions, but he managed it.  I also questioned his sanity since he appeared to be using a fruit laptop. He had my attention though when he stated that he had given up on telling people to not use “select *”. He posited that it could be fixed with hardware by caching the data in memory.  He continued by cautioning that having too many indexes could defeat this approach.  His logic was sound if not always practical, but it was a good place to start when determining the trade-offs you need to balance.  He was moving pretty fast, but I believe he was prescribing this solution predominately for OLTP database prior to moving on to data warehouse solutions. Much of the advice he gave for data warehouses is contained in the Microsoft Fast Track guidance so I won’t rehash it here.  To summarize the solution seems to be the proper balance memory, disk access speed and the speed of the pipes that get the data from storage to the CPU.  It appears to be sound guidance and the session gave enough information that going forward we should be able to find the details needed easily.  Just what the doctor ordered. del.icio.us Tags: SQL Server,TechEd,TechEd 2012,Database,Performance Tuning

• Windows Server R2 Task Scheduler - Open Programs On Startup

  - by Markive

  I want Fiddler and some other programs to run on startup, so it's there and running every time I bring up an instance of my test server on EC2. There's a few questions about running scripts on Startup with Task Scheduler, but this needs to work slightly differently. I have set this up to run on startup but when I RDP into the server I can see Fiddler is running in Task Manager (so I can't manually run a second instance of the program), but it's not viewable on the task bar? So I can't actually see the interface? Here's my setup: General Tab Running with highest privileges Run whether user is logged on or not Configure for Windows 2008 server R2 Triggers Tab At startup Others are obvious and defaults.. What am I doing wrong?

• Nodejs removing event listeners [migrated]

  - by JeffH

  Looking to get some help. I'm new to Nodejs and wondering if it is possible, to remove this custom event emitter. Most of this code comes from the Hand on nodejs by Pedro Teixeira. My function at the bottom is attempting to remove the custom event emitter you setup in the book. var util = require('util'); var EventEmitter = require('events').EventEmitter; // Pseudo-class named ticker that will self emit every 1 second. var Ticker = function() { var self = this; setInterval(function() { self.emit('tick'); }, 1000); }; // Bind the new EventEmitter to the sudo class. util.inherits(Ticker, EventEmitter); // call and instance of the ticker class to get the first // event started. Then let the event emitter run the infinante loop. var ticker = new Ticker(); ticker.on('tick', function() { console.log('Tick'); }); (function tock() { setInterval(function() { console.log('Tock'); EventEmitter.removeListener('Ticker',function() { console.log("Clocks Dead!"); }); }, 5000); })();

• HTTPS version of page throws 404, regular HTTP appears fine?

  - by Ryan

  I'm having a strange issue with a website in IIS on Windows Server 2003. It has a valid wild card certificate on it, however when I use HTTPS on the page I get a 404 not found. Without HTTPS it shows up fine. Also, if I go to the domain root of the site using HTTP the homepage shows up, but with HTTPS it REDIRECTS ME to a totally different website installed on the same IIS server. I am quite confused. I tried giving each site a unique IP address but it didn't change anything, I also tried changing the SSL ports, no luck. This IIS is setup to run PHP also. What could I check to resolve this?

• Protecting a webpage with an authentication form

  - by Luke

  I have created an employee webpage with a lot of company info, links, etc., but I want to protect the page because it contains some confidential company information. I am running IIS7.5 on Windows Server 2008 R2, and I already have the site setup as a normal, non-protected site. I want all active directory users to have access to the site. This is not an intranet site, it is exposed to the internet. I tried setting it up using Windows Authentication, but I had problems with multiple login prompts, etc. I just want a simple form for users to enter their credentials and have access to the site, and I need it to query the AD for login. I've searched the web for a guide on this, but I can't seem to find one that fits my situation. This is not a Web App. It is just a simple html site. Does anyone have any suggestions or a link to a guide on this? Thanks so much! -LB

• Reverse proxy with SSL and IP passthrough?

  - by Paul

  Turns out that the IP of a much-needed new website is blocked from inside our organization's network for reasons that will take weeks to fix. In the meantime, could we set up a reverse proxy on an Internet-based server which will forward SSL traffic and perhaps client IPs to the external site? Load will be light. No need to terminate SSL on the proxy. We may be able to poison DNS so original URL can work. How do I learn if I need URL rewriting? Squid/apache/nginx/something else? Setup would be fastest on Win 2000, but other OSes are OK if that would help. Simple and quick are good since it's a temporary solution. Thanks for your thoughts!

• SharePoint 2010 MySites - Simple explanation needed!

  - by Chris W

  I've been playing around with the 2010 beta for a couple of weeks, experimenting with topology options etc. I think I've got myself totally confused as to how it works hence if there's any SP experts out there that can explain things in simple terms for me I'd appreciate it! I want to setup a farm with 3 servers providing the content & MySites. I presume that the way to do this is to load balance or DNS round robin traffic between the 3 servers. The bit where I'm confused is that My Site Settings page asks for a specific My Site Host hence all my site traffic will be pushed to a single server even though we have 3 in the farm. If this hosts fails I presume MySites will be unavailable. Is this right? How do I configure it so that access to MySites is load balanced across the 3 servers in the farm?

• Is it reasonable to make a RAID-1 array with a ram disk and a physical disk to maximize read performance and protect data?

  - by Petr Pudlák

  In one of the answers on SO (I forgot which one) I've seen a suggestion to make a RAID-1 array composed of a RAM disk and a physical partition. By adding the physical partition with --write-mostly and enabling --write-behind the system should read everything instantly from the RAM disk but still save all data to the physical partition so that the data are preserved and the RAID array can be assembled again after reboot. Is such a setup reasonable? Will it perform any better in some scenario than having just the physical partition and perhaps tweaking the kernel to favor disk cache (swappiness and vfs_cache_pressure)?

• MS-Outlook add-on to move a new message to the same folder as the rest of the thread

  - by Guss

  I'm forced to use MS-Outlook in my job, while I very much like the feature that shows all the messages of a discussion thread (that are stored in different folders) in the inbox when a new message is received for that thread, if the previous messages are in a different data file (which I'm forced to have as the MS-Exchange server quota is very very small) then the message list only shows the name of the data file and not the name of the folder where the messages are stored. As a result, because I file my message by context (i.e. all the emails for project A go into a "Project A" folder, etc), and its important for me to have all the messages in a single thread in the same folder, it is sometimes hard to figure out into which folder should I file the new message. It would be great help if there was some add-on or VBA script that I could add to my setup that will offer a shortcut key or a button to "file this message to the same folder as the previous messages in the conversation thread".

• Running a VM off of an external HD via USB

  - by Nelson LaQuet

  Is it viable to run (i.e. reference the vmx/vhd directly from the mounted drive) a VM (vmware running Windows Seven) off of an external HD via USB? I mean, I know it's possible, but I guess I'm asking if USB provides enough bandwidth for normal usage... If so, are there any particular brands that may be better or worse? I know that ESATA would be a more viable setup, but my laptop doesn't have an ESATA port. Currently I use the VM to segregate all of my work development servers and software from my main machine; so I will be running all development servers and tools on the VM directly.

• Install Ubuntu side by side with Windows

  - by Igal

  I'm trying to setup both Windows 7 and Ubuntu 14.04 Desktop on the same machine. I've partitioned the disk into 3 parts, so that I can have Windows Ubuntu Shared Partition for Files I've installed Windows 7 on the first partition (which created a small partition of 100MB for boot), so now I have 4 partitions on the disk which is all it can take. Now I am installing Ubuntu, and it's asking me whether I want to: Install Ubuntu inside Windows 7 Replace Windows 7 with Ubuntu (No!) Something else I want the Ubuntu installation to go into the partition that I prepared for it. Should I choose "Something else"? If I do so -- will I be able to choose which OS to load at boot? Can anyone explain how "Ubuntu inside Windows" work? it says that it will allow me to choose which OS to load at boot, which is desired. UPDATE: When choosing "Something else" I see also an option for Device for Boot Loader Installation: /dev/sda -- the ssd disk itself /dev/sda1 -- the Windows 7 loader (100MB partition) /dev/sda4 -- which is one of the other partitions Which one should I choose there? TIA!

• Web log files analyzer

  - by Peter Štibraný

  I already use Google Analytics on my page, but I'd like to get additional info from log files. I've looked at various packages during last days, but nothing impressed me so far. Some requirements: must work on log file level (I use apache combined logs, but can configure apache to produce other types of logs) can generate static reports (windows/linux) or use GUI (windows only) should be easy to add custom user agents, and rerun analysis if it can recognize installation of eclipse plugins from log, that would be big plus understands google serp position referer should not require two days to setup (awstats, I am looking at you) should be still under active developement (i.e. analog isn't good answer) preferrably free, or at not very expensive :-) Any good analyzers programs out there?
