• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Web Browsers Software Tools Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers Drawings If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• SSH: Tunnel multiple ports to remote server

  - by user1594322

  See attached diagram. Host A - Windows server Host B - Linux server Host C - VMWare ESXi server From host A I can SSH to host B over the VPN tunnel. I can ping host C from host B, but not from host A. I am assuming this is because host C has lost its default gateway. Host C is a VMWware ESXi server, so I would need to tunnel several ports (80,443,902) in order to reach host C from host A. What is the correct ssh syntax to create the tunnel in order to reach host C from host A, and can I do it using a single command, or do I need to run three commands (one for each port, 80,443,902)?

• Apache internal test servers

  - by user74274

  I want to build a test system in the office. On one box I will install XAMPP. I will put a website that I want to test on that box. Now I do not want it connected to the Internet. So my plan is to use a reverse proxy to resolve things like ads and other external links. So I am thinking of using mod_proxy for that. Now my question is, How many boxes do I need? 1 for Xampp, 1 for mod_proxy and 1 for the server where mod proxy redirects them to. Total of three. But maybe I could do it with less. Can I run Mod_proxy on the first box? Is there a better way? Thanks

• Retrieving Chrome History and History Archives for Mac

  - by Justin

  I've read some articles here that suggest that we are able to retrieve Chrome's history as SQLite databases: Export history from chome browser How can I view "archived" Google Chrome history — i.e. history older than three months? I can't seem to find the folder where these are supposed to be located. In the first article, the provided path was ~/Library/Application\ Support/Google/Chrome/Default/History, but there is no such directory in my filesystem. I am using Chrome 26.0.1410.65 on Mac OS X Lion. And I am signed in with my Google account. Article http://unlockforus.blogspot.it/2008/09/how-opening-google-chrome-files-history.html provided in the last of the above is very useful, but it is only for Windows. Is there something similar to that but for Mac? Is there a way to find the folder where Chrome stores my history?

• RAIDZ vs RAID1+0

  - by Hiro2k

  Hi guys I just got 4 SSDs for my FreeNAS box. This server is only used to serve a single iSCSI extent to my Citrix XenServer pool and was wondering if I should setup them up in a RAIDZ or a RAID 1+0 configuration. This isn't used for anything in production, just for my test lab so I'm not sure which one is going to be better in this scenario. Will I see a major difference in speed or reliability? Currently the server has three 500GB Western Digital Blue drives and it's dog slow when I deploy a new version of our software on it, hence the upgrade.

• Trouble with Windows 7

  - by vtimmerm

  Hi, I'm trying to virtualize an application for Windows 7 but am running into trouble: Application will run fine in Windows 7 if installed in the base. When it is virtualized, it will run on XP, but not on Windows 7. I have tried this in three ways: Captured on XP with ThinApp 4.0 Captured on XP with ThinApp 4.5 Captured on Windows 7 with ThinApp 4.5 Even when captured on Windows 7, it will not run on Windows 7 but will run on XP. When captured with a rival product, Altiris SVS, the virtualized app runs fine on Windows 7. Any idea's what could cause this behaviour? Looking at the trace file, you see that they are different right from the start when comparing Windows 7 and XP tracefiles. What could cause it to go in completely different directions? (And why does the tracefile on Windows 7 say: Operating System Unknown? Does everybody have that on Windows 7 even with 4.5?) The error message is: "Object variable or with block variable not set". Thanks, Vincent

• HP ProCurve GVRP Setup

  - by Matt

  I'm trying to setup GVRP on my 4 ProCurve switches. Currently I have a Layer 3 3500yl-24G (J8692A) which is connected to 3 Layer 2 2510G-48 (J9280A). I have three trunk ports setup on the 3500 connected to the 3 switches and currently everything seems to be working, the devices are talking to eachother and GVRP is pushing its configurations from the 3500 to the 3 other switches. My question is, once GVRP is setup, how exactly do I configure the ports on the 3 L2 switches to use the correct VLAN? I'm new to ProCurve network equipment and this is much easier to setup on Cisco equipment.

• Terminal Services - what does this message mean ?

  - by southof40

  Hi - I'm responsible for a W2003 server. I'm trying to switch on terminal services. When I do so I get a message that includes the text : "If you continue with this installation, programs that are already installed on your server will no longer work and will have to be reinstalled" Surely that doesn't mean what it appears to mean ? I just want one extra person to be able to access the machine in the same way that currently two administrators do (via "Remote Administration") only I want all three to be able to do simultaneously. When I bought the extra TS license I thought I was just buying the right to have one extra user. Is doing this really going to trash everything on the machine ?

• MySql Replication with a star topology

  - by Riotopsys

  My company currently operates in 3 separate locations connected by slow vpn links. Each site hosts a dedicated MySql server. I need to aggregate the data from all three of them onto a single server for corporate reporting. The powers that be have stated I cannot use circular replication or federated tables. Is there a third party tool for MySql that can replicate from multiple masters? Basically the diagram would be a daisy with the reporting server slave at center with multiple replication connections coming in from the master sites on the petals.

• Why would Firefox not be able to visit Google anymore?

  - by Edward Tanguay

  Lately I've noticed that my Firefox Browser was taking a long time when I would search Google, e.g. 3 seconds before I would see any results. If I search for a three-word phrase, it just hangs trying to connect: I removed all add-ons but it still does this. I thought it might be something with my router, but Chrome, Safari, Opera and Internet Explorer all work fine. Bing works fine in Firefox. Here's my Firefox version information: Otherwise I can still use Firefox, e.g. I'm using it to post this question, but I do notice that when I browse with it, images are often "broken" for a split second before they appear, as if it is having a hard time pulling them from a remote server. Other browsers don't do this. What could be causing Firefox to hang when searching Google?

• Paste multiple lines before a line in vim?

  - by Umar

  How do I copy multiple lines and paste them as a block before a line? As an example I have the following code and I want to copy and paste the three lines after the if statement to after the else statement but before the line below it. [row col] = find(H); if (nargin < 4) delqmn = sparse(row, col, 0, M, N); % diff of msgs from bits to checks delrmn = sparse(row, col, 0, M, N);% diff of msgs from checks to bits rmn0 = sparse(row, col, 0, M, N);% msgs from checks to bits (p=0) else // Insert 3 lines after if statement here qn0 = 1-r;% pseudoposterior probabilities qn1 = r;% pseudoposterior probabilities Thanks

• What is the difference between Windows RT and Windows Phone 8?

  - by Rakib Ansary

  From what I have read it seems there are more or less three versions(?) of Windows 8: Windows 8, Windows RT, and Windows Phone 8. While the difference between Windows 8 and Windows RT is clear, I don't understand the difference between Windows RT and Windows Phone 8. The Android parallel, Jelly Bean that runs on Tablets and on Phones doesn't have any differences. Are there any differences between Windows RT and Windows Phone 8 except for the fact that one is for Tablets (Windows RT) and the other is for Phones (Windows Phone 8)?

• Error when trying to add additional mailbox in Outlook: The name could not be resolved

  - by user640

  I am trying to open an additional mailbox in Outlook 2003 for one of my users. She already has three additional mailboxes in the list (found in the advanced account settings), and these work fine. When I click the "Add..." button, it immediately reports: The name could not be resolved. The action could not be completed. This is before I am prompted for the name. We're using an externally hosted Exchange 2007 server. How do I resolve this?

• UDP flooding multiple servers

  - by Chris Gurney

  What do you suggest? Being UDP flooded as I write to multiple servers in different data centers in 5 different countries . Up to 250,000 packets a second. I believe Cisco routers 5505 would not handle that - (some of our datacenter hosters can offer them. Some have no firewalls to offer.) Our clients naturally have constant disconnects to the server they are on. Hacker started this about three weeks ago. Sometimes for a few hours - up to a few days. If we can't stop it hitting the server with firewalls then how do we stop the hacker - now there is the challenge! Update : Found some of the data centers offer up to 10 firewall rules but would their routers be able to handle the possible volume I am talking about? Thanks Chris

• coordinating a script to run on only one of identical load-balanced servers

  - by Amos Shapira

  I have two identically configured CentOS 5 servers (possibly more in the future). I need to run a cron job on any one of them and that it'll run only on one of them. I know about RedHat Cluster Suite (we use it on other servers), but it's a too big a gun to use for this task, plus it doesn't really behave well for less than three nodes. Is there anything light-weight I can use for that? The servers can communicate with each other directly. I suppose I can develope something over ssh or nrpe (two server which are already installed on these servers), but I was wondering whether there is something already available.

• Vim is spellchecking in XML files where I don't want it to, and only there

  - by Kazark

  I'm trying to use Vim's builtin spellchecking in some XML documents. This happens merely by having the XML syntax loaded, as seen in the following minimalistic example (which reproduces what I also see in large XML documents): Note that given two buffers with exactly the same content, when Filetype is text, the spellchecking works; when it is xml, it does not. spell is set in both buffers. However, given this view of the top three lines of a large XML document, you can see that the spellchecking is certainly on: but it is only checking attributes. The nuisance is that none of the things it is actually finding are mispelled, and it isn't finding any of the numerous misspellings in the document. I would like it at a minimum to find the spelling errors in the body of the document, and being able to turn off the checking on attributes would be a nice option. I've searched for @NoSpell in the xml.vim file, but that returns no hits.

• How Can I Automate the Backup of a Quickbooks Server?

  - by Nick

  I have three computers: The first is the company file server which has the Quick Books company file, is always on, and lives in the closet. The other two are Quick Books Clients. All are XP Pro. I need a way to automatically backup the QB data file, without any user intervention. Quick Books has a built in scheduled backup utility, but from what I've read, it only works when the software is running in single user mode. (and obviously putting the server into single user mode defeats the concept of having a server). Also, I'm not actually running QB itself on the server, just the "QB Database Server" process that sits in the system tray. Surely there must be a way to automate this? I'm open to any ideas/suggestions. Thanks!

• HP DL380 RAID5 Mistake

  - by Eddy

  I had drives fail in both logical drives on a server. When I replaced failed 146GB drive in Raid 5 array with four (4) 146GB drives. On reboot the Smart Array controller asked if I wanted to accept data loss. Guess mistake to choose yes. Can't seem to find a way to get system to repair RAID5 but it seems to want to just create a new partition. Is there anyway I can go back and get the system to restore the data from other three drives now that I said accept data loss?

• Mercurial SSH process blocks when run from Local System

  - by Liedman

  We are using Mercurial over SSH for our development. We use Hudson for continous integration, and have deployed it on Tomcat, running on a Windows 2003 Server using the Local System account. Mercurial is configured to use Putty's plink.exe as its ssh command in Mercurial.ini, together with a private key for SSH authentication. When Hudson attempts any Mercurial command over SSH, the operation just blocks. I can see the three processes being started: hg.exe, cmd.exe and plink.exe. On the remote machine, I can also see the SSH session being opened and the authentication key being accepted. After that, nothing appears to happen, and everything just blocks, seemingly forever. (As a side note, subversion/SVN over SSH works from Hudson to the same server, using the same user and authentication key). A solution would of course be the best, but at least a hint for how I should debug it to get further would be nice, since I'm stuck and haven't even got an error message right now.

• How to monitor CPU usage and performance on a Hyper-V server with several VM's

  - by Bjørn

  Hello, I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system. I have set up three Virtual Machines, all running Windows 2008 32 bit. Build server, running Team City Staging server SQL Server, running SQL Server 2005 I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.) So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

• network timeout how to analyse problem

  - by elhombre

  In the last three month I was experiencing that my internet connection started to get very slow and websites had long time to load. The first thing I made was an ping to www.google.com which showed that I was loosing pakets. Here some of the results: 64 bytes from 74.125.39.103: icmp_seq=2909 ttl=53 time=48.222 ms Request timeout for icmp_seq 2910 Request timeout for icmp_seq 2911 64 bytes from 74.125.39.103: icmp_seq=2912 ttl=53 time=44.372 ms Days later I had to reset my router because it wasn't able to establish a correct network connection. It was after the reset when things worked again for some days. But later the same network timeouts started to happen again. I would like to know how I can analyze the problem to get to the source which is causing this timeouts. Which steps do you take to circle in this Problem?

• Multiple Ubuntu Server SSH Connections

  - by Craig Smith

  I'm trialing a ubuntu server 12.04 LTS to replace a Windows Server that I use but I have got a little stuck with SSH I'm currently able to SSH into the server but I need to have multiple persistent SSH connections as I have at least 3 applications that need to run in the server and still be able to access their terminals to issue commands to the applications. At the moment this is fine if I use the physical terminals of the machine as I can just jump between the three terminals I use but remotely doing this is the issue. As I'm not entirely familiar with this side of linux I'm not sure if this is even possible to do or how to even get around this issue.
