• Azure VM : Connection refused by host

  - by Simon Kérouack

  I recently stopped a subscription with 14 VMs in it and restarted it a few days later. Now all my VMs are working just fine at the exception of 6 used for MongoDB. They respond to ping and so they show as online in the azure dashboard but they do not answer to anything else. I tried (from different locations, in and out of the azure cloud) ssh : connect to host * port *: Connection refused telnet : Unable to connect to remote host: Connection refused mongo : exception: connect failed The ports for ssh and mongo are opened in azure. I tried restarting the VMs a few times trough the azure dashboard, they seem to restart successfully but still refuse all connections. I already looked for similar issues and the best solutions I found was to wait... the issue has been happening for 7 days and waiting is no more an option.

• Automatic driver search & update on Windows?

  - by Ben

  I have a Dell laptop issued by my employer, and I always find it a real pain to search for, download and maintain their drivers. It baffles me that there does not seem to be a nice way (product, website, ...) to just download the stuff you need, without hassle. The same goes for the other Windows based laptops in my direct environment. Are there any (preferably free) automated solutions available? Or do you have a nice workflow - other than searching the manufacturers website - to help smoothing this process?

• Setup local EC2 style cloud?

  - by John Kramlich

  I was recently given 3 dual opteron 2400 servers with 4GB of RAM and 120GB hard drives. I am interested in setting up something similar to Amazon's EC2 for my own personal web development use. Basically, I would like to spin up instances from an ISO or other disk images and have them available to test and develop software. Are there open source solutions I can use to accomplish this? I am assuming one of the machines will need to act as a controller of some sort for the other two. I use Sun's VirtualBox on my local development machine to virtualize various versions of Microsoft Windows. However, I'm not sure if that's the best tool for what I am trying to achieve. I apologize in advance if this question is to vague to get meaningful responses. I am new to cloud computing and fairly new at server administration.

  - by user1664417

  Currently Im facing an issue when Im trying to connect any usb flash drive to my pc. ok, below is what happens to me: 1) I can connect usb keyboard and mouse without any issue. 2) however when i connect usb flash drive, there are 2 situations that are occuring randomly a) there is no usb drive mount in my computer, when device manager is checked, it shows error code 10, but is shown in disk management. b) my computer will have usb drive mounted, but when I click on it, it is empty. on right click the properties, the disk space show 0.

• Backing up a Linux VPS with RSync to Vista

  - by Frank

  I've been working to setup a Linux VPS to host a couple of Wordpress sites and eventually a Mercurial server. I've setup one site and things have gone well. However, before I start moving other things to the VPS, I need to setup a backup solution. My provider, Linode, suggest RSync (among a couple of other options) to do backups. I've seen a few posts on this site that suggests other backup solutions including going to the Amazon Cloud but that costs money and the VPS is all the money I want to spend on this for the time being. So, to help solve that I want to have my backup computer be my home desktop computer. Assuming I'm using RSync, is it possible to use my Vista based home computer to become the destination for the backup? And if it is possible, what type of command or connection would I need to configure on the vista machine? Any insight would be helpful. It's probably obvious, but I've never used RSync.

Our spam policy suspends ANY user/customer that gets 10% bounced . We currently rotate our outgoing Mail Ip once deliveries limit per remote host is reached. Is it the best approach/solution ?

• HTTPS and HTTP issue on server with SSL

  - by Asghar

  I have a site www.example.com for which i purchased SSL cert and installed. And it was working fine, I also have a subdomain with app.example.com which was not on SSL. Both www.example.com and app.example.com are on same IP address. At later we decided to put SSL only on app.frostbox.com and then i configured SSL with app.frostbox.com and it worked fine, Now the issue is that Google is indexing my site as https://www.example.com/ and when users hits the web , Invalid security warning is issued and when user allow security issue they are shown my app.example.com contents. Note: I have my SSL configuration files in /etc/httpd/conf.d/ssl.conf The contents of the ssl.conf are below. NOTE: I tried solutions in .httaccess but none of those worked. Like redirecting 301 redirects etc http://pastebin.com/GCWhpQJq

• Recommend a web file sharing software please.

  - by Baczek

  I'm looking for a web platform to put company files at. My requirements are: should be accessible via a browser should be open source must be installable (dropbox is a no-go) must have an option to put a access time limit on a file must perform garbage collection automatically after a file expires must be able to mark files as public or private an option to protect a file via a pin-code for users without accounts in the system would be nice to have The problem is I don't even know what to search for - all my googling results in either complete groupware solutions or p2p file sharing software. If such a thing doesn't exist, please don't hestitate to say so, so I can crawl to a corner and cry myself to sleep. TIA

• Proper way to connect SATA and IDE Hard drives together?

  - by Bartek

  I have an old IDE hard drive that has a broken Windows install on it. It just won't boot up, and I've tried a variety of solutions. That's fine, I really just need a few files on the hard drive. I have a computer that uses a SATA connected hard drive. It's a working PC. I would like to connect the old IDE hard drive to that compute and basically browse through the file system, grab the files, and copy them to my existing computer. My problem is with my few attempts to connect the IDE drive I would get Boot Disk Failures and so forth. I guess it's trying to boot from the IDE but I'm not really sure. Any help would be appreciated, Thanks!

• NATing with a single-homed machine possible?

  - by Harry

  I have the following setup: a) a single-homed machine, A, that can see the Internet. b) other machines B, C, and D that cannot see the Internet. c) A, B, C, and D can see each other. d) all machines are running either RHEL 5.3 or Fedora 16. Question: Is it possible to have B, C, and D share the Internet connection with A somehow? Note, again, that machine A does not have a second NIC installed. (The solutions that I am finding on the Net assume A to be a dual-homed system!) Also, could you please recommend a set of book(s) or online resources for a current and in-depth coverage of iptables for people with only a basic knowledge of TCP/IP?

• DNS Help: Move domain, not mailserver

  - by Preserved

  I'm in the middle of launching a new website for an already-in-use domain. The domain has a complicated email system so we'd like to move that over to the new server a bit later on. Currently the domain DNS is managed by the current webhost. I plan on moving the DNS management back to Network Solutions, then point the A record to the new website's IP. However, currently the DNS has the MX record the same as the A record. When NetworkSolutions is managing the DNS, and I point the A record to the new IP, then the MX record can't be the A record.. Right now: A Record mydomain.com points to IP address 198.198.198.198 MX record mydomain.com points to IP address 198.198.198.198 What I want: A Record mydomain.com points to IP address of new server MX record somehow points to current existing mailserver Does this even make sense?

• .bashrc doesn't get sourced after su'ing to root

  - by Ian Dunn

  I've got a CentOS 5.6 VPS and both root and my normal user account have identical copies of a .bashrc file in their home directories. The file contains a few basic aliases, etc. If I login to root, root's copy gets sourced. If I login to myuser, myuser's copy gets sourced If I su to root after logging into myuser, then all the aliases, etc inside myuser's copy get removed, and root's copy doesn't get sourced. If I then manually source root's copy, the command completes without any errors, but none of the aliases's etc get applied. I've searched Google and Server Fault, but haven't found any solutions. Does anyone know how to fix that?

• Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

  - by bensch

  I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.

• Windows (7 & Vista) laptop monitor does not come back after closing lid

  - by Scott Vercuski

  I'm experiencing an issue with Windows Vista (and now Windows 7) with my laptop. When I close the laptop lid the monitor goes blank but will not come back on after I re-open the laptop. The screen stays blank and nothing that I do will get it to come back. The laptop is an HP DV9000 series. Has anyone else ran into this issue? One of the solutions I've seen online is to go into the device manager and replace the lid driver with something nonsensical (the website suggested pointing the driver at the sound recorder). This does solve the problem by disabling the lid but doesn't really resolve the root issue. I'm asking if anyone has any method I can use to debug what's going on. How do I tell if it is an operating system issue vs. a malfunction within the lid itself. I'd actually like the lid to function as it's meant to. Thank you!

• Why does Snow Leopard report incorrect battery levels for Bluetooth input devices after switching them to Apple rechargeable batteries?

  - by GeneQ

  I have a Magic Trackpad, Magic Mouse and the Apple Wireless keyboard. They work fine. Two days ago, doing my part for the environment, I changed all their batteries to Apple rechargeable batteries. Today I noticed that the battery level meter for all three devices report the wrong battery level. The trackpad reports 93% charge, the keyboard 75% charge and the mouse 65% charge. This can't be right; these are fully charged new batteries. They can't possible drop that much within 48 hours. Has anyone else encountered this problem? And are there any solutions?

• Reccomendation for tuning 100's of SQL Databases

  - by wayne

  I'm running several SQL servers, each running a few hundred multi-gig databases for customers. They are all setup homogeneously as far as the schemas are concerned, however customer usages of the data differ quite a lot from database to database. What would be the best way to auto-index/profile/tune this large amount of databases? As there are at least 600 or more catalogs I cant have someone manually profile, and index as required by each databases usage patterns. I'm currently running SQL 2005 but will be moving to 2008, so solutions that work with either are fine.

• Recently reloaded computer, now have trailing effect when windows overlap

  - by Tony

  I recently did a clean install of my home machine and I am having a weird graphical error where if I move one window across the top of another it leaves a trail: I have the most recent NVIDIA drivers installed and nothing new is installed on my machine than before the reload (and I never had this issue before). I have two monitors and it happens on both so I'm sure it isn't a hardware issue (the card and my main monitor are also both less than 6 months old) I've also noticed a ripple when scrolling down on web pages which I believe is related. Any ideas what might be causing this and solutions to fix it?

• Creating encrypted database for work

  - by Baldur

  My boss posed this problem to me: Encrypted: We need an encrypted database for miscellanious passwords we use at work that are currently only in people's head. Easily accessable: Someone needs to be able to quickly access specific passwords, possibly at hectic moments. This requires any sort of public key management (keeping it on a USB key in a sealed envelope?) to be relatively easy. Access control: The system should have groups of passwords where only specific people have access to specific groups. Recoverability: We need to make sure passwords from one group aren't lost even if the only users with direct access quit or pass away—hence we need some way where (for example) any two members of senior management may override the system (see the treshold link below) and retrieve all the passwords with their key. The first thing that jumped into my mind was some form of threshold and asymmetric cryptography but I don't want to reinvent the wheel, are there any solutions for this? Any software should preferrably be free and open-source.

• Rendering artifact when using Eclipse (FlashBuilder)

  - by Demian Brecht

  Once in a while when using FlashBuilder, I'll get a rendering artifact that doesn't go away until I do a full reboot. This artifact seems to be caused by a popup triggered by code documentation popups (hovering over keywords) that linger after the popup has been dismissed: This behavior is seemingly random and incredibly annoying. It only happens when using Eclipse (although I don't run many Java-based programs) and run an NVidia Quadro 2000M (with the latest drivers - figured I'd try that before posting). Has anyone else encountered this issue? Any known solutions?

• Excel: How do I copy hyperlink address from one column of text to another column with different text?

  - by OfficeLackey

  I have a spreadsheet where column A displays names in a certain format. There are 200-odd names and each has a different hyperlink (which links to that person's web page). I want to reformat the name order so it is "Surname, Name" rather than "Name Surname" and retain the hyperlink in the newly formatted column. I have achieved "Surname, Name" easily by splitting the names into two columns (using LEFT and RIGHT formulae) - forename and surname - then I have a new column with a formula to return "Surname, Name." However, the hyperlinks are not in that new column and I need them. I don't want to do this manually, for obvious reasons. I cannot find a way of copying just hyperlinks from column A without copying the text from column A. So, effectively, what I need is some sort of macro to take, for example, the hyperlink from A2 and copy it to H2, with H2 still retaining the updated ordering of name. I don't have the knowledge to write this myself, so would appreciate solutions.

• Setting up a simple proxy

  - by waiwai933

  I'm going to China for a week, and I'd prefer to be able to watch YouTube while I'm there. Since it's blocked, I presume I'm going to need a proxy. I have a Mac and a Linux box at home that I can use, but I'm not sure how complicated setting up a proxy is. From what I understand, I should be able to do it with a browser that supports HTTP 1.1 CONNECT if I connect to my machine at home. Can I do this, and if so, what browser can I use, or if I have misunderstood something, do I have any other simple solutions?

• Automatically copy files out of directory

  - by wizard

  I had a user's laptop stolen recently during shipping and it was setup with windows live sync. The thief or buyer's kids took some photos of themselves and they were synced to the user's my documents. I had just finished moving the users files out of the synced my documents folder when I noticed this. Later they took some more photos and a video. I wrote up a batch script to copy files out synced directory every 5 minutes into a dated directory. In the end I ended up with a lot of copies of the same few files. Ignoring what windows livesync offers (at the time there was no way to undelete files - I've moved onto dropbox so this ins't really an issue for me) what's the best way to preserve changes and files from a directory? I'm interested in windows solutions but if you know of a good way on a *nix please go ahead and share.
