• hardware leasing vs purchase

  - by musoNic80

  I'm wanting to get a new laptop and desktop. I'm self-employed and so both bits of kit are primarily for business use. I've been looking into leasing both computers as an alternative to purchasing outright. Does anyone have any experience of this? I'm UK based and have found a company called hardsoft which seem to offer a good service. I'm particularly attracted by the upgrade after 18 months option and the fact that the machines are under warranty for the lift of the lease. I'd be really grateful for general thoughts, especially if there are any UK users or hardsoft clients.

• SSL certificate for Oracle Application Server 11g

  - by Easter Sunshine

  I was asked to get an SSL certificate for an "Oracle Application Server 11g" which has a soon-to-expire certificate. Brushing aside the fact that 10g seems to be the newest version, I got a certificate from InCommon, as I usually do without problem (except this is the first time I supplied Oracle Application Server 11g as the software type on the CSR form). On the email containing links to download the certificate, it mentioned: Certificate Details: SSL Type : InCommon SSL Server : OTHER I forwarded the email over to the person responsible for installing it and got a reply that the server type must be Oracle Application Server for the certificate to work (the CN is the same as before). They were unable to install this certificate (no details provided to me) and mentioned they had this issue previously with Thawte when they didn't supply Oracle Application Server as the server type. I don't see any significant difference between the currently installed certificate (working) and the new one I just got signed by InCommon (not working). $ openssl x509 -in sso-current.cer -text shows, with irrelevant information ommitted.

• Can't get virtual desktops to show up on RDWeb for Server 2012 R2

  - by Scott Chamberlain

  I built a test lab using the Windows Server 2012 R2 Preview. The initial test lab has the following configuration (I have replaced our name with "OurCompanyName" because I would like it if Google searches for our name did not cause people to come to this site, please do the same in any responses) Physical hardware running Windows Server 2012 R2 Preview full GUI, acting as Hyper-V host (joined to the test domain as testVwHost.testVw.OurCompanyName.com) with the following VM's running on it VM running 2012 R2 Core acting as domain controller for the forest testVw.OurCompanyName.com (testDC.testVw.OurCompanyName.com) VM running 2012 R2 Core with nothing running on it joined to the test domain as testIIS.testVw.OurCompanyName.com A clean install of Windows 7, all that was done to it was all windows updates where loaded and sysprep /generalize /oobe /shutdown /mode:vm was run on it A clean install of Windows 8, all that was done to it was all windows updates where loaded and sysprep /generalize /oobe /shutdown /mode:vm was run on it I then ran "Add Roles and Features" from testVwHost and chose the "Remote Desktop Services Installation", "Standard Deployment", "Virtual machine-based desktop deployment". I choose testIIS for the roles "RD Connection Broker" and "RD Web Access" and testVwHost as "RD Virtualization Host" The Install of the roles went fine, I then went to Remote Desktop Services in server manager and wet to setup Deployment Properties. I set the certificate for all 3 roles to our certificate signed by a CA for *.OurCompanyName.com. I then created a new Virtual Desktop Collection for Windows 7 and Windows 8 and both where created without issue. On the Windows 7 pool I added RemoteApp to launch WordPad, For windows 8 I did not add any RemoteApp programs. Everything now appears to be fine from a setup perspective however if I go to https://testIIS.testVw.OurCompanyName.com/RDWeb and log in as the use Administrator (or any orher user) I don't see the virtual desktops I created nor the RemoteApp publishing of WordPad. I tried adding a licensing server, using testDC as the server but that made no difference. What step did I miss in setting this up that is causing this not to show up on RDWeb? If any additional information is needed pleas let me know. I have tried every possible thing I can think of and I am just groping around in the dark now. The virtual machines running on testVwHost The configuration screen for RD Services The Windows 7 Pool The Windows 8 Pool This is logged in as testVw\Administrator

• django fcgi - call a management command with subprocess.Popen

  - by user41855

  Hi, I'm using an app called django-chronograph. It has a code of line which works in my dev environment and does not work in production: p = subprocess.Popen(['python', get_manage_py(), 'run_job', str(self.pk)]) This line crashes in production with: unknown command run_job Whereas when I run directly from command line: manage.py run_job It works fine. Interestingly it worked once when we exchanged 'python' with 'usr/bin/python'. then we restarted the server once more and it was back to old behaviour. Thus it seems as we have a python path issue. I'm not the guy who is running the server, its my app that should run and it would be great to get some help here. Attention: I'm a total noob regarding server-administration.. server environment: NGINX with FCGI-Daemon FCGI in prefork-mode

• Monitoring System for the cloud?

  - by Maxim Veksler

  I need a monitoring system, much like ganglia / nagios that is build for the cloud. I need it to support : Adding / removing nodes dynamically. (Node shuts down, dose not imply node failure...) Dynamic node based categorization, meaning node can identify them self as being part of group X (ganglia gets this almost right, but lacks the dynamic part...) Does not require multicast support (generally not allowed in cloud based setups) Plugins for recent cool stuff such as Hadoop, Cassandra, Mongo would be cool. More features include: External API, web interface and co. I've looked at Ganglia, munin and they both seem be almost there (but not exactly). I would also go for reasonably priced Software as Service solution. I'm currently doing research, so Suggestions are highly appreciated. Thank you, Maxim

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks

• [xUbuntu] Move a window back into the visible area?

  - by Johan

  Hi I have this annoying little problem on my laptop that sometimes after I have used a external monitor (with higher resolution) some applications place them self outside the visible area of my desktop. So the question is how do I move them back into the visible area? (please note that no part of the window is visible so I can't use the mouse) Is there some app that can give me focus to move a application to the mouse pointer or something like that? Please note that I'm running xUbuntu (xfce) on this laptop. Thanks Johan

• install grub on pendrive containing linux installation, making it system independent

  - by arpit

  i have a win7 system and i want to install debian 6 on usb flash drive. the problem is grub loader. i want to install the grub loader on usb itself, so i can just plug in the pendrive in any computer and boot to deb6. so in effect making the flash drive an independent system. i tried it earlier, but ended up with grub loader needing me to insert the pendrive every time to give me boot options to even boot the win7 system, even though it was on primary hdd. so is there a way to turn the pendrive into full linux system with own boot loader, which can automatically detect os in the system i plug it in and be able to boot any of them. totally, self sufficient and system independent; making the pen drive so that it only needs a host system to run the os it carries. thank you, waiting for replies.

• DNS failover across multiple datacenters?

  - by Jae Lee

  I've got a site that is starting to get a lot of traffic and just the other day, we had a network outage at the datacenter where our loadbalancer (haproxy) is hosted at. This worried me as despite all my efforts of making the system fully redundant, I still could not make our DNS redundant, which I think isn't an easy solution. Only thing I was able to find was to sign up for DNS failover from places like dnsme, etc .... but they cost too much for budding startups. Even their Corporate plan only gives you 50 million queries per month and we use that up in a week. So my question is, are there any self hosted DNS we can do that provides the failover like how dnsme does it?

• Create and use intermediate certificate authority on Windows Server 2012?

  - by Sid

  Background: Server OS is Windows Server 2012. GUI is installed as we come upto speed with powershell. Setup is staging, not production (yet). We have our (internal, domain limited) Root CA installed. I would like to take the Root CA offline to secure storage but before that I'd like to setup an intermediate CA which can take over actual live, online (int-RA-net) functionality Can someone guide me covering: creating the intermediate CA certificate request installing the intermediate CA certificate on domain controller (certification authority role already installed with Root CA online right now) use the intermediate CA to generate a certificate (any use certificate, just for demonstration purposes) Obviously this certification chain would be invalid on computers outside our domain (self trusted root - our root certificate is NOT from common 3rd parties). This last point is NOT a problem.

• How do I share a complete XP disk so it can be seen from a Windows 7 system?

  - by Ian Ringrose

  This should be easier! (both computers can see the internet etc so I know the network it’s self is working) I have a normal home network with a Windows XP machine on it and the new Windows 7 (64 bit) machine. So I can transfer the files to the new Windows 7 machine, I wish to share the complete disk (and all files) from the Windows XP machine and access them from the Windows 7 machine. Is there a step by step set of instructions for doing this anywhere? So fare I have: put both computers into the same workgroup put the windows 7 machine into work network mode so it can see the XP machine in the work group shared the XP disk as read only But when I try to access a lot of the folders on the XP disks, I am told I am not allowed to access them. (I was not asked for any passwords by the windows 7 machine when I accessed the XP machine. The XP machine just has its default account with no password set on it)

• UCARP: prevent the original master from taking over the VIP when it comes back after failure?

• Slow Starting DHCP Client Service - HP Thin Clients

  - by Ryan

  We have recently began adding XPe thin clients to our domain in preperation for a new citrix environment. One thing that has been picked up on in testing is that they appear slow to boot. The issue manifest's it's self as the classic "Applying Computer Settings..." screen we are all used to seeing. After digging into the issue it appears the DHCP Client service is taking some time to load on boot, this varies but I would estimate it can take around 1 minute in some cases. I've eliminated the classic issues, DHCP is responding correctly and in quick time. DNS is not the cause and GPO's are applying promptly. A simple workaround is to assign the client a static IP which work's great so the TCP/IP servies are obviously firing up quickly, just not DHCP Client. Does anyone have any idea's on how I may be able to improve the service start time? Keen to find a better solution before I get my arm twisted into setting up 250 thin clients with static addressing!

• How to manage a home-grown YUM package repo?

  - by TomOnTime

  There are plenty of websites that explain how to manage a mirror of YUM repos. I want to run a repo for my home-grown packages. Is there a good way to manage such repos? What I need to do: Manage 3 repos: unstable, testing, stable Self-service functions that let users add/remove/promote packages (promote means moving a package unstable?testing or testing-stable). ACLs that control which users/groups may add/remove/promote packages. Automatically re-sign packages as they move repo to repo (since the GPG key for "stable" should be different than "unstable") Automatically run "createrepo" to update repodata when needed. Suggestions?

• How to write a ProxyPass rule to go from HTTPS to HTTP in IIRF

  - by Keith Nicholas

  I have a server which is running a web app that self serves HTTP. I'm wanting to use IIS6 (on the same server) to provide a HTTPS layer to this web app. From what I can tell doing a reverse proxy will allow me to do this. IIRF seems like the tool to do this job. There are no domain names involved.... its all ip numbers. So I think I want :- https:<ipnumber>:5001 to send all its requests to the same server but on a different port and use HTTP ( not exposed to the net ) http:<ipnumber>:5000 but not sure how to go about it with IIRF, I'm not entirely sure how to write the rules? I think I need to make a virtual web app on 5001 using HTTPS? then add a rules file.

• How can I change how OS X's 'say' command pronounces a word?

  - by jwhitlock

  OS X's say command is useful for some tasks (such as Skype's 'notify me when a contact comes online), but it is pronouncing some names incorrectly. Is there a way to teach say to pronounce a word differently? For example, try: say "Hi, Joel Spolsky" The 'ol' sounds like 'ball' rather than 'old'. I'd like to add an exception that say "Pronounce Spolsky like this", rather than try to teach new linguistic rules. I bet there is a way since it can pronounce "iphone" as Apple wants. Update - After some research, here's what I've learned: Text-to-speech is split between turning the text to phonemes, and then the phonemes are turned into audio using a voice. Changing the voice doesn't effect the phonemes. The Speech Synthesis Manager has some functions for turning text to phonemes, and a method for registering a speech dictionary that will add new text-phoneme maps. However, Apple's speech dictionary must be in a binary form - I didn't find any plist XML. Using dtrace while running say, I found some interesting files opened in /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources. This is probably the speech dictionary, but they are all binary, except for Homophones, which is XML. Adding entries to Homophones does nothing - it is probably used in speech-to-text. They are also code signed by Apple - changing them may prevent some programs from working. PrefixDictionary CartNames CartLite SymbolDictionary Homophones There are ways to add text versions of application interface elements so VoiceOver works, a lot of which a developer gets for free, but there are tricky bits. The standard here appears to be to use a phonetic spelling as needed. My guesses are: say is a light layer of code on top of the Speech Synthesis Manager. It would be easy for the Apple devs to add a command line option to take the path to a speech dictionary plist for alternate phoneme mapping, but they didn't. It may be a useful open-source project to write a better say. Skype probably uses Speech Synthesis Manager directly, leaving no hooks to change the way my friend's names are pronounced, other than spelling them phonetically, which is silly. The easiest way to make a command line version of say is how JRobert suggested. Here's my quick implementation, using Doug Harris's spelling suggestion: #!/bin/sh echo $@ | tr '[A-Z]' '[a-z]' | sed "s/spolsky/spowlsky/g" | /usr/bin/say Finally, some fun command line stuff: # Apple is weird sqlite3 /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources/Tuples .dump # Get too much information about what files are being opened sudo dtrace -n 'syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0)); }' # Just fun say -v bad "Joel Spolsky Spolsky Spolsky Spolsky Spolsky, Joel Spolsky Spolsky Spolsky Spolsky Spolsky" echo "scale=1000; 4*a(1)" | bc -l | say
