  • Understanding exim configuration files

    - by bobobobo
    So, I want to understand what's going on with this Exim configuration directory. In /etc/exim4, there's: * exim4.conf.template * update-exim4.conf.conf * conf.d The conf.d has a mess of directories and files, and inside each are a bunch of if statements which I find really different. For example: maildir_home: debug_print = "T: maildir_home for $local_part@$domain" driver = appendfile .ifdef MAILDIR_HOME_MAILDIR_LOCATION directory = MAILDIR_HOME_MAILDIR_LOCATION .else directory = $home/Maildir .endif .ifdef MAILDIR_HOME_CREATE_DIRECTORY create_directory .endif .ifdef MAILDIR_HOME_CREATE_FILE My question is, where do the CAPS VARIABLES get defined how can I change them why are there so many if statements in these configuration files?

  • HTTP, TCP, UDP and connectionless

    - by user132199
    I am a bit confused with HTTP lately. Some facts are that TCP can operate connection orientated or connectionless this I understand. TCP though is connection-oriented while UDP is connectionless which is used when the message itself can be fit into a single message. Question: If HTTP uses TCP, and TCP provides reliable conjnections for multiple message excahnge, and HTTP is said to be connectionless then how is this possible? TCP is connection-oriented? So how is HTTP connectionless????

  • How do you close a VMWare Fusion VM Window without shutting it down or suspending it?

    - by Chris
    There are a few parts to this question. The first is: I'm running a virtual machine guest using vmrun and nogui, when I open the VMWare Fusion application, the window library opens but subsequently also opens any window of a running VM. Is there a way to prevent this? Secondly, but related: Once it does pop up or I have that separate VM Window open, is there a way to close the window such that it does not suspend or shutdown the vm i.e. convert it back to nogui mode?

  • When is a secondary nameserver hit?

    - by Evan Carroll
    Take this scenario: domain: foobar.com ns1: 2.2.2.2 ns2: 3.3.3.3 My question: Is ns2 hit just in the event that ns1 is down? Or, is ns2 hit any time that ns1 returns a miss/doesn't resolve the query? I know ns2 would be hit if ns1 ever went down; but, what if ns1 is up and just doesn't have the data?

  • Protecting Backups from Viruses

    - by Frank Thornton
    Currently we are using ReadyNAS RN102 by NETGEAR to hold all our images from all our machines. My question is can viruses expand from the machines and infect the NAS drive and the backups? We are using AOMEI Backupper. EDIT: Basically, I want to keep my clean backups clean. I keep Daily, Weekly, Monthly achievable backups, my worry is a virus might attempt or try to infect these backups making using them worthless.

  • How to restore Google "Cached" links?

    - by Steven Penny
    On Google search, "Cached" links are available, which take you to a version of the page saved on Google servers. These links are quite useful if the source page is temporarily down or otherwise. Back in July 2011 Google moved these links inside of an "Instant Preview" box. Many people from this thread and others either simply cannot find the new links or prefer the old location. Edit To be clear, the question is how to restore the links to the old location.

  • What is the best log rotator for Python wsgi applications ?

    - by Low Kian Seong
    I am running a wsgi based application that has concurrent users accessing it. For my logs needs I tried logrotate but found that logrotate is not too friendly to Python applications, so I tried using RotatingFileHandler and even worse found my logs all chopped up and part of it went missing! I am considering ConcurrentRotatingFileHandler, my question is, has anyone out there experienced the same thing and better yet do you have any battle tested solution for Python wsgi, concurrently accessed applications?

  • How to re-enable Autoplay for removeable drives on Windows 7

    - by Clay Nichols
    When I plug a USB thumb drive into my Win7 PC, it no longer auto-launches the window giving me options like "Import Photos" or "browse". The drive is recognized but nothing autolaunches. Similarly, CD's don't autoplay either. I verified that Win7 is set to autoplay, per method 1 and 2 of: http://www.sevenforums.com/tutorials/27544-autoplay-enable-disable-autorun.html FYI, there is a similar question (but for Windows XP) here on SU.

  • Windows Server 2008 R2 bare metal restore to different hardware

    - by S Falken
    Scenario: I have a Windows Server 2008 R2 x64 installation whose main disk drive is now 7 years old and showing signs of age. For the last couple of months it's been displaying increased errors and requirements to run checkdisk. I have successfully created a bare metal restore (BMR) image on a separate data drive on the server, which can be seen from the Windows Recovery console; I tested it by booting to and using the Windows Server installation DVD's recovery utilities. The BMR image includes the system drive with boot partition, system state, and the D:\ drive of the server, which is where I have followed the practice of installing any program that does not require a C:\ installation path. Therefore, the BMR includes both the C:\ and D:\ drives, system state and boot partition. The C:\ drive is a 7-year old Seagate 160GB. The D:\ drive is a rather newer 120GB Western Digital. I have purchased a 128GB solid state Samsung 830 that I want to restore these partitions to, using the BMR. Questions: In the above-referenced article, Microsoft seems to be indicating that I am only able to restore to like-kind hardware, which doesn't help at all and is difficult to believe. Is this really true? I've cleaned these drives up and minimized the size of partition they require. C:\ will need about a 70GB partition, and the data on D:\ will need about 50GB. Will Windows Server backup allow me to restore the BMR to newly-created partitions on the SSD, discarding extra space? I don't need a "how-to": I just need an "is it possible". Justification: Before posting this question, I checked ServerFault articles with the following titles, but none of them were about this exact scenario: Restore SBS 2008 Backup to Same Hardware but Different Disk Configuration Restoring Windows Server 2008 to different hardware - OEM License Restoring II6 server after a hardware failure windows 2008 r2 fail to restore Domain controller failed to restore using windows backup tools How does restore to dissimilar hardware work? Migrating Windows 2008 R2 from a PC to a different PC TFS 2005 Server restore from one hardware to another I also researched Microsoft but only received an oblique answer which was not precisely aimed at my question, at the following URL: http://support.microsoft.com/kb/249694#method3

  • Wifi channel interference

    - by artfulrobot
    In my neighbourhood there are: 11 wifi signals on channel 1 2 wifi signals on channel 4 (including mine at the mo) 8 on channel 6 6 on channel 11 According to the diagram on wikipedia Mine on channel 4 will suffer interference from channel 1 and channel 6, so a total of 20 other networks(!). So would I be better to join channel 11, even though my network is then in direct competition with the 6 others? I suppose the question is: what's worse: direct interference (meaning that on the same channel) from 6 or fringe interference from many more networks?

    This is just a general question. I started working from home a few months ago and i find the hardest part is trying to keep track of what I'm working on and how much time was spent. I do both programming and network admin work. Is there any software packages (free) out there that some of you use?

  • Future raid update in a NAS and HP ProLiant alternatives

    - by edwardmlyte
    I'm thinking of buying the HP ProLiant MicroServer*. My question is if I just put a single 2TB drive, how easy would it be in the future to upgrade to a second 2TB drive in a RAID-1 setup? Can this be done without formatting the original 2TB drive? *It looks like the £100 cashback offer is stopping end of Aug, making this system cost around £260 without HDDs. Are there any other brands that anyone would recommend for all-in-one hardware solutions.

  • Running Radius on a Novell Backbone

    - by YsoL8
    Hello I am a rookie network engineer and I've been asked to create a secure wireless system intergrated with an existing network. So far I'd decided to use 802.1x secuity with a Radius enabled server over a Novell backbone. My question is: does Novell still support this type of server setup? I heard rumours it is at the end of it's supported life and I'd like some confirmation. Also can I get some recommendations on better backbone / server providers. Cheers

  • Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

    - by Warren P
    Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

  • Emergency response CMS

    - by mmcglynn
    I have been asked to do some investigation regarding an emergency website response scenario, a critical situation that would bring quintuple website traffic to 30K visits a day for a few days. No one wants to use our current CMS for this, but rather WordPress or something else. The obvious, a static HTML page is out. I have a separate research track for optimizing WP, so my question is, is there a hosted, easy to use CMS that can handle huge traffic? Like Squarespace but for enterprise.
