  • determine the archetecture of a mac from the command line or script?

    - by Brian Postow
    I'm writing a shell script, and I need to know the archetecture, ie PPC or Intel. Back in the day, there was a program /bin/arch that told you, but my mac doesn't seem to have it... Is there an easy way I can do this? Grep for something in a logfile? call some other program that spits that out as a side effect? It would be nice to know what OS Version I'm running too, but that may not be necessary. thanks

  • Determine compression ratio for Windows compressed drive

    - by munrobasher
    Is there a Windows 7 native way to display the overall compression ratio on a Windows compressed drive? As part of our disaster recovery process, we're copying some key system folders onto 2TB external hard drive, encrypted using TrueCrypt and copied using robocopy. The drive is compressed and I'd like to see what kind of compression ratio we're getting and whether it's actually worth the performance overhead. I know that TreeSize can possibly do this (as mentioned in another post) but want a OS native way if possible. Thanks, Rob.

  • How much CPU use is too much?

    - by Jonathan Sampson
    I've got a server that receives around a million unique visitors a month and I've recently began using Plesk to help monitor some of the vitals on the box itself. RAM I can make sense of, but I'm not really sure if my CPU usage is too high, low, or about average for this number of visitors. The server exists solely to serve up a somewhat hefty WordPress blog. This is one week. What types of things should I look out for? Some other information about this server follows: VCPU(s): 4, RAM: 6GB, HDD: 30GB, OS: Ubuntu Server 10.04 x86_64

  • Thunderbird 3.0.2 stops automatically checking for email

    - by Chris
    Since upgrading to Thunderbird 3.0.2 on Mac OS X 10.6, Thunderbird will intermittently stop checking for messages automatically. Frequently I am presented with the error "This folder is being processed" when manually checking for mail. Restarting Thunderbird fixes the problem, but I have noticed hours can go by where auto checking isn't working, and restarting shows there were dozens of messages waiting to be delivered in that down time. Occasionally I will see "indexing 1 of 2 messages - 0% complete" in the status bar, it will sit there for a long time. Actions I've taken to fix: Deleted all .msf files in all accounts Removed News & Blogs account Staggered the "automatically check for mail" interval for each account Worth noting: after waking up the macbook, TB usually needs to be restarted to resume auto checking for mail. Has anyone experienced such trouble?

  • What Computing/Programming Qualifications should I aspire for

    - by indevel
    I am a computing science post graduate in my first job from after my degree. During my 12 month review my boss posed the question "What can we do for you in terms of progressing your career?". This got me thinking, after university I hadn't really thought about what other qualifications were available. So this is my question, what courses/qualifications should I be looking to do. Which are highly regarded and which would be really useful to complete. I've searched Google it but all I see is a jumble of courses with no idea of the credibility of each. Any help is much appreciated. I'm traditionally a systems architect, but with this job I've turned to more embedded work so Id like to edge towards electronics, embedded programming, real time OS to help with my work also it would be more likely to be accepted if it was related to my job. Finally UK based courses/ qualifications are a must as travel is probably out of the question. Help me grow as a programmer.

  • Installing maven on Ubuntu by manual download

    - by WebDevHobo
    To install Maven, I downloaded the latest version from the website and then followed these steps: http://maven.apache.org/download.html#Installation The last step, the version control, does not work. It says that 'mvn' is currently not installed and that I should type sudo apt-get install maven2 If I go directly to the mvn file itself, it does work: root@ubuntu:~# /usr/local/apache-maven/apache-maven-2.2.1/bin/mvn --version Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700) Java version: 1.6.0_21 Java home: /usr/java/jdk1.6.0_21/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux" version: "2.6.32-25-generic" arch: "i386" Family: "unix" So, what am I doing wrong here? Or what would and apt-get install do extra that I might have forgotten?

  • Is it a good idea to take onsite/offsite backups of server images?

    - by ServerAdminGuy45
    Assuming a non-virtualized environment it a good idea to take actual images of servers (using something like Acronis True Image) and store them on\off site? Backing up data is great but I feel it would be good to have copies of OS images in the event hardware dies or an upgrade gets botched I can always revert back. What would be your recommended way to do this (preferably using a NAS and an online backup service)? I was talking with the Iron Mountain folks and the service they described is more geared toward taking incremental snapshots of data. I'm not sure if there's a way to backup images in an incremental way such that only the changes between them are saved (that way I'm not wasting X GB each time I take an image).

  • How to mount a network drive?

    - by Relik
    Ok so I'm trying to set-up a home file server. I'm thinking about just setting it up as an FTP server, no particular reason other than I'm familiar with FTP and samba tends to be very frustrating. Basically the set-up I'm going for, is to be-able to create multiple user accounts for the server and restrict or allow access to specific folders on each user. FTP is the only way (that I know of) to accomplish a set-up like that. My question is how can I mount an FTP server as a drive in Ubuntu so that all my applications can access it just like any other driver or folder. An example would be downloading 12.10 via torrent when it comes out, I would like to be able to tell transmission to just download the file straight to my ftp server. I know how to do this in Windows, its actually very easy. But I cant figure it out in Ubuntu. I have tried using the "connect to server" option in nautilus, and it works, but it doesn’t give me the result I want, most applications don’t see the folder, while others can. Also I am open to options other than FTP if anyone has any suggestions. I've looked into FreeNAS but that doesn’t seem to allow me to control the user accounts the way I want to. Then after all is said and done I would still need a way to mount the shares as a drive in Ubuntu. The ability to mount network drives in windows is one of my favourite features, but seeing how Ubuntu is now my daily OS and has been for about 4 years, I really need a way to accomplish the same thing in Ubuntu. Also a GUI would be preferable, seeing as there will be multiple people using this server, I would like it to be as easy as possible. EDIT: this link here seems to be almost exactly what I'm wanting to do, if I could find a GUI that can do this ill be almost set. then I would just need to find a way to hide specific folders from certain users.

  • Workflow: Deploy Operating Systems

    - by Owen Allen
    The Deploy Operating Systems workflow is a workflow document that we added recently. It shows you how to get operating systems up and running in your environment. It's mostly linear, but it's a bit more complicated than some of the others. It's built around a pair of images. In both images, the left side shows the prerequisites for the whole process. Before you can deploy operating systems, you have to have Ops Center fully installed, with libraries set up and hardware already discovered. Once you've done that preparation, the first image walks you through all of the OS deployment steps. First you discover existing operating systems, then you provision Oracle Solaris 10 or Oracle Solaris 11. If you're not planning on using virtualization, then your deployment is done, and you're directed to the operate workflows. If you are interested in virtualization, though, you go on to the second image: The second image walks you through deploying virtualization, sending you to the Deploying Oracle Solaris 10 Zones, Deploying Oracle Solaris 11 Zones, or Deploying Oracle VM Server for SPARC workflows, depending on what kind of virtualization you're planning on using. Once you've done that, you're ready to go on to the operation workflows.

  • Files in /home deleted

    - by long-time user....2006
    In the most specific, unemotional terms: Reinstalled os, using 11.10(1 month after release to skip initial issues that usually crop up). Configured system to my specifications(just ways of organizing config files, etc). Log out Log back in after after an hour or so...to find my home directory obliterated and just a few skeleton files existing. think oh well, try again (this has happened before with an install for reasons I've never been able to pinpoint, usually around install time with some sort of update but its never been a major recurring issue) same thing happens I thought something was awry, so I reinstalled again (another 20 minutes, meh) Set up system, arranged home directory a bit differently thinking maybe I tread on something I shouldn't have. log out, come back --- the same thing. Most of the directories I added were deleted (e.g. .xmonad which links to xmonad.hs in my portable config directory) tl;dr every change I make in my home directory gets deleted. The emotional part: UNACCEPTABLE. I need to configure my system the way I want, not get punched in the face everytime I make a change. I'll willingly fill in details as needed, this was just a start to see if anyone can help, I've found no trace of this issue in a search.

  • Why does Resource Monitor in windows 7 show half my memory as "Hardware Reserved"?

    - by Brandon
    Does anyone know why in Windows 7 Resource Monitor shows that I have 8 GB of RAM installed on my computer, but I only have 3.2 GB available as 4.8 GB are in "Hardware Reserve". I researched this issue and tried going into msconfig and making sure that in the boot options the number of processors and max memory options were turned off. I also opened the computer up and reseated each of the memory sticks while clearing out any dust that was in there. Some info on the system I am using: OS: Windows 7 Enterprise 64-bit Edition CPU: AMD Phenom X4 9750 Memory: 4 X 2GB DDR2 memory Motherboard: MS-7548 (Aspen) Any help would be much appreciated.

  • Toshiba recovery disc doesn't give me all partition options

    - by ACarter
    I'm trying to install Windows XP on a new machine, by way of the original Toshiba XP recovery disc. (I can use a recovery disc on not-the-original machine can't I?) When I boot up with the disc in, I get to a point when it asks me how I want to install. I select the 'existing partition' option. It then gives me a dialog saying it will install into the SYSTEM partition, which is tiny. Obviously I don't want to overwrite SYSTEM, so how can I install XP on one of my empty partitions (already created)? I know it's possible to install the OS from the CD on a separate machine (just tried in a virtual one). Maybe I can move the partitions around if it just selects the first one?

  • XAMPP on windows 7 not working

    - by 404Error
    Hey there, I just installed XAMPP lite on Windows 7. I have two drives - C: for the OS and regular files, and an external drive E:. I insatlled XAMPP lite on E: (on the root), and its been giving me problems. Apache works well enough, but MySQL doesn't work. When I go to http://localhost/phpmyadmin/, it gives me the following error: Error MySQL said: #2003 - Can't connect to MySQL server on 'localhost' (10061) Connection for controluser as defined in your configuration failed. Any ideas as to what could be the problem? I used the zip file for XAMPP lite, the 32 bit version. This is on Windows 7 Home premium. Thanks!

  • Looking for an open source real-time network analysis program

    - by JrSysAdmin
    Can somebody recommend an open source real-time network analysis program? What I'm looking for the program to do is display a graph of bandwidth usage by IP within our internal network that can quickly be viewed any time we need to (typically when we want to quickly find out who is utilizing high amounts of bandwidth and slowing down the network). We ideally simply want to hook up a monitor on the wall of our server room to a system whose NIC will be in permissive mode to log all network activity in a visual manner which can easily be seen and running 24/7. Prefer open source as I do not have a budget for this project and prefer open source projects in general. I'd also prefer for this to be available for CentOS but any linux distro or Windows OS would be acceptable. Thanks!

  • Pressing 'Enter' doesn't really work in Firefox

    - by inkedmn
    When I'm typing just about anywhere in Firefox on OSX and press enter, it simply doesn't do anything. This includes typing in a textarea element (which should take the cursor to the next line), in a search form (which should submit the form). I'm typing this very question in Firefox right now and I'm unable to advance the cursor to the beginning of the next line. I have no clue what I did to make this happen, but it's kinda driving me insane. This is Firefox 3.6.3 under Mac OS X 10.6. Thanks!

  • Any benefit of /home Ubuntu partition

    - by nightcrawler
    I want to have dual OS of Win8 & Ubuntu 12.10. Provided that Ubuntu can access ntfs partition of Windows but same can't be said about Windows this leads to a question mark on the significance of having /home partition while installing Ubuntu. As far as I know /swap & / are the two partitions directly used by Ubuntu to store programs, installation & stuff while the documents/media resides in /home. Now because Ubuntu releases are more frequent than Windows & updates needs backup & relate stuff, so I came to decision to not to use /home at all, rather keep all my documents/media in ntfs, which would be untouched while upgrading Ubuntu as Win updates are once in a decade! Is my thinking correct? If yes, what would be the minimum space I should allot to /home plus how much I should allot to / one must know that I plan to use heavy applications like Maple, Matlab & Sagemath on Ubuntu.

  • Real time audio streaming

    - by Josh K
    I have a remote computer running OS X. I would like to stream the audio from the microphone input over the network so I can listen to it. Primarily I want to do this because I'm out of the office but still need to communicate with people there. I would like to use VLC, but am not fully aware of the options available. I tried SoundFly (as recommended by another answer) but this didn't seem to want to connect. At this point I should note that I'm using a VPN network to connect to the remote computer (using Hamachi). I can open up ports / etc fine though, so I should be able to do this. Alright, I found Nicecase which does exactly what I want but I would prefer to not have to shell out $40 for it.

  • Best practice for administering a (hadoop) cluster

    - by Alex
    Dear all, I've recently been playing with Hadoop. I have a six node cluster up and running - with HDFS, and having run a number of MapRed jobs. So far, so good. However I'm now looking to do this more systematically and with a larger number of nodes. Our base system is Ubuntu and the current setup has been administered using apt (to install the correct java runtime) and ssh/scp (to propagate out the various conf files). This is clearly not scalable over time. Does anyone have any experience of good systems for administering (possibly slightly heterogenous: different disk sizes, different numbers of cpus on each node) hadoop clusters automagically? I would consider diskless boot - but imagine that with a large cluster, getting the cluster up and running might be bottle-necked on the machine serving the OS. Or some form of distributed debian apt to keep the machines native environment synchronised? And how do people successfully manage the conf files over a number of (potentially heterogenous) machines? Thanks very much in advance, Alex

  • How to install software packages on a Mac? (MacPorts, Fink, anything better?)

    - by Ben Alpert
    On my Mac OS X machine, how would you recommend I install command line software and other packages? I've been using MacPorts and it always seems quite slow, presumably because it has to compile the packages on-the-fly. I'd much prefer a package management system that has binary packages, saving me the need to compile things every time I want to download something new. I think Fink has binaries for some of the packages, but I usually see MacPorts recommended as the system to use. Which do you think works better and why? (Or is there another system that I haven't heard of?)

  • Partition tool with console UI (as in server installation)?

    - by lepe
    Back in 2006, Ray (3DLover) posted the same question in: http://ubuntuforums.org/showthread.php?t=309680 but none of the answers were really useful. Now with a little help from AskUbuntu community, I would like to repeat his question again to see if this time it can be answered correctly. So this is the question (and what I wish too): I'm looking for a UI tool for managing partitions in a console. I have installed Ubuntu Server, so I don't have X Windows at all. fdisk and sfdisk are entirely command line. parted is slightly better, but it's not really a UI. cfdisk has somewhat of a UI, but it only works on one disk at a time, and there's no advanced options like configuring LVM or RAID. Just partitioning. I love the partition tool that is available during the OS install procedure. You can partition, configure RAID's and LMV sets. It can format the partitions with several different file systems, it can set labels, mount options and it can insert your volumes into your fstab. Is this tool available as a stand-alone program? I can't find it anywhere. I think it's called parted_server, but I can't find much information about where to get it. In the past, I have run the Ubuntu install procedure just to use the partition manager that comes with it. (canceling the install after making my partition edits) Anyone help me on this? Thanks -Ray Thanks in advance.

  • Choosing hardware for Flash Media Server

    - by minaev
    Having read the answers in this discussion, I still would like to come up with the same question: What should I buy to run Flash Media Interactive Server 3.5? I just have slightly different boundary conditions. We plan to serve video to ca. 1,000 users simultaneously. It will be live stream, so the server will receive the stream in HD (1280x720), cache it, reformat to various other resolutions and send it to users. OS of choice is Linux, but if you say it should MS-DOS, so it will be... What would be a decent server for this task?

  • How to specify which GCC for MacPorts to use?

  • why Apache with ssl but back end weblogic without ssl works?

    - by huangli
        Hello everyone. my question is very simple . The link below is a picture about my architecture. https://docs.google.com/open?id=0BxSXbpgYIZVOR212RVk4ZDN1Sm8.      The pic above shows the architecture right now and it works correctly ! which means I could visit apache with url https//apchehost:8080, could not visit the web app with https served by weblogic but I could visit these app with https served by Apache(Apache is proxy server).      My question is why the Apache is configured with ssl but weblogic without ssl works ? I think weblogic should also configured with ssl . If this works , what about security level ? Is the ssl really works if only Apache configured with ssl but Weblogic without it ? Thanks . condition: Apache 2.2.17 with weblogic module mod_wl_22.so Weblogic: 10.3 OS: Windows server 2003
