  • Inexpensive, simple screen recording application for mac

    - by donut
    I am more and more consistently running into the need to create screencasts (record my screen) for clients to show them how to use programs or websites. Up until now I've been using Jing and it's been wonderful. But I would like something that can give me something less annoying than a .swf. A .mov or, best of all, something that plays without fuss on Mac and Windows. Also, the 5-minute limit is annoying, but not show stopping. Basically, I'd like to be able to actually give them the file on a CD or something instead of relying on whatever host I use staying up for eternity. To sum up, here's what I require: Record a portion or all of the screen. Records audio from mic while recording screen. Exports files easily playable on Mac and Windows (requiring Quicktime is okay, but not ideal) Will work on Mac OS 10.5+ Allows recording videos of at least 5 minutes. Text in recorded videos is easily readable when exported. Bonuses points for: Records videos greater than 5 minutes Exported videos will work in Windows Media player without any fuss. I haven't upgraded to Snow Leopard yet but I know it has some screen recording stuff built in but I don't know if it would be sufficient or not. The reason I say, "simple" is because most of the applications I've seen do much more than I need (I mean, Jing is nearly perfect for my needs) and cost more than I would like to spend.

  • How To Fix Samba File Permission Issues in Mac OSX

    - by user1867768
    I've had this problem for a long time, here is the basics of it... I use a mixed environment of Windows 7/8 computers with Mac OSX Lion/Mountain Lion. Whenever a Windows computer creates a file on a SMB share on the Mac it no longer has group permissions, only the person who created or updated it can access it. My solution has been to go onto the Mac system and reset permissions for the entire directory structure then everyone can see it again. About the only thing on this that I can find was for OSX pre Snow Leopard that mentioned editing the SMB.CONF file to fix their particular problem (similar to mine, http://www.gladsheim.com/blog/2009/09/19/osx-leopard-and-samba-permissions/). The problem is that now Lion and Mountion Lion no longer have an SMB.CONF file (another web search pointed to the com.apple.smbd.plist (http://kidsreturn.org/?s=smb.conf) but it's an XML file now and I'm not clear on what should be done to THAT to fix the problem. So, short of me writing an Applescript to run every hour to fix permissions, does anyone know a solution to this very frustrating problem? Thank you in advance for any advice or solutions you can offer!

  • SSH-forwarded X11 display from Linux to Mac lost after some time

    - by mklein9
    I have a new and vexing problem with ssh forwarding my X11 connection when logging in from a Mac (10.7.2) to Linux (Ubuntu 8.04). I have no trouble using ssh -X to log in to the remote machine and starting an X11-based application from that shell. What has recently started happening is that additional invocations of X11 applications from that same shell, after a while (on the order of hours), are unable to start because the forwarded display is being blocked (I presume). When attempting to start xterm, for example, I get the usual message about a bad DISPLAY setting, such as: xterm Xt error: Can't open display: localhost:10.0 But the X11 application I started right when I logged in is still running along just fine, using that exact same display (localhost:10.0), just that it was started earlier. I turned on verbose logging in sshd_config and I see this in the /var/log/auth.log file in response to the failed xterm startup attempt: sshd[22104]: channel 8: open failed: administratively prohibited: open failed If I ssh -X to the server again, starting a new shell and getting assigned a new display (localhost:11.0), the same process repeats: the X11 applications started early on run just fine for as long as I keep them open (days), but after a few hours I cannot start any new ones from that shell. Particulars: OpenSSH sshd server running on Ubuntu 8.04, display forwarded to a Mac running Lion (10.7.2) with the default Apple X server. The systems are connected on an Ethernet LAN with a single switch between them. Neither machine is running a firewall. Until recently (a few days ago) this setup worked perfectly so I am mystified as to where to look next. I am by no means an X11 or SSH expert but have good UNIX/Linux experience. Nothing obvious has changed in either client or server configuration although I have tried changing a few options to try to debug this, like setting sshd_config's TCPKeepAlive to no, and setting "host +localhost" (you can tell I've been Googling). When logging in from a Linux 11.10 laptop to the same remote host over the same network and switch, this problem does not occur -- an xterm can be invoked successfully hours later from the same ssh login shell while the same experiment from the Mac fails (tested this morning to be sure), so it would appear to be a Mac-specific issue. With "LogLevel DEBUG3" set on the remote machine (sshd server), and no change made in the client connections by me, /var/log/auth.log shows one slight change in connection status reports overnight, which is the port number used by the one successful ssh session from the Linux machine (I think), connection #7 below: sshd[20173]: debug3: channel 7: status: The following connections are open:\r\n #0 server-session (t4 r0 i0/0 o0/0 fd 14/13 cfd -1)\r\n #3 X11 connection from 127.0.0.1 port 57564 (t4 r1 i0/0 o0/0 fd 16/16 cfd -1)\r\n #4 X11 connection from 127.0.0.1 port 57565 (t4 r2 i0/0 o0/0 fd 17/17 cfd -1)\r\n #5 X11 connection from 127.0.0.1 port 57566 (t4 r3 i0/0 o0/0 fd 18/18 cfd -1)\r\n #6 X11 connection from 127.0.0.1 port 57567 (t4 r4 i0/0 o0/0 fd 19/19 cfd -1)\r\n #7 X11 connection from 127.0.0.1 port 59007 In this report, everything is the same between status reports except the port number used by connection #7 which I believe is the Linux client -- the only one still maintaining a display connection. It continues to increment over time, judging by a sequence of these reports overnight. Thanks for any help, -Mike

  • Mac Share Points automatically authenticate with matching Windows AD credentials from Windows

    - by Ron L
    I recently started administering an OS X server (10.8) that is on the same network as our AD domain. While setting up Mac Share Points, I encountered some odd behavior that I hope someone can explain. For the purposes of this example assume the following: 1) Local User on OS X Server: frank, password: Help.2012 2) AD Domain User: frank, password: Help.2012 3) AD Domain: mycompany 4) OS X Server hostname: macserver (not bound to AD, not running OD) When joined to the domain on a a Win 7 computer and logged in as frank and accessing the shares at \\macserver, it automatically authenticates using frank's OS X credentials (because they are the same). However, if I change frank's OS X password, the standard Windows authentication dialog pops-up preset to use frank's AD domain (my company\frank). However, after entering the new OS X password, it will not authenticate without changing the domain to local (.\frank). Basically, if a user in AD has the same User name and password in OS X, it will authenticate automatically regardless of the domain. If the passwords differ, authenticating to the OS X shares must be done from the local machine. (and slightly off topic - how come an OS X administrator can access the root drives on the Mac server from Windows when accessing the Mac shares even when they aren't shared? In other words, it will show all the shared folders from "File Sharing" plus whatever drives are mounted in OS X)

  • Setting up a localhost mail server on Mac OSX

    - by Thom
    I asked this over on stackoverflow. They pointed me here. I would love to be able to test php webapps that require emailing registration info etc. on my mac. I downloaded a version of CommuniGate Pro. I need to mail either to an account inside or outside (whichever is best) of the localhost. Again this would be used for testing purposes to verify and debug my code prior to uploading to a hosting service. Any ideas, help and/or examples would be very much appreciated. If it would be easier I could go over to Windows XP. That would just mean setting up wamp and transfering my files over from the mac side via dropbox. I got the local mailserver to work so I can send emails between accounts. However, I cannot seem to get the php code to work. I know that I am missing something. I see where this has been asked before. I want to add that I am using xampp. In Mac OS 10.6.8. I tried changing the php.ini SMTP command to macintosh-3.local. <?php function email($to, $subject, $body, $headers) { $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'From: <[email protected]>' . "\r\n"; mail($to, $subject, $body, $headers); } ?>

  • Mac and L2TP VPN no problems, xp, vista and 7 no go :s

    - by The_cobra666
    Hi all, I've got some weird problem and I'm out off options. The situation: When connecting from my mac to the VPN server (Windows Server 2003 R2) with L2TP PSK, everything works like it should. However, when I connect from a Windows PC, nothing happens. it spits out error 809 and sometimes 789. Now I know that my ports are OK, since the mac can connect without any problems. It's the same for: XP, Vista SP2 and 7. None can connect. If I connect to the VPN server directly (to the internal IP instead of WAN from the router), it connect's without a problem. Connecting using PPTP works... now if only L2TP would work thank you very much Windows! I have checked the counters on my linux router with iptables -L -nv and they do not raise when connecting. Not on ACCEPT and not on DROP. Only when connecting from the mac. I've found the guide from Microsoft to enable: AssumeUDPEncapsulationContextOnSendRule in the registery. I have set it to "2", on the server and client. Still no go. After that registery key it started giving me error 789 instead of 809. The IPSEC services are running on the client and server. Is there anyone that ppleease can help me with this! I've been working on this for 2 days and I'm out of options. Thanks!

  • Mac OS X Lion (10.7) Drive Encryption

    - by Skoota
    My iMac has two drives (a 256 GB solid-state drive, and regular 2 TB hard drive). The Mac OS X Lion system is installed on the solid-state drive and, like many other users, I have moved my user profile folder onto the secondary 2 TB drive. However, as you may be aware, FileVault 2 on Mac OS X Lion (10.7) only encrypts the system drive. This leaves my data drive (containing my user profile folder, with all of my data) unencrypted. I am aware that work arounds for this issue exist (such as https://github.com/jridgewell/Unlock) but I am not happy with the results since they involve decrypting the data drive on startup using a LaunchDaemon (before any users have logged into the computer) essentially meaning that any user who logs onto the computer will see the unencrypted drive. I would like a method which will only unencrypted the data when an authorised user logs into the computer. As such, is there a way to do one of the following? Encrypt the entire data drive and only decrypt the drive when an authorised user logs into the computer. This would be equivalent behaviour to the Lion FileVault 2 feature, but on a secondary drive rather than the system drive. Encrypt only the user profile folder on the data drive, and only decrypt the folder when the user logs into the computer. This would be equivalent to the behaviour of FileVault 1 on previous versions of Mac OS X? I am happy to pay for a commercial third-party product that provides the required feature(s), but I have not yet been able to find one. Thanks in advance for any assistance.

  • VMWare Fusion cannot connect to the NAT connection on my Mac

    - by FFish
    I have been using VMWare Fusion on my Mac to check out my websites on localhost. Now I can't connect anymore with the NAT connection. There seems to be a problem with my IP address or Mac address? I have no idea what causes this, it was working fine before!? In the XP (SP2) VM, in the taskbar I see the Local Area Connection with the yellow warning icon. The bubble says: "This connection has limited or no connectivity. You might not be aisle to access the Internet or some network resources. For more information, click this message." Doing that opens up the Local Area Connection Status panel. In the Support tab, when I click the repair button I get following message: "Windows could not finish repairing the problem because the following action cannot be completed: Renewing IP address." I tried disabling my firewall and also XAMPP that I use as server on OSX. VMWware version: 3.1 VM: XP SP2 Mac OSX 10.6.3 Any help would be greatly appreciated.

  • v2v of RHEL5 box - issues with retaining MAC address

    - by Alex Berry
    For the last week we have been troubleshooting a customer's Red Hat Virtual Machine running on ESXi. We've been using Veeam to try to create a replica off-site and have been having getting it to work on a decent schedule and recently we noticed that there were issues with orphaned snapshots while looking at the datastore. You can see several snapshots in the same folder and it's causing issues with replication and backup, so we decided the cleanest way was to v2v the machine to another datastore so that we had a clean single-vmdk setup to work with, this is where our trouble started. We first started off with a v2v using vmware converter and connecting to the powered on machine as we were having issues doing an offline v2v. This copied fine but when I tried to set a static MAC using this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=507 the new VM wouldn't take the address, it simply obtained a new MAC, received a dhcp lease and then would only boot up to a blank red screen, never the login screen. So the next step was to do an offline v2v, once we finally got it working. Same thing, followed the kb to the letter and still it wouldn't take the MAC. I then tried it again and upon completion I compared both old and new VMX file, copying every identifier and variable possible, then unregistered both VMs, uploaded the new VMX file and booted, only to see the same results. Finally I did the same as above but I copied the disk using DD to a second attached vmdk and then attached this to the new VM, and still no luck. After downloading the modified VMX file after the first boot and comparing it to the original I created I found that the bios uuid had changed from the one I typed in manually, so I'm assuming this may be the snagging point, but I have no idea. I've never had this issue before on a P2V and I'm just wondering if someone could shed some light on this, maybe it's to do with RHEL licencing?

  • Mac, VNC and multiple monitors

    - by MarqueIV
    I asked a similar question here before but apparently I wasn't as clear as I had expected by the responses. That said, I'll try again. I have a Mac Pro with quad monitors which I would like to access remotely. I've been using VNC for this (either via screen sharing or a dedicated VNC client), which works, but the VNC protocol matches the physical layout/resolutions of attached monitors. One of the things I like about Microsoft's Remote Desktop (Terminal Server) client is that when you connect, it blanks out the local screens and sets the resolution to a client-specified setting. In other words, when natively running Windows, even though I'm running a physical 30" monitor flanked by 2 24" monitors as well as a 21" Cintiq monitor, I can set the Remote Desktop resolution to match my notebook's screen giving me a native, single-monitor configuration. As soon as I disconnect (and you log back in locally), the desktop un-blanks and the resolution resets back to the four physically attached monitors. Again, VNC works and yes I know I can use 5901, 5902...n to attach VNC to a specific monitor as opposed to the entire desktop, but I'm still at the mercy of trying to look at a 2560x1600 resolution on a 1280x800 screen. I'm left with either scaling (everything's too small) or panning/scrolling (it's like playing hide-and-seek with your documents!) SO... anyone know of any Mac-based remote software (client and server) that will let me connect to my Mac Pro and reset the resolution by the client, just like you can in Windows, or am I SOL?

  • Looking for way to log process terminations on OS X (Mac)

    - by Stan Sieler
    I'm looking for a way to log all process terminations on my Mac (OS X 10.6.8). (And see pid, timestamp, process name) I've implemented something similar for HP-UX, but it required a kernel-level driver and intercepting several variations of "exit()" (the normal one, and the one invoked on behalf of a process while it's aborting). Why do I want the info? I've been seeing messages in my system log file (dmesg) like: CODE SIGNING: cs_invalid_page(0x1000): p=91550[GoogleSoftwareUp] clearing CS_VALID CODE SIGNING: cs_invalid_page(0x1000): p=92088[GoogleSoftwareUp] clearing CS_VALID Although dmesg lacks timestamps, apps/Utilities/Console : Database : all : search for CS_VALID shows that the messages appears about once every 58 1/2 minutes. I suspect the number after "p=" is a process id (pid) ... but for a process that has long since terminated by the time I see the message. So, if there was a process termination log mechanism that recorded the pid, the time of termination, the reason for termination, and the process name (at time of termination), that would probably allow me to determine who's causing those errors to be logged! (No, I'm not running Chrome on my Mac, and "ps -ef | grep -i goog" gets no hits either ... I'm not consciously running any Google apps on the Mac) thanks, Stan [email protected]

  • Windows Vista/7 dropping Mac Server share points

    - by Hooligancat
    My Windows Vista and Windows 7 clients are having problems maintaining access to SMB shares on a Mac server. The initial connection to the server appears to be OK, as the Windows clients can see all of the server share points. However, the client randomly drops a couple of the server share points although the clients can still see the server. For example. If I have the following share points on the Mac server: Share A Share B Share C Share D Share E The Windows client can see these shares most of the time and can access them most of the time. But randomly a couple of the shares will just get dropped or go missing from the Windows client's ability to view them so I end up with something like: Share B Share D Share E All the share points are established int the same way with the same permission settings. My Mac OSX Server is set up with the following for SMB: SMB sharing enabled Standalone Server Workgroup of `CORPORATE` Allow Guest Access = YES Client connections limit = 100 Authentication: NTLMv2 & Kerberos and NTLM Code Page is Latin US (437) This is a workgroup master browser WINS registration is set to Enable WINS server (tried with setting off) Enable virtual share points for homes YES I noticed in my SMB file service log that the clients appear to connect OK, but I get the following error which implies a reset by either the server or the client: /SourceCache/samba/samba-187.9/samba/source/lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.0.99. = Connection reset by peer I am a bit stumped as to a direction to turn to try and get this to resolve. Continued attempts to access the server from the client will reconnect to the share points, but they inevitably get dropped again in the near future. Any and all help much appreciated.

  • VPN sharing on Mac OS X 10.5 machine

    - by Jens
    I have a rather weird problem. I want to share a VPN connection that has been established by my Mac OS X 10.5 computer with another machine in my network. This is what I did: In the /etc/hostcongig file on the main computer I added the line: IPFORWARDING=-YES- I assigned a fixed IP address to my computer (192.168.178.30), a fixed one to the other machine (192.168.178.60) and my computer's IP address as gateway on the other machine. I connected to my VPN using the internal Mac OS X VPN client (PPTP connection) I run this script: #!/bin/sh natd -same_ports -use_sockets -unregistered_only -dynamic -interface ppp0 -clamp_mss ipfw -f flush ipfw add divert natd ip from any to any via ppp0 ipfw add pass all from any to any sysctl -w net.inet.ip.forwarding=1 Source: Using (and sharing) a VPN connection on your Mac Now everthing works smootly, however speed is an issue. I get 1,8 MBit/s on my main machine and only 0,3 - 0,6 MBit/s on the other one. My question: What could possibly be wrong? Do I have to tweak MTU settings, is there any packet inspection ongoing that needs time....? Any help appreciated!

  • Viability of Mac OS X 10.9 Time Machine Server in office environment

    - by user197609
    Currently we have about 20 Mac OS 10.9 MacBook Pros (almost all with SSDs) backing up to individual USB drives. I'd like to consolidate these to one drobo thunderbolt drive array attached to a Mac Mini server (running 10.9 server) using time machine server. My question is, will this scale to 20 users? Examples I have seen seem to be 5 or 6 users tops, and this isn't easy for me to test (I'd rather not ask everyone to backup to the array and then switch back to USB drives if it brings our network to its knees). My primary concern is saturating our gigabit network, as time machine backs up every hour for every machine, so there would usually be a couple people backing up at any given time. We also have some people occasionally on our 802.11ac network and not on ethernet (usually connected via 802.11n until people upgrade to newer machines), but most of the time people are connected to our thunderbolt displays which have a gigabit ethernet connection on them. Our network topology is one 32 port gigabit switch with 5 smaller gigabit switches at each desk cluster. The mac mini server is connected directly to the top level switch. Update: Failing information from someone who has done this in practice, I suppose my question is really around how switches work. If three or four people are backing up simultaneously, and then other two (different) users transfer a file between each other, will they be able to transfer the file at gigabit speeds?

  • Change the User Interface Language in Ubuntu

    - by Matthew Guay
    Would you like to use your Ubuntu computer in another language?  Here’s how you can easily change your interface language in Ubuntu. Ubuntu’s default install only includes a couple languages, but it makes it easy to find and add a new interface language to your computer.  To get started, open the System menu, select Administration, and then click Language Support. Ubuntu may ask if you want to update or add components to your current default language when you first open the dialog.  Click Install to go ahead and install the additional components, or you can click Remind Me Later to wait as these will be installed automatically when you add a new language. Now we’re ready to find and add an interface language to Ubuntu.  Click Install / Remove Languages to add the language you want. Find the language you want in the list, and click the check box to install it.  Ubuntu will show you all the components it will install for the language; this often includes spellchecking files for OpenOffice as well.  Once you’ve made your selection, click Apply Changes to install your new language.  Make sure you’re connected to the internet, as Ubuntu will have to download the additional components you’ve selected. Enter your system password when prompted, and then Ubuntu will download the needed languages files and install them.   Back in the main Language & Text dialog, we’re now ready to set our new language as default.  Find your new language in the list, and then click and drag it to the top of the list. Notice that Thai is the first language listed, and English is the second.  This will make Thai the default language for menus and windows in this account.  The tooltip reminds us that this setting does not effect system settings like currency or date formats. To change these, select the Text Tab and pick your new language from the drop-down menu.  You can preview the changes in the bottom Example box. The changes we just made will only affect this user account; the login screen and startup will not be affected.  If you wish to change the language in the startup and login screens also, click Apply System-Wide in both dialogs.  Other user accounts will still retain their original language settings; if you wish to change them, you must do it from those accounts. Once you have your new language settings all set, you’ll need to log out of your account and log back in to see your new interface language.  When you re-login, Ubuntu may ask you if you want to update your user folders’ names to your new language.  For example, here Ubuntu is asking if we want to change our folders to their Thai equivalents.  If you wish to do so, click Update or its equivalents in your language. Now your interface will be almost completely translated into your new language.  As you can see here, applications with generic names are translated to Thai but ones with specific names like Shutter keep their original name. Even the help dialogs are translated, which makes it easy for users around to world to get started with Ubuntu.  Once again, you may notice some things that are still in English, but almost everything is translated. Adding a new interface language doesn’t add the new language to your keyboard, so you’ll still need to set that up.  Check out our article on adding languages to your keyboard to get this setup. If you wish to revert to your original language or switch to another new language, simply repeat the above steps, this time dragging your original or new language to the top instead of the one you chose previously. Conclusion Ubuntu has a large number of supported interface languages to make it user-friendly to people around the globe.  And since you can set the language for each user account, it’s easy for multi-lingual individuals to share the same computer. Or, if you’re using Windows, check out our article on how you can Change the User Interface Language in Vista or Windows 7, too!

  • Diagnose PC Hardware Problems with an Ubuntu Live CD

    - by Trevor Bekolay
    So your PC randomly shuts down or gives you the blue screen of death, but you can’t figure out what’s wrong. The problem could be bad memory or hardware related, and thankfully the Ubuntu Live CD has some tools to help you figure it out. Test your RAM with memtest86+ RAM problems are difficult to diagnose—they can range from annoying program crashes, or crippling reboot loops. Even if you’re not having problems, when you install new RAM it’s a good idea to thoroughly test it. The Ubuntu Live CD includes a tool called Memtest86+ that will do just that—test your computer’s RAM! Unlike many of the Live CD tools that we’ve looked at so far, Memtest86+ has to be run outside of a graphical Ubuntu session. Fortunately, it only takes a few keystrokes. Note: If you used UNetbootin to create an Ubuntu flash drive, then memtest86+ will not be available. We recommend using the Universal USB Installer from Pendrivelinux instead (persistence is possible with Universal USB Installer, but not mandatory). Boot up your computer with a Ubuntu Live CD or USB drive. You will be greeted with this screen: Use the down arrow key to select the Test memory option and hit Enter. Memtest86+ will immediately start testing your RAM. If you suspect that a certain part of memory is the problem, you can select certain portions of memory by pressing “c” and changing that option. You can also select specific tests to run. However, the default settings of Memtest86+ will exhaustively test your memory, so we recommend leaving the settings alone. Memtest86+ will run a variety of tests that can take some time to complete, so start it running before you go to bed to give it adequate time. Test your CPU with cpuburn Random shutdowns – especially when doing computationally intensive tasks – can be a sign of a faulty CPU, power supply, or cooling system. A utility called cpuburn can help you determine if one of these pieces of hardware is the problem. Note: cpuburn is designed to stress test your computer – it will run it fast and cause the CPU to heat up, which may exacerbate small problems that otherwise would be minor. It is a powerful diagnostic tool, but should be used with caution. Boot up your computer with a Ubuntu Live CD or USB drive, and choose to run Ubuntu from the CD or USB drive. When the desktop environment loads up, open the Synaptic Package Manager by clicking on the System menu in the top-left of the screen, then selecting Administration, and then Synaptic Package Manager. Cpuburn is in the universe repository. To enable the universe repository, click on Settings in the menu at the top, and then Repositories. Add a checkmark in the box labeled “Community-maintained Open Source software (universe)”. Click close. In the main Synaptic window, click the Reload button. After the package list has reloaded and the search index has been rebuilt, enter “cpuburn” in the Quick search text box. Click the checkbox in the left column, and select Mark for Installation. Click the Apply button near the top of the window. As cpuburn installs, it will caution you about the possible dangers of its use. Assuming you wish to take the risk (and if your computer is randomly restarting constantly, it’s probably worth it), open a terminal window by clicking on the Applications menu in the top-left of the screen and then selection Applications > Terminal. Cpuburn includes a number of tools to test different types of CPUs. If your CPU is more than six years old, see the full list; for modern AMD CPUs, use the terminal command burnK7 and for modern Intel processors, use the terminal command burnP6 Our processor is an Intel, so we ran burnP6. Once it started up, it immediately pushed the CPU up to 99.7% total usage, according to the Linux utility “top”.
