  • Running a command in a new Mac OS X Terminal window.

    - by Walt D
    Hi, I've been trying to figure out how to run a bash command in a new Max OS X Terminal.app window. As, an example, here's how I would run my command in a new bash process: bash -c "my command here" But this reuses the existing terminal window instead of creating a new one. I want something like: Terminal.app -c "my command here" But of course this doesn't work. I am aware of the "open -a Terminal.app" command, but I don't see how to forward arguments to the terminal, or even if I did what arguments to use. Thanks!

  • Mixing libraries with and without RTTI with GCC on Mac OS X?

    - by Steve the Plant
    I've been banging my head on an issue and before I continue injuring myself some more, I'd like to confirm: Is it possible to have a GCC project that uses libraries that are compiled with and without RTTI? So, for example, I have project A (compiled without RTTI) that uses library B (compiled with RTTI) and library C (compiled without RTTI). In theory, is all that supposed to compile and link with no problems?

  • Mac OSX: Passing a link to file from user process to kernel module.

    - by Inso Reiges
    Hello, I need to pass a link to file from a user process to the OSX kernel driver. By link i mean anything that uniquely identifies a file on the local filesystem. I need that link to do I/O on that file in kernel. The most obvious solution seems to pass a file name and use a VFS vnode lookup. However i noticed, that Apple Disk Images helper process passes a raw data array for image-path property to driver when attaching a disk image file: <2f 56 6f 6c 75 6d 65 73 2f 73 74 6f 72 61 67 65 2f 74 65 73 74 32 2e 64 6d 67> What is that diskimages-helper passes to the kernel driver? Some serialized type perhaps? If yes, what type is it and how can i use it?

  • How can I terminate a multicast stream (asr - Mac) in a script?

    - by user355896
    Hello, I'm making a script to to run a bunch of multicast asr streams, but I do not know how to "stop" or "end" a multicast asr stream after a certain amount of time. Loop Suspend does not do what I'm looking for. I've also tried to add a sleep command followed by a kill command, but they kick in after the stream ends (so that approach does not work). Thanks for any possible help! By the way, I'm writing this script in bash.

  • Mac OS X 10.5 App "not supported on this architecture" cured by copying?

    - by JWWalker
    I have an app that updates itself over the internet, and the updated copy won't run on PowerPC machines (G5) running Leopard (10.5.8). Double-clicking the app produces a message saying "You can't open the application "appname" because it is not supported on this architecture." But here's the weird part: if I duplicate the app using the Finder or using a cp -R command, then the duplicate runs fine! And yet, if I do ls -laeR on both apps, the results are identical. I restarted the machine, and the difference between the two copies was still there. Sometimes, renaming the app made it run. After a few tries, I managed to rename it back to the original name and still have it run. If this was just on one machine, I'd dismiss it as disk corruption, cosmic rays, or a voodoo hex, but it was reported by a customer and then I reproduced it on my own machine. Any ideas what could cause this behavior?

  • Best free alternative to Versions SVN on Mac OS X ?

    - by Nick
    Hi guys, Setting up some web development stuff with a friend, he's using Versions SVN (paid for by his company) which looks fantastic but is a touch pricey. I was tempted by SVNx but if I'm honest don't like the idea of using command line at all - much prefer a nice and easy to use GUI. I don't mind paying for it if I have to, but I was wondering if there were any really good alternatives? We'll be using Springloops as an SVN fwiw. Thanks

  • Ubuntu Server running VNC

    - by xwapilot
    I have access to four computers: 1 Ubuntu Server desktop (Version 10.04) 1 Mac Mini (Snow Leopard) 1 Windows desktop (Windows 7) 1 Windows laptop (Windows Vista) The first three will always be on the home network. My goal is to SSH from the laptop into the server and be able, through VNC (or another remote desktop software), to control the windows and mac computers. The goal of this would be a slightly heightened network security over using VNC to directly access the mac or windows desktop. I have successfully used SSH to connect to the server, but have not been able to successfully implement the remote desktop connection. I would appreciate help doing so. Here's what I've done so far: As per instructions here: http://www.stuartellis.eu/articles/vnc-on-linux/ I installed the following: vnc4server – the main VNC server software vnc-java – enables access from Web browsers with Java support xvnc4viewer – a basic VNC viewer I then set up a password using the vncpasswd command. To attempt to connect to the mac, I followed directions I found in a thread at superuser. com and went to "System PreferencesSharing" and enabled "Screen Sharing". Subsequently, I tried entering the following commands into Ubuntu: vncviewer mac_ip_address::5904 vncviewer mac_ip_address:0 vncviewer mac_ip_address:1 They all returned the following: VNC Viewer Free Edition 4.1.1 for X - built Apr 9 2010 18:41:55 Copyright (C) 2002-2005 RealVNC Ltd. See http ://www .realvnc. com for information on VNC. vncviewer: unable to open display "" I'm sure I'm missing something important, but I'm not sure what it is. Do I need to have a GUI installed, or did that come with the vnc packages I installed?

  • Do I need to match hardware on a Mac to my PC to get the same user experience?

    - by Darth
    I've been playing around with the thought of moving from a PC to a Mac. if you don't want to read this, skip to the "upgrade options" My current setup Most of my time I spent moving back and forth between Linux and Windows. During the last upgrade to Vista, I got myself pc with Core 2 Quad, 8GB of RAM and GeForce 9800GTX+. Currently I'm running dual boot between Ubuntu 10.04 and Windows Vista x64. Most of my work, around 80%, I can do on Ubuntu, which is mostly Ruby/Java programming. If that was all I needed, Ubuntu would be really great. However, I also do quite a lot of Photography and Design, which forces me to use Adobe software (not only Photoshop). I also work with Wacom Intuos4 tablet, which doesn't really have great support on Linux machines. I've tried virtualization both ways (Linux in Win and Win in Linux), but neither was anywhere near satisfying. These are those of many many reasons I want to move to OS X. Upgrade options This is how I see my upgrade options: Mac Mini - cheapest solution, but worst performance iMac - more expensive, better performing with second LCD for free Mac Pro - could match my current PC performance, currently outside of the price range When I compare the Mac hardware vs my current PC, it will be always worse, unless I decide to pump in a lot of money. The question that comes to my head, do I need to match my current PC hardware to get the same user experience with a Mac? If I look at it from the Vista point of view, 2GB RAM is as low as it gets, 4GB is usable ... and the 8GB runs very smoothly. PC HW != Mac HW? If I bought the Mac Mini for roughly the same price I paid for my PC (Core 2 Quad with 8GB RAM), I'd get Core 2 Duo with 4GB RAM. But I don't want to run Vista on it, so I can't compare the hardware directly. Say that I want to do the same things on the Mac Mini as I do on my PC, eg. open up 50 tabs in Google Chrome and start working with a large PSD in Photoshop (couple hundred MB), would running on Mac OS X compensate for the lower hardware performance? My point is, that if I'm about to upgrade, I wouldn't like to upgrade to hardware that runs a lot slower. Good analogy for this is Vista vs Ubuntu, where you can run Ubuntu smoothly on a low end laptop, but in Vista, you'd be happy to open a browser. Does the same principle apply to OS X?

  • Get Python to raise MemoryError instead of eating all my disk space

    - by asmeurer
    If I run a Python program with a memory leak, I would normally expect the program to eventually die with MemoryError. But instead, what happens is that all the virtual memory is used until my disk runs out of space. I am running Mac OS X 10.8 on a retina MacBook Pro. My computer generally has between 10GB to 20GB free. Mac OS X is smart enough to not die completely when the disk runs out of space (rather, it gives me a dialog letting me force quit my GUI programs). Is there a way to make Python just die when it runs out of real memory, or some reasonable amount of virtual memory? This is what happens on Linux, as far as I can tell. I guess Mac OS X is more generous than Linux with virtual memory (the fact that I have an SSD might be part of this; I don't know just how smart OS X is with this stuff). Maybe there's a way to tell the Mac OS X kernel to never use so much virtual memory that leaves less than, say, 5 GB free on the hard drive?

  • Enable FTP on OS X 10.8 Mountain Lion Server

    - by Oleg Trakhman
    There is a LAN comprising several mac machines (iMac, Mac Pro, macbook etc.), Airport Express router and Mac Mini Server running OS X Server 10.8 (Mountain Lion Server). I need to share a folder on Mac Mini Server by FTP. What did I try so far: Made special partition for FTP Access, call it "Reports" So shared folder would be "/Volumes/Reports" Gave access every user and group in system, and also enabled guest access. I checked posix acl, which is "rwxrwxrwx", I checked sharing settings in "Preferences.app" and "Server.app" Checked that users have access to FTP service Enabled FTP in Server.app I tried access to shared folder (by FTP): via Cyberduck via Finder via shell: ftp server.local And what I got: $ ftp [email protected] Trying 10.0.2.2... Connected to server.local. 220 10.0.2.2 FTP server (tnftpd 20100324+GSSAPI) ready. 331 User ftpuser accepted, provide password. Password: 530 User ftpuser may not use FTP. and $ ftp [email protected] Trying 10.0.2.2... Connected to server.local. 220 10.0.2.2 FTP server (tnftpd 20100324+GSSAPI) ready. 331 User admin accepted, provide password. Password: 530 User admin denied by SACL. ftp: Login failed ftp> (admin is administrator account , ftpuser is special user account made to access ftp) What I'm doing wrong? Getting really tired of this...

  • Discover the public ip of a network without being connected

    - by Martin Trigaux
    Let say, I'm next to a network and can see the traffic (with airodump or similar tool) but can not decipher it (because I am not connected on the network). Is it possible to discover the public ip address of the network ? I know the MAC address of the users connected on the network but do I know the one of the router ? If yes, maybe there is a way to do the matching. I know IP addresses are not forever but some addresses are static and never change. Maybe there is a database of MAC address having recorded that. Google has a database that match MAC address and geographical coordinates so why not with IP addresses ? Other idea, if I know where am I, I can maybe guess the IP range used in the city by the ISP (is it findable ?) and then try to "ping" each IP on the range (if it is a /24, it's possible, even /16 maybe). Will I get some information like the MAC of the box or see some traffic on the network ? These are two ideas I had. I don't know if they are doable, certainly not perfect. Do you think of some others ? By trying several methods, maybe I can get a guess with a bit of luck. Thank you

  • Where is sdl-config installed on MacOS 10.6 (Snow Leopard)

    - by jmglov
    After installing SDL and SDL-devel in MacOS X 10.6 (Snow Leopard), trying to configure some source code that requires SDL yields: checking for sdl-config... no checking for SDL - version >= 1.2.0... no *** The sdl-config script installed by SDL could not be found *** If SDL was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the SDL_CONFIG environment variable to the *** full path to sdl-config. configure: error: *** SDL version 1.2.0 not found! Does anyone know where to find sdl-config? I guess I can build SDL from source, but why should I have to, when there exist pre-built packages?

  • iphone OS 3.1.3 requires snow leopard upgrade

    - by unsorted
    itunes asked me to upgrade my iphone's OS to 3.1.3, so I complied naively. then xcode told me that the latest iphone OS version it could support was 3.1.2. So I went to download a new version from https://developer.apple.com/iphone/index.action#downloads, xcode 3.2.2 with iphone SDK. but when i went to install that, i was told I needed snow leopard 10.6.2 or later. so I'm just making sure that I am not misinterpreting anything when I say that, given that it is impossible to downgrade iphone OS versions without jailbreaking, I need to install a new version of the OS just so I can resume testing apps on my iphone?

  • Configuring VirtualBox host only networking: OSX host, Ubuntu guest

    - by Greg K
    I have a Ubuntu guest configured with two interfaces, eth0 is using NAT and works fine, I can access the net. The second interface eth1 is set to host only networking and VirtualBox has created a vboxnet0 virtual adapter on the host. I've configured vboxnet0 in VirtualBox adapter settings with the following: ip 192.168.21.20 subnet 255.255.255.0 Once the VM guest is running, ifconfig on OSX has vboxnet0 setup as: vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:00 inet 192.168.21.20 netmask 0xffffff00 broadcast 192.168.21.255 In the guest, eth0 is set to use DHCP, I've statically assigned eth1 to 192.168.21.20 (is this a mistake?): auto eth1 iface eth1 inet static address 192.168.21.20 netmask 255.255.255.0 network 192.168.21.0 broadcast 192.168.21.255 gateway 192.168.21.1 There is no device on 192.168.21.1 - what should I set my gateway to?

  • 4GB of RAM in MacOSX 10.5, only 3GB in MacOSX 10.6

    - by Albert
    Hi, I was using MacOSX 10.5 on my MacBook until today and I had 4GB of memory there. Now I have updated to MacOSX 10.6 and it only displays 3GB. Why is that? How can I fix it? Also, I am a bit wondering why most people (well, most of the Google hits explained the 3GB issue that way -- leaving out the fact that it has worked earlier) are saying that a 32bit system can under no circumstances access more than 3.2GB. Don't we have PAE nowadays in most systems? Thanks, Albert

  • Shared secret length limit on OSX VPN client

    - by Samuel
    I'm trying to setup the built-in VPN client with OS X. The settings I'm using (IPsec GW, shared secret, etc...) work flawlessly using other clients (IPsecuritas, vpnc, etc...) but isn't working with the built-in client. The error I get is: Wrong shared secret (not the exact message, since OS X is localized) The shared secret is 128 chars long so I'm wondering if it's hitting a length limit. I would like to know if that's true, and if so, how I could overcome it?
