  • Launching an application from Bash

    - by JBoy
    I'm right now busy with moving the first steps into Linux, i'm using a bash shell within a mac osx I see in all tutorials that in order to launch an application from the bash its necessary to cd to its directory and simply type the name of the app. This is exatly what i'm doing and it does not work (i have on my desktop a 'Eclipse' folder with the launcher icon in it): cd Desktop cd Eclipse Eclipse.app Why will this not work? I read everywhere that typing the name of the app its enough

  • How force text-only pasting in emacs?

    - by eaubin
    On my mac I always have an emacs buffer open and occasionally I have to copy content from PowerPoint or Word. Unfortunately, copying to the clipboard and yanking into emacs saves all the ugly formatting (and graphics) from the original document. I only want to paste in the text (and never the formatting). My current solution is to paste into TextWrangler and then repaste into emacs. What's a better way to do this?

  • virtualisation with kvm: export services from guest to the host

    - by ascobol
    Hello, I would like to export some services from the guest os to the host os, via kvm, and by the same way learn some things about networking. I have tried the following commands: In the host (kubuntu 10.4): $ sudo tunctl -u ascobol Set 'tap0' persistent and owned by uid 2401 $ sudo ifconfig tap0 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255 The ifconfig command returns: $ /sbin/ifconfig tap0 Link encap:Ethernet HWaddr 3e:4e:e3:cc:bc:92 inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::3c4e:e3ff:fecc:bc92/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:17 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 Then I run the virtual machine (ubuntu server 10.4): $ sudo kvm -hda ubuntuserver104.qcow2 -net nic -net tap,name=tap0,script=no (I'm using sudo because without it fails with the following message:) warning: could not configure /dev/net/tun: no virtual network emulation With sudo the virtual machine boots, I just get this message: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin" In the virtual machine: $ ifconfig eth0 192.168.2.2 netmask 255.255.255.0 broadcast 192.168.2.255 Now if I run: $ ssh 192.168.2.2 I just get a No route to host What is wrong with this setup ?

  • Strange windows boot problem - My computer won't boot from hard disk

    - by user29779
    Hello, Until yesterday, I had windows XP installed on my computer. After installing the OS, and setting the BIOS to boot from the hard-disk first, I discovered a strange problem - the OS wasn't booted and the only way I could get it to load was to insert a windows installation disk, enter repair mode, do "fixboot" and restart. The problem only occured when the computer was booted after shut-down. If I only restarted it, everything worked fine. Yesterday, I upgraded my XP to win7 and the problem persists. I tried the same "trick" I did with XP to get it to load, by entering repair and doing "bootrec /fixmbr" and "bootrec /fixboot" but that didn't work (and when I run "scanos" it didn't find any windows installations). Eventually, I got it to load by changing the settings in the BIOS to boot from CD first and HD second, removing the installation disk from the drive, letting it fail to boot from CD and then re-insert the disk. Anyone has any idea what may be the cause or how can I investigate this issue? Thanks! Marina

  • Referencing groups/classes from Puppet dashboard in my site manifest

    - by Banjer
    I'm using Puppet Dashboard as my ENC and I'm not sure how to reference or use class and group classifications from /etc/puppet/manifests/site.pp. I have two groups defined in the dashboard: CentOS6 and SLES11. What should my site.pp look like if I want to include a certain list of modules in the CentOS6 group and a certain list of modules in the SLES11 group? I'm trying to do something like this: # /etc/puppet/manifests/site.pp node basenode { include hosts include ssh::server include ssh::client include authentication include sudo include syslog include mail } node 'CentOS6' inherits basenode { include profile } node 'SLES11' inherits basenode { include usrmounts } I have OS-specific case statements within my modules, but there are some modules that will only be applied to a certain distro. So I suppose I have two questions: Is this the best way to apply modules/resources in an OS-specific manner? Or does the above make you want to vomit? Regardless of #1, I'm still curious as how to reference classes, groups, and nodes from Dashboard within my manifests. I've read the External Nodes doc, but I'm not seeing how they correspond to manifests. Thanks all.

  • Unix: softlinks, hardlinks

    - by sixtyfootersdude
    I am somewhat confused what the differences between a softlink, and a hardlink are (on unix). It seems like a softlink is the same as a shortcut in windows or an alias on Mac OS X. (Can someone confirm this?) Softlinks can link to both directories and files. I am uncertain of what a hardlink does or if it is useful.. Is it better to use one instead of the other? Thanks.

  • SSD with multiple partitions - disk life implications

    - by Nicolas Webb
    Each block on a SSD has a finite number of writes. This is mitigated on modern drives by "spreading" the writes around as you use the drive. I'm wondering if you partition a SSD into several partitions (a Mac using Boot Camp, for example) if this measure is defeated somewhat - can the writes be spread across the entire drive? Or are they contained strictly within the partition boundaries? Any SSD controller engineers here :)?

  • Windows 7 64-bit installation from alternative media (no DVD/USB Flash drive)

    - by Niels Willems
    Greetings I currently have Windows 7 x86 installed on my computer. I want to install Windows 7 x64 on a different partition on my computer. However there is a little issue, I cannot run the x64 install from Windows 7 x86 which I currently have. I was planning to Install Windows 7 x64 on another partition to then boot up from that partition to install it on the partition I actually want my OS on. Once that is complete I could just format the partition from the Windows 7 x64 that I didn't need anymore. But the installer will not run from the x86 version of Windows 7 even though I do not want to upgrade that Windows directly. The reason I'm doing this in such a weird way is that my optical drive is broken and I'm really not into buying a new one since I would use it like once every year or so. I also don't have a USB Flash Drive which is big enough to hold the installation files. As far as I'm aware I cannot use an external hard drive such as this one, which I do have. Are there any alternatives in which I can install Windows 7 x64 or am I forced into buying a USB Flash Drive or new optical drive? Thank you in advance for your replies. Edit: This picture shows my current partitions on my laptop. I want to get Windows 7 x64 on the C partition but have to install it first on the F partition to then boot up the F partition windows to format C and install x64 on that one. My external drive is J. Edit 2: No alternative computer which has a DVD drive, install files are located on an iso from MA3D. To install my 32 bit version I mounted the ISO in Daemon Tools to replace my Windows Vista but since I cannot run 64 bit into my 32 bit OS this doesn't work.

  • Media file segmenter like tool for linux

    - by Raja
    Hello everyone I'm looking for a tool for linux which can segment a video file into multiple small .ts files. I know one for Mac OS X called media file segmenter which is a simple command line tool. I really appreciate if anyone can point me to an equivalent linux tool. I don't know if these types of non-programming questions are allowed on this site. my apologies for that.

  • MySQL not releasing temp file descriptors

    - by Wakaru44
    Since a few days ago, we’ve been experiencing some serious problems with our MySQL installation: MySQL keeps opening temporal files (normal behaviour) but these files are never released. The consequence is that, eventually, the disk space is exhausted and we have to restart the service and clean up /tmp manually. Using lsof, we see something like this: mysqld 16866 mysql 5u REG 8,3 0 692 /tmp/ibyWJylQ (deleted) mysqld 16866 mysql 6u REG 8,3 0 707 /tmp/ibf5adsT (deleted) mysqld 16866 mysql 7u REG 8,3 0 728 /tmp/ibGjPRyW (deleted) mysqld 16866 mysql 8u REG 8,3 0 5678 /tmp/ibMQDLMZ (deleted) mysqld 16866 mysql 13u REG 8,3 0 5679 /tmp/ibQAnM42 (deleted) Maybe it's not related, but when we shutdown the server, the files are finally freed, and we can see the following warnings in the MySQL log: 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1333 user: 'xxx' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1156 user: 'yyy' 121029 7:44:27 [Warning] /usr/local/mysql/bin/mysqld: Forcing close of thread 1151 user: 'zzz' where 'xxx', 'yyy' and 'zzz' are distinct mysql users (and the only 3 users with active connections to the database). We have a few theories: There is a problem in the OS, that keeps file handlers open. Could it be possible that the OS "delete" operation blocks the threads until shutdown? This may explain the warning at shutdown and the fact that files are finally deleted when the process dies. Until now, data sets were so small that temp files were relatively small and there was enough time to release the file handles without exhausting disk space. We are using Mysql 5.5 on a RHEL 6.2 with the default kernel.

  • Consolidated queue for video on demand?

    - by Herb Caudill
    It's great having lots of video on demand options, but actually choosing something to watch is turning into a mess - I have to jump from one website or application to another. I'd like to have a single queue where I can add and prioritize movies and TV I want to watch from any source: iTunes purchases, iTunes rentals, Netflix on demand, Amazon video on demand, Hulu, etc. I'd like the consolidated queue to be accessible from Front Row on my Mac Mini. Does such a thing exist?

  • How do I combine static and dynamic DHCP leases on a Cisco router?

    - by Brad
    Basically, what I need is super similar to the unanswered cisco forum question below: https://supportforums.cisco.com/message/3139749#3139749 I have a Cisco 850 Series router. I have configured a DHCP pool for the 10.0.0.0/24 network. I have excluded 10.0.0.1 - 10.0.0.99 from the DHCP pool. I want to add a static DHCP pool for stuff and I want DHCP to statically assign them the addresses of my choice below 100. Actually, I don't care what addresses I statically assign. They can be anything in the pool for all I care, I just want it to work. Why are you doing this? Just statically assign the IPs on the devices! I don't want to do this because I have some laptop users. They could obviously only use that static IP here. This isn't a problem if they could be bothered to change any location setting or something. They can't. So it HAS to be DHCP. It also has to be static IPs because I need to forward ports to them. I know, I know, this is weird but it's an apartment LAN/WLAN so this isn't exactly a typical use case. Relevant sections of config below: ip dhcp excluded-address 10.0.0.1 10.0.0.99 ! ip dhcp pool Internal-net import all network 10.0.0.0 255.255.255.0 default-router 10.0.0.1 domain-name 1770.local lease 7 ! ip dhcp pool static-pool import all origin file flash://staticmap default-router 10.0.0.1 domain-name 1770.local Contents of staticmap: *time* Aug 5 2010 09:00 AM *version* 2 !IP address Type Hardware address Lease expiration 10.0.0.100/24 1 001f.5b3e.d50a Infinite *end* You can see here I was trying addresses outside the excluded-address range to see if that would make any difference. My testing machine's MAC: mainframe:~ brad$ ifconfig en1 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:1f:5b:3e:d5:0a What shows up in the DHCP binding table: basestar#show ip dhcp binding Bindings from all pools not associated with VRF: IP address Client-ID/ Lease expiration Type Hardware address/ User name 10.0.0.112 0100.1f5b.3ed5.0a Aug 12 2010 10:06 AM Automatic What's up with the funny looking MAC in the DHCP binding table?? Is what I'm trying to accomplish basically impossible? Am I going about this the wrong way? All I want to to be able to port forward some ports to specific devices. The way I would do this with a consumer router is to do what I'm trying to do here; assign static DHCP to those devices then configure PAT for ports on those addresses.

  • Installing the Newest KeePass for MacOSX from Source

    - by firebush
    I've transitioned our passwords to KeePass. LastPass looks cool, but I prefer a system where we control the database locally rather than it being kept in the cloud. I have a windows and Linux system and both are able to access our KeePass database easily. On my Linux system (Ubuntu), I simply installed KeePass via synaptic and it just worked. So everything was working great, until my wife tried to set up things on her MacBook to access the database. Huge problems. It was so easy on Linux that I didn't expect there to be issues there. In case it's helpful, she's running a fresh install of Mac OSX 10.5.8, Leopard. We simply went to the download site for KeePass: http://keepass.info/download.html Clicked on the link titled KeePass 2.x for Mac OS X from which we retrieved Mono 2.10.5 and KeePass 2.18 from that site (the packages posted there at the time of this writing). Mono installed without problems (at least, none that we saw). She opened the KeePass image and dragged it to the Application side, unpackaging it there. According to the instructions on the KeePass installation instructions, she opened a terminal, changed to the directory in /Applications containing KeePass.exe, and ran it through mono: mono KeePass.exe No application opens at all - we see a blip for it, but then it immediately goes away, indicating to us that it is crashing. Also disconcerting, I see that people are throwing fits about copy-and-paste not working for KeePass 2.18 on MacOSX. Judging from the 2.19 addresses the copy/paste issue. I'm hoping that version will solve all our issues. So here's my question: how can I try out 2.19 on her system. It doesn't seem to be packaged like the 2.18 one is. But we're not scared of building it. I see that the source for 2.19 is here (at the bottom of the page). Can I just download that to her machine somewhere and run something to build it? I'm familiar with automake but not with building .NET source, so please answer gently if this is stupidly easy. :^) btw: tomorrow's my wife's birthday, and this is getting her down. If you know how to navigate these issues, it would be a nice birthday gift for her. Thanks in advance! Update I'll post this since it might be helpful to someone else: I got KeePass 2.18 to run by updating Mono to 2.10.9 (rather than the 2.10.5 given by the site above). With the later version of Mono, it runs without crashing. And yet, I do see the copy and paste issue that others see. I can open a database on her machine, but the incorrect data get's copied. So again, can someone help me install KeePass 2.19? Thanks!

  • How do I securely delete cookies and saved passwords?

    Is there a way, from inside the browser, to delete cookies and saved passwords in such a way that the data is unrecoverable (similar to Secure Empty Trash)? I know I can probably track down all the files involved and then manually do this, but I'm curious if there's an easier way. Or maybe browsers already do it out of the box? I'm specifically looking for solutions for Firefox and Safari, on Mac OS X.
