  • run or send a command to a tmux pane in a running tmux session

    - by cjroebuck
    I want to write a shell script which will attach to a named tmux session, select a window (or pane) in that session and run a command in that selected window (or pane). How do I do this from a bash script? I know tmux new-window -n:mywindow 'exec something' allows you to send commands to a freshly created window. But I need something like tmux select-window -t:0 'my command' I suppose I could use send-keys but seems like their should be something that takes a command or list of commands that get run.

  • Create Hidden Partition on USB

    - by Francesco
    I need to split an USB flash disk into two USB drives, each one with its own drive letter, but one of these has to be hidden. In the non-hidden partition I want to place my software, and in the hidden partition I need to place some files that are required by the software in order to work. Moreover, only the software may read, write, delete or execute the files in this partition. I thought to use a little partition viewed as a CD-ROM drive, as they do in many flash drives, but this solution does not allow to write other data in a second moment, and it's visible to the user that can read the file. Obviously the software must be able to access to partition and read, write, delete or execute the content. Is there a solution to do so, possibly that work also on Linux?

  • Problem importing pictures from a digital camera with Windows 7

    - by snark
    Hi, Since I'm using Windows 7 (Beta, then RC, now RTM), I have issues when I download pictures from my digital cameras. It happens with my 2 cameras: a Canon Powershot S2 IS and a Canon Ixus 80 IS. When I plug a camera (any of them) to a USB port and switch it on in Play mode, the Autoplay function of Windows 7 starts with this screen: I select "Import pictures and videos" to call the native Windows 7 tool. It searches a bit for pictures to download from the camera and starts the transfer. However, during the transfer, I often get errors like this one: If I use "Try again", it works fine the second time and the picture is retrieved correctly. It's very annoying when it happens 20 or 30 times in a 500-picture download. I cannot leave it running standalone, as I have to watch for the errors and click on "Try again". Any idea what is causing these errors? I tried changing the USB port (normally the cameras are connected via a USB hub but it happens also when I connect them directly to a MB USB port) and the USB cable, but no success. I also checked the SD card by connecting them with a card reader and running a ChkDsk on them but it found no errors on the cards. Update: No problem when I copy the pictures manually with the Windows Explorer. And no problem either when I access the card with a reader. The builtin import tool of Windows is convenient as it sorts the pictures automatically by date (1 folder per day). And this is the way I sort my pictures

  • Can Mac KeyNote presentations exported for Windows be shown in good quality and be edited?

    - by Edward Tanguay
    A friend asked me this: ...I stopped using KeyNote for one simple reason – contrary to the Mac marketing blurb, the final presentations do NOT work fine on Windows PCs – they look distorted and have formatting quirks which cannot be corrected because the Windows/Powerpoint file it has supposedly been saved as is in fact a non-editable file, kind of like a pdf. Is there a way to create Mac KeyNote presentation files so they look nice on Windows and can be edited?

  • Opera 10.5 RAM usage and Google Reader?

    - by David
    Hi all, Today I upgraded to Opera 10.5 from Google Chrome and I have two really important questions about it. 1) Is it normal for it to use SO MUCH RAM!!!!? Closing tabs doesn't help, but opening new ones add on to the usage. I can have just 4 tabs open and it goes up to the 300MB mark and I only have 1.5GB in my laptop, 596MB of it used by the graphics card so this really unacceptable. Is there a way to fix it? 2) Why does Google Reader feel so slow and unresponsive on it? It lags so bad when I just try scrolling through the page. I know Opera is known for being really smooth while scrolling through pages. There's also a white bar at the bottom of the page that I can get rid of. It blocks the "Next" and "Previous" buttons. The test between articles is also sort of intersecting each other and that just looks completely unattractive and that's something i'm not used with any web browser. I realize there's a built-in RSS reader, but it doesn't sync across multiple computers and is very late at updating. Here are my specs: Windows 7 Ultimate (x86), Intel Pentium M 1.86 GHz, 1.5GB RAM, ATI Mobility Radeon X600 (64MB dedicated, 596MB shared)

  • Root directory permissions on Mac OS X 10.6?

    - by Agos
    Hi, I was wondering if it's normal that the root directory / should be owned by “root”. I get asked for my password every time I want to do something there (e.g. save a file, create a directory) and I don't remember this happening before (though this may just be my faulty memory). Here's the relevant terminal output: MacBook:~ ago$ ls -lah / total 37311 drwxr-xr-x@ 35 root staff 1,2K 22 Mar 12:34 . drwxr-xr-x@ 35 root staff 1,2K 22 Mar 12:34 .. -rw-rw-r--@ 1 root admin 21K 22 Mar 10:21 .DS_Store drwx------ 3 root admin 102B 28 Feb 2008 .Spotlight-V100 d-wx-wx-wt 2 root admin 68B 31 Ago 2009 .Trashes -rw-r--r--@ 1 ago 501 45K 23 Gen 2008 .VolumeIcon.icns srwxrwxrwx 1 root staff 0B 22 Mar 12:34 .dbfseventsd ---------- 1 root admin 0B 23 Giu 2009 .file drwx------ 27 root admin 918B 22 Mar 10:55 .fseventsd -rw-r--r--@ 1 ago admin 59B 30 Ott 2007 .hidden -rw------- 1 root wheel 320K 30 Nov 11:42 .hotfiles.btree drwxr-xr-x@ 2 root wheel 68B 18 Mag 2009 .vol drwxrwxr-x+ 276 root admin 9,2K 19 Mar 18:28 Applications drwxrwxr-x@ 21 root admin 714B 14 Nov 12:01 Developer drwxrwxr-t+ 74 root admin 2,5K 18 Dic 22:14 Library drwxr-xr-x@ 2 root wheel 68B 23 Giu 2009 Network drwxr-xr-x 4 root wheel 136B 13 Nov 17:49 System drwxr-xr-x 6 root admin 204B 31 Ago 2009 Users drwxrwxrwt@ 4 root admin 136B 22 Mar 12:35 Volumes drwxr-xr-x@ 39 root wheel 1,3K 13 Nov 17:44 bin drwxrwxr-t@ 2 root admin 68B 23 Giu 2009 cores dr-xr-xr-x 3 root wheel 5,1K 17 Mar 11:29 dev lrwxr-xr-x@ 1 root wheel 11B 31 Ago 2009 etc -> private/etc dr-xr-xr-x 2 root wheel 1B 17 Mar 11:30 home drwxrwxrwt@ 3 root wheel 102B 31 Ago 2009 lost+found -rw-r--r--@ 1 root wheel 18M 3 Nov 19:40 mach_kernel dr-xr-xr-x 2 root wheel 1B 17 Mar 11:30 net drwxr-xr-x@ 3 root admin 102B 24 Nov 2007 opt drwxr-xr-x@ 6 root wheel 204B 31 Ago 2009 private drwxr-xr-x@ 64 root wheel 2,1K 13 Nov 17:44 sbin lrwxr-xr-x@ 1 root wheel 11B 31 Ago 2009 tmp -> private/tmp drwxr-xr-x@ 17 root wheel 578B 12 Set 2009 usr lrwxr-xr-x@ 1 root wheel 11B 31 Ago 2009 var -> private/var Are these ownerships / permissions ok?

  • Unable to connect to OpenVPN server

    - by Incognito
    I'm trying to get a working setup of OpenVPN on my VM and authenticate into it from a client. I'm not sure but it looks to me like it's socket related, as it's not set to LISTEN, and localhost seems wrong. I've never set up VPN before. # netstat -tulpn | grep vpn Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 127.0.0.1:1194 0.0.0.0:* 24059/openvpn I don't think this is set up correctly. Here's some detail into what I've done. I have a VPS from MediaTemple: These are my interfaces before starting openvpn: lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:39482 errors:0 dropped:0 overruns:0 frame:0 TX packets:39482 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3237452 (3.2 MB) TX bytes:3237452 (3.2 MB) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:4885284 errors:0 dropped:0 overruns:0 frame:0 TX packets:4679884 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:835278537 (835.2 MB) TX bytes:1989289617 (1.9 GB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:205.[redacted] P-t-P:205.186.148.82 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 I've followed this guide on setting up a basic server and getting a .p12 file, however, I was receiving an error that stated /dev/net/tun was missing, so I created it mkdir -p /dev/net mknod /dev/net/tun c 10 200 chmod 600 /dev/net/tun This resolved the error preventing the service from launching, however, I am unable to connect. On the server I've set up the myserver.conf file (as per the tutorial) to indicate local 127.0.0.1 (I've also attempted with the public IP address, perhaps I don't understand what they mean by local IP?).

On the client-side I've installed the p12 certs onto two devices (one is an android tablet, the other is an Ubuntu desktop). I don't see port 1194 as open either. Both clients install the cert files and then ask me for the L2TP secret (which was set on the file), but then they oddly ask me for a username and a password, which I don't know where I could possibly get those from. I attempted all of my logins, and some whacky guesses that were frantically pulling at straws. If there's any more information I could provide let me know.

  • Slower wireless speed in Ubuntu 12.04 (64-bit) on Asus USB-N13

    - by PhantonTurtle
    I have an Asus USB-N13 which I use for wireless internet on my desktop. The download speed I get on Windows 7 (dual-boot) is 15.22 Mbps. On Ubuntu 12.04 (64-bit) I can only get 1.09 Mbps. I asked a question about this on the Ubuntu forums as well, but I did not get an answer. Here is the output from lsmod | grep rt which gives me, parport_pc 32866 0 rtl8192cu 103297 0 rtl8192c_common 75767 1 rtl8192cu rtlwifi 111202 1 rtl8192cu mac80211 506816 3 rtl8192cu,rtl8192c_common,rtlwifi cfg80211 205544 2 rtlwifi,mac80211 parport 46562 3 parport_pc,ppdev,lp I installed the drivers from Realtek (my chipset is Realtek, not Ralink) but that did not work.

  • off-the-shelf HDD in Dell Optiplex 755 - Invalid Replacement - Press F1 when rebooting

    - by Eric Liprandi
    Hi, I recently put an SSD into my work Optiplex 755. Since then, every time the system boots or reboots, I get prompted to hit F1 to continue with a message like HDD replacement is not valid. The system works just fine. What I am gathering from Dell's website is that I left the original drive internally as a data drive. And apparently the Optiplex does not support 2 drives in the configuration we purchased originally and complains. Any suggestions on how to get rid of this message? some suggested the MEBx or whatever from Intel and to turn it off, but I did not succeed earlier. It's not a big deal 80% of the time, but I regularly work from home and occasionally need to fire a reboot and well, you don't get the BIOS screen remotely :) Regards, Eric.

  • Can Windows 7 Jump Lists be made to behave like menus when dragged out with a mouse?

    - by FocusStealer
    On a traditional menu, if you mousedown on the menu title, drag down, then release on a menu item, it will trigger that menu item immediately, e.g. in Notepad: Left mouse button down on File Drag down to New Release mouse button will start a new file without requiring an additional click. However, when dragging out a Jump List on Windows 7, you must additionally click the desired item to launch it. Is there any way to change this behavior?

  • Compaq 610 fan is constantly on and noisy, base is fairly hot too

    - by Dave
    The fans on both of my HP Compaq 610s are constantly on and the base is fairly hot and I don't know if this is standard issue. HP assures me that this is unusual and that I should return them as DOA. Because both laptops have this problem, I'm thinking that this might be a design flaw rather than a one-off problem. I've updated the BIOS and using their recommended power settings. Am I missing something? Is there anything I can do to fix it?

  • Config files for xterm

    Is there any config files for xterm for default settings? For example, on my system, xterm start with black text on white background, and I want it the other way around. I can do it by starting it with: xterm -bg black -fg white. I want to set in a config file that if I run it without arguments, it will start with these options.

  • How to route HyperV VMs traffic through host VPN

    - by Random
    I'm using Windows 8.1 Pro with HyperV. I have several VMs for development, all of them connected with host via Internal adapter using network addresses: 192.168.10.0/24 Where: 192.168.10.1 is my host's Hyper-V internal NIC address. When I'm not in my office I use 3G usb dongle an dialup VPN connection. I would like to route traffic from all existing and future VMs through the VPN. In best scenario traffic would be routed only partially to the local company network addresses 10.1.1.0/24 I don't want to use sharing because I'm switching between WiFi, USB 3G dongle and VPN. Moving to other virtualization is also not an option for me.

  • YouTube videos not working

    - by André
    I have a problem with watching YouTube videos. It says: "An error occurred, please try again later". I've tried loading different videos and that's what it says to all the videos I try to watch. I've tried using another browser, clearing cache + cookies etc, but none of that really worked out. My operating system is Windows 7 Home Premium, I use Google Chrome as my browser. And the YouTube videos was able to be watched earlier. I suspect that it has something to do with the PC, since I've got YouTube working on my laptop earlier. Not sure if it still works on my laptop though. Hope I've given enough information for you to help me out with this problem. Feel free to ask if there's anything else you need to know. Hope you can/will help me out. :)

  • Mac OS X Terminal get in Macintosh HD? For using Git and Github

    - by user63119
    I wanted to get started with using Git and Github especially for installing Web software to my htdocs directory. htdocs is the folder in which you put all your websites that then run by using MAMP -- Apache server, PHP, MySQL and stuff. This not the real problem though, the problem is I am in the terminal and see this: imac-van-jeroen-*******-2:~ JeroensiMac$ And using cd ~ or cd .. just results back in the line above, which is usual. The problem is that all my applications and everything really is not on my user but in the Macintosh HD. Macintosh HD/applications, or Macintosh HD/applications/MAMP/htdocs/ I want to be in the Terminal and go to my Macintosh HD (is this referred to as being superuser?). I want to know if this is just my fault for installing everything on my Macintosh HD instead of Macintosh HD/users/JeroensiMac/~. Also I would like to know if its possible at all, and I am just missing something. And If I am not doing anything wrong is it safe to use Git(Github) with directories in my Macintosh HD?

  • X forwarding over SSH from Mac to a Linux box

  • How to get a good current VMWare browser appliance?

    - by Brooks Moses
    I'd like to have a small VMWare virtual machine that runs a copy of Firefox, with Flash enabled. (Or some equivalently-capable browser.) I tried doing some Google searching with no luck finding good keywords, and tried looking through VMWare's "marketplace" of VMs, but all I found were things from 2006 or so. Is there a reasonably easy way to get a current one? Ideally, I'd like to just download one somewhere, but in the alternative, a quick how-to guide would be useful. I know I could go through the whole process of getting a full-Linux-install VM and setting things up, but that seems like quite a lot of trouble and ends up with a pretty heavyweight solution to the problem, so I'm hoping there's a simpler way.
