• X11 not sending windows to remote computer matlab

  - by MZimmerman6

  I am trying to set up my home desktop, running OS X Mountain Lion, to basically do a bunch of grunt work for me remotely. I have set up ssh, and am able to remotely control the computer fine, but the issue comes in when I try to run X11 apps, like MATLAB, remotely and get windows to pop up. Every time I try to bring up a new window it either opens that window on the remote computer (not the one I am using to control it), or it tells me it can't find a display. here is how I am setting up my ssh assume my matlab alias is set up properly, which it is. ssh -X [email protected] matlab -nodesktop figure; This will open the window on the computer I am SSHing into, and not on the remote one. Basically I want that window to open on the computer I am remoting from. I changed my SSH X11Forwarding and stuff to be yes in ssh_config and sshd_config. Any other suggestions?

  - by Wasswa Samuel

  I have centOS 5.5 installed on virtual box it has no GUI so every thing is command based. I want to make a folder in centOS which i can share with my windows 7 host OS such that i can send files to and fro seamlessly. I am new to linux and i managed to install samba. I looked up some tips on net but i ended up getting confused and none of them worked.

I am completely lost.please help.

• Hyper-v dynamic memory client machines always use maximum memory

  - by Eric P

  When I create a virtual machine in Hyper-V and set it up to use dynamic memory, the virtual machine will always use the maximum memory within the virtualized OS. Hyper-V will show the assigned memory at 514mb, but when I log into the server and pull up task manager, it will show 90% memory used. When I bump the maximum memory up to 4gb, I get the same result: 90% memory usage. Nothing is even running on the virtual machine other than a clean instal of Windows Server 2008 R2. I have also tried it with Windows 7 with the same results. Is this the expected behavior or is something setup wrong

• Is it possible to change User's Home Directorys permission in OSX?

  - by Sosiska

  Most of your staff uses OSX as main operation system. The problem is that recently we were attacked with some odd malware: users are getting zip-file via mail, and when they open this zip file, they execute a binary keylogger malware, that is inside this zipped file. (One click is enough). We have some non-technical limitations and due this limitation we can't configure user's mail servers. But actually we have physical access to their laptops. As far as I know, there is possible to mount user's home directory without "x" (execution) permission in Linux and *BSD. So users can't run some binary file inside home directory. Is it possible to configure OS X so that user can't execute files inside /Users/?

• dual-boot does not work

  - by elyashiv

  I have a PC with linux-mint installed on it. I wanted to install win-7 along-side, for some reasones. what I have done is: create a bootable USB-stick with Ubontu ios. restarted the computer, this time with Ubuntu (running from my disk-on-key). created a partition on the main HD using GPart. formated the partition to NTFS. restarted the computer, this time through the installation CD for win-7. installed win-7 with normal settings. that all worked, and I'm writing this through win-7. the thing is - when I boot my system, I don't get to choose what OS to run. I checked the settings in msconfig, and in boot label it has just win-7. how can I boot linux?

• Mac | Router not assigning the IP address.

  - by Vaibhav Bajpai

  I recently installed Mac OS X 10.6, however the ethernet state is down. The assigned IP is 169.x.x.x. When booted the live USB of Ubuntu, I properly get an IP assigned in the range 192.168.1.x from the router 192.168.1.1 I am using the same router and same ethernet line. I tried to ping to 192.168.1.1 from my Mac and I get a host down message. I tried to manually assign the IP and set the router IP to 192.168.1.1 but still the router is unreachable.

• I have to manually enter the pwd when I login at school and when I come back home with my laptop (DELL E6410)

  - by Bong Paduano

  I didn't have to do this the first 3 months of me going to school. My laptop used to be able to connect to my Home WiFi and school Wifi automatically then after the 3rd month something changed and eversince then I literally have to manually enter each of the Wifi passwords in each location each time I try to connect to their respective WLAN. I tried adding each WiFi networks in the "Manage wireless networks" section in the Network and Sharing Center but everytime I login to one of the location, the created network disappears and I did this more than once. I tried restoring the OS back but to no avail. Can someone please assist me on this issue. I'm not sure if this issue has been addressed in this website but I haven't seen any similar question in here. I appreciate any help anyone may be able to share.

• Is there a Google Authenticator desktop client?

  - by cwd

  I am using Google Authenticator for 2-step authentication. I like how I can use a code and verify my account using my phone: I realize that the app was designed to run on a device other than a computer to increase security for the computer (in case that it is lost or stolen), but I would like to know if there is a way I can run Google Authenticator on my Macbook. Now, per the Google Authenticator Page it will not run on a desktop: What devices does Google Authenticator work on? Android version 2.1 or later BlackBerry OS 4.5 - 6.0 iPhone iOS 3.1.3 or later However there are several emulators for developers and so I wonder if it is possible to run one of these emulators and then run Google Authenticator with that. I do realize this is not a best practice - but I'm less worried about my laptop getting stolen and more worried about someone just hacking the account. So my question is this: Is it possible to run it on the desktop, even though it is not meant to be / not recommended?

• Can a NAT close out VPN connections?

  - by Scoop

  I have a client running on a VPN behind a NAT. The client becomes inaccessible after a while if it is not "active". The VPN software is PPTP and the OS of the client if Debian. I'm unsure about the exact cause of what makes it inaccessible or if it is another piece of software that is causing the problem. But my current thing I am trying to figure out is if the NAT is healing and causing the client VPN to become inaccessible. Could this be causing the problem or should I look elsewhere?

• Any good reason to open files in text mode?

  - by Tinctorius

  (Almost-)POSIX-compliant operating systems and Windows are known to distinguish between 'binary mode' and 'text mode' file I/O. While the former mode doesn't transform any data between the actual file or stream and the application, the latter 'translates' the contents to some standard format in a platform-specific manner: line endings are transparently translated to '\n' in C, and some platforms (CP/M, DOS and Windows) cut off a file when a byte with value 0x1A is found. These transformations seem a little useless to me. People share files between computers with different operating systems. Text mode would cause some data to be handled differently across some platforms, so when this matters, one would probably use binary mode instead. As an example: while Windows uses the sequence CR LF to end a line in text mode, UNIX text mode will not treat CR as part of the line ending sequence. Applications would have to filter that noise themselves. Older Mac versions only use CR in text mode as line endings, so neither UNIX nor Windows would understand its files. If this matters, a portable application would probably implement the parsing by itself instead of using text mode. Implementing newline interpretation in the parser might also remove some overhead of using text mode, as buffers would need to be rewritten (and possibly resized) before returning to the application, while this may be less efficient than when it would happen in the application instead. So, my question is: is there any good reason to still rely on the host OS to translate line endings and file truncation?

• Can an ESX server under heavy load cause cpu spikes on guest VM's?

  - by ReferentiallySeethru

  So we have a number of vm's running on an ESX 4.1 server for product testing. The ESX Server is at times under heavy load. We've been experiencing high CPU levels during some use cases, but we can't always duplicate this. If the ESX server as a whole is under heavy load could this cause guest machines to show high CPU usage? To ask it a different way, if the guest machines require more cpu resources than the server has, how does this affect CPU usage as indicated by the OS and process?

• How to work with processes?

  - by Viesturs

  I have seen similar questions here, but I didn't get my answer. Maybe it's because I am new to all this and just don't understand. I want my app to work mostly as an indicator. And if user would start it again it would check if it is already running, if it is then give all the input data to that process and quit. So first I need to check if it is running. I saw the answer where you can make a file witch when the program starts and then check if it exists... But what if someone would delete it? Can't I just ask the OS if there is process named "myApp" or something? The next thing I don't really get is how to communicate with the process. How do I give it the input data and what is it going to do with it? Does it work just like starting a new app, through the main() method? I am trying to create this using Quickly. So it would be nice if you can give me some python examples or link to something like that.

• Unable to mount cifs in redhat 6

• Upgrading Fedora to Current Version - Dependent Applications Concerns

  - by nicorellius

  Is it possible to upgrade to Fedora 11 and still keep the server functional (it's running Fedora Core release 6 now, with MySQL 5.0, PHP 5.1 and Apache 2.2)? I have a Customer Relationship Management system on there and it is required on a daily basis. I am trying to figure out if I should upgrade (and whether that will cause huge problems) or if I should start over with a new OS (like Ubuntu) and install the CRM fresh, with updated version of MySQL, PHP, Apache, etc. I ask because I am not really the sysadmin, but have but put in charge of this server.

• get focus only by clicking the title bar of xterm

  - by sandyleo

  ...I've suffered this problem many times and so do my colleagues Sometimes after you stroked some keyboard and mouse combinations this behavior showed up : you have to click a xterm's title bar to focus on that term so that you can input, instead of any places in that window. Whatever you do, minimize, resize don't help. This only thing you can do is logout that session but all the working history will be gone(of course I can save that but it's awkward) I'm eagerly wondering is there any solutions to this? I use ctrix XenApp plugin 11.0. The other platform info: Linux 2.6.9-67.ELsmp x86_64 OS: RedHat Enterprise Linux 4.0 U6 xterm:X.Org 6.8.2(192) THanks!

• Starting Apache through XAMPP is not working

  - by nogamo

  I've checked the error logs for this particular problem and it seems no access can be made to port 80. (OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address [::]:80 Turning the Windows firewall off didn't work, so I'm a bit lost. All of this is running on my laptop so I don't have my own "server" per se but I was under the impression that this would work without the need for one independent of my own personal computer. How would I solve this?

• Connecting via url to a server that is on the same network as me

  - by Axehead

  Good day, I'm having problems with the ftp server I've just set up. I've already managed to configure my modem and wireless router to open up port 21 and setup ftp in my server. But It seems that when I try to connect to it when I'm in the same network as the server via URL, (ftp://mydomain.com) it redirects me to the modem's web interface. But then when I try to connect to it outside the network using a different internet connection. It succeeds. It also succeeds when I'm in the same network and I go to ftp://192.168.., the server's local IP. Am I supposed to adjust something in the modem or router? Or is this a different problem altogether? BTW I'm using Windows Server 2008 r2 as my server's OS and using IIS for ftp.

• Windows 8: Multiple monitors with varying DPI? [closed]

  - by Sid

  Possible Duplicate: Dual monitors on Windows - How do I set a different DPI or text size on each monitor? I'm running Windows 8 on my Macbook Pro Retina (220dpi) which has an external 24" monitor (~96 dpi). In Mac OS 10.8.2, the display settings seem ok and I can actually use both displays without usability issues. I don't know what scaling settings etc it uses but it looks fine. On Windows 8, however when I boost the DPI settings to take advantage of the retina display, it blows up the display on the external monitor - text is giant sized. How can I tell Windows 8 to use the real DPI settings of each monitor? NOTE: I'm not asking for Windows 7.

• No boot option after installing Ubuntu 12.04 LTS on Acer Aspire 4736z with Live CD

  - by utamaku

  I am facing a problem. After installing Ubuntu 12.04 LTS using Live CD, at the reboot there is no boot option to choose the OS. I directly get logged into my Windows 7. Before that i was having an issue with the 'nomodeset' if not mistaken .After ticking [x] on the nomodeset, i can install my Ubuntu, but got stucked again at choosing the partition option. So i did 2 partitions for Ubuntu, 1 partition as ext3 for / and the other 1 for swap. Which enabled to proceed until the finished installation dialogue, and after that system wants to reboot .It takes some time and gets stuck at the screen doing nothing, doesn't reboot at all. I did forced shutdown then rebooted again which directly logs me in windows 7 without boot option. In win7 the partitions for Ubuntu is gone. I tried the boot-repair thing and it doesn't help .It just shows up the _ Blank Cursor (terminal thing i guess). I typed boot repair but still the same result. I am using Acer Aspire 4736z. Please somebody help me with this issue.

• Utility to take daily screenshots of a webpage

  - by Kevin L.

  I would like to have a visual history of my Tomato bandwidth graphs, so that I can roughly/manually correlate them with some other factors. Tomato can squirrel away the actual data points, but I'd rather not deal with importing it into some visualization tool. For sheer simplicity, a single image per day would be preferable. I'd like a program that can wake up at say, midnight, take a screenshot of a given webpage (the URL will always be the same), and save that image to a folder, maybe named after the date/time. I'd prefer OS X, but Windows and Linux are fair game too; I use all three. Any suggestions?
