  • How can I make the NetworkManager work?

    - by Yang Jy
    I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

  • rsync server side limit bandwidth/connection

    - by c2h2
    In a VOIP application, I have upto 3000 clients rsync audio files from there linux server in a daily, server is placed at a data center (10Mbps in/out bound), the server works as a VOIP sip server running FreeSWITCH (low ping latency should be ensured.) Therefore I would like to have server side control of rsync which controls: Limit total outbound bandwidth. Limit total number of connections. (Reject clients while at max number of connection and let it retry after a specific time frame.) OPTIONAL: list/kill individual connections. Normally I would use ssh + rsync + pem_keys with some extra options, but above requirements are not feasible by simple command lines. Can anyone point me some direction. or show some scripts/tools? I would also probably integrate them and release on github. Thanks!

  • Limit WSUS replication to only certain product classifications

    - by MDMarra
    I have four WSUS 3.0 SP2 servers that are geographically distributed. The server at our main site (we'll call it WSUS1), is the main WSUS server. All manual and auto-approvals happen here. The other three WSUS servers are replicas of this server. Currently, we are only controlling desktop OS updates through WSUS. I would like to control server OS updates through WSUS as well. There is no need for all of these server updates to be on WSUS servers at the remote sites. The only server that would need a copy of them is WSUS1. Is there a way to keep my current infrastructure as-is and add server OS updates only to WSUS1, even though the others are set up as replicas, or will I need to configure an additional WSUS server that's not replicated?

  • Pull Request Conversations, Inline Diff Enhancements

    [Do you tweet? Follow us on Twitter @matthawley and @adacole_msft] We deployed a new version of the CodePlex website today. Pull Request Conversations Previously, the only way for project members and users who submitted pull requests to converse was via e-mail. This complicated the review process and made conversations isolated and difficult to track. For this release, we’ve added functionality that enables you to have those same conversations within the pull request page. When you view a pull request, you’ll now see “Comments” and “Changes” tabs, with current comments displayed. Inline Diff Enhancements We tweaked the inline diff experience to make it easier to traverse diff blocks. When you open up the inline diff experience, you’ll now see up and down arrows. To move between the diff blocks, you can use those arrows or utilize the available keyboard shortcuts. Lastly, we have also brought the inline diff experience to the source control changes page for project and fork changesets. You can see both enhancements live by viewing the associated pull request or changeset changes on WikiPlex. The CodePlex team values your feedback. We are frequently monitoring Twitter, our Discussions, and Issue Tracker. If you have not visited the Issue Tracker recently, please take a few minutes to suggest or vote on a feature you would like to see implemented.

  • Force '^C' to be printed when editing current prompt, then aborting it

    - by Stefan Lasiewski
    This is the opposite of Prevent “^C” from being printed when aborting editing current prompt. I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character. I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX.

  • Is there an easy way to disable this laptop's touchpad?

    - by sestocker
    Specifically, I'm on a Dell Inspiron 1525. I'd like to disable the touchpad so that I can re-enable if my mouse were to run out of batteries (so physically breaking the connection to the motherboard or uninstalling the driver will not be the best options). In the Control Panel, when I go to "Mouse" and find the touch pad, there is no disable option. Any ideas? Edit: I am on Windows 7. There is a driver on the Dell site that might allow an option to disable it, but I cannot install it on Windows 7.

  • Filtering attachment types in Google Apps (free Google Business)

    - by Ernest
    We have Google apps in our company for mail delivery, our business can't pay the business version yet, however, we need to control the attachment types that employees download. We recently switched from another hosting provider who recomended us to plug Google Apps for mail when we moved the domain, we had a firewall before which was able to prevent certain file types to be downloaded. I know the business version has section for filtering mail (postini services). Is there a hack around my problem? Anyone ever had this problem? Thank you! UPDATE: The main problem is gmail apps uses ssl connection, can this be changed ? how can i get the firewall to filter files only allowing *.doc, *.xls y *.pdf.

  • How do I write to an outer truecrypt volume when the inner volume protection prevents writng?

    - by con-f-use
    In a nutshell After some time using the outer volume of a hidden volume in Truecrypt I cannot write to the outer volume anymore. The protection of the inner volume always kicks in before. How do I fix this? Details I'm using truecrypt's two layered encryption of a USB stick. The outer container carries my semi-sensitive stuff while the inner hidden values has a bit more valuable information. I use both, the inner and outer volume regularly and that is part of the problem. Truecrypt can mount the outer volume for writing while protecting the inner. Usually the inner volume, when not protected this way (or mounted read-only) would be indistinguishable from free space. That is of course part of the plausible deniability scheme of truecrypt. At the beginning, everything worked as expected. I could copy and delete data to the outer volume as I pleased. Now it seams that I have written and deleted enough data to have filled the outer volume once. Despite the write protection Ubuntu tries now to write to the continuous "free space" that is the inner volume. It does that although enough other free space is on the outer volume. But on this free space there used to be data so its fragmented and the file system write prefers continuous space. The write on the continuous free space of the outer volume of course fails (with the error message in the picture above) as Truecrypt's inner-volume-protection kicks in. The Question I know this is expected behaviour, but is there a better way to write to the outer volume that does not attempt to write to the hidden free space at the end? The whole question could be more generally rephrased to: How do I control, where on a partition data is written in Ubuntu?

  • Outlook 2010 reminders keep popping up even if closed

    - by LapplandsCohan
    Today when I got to work and started my computers I got a event reminder for my last events last friday. I closed the reminder, but perhaps 10 minutes later it pops up again, and another 10 minutes later it popped up yet again. As the day is passing all my reminders for this day is added to the list of reminders that keep popping up 10 minutes after that they are closed. I've tried both the repair function in Windows Control Panel -- E-mail and the scanpst.exe program, but none of them solved the problem. I've tried outlook.exe /cleansniff and outlook.exe /cleanreminders, but that didn't help either. Reading on the net there seem to be some reports with this for reoccuring calendar events, but my affected events are one-timers. How can I get the closed reminders to stay closed? Update: I noticed that I have 282 drafts of the meetings that I keep getting reminders of.

  • Can I fine-tune my screen brightness? (Ubuntu Studio, Thinkpad T420s)

    - by Dan S
    I am in a similar situation as question Can I fine-tune my screen brightness? . For me, Thinkpad T420s and Ubuntu Studio 11.10. The brightness keys work fine but the increments are too large. I have the /sys/class/backlight/acpi_video0 and I can see the value of actual_brightness changing as I use the brightness keys - it changes between values 0,3,6,9,12,15. None of the listed answers for fine control works here, as follows: As the root user I can echo integers to brightness in the above folder. As an ordinary user I cannot. I do not have /usr/sbin/gnome-power-backlight-helper (because I'm using xfce perhaps?), and not sure what package it's from or if installing such a package would make sense since it's not what's currently managing the backlight. How can it be done, please?

  • How to configure something like "Reflexive ACL" on OpenBSD?

    - by Earlz
    My U-Verse modem has something called "Reflexive ACL" described as Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). This seems like a pretty good way to keep from having to maintain a firewall on each computer behind my router that gets handed an IPv6 address. It sounds about like a NAT, which for my small home network is all I want right now. Now my modem sucks as a router though, so I'm in the process of configuring an OpenBSD router to do that. I've got IPv6 supported and all that and my OpenBSD router will hand out IPv6 addresses by rtadvd. Now I want to keep people from having instant access to my local network through IPv6. How would I best do something like Reflexive ACL with pf in OpenBSD 5.0?

  • Missing 16:10 resolutions with Nvidia drivers (Can't add resolutions)

    - by Wuinny
    Hello, I have a laptop with a Nvidia 9650M GT and used the drivers that Seven brought me. It works fine but Metro 2033 tells me that i have to upgrade my drivers to play the game. So i did it. But since i did a clean install of the new Nvidia drivers, i just have 1440*900 or 4:3 resolutions. I usually played with 1280*800 or 1184*740 (for performance issue) With the "old" drivers i was able to create custom resolution (1184*740) in Nvidia control panel but now when i try it tells me that "my monitor cannot support this resolution". When i insist, it works but soon as i shut down my computer i have to recreate it.. Do anyone have a fix ? Thank you

  • How can I trace NTFS and Share Permissions to see why I can (or can't) write a file

    - by hometoast
    I'm trying to track down WHY I can write in a folder that, by my best estimation, I should not be able to write. The folder is shared with "Everyone" has "Full Control", with the files being more restrictive. My best guess is there's some sort of sub-group membership that's allowing me to write, but the nesting of groups that exists in our Active Directory is pretty extensive. Is there a tool, that will tell me which of the ACL entries allowed or disallowed my writing a file in a folder? The Effective Permissions dialog is marginally helpful, but what I need is something like a "NTFS ACL Trace Tool", if such a thing exists.

  • smartOS HPC config suggestion

    - by Andrew B.
    I'm configuring a brand new HPC server and am interested in using SmartOS because of it's virtualization control and zfs features. Does this configuration make sense for a SmartOS HPC, or would you recommend an alternative? System Specs: 2x 8-core xeon 384 GB RAM 30 TB HDs with 2x512GB SSDs Uses: - zfs for serving data to different vms, and over the network; 1 SSD for L2ARC and 1 for ZIL - typically 1-2 ubuntu instances running R and custom C/C++ code My biggest concerns as a newbie to SmartOS and ZFS are: (1) will I get near-metal performance from ubuntu running on SmartOS if it is the only active vm? (2) how do I serve data from the global zfs pool to the containers and other network devices?

  • How can I check myself when I'm the only one working on a project?

    - by Ricardo Altamirano
    I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).

  • Change Keybindings (hardware to software)

    - by Daniel
    I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

  • Windows 8 Color Settings (Window Title)

    - by xixixao
    In Windows 7, the window title's color (by default black, to see the title in the title bar fire up Windows Media Player for example) is stored in [HKEY_CURRENT_USER\Control Panel\Desktop\Colors] TitleText value. This is not the case in Windows 8, since this value is only used when using high contrast theme. It looks like noone has come up with a way to change this color yet, so my question is, where to look? What tools can I use to see dependencies, what could be the way to find this value (I rightfully hope it's not a constant in code).

  • What firewall ports do I need to open when using FTPS?

    - by anoopm
    I need to access an ftps server (vsftpd) on a vendor's site. The vendor has a firewall in front of the ftps server and I have a firewall in front of my ftps client. I understand that ports 990, 991 and maybe 989 need to be opened up for control traffic. When looking at it from the vendor's firewall perspective, should these ports be opened up for both inbound and outbound traffic? What about ports for the DATA channel? Do I have to open all ports above 1000? And should I do it for both inbound and outbound traffic? TIA for your help.

  • How to Edit PDFs?

    - by snowguy
    I typically have two needs: Scenario A. Change a single PDF page. In this case I have a PDF but not the original source file used to create the PDF. I don't want to try to recreate the document from scratch. I'd like to open the PDF and change a few things. A good example of this scenario: I was responsible for planning a big event at a campground site, I had a PDF of the site. I wanted to start with that document, highlight some parts, add some labels, remove some parts that weren't relevant. or Scenario B. Combine PDFs or extract information from a PDF This scenario usually arises because I want a single PDF deliverable that is made up of parts that are best created in different programs. In this case I have the source files for all the documents but they don't play well enough together to easily create a single PDF deliverable. For part of it, I may want to use Libre Office Writer. For another page I may want to use Gimp. Still another page I may use Libre Office Calc. I could use Writer as the master document and embed images or the Calc object into that, but for ultimate control, you can't beat separate PDF documents that are then combined. What are the best tools / processes for editing PDFs in Ubuntu?

  • Automatically Connecting to Hidden SSID WiFi Network

    - by Zack
    My MacBook Pro will not automatically connect to a Wireless network with a hidden SSID. It makes me select the "Join Other Network..." in the Airport menu (in the system tray), where I need to input the name of the network, then security type, password and wait for it to connect. This is becoming increasingly annoying to have to do every time I come back to my desk. I'm running Mac OS X 10.5 and there doesn't seem to be an option to connect to a specific network, but rather "Preferred Networks." The only network I have set as Preferred that's in range is my home network, and it still doesn't automatically connect. Making the network publicly visible isn't under my control, so I'm stuck with what's currently in place. Reader's Digest version: How do I make my MacBook Pro automatically connect to a WiFi Network with a hidden SSID without having to "configure" it every time I want to connect?

  • Where is the list of available Windows locales?

    - by Richard Cotton
    If you open the Regional and Language Options (via Control Panel), and click on the Regional Options tab, then there is a drop down list of all the available locales. Where is this list populated from? (I want to compare the settings for each locale; I'm fine with how to do that, but I need a list of locale names to loop over.) EDIT: After browsing through my windows directory (should probably mention I'm using XP), the file C:\WINDOWS\system32\locale.nls looks like a plausible candidate, but it's a binary file. Is this what I should be looking at, and if so, how do I read it?

  • VirtualBox guest not recognizing daylight savings transition

    - by user41421
    I want to test an app's behaviour during transitions in and out of daylight savings time. I therefore want to be able to set the date and time of a VirtualBox VM, (preferably from the Control Panel applet, but from a batch file is fine) and not have it "corrected" to the host's time for me. I have turned of Internet sync in the guest and that seems to have achieved this, so I wrote a couple of batch files to set the date to a value just prior to the time of transition in and out of daylight savings time. The VirtualBox guest doesn't seem to recognize the daylight savings changeover date - it just marches on past with no change of time, no message (yes - "Adjust clock for daylight savings" is enabled). Any ideas?

  • Laptop Brightness in Gnome and /proc - Thinkpad W510

    - by hakre
    I can set the brightness of my laptop screen already via /proc. I can read and change the value. Now I've set the value to 33 and then I went into gnome power management and enabled the option that it should reduce the backlight brightness being on battery. That works, the screen gets darker. If I now read out the current setting from /proc it still says it's 33. So I assume that there is another node in /proc to be used to control the brightness. The node I use so far is: /proc/acpi/video/VID/LCD0/brightness
