  • Does using a tiling window manager make a terminal multiplexer obsolete?

    - by Jan Westerdiep
    Since about half a year I have been enjoying a terminal multiplexer (tmux, to whomever it may concern), and have grown to like it. I would like to try a tiling WM as opposed to a stacked one some time in the future but cannot wrap my head around this simple question: Why would one use the splits in a multiplexer within a tiling WM? Is there an upside, besides of course the single instance you'd be running?

  • Capture Outgoing Email to One Mailbox or Account on Linux

    - by futureal
    I am looking to see if anything exists that would allow us to capture all outgoing email on a machine -- for example, in a staging environment -- and drop it in a single place, which ideally would be something we could check with a mail client. Currently we're doing this on the software level (if environment is staging, rewrite address) which is a bit ugly and leads to errors. The servers are currently on Debian Linux, using exim as the mail transport. Open to any and all suggestions!

  • What's the easiest way to 'cat' groups of files together?

    - by rajitha
    I have files with naming convention of this pattern: bond_7.LEU.CA.1.dat bond_7.LEU.CA.2.dat bond_7.LEU.CA.3.dat bond_12.ALA.CB.1.dat bond_12.ALA.CB.2.dat bond_12.ALA.CB.3.dat ... I want to concatenate all files of the same group into a single one. For example: cat bond_7.LEU.CA.*.dat > ../bondvalues/bond_7.LEU.CA.1_3.dat There's large number of these files. How can achieve this with a bash script?

  • Can a non domain server obtain it's updates from a domain WSUS

    - by NickC
    Anyone know if it is possible to get a non-domain Server to pick-up it's updates from a domain included WSUS server? Just thinking about Hyper-V host Servers, in a single server environment clearly this cannot be part of the domain because at the time the VM Host boots the Domain Controllers is not available. However is there any way to make this Hyper-V Host collect it's updates from the WSUS server.

  • Run a local script on a remote server using ssh with out having to worry about quotes

    - by Michael Irey
    So I have been running local scripts fine on a remote server: ssh user@server '`cat local-script.sh`' However, today I have a script that has both single and double quotes in it. Which causes the script to fail because the output of cat local-script.sh is wrapped in quotes. With out modifying the script itself, is there a better way to handle this? I thought this may work: ssh user@server $(<local-script.sh) But is does not seem to do anything...

  • Per bytes RAM memory acess

    - by b-gen-jack-o-neill
    Hi, I have just a simple question. Today memory DDR chips are 64 bits wide, and the CPU data bus is also 64 bits wide. But memory is stil organised in single bytes. So, what I want to ask is, when CPU selects some memory adress, it should be one byte, right? Becouse the lowest memory portion you can access is 1 byte. But, if you get 1 byte per 1 adress, why is memory bus 8 bytes wide?

  • Terminal services and screen savers

    - by Corsair
    I have a Window Server 2008 R2 server acting as a terminal server for mobile devices running a single application, but I am having issues with the screen saver popping on after ten minutes. Is there a setting in terminal services to make the screensaver settings universal? If not, how should I approach this issue?

  • Using Ubuntu switch a failing windows 7 harddrive?

    - by firefusion
    My laptop harddrive has developed some serious read errors in the windows partition. Windows 7 still boots but every single action takes an aeon, and it is definitely due to a harddisk error not due to any spyware. I'm using the Ubuntu partition now. I've ordered a new harddrive but my laptop didn't come with a Windows 7 install disk (I think I was meant to make one with the windows 7 tools). So how can I install Windows 7 on my new harddrive?

  • Moving multiple folders all at once in Outlook

    - by Luke
    Constantly at my shop, we are moving Outlook (or other email program) files between computers or Windows Installations, and sometimes, people have HUNDREDS of folders. Is there a quick way to move ALL the folders from multiple data files (*.PST) into one single file, without dragging each and every folder? No, I don't want to move the Inbox folder into the other Inbox folder for the quick move, I want something simple like selecting all folders and moving that way. Does such a method exist in any version of Outlook?

  • Windows HPC Server 08 suitability for Matlabs

    - by blade
    I want to setup another Hyper-V VM for installing Matlabs/doing some compute-intensive programming using C. I keep thinking that Windows Server HPC 2008 is designed for this sort of work. Would I be on the right track to setup a single VM with this OS and install this software? Or is HPC more for grid/distributed computing? Thanks

  • Windows7 issue in mutli- tasking and memory

    - by Nitesh
    I seeming some problem in my windows OS recently, let me first say my system configuration. processor - Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66 GHz Installed memory (RAM) - 4.00 GB (3.00 GB usable) System type - 32 bit operating system I am using two OS in this system, first one is Windows7 and the other is centOS. Well, I am using this from a long time there was no problem , and all of a sudden since from couple weeks I am facing problems in my Windows7 OS. In windows7 i was nearing using multiple jobs almost every time i log in, there was no problem but now i don't no what happen I am not able to do multiple jobs at same time. For example- 1 I am now not able to listen to music in windows media player and view photo's. All of a sudden the system stops working and does not respond and then respond after 5mins and the music get played where it got stopped after 5 mins. 2 When i start browersing internet it hangs all of sudden and doesn't respond for 2 or 3 mins and gets loading. I mean it just happens for every operation i do in the system. Even now typing was also difficult, it gets hanged very frequently even though i am doing single task. I have never come across this kind of problem before. So the first thing i did was to see the useage of the processor and the memory. Well, i thick the useage of the processor was fine, for single task the useage was some where around 3 to 5%. Well, it was something weird i found in the memory, in spite of no task that i was running it was using somewhere around 34 to 41% of memory. So i opened the task manager and click on resource monitor in performance tab. And in the memory section of the monitoring tool i found the usage of my RAM, it was something like this. Hardware reserved - 1029 MB In Use - 1430 MB Modified - 49 MB Standby - 1566 MB free - 22 MB And i could also see Available 1588 MB Cached 1615 MB Total 3067 MB Installed 4096 MB well, this if all i could find out and i have no idea why my computer is acting so weird all of a sudden and the performance problem is growing day by day and i also don't know if there is problem in Bios, i have let it for default settings from long time. please help me and Thank you in advance for reading this and helping me.

  • NFS4 / ZFS: revert ACL to clean/inherited state

    - by Keiichi
    My problem is identical to this Windows question, but pertains NFS4 (Linux) and the underlying ZFS (OpenIndiana) we are using. We have this ZFS shared via NFS4 and CIFS for Linux and Windows users respectively. It would be nice for both user groups to benefit from ACLs, but the one missing puzzle piece goes thusly: Each user has a home, where he sets a top-level, inherited ACL. He can later on refine permissions for the contained files/folders iteratively. Over time, sometimes permissions need to be generalized again to avoid increasing pollution of ACL entries. You can tweak the ACL of every single file if need be to obtain the wanted permissions, but that defeats the purpose of inherited ACLs. So, how can an ACL be completely cleared like in the question linked above? I have found nothing about what a blank, inherited ACL should look like. This usecase simply does not seem to exist. In fact, the solaris chmod manpage clearly states A- Removes all ACEs for current ACL on file and replaces current ACL with new ACL that represents only the current mode of the file. I.e. we get three new ACL entries filled with stuff representing the permission bits, which is rather useless for cleaning up. If I try to manually remove every ACE, on the last one I get chmod A0- <file> chmod: ERROR: Can't remove all ACL entries from a file Which by the way makes me think: and why not? In fact, I really want the whole file-specific ACL gone. The same holds for linux, which enumerates ACEs starting with 1(!), and verbalizes its woes less diligently nfs4_setacl -x 1 <file> Failed setxattr operation: Unknown error 524 So, what is the idea behind ACLs under Solaris/NFS? Can they never be cleaned up? Why does the recursion option for the ACL setting commands pollute all children instead of setting a single ACL and making the children inherit? Is this really the intention of the designers? I can clean up the ACLs using a windows client perfectly well, but am I supposed to tell the linux users they have to switch OS just to consolidate permissions?

  • Make a SAMBA file system visible to all users with mount_smbfs

    - by vy32
    We have a Macintosh OS10.6 server and a big storage system accessible via SMB. Right now we can mount partitions, but when we mount them they are only accessible to the user that did the mount. All other users get "Access Denied." It there any straightforward way to mount so that all users will be able to access the files? (We want all users mapped to a single SMB UID.)

  • Installing SQL Server Compact 3.5 SP2 *after* installing SQL 2012 RC0 - machine.config path include double slashes?

    - by Sigmund
    I'm trying to install SQL Compact 3.5 SP2 after I've installed SQL 2012 RC0, on a x64 Windows 7. The x86 installer goes through fine. The x64 installer fails, with the error: "Error 25543.Failed to save changes to XML file c:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\machine.config, system error: -2147024864" Note the \CONFIG (double backslash) where there should be a single backslash... any ideas why this is happening and how to solve it?

  • What's the appropriate way to upgrade Apache in RHEL?

    - by jldugger
    The version of Apache shipped in RHEL 5.4 is very old. A feature I need only shipped recently. It seems Apache upstream only ships tarballs, and omits binary packages. Obviously I could build from source, but what's the canonical way to upgrade a single package like this? Is it common procedure to drop a newer tarball in the existing SPEC, or does someone already do all this with an eye towards RHEL?

  • Linux compatible touchscreen monitor

    - by jrtokarz
    Can anybody recommend a linux compatible touchscreen monitor, the criteria are: 19inch or greater 1920x1080 or better only single touch required be able to operate in portait mode We currently have some IIyama Prolite MTS2250MS monitors but these do not natively support portait mode and we have had little success getting the touch functionality working in Linux (although they do report themselves as HID devices when plugged in). So an alternative to suggesting a monitor would be pointers to information on how we could get the IIyama monitor working in Linux.

  • script to su with password in script without root

    - by Triplell89
    I have scripted a process that involves updating symbolic links on files located on 3 different machines. On those machines exists 4 users each, who each need to have these links updated. Using su, is there a way to pass the password argument to the command on a single line, without invoking sudo as the users will not have admin rights? My only alternative solution at this point is to ssh around, however I would like to be able to do this without hardcoding in a bunch of hosts/ips.
