  • About memory cache of Linux

    - by cheneydeng
    I'm running a python script to do some statistics and the actually memory which used is low,about 10%.And no other process cost more memory.However,when i use free -m and it shows that almost 95% memory has been used.The point is that my script should do a lot of read from files,so i wonder if there's any mechanism of Linux memory cache that caused the problem?echo 1 >> /proc/sys/vm/drop_caches works,but it seems manually.How can i reduce the memory cost and doesn't make a bad effect on reading files?

  • Increase the number of concurrent users on Windows Server 2008

    - by gentlesea
    I have a Windows Server 2008 R2 running and I am able to connect to it using 2 different users via Remote Desktop Connection. Since a colleague and me are working on the server almost all the time and another colleague also wants to connect there is always the need to disconnect one user which is bad. Is there a possibility to increase the number of allowed users? On another server there are more than 2 users allowed. What is different there?

  • Windows update on netbook requires CD (hint, there's no CD drive)

    - by bwooceli
    An "Important" update for Microsoft Works (via Windows Update) on a Dell netbook gets about halfway through and then pops up with the super-awesome "Please insert Microsoft Works 9.0 disc" message. Of course, the netbook has no CD rom drive, there is no handy folder (that i can find) containing "Works9.msi", and I have no Works9 disc. It wouldn't be so bad, except the update keeps coming up everytime WU runs. Any suggestions?

  • A free WebDAV client for Windows?

    - by Brian L.
    I'd like to copy files from a network drive to a SharePoint site (perhaps as a mapped drive). What's a good client to do so? Obviously Windows (XP) Explorer is bad, I"m trying RichCopy at the moment. Any opinions on CoreFTP? Are there any recommended open-source WebDAV clients?

  • Virtualization software for windows 7

    - by user23950
    I've been using Shadow User and Deep freeze for windows xp. But I don't think its compatible with windows 7. Do you know of any application that can achieve the same thing? Please don't tell me to use Returnil virtual system because I've had a really bad experience with it when I'm using xp. The system just restarted over and over. And I have just reformatted by that time.

  • Tips for Domain Name Management?

    - by bofe
    Expired domain names = downtime for websites. Downtime = bad. How does your organization make sure domain names have been renewed? I believe ICANN requires registrars to give a notice at 60 days and 30 days, but these can easily get ignored -- especially with a large amount of domains. Does your solution work for a large amount of domain names? ( 100) Is it registrar specific?

  • How can I create an Computer Icon on Windows 8 Server Beta's Desktop?

    - by bernd_k
    For some bad reason Microsoft decided to remove all standard desktop icons besides the Recyle bin. It is easy to create shortcuts to each single disk using create shortcut method. But I would like to have the computer icon too. I guess there will be an increased demand to create useful shortcuts on Windows 8 Servers Desktop, because the metro surface 'on the backside of your screen' is just impractical.

  • How much audio latency is noticeable by human brain?

    - by Borek
    I am choosing a wireless headset for my PC (I hate cables) and am looking at Sennheiser RS 170 / 180. They supposedly sound great, however, there is a 25ms audio latency. I've heard that this is OK when watching TV or listening musing but is bad for games. The question is - has there been any research / hard data that would show how much of a delay is noticeable by human brain? 25ms doesn't sound like a lot but I may be wrong.

  • Windows 2003 routing by port

    - by vansickle
    I have remote Windows 2003 server with two network interfaces e.g. Cn1 and Cn2. I need that all traffic goes through Cn1 except for one port (for me it's 3389, rdp for administration) that works over Cn2. Currently when I setup all connections work through Cn1, I completely lose connection over Cn2 - and can't connect to server via RDP over Cn2. Now I used static routing based on my ip address (which can changed - so it's bad).

  • SSD: NTFS vs EXT4

    - by Joshua
    Always when I read about SSD usage under Linux, the advice is to disable journalling in Ext4 (or use Ext2), since it's too bad for your SSD. But in all articles about SSD tweaks for Windows, I never see any mentions that you should disable NTFS journalling, or that you should stick to FAT32. I know Ext4's journaling is more advanced, but is it so much more damaging to a SSD than that of NTFS? Or are Linux users just a little bit more cautious?

  • Encrypt windows 8 file history

    - by SnippetSpace
    File history is great but it saves your files on the external drive without any encryption and stores them using the exact same folder structure as the originals. If a bad guy gets his hands on the hard drive it could basically not be easier to get to your important files. Is there any way to encrypt the file history backup without breaking its functionality and without having to encrypt the original content itself? Thanks for your input!

  • Postfix sendmail bypass restrictions [on hold]

    - by EnEli
    I have setup a postfix/dovecot mail server and all thing work fine! BUT: I use virtual mailboxes and when you try to send a mail to a non existent mailbox via telnet postfix will punch you... But if you use sendmail, all restricitons are bypassed... This is bad becuase dovecot does not know what to do with this mail! It will stay in the queue for ever... How can I force sendmail to use normal smtp?

  • Quick method to determine SSD drive health?

    - by ewwhite
    I have an Intel X-25M drive that was marked "failed" twice in a ZFS storage array, as noted here. However, after removing the drive, it seems to to mount, read and write in other computers (Mac, PC, USB enclosure, etc.) Is there a good way to determine the drive's present health? I feel that the previous failure in the ZFS solution was the convergence of bugs, bad error reporting and hardware. It seems like this drive may have some life in it, though.

  • Level 3 Communications Monitoring

    - by thursdasy
    Does level 3 Communications offer any type of map of current network status? It seems our connection here is getting high latency through their network. Also what is the experience asking them questions about if one of their appliances is malfunctioning or being overloaded because you are receiving bad latency in their network?

  • USB ports not working after restoring back

    - by jmainock
    After restoring this computer with a backup it appears that 2 of the 5 usb ports no longer work. I'm thinking that there is something corrupted on the backup disk causing the failure. When I plug in a usb keyboard to these ports the system will not recognize the new hardware on the 2 bad ports but does recognize new hardware on the remaining three ports. All the ports were working prior to the restoration.

  • Is it OK to have a diferent hostname to fqdn?

    - by Cameron Ball
    I have a server with fqdn git.mydomain.com (this is in DNS) but I don't really want the machine to have git as its hostname. Right now I have the hostname in /etc/hostname set as (for example): mycustomhostname And in /etc/hosts I have 1.2.3.4 git.mydomain.com mycustomhostname (Where 1.2.3.4 is my server's IP) I've read that the first component of the FQDN should always be the unqualified hostname, so is what I'm doing bad? If so, what is the correct way to do what I want?

  • Virtual PC in Remote Desktop session runs very slowly??

    - by Michael Bray
    I have a VPN to my work which is quite fast... I Remote Desktop to my work PC, which is running a Microsoft Virtual PC. Working with the PC while I'm actually at work isn't too bad, but when I try to interact with it over the remote desktop, it is VERY slow to respond. Even simple typing can be slow, but screen painting and response time is painfully obvious. Any suggestions to help speed it up?
