  • Monitoring Maximum Process Network Activity

    - by user125973
    We have a collocated server on which we run some OpenVZ hosts. Recently, we have had to pay a lot extra we keep exceeding our bandwidth quota. Our quota is 5 Mb/s but we have spike to almost 50. I looked at the graphs and there are some spikes happening at some intervals. I want to know which process is causing this so I need a tool that monitors the processes and gives me the one with the maximum instant traffic (It doesn't matter how much traffic we have as long as we don't exceed the 5Mb/s quota). Does anyone have a recommendation for this? My hosts are CentOS 5 with OpenVZ so I can see all the containter processes from the host, if that helps in any way.

  • Vista locks up after ~10h. of activity

    - by Naomi
    Hi everybody, I am experiencing a problem: Windows Vista completely freezes/locks up lately... It happened today twice - the mouse and keyboard stopped responding and I had to re-boot. I checked the Application Events Log and I see these two errors: Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. and then The following boot-start or system-start driver(s) failed to load: SASDIFSV SASKUTIL I checked Help online and it points to http://technet.microsoft.com/en-us/library/cc756390%28WS.10%29.aspx and suggests Updating the drivers. I'm not sure why would I have problem with drivers and if so, how can I find out which drivers to update? Can you please help me? Thanks in advance.

  • Is keeping the primary hard disk as disk C: still relevant?

    - by Jeremy French
    Back in the day, floppy disks were a: and if you were lucky b:, then when permanent storage came along c: was the default for hard disks (as I remember it) Now that many computers no longer have floppy disks is it possible to have your primary hard disk as A: is the convention out dated? Removable drives (like DVDs and flash readers) now seem to take lower precedence than permanent storage so it is a bit of an oddity that floppy disks should have higher letters.

  • System Event ID 11 Disk

    - by Guy Thomas
    Upon starting Windows Server 2008 R2 I get this error message: Event ID 11 Disk The driver detected a controller error on \Device\Harddisk3\DR3. There are also also 3 more similar messages for Harddisk 2, 4, and 5, but not zero or 1. Checking the event viewer reveals it's been going on for 3 months. I ran chkdsk - no bad sectors. Any advice on the cause, better still, a solution?

  • Wireless Activity Monitoring for PCI DSS Compliance

    - by dkusleika
    In an effort to be PCI DSS compliant, I took a trustkeeper.net questionnaire. I failed the question that asks Is the presence of wireless access points tested for by using a wireless analyzer at least quarterly or by deploying a wireless IDS/IPS to identify all wireless devices in use? (SAQ #11.1) My only wireless access point is outside my firewall, so even if you cracked my wireless you couldn't get inside my domain (unless you crack that too). My firewall doesn't have IPS and I couldn't tell if it had IDS. I looked around for a wireless analyzer, but what I found was $500, which is a little pricey for my size business. And even if I got it, I'm not sure I would understand what it tells me. Surely there are smaller/less sophisticated businesses that take credit cards and have solved this. My questions are: What are the risks if someone were to crack my wireless? (Could they read all internet traffic? Just wireless traffic? Just use my internet connection?) And what is the best/cheapest way to test my connection point quarterly? Should I buy the $500 analyzer? Domain is Windows Server 2000. Firewall is Sonicwall Pro 2040. Router is 8 port D-link.

  • How do I mount a raid disk

    - by Devator
    So I screwed up my grub.conf file on a CentOS system and I'm in recovery right now (it's only a test dedicated server). My disks are /dev/sda1 and /dev/sdb1 (RAID 1). Now I need to mount /dev/sda1 and make changes to the grub file, however those changed need to be reflected on the second disk aswell. How do I mount these RAID disks? I can mount one using mount -t ext3however it will damage the RAID array.

  • Creating an office network and monitoring all activity without a proxy

    - by Robert
    We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

  • External USB disk drive cannot be remounted in Windows XP

    - by jackhab
    I have Maxtor Basics Desktop 1TB external USB drive connected to Windows XP. The dirve's firmware puts it to sleep after 10-20 min of inactivity and then the drive cannot be mounted unless I reset it via power connector. While in sleep mode I can see the device in the Device Manager under both Disk drives and USB sections. Is there a way to get the drive out of sleep mode without hard reset? Thanks

  • USB stick appearing as hard disk drive, not removable storage device

    - by Paul Lammertsma
    I just plugged in a very simple 1GB USB stick from the office in hopes of making it a Fedora Live USB stick. For that to work, I need a removable storage device, or else it won't appear in LiveUSB Creator's list. Explorer lists my USB stick as a hard disk: LiveUSB Creator indeed doesn't show it in the device list: Is there any way of forcing Windows to see the stick as a removable storage device?

  • Best filesystem choices for NFS storing VMware disk images

    - by mlambie
    Currently we use an iSCSI SAN as storage for several VMware ESXi servers. I am investigating the use of an NFS target on a Linux server for additional virtual machines. I am also open to the idea of using an alternative operating system (like OpenSolaris) if it will provide significant advantages. What Linux-based filesystem favours very large contiguous files (like VMware's disk images)? Alternatively, how have people found ZFS on OpenSolaris for this kind of workload?

  • [Ubuntu]df Total size is not correct compared with the size of the disk

    - by John John
    I'm running Ubuntu Squeeze and on one of the partitions df is showing the Total size as 335G: Filesystem Size Used Avail Use% Mounted on /dev/sdb 335G 225G 94G 71% /mnt However in the past it was showing as 360GB (which is the actual size): fdisk -l /dev/sdb Disk /dev/sdb: 365.0 GB, 365041287168 bytes lsof +L1 does not return anything (and anyway if this would be the case the Total space should not be affected.) On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.

  • VMware Fusion disk size

    - by churnd
    I have a Windows XP x64 install in VMware Fusion. The amount of space that the VM reports as used (C:) is ~20GB. However, the amount of space the VM is taking up on my disk is 30GB. Why the inconsistency? I do not have autoprotect enabled, nor do I have any snapshots I'm aware of. I have defragmented the drive and used Drive Cleanup from the VMware settings.
