  • Slackware - Assigning routes (IP address ranges) to one of many network adapters

    - by Dogbert
    I am using a Slackware 13.37 virtual machine within VirtualBox (current). I currently have a number of Ubuntu VMs on a single server, along with this Slackware VM. All VMs have been set up to use "Internal Network" mode, so they are all on a private LAN, and can see each other (ie: share files amongst themselves), but they remain private from the outside world. On on the these VMs (the Slackware one), I need to be able to grant it access to both this private network, and the internet at large. The first suggestion I found for handling this is to add another virtual network adapter to the VM, then set it to NAT. This results in the Slackware VM having the following network adapter setup: -NIC#1: Internal Network -NIC#2: NAT I want to set up the first network adapter (NIC#1) to handle all traffic on the following subnets: 10.10.0.0/255.255.0.0 192.168.1.0/255.255.255.0 And I want the second virtual network adapter (NIC#2) to handle everything else (ie: internet access). May I please have some assistance in setting this up on my Slackware VM? Additionally, I have searched for similar questions on SuperUser and Stackoverflow, but they all seem to pertain to my situation (ie: they all refer to OSX, or Ubuntu via the use of some UI-based tool). I'm trying to do this on Slack specifically via the command-line. Thanks!

  • Howto enable SMPTS (465) postfix CentOS

  • Windows 7 ignores F6/F8 and will not boot

    - by P.Brian.Mackey
    I have a work PC with sophos safeguard encryption on it. Windows failed to start. When I bootup I receive an error saying a recent hardware or software change might be the cause. File: \Boot\BCD Status: 0xc0000098 Info: The windows boot configuration data file does not contain a valid OS entry. This began after the PC forced me to run a system recovery. My machine had powered down improperly (power outage?) and simply would not respond to my keyboard input to cancel the option to scan my system. After the scan "repaired" a boot file, my system crashed. Now it tells me I can insert my windows 7 disk and run recovery. I can't simply do this because of Safeguard. The system recovery can't see my encrypted drive. I tried hitting F2 to manually login to Safeguard and then selected the option to boot from media. The computer prompts me to hit any key to boot from disk...which I do, but once again it is not reading my keyboard input. I can't get F8/F6 to bypass startup files and get me to a command prompt like the old days. If I could get to a command prompt I might could recover the file windows jacked up from its backup location...though I may need to use the windows recovery disk UI to do this..??? In the past I've been able to slap in a PS/2 keyboard when the USB keyboards stop responding like this. I have no PS/2 keyboard available. Anyone have any idea how I can undo the damage windows system recovery has done with safeguard installed?

  • _default_ VirtualHost overlap on port 443, the first has precedence

    - by Mohit Jain
    I have two ruby on rails 3 applications running on same server, (ubuntu 10.04), both with SSL.

If you plan to use name-based virtual hosts, remember that they only work with your non-secure Web server. But not able to figure out how to run two ssl application on same server.

  • Where do vendors publish internal transfer rates of HDDs?

    - by red888
    So I've started to dig into storage fundamentals and found that in order to calculate the IOPS of a HDD you need to know the internal transfer rate of the drive (time it takes data to move from the platters to internal disk's cache). I went on newegg and even a few vendor sites and could not find this info published for any HDDs. Is it sometimes called something else? Take this link to a seagate HDD for instance. Nowhere do I see "internal transfer rate", but I do see something called "Sustained Data Rate OD"- is that the same thing? Just so you know where I'm getting this info (Book: "Information Storage and Management Storing, Managing..."): Consider an example with the following specifications provided for a disk: The average seek time is 5 ms in a random I/O environment; therefore, T = 5 ms. Disk rotation speed of 15,000 revolutions per minute or 250 revolutions per second — from which rotational latency (L) can be determined, which is one-half of the time taken for a full rotation or L = (0.5/250 rps expressed in ms). 40 MB/s internal data transfer rate, from which the internal transfer time (X) is derived based on the block size of the I/O — for example, an I/O with a block size of 32 KB; therefore X = 32 KB/40 MB. Consequently, the time taken by the I/O controller to serve an I/O of block size 32 KB is (TS) = 5 ms + (0.5/250) + 32 KB/40 MB = 7.8 ms. Therefore, the maximum number of I/Os serviced per second or IOPS is (1/TS) = 1/(7.8 × 10^-3) = 128 IOPS.

  • Spotlight has stopped indexing/returning anything in /Applications

    - by pra
    After a recent kernel panic & restart, Spotlight no longer seems to know anything about the files under my /Applications folder. I used to launch Safari.app, Opera.app, Textedit.app, etc via Spotlight as a matter of routine. Now, I get "No results found" for all of them (except Textedit.app, which launches a demo text editor from a Qt installation). The programs are still there & still launch directly from Finder. I've already run disk utility & verified the disk, no issues. I repaired disk permissions, which made several changes, but to no effect. Is there anything else I can do, short of re-installing MacOS? Update: I already verified that "Applications" was still checked in my Spotlight preferences. It was still returning applications located elsewhere (the Qt textedit sample app), so that shouldn't have been the issue. A few hours later it resolved itself; I guess there's a background process running on some interval.

  • Grub error 18, gparted not showing anything

    - by Montecristo
    Some week ago I started having some problems with my pc, sometimes it just freezed not allowing me to do anything. I had to turn it off and on and sometimes do it a couple of time even at startup. Now it does not start at all, grub is giving me error 18. I have found that a solution is to create a bootable partition in the first sector of the disk. gparted does not recognize any partition, the window in which there would be my partitions is empty. sudo fdisk -l does not output anything. If I type sudo mount /dev/sda and then tab tab to autocomplete these are the devices coming out: sda sda1 sda2 sda5. If I launch sudo mount -t ext3 /dev/sda1 disk I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg outputs [ 1831.974847] EXT3-fs: unable to read superblock Do you know how to solve this issue? I'm not completely sure this is a software problem, should I try with a new hard disk?

  • I need a reverse proxy solution for SSH

    - by Bond
    Hi here is a situation I have a server in a corporate data center for a project. I have an SSH access to this machine at port 22.There are some virtual machines running on this server and then at the back of every thing many other Operating systems are working. Now Since I am behind the data centers firewall my supervisor asked me if I can do some thing by which I can give many people on Internet access to these virtual machines directly. I know if I were allowed to get traffic on port other than 22 then I can do a port forwarding. But since I am not allowed this so what can be a solution in this case. The people who would like to connect might be complete idiots.Who may be happy just by opening putty at their machines or may be even filezilla.I have configured an Apache Reverse Proxy for redirecting the Internet traffic to the virtual machines on these hosts.But I am not clear as for SSH what can I do.So is there some thing equivalent to an Apache Reverse Proxy which can do similar work for SSH in this situation. I do not have firewall in my hands or any port other than 22 open and in fact even if I request they wont allow to open.2 times SSH is not some thing that my supervisor wants.

  • How can I remove all drivers and other files related to a USB Mass Storage device?

    - by Bob
    I have a flash drive here that does not work on one OS on computer - let's call it the desktop Windows 7. It works fine on another computer - laptop Windows 7. It also works fine on Windows 8 on the same desktop computer. Other flash drives work fine under desktop Windows 7. So not a hardware issue, not a generic USB Mass Storage driver issue. It's something specific to this drive. On desktop Windows 7, I can connect the drive but no volume comes up under Windows Explorer. Ditto for Disk Management. With diskpart, loading hangs until I unplug the drive, if I replug it and try list disk it hangs again. If I unplug the drive at this point, list disk prints out all attached drives - including the just removed flash drive. The drive consistently appears under Device Manager, but uninstalling the drivers, restarting and reinstalling the drivers (by inserting the drive) only works for the first insertion. After that it fails again. I get the feeling that the driver files are not actually removed, and are corrupted, meaning every reinstall it's the same corrupted drivers being installed. Is there any way to remove these drivers completely? Or perhaps some other setting Windows 7 retains? Formatting the drive through another computer/OS does not help. I've also tried a complete wipe and rebuild of the MBR and single partition. The allocation unit size makes no difference; neither does a NTFS format. This is a relatively small matter, and I would not like to reinstall the entire OS!

  • Are these three brand new sticks of RAM really dead?

    - by David Brown
    I'm working on a Dell Dimension 4700 desktop for a friend. It came with 512MB of DDR2 RAM (two sticks of 256MB). One morning, it started blue screening on startup with no helpful error messages. It refused to boot into any form of Windows installation, including Safe Mode, original recovery disk, and my custom Windows PE disk. It did boot into the Ultimate Boot CD, so I ran memtest86, which reported errors everywhere. I removed one stick of RAM and the system booted up just fine. I moved the remaining stick into each slot and the system continued to operate normally, so I came to the conclusion that the stick that I removed was dead. I ordered an exact replacement, along with 2 more sticks of 256MB DDR2 (again, exactly the same as the original), bringing the total system memory to 1GB. Upon installing the three brand new sticks, the system blue screened again, this time stating that win32k.sys attempted to write to read-only memory. I inserted my custom Windows PE disk in order to get a better look at the memory dump with BlueScreenView, but it refused to boot and produced another blue screen, but without an error message. I removed each new stick one-by-one, restarting each time. It continued to blue screen until I was left with only the original stick. I then tried inserting the new sticks in various different orders, but this only produced more blue screens. I reinserted all three sticks (along with the original) and ran memtest86 again, which reported errors all over the place. So, now I'm right back where I started. I don't think it could be the slots themselves, because I can plug the original stick into any slot and it works just fine. System setup reports each stick correctly and shows the total as 1GB, however. It just seems strange to me that all three brand new sticks of RAM could be dead on arrival. Is there something I missed? Or should I just go ahead and RMA them?

  • Hyper-V with multiple physical networks

    - by Yaman
    I have Hyper-V on my laptop with a wireless and Ethernet card, sometimes I connect using wireless card, and sometimes using the Ethernet cable. I am trying to configure Hyper-v to work always with internet provided to virtual machine. I have tried to create 2 virtual switches, one external to the Wireless network card, and the other one external to the Ethernet card. What happens is that the wireless network creates a bridge object in the network and sharing center\Network connections of windows 8, while the Ethernet does not. Unfortunately, they do not work together as external, i have to set the connected one to external and the other one as external, I also have to go to the properties of the bridge and virtual Ethernet properties to uncheck and check some components like: Client for Microsoft Networks Deterministic Network Enhancer VMWare Bridge Protocol QoS Packet Scheduler File and Printer Sharing for Microsoft Networks In order to make things work. Sometimes I keep the wireless network switch external, and go to another location (another wireless network), and it disconnects, i have to reconfigure the switches. Is there a way to do the configuration once and remain working wherever I connect, whether its Wireless or Ethernet and on any network with DHCP?

  • Installing Ubuntu guest crashes Hyper-V host

    - by Grant
    I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system! My setup is: Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM Dell MD3600f SAN Server 2008 R2 Datacenter System Center VMM 2012 There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up. It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected. The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change. There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting. What could cause the host machine to freeze like that? It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!

  • Can MySQL use multiple data directories on different physical storage devices

    - by sirlark
    I am running MySQL with its data dir on a 128Gb SSD. I am dealing with large datasets (~20Gb) that are loaded and processed weekly, each stored in a separate DB for the purposes of time point comparisons. Putting all the data into a single database in unfeasible because the performance on such large databases is already a problem. However, I cannot keep more than 6 datasets on the SSD at a time. Right now I am manually dumping the oldest to much larger 2Tb spinning disk every week, and dropping the database to make space for the new one. But if I need one of the 'archived' databases (a semi regular occurrence) I have to drop a current one (after dumping), reload it, do what I need to, then reverse the results. Is there a way to configure MySQL to use multiple data directories, say one on the SSD and one on the 2Tb spinning disk, and 'merge' them transparently? If I could do this, then archiving would no longer mean "moved out of the database entirely", but instead would mean "moved onto the slow physical device". The time taken to do my queries on a spinning disk would be less than that taken to completely dump, drop, load, drop, reload two entire databases, so this is a win. I thought of using something like unionfs but I can't think of a way to control which database gets stored on which physical drive, because it works by merging on a directory level (from what I understand) so I'm still stuck with using multiple directories. Any help appreciated, thanks in advance

Now, I get "No results found" for all of them (except Textedit.app, which launches a demo text editor from a Qt installation). The programs are still there & still launch directly from Finder. I've already run disk utility & verified the disk, no issues. I repaired disk permissions, which made several changes, but to no effect. Is there anything else I can do, short of re-installing MacOS? Update: I already verified that "Applications" was still checked in my Spotlight preferences. It was still returning applications located elsewhere (the Qt textedit sample app), so that shouldn't have been the issue. A few hours later it resolved itself; I guess there's a background process running on some interval.

  • F5 BIG_IP persistence iRules applied but not affecting selected member

    - by zoli
    I have a virtual server. I have 2 iRules (see below) assigned to it as resources. From the server log it looks like that the rules are running and they select the correct member from the pool after persisting the session (as far as I can tell based on my log messages), but the requests are ultimately directed to somewhere else. Here's how both rules look like: when HTTP_RESPONSE { set sessionId [HTTP::header X-SessionId] if {$sessionId ne ""} { persist add uie $sessionId 3600 log local0.debug "Session persisted: <$sessionId> to <[persist lookup uie $sessionId]>" } } when HTTP_REQUEST { set sessionId [findstr [HTTP::path] "/session/" 9 /] if {$sessionId ne ""} { persist uie $sessionId set persistValue [persist lookup uie $sessionId] log local0.debug "Found persistence key <$sessionId> : <$persistValue>" } } According to the log messages from the rules, the proper balancer members are selected. Note: the two rules can not conflict, they are looking for different things in the path. Those two things never appear in the same path. Notes about the server: * The default load balancing method is RR. * There is no persistence profile assigned to the virtual server. I'm wondering if this should be adequate to enable the persistence, or alternatively, do I have to combine the 2 rules and create a persistence profile with them for the virtual server? Or is there something else that I have missed?

  • GRUB having problems with my sda1 UUID

    - by Igoru
    I was having trouble trying to setup triple boot on my computer... (Take a look at this thread if you think it would help). I ended up by having a GRUB menu that has Ubuntu entries and "Windows" entry, that calls an EasyBCD menu to choose between Windows 7 and XP. Everything would be fine if, only if, GRUB was set up correctly. I can't find why, but it throws me this when I try to open Ubuntu: I've already tried to remove the menu.lst and do a grub-update, and a grub-install too. I tried to create a symlink to /dev/sda1 at /dev/disk/by-uuid/<<uuid that is there>>, just like the other UUIDs that were there... But I couldn't find that symlink at that busybox that opened when it thrown me the error. Any ideas? [UPDATE] This is the GRUB entry with problems: title Ubuntu 9.04, kernel 2.6.28-15-generic uuid b1ed36e5-4d84-4eb8-86ef-6f1135ffc238 kernel /boot/vmlinuz-2.6.28-15-generic root=UUID=b1ed36e5-4d84-4eb8-86ef-6f1135ffc238 ro quiet splash initrd /boot/initrd.img-2.6.28-15-generic quiet And this my /dev/disk/by-uuid folder: 04DCBCFBDCBCE856 - ../../sdb1 (NTFS backup disk) 4434E77734E769FE - ../../sda4 (NTFS WinXP) ACB09F0DB09EDCE0 - ../../sda2 (NTFS Win7) b5311be8-a853-4fdd-aed5-d65974b3c0c4 - ../../sda5 (EXT4 home) C04B-4D97 - ../../sdc (FAT32 live-pendrive from which i'm running) D28447F68447DB9B - ../../sda6 (NTFS files partition) e0e88f38-d815-423a-9d5e-64b9c74a8b92 - ../../sda7 (swap)

  • How do I cancel windows server 2003 repair install?

    - by Kilgore2k
    System: Windows 2003 Server Enterprise Scenario: NTDS db is corrupt and all attempts to fix with esentutl fail. Ran chkdsk which seemed to repair disk error and give access to the ntds.dit file but still esentutl fails. (Attached the drive to a different server to run the esentutl) Error: Access to source database '[path to copy of]/ntds.dit' failed with Jet error -1022. Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.170 seconds. This error occurs on any disk I cpoy the files to including original location in C:\WINDOWS\NTDS\ Now enter the "Stupid!" and "what was I thinking!?" part (must be the late hour...) Stupid: No updated backup - after using a backup I get a network password error in the lsass error. what was I thinking!?: Started the install repair from the original CD but the install fails since the AD fails to start. Now I cant boot into any mode (safe mode, AD restore etc) nor complete the repair install. I would really like to avoid a fresh install since I have the Exchange server on this DC and would rather migrate to a new server than have to start from scratch. Thanks!

  • "Dictionary problem." Error with VMPlayer

    - by George Mauer
    I'm pretty new to using vmware virtualization (been a virtualbox user) so I'm hoping you guys can help me out. I recently got an external usb disk containing a vm for a client, downloaded vmplayer, set it up with "Open a Virtual Machine", ran it, easy as pie. After working with it a bit this morning, I shut the VM down and now trying to start it back up again I get this: I tried removing the vm from my library, now it happens whenever I try to add it back in. In the meantime, I can still access other virtual machines so it seems like the problem might be with the virtual disk. So two questions: This is obviously not a very helpful error message. Where can I go to get more information? My Application EventLog doesn't contain anything from VMWare. What steps can I take to fix the problem? Edit: A couple more pieces of information. I did not take any snapshots. I don't think VM Player even has that ability. I have a zip file of (what I assume) is the state of the VM when it was sent to me. I cannot unzip it as it is huge and simply requires more HD space than I have available but I did extract the vmx file and examine it. Other than the UUIDs and the fact that mine reads cleanShutdown = "FALSE" they are identical. The log contains the following lines Jun 23 10:11:18.080: vmx| SNAPSHOT: SnapshotConfigInfoRead: Unable to load dict from 'E:....\MachineName.vmsd'. Jun 23 10:11:18.080: vmx| SNAPSHOT: SnapshotConfigInfoRead failed for file 'E:....\MachineName.vmx': Dictionary problem (6) Jun 23 10:11:18.082: vmx| SNAPSHOT: Snapshot_TimeStampTiers failed: Dictionary problem (6)

  • Ubuntu 12.04 partioning an external drive without lossing data

    - by Menelaos Perdikeas
    I have an Ubuntu 12.04 with an external 1.5T disk (just for data). It is /dev/sdc1 seen below: $ df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda1 ext4 1451144932 27722584 1350794536 3% / udev devtmpfs 6199460 4 6199456 1% /dev tmpfs tmpfs 2482692 988 2481704 1% /run none tmpfs 5120 0 5120 0% /run/lock none tmpfs 6206724 284 6206440 1% /run/shm /dev/sdc1 fuseblk 1465135100 172507664 1292627436 12% /media/Elements The thing is I would like to implement this rsync-based backup strategy and I want to use my /dev/sdc1 external drive for that. Since the guide mentioned above recommends placing the backup directory in a separate partition I want to repartition the /dev/sdc1 external hard disk but retain existing data in a separate partition. E.g. split /dev/sdc1 into two partitions: (i) one to be used exclusively for the rsync-based backup and (ii) the other for the existing miscellaneous data. How should I go about partitioning with minimal risk to my existing data and what kind of filesystem do you recommend? I would prefer a console-based guide but unfortunately all the material I found on the web is oriented towards partitioning the main (bootable) disk and not an external fuseblk filesystem used only for passive data.

  • In Windows 7 power management, is it possible to set different sleep settings for different SATA disks?

    - by Ben Voigt
    I'm having an issue with Windows 7 either freezing up or generating a BSOD coming out of sleep. I suspect that it is related to my boot/OS drive, an OCZ Vertex SE SSD, because numerous other Vertex users have reported sleep problems. Notably, if I put the computer to sleep, it almost always wakes correctly. If it goes to sleep after a timeout, it almost always BSODs. I disabled timed sleep and now it freezes when left unattended. My next step is to disable "Put hard disks to sleep after X minutes", but I'd like to change this setting only for the SSD and not for the rotating data disks, which I would like to spin down normally. Does anyone know a place to configure sleep on a per-disk basis? I don't need to set different timeouts on different disks (although that would be nice), simply setting "this disk sleeps" and "sleep is disabled for this disk" would be great. Additional system information: Windows 7 Ultimate x64, Core i5 - P55 chipset, Intel RST drivers are installed. One SSD, two rotating HDD, and a DVD-RW drive are all connected to the Intel SATA ports. I could potentially move some of these to my motherboard's other SATA controller if that would help.

  • The best way to hide data Encryption,Connection,Hardware

    - by Tico Raaphorst
    So to say, if i have a VPS which i own now, and i wanted to make the most secure and stable system that i can make. How would i do that? Just to try: I installed debian 7 with LVM Encryption via installation: You get the 2 partitions a /boot and a encrypted partition. When booting you will be prompted to fill in the password to unlock the encryption of the encrypted partition, Which then will have more partitions like /home /usr and swapspace which will automatically mount. Now, i do need to fill in the password over a VNC-SSL connection via the control panel website of the VPS hoster, so they can see my disk encryption password if they wanted to, they have the option if they wanted to look at what i have as data right? Data encryption on VPS , Is it possible to have a 100% secure virtual private server? So lets say i have my server and it is sitting well locked next to me, with the following examples covered bios (you have to replace bios) raid (you have to unlock raid-config) disk (you have to unlock disk encryption) filelike-zip-tar (files are stored in encrypted archives) which are in some other crypted file mounted as partition (archives mounted as partitions) all on the same system So it will be slow but it would be extremely difficult to crack the encryption. So to say if you stole the server. Then i only need to make the connection like ssh safer with single use passwords, block all incoming and outgoing connections but give one "exception" for myself. And maybe one for if i somehow lose my identity for the "exeption" What other overkill but realistic security options are available, i have heard about SElinux?

  • Is there an objective way to measure slowness of PC/WINDOWS?

    - by ekms
    We've a lot of users that usually complain about that his PC is "slow". (we use win XP). We usually check startup programs, virus, fragmentation, disk health and common problems that causes slowness (Symantec AV drops disk to 1mb/s , or a seagate HD firmware error in certain models), but in those cases the slowness is pretty evident. In other hand, the most common is the user complaining about his pc but for us looks OK, even in 6 years old desktops. People sometimes even complains about his new quad core desktops speed!!! So, we are asking if there's a way to OBJECTIVELY check that a computer didn't dropped its performance, compared with similar ones o previous measures, specially for work use (I don't think that 3dmark benchmark o similar may help). The only thing that I found that was useful is HDTune, but it only check hard disk performance. Basically, what we want is something that enable us to say to our users "see? your PC is as slow as was three years ago! stop complaining! Is all in your head!"
