  • Logfiles filling with iptables logging

    - by Peter I
    OS: Debian 6 Server Version I have different logfiles which are filling up: user@server:/var/log$ ls -lahS | head total 427G -rw-r--r-- 1 root root 267G Nov 2 17:29 bandwidth -rw-r----- 1 root adm 44G Nov 2 17:29 kern.log -rw-r----- 1 root adm 27G Nov 2 17:29 debug -rw-r----- 1 root adm 23G Oct 27 06:33 kern.log.1 -rw-r----- 1 root adm 17G Nov 2 17:29 messages -rw-r----- 1 root adm 14G Oct 27 06:33 debug.1 -rw-r----- 1 root adm 12G Nov 2 17:29 syslog -rw-r----- 1 root adm 12G Nov 1 06:26 syslog.1 -rw-r----- 1 root adm 9.0G Oct 27 06:33 messages.1 So I looked up the file /etc/iptables.up.rules which had those lines in it: -A FORWARD -o eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_OUT: -A FORWARD -i eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_IN: -A OUTPUT -o eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_OUT: -A INPUT -i eth0 -j LOG --log-level 7 --log-prefix BANDWIDTH_IN: So deleting those lines will solve my problem. But how would I edit those lines without losing their functionality?

  • DEBIAN-likes to detect the keyboard layout

    - by blietaer
    I would like to find out the current keyboard layout of a debian-like OS. env-var? /etc/? locales? Context: __ Playing around with RFID reader in serial, using python to output to console through uinput/ The thing is, doing the conversion from fake-rfid-keyboard-codes to code sent to uinput/, I would better know if I am using a QWERTY or an AZERTY ('a' becoming 'q', etc...) Back here in Belgium, especially during the event I am working on we are highly susceptible to have both keyboard layouts, I have to support both 'on-the-fly' __ Thanx !

  • How do I mount a CIFS share via FSTAB and give full RW to Guest

    - by Kendor
    I want to create a Public folder that has full RW access. The problem with my configuration is that Windows users have no issues as guests (they can RW and Delete), my Ubuntu client can't do the same. We can only write and read, but not create or delete. Here is the my smb.conf from my server: [global] workgroup = WORKGROUP netbios name = FILESERVER server string = TurnKey FileServer os level = 20 security = user map to guest = Bad Password passdb backend = tdbsam null passwords = yes admin users = root encrypt passwords = true obey pam restrictions = yes pam password change = yes unix password sync = yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . add user script = /usr/sbin/useradd -m '%u' -g users -G users delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' guest account = nobody syslog = 0 log file = /var/log/samba/samba.log max log size = 1000 wins support = yes dns proxy = no socket options = TCP_NODELAY panic action = /usr/share/samba/panic-action %d [homes] comment = Home Directory browseable = no read only = no valid users = %S [storage] create mask = 0777 directory mask = 0777 browseable = yes comment = Public Share writeable = yes public = yes path = /srv/storage The following FSTAB entry doesn't yield full R/W access to the share. //192.168.0.5/storage /media/myname/TK-Public/ cifs rw 0 0 This doesn't work either //192.168.0.5/storage /media/myname/TK-Public/ cifs rw,guest,iocharset=utf8,file_mode=0777,dir_mode=0777,noperm 0 0 Using the following location in Nemo/Nautilus w/o the Share being mounted does work: smb://192.168.0.5/storage/ Extra info. I just noticed that if I copy a file to the share after mounting, my Ubuntu client immediately make "nobody" be the owner, and the group "no group" has read and write, with everyone else as read-only. What am I doing wrong?

  • Accessing a shared folder using other credentials with Windows 7

    - by Nicolas Buduroi
    I was at a client office trying to connect to a shared drive on their network but was greeted by a "you do not have permission to access" error! Couldn't find any way to enter the required credentials as this message didn't had any other options. Tried to map the drive, selected the option to enter the correct credentials (with \\HOST\user) but it wouldn't work at all. The worst thing in all of this is that my coworker who is using OS X has been able to connect to that drive without any problem, he clicked on it, entered the credentials and could open the folder! The folder is shared by a Windows Small Business Server 2008 machine.

  • Outlook 2007 disconnecting after sending email to specific email

    - by Michael
    So when a user emails another tech in my domain they get the prompt for username/password as though they got disconnected. I have not seen any issues in the event logs, tried deleting the email address from his auto correct, ran Outlook in safe mode and searched online as well. I am kind of lost. Checked the event logs on the exchange server as well in the security and still nothing. Exchange 2010, Client OS: Vista x64, Outlook 2007. Thanks!

  • Running Ubuntu Server from a USB key / thumb drive (being mindful of flash's write limitations)

    - by andybjackson
    Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and a ZFS RAID-Z array for data. I settled on this configuration after trying and regretfully rejecting FreeNAS because the Logitech Media Server (LMS) software isn't available on the AMD64 flavour of this platform and because I think Debian/Ubuntu server is a better future-proof platform. I considered Open Media Vault, but concluded that it isn't quite yet ready for my purposes. That said, FreeNAS does include the option to run itself off a 2GB+ flash device like USB key or thumb drive. Apparently FreeNAS is mindful of the write limitations of flash devices and so creates virtual disks for running the OS, writing only the required configuration information back to flash. This would give me an extra data drive slot. Q: Can Ubuntu Server be configured sensibly to run off a flash device such as a USB key/thumb drive? If so, how? The write limitations of flash should be accounted for.

  • What Does Installing Ubuntu "Alongside" Windows Entail?

    - by Soft Skeleton
    I recently posted a question about an error I was receiving trying to access Ubuntu from the boot menu. I am using Windows 7 and Ubuntu 12.x (I THINK because I haven't accessed it in over a year due to being unable to run an important program for one of my classes on Ubuntu). On another laptop, I partitioned the hard drive and installed Windows and Ubuntu on the partitions. On this laptop, I simply installed Ubuntu from Windows, picking the option "alongside Windows", and didn't partition my hard drive manually. I was under the impression "alongside" entailed that Ubuntu would partition my hard drive, and that if I were to return my Windows partition to factory settings it would not affect the Ubuntu partition. However, given my current problem, I am wondering if I was mistaken in this assumption? When installing Ubuntu from Windows, selecting "alongside" Windows as the option from the Ubuntu installer, does that simply install Ubuntu within the Windows partition and thus returning it to factory settings would wipe out anything I had on the Ubuntu OS as well? Ubuntu is still in the boot menu as an option, but when I try to access it it says the drive is "corrupt" and wubi is mentioned in the error. I additionally tried to download a program ran from Windows to investigate partitions and there were no sign of my Ubuntu partition viewable from Windows. Is it possible Windows just can't see it? Any insight, corrections or answers is appreciated.

  • Which Linux variant to install on VirtualBox?

    - by Rohit
    Answer to one of my previous post suggested me to use VirtualBox for Sandbox experiments with malware files. I installed VirtualBox and now it demands a bootable CD to install the OS. I want Linux to be installed in it. I guess Debian or Ubuntu are the most popular variant. I want an ISO image that creates a bootable CD or a single DVD with that Linux variant and should include only the basic installation not much features. It should fit in at least 3 or 3.5 GB. Which one is more compatible with VirtualBox?

  • How to restore one contact from Address Book with Time Machine

    - by doekman
    I want to restore one contact from my Address Book with Time Machine. To do so, I select the contact in Address Book. Then, I press the Time Machine icon in the dock. Then my address book is "taken into space". However, when I browse back in time (either pressing the arrow back, or selecting a time on the right), the contact details do not change. And I am sure the data has been changed between dates. Also, when I do press restore, it's still the new data, not the backup. Is this a bug, or am I doing something wrong? I'm using OS X 10.6.3 in combination with a external USB drive on an iMac.

  • Netbook Remix 10.04 to 10.10 upgrade using alternate iso

    - by Suman Subramonian
    I'm using Netbook Remix 10.04 now. I'm having the 10.10 alternate iso with me. If I use that iso to upgrade, will I lose my netbook version? I've seen in some forums that the upgrade resulted in a change from netbook version to desktop version. Updated on 15/12/2010 I upgraded the OS from 10.04 to 10.10. But I'm getting an error like this after restart: modprobe: FATAL: Could not load /lib/modules/2.6.35-22-generic/modules.dep: No such file or directory I searched in the forums and got a solution like this: Open Terminal gksudo gedit /etc/initramfs-tools/initramfs.conf change the line MODULES=most to MODULES=dep Then use Synaptic (SystemAdministrationSynaptic Package Manager) to reinstall initramfs-tools. I'll be definitely trying this later. After that when the system tries to login, my screen starts flashing with just the ubuntu netbook desktop wallpaper on the screen. No other options will be available. It will be flashing continuosly. If I press the power button then one window comes up with options like Shut down, Restart, Hibernate etc. And the screen won't stop flashing either. I've uploaded a 1 min video. Please go through it as it will give you a clear idea of the error which I'm facing now Video Link Here

  • Challenging Job after Graduate Studies

    - by sriram
    I worked with an M.N.C developing web applications in Java/J2EE related technologies(includes JSF,struts,hibernate etc.) now I quit my job to pursue Graduate Studies in the U.S.A. So I am a student in the middle of my Graduate studies. I had enough of developing mere CRUD applications in J2EE now I want to work in something exciting. The problem is I can't say what exactly but I can give you an examples. Say developing new JDK libraries or writing a kernel for some O.S. or something like that. So I have five questions here. Is it true that people in R & D often use C++ because of higher performance in that case should I consider switching my platform to C/C++? How should I use my time I have one year to graduate to prepare myself for Jobs Interviews for such positions? (e.g. Reading books on Algorithms etc.) How do I know about these jobs and how do I apply to those Jobs? Is it the right time for me to think about Jobs? Am I over ambitious because I am not in a Ivy League, just a normal school? (My GPA is not so high unfortunately).

  • Alerting when a RAID Array disk fails locally on VMWare ESX or ESXi System

    - by Tim K
    With ESX and ESXi, we recently had two systems where that the boot partition became degraded due to a failed disk. The only alert we managed to capture was the visual alert on the Dell servers. We failed to received any electronic alerts regarding the failed or degraded array. Does anyone have any experience with monitoring for these types of failures? In both cases, the servers were running in a RAID 5 SCSI configuration (5 disks on one system, 3 disks on another) which if we were running a Windows Server OS, we would have had an alert created in the Eventviewer. Where would I begin to look for this solution. Can it be configured in VCenter or vFoglight?

  • KVM to Xen migration

    - by qweet
    I've recently been appointed to create some VMs for production use, and went gung ho into making a KVM based VM instead of finding out what our production server uses. I've only recently found out though that our own servers use Xensource OS, and don't look like they're going to be upgraded in the near future. So for the moment, I'm stuck with either two choices- attempting to convert the KVM VM into a Xen VM, or rebuilding what I have into a new Xen VM. Being the lazy person I am, I would rather not have to rebuild the VM. I've looked for some documentation on a procedure to do this, but the only thing I can come up with is an ancient article with some vague instructions. So this is my question, Server Fault- can one migrate a KVM running on a KVM kernel to a Xen kernel? And if so, how?

  • Which file system to choose from when formatting 1.5TB hard drive (hdd)

    - by MaxiWheat
    I plan to buy a 1.5TB hard drive soon. I would like to know which file system to choose from when I'm gonna format it. With FAT32, there is a limitation concerning the maximum file size (4GB) that bugs me since I might save large files such as DVD images which are over 4GB. On the other hand, NTFS allows me to save larger files, but seems less compatible with other OS than Windows and is also proprietary to Microsoft. Are there other alternatives ? Can you give me your advices ?

  • How do I kill a process that keeps respawning?

    - by terabytest
    I got infected by a virus. It looks like I removed it, but it somehow injected a few more processes (I can see them in the task manager) that respawn when I kill them (somehow). Is there a way to destroy those process to stop them from respawning, or in the case something else is respawning them, to kill that "something"? I really don't want to format my pc for this. The data in it is very important for me (personal value) so I'd really want to know a way to do this without reinstalling my OS. I'm on Windows Vista 32 bits.

  • What would be a good topic for research on "edge of multiple processors / computers programming" topic?

    - by Kabumbus
    This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

  • Toggle "ask for password after screensaver/sleep" or the delay in 10.7 using terminal

    - by desbo
    There's an option in the preference panel to change the time the mac is able to be in sleep/screensaver before requiring a password to be unlocked again. I'm using OS X Lion 10.7. Is there any way to change this setting using the terminal or an applescript? I tried to change the plist file using: defaults write com.apple.screensaver askForPasswordDelay -int 60 also tried defaults write com.apple.screensaver askForPasswordDelay -float 60 also completely disabling the password didnt work either defaults write com.apple.screensaver askForPassword -int 0 The plist file was changed, but it had no effects at all. It's the same plist file that gets changed when manually switching the setting in the preferences. Would be awesome if anyone got an idea how to fix my problem. EDIT: also tried to: 1) add -currentHost flag 2) drop the -int / -float

  • what can I do with an old but working PC [closed]

    - by fskreuz
    I have an old Dell optiplex GX240 on Pentium 4 1.8Ghz and 256MB Ram (or was it 512MB). It's still in working condition but it's getting slow for me and i wanted to optimize it. I just want that old box to be usable even for simple desktop use (email, surfing, chat). I also have to note that my parents prefer use it over a laptop for some reason. Treat it as a "box-type netbook". unlike the other threads that they all prefer sending away or use as file server, firewall and that, i am looking for suggestions on how to keep it usable as the main PC. any suggestions? OS perhaps?

  • How can I copy the output from a remote command into the local clipboard?

    - by cwd
    I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.

  • Is it possible to run an Automator workflow when a USB device is connected?

    - by pkaeding
    I would like to run an Automator workflow every time I connect a certain thumbdrive to my OS X Snow Leopard system. This workflow will copy certain files from my hard drive onto the thumb drive. I have the workflow part figured out, but I don't know how to trigger it. Ideally, I wouldn't need to do anything; it would run as soon as the drive is mounted. Is this possible? Am I approaching this from the wrong angle? The solution only really needs to work on Snow Leopard. Thanks!

  • windows 2000 freezing during large disk write

    - by robert
    We have a windows 2000 sp4 server which freezes up for about 1 minutes while its web-app does a ~500mb write operation. I can see the webapp start to do I/O activity (through process explorer) then the RDP session becomes unresponsive, you can click on windows and buttons but nothing happens. When the disk write finally finishes the session 'catches up' on all the mouse clicks you did during the freeze in a mad flurry of window activity and the server returns to normal. During the freeze the web-app stops as well. The same behaviour happens on the console of the server. (so I know its not a network thing) Nothing appears in the Event logs. Its like nothing happened. I have upgraded all the HP hardware drivers to the latest proliant support pack. And also run a HP hardware diagnostics which found nothing wrong. What would cause a disk write to lock the rest of the OS?

  • How come Win+R prompt can open Python when it's not in my path?

    - by houbysoft
    When I use the run prompt in Windows XP Professional (Win+R), and type python.exe or python, it works and greets me with the python prompt. However, when I start a cmd window, and then type python.exe or python, it doesn't find it. This is what I expect, as the Python directory (for me, I:\Python31\) is not in my PATH. How come, then, that if I type python.exe in the Win+R prompt, it works? Edit: here is a partial output of SET, I removed most irrelevant entries, I'm not sure why is it useful, apart from the PATH variable which I already said doesn't include the Python directory. If you need a particular variable other than these, please ask. CLIENTNAME=Console CommonProgramFiles=I:\Program Files\Common Files ComSpec=I:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO OS=Windows_NT Path=I:\WINDOWS\system32;I:\WINDOWS;I:\WINDOWS\system32\WBEM;I:\WINDOWS\system32\WindowsPowerShell\v1.0;I:\Qt\2010.05\mingw\bin;I:\Program Files\CMake 2.8\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PSC1 ProgramFiles=I:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=I: SystemRoot=I:\WINDOWS VBOX_INSTALL_PATH=I:\Program Files\Oracle\VirtualBox\ windir=I:\WINDOWS

  • Booting a GPT USB key on older BIOS laptop

    - by fonix232
    I have an old HP EliteBook 8530p, which does not support booting from GPT USB (GPT HDDs are fine though). Lately I had the wish to have a fast-to-start OS for browsing, smaller web tasks, etc., so I grabbed a ChromeOS build (latest one by ArnoldTheBat), flashed it on an 8GB flash drive, and popped it in. It did not boot, so I dug deeper and discovered that it actually is GPT, and cannot be converted to MBR. As my laptop does not support UEFI booting from USB (there's a really-really beta UEFI support in the BIOS, but as I said, it only supports GPT hard drives, not USB devices), I'm stuck. Is there any way of booting it, say, another flash drive with a specific boot loader/manager (e.g. Plop)?

  • Native AAA games coming to Ubuntu. Where they will be installed?

    - by user86274
    Many users use SSD disks (and I believe many more in the future) for their OS. 128GB SSD disks are common place nowadays and many users (like me) use their SSD for dual booting (Windows and Ubuntu). Ubuntu installations like this occupies 20-40 GB (/ , /home and swap). Up to now there was no problem. In a few weeks though, triple A games are coming to Ubuntu (i.e. l4d2) that require probably tens of GB for installation. In windows there is no problem, because you can install a game anywhere you want (i.e. I install games in D:/Games/). In Ubuntu, though, programs install files in many places (i.e. /usr/* , /lib, /etc ) so from what I remember, I never had the option to choose where to install a program. So, how will it be possible to install AAA games that require many GBs, when our Ubuntu installations won't have the necessary space? Could a /opt mounted on a mechanical disk (HDD) be the solution? Is it something I am missing?
