  • Kernel Log "TCP: Treason uncloaked!"

    - by hurikhan77
    On one linux server (Gentoo hardened), we are experiencing bursts of the following messages in dmesg from time to time: TCP: Treason uncloaked! Peer xx.xx.xxx.xxx:65039/80 shrinks window 4094157295:4094160199. Repaired. Is there anything we should take care of or is this normal? Update: Maybe related, we are using net.ipv4.tcp_congestion_control = cubic. Kernel version is 2.6.28 with Gentoo hardening patches.

  • Encrypting all outgoing email

    - by AliGibbs
    I have a client requirement to encrypt all outgoing email from a linux server. This can be done using any software, sendmail/postfix etc. They have given me the key they want to use, and want all forms (using php) to be encrpyted. Can I set sendmail/etc to encrypt all emails? This could be done with the same key for all mail. Thanks

  • Multiple IP stacks

    - by Aditya Sehgal
    I have a linux box with two ethernet interfaces (eth0 & eth1) with two corresponding IPs. As per my understanding, currently they are served by 1 IP stack. Is it possible to install another IP stack with IP Stack 1 handling ethernet interface eth0 and the other IP stack handling eth1.

  • Setting a non-standard proxy

    - by Julio Guerra
    I am behind a proxy which requires users to login during the first connection with a username and password with a HTML form. Thus, it is not handled with usual http://username:[email protected] and any attempt to access the internet from this setting falls into the login form. How could I automatically login to the proxy? In linux, what manages proxy stuffs when a command tries to access the internet? Thank you.

  • Latency in TCP/IP-over-Ethernet networks

    - by aix
    What resources (books, Web pages etc) exist out there that: explain the causes of latency in TCP/IP-over-Ethernet networks; mention tools for looking out for things that cause latency (e.g. certain entries in netstat -s); suggest ways to tweak the Linux TCP stack to reduce TCP latency (Nagle, socket buffers etc). The closest I am aware of is this document, but it's rather brief. Alternatively, you're welcome to answer the above questions directly.

  • How print multiple independent pages in one print job?

    - by C.W.Holeman II
    How can I combine multiple single page prints into a single print job? For example, using Firefox on Linux one can print a web page such that each sheet of paper has four pages printed upon it. I would like to combine several separate web pages so that for example, web-page-a, web-page-b and web-page-c (each less than one print page long) are printed on a single sheet of paper. I would like to do this without having to use some for of image editor to combine them.

  • What Are Some Good Open Source Alternatives to Active Directory?

    - by Laz
    I'm looking for a good open-source alternative to active directory that can handle: Authorization/Authentication Group Policy Replication and Trust Monitoring In addition, are there any consolidated systems out there that handle these responsibilities? Edit: Since a lot have asked for more details, I am trying to offer a service setting up an infrastructure for organizations, hardware/software setups, right now I am looking at a Linux stack, both desktops and servers, however a hybrid stack is possible, and I am investigating alternatives.

  • How to fix grub after moving root partition?

    - by Grzenio
    Hi, Because I am using one of the new WD disks I am trying to aling my root partition with the real sectors, as described here: http://community.wdc.com/t5/Desktop/Problem-with-WD-Advanced-Format-drive-in-LINUX-WD15EARS/m-p/10920#M631 So I copied all files to a temp location, deleted my partition (/dev/sda3), recreated it a few cylinders later (same name) and copied the files to the newly created partition. But now when I try to boot, I get my old grub menu but after selecting my kernel version it hangs... Any idea how I can fix it?

  • Operative systems on SD cards

    - by HisDudeness
    I was getting some wild ideas the last days, like putting some operative systems into SD cards rather than on my hard drive. I'll go further into details now and explain what lead me to consider this probably abominable decision. I am on a laptop (that means I have a native SD-card reader) which is currently running a cross-distro setup, with a bunch of Linux systems (placed in dedicated ext4 logical partitions into a huge extended one) regulated by an unique GRUB. Since today, my laptop haven't even seen any Windows system with binoculars. I was thinking about placing all the os part of my setup into a Secure Digital to save all my 500 Gb Hard Drive for documents, music, videos and so on, and being able to just remove the SD and boot my system into another computer too, as well as having the possibility of booting other systems into mine by just plugging in another SD, without having to keep it constantly placed in my PC. Also, in the remote case in the near future I just wanted to boot Windows 8 in it, I read it causes major boot incompatibility issues with other systems by needing a digital signature in order for them to start. By having it in a removable drive, I could just get rid of it when I'm needing him and switch its card with Linux one, and so not having any obstacles to their boot. Now, my questions are: I know unlikely traditional rotating disk drives, integrated circuits ones have a limited lifespan in terms of cluster rewriting. Is it an obstacle to that kind of usage? I mean, some Ultrabooks are using SSD now, is it the same issue, or there are some differences between Solid State Drives and Secure Digitals in that sense? Maybe having them to store system files which are in fixed positions (making the even-usage of cluster technology useless) constantly being re-read and updated and similar things just gets them soon unserviceable, do it? Second question: are all motherboards and BIOSes able to boot from SDs just like they are from USB pen drives (I mean, provided card reader is USB-connected, isn't it)? Or can't bootloaders like GRUB be installed on SDs working? If they can't, is it a solution installing GRUB to MBR and making boot option pointing to SD? Will it work? Are there any other problems to installing OSs on a Secure Digital?

  • Run VirtualBox in background, without a window

    - by Bashman
    Hi! I was wandering if it's possible to run an Ubuntu virtual machine using VirtualBox in background, I mean, without any window open. The idea is to conect via SSH to the linux host, that would be running in background. Have you ever done somenthing like this? Is it possible? Thanks!

  • Anyone know how to get dual screens working on a Dell E6410 laptop with Ubuntu 10.04 64 bit?

    - by Curtis
    I've installed the drivers from nVidia. When I go into the NVIDIA X Server Settings application, in the X Server Display Configuration setcion, and click the "Configure" button, "TwinView" is disabled. Also, clicking "Detect Displays" doesn't pick up my monitor (which is connected through a port replicator - keyboard and mouse in that port replicator work fine). Has anyone else seen this? Is this just a limitation of the current nvidia linux drivers?

  • Poor performance of single processor 32bit Windows XP xompared SMP in VBA+Excel

    - by Adam Ryczkowski
    Welcome! On many computers I experienced poor performance of 32 bit guests running on 64 bit Linux host (I used only the Debian family). At last I managed to collect benchmark data. I made the benchmark by running custom VBA macro, (which we use in our company) that generates 284 pages long Word document full of Excel Pie charts, tables and comments. The macro is run as a single task (excluding the standard services) on a set of identically configured Windows XP 32-bit systems. I measured the time (in sec.) needed to perform the test. The computer (i.e. my notebook Asus P53E) supports both VT-d extensions and native Windows XP. It has 2-core processor, each core is hyperthreaded, so in total we have 4 mostly independent execution units. I use the latest VirtualBox 4.2 and VMWare Workstation 9.0 for Linux, installed together on the same host (running Mint 13 Maya) but never run simultaneously. The results (in column Time) are no less accurate than ± 10% Here are the results (sorry for the format, but I couldn't find out a better solution for tables in SO): +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | Host software | # processor | Windows kernel | IO APIC | VT-x/AMD-V | 2D Video Accel | Time | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 0 | 1139 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 1 | 1 | 1050 | | VirtualBox | 1 | Advanced Configuration and Power Interface (ACPI) PC | 0 | 0 | 1 | 1644 | | VirtualBox | 4 | ACPI Multiprocessor PC | 1 | 1 | 1 | 6809 | | VMWare | 1 | ACPI Uniprocessor PC | | 1 | 1 | 1175 | | VMWare | 4 | ACPI Multiprocessor PC | | 1 | 1 | 3412 | | Native | 4 | ACPI Multiprocessor PC | | | | 1693 | | Native | 1 | Advanced Configuration and Power Interface (ACPI) PC | | | | 1170 | +---------------+-------------+------------------------------------------------------+---------+------------+----------------+------+ Here are the striking conclusions: Although I've read in the VirtualBox fora about abysmal performance with 32-bit guest on 64-bit host, VMWare also has problems compared to native run, still being twice faster(!) than VBox. Although VBA is inherently single-threaded, the Excel calculations, which take much more than a half of total computation time, supposedly aren't. So one would expect some speed gain when running on 2+ cores ("+" for hyperthreading). What we see is a speed loss. And quite big one too. For the VirtualBox the VT-d extension isn't a big deal. Can anyone shed some light on why the singlethreaded Windows kernel is so much faster than the SMP one?

  • Faking the date for a specific shell session

    - by Julien Nicoulaud
    I'm certainly trying to achieve something weird here, but I want to fake the date locally for a shell session on GNU/Linux. I need to black-box test how a program behaves at different dates, and modifying the system-wide date can have unwanted side effects (cron jobs, messed up logs, etc). Any ideas ?
