scp vs netatalk, samba, and/or vsftpd with External USB drive

- by KitsuneYMG

I set up a ubuntu server machine to share an ext2 formatted external usb drive. When attempting to copy a single 275MB files from said device through netatalk, I get estimated download rates at around 45 min. With samba and ftp (using vsftpd) I get 1+ hours! Using scp to copy the file results in complete download within 5 minutes. Another option, ssh+cp from external device to ~ and then using netatalk to grab it from there results in a total time of arounf 7 minutes. Does anyone have a clue what is misconfigured? Assuming that nothing is, is there any fs/pseudo-fs that would use the internal hdd as an intermediate location/onion-layer for the external hdd (for reads only)? Details: AppleVolumes.default: /mnt/ext USB allow:username cnidscheme:cdb options:usedots,upriv

Automated Linux VMs on Hyper-V 2012

- by Mick

I have a requirement to create a ton of linux VMs for our customers (we run managed infrastructure) on Hyper-V 2012 in the coming months and I have an issue with automating it. Here is how I need it to work: User accesses their web page and creates a VM. VM is created with a unique IP and name User logs in over SSH I know Hyper-V quite well and can work with powershell and am a C# programmer so the development side of things is taken care of. I also know enough about Linux to be at least competent: I have used it on and off for a number of years but not done anything Enterprise-level with it. All this can be done easily by manual processes but I need to be able to script or program this to automate it as there could be hundreds of them being created but I don't know how. My first thought is to have a database with random-generated names and IPs already created but I don't know how to get a Linux VM to boot up and grab one from the database... I suppose a Kickstart script would take care of it but I don't know what to do from there. Here is what is bouncing around in my head: Create a std linux build. - Easy to do Someone clicks "Create VM" and I pull a name and IP from the database and write it to a kickstart script. - Easy to do I could then open the template VHDX file and copy in the script and then save it. - Not sure if possible User boots up new VM and the kickstart script gives it the name and IP I assigned it. My problem is that I don't know how to open a VHDX file and insert a kickstart script into it... can't figure it out. I am reaching here and this solution may be miles off... I am more used to creating Windows VMs with scripts and so on which i am more familiar with... any help would be appreciated. Thanks Mick

how to use iptables to block the IP of device connected to openwrt router

- by scola

I have two routers(A,B).the A connect to internet with IP:192.168.1.1 The openwrt router B connect the lan of A by bridge with static IP:192.168.1.111. I am learning to use iptables to control the devices connected to B(wlan) . I use my phone to connect wifi of B,the phone's IP is IP:192.168.1.100.it can surf the internet normally. I want to block the phone's IP to make the phone can not connect to internet. refer to http://bredsaal.dk/some-small-iptables-on-openwrt-tips iptables -A input_wan -s 192.168.1.100 --jump REJECT iptables -A forwarding_rule -d 192.168.1.100 --jump REJECT but it do not work.the phone still connect to internet normally. and I tried other chain(INPUT,OUTPUT,FORWARD).so many chains confused me. iptables -I OUTPUT -o br-lan -s 192.168.1.100 -j DROP and it do not work again.

Devices renamed with udev not working, original device node still there

- by skerit

I'm trying to rename certain video devices using udev. Here's a rule (broken down for readability): ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="1", ATTR{devpath}=="2", ATTR{idVendor}=="05e1", NAME="video97" It works. /dev/video97 is created But the original /dev/video1 node is STILL there. The even worse, when I try to view the /dev/video97 node in guvcview it doesn't work, while the original node DOES work.

Multi device BTRFS filesystem with disk of different size

- by fokenrute

I have an existing BTRFS filesystem composed of one 500GB disk and I just bought a 2TB disk to increase the storage capacity of my home server and I want add the new disk to the existing filesystem. From what I read, it seems like no BTRFS setup can handle disk of different sizes without wasting the difference in size between the larger and the smaller disk, but I'm new to BTRFS and I might have missed something, so is there a setup that can allow me to combine two disks in a filesystem without wasting space ?

Write once, read many (WORM) using Linux file system

- by phil_ayres

I have a requirement to write files to a Linux file system that can not be subsequently overwritten, appended to, updated in any way, or deleted. Not by a sudo-er, root, or anybody. I am attempting to meet the requirements of the financial services regulations for recordkeeping, FINRA 17A-4, which basically requires that electronic documents are written to WORM (write once, read many) devices. I would very much like to avoid having to use DVDs or expensive EMC Centera devices. Is there a Linux file system, or can SELinux support the requirement for files to be made complete immutable immediately (or at least soon) after write? Or is anybody aware of a way I could enforce this on an existing file system using Linux permissions, etc? I understand that I can set readonly permissions, and the immutable attribute. But of course I expect that a root user would be able to unset those. I considered storing data to small volumes that are unmounted and then remounted read-only, but then I think that root could still unmount and remount as writable again. I'm looking for any smart ideas, and worst case scenario I'm willing to do a little coding to 'enhance' an existing file system to provide this. Assuming there is a file system that is a good starting point. And put in place a carefully configured Linux server to act as this type of network storage device, doing nothing else. After all of that, encryption on the files would be useful too!

Suspending/Screen Going Off When Still In Use (Ubuntu & Arch)

- by luke

I have a laptop (HP Pavilion G6) that was running Ubuntu and for a while now (at least 6 months) has been having a problems randomly suspending whilst still in use with a full battery and still being charged. Originally the problem was with Ubuntu so I first attempted to disable suspend using every way I could find (gui settings + dconf editor) this didn't work and it still kept suspending so I ended up switching to Arch Linux. Unfortunately not long after switching to Arch Linux I ended up experiencing the same problems. So yet again I modified the settings in /etc/systemd/logind.conf to prevent it from suspending and this time it worked, kind of. Now I am experiencing the screen going off and I have to change to a different tty (by using ctrl-alt-fx, which was something I also found I had to do sometimes when waking up from suspend in Ubuntu) to get the screen to go back on. The strange thing is this only happens when running a Linux distros and only occasionally (e.g. it may happen once/twice a week at most). But when it does happen it can happen multiple times in a row. And it only seems to happen when I am using it. This may just mean that it hasn't happened yet when I am not but generally if I leave it to run something or play a video it hasn't occurred only when I am using it regardless of which program I am using (e.g. it has occurred when using firefox, vim, even when using a virtualbox vm). At first I thought it could be the CPU temperature but after monitoring it I discovered it occurred a lot of the time when my CPU was less than 50 °C. I then checked /var/log/* but could not see anything related to it suspending only a few standard things from when it was woken up. I am really out of ideas and really hoping someone can help. Thanks in advance.

Triple monitor setup in linux

- by Brendan Abel

I'm hoping there are some xorg gurus out there. I'm trying to get a three monitor setup working in linux. I have 2 lcd monitors and a tv, all different resolutions. I'm using 2 video cards; a 9800 GTX and 7900Gt. I've seen a lot of different posts about people trying to make this work, and in every case, they either gave up, or Xinerama magically solved all their problems. Basically, my main problem is that I cannot get Xinerama to work. Every time I turn it on in the options, my machine gets stuck in a neverending boot cycle. If I disable Xinerama, I just have three Xorg screens, but I can't drag windows from one to the other. I can get the 2 lcds on Twinview, and the tv on a separate Xorg screen no problem. But I don't really like this solution. I'd rather have them all on separate screens and stitch them together with Xinerama. Has anyone done this? Here's my xorg.conf for reference. p.s. This took me all of 30 seconds to set up in Windows XP! p.s.s. I've seen somewhere that maybe randr can solve my problems? But I'm not quite sure how?

Does OS X support linux-like features?

- by Xeoncross

I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used. However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers. The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux. Anyway, I am now looking at moving to a MAC in the hope of finding a stable GUI and a feature-packed command line. Does Mac OS have an integrated command line where I can do linux-like-awesomeness like rsync, ssh, wget, crong jobs, package updates, and git without having an unstable GUI? Basically, until the linux GUI applications get a little better, is OS X what I need?

Two distinct mount points with one device

- by user1761555

After being disappointed with Ubuntu's release update feature, I finally decided to have separate mount points for / and /home. Towards this, I reformatted my HDD giving most of my drive to sda1(meant to be /home) and allocated about 40GB to rootfs (/). Unfortunately, I would also like to have a /projects which is to be located on sda1. Currently, sda1 is being mounted as /dev/sda1 on /home type ext4 (rw) I've tried looking online for a solution to this problem..however, I'm not sure as to what to look for! Is it possible to mount the 'home' directory of sda1 as /home and 'projects' directory of sda1 as /projects?

Connecting MS SQL using freetds and unixodbc: isql - no default driver specified

TotalPhase Aardvark driver's GPL license

- by Philip

I'm using an SPI host adapter for a project. The Aardvark from TotalPhase. And I did something crazy, I read that EULA license that everyone just clicks through. The driver installation license includes these bits: This driver installer package also includes a WIN32 driver that is entirely based on the libusb-win32 project (release 0.1.10.1). ... LICENSE: The software in this package is distributed under the following licenses: Driver: GNU General Public License (GPL) Library, Test Files: GNU Lesser General Public License (LGPL) Now, my understanding of of the GPL is that it's sticky and viral. If you include software then the whole project has to be released under the GPL (if you distribute it, you can do whatever you want with in-house projects). If the driver was like the library, and was licensed under the LGPL, it could be used by my closed source proprietary project, as long as it's source and license was passed along with it. But it's not, it's pure GPL. If I include this driver in my project and distribute it, am I required to release my project under the GPL?

Wammu - USB Device Name?

- by Paul

I'm trying to get to my phone's filesystem through USB in Wammu, but I'm stuck in the configuration wizard when it asks for a USB device name. After about an hour of Internet searching, here are the failed solutions I've already tried, starting with the relevant information returned by lsusb in terminal. lsusb Bus 001 Device 003: ID 12d1:101e Huawei Technologies Co., Ltd. So I tried opening Wammu through sudo wammu in terminal and inputting "/dev/bus/usb/001/003" as the device name, which returns: Error opening device Device /dev/bus/usb/001/003 does not exist! and then "/dev/bus/usb/001/", which returns: Failed to connect to phone Description: Error opening device. Unknown, busy, or no permissions.<br> Function: Init<br> Error code: 2 Another proposed solution was to try "tail -f /var/log/messages" in terminal. But that only returned a "No such file or directory" message.

Digital Signature Device Recommendations (Mini Tablet)

- by blu

I'd like to capture signatures of application users with a mini-tablet/little pos signature device. I welcome any first hand experiences of which ones were good and which ones to stay away from. Off the top of my head I can think of a few features I'd like to see: USB interface Not too expensive (I don't know 100-200 dollars?) Be easy to integrate with a managed .NET application Also I realize most people, myself included, think of digitally signing assemblies with code instead of a mini-tablet device, if there is a more accurate phrase for this pleas let me know. Thanks for any input.

Query size of block device file in Python

- by ??O?????

Hello. I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device size) remains, and it's not answered here, so I open this question. I am aware of the following two related SO questions: Determine the size of a block device (/proc/partitions, ioctl through ctypes) how to check file size in python? (about non-special files) Therefore, I'm asking: in Python, how can I get the file size of a block device file?

Measuring device drivers CPU/IO utilization caused by my program

- by Lior Kogan

Sometimes code can utilize device drivers up to the point where the system is unresponsive. Lately I've optimized a WIN32/VC++ code which made the system almost unresponsive. The CPU usage, however, was very low. The reason was 1000's of creations and destruction of GDI objects (pens, brushes, etc.). Once I refactored the code to create all objects only once - the system became responsive again. This leads me to the question: Is there a way to measure CPU/IO usage of device drivers (GPU/disk/etc) for a given program / function / line of code?

Shell script to name videos on device

One Linux server has two timer

- by garconcn

The time on one of our Linux box is very weird. Whenever I call date 3 times, the 4th call will give a wrong time(usually 1 hour later). I have setup cron to sync with ntp server. We have 20+ similar servers, only this one has this problem. Any idea? Thanks.

OSX pdf-kit vs Linux poppler or pdf/x

- by Tahnoon Pasha

I keep reading and hearing that the reason that there is no good pdf editing software for Linux is that the libraries are not as well developed. That is why there is no equivalent for Skim or Preview in Linux. I had a look a the pdf-kit documentation and the poppler documentation and they looked very similar to my admittedly non-technical view. Could someone explain to me why the OSX libraries (eg) are so much easier to write projects like Skim in than the linux ones. I'm not sure if the same applies to OSX projects to NVAlt, but it seems to be a common theme - I'd just like to understand what is behind the thesis that OSX is easier to code these projects in, and what would be involved in changing it. (I'm not disputing the value of Okular or Evince and the like, just noting that they don't have the richness of functionality of Skim, Preview or even things like Goodreader on the Ipad).

Linux & Windows Boot Up Times in Amazon Web Service and Windows Azure

- by Adron

I've been working with Windows Azure and Amazon Web Services EC2 for a good many months now (almost getting to the years range) and I've seen something over and over that seems troubling. With AWS & Linux I commonly get instance startup times with EC2 around the 1-3 minute range. With AWS & Windows OS on an EC2 instance it often takes 10-20 minutes. With Windows Azure Web or Service Role I often get anywhere from 6-30 minutes waiting for a role to startup. I assume of course this involves booting up a windows instance somewhere in the fabric. I know there has always been tons of FUD about windows vs. Linux, but I'd really like to know why it is that Windows 08 or 03 boots so much slower in the cloud than Linux. Any specific technical information regarding this would be greatly appreciated! Thanks.

Vi on Linux: show ^M line endings for DOS-format files

- by sss

On Solaris, if you open a file in vi that has Windows line endings, this shows up as ^M at the end of every line. On Linux, vi is cleverer and understands the Windows file format, and does not display ^M. Is there a setting to make Linux vi behave the same as Solaris in this respect? A common problem for us is copying a shell script off a (Windows) dev box and forgetting to dos2unix it, and then being confused when it doesn't work properly. On Solaris the problem is obvious as soon as you vi the file, but not on Linux. Thanks.

front end to linux std mailbox for development purposes

- by Fabio

I am actually a software developer, do have a fair amount of linux experience as a user though since 1997. I am normally on stackoverflow.com, please excuse me if this question isn't appropriate here. I am working on a web project. We send out emails. I work locally on a linux box. When coding I use my local mailboxes to check what's been sent. Emails sent out to valid email addresses are not arriving at my official mailbox; they might be stopped by the provider's mail servers (gmail, yahoo). Now, we are sending out HTML mails too. I need to check how they look like. Is there a GUI frontend to the standard linux BSD mailbox? Or should I install some IMAP/POP server for this? Will such server get the emails sent to username@localhost ? Thanks for any suggestion
