  • Using command line to connect to a wireless network with an http login

    - by Shane
    I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something. Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.

  • Distributing a Python Software for Linux [closed]

    - by zfranciscus
    Hi, I am writing my first software in Python for Ubuntu (or Debian based Linux). I am looking for a good advise on the best way to distribute my software. The easist alternative that I can think of at the moment is to archive the python code into *.tar.gz, and let user execute the main python script as an executable to run the software. I realize that this may not be the best approach. I looked at the Debian maintainer guide: "http://www.debian.org/doc/maint-guide/ch-dother.en.html", not too sound lazy, but the guide looks very intimidating for a beginner. Are there any other tutorial that show how to create a debian package for a beginner ? If anyone has a suggestion do let me know. Thanks ^_^

  • Why my router alows to connect to the internet only after plugging the cord to laptop?

    - by gennad
    Hi all! I'm using Ubuntu 10.10. I have D-link dir-320 wireless router. When I turn on my laptop Lenovo G555, I'm trying to connect to router by it's usually unsuccessful. But if I'll pull the ethernet cord from the router and insert it into my laptop, everything will work well. And if after that I'll pull the ethernet cord from the laptop and insert it into the router, my laptop connects to the router and it will have Internet access via wifi. How to make the laptop directly connects to the Internet after booting without switching the cord?

  • Windows 8 safe mode grub 2

    - by Adam Smith
    I need to boot into safe mode in Windows 8 Ultimate to un-install Avira as this is not supported in windows 8. The problem is I have also installed Ubuntu 12.04 and from the grub 2, I do not get the option to boot into windows 8 safe mode. I do not have the CD/DVD of windows 8. Also, "pressing f8 as soon as you press enter after selecting win8 kernel " or for that matter any other key (Shift+F8, F2, F12 ) did not help. Is there a way to get an option in the boot menu to boot into Windows 8 safe mode? Found some similar posts, but could not find any relevant answers. Thanks

  • configuring linux server firewall to allow acces on a certain range of IP addresses

    - by eggman20
    Hi Guys, I'm new to linux server. I'm currently trying to get an Ubuntu 10.10 server up and running for the first time and I'm using Webmin for administration. I'm stuck on the setting up the firewall. What I need to do is to ONLY allow a range of IPs (e.g 128.171.21.1 - 128.171.21.100) to access the HTTP server and Webmin. I've seen a lot of tutorials but none of them fits what I needed. Thanks in advance!

  • Beast / CRIME / Beach attack and stopping it

    - by user2143356
    I have read so much on all this but not entirely sure I understand what has gone on. Also, is this one, two or three problems? It looks to me like three, but it's all very confusing: Beast CRIME Beach It seems the solution may be to simply not use compression with HTTPS traffic (or is that just on one of them?) I use GZIP compression. Is that okay, or is that part of the problem? I also use Ubuntu 12.04 LTS Also, is non-HTTPS traffic okay? So after reading all the theory I just want the solution. I think this may be the solution, but can someone please confirm I have understood everything so I am not likely to suffer from this attack: SOLUTION: Use GZIP compression on HTTP traffic, but don't use any compression on HTTPS traffic

  • Convert old videos to have smaller sizes

    - by Tim
    I have some videos from a few years ago,with various formats, such as avi, mpg, wmv, rm, rmvb, .... Their sizes are huge(more than 500 MB, and sometimes 1GB). Given there may likely be some advance in data compression, I would like to know which file formats and compression methods are recommended these days, by the standard that without losing obvious data, while achieving big size reduction. How can I perform the file format conversion and data compression in Ubuntu 12.04? Command line and batch ways would be the most convenient, although GUI ways are also appreciated. Thanks and regards!

  • When HDD becomes full, how to create a symbolic link to the data store on another disk?

    - by Brij Raj Singh
    I have a Linux Ubuntu machine which has an X GB hard disk. There is folder, say, /opt/software/data. The disk /dev/sda1 is almost full and I have attached another disk at /dev/sda2 which is mounted at /hdd2. Is it possible for me to link the folders /opt/software/data with /hdd2/software/data so, that every file get stored in the /hdd2/software/data but may be referred from the /opt/software/data? I can't do a reinstall of the software that creates this data, to change the default location of storage.

  • 'Singleton' application - or let the user only launch one instance of a program at the time

    - by Disco
    I'm running a few linux desktops; mainly for kids (yeah, trying to teach them the right OS at early stage) (running Ubuntu 10.10, Gnome) The problem is that they found very funny to make their workstations (actually, old 512 Mb pentium 4) by launching thousands of firefox instances. I'm looking for a way to restrict them to launch 'N' instances of a particular application. Haven't figured yet how. Thought of a monitoring daemon but I think that would be too ressources hungry. Any idea of a script/trick to achieve this ? Note: i might have 1-2 level of users (the kids, and the more grown up kids) so i have also to limit per user; something like user1: 3firefox, user2: 2firefox instances.

  • force connection using USB adapter

    - by James
    Hi all I am new to Linux, so even though this is probably a simple problem it remains unsolved after more then 3 hours of googling :-( I run running ubuntu 10.04 LTS on an Acer Aspire 5520G . the laptop has a wireless adapter, but since I wanted better range I got an Edimax EW-7711USN USB adapter. now , when running ifconfig I am able to see both adapters where as the laptop native adapter is listed as wlan0 and the usb adapter is listed as wlan1. but listing available networks from the wireless network applet , all the connection are listed under wlan0 , the usb adapter is costencly listed as disconnected. this is what I have been trying to do so far 1) ifconfig wlan0 down - I got disconnected from the net but still was not able to get the usb to connect 2) used the wireless connection dialog to connect to a hidden network with the usb adapter - I was able to connect to the network but with no Internet access 3) disable wireless using the laptop function button - both wireless adapters where disabled can anyone suggest a way to connect to to the wireless network using the USB adapter rather then the built in one ? Thanks

  • How can I fix my C++ compiler as it isn't loaded by default?

    - by GNR
    Recently I had installed the Ubuntu flavour of the Linux operating system. I had opened a terminal and just wrote a sample C program to check if it is compiling. When I saved the sample file and compiled with cc a.c, errors comes that the standard library is not loaded (i.e stdio.h). When I went to help pages, it says that the C or C++ compiler doesnt gets loaded by default and we should do it ourselves. So can anyone help me out to fix this problem, i.e to load the C/C++ compiler.

  • grep only returns help text

    - by Pete Mancini
    Well, I am perplexed. I am working with an Ubuntu server and I type in grep 'bash' *.sh BUT fgrep 'bash' *.sh works like a champ. which grep and which fgrep both point to their respective executables in /bin. I am perplexed as to what I am doing wrong. EXAMPLE output: $ grep -F 'grounding' repl.clj Usage: grep [OPTION]... PATTERN [FILE]... Search for PATTERN in each FILE or standard input. PATTERN is, by default, a basic regular expression (BRE). Example: grep -i 'hello world' menu.h main.c $ fgrep 'grounding' repl.clj (p/concepts-for-grounding-term imp1 "PERSON" "summary") See? grep is failing but fgrep is working fine. That is why I am perplexed.

  • RAID 1 after install and two controlers

    - by jfreak53
    I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this? Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point. Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process? Thanks.

  • what to use instead of laptop-mode?

    - by playcat
    hello, i have ubuntu 10.10 64bit on hp 6735s (turion processor). it overheats, and i'm forced to use turion power control in order to keep core temperature to a reasonable level. one more measure that i use is putting my processors to conservative mode. that way, i'm perfectly happy with its performance, and heat is where it should be. however, after my latest upgrade, something happened - cores are back to ondemand by default, and i'm not sure if turionpowercontrol is working any more (ps axu | grep urion shows no process). in addition, i read somewhere that laptop-mode uses hdd spindown for preserving data/energy, and that hdds have only a limited amount of those spindowns, so laptop-mode usage can actually shorten the life of my hdd. i'm wondering if there is a good way to set my cores to automatically go to conservative mode? also, what's the good way to see what is the voltage my cores use? on windows i use cpuz tools. thx and sorry for the long explanation.

  • Accessing subfolders of a windows share from linux

    - by Born2Smile
    Hi, at my work they have a funny setup: my home folder is a subfolder to a share, as such: \\server\share\subfolder Now I have full permissions to the subfolder, but no permissions to share. From windows I can connect to the VPN of my work place, type the above address into any address field, and voila: I see the contents of my home folder. In Linux (using Ubuntu) however, I can't figure out how to connect directly to the subfolder. Every attempt I can think of keeps returning "Access denied", because I don't have permission to view the share. Any help on how to connect to the subfolder would be greatly appreciated :) Cheers, Born2Smile

  • Bootmgr is missing for windows xp

    - by user1167074
    I know that there are so many posts on this subject but none of them worked for me. I have Ubuntu on my machine and I would like to install windows xp. As my cd/dvd reader does not work, I made a bootable usb from iso image using UNETBOOTIN, but when I try to boot in through USB it says "BOOTMGR is Missing". I have searched a lot but could not find any solution to it. Please note that my hard disk uses ext4 format and my bootable drive uses NTFS. I have set the Boot Sequence as USB Drive in BIOS. Please let me know if you need any additional information to fix this. Thanks

  • Partition falsly recognized as RAW

    - by Paul Hiemstra
    On my 2 TB data disk I have two primary partitions, one of 1.6 TB for data storage in Linux (ext3) and one of 300 GB for some additional data storage for Windows. I run a dual-boot Windows 7/Ubuntu 12.04 install. The issue I have that if I start my computer into Windows 7, bot the partitions on my 2TB data drive are not recognized. In stead, Windows 7 sees one 1TB partition with type RAW. However, if I reboot to Linux, and then back to Windows 7, the partitions are correctly recognized. The following two screenshots illustrate my situation. Before I reboot to linux: and after the reboot: I have two questions: What could cause this behavior? How can I solve this issue.

  • Unable to do Port Forwarding in Virtual Box

    - by dewbot
    I'm using Mac OS X 10.6. I have installed Virtual Box 4.1.0 in it. My Guest OS is Ubuntu Server 11.04. I have added a rule in Port Forwarding in Virtual Box - "guestssh" TCP 127.0.1.1 8080 127.0.0.1 1337 Inside Guest OS I'm running nodejs server. Code is nothing but simple helloworld code found on their site http://nodejs.org/. In short I'm running server on 127.0.0.1 on 1337 Port. Now according to rule I have given, from Host Machine all the requests for 127.0.1.1:8080 should be forwarded to 127.0.0.1:1337 of Guest OS. From Host I'm doing curl http://127.0.1.1:8080 and I'm getting curl: (7) couldn't connect to host Is there something am I doing wrong? Note- Don't give me suggestion to do ssh n all. As my ISP does not provide Internal LAN so its not possible in my case. All I can do it Port Forwarding.

  • Package temperature above threshold, cpu clock throttled

    - by drN
    I am running 64 bit Ubuntu 11.10 on an i7 with 8gigs of ram. I thought of putting this on askubuntu.com but decided that maybe the question has a much broader appeal. I have the following error message popping up when I run math simulations. CPUn: Core temperature above threshold, cpu clock throttled (total events = xxxxxxx) CPUn: Package temperature above threshold, cpu clock throttled (total events = xxxxxxx) I realize that this is a hardware warning message (machine check exception, correct me if I am wrong). How do I turn these messages off? Since it doesn't seem to have a detrimental effect of my calculations or my computer (presumably), I don't like it cluttering up my virtual console screen with hundreds of these messages.

  • How could all of my hard drives fail at once?

    - by Taylor
    I have an Ubuntu 13.04 server. Today I found the box had crashed. I restarted it, and now every single hard drive's partition table is missing. (1 SSD for /boot, /, and 3 2TB drives for RAID). I have the SSD connected to a laptop VIA USB-SATA cable, and sure enough, the partition table is missing. This tells me that the Motherboard / SATA controller / software actually broke the drives, not that they just can't be read correctly. Something similar happened to only the SSD a few months ago, and I was forced to just re-partition it. How the heck could his have happened? Bad Motherboard or SATA controller?
