  • Browser with its own hosts file?

    - by Mystere Man
    I have a number of staging and test servers that I need to constantly modify my hosts file to access (they depend on the domain name, so i have to change the hosts file to get them to work). I find this annoying. I'd like to setup a portable browser of some kind for each kind of site i want to work with. Is there any version of any graphical web browser (including browsers based on the rendering engines of other browsers) that will do this? This way i can simply launch the instance that's already configured to work with staging if i want to test staging. Any ideas?

  • Netcat file transfer problem

    - by thepurplepixel
    I have two custom scripts I just wrote to facilitate transferring files between my VPS and my home server. They are both written in bash (short & sweet): To send: #!/bin/bash SENDFILE=$1 PORT=$2 HOST='<my house>' HOSTIP=`host $HOST | grep "has address" | cut --delimiter=" " -f 4` echo Transferring file \"$SENDFILE\" to $HOST \($HOSTIP\). tar -c "$SENDFILE" | pv -c -N tar -i 0.5 | lzma -z -c -6 | pv -c -N lzma -i 0.5 | nc -q 1 $HOSTIP $PORT echo Done. To receive: #!/bin/bash SERVER='<myserver>' SERVERIP=`host $SERVER | grep "has address" | cut --delimiter=" " -f 4` PORT=$1 echo Receiving file from $SERVER \($SERVERIP\) on port $PORT. nc -l $PORT | pv -c -N netcat -i 0.5 | lzma -d -c | pv -c -N lzma -i 0.5 | tar -xf - echo Done. The problem is that, for a very quick second, I see something flash along the lines of "Connection Refused" (before pv overwrites it), and no file is ever transferred. The port is forwarded through my router, and nmap confirms it: ~$ sudo nmap -sU -PN -p55515 -v <my house> Starting Nmap 5.00 ( http://nmap.org ) at 2010-04-21 18:10 EDT NSE: Loaded 0 scripts for scanning.

The receiver has no firewall, and outbound traffic on that port is allowed on the sender. I have no idea what to troubleshoot next. Any ideas? P.S.: Feel free to move this to SO/SF if you feel it would fit better there.

  • Does Ubuntu Server have any sort of cron job to automatically clear /tmp?

    - by DWilliams
    I know it clears out /tmp on reboots, but I haven't been able to find any sort of cron job on my server that clears /tmp. I recently set up a script that writes lots of files to /tmp and my server usually goes several months between reboots so I'm concerned about it being cluttered. I've seen several other distros that have a tmpwatch script installed by default. Ubuntu's repository seems to have replaced tmpwatch with tmpreaper. Is there any mechanism in place on Ubuntu (8.04 currently, soon to be upgraded to 10.04 when I get around to it) to clean up temp files on a server that doesn't regularly reboot or do I need to install tmpreaper?

  • why does and EBS volumes mounted in an Ubuntu 12.04 EC2 instance as /dev/sdh1 appear as /dev/xvdh1?

    - by Andres
    When mounting an EBS volume on ubuntu specified as /dev/sdh1 it actually mounts it at /dev/xvdh1. The aws console still thinks it's mounted at /dev/sdh1 so it took a while to realize that it was actually mounted, just in the wrong place I ran into this problem a long time ago using ubuntu on ec2. I just ran into it again https://forums.aws.amazon.com/post!reply.jspa?messageID=351382 and it seems like I'm not alone: https://forums.aws.amazon.com/thread.jspa?threadID=68957&tstart=0 I haven't found a good answer as to why this happens or how to fix it. Any ideas?

  • How to convert dvr-ms file in Ubuntu to DVD?

    - by edmicman
    I have a .dvr-ms file of a recorded TV show from my Vista Media Center. I would like to burn this to a DVD that can play on any standalone DVD player. My main PC that I want to use to convert it to a DVD format is running Ubuntu 10.04. I am able to play the file in Ubuntu using VLC (which surprised me) so I'm assuming I have what I need to decode it. I guess my questions are: What format do I need to convert this file to so that I could burn it to a playable DVD? I started to go through VLC's conversion process and chose I think H264 and AAC or something, and it gave a message about not having an AAC encoder. I'll look into that some more tonight, but is that something I could then burn to a DVD? Thanks for any help!

  • Linux file permissions not being preserved

    - by yellavon
    I am deploying some custom software as root (a necessity for this situation). I set the owner/group to user1:user1 and set all the files to 644 beforehand in shell, then copy and deploy with ant. However, when files get copied over from the deployment directory, the ownership changes back to root and all the files install with 666 permissions. This seems to occur whether the file is overwritten or newly created. I believe there is a way to set an option in cp, mv commands to preserve permissions, but that would be a lot of commands to change. How can I fix this? Is there some setting I can change temporarily for root so the install always preserves the file permissions?

  • Which group memberships are necessary for simple users in Ubuntu 12.04?

    - by Joey Carson
    I'm configuring Ubuntu 12.04 for my sister. I'd like to give her a system that she really can't screw up, but can still do normal things like install software. I don't want to just add her user to /etc/sudoers so that she can become root because she could possibly mess something up. I know that I should be able to get around this by just adding her to the necessary groups, but I'm not sure which ones those should be. Could anyone suggest them or point me in the direction of some kind of list that heavily used software in Ubuntu requires group membership?

  • Fresh install of 64bit Ubuntu needs flash but adobe doesn't have a version for me.

    - by DJTripleThreat
    I need flash to watch YT videos. YT said "You need to upgrade your Adobe Flash Player to watch this video." with a link to download flash. I'm running 10.04 so I see possible choices for myself: 1) a .deb file for Ubuntu 8.04+ or APT (whats this??) for Ubuntu 9.04. I downloaded the deb file and when I opened it in the installer it said that I have the wrong architecture. Anyone have an idea about how to work around this?

  • How to remove the Ubuntu Gnome desktop after making the switch to KDE?

    - by codeLes
    This is the opposite of this question. Basically I've been using Ubuntu for a while but decided to give KDE a shot so I went through the process of getting the latest KDE installed. I'm very impressed with KDE and the Kwin window manager seems like a better WM than Compiz which is what I was using for Gnome (sure that's an oppinion). This was an Ubuntu Jaunty install. So how do I go about removing the Gnome desktop? Is there an automated way similar to what my previous question covered? UPDATE: Should there be any packages I should NOT remove in the process?

  • How do I backup my Ubuntu 9.10 system and then restore it to a new machine with different hardware?

    - by EricJLN
    I have a nicely configured Ubuntu 9.10 machine, with crossover linux (from Codeweavers) installed. I have the Nvidia drivers installed. Everything is just as I want it. Now I want to move to a new machine with different hardware: different sized hard drive, different size RAM, different video card, etc. I tried the technique suggested on Ubuntu forums, "Howto: Backup and restore your system!". The results: New system complains about swap not being found New system complains about not finding Nvidia hardware, and I can't open the System-Administration-Hardware Drivers application (i.e., /usr/bin/jockey-gtk) to fix the problem. As result of nvidia, X-Windows is throwing errors, and the on screen process for fixing X-Windows isn't working. How do I restore a backup of my old system, including my Crossover Linux installation, to a new machine with different hardware installed?

  • replace windows xp with ubuntu no usb boot option and no cd?

    - by kristian nissen
    I have an old laptop running windows xp, I want to replace it with the latest version of ubuntu. The problem is that the laptop does not support boot from usb - I checked the BIOS but the option is not working, I tried http://www.pendrivelinux.com/testing-your-system-for-usb-boot-compatibility/ but with no luck. I also tried burning the iso on a dvd but the burn process keeps failing. What options do I have? Isn't it possible to install ubuntu somehow by downloading it and replacing it with the current OS?

    - by Kau-Boy
    I tried to switch from Java 5 to Java 6 using the "update-java-alternatives" command like explained on this page: https://help.ubuntu.com/community/Java But afterwards I get the following error when I tried to execute java: root@webserver:~# java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I also tried to reinstall the java binaries using "apt-get" but I didn't succeed reinstalling it. I would like to post the "apt-get" errors, but unfortunately I don't know how to print out the error messages in English and not in German. My system is a Ubuntu 8.04 ROOT server.

  • Basic networking: Centos Server Router + Ubuntu Client setup.. unable to access outside world from client

    I am trying to set up my Centos Server with two NICs as a router. eth0 is connected to the outside world and eth1 is connected to an Ubuntu client.

  • How do I back up my Windows partition from an Ubuntu live CD?

    - by lalli
    My Windows partition (C:) is corrupt. I'm booting up from an Ubuntu live CD and trying to copy all the files from C: to my external drive, but the system expands all of the links, producing a projected copy size of 1.8TB (my external drive is just 1TB, and the data in c: is around 700MB). Then I looked at dd and other backup utilities. Anything I looked into, I couldn't figure out whether or not the image would be readable in Windows through any other app. Has anyone else tried to back up data from a corrupted Windows installation using Ubuntu?

  • Windows file sharing connects over WiFi instead of LAN

    - by zacaj
    I have a laptop and a desktop computer, and I need to sync lots of files to the laptop and back whenever I go on a trip, etc. I've got a LAN cable connected into an extra port on the desktop that I plug into the laptop so I can get gigabit file transfers instead of wireless G. They connect fine. If I do an FTP transfer, for instance, using the LAN IP addresses, it goes at ~40MB/s, as it should. However when I copy files using explorer and native windows file sharing it detects the other computer by name, not IP (eg \\DESKTOP-PC\ instead of \\192.168.0.100\) and always connects to it by its wireless IP address instead of the faster LAN address. Both computers are running Windows 7. I have tried editing the priorities of the adapters in Advanced Settings and putting the LAN adapters above the wifi ones, but this didn't have any effect

  • Can I run ubuntu server 64 bit in a VirtualBox on a macbook host ?

    - by Doron
    Hello, I have a macbook pro with Intel Core 2 Due (It's actually not Pro, but it's a January 2009 unibody macbook - when there were both a unibody macbook, and a unibody macbook pro). I'm a php developer. I just installed a new hard drive, and in an effort to create a better development environment, I decided I'll try to create a virtual machine running ubuntu server. Since I need it to work fast (and since, well - it's just better, even if by a little) and I'll already have a delay due to the nature of the apache server being on a virtual host - I want to install a 64 bit version of ubuntu server. Can VirtualBox handle it? Is it s good idea to create such a development environment ? Thank you.

  • Windows 7 can't copy file - Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved

    - by JJGroover
    Any attempt to copy files larger than about 40 MB from a network share (a SAN running open filer / Samba) to my local machine running Windows 7 always results in the following error and the copy fails: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved. I've tried copying to my C: drive and a USB drive with the same results. Smaller files copy just fine. Clearly 40 MB is not that big of a file so I'm assuming it is some buggy interaction between windows 7 and Samba perhaps. Google has so far turned up nothing. Can anyone point me in the right direction?

  • Ubuntu Server 10.10 vs. Fedora Server 14 for Mono.NET app hosting in VM

    - by Abbas
    Ubuntu Server 10.10 vs. Fedora Server 14 I want to create a web-server running Mono, MySQL 5.5 and OpenLDAP running as a VM (on VMWare Workstation). Searching “Ubuntu Server vs. Fedora Server” mostly yields flame wars and noise. There are a few good articles available but they are either out-of-date or don’t offer very convincing arguments. I know the answer is most likely to be “it depends” but I wanted to harness the collective wisdom on ServerFault and get opinions, experiences and factual information to the extent possible. My selection criteria would be (other than what is mentioned above): Ease of use Ease of development Reliability Security

  • Copying single files into a folder that changes name every time the batch file is executed

    - by Daniel Jochem
    Can you please help, I am using this to put the text files made by the batch file into the folder created by the batch file as well. but my problem is that the name is changed of the new folder every time because it is named by the date and time it was created. This is the code: @echo off for /F " tokens=1,2,3* delims=/, " %%i IN ('date /T') DO ( set CUR_DAY_OF_WEEK=%%i set CUR_MONTH=%%j set CUR_DAY=%%k set CUR_YEAR=%%l) for /F " tokens=1,2,3* delims=:, " %%i IN ('time /T') DO ( set CUR_HOUR=%%i set CUR_MIN=%%j set AM_PM=%%k) if not exist E:\Private goto :F cd E:\Private md "E:\Private\%CUR_HOUR%.%CUR_MIN%%AM_PM% %j%%CUR_MONTH%-%CUR_DAY%-%CUR_YEAR%" goto :start :F if not exist F:\Private goto :G cd F:\Private md "F:\Private\%CUR_HOUR%.%CUR_MIN%%AM_PM% %j%%CUR_MONTH%-%CUR_DAY%-%CUR_YEAR%" goto :start :G cd G:\Private md "G:\Private\%CUR_HOUR%.%CUR_MIN%%AM_PM% %j%%CUR_MONTH%-%CUR_DAY%-%CUR_YEAR%" goto :start :start start /min A /stext A.txt start /min B /stext B.txt start /min C /stext C.txt start /min D /stext D.txt (As the directory (E:-G:) changes, how can I check all without an error?

  • How to make Ubuntu useradd behave like Centos useradd?

    - by Buttle Butkus
    I don't remember modifying CentOS useradd to get this behavior. useradd in CentOS creates the user's home directory with all the normal files (like .bashrc). I modified /etc/default/useradd to make it looks like CentOS (just required some uncommenting) except for Ubuntu having SHELL=/bin/sh instead of SHELL=/bin/bash How do I make useradd act like it does in CentOS? Is there some existing option to change? Or should I just add an alias to /etc/bash.bashrc? The difference: On Ubuntu, useradd is not creating the home directory. as root: $ useradd test $ cd ~test -su: cd: /home/test: No such file or directory
