• How To Create An FTP User That Has Permission To EVERYTHING

  - by Serg

  I've spent the last two hours trying to create an FTP user so I can transfer some files over to my Wordpress blog folder. /var/www/sergiotapia.me I'm using vsftpd and Ubuntu 12.04 for my FTP server and I've read tons of documentation, none of which seem to work. I still cannot log in with the FTP user, let alone test if I even have the read/write file permissions. Can a Linux guru here, help me out with a small step by step? I'm comfortable with the terminal and nano, so that's not an issue - I'll SSH into my box. Just tell me what to do and what commands to run. Specifically, this user needs to have read and write access to the /var/ folder and anything within it. I want to have 1 user that can do whatever the heck he wants on my Ubuntu 12.04 VPS machine.

• PHPMyAdmin HTTP auth works, but not cookie auth

  - by ssmy

  I'm running PHPMyAdmin version 3.3.2 on Ubuntu 10.04, fully updated. Recently, the authentication for PHPMyAdmin stopped working. It would return the error 1045. However, login on the command line still worked. I switched to HTTP authentication instead of cookie auth, and now it works fine. Any ideas why this could be, or what I could do to make cookie auth work again? (Partly just to know, and partly since it's a bit nicer).

• How does the os know which paramater to pass to /etc/init.d/

  - by iDev247

  I've been working with linux for a while but in a rather simple manner. I understand that scripts in init.d are executed when the os starts but how exactly does it works? How does the os know which paramater to pass to a script? To start apache I would do sudo /etc/init.d/apache2 start. If I run sudo /etc/init.d/apache2 it doesn't work without the start. How does the os pass start to the script?

• Address VMWare Fusion Linux guest by hostname?

  - by amrox

  I have a Ubuntu Server 9.04 image set up in VMWare Fusion 3.0.0, using the NAT option for the guest's network connection. From the Mac host, I can ssh to the linux guest just fine using it's IP address, but I would like to be able to refer to it by hostname for connivence. ie: mac-host:~ ssh [email protected] I had a similar setup using Parallels a couple years ago, but I don't remember how it was set up. It may have "just worked". Any suggestion on how to make this work?

• Dual-head monitor system Kubuntu 10.04

  - by andrii

  I have a notebook Asus V6X00V with 1400*1050 monitor(name: LVDS) and Dell Monitor 1920*1080 (VGA-0). I want to have a dual monitor system. At MS Windows everything is working fine. During the Kubuntu installation the Dell and the main notebook monitors have a right resolutions(1920*1080 & 1400*1050). But after some stage it have been changed to the 1152*864 for both. Now the right resolution is only during turning off process and when I am using the console. So it shows that system can use this resolutions. The problem is just in a settings. I am using Size & Orientation - System Settings for setting adjustment. Any option that changes resolution for any monitor or changing position(Absolute, Left Of, Right of and so on) cause the color line noise on the screens. I have tried xrandr: xrandr --output LVDS --mode 1400x1050 --pos 0x0 --output VGA-0 --mode 1920x1080 --right-of LVDS --pos 1400x0 but have received the same result. I have find out that for example the previous version of Randr(1.2, now I have xrandr 1.3) need a xorg.conf file modification to create a big virtual screen, but kubuntu 10.4 don't have xorg.conf and I don't know should I modify xorg for 1.3 version of xrandr or not. Please help me to solve this problem

• Update in grub.cfg file for loading new kernel image in Ubuntu 11.04

  - by user1627657

  I am new to Linux. I am compiling Linux kernel (ver: 2.6.34.12) in gcc in traditional manner in VMware machine in Ubuntu (kernel version - 2.6.38-8-generic) 11.04 version. I am unable to find, where to update about newly compiled kernel in the grub.cfg file. I updated the newly created image version name in the existing image. Then VMware didn't able to load new kernel. I have searched in internet but I didn't find. So anyone can help me, to update in the grub.cfg and to successfully load new kernel. Few things about what I have done: Make bzImage to create image file. Make modules_install && make install to install modules and then sudo mkinitramfs -o initramfs.img-2.6.34 2.6.34. Then sudo gedit grub.cfg. In that at the mementry I updated the version of vmlinuz and initrd from 2.6.38-8 to 2.6.34.12. This is I have done.

• Does anyone know how to "tcpdump" traffic decrypted by Mallory MITM? [migrated]

  - by chriv

  I'm looking for some help in capturing network traffic that I can analyze in Wireshare (or other tools). The tool I'm using is mallory. If anyone is familiar with mallory, I could use some help. I've got it configured and running correctly, but I don't know how to get the output that I want. The setup is on my private network. I have a VM (running Ubuntu 12.04 - precise) with two NICs: eth0 is on my "real" network eth1 is only on my "fake" network, and is using dnsmasq (for DNS and DHCP for other devices on the "fake" network) Effectively eth0 is the "WAN" on my VM, and eth1 is the "LAN" on my VM. I've setup mallory and iptables to intercept, decrypt, encrypt and rewrite all traffic coming in on destination port 443 on eth1. On the device I want intercepted, I have imported the ca.cer that mallory generated as a trusted root certificate. I need to analyze some strange behavior in the HTTPS stream between the client and server, so that's why mallory is setup in between for this MITM. I would like to take the decrypted HTTPS traffic and dump it to either a logfile or a socket in a format compatible with tcpdump/wireshark (so I can collect it later and analyze it). Running tcpdump on eth1 is too soon (it's encrypted), and running tcpdump on eth2 is too late (it's been re-encrypted). Is there a way to make mallory "tcpdump" the decrypted traffic (in both directions)?

• Linux boot - stop the kernel switching to a new framebuffer mode clearing output

  - by Avio

  I'm working on an embedded system (based onUbuntu 12.04 LTS) and I'm customizing its kernel. I'm having some problem with upstart, mountall and plymouth. Nothing unsolvable I suppose, but the real problem is that I can't diagnose properly what's going on because the kernel (or maybe plymouth) changes the video mode in the middle of the boot process. This completely wipes entire lines of log and prevents any debugging of kernel misconfigurations. My Grub2 config seems to be ok with: GRUB_CMDLINE_LINUX="" GRUB_CMDLINE_LINUX_DEFAULT="acpi=force noplymouth" GRUB_GFXMODE=1024x768x32 GRUB_GFXPAYLOAD_LINUX=keep Here is some relevant output of lspci: 00:00.0 Host bridge: Intel Corporation Mobile 945GSE Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) And here is the relevant portion of my kernel configuration: CONFIG_AGP=y CONFIG_AGP_INTEL=y CONFIG_VGA_ARB=y CONFIG_VGA_ARB_MAX_GPUS=16 CONFIG_DRM=y CONFIG_DRM_KMS_HELPER=y CONFIG_DRM_I915=y CONFIG_DRM_I915_KMS=y CONFIG_VIDEO_OUTPUT_CONTROL=y CONFIG_FB=y CONFIG_FB_BOOT_VESA_SUPPORT=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y CONFIG_FB_MODE_HELPERS=y CONFIG_FB_VESA=y CONFIG_BACKLIGHT_LCD_SUPPORT=y CONFIG_BACKLIGHT_CLASS_DEVICE=y CONFIG_VGA_CONSOLE=y CONFIG_VGACON_SOFT_SCROLLBACK=y CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=640 CONFIG_DUMMY_CONSOLE=y CONFIG_FRAMEBUFFER_CONSOLE=y CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y CONFIG_FONT_8x8=y CONFIG_FONT_8x16=y CONFIG_LOGO=y CONFIG_LOGO_LINUX_MONO=y CONFIG_LOGO_LINUX_VGA16=y CONFIG_LOGO_LINUX_CLUT224=y Every other custom/stock kernel boot fine with that Grub2 config. What I would like to have is a single flow of messages on a single console (retaining one screen resolution) from the bootup logo till the login prompt. Does anybody know what I have to tweak to achieve this?

• Install Navicat for MySQL on Linux Ubuntu 12.04

  - by DanielAttard

  How do I install Navicat on Ubuntu Desktop 12.04? I have just configured a new Ubuntu 12.04. Because I'm not so familiar with the command line, I prefer to use Ubuntu Desktop so that I can have a GUI. Now I need to install a front-end to connect with MySQL. I prefer to use Navicat in a MAC environment, so I was hoping to install Navicat on the Ubuntu machine. I downloaded a Linux copy of Navicat for MySQL from here: http://www.navicat.com/download/navicat-for-mysql The problem I am having is that I don't know how to install the program after it has been downloaded. There is a navicat.exe file in the navicat folder, but that seems to be for a DOS/Windows environment. I just can't figure out how to install Navicat onto Ubuntu Desktop 12.04. Anyone have any ideas? Thanks.

• Play framework 2.2 using Upstart 1.5 (Ubuntu 12.04)

  - by Leon Radley

  I'm trying to get Play 2.2 working with upstart. I've been running Play 2.x with upstart since it's release and it's never been a problem. But since the release of 2.2 and the change to http://www.scala-sbt.org/sbt-native-packager/ play doesn't want to start any more. Here's the config I'm using description "PlayFramework 2.2" version "2.2" env APP=myapp env USER=myuser env GROUP=www-data env HOME=/home/myuser/app env PORT=9000 env ADDRESS=127.0.0.1 env CONFIG=production.conf env JAVAOPTS="-J-Xms128M -J-Xmx512m -J-server" start on runlevel [2345] stop on runlevel [06] respawn respawn limit 10 5 expect daemon # If you want the upstart script to build play with sbt pre-start script chdir $HOME sbt clean compile stage -mem $SBTMEM end script exec start-stop-daemon --pidfile ${HOME}/RUNNING_PID --chuid $USER:$GROUP --exec ${HOME}/bin/${APP} --background --start -- -Dconfig.resource=$CONFIG -Dhttp.address=$ADDRESS -Dhttp.port=$PORT $JAVAOPTS I've changed the JAVAOPTS to include the -J- and I've also changed the path to use the new startscript located in the /bin/ dir. I've read that upstart 1.4 has setuid and setguid. I've tried removing the start-stop-daemon but I haven't got that working either. Any suggestions would be appreciated.

• Adding Multiple Interfaces to EC2 Ubuntu 12.04

  - by nocode

  I have a m1.medium Ubuntu 12.04 instance with two ENI's. I have a VPC setup with a private and public subnet. Private: 10.50.1.0/24 Public: 10.50.101.0/24 I initiated the instance on the private subnet. I configured a NAT instance and route all servers in the private subnet internet access. The route tables on the private subnet point towards the NAT instance and the route table on the public subnet point to the internet gateway. I am trying to add a public interface on the machine so that I can put it behind a ELB. When I added the second ENI and configured a static IP in /etc/network/interfaces and restarted the network services, I can no longer access from the Public subnet to the Private Subnet. Works Private private Private public Does not work Public private From Public Private, I ran a TCPDUMp on the private machine and can see the request coming in. My guess is it's trying to route over the new Public interface instead of the Private. Here's my route: default 10.50.1.1 0.0.0.0 UG 100 0 0 eth0 10.50.1.0 * 255.255.255.0 U 0 0 0 eth0 10.50.101.0 * 255.255.255.0 U 0 0 0 eth1 My networking knowledge is limited and I believe I have to add some routes but unsure of what command/syntax needs to be.

• Ubuntu 10.04 boot splash screen and themes broken

  - by thezachperson31

  I recently upgraded to the release candidate of Ubuntu 10.04. Since then, two problems have occurred and persisted: the boot splash screen has reduced down to a black screen with random color blocks/text/gibberish at the top; and the themes are broken, as in the light themes have checkboxes in menus the same color as the background, and the dark themes don't correctly change the font colors in the top menu. Help? On a side note, is there a need to upgrade from 10.04 RC to LTS?

• Daemons did not start automatically ubuntu 10.04

  - by Anton Prokofiev

  Hello, All! I have a strange behavior on Ubuntu 10.4: few daemons (apache2 and postgresql (8.4SS from enterpriseDB) did not start automatically. Funny things that time-to-to they do. (If I just restart my computer everything looks ok, but if I turn it off for the night, nothing work..., so I have to start them manually) I've googled this problem a little bit, but the only answer I have found was to run: sudo update-rc.d apache2 defaults I've called it but the answer was: System start/stop links for /etc/init.d/apache2 already exist. Any Ideas?

• Java JRE: Setting default heap size

  - by AndiDog

  I'm having trouble with Java on a virtual server, it always gives me the following error: # java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I first solved this by using the CACAO virtual machine (of OpenJDK, by putting it first in jvm.cfg), but then I run into problems with my web application (Play! framework based, gives me nasty LinkageErrors). So I cannot use that VM. Instead I'd like to just use the normal server VM and set -Xmx128M by default. How can I do that? Related: this question

• Bash script getting automatically deleted from Ubuntu 12.04 Server?

  - by Kris Anderson

  I'm running a bash script on an ubuntu 12.04 through cron. The script works fine for a few weeks (runs daily backups of websites, mysql databases, and copies to Amazon S3). However, twice now I've noticed that backups stopped happening. Both times the backup script (backupscript.sh) located in my home folder was no longer there. No one else has access to this server, so nothing was manually changed on the server and no one deleted the file by mistake. The cron job (nano /etc/crontab) still references this script, but the script itself disappears. What could cause this to happen? Does Ubuntu delete the script if it runs into some sort of error?

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• Link to a folder in the top Ubuntu panel

  - by Seamus

  Hi. I like the little top panel thing in Ubuntu. I have links to all my most used programs on there. (Which is why I don't see the point of docky or any of those things: they seem to do the same job, but they're messier). What I'd like is to have a little icon for my documents folder up there too. But I don't seem to be able to do it. It's not one of the options listed when you go to "add to panel...". Am I missing something ridiculously easy?

  As suggested I upgraded. Same as before except now not even the speaker control in the application bar. Please help. Background: I have Ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal and ran alsamixer which seems to recognize my sound card, though the driver is not listed in System Administration Hardware Drivers; the only driver listed is my graphics card. Setup: I have a Dell 8250. Speakers are plugged into the SB live card. Woofer and 2 speakers using transformer.
