• Right-aligning button in a grid with possibly no content - stretch grid to always fill the page

  - by Peter Perhác

  Hello people, I am losing my patience with this. I am working on a Windows Phone 7 application and I can't figure out what layout manager to use to achieve the following: Basically, when I use a Grid as the layout root, I can't make the grid to stretch to the size of the phone application page. When the main content area is full, all is well and the button sits where I want it to sit. However, in case the page content is very short, the grid is only as wide as to accommodate its content and then the button (which I am desperate to keep near the right edge of the screen) moves away from the right edge. If I replace the grid and use a vertically oriented stack panel for the layout root, the button sits where I want it but then the content area is capable of growing beyond the bottom edge. So, when I place a listbox full of items into the main content area, it doesn't adjust its height to be completely in view, but the majority of items in that listbox are just rendered below the bottom edge of the display area. I have tried using a third-party DockPanel layout manager and then docked the button in it's top section and set the button's HorizontalAlignment="Right" but the result was the same as with the grid, it also shrinks in size when there isn't enough content in the content area (or when title is short). How do I do this then? ==EDIT== I tried WPCoder's XAML, only I replaced the dummy text box with what I would have in a real page (stackpanel) and placed a listbox into the ContentPanel grid. I noticed that what I had before and what WPCoder is suggesting is very similar. Here's my current XAML and the page still doesn't grow to fit the width of the page and I get identical results to what I had before: <phone:PhoneApplicationPage x:Name="categoriesPage" x:Class="CatalogueBrowser.CategoriesPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" SupportedOrientations="PortraitOrLandscape" Orientation="Portrait" mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768" xmlns:ctrls="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" shell:SystemTray.IsVisible="True"> <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <StackPanel Orientation="Horizontal" VerticalAlignment="Center" > <TextBlock Text="Browsing:" Margin="10,10" Style="{StaticResource PhoneTextTitle3Style}" /> <TextBlock x:Name="ListTitle" Text="{Binding DisplayName}" Margin="0,10" Style="{StaticResource PhoneTextTitle3Style}" /> </StackPanel> <Button Grid.Column="1" x:Name="btnRefineSearch" Content="Refine Search" Style="{StaticResource buttonBarStyle}" FontSize="14" /> </Grid> <Grid x:Name="ContentPanel" Grid.Row="1"> <ListBox x:Name="CategoryList" ItemsSource="{Binding Categories}" Style="{StaticResource CatalogueList}" SelectionChanged="CategoryList_SelectionChanged"/> </Grid> </Grid> </phone:PhoneApplicationPage> This is what the page with the above XAML markup looks like in the emulator:

• Removing file with strange characters in filename in OS X

  - by SiggyF

  After a memory error in my program, I am stuck with a file with a strange filename. It's proving quite resistant to all normal methods to remove files with strange names. The filename is: %8BUȅ҉%95d%F8%FF%FF\x0f%8E%8F%FD%FF%FF%8B%B5T%F8%FF%FF%8B%85\%F8%FF%FF\x03%85x%F8%FF%FF%8B%95D%F8%FF%FF%8B%BD%9C%F8%FF%FF%8D\x04%86%8B%B5@%F8%FF%FF%89%85%90%F8%FF%FF%8B%85X%F8%FF%FF\x03%85%9C%F8%FF%FF%C1%E7\x02%8B%8Dx I tried the following: rm * - "No such file or directory" rm -- filename - "No such file or directory" rm "filename" - "No such file or directory" ls -i to get the inode number - "No such file or directory" stat filename - "No such file or directory" zip the directory where the file is in - error occured while adding "" to the archive. delete directory in finder - error -43 in python: os.unlink(os.listdir(u'.')[0]) - OSError No such file or directory find . -type f -exec rm {} \; - "No such file or directory" checked for locks on the file with lsof - no locks All these attempts result in a file (long filename here) not found error, or error -43. Even the ls -i. I couldn't find anymore options, so before reformatting or repairing my filesystem (fsck might help) I thought maybe there is something I missed. I wrote this small c program to get the inode: #include <stdio.h> #include <stddef.h> #include <sys/types.h> int main(void) { DIR *dp; struct dirent *ep; dp = opendir ("./"); if (dp != NULL) { while (ep = readdir (dp)) { printf("d_ino=%ld, ", (unsigned long) ep->d_ino); printf("d_name=%s.\n", ep->d_name); } (void) closedir (dp); } else perror ("Couldn't open the directory"); return 0; } That works. I now have the inode, but the normal find -inum inode -exec rm '{}' \; doesn't work. I think I have to use the clri now.

• SSH to drive letter in Windows 2003

  - by JohnnyG76

  I have a Windows 2003 server running a SSH server (WRQ Reflection), how would I ssh to it and specify a specific drive letter? (like the D: drive) ex: from another workstation: ssh [email protected] d: When I do that it fails and I get this error: "exec request failed on channel 0" If I simply SSH to that same windowsbox without trying to specify a drive letter I get a Windows (CMD.EXE) command prompt shell on the C: drive. I can then run any windows command. Thanks

• Proper way to configure ~/.Xsession with a standalone window manager to gracefully end a session

  - by cYrus

  I'm using xdm and my ~/.Xsession looks like this: # <initialization stuff here> exec openbox It works, but I've noticed that when I log out Openbox doesn't gracefully kill all the applications. In particular Google Chrome complains about that. How can I make sure to wait for all processes to exit (just like others configurations: Gnome, KDE, Windows ...)? The only (ugly) solution that I've found involves sleep and kill into ~/.Xsession.

• How do I traverse the filesystem looking for a regex match?

  - by editor

  I know this is teeball for veteran sysadmins, but I'm looking to search a directory tree for file contents that match a regex (here, the word "Keyword"). I've gotten that far, but now I'm having trouble ignoring files in a hidden (.svn) file tree. Here's what I'm working with: find . -exec grep "Keyword" '{}' \; -print Reading sites via search I know that I need to negate the name flag, but I can't it working in the right order.

• Exclude all hidden directories in UNIX find

  - by xRickerlx

  I'm doing a word search using the following command: find . -exec grep -q [some_word] '{}' \; -print -o -name .svn -prune -o -name .ssh -prune -o -name .boneyard -o -name log -prune -prune -o -name tmp -prune Is it possible to use a regex to exclude all hidden directories? Note: The current command traverses the entire tree from the current location and exclude those being pruned. The exclusion needs to work for any hidden directory regardless off location.

• Oracle Linux Tips and Tricks: Using SSH

  - by Robert Chase

  Out of all of the utilities available to systems administrators ssh is probably the most useful of them all. Not only does it allow you to log into systems securely, but it can also be used to copy files, tunnel IP traffic and run remote commands on distant servers. It’s truly the Swiss army knife of systems administration. Secure Shell, also known as ssh, was developed in 1995 by Tau Ylonen after the University of Technology in Finland suffered a password sniffing attack. Back then it was common to use tools like rcp, rsh, ftp and telnet to connect to systems and move files across the network. The main problem with these tools is they provide no security and transmitted data in plain text including sensitive login credentials. SSH provides this security by encrypting all traffic transmitted over the wire to protect from password sniffing attacks. One of the more common use cases involving SSH is found when using scp. Secure Copy (scp) transmits data between hosts using SSH and allows you to easily copy all types of files. The syntax for the scp command is: scp /pathlocal/filenamelocal remoteuser@remotehost:/pathremote/filenameremote In the following simple example, I move a file named myfile from the system test1 to the system test2. I am prompted to provide valid user credentials for the remote host before the transfer will proceed.  If I were only using ftp, this information would be unencrypted as it went across the wire.  However, because scp uses SSH, my user credentials and the file and its contents are confidential and remain secure throughout the transfer.  [user1@test1 ~]# scp /home/user1/myfile user1@test2:/home/user1user1@test2's password: myfile                                    100%    0     0.0KB/s   00:00 You can also use ssh to send network traffic and utilize the encryption built into ssh to protect traffic over the wire. This is known as an ssh tunnel. In order to utilize this feature, the server that you intend to connect to (the remote system) must have TCP forwarding enabled within the sshd configuraton. To enable TCP forwarding on the remote system, make sure AllowTCPForwarding is set to yes and enabled in the /etc/ssh/sshd_conf file: AllowTcpForwarding yes Once you have this configured, you can connect to the server and setup a local port which you can direct traffic to that will go over the secure tunnel. The following command will setup a tunnel on port 8989 on your local system. You can then redirect a web browser to use this local port, allowing the traffic to go through the encrypted tunnel to the remote system. It is important to select a local port that is not being used by a service and is not restricted by firewall rules.  In the following example the -D specifies a local dynamic application level port forwarding and the -N specifies not to execute a remote command.   ssh –D 8989 [email protected] -N You can also forward specific ports on both the local and remote host. The following example will setup a port forward on port 8080 and forward it to port 80 on the remote machine. ssh -L 8080:farwebserver.com:80 [email protected] You can even run remote commands via ssh which is quite useful for scripting or remote system administration tasks. The following example shows how to  log in remotely and execute the command ls –la in the home directory of the machine. Because ssh encrypts the traffic, the login credentials and output of the command are completely protected while they travel over the wire. [rchase@test1 ~]$ ssh rchase@test2 'ls -la'rchase@test2's password: total 24drwx------  2 rchase rchase 4096 Sep  6 15:17 .drwxr-xr-x. 3 root   root   4096 Sep  6 15:16 ..-rw-------  1 rchase rchase   12 Sep  6 15:17 .bash_history-rw-r--r--  1 rchase rchase   18 Dec 20  2012 .bash_logout-rw-r--r--  1 rchase rchase  176 Dec 20  2012 .bash_profile-rw-r--r--  1 rchase rchase  124 Dec 20  2012 .bashrc You can execute any command contained in the quotations marks as long as you have permission with the user account that you are using to log in. This can be very powerful and useful for collecting information for reports, remote controlling systems and performing systems administration tasks using shell scripts. To make your shell scripts even more useful and to automate logins you can use ssh keys for running commands remotely and securely without the need to enter a password. You can accomplish this with key based authentication. The first step in setting up key based authentication is to generate a public key for the system that you wish to log in from. In the following example you are generating a ssh key on a test system. In case you are wondering, this key was generated on a test VM that was destroyed after this article. [rchase@test1 .ssh]$ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/rchase/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/rchase/.ssh/id_rsa.Your public key has been saved in /home/rchase/.ssh/id_rsa.pub.The key fingerprint is:7a:8e:86:ef:59:70:ef:43:b7:ee:33:03:6e:6f:69:e8 rchase@test1The key's randomart image is:+--[ RSA 2048]----+|                 ||  . .            ||   o .           ||    . o o        ||   o o oS+       ||  +   o.= =      ||   o ..o.+ =     ||    . .+. =      ||     ...Eo       |+-----------------+ Now that you have the key generated on the local system you should to copy it to the target server into a temporary location. The user’s home directory is fine for this. [rchase@test1 .ssh]$ scp id_rsa.pub rchase@test2:/home/rchaserchase@test2's password: id_rsa.pub                  Now that the file has been copied to the server, you need to append it to the authorized_keys file. This should be appended to the end of the file in the event that there are other authorized keys on the system. [rchase@test2 ~]$ cat id_rsa.pub >> .ssh/authorized_keys Once the process is complete you are ready to login. Since you are using key based authentication you are not prompted for a password when logging into the system.   [rchase@test1 ~]$ ssh test2Last login: Fri Sep  6 17:42:02 2013 from test1 This makes it much easier to run remote commands. Here’s an example of the remote command from earlier. With no password it’s almost as if the command ran locally. [rchase@test1 ~]$ ssh test2 'ls -la'total 32drwx------  3 rchase rchase 4096 Sep  6 17:40 .drwxr-xr-x. 3 root   root   4096 Sep  6 15:16 ..-rw-------  1 rchase rchase   12 Sep  6 15:17 .bash_history-rw-r--r--  1 rchase rchase   18 Dec 20  2012 .bash_logout-rw-r--r--  1 rchase rchase  176 Dec 20  2012 .bash_profile-rw-r--r--  1 rchase rchase  124 Dec 20  2012 .bashrc As a security consideration it's important to note the permissions of .ssh and the authorized_keys file.  .ssh should be 700 and authorized_keys should be set to 600.  This prevents unauthorized access to ssh keys from other users on the system.   An even easier way to move keys back and forth is to use ssh-copy-id. Instead of copying the file and appending it manually to the authorized_keys file, ssh-copy-id does both steps at once for you.  Here’s an example of moving the same key using ssh-copy-id.The –i in the example is so that we can specify the path to the id file, which in this case is /home/rchase/.ssh/id_rsa.pub [rchase@test1]$ ssh-copy-id -i /home/rchase/.ssh/id_rsa.pub rchase@test2 One of the last tips that I will cover is the ssh config file. By using the ssh config file you can setup host aliases to make logins to hosts with odd ports or long hostnames much easier and simpler to remember. Here’s an example entry in our .ssh/config file. Host dev1 Hostname somereallylonghostname.somereallylongdomain.com Port 28372 User somereallylongusername12345678 Let’s compare the login process between the two. Which would you want to type and remember? ssh somereallylongusername12345678@ somereallylonghostname.somereallylongdomain.com –p 28372 ssh dev1 I hope you find these tips useful.  There are a number of tools used by system administrators to streamline processes and simplify workflows and whether you are new to Linux or a longtime user, I'm sure you will agree that SSH offers useful features that can be used every day.  Send me your comments and let us know the ways you  use SSH with Linux.  If you have other tools you would like to see covered in a similar post, send in your suggestions.

• Raspberry Pi entrance signed backed by Umbraco - Part 1

  - by Chris Houston

  Being experts on all things Umbraco, we jumped at the chance to help our client, QV Offices, with their pressing signage predicament. They needed to display a sign in the entrance to their building and approached us for our advice. Of course it had to be electronic: displaying multiple names of their serviced office clients, meeting room bookings and on-the-pulse promotions. But with a winding Victorian staircase and minimal storage space how could the monitor be run, updated and managed? That’s where we came in…Raspberry PiUmbraco CMSAutomatic updatesAutomated monitor of the signPower saving when the screen is not in useMounting the screenThe screen that has been used is a standard LED low energy Full HD screen and has been mounted on the wall using it's VESA mounting points, as the wall is a stud wall we were able to add an access panel behind the screen to feed through the mains, HDMI and sensor cables.The Raspberry Pi is then tucked away out of sight in the main electrical cupboard which just happens to be next to the sign, we had an electrician add a power point inside this cupboard to allow us to power the screen and the Raspberry Pi.Designing the interface and editing the contentAlthough a room sign was the initial requirement from QV Offices, their medium term goal has always been to add online meeting booking to their website and hence we suggested adding information about the current and next day's meetings to the sign that would be pulled directly from their online booking system.We produced the design and built the web page to fit exactly on a 1920 x 1080 screen (Full HD in Portrait)As you would expect all the information can be edited via an Umbraco CMS, they are able to add floors, rooms, clients and virtual clients as well as add meeting bookings to their meeting diary.How we configured the Raspberry PiAfter receiving a new Raspberry Pi we downloaded the latest release of Raspbian operating system and followed the official guide which shows how to copy the OS onto an SD card from a Mac, we then followed the majority of steps on this useful guide: 10 Things to Do After Buying a Raspberry Pi.Installing ChromiumWe chose to use the Chromium web browser which for those who do not know is the open sourced version of Google Chrome. You can install this from the terminal with the following command:sudo apt-get install chromium-browserInstalling UnclutterWe found this little application which automatically hides the mouse pointer, it is used in the script below and is installed using the following command:sudo apt-get install unclutterAuto start Chromium and disabling the screen saver, power saving and mouseWhen the Raspberry Pi has been installed it will not have a keyboard or mouse and hence if their was a power cut we needed it to always boot and re-loaded Chromium with the correct URL.Our preferred command line text editor is Nano and I have assumed you know how to use this editor or will be able to work it out pretty quickly.So using the following command:sudo nano /etc/xdg/lxsession/LXDE/autostartWe then changed the autostart file content to:@lxpanel --profile LXDE@pcmanfm --desktop --profile LXDE@xscreensaver -no-splash@xset s off@xset -dpms@xset s noblank@chromium --kiosk --incognito http://www.qvoffices.com/someURL@unclutter -idle 0The first few commands turn off the screen saver and power saving, we then open Cromium in Kiosk Mode (full screen with no menu etc) and pass in the URL to use (I have changed the URL in this example) We found a useful blog post with the Cromium command line switches.Finally we also open an application called Unclutter which auto hides the mouse after 0 seconds, so you will never see a mouse on the sign.We also had to edit the following file:sudo nano /etc/lightdm/lightdm.confAnd added the following line under the [SeatDefault] section:xserver-command=X -s 0 dpmsRefreshing the screenWe decided to try and add a scheduled task that would trigger Chromium to reload the page, at some point in the future we might well change this to using Javascript to update the content, but for now this works fine.First we installed the XDOTool which enables you to script Keyboard commands:sudo apt-get install xdotoolWe used the Refreshing Chromium Browser by Shell Script post as a reference and created the following shell script (which we called refreshing.sh):export DISPLAY=":0"WID=$(xdotool search --onlyvisible --class chromium|head -1)xdotool windowactivate ${WID}xdotool key ctrl+F5This selects the correct display and then sends a CTRL + F5 to refresh Chromium.You will need to give this file execute permissions:chmod a=rwx refreshing.shNow we have the script file setup we just need to schedule it to call this script periodically which is done by using Crontab, to edit this you use the following command:crontab -eAnd we added the following:*/5 * * * * DISPLAY=":.0" /home/pi/scripts/refreshing.sh >/home/pi/cronlog.log 2>&1This calls our script every 5 minutes to refresh the display and it logs any errors to the cronlog.log file.SummaryQV Offices now have a richer and more manageable booking system than they did before we started, and a great new sign to boot.How could we make sure that the sign was running smoothly downstairs in a busy office centre? A second post will follow outlining exactly how Vizioz enabled QV Offices to monitor their sign simply and remotely, from the comfort of their desks.

In this blog series we will review an existing OpenStack setup using the Oracle OpenStack Tech Preview and explain the different network components through use cases and examples. The goal is to show how the different pieces come together and provide a bigger picture view of the network architecture in OpenStack. This can be very helpful to users making their first steps in OpenStack or anyone wishes to understand how networking works in this environment.  We will go through the basics first and build the examples as we go. According to the recent Icehouse user survey and the one before it, Neutron with Open vSwitch plug-in is the most widely used network setup both in production and in POCs (in terms of number of customers) and so in this blog series we will analyze this specific OpenStack networking setup. As we know there are many options to setup OpenStack networking and while Neturon + Open vSwitch is the most popular setup there is no claim that it is either best or the most efficient option. Neutron + Open vSwitch is an example, one which provides a good starting point for anyone interested in understanding OpenStack networking. Even if you are using different kind of network setup such as different Neutron plug-in or even not using Neutron at all this will still be a good starting point to understand the network architecture in OpenStack. The setup we are using for the examples is the one used in the Oracle OpenStack Tech Preview. Installing it is simple and it would be helpful to have it as reference. In this setup we use eth2 on all servers for VM network, all VM traffic will be flowing through this interface.The Oracle OpenStack Tech Preview is using VLANs for L2 isolation to provide tenant and network isolation. The following diagram shows how we have configured our deployment: This first post is a bit long and will focus on some basic concepts in OpenStack networking. The components we will be discussing are Open vSwitch, network namespaces, Linux bridge and veth pairs. Note that this is not meant to be a comprehensive review of these components, it is meant to describe the component as much as needed to understand OpenStack network architecture. All the components described here can be further explored using other resources. Open vSwitch (OVS) In the Oracle OpenStack Tech Preview OVS is used to connect virtual machines to the physical port (in our case eth2) as shown in the deployment diagram. OVS contains bridges and ports, the OVS bridges are different from the Linux bridge (controlled by the brctl command) which are also used in this setup. To get started let’s view the OVS structure, use the following command: # ovs-vsctl show 7ec51567-ab42-49e8-906d-b854309c9edf     Bridge br-int         Port br-int             Interface br-int type: internal         Port "int-br-eth2"             Interface "int-br-eth2"     Bridge "br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2" ovs_version: "1.11.0" We see a standard post deployment OVS on a compute node with two bridges and several ports hanging off of each of them. The example above is a compute node without any VMs, we can see that the physical port eth2 is connected to a bridge called “br-eth2”. We also see two ports "int-br-eth2" and "phy-br-eth2" which are actually a veth pair and form virtual wire between the two bridges, veth pairs are discussed later in this post. When a virtual machine is created a port is created on one the br-int bridge and this port is eventually connected to the virtual machine (we will discuss the exact connectivity later in the series). Here is how OVS looks after a VM was launched: # ovs-vsctl show efd98c87-dc62-422d-8f73-a68c2a14e73d     Bridge br-int         Port "int-br-eth2"             Interface "int-br-eth2"         Port br-int             Interface br-int type: internal         Port "qvocb64ea96-9f" tag: 1             Interface "qvocb64ea96-9f"     Bridge "br-eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2" ovs_version: "1.11.0" Bridge "br-int" now has a new port "qvocb64ea96-9f" which connects to the VM and tagged with VLAN 1. Every VM which will be launched will add a port on the “br-int” bridge for every network interface the VM has. Another useful command on OVS is dump-flows for example: # ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=735.544s, table=0, n_packets=70, n_bytes=9976, idle_age=17, priority=3,in_port=1,dl_vlan=1000 actions=mod_vlan_vid:1,NORMAL cookie=0x0, duration=76679.786s, table=0, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=2,in_port=1 actions=drop cookie=0x0, duration=76681.36s, table=0, n_packets=68, n_bytes=7950, idle_age=17, hard_age=65534, priority=1 actions=NORMAL As we see the port which is connected to the VM has the VLAN tag 1. However the port on the VM network (eth2) will be using tag 1000. OVS is modifying the vlan as the packet flow from the VM to the physical interface. In OpenStack the Open vSwitch agent takes care of programming the flows in Open vSwitch so the users do not have to deal with this at all. If you wish to learn more about how to program the Open vSwitch you can read more about it at http://openvswitch.org looking at the documentation describing the ovs-ofctl command. Network Namespaces (netns) Network namespaces is a very cool Linux feature can be used for many purposes and is heavily used in OpenStack networking. Network namespaces are isolated containers which can hold a network configuration and is not seen from outside of the namespace. A network namespace can be used to encapsulate specific network functionality or provide a network service in isolation as well as simply help to organize a complicated network setup. Using the Oracle OpenStack Tech Preview we are using the latest Unbreakable Enterprise Kernel R3 (UEK3), this kernel provides a complete support for netns. Let's see how namespaces work through couple of examples to control network namespaces we use the ip netns command: Defining a new namespace: # ip netns add my-ns # ip netns list my-ns As mentioned the namespace is an isolated container, we can perform all the normal actions in the namespace context using the exec command for example running the ifconfig command: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:16436 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) We can run every command in the namespace context, this is especially useful for debug using tcpdump command, we can ping or ssh or define iptables all within the namespace. Connecting the namespace to the outside world: There are various ways to connect into a namespaces and between namespaces we will focus on how this is done in OpenStack. OpenStack uses a combination of Open vSwitch and network namespaces. OVS defines the interfaces and then we can add those interfaces to namespace. So first let's add a bridge to OVS: # ovs-vsctl add-br my-bridge Now let's add a port on the OVS and make it internal: # ovs-vsctl add-port my-bridge my-port # ovs-vsctl set Interface my-port type=internal And let's connect it into the namespace: # ip link set my-port netns my-ns Looking inside the namespace: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:65536 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) my-port   Link encap:Ethernet HWaddr 22:04:45:E2:85:21           BROADCAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) Now we can add more ports to the OVS bridge and connect it to other namespaces or other device like physical interfaces. Neutron is using network namespaces to implement network services such as DCHP, routing, gateway, firewall, load balance and more. In the next post we will go into this in further details. Linux Bridge and veth pairs Linux bridge is used to connect the port from OVS to the VM. Every port goes from the OVS bridge to a Linux bridge and from there to the VM. The reason for using regular Linux bridges is for security groups’ enforcement. Security groups are implemented using iptables and iptables can only be applied to Linux bridges and not to OVS bridges. Veth pairs are used extensively throughout the network setup in OpenStack and are also a good tool to debug a network problem. Veth pairs are simply a virtual wire and so veths always come in pairs. Typically one side of the veth pair will connect to a bridge and the other side to another bridge or simply left as a usable interface. In this example we will create some veth pairs, connect them to bridges and test connectivity. This example is using regular Linux server and not an OpenStack node: Creating a veth pair, note that we define names for both ends: # ip link add veth0 type veth peer name veth1 # ifconfig -a . . veth0     Link encap:Ethernet HWaddr 5E:2C:E6:03:D0:17           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) veth1     Link encap:Ethernet HWaddr E6:B6:E2:6D:42:B8           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) . . To make the example more meaningful this we will create the following setup: veth0 => veth1 => br-eth3 => eth3 ======> eth2 on another Linux server br-eth3 – a regular Linux bridge which will be connected to veth1 and eth3 eth3 – a physical interface with no IP on it, connected to a private network eth2 – a physical interface on the remote Linux box connected to the private network and configured with the IP of 50.50.50.1 Once we create the setup we will ping 50.50.50.1 (the remote IP) through veth0 to test that the connection is up: # brctl addbr br-eth3 # brctl addif br-eth3 eth3 # brctl addif br-eth3 veth1 # brctl show bridge name     bridge id               STP enabled     interfaces br-eth3         8000.00505682e7f6       no              eth3                                                         veth1 # ifconfig veth0 50.50.50.50 # ping -I veth0 50.50.50.51 PING 50.50.50.51 (50.50.50.51) from 50.50.50.50 veth0: 56(84) bytes of data. 64 bytes from 50.50.50.51: icmp_seq=1 ttl=64 time=0.454 ms 64 bytes from 50.50.50.51: icmp_seq=2 ttl=64 time=0.298 ms When the naming is not as obvious as the previous example and we don't know who are the paired veth interfaces we can use the ethtool command to figure this out. The ethtool command returns an index we can look up using ip link command, for example: # ethtool -S veth1 NIC statistics: peer_ifindex: 12 # ip link . . 12: veth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 Summary That’s all for now, we quickly reviewed OVS, network namespaces, Linux bridges and veth pairs. These components are heavily used in the OpenStack network architecture we are exploring and understanding them well will be very useful when reviewing the different use cases. In the next post we will look at how the OpenStack network is laid out connecting the virtual machines to each other and to the external world. @RonenKofman

• Why do I recieve multiple warnings of "No running instance of xfce4-panel was found" when logging into Xubuntu?

  - by Fredrik

  I'm running Xubuntu 11.04, the bootup-time is quite fast but when I log in it takes close to a minute before the desktop is displayed, meanwhile I see no activity on the hard drive. When I finally have the desktop I see this notification repeated 10 times: and then this one: In .config/autostart I have these entries $ ls xfce4-settings-helper-autostart.desktop xfce4-clipman-plugin-autostart.desktop xfce-panel.desktop $ cat xfce-panel.desktop [Desktop Entry] Encoding=UTF-8 Version=0.9.4 Type=Application Name=xfce4-panel Comment= Exec=xfce4-panel StartupNotify=false Terminal=false Hidden=false I need some assistance to locate the slow startup, which logs to look at etc. And then this annoying message about xfce-panel. Where do I look for from where it is started.

• Why does Ubuntu refuse to execute files from an NTFS partition?

  - by Ivan

  I mount an NTFS partition (where I've got some Linux binaries and scripts alongside with Win32 and data files) with the following fstab line: /dev/sda5 /mnt/dat ntfs-3g rw,dev,exec,auto,async,users,umask=000,uid=1000,gid=1000,locale=en_US.utf8, errors=remount-ro 0 0 All files seem to have executable attribute set then, but if I try to actually execute them, I get "Permission denied" error. Even with sudo. Even while execute (as well as read and write) permissions are granted to everyone and all the files owner is set to the user. So how do I set the system up to be able to run Linux binaries from NTFS?

• It&rsquo;s A Team Sport: PASS Board Year 2, Q3

  - by Denise McInerney

  As I type this I’m on an airplane en route to my 12th PASS Summit. It’s been a very busy 3.5 months since my last post on my work as a Board member. Nearing the end of my 2-year term I am struck by how much has happened, and yet how fast the time has gone. But I’ll save the retrospective post for next time and today focus on what happened in Q3. In the last three months we made progress on several fronts, thanks to the contributions of many volunteers and HQ staff members. They deserve our appreciation for their dedication to delivering for the membership week after week. Virtual Chapters The Virtual Chapters continue to provide many PASS members with valuable free training. Between July and September of 2013 VCs hosted over 50 webinars with a total of 4300 attendees. This quarter also saw the launch of the Security & Global Russian VCs. Both are off to a strong start and I welcome these additions to the Virtual Chapter portfolio. At the beginning of 2012 we had 14 Virtual Chapters. Today we have 22. This growth has been exciting to see. It has also created a need to have more volunteers help manage the work of the VCs year-round. We have renewed focus on having Virtual Chapter Mentors work with the VC Leaders and other volunteers. I am grateful to volunteers Julie Koesmarno, Thomas LeBlanc and Marcus Bittencourt who join original VC Mentor Steve Simon on this team. Thank you for stepping up to help. Many improvements to the VC web sites have been rolling out over the past few weeks. Our marketing and IT teams have been busy working a new look-and-feel, features and a logo for each VC. They have given the VCs a fresh, professional look consistent with the rest of the PASS branding, and all VCs now have a logo that connects to PASS and the particular focus of the chapter. 24 Hours of PASS The Summit Preview edition  of 24HOP was held on July 31 and by all accounts was a success. Our first use of the GoToWebinar platform for this event went extremely well. Thanks to our speakers, moderators and sponsors for making this event possible. Special thanks to HQ staffers Vicki Van Damme and Jane Duffy for a smoothly run event. Coming up: the 24HOP Portuguese Edition will be held November 13-14, followed December 12-13 by the Spanish Edition. Thanks to the Portuguese- and Spanish-speaking community volunteers who are organizing these events. July Board Meeting The Board met July 18-19 in Kansas City. The first order of business was the election of the Executive Committee who will take office January 1. I was elected Vice President of Marketing and will join incoming President Thomas LaRock, incoming Executive Vice President of Finance Adam Jorgensen and Immediate Past President Bill Graziano on the Exec Co. I am honored that my fellow Board members elected me to this position and look forward to serving the organization in this role. Visit to PASS HQ In late September I traveled to Vancouver for my first visit to PASS HQ, where I joined Tom LaRock and Adam Jorgensen to make plans for 2014.  Our visit was just a few weeks before PASS Summit and coincided with the Board election, and the office was humming with activity. I saw first-hand the enthusiasm and dedication of everyone there. In each interaction I observed a focus on what is best for PASS and our members. Our partners at HQ are key to the organization’s success. This week at PASS Summit is a great opportunity for all of us to remember that, and say “thanks.” Next Up PASS Summit—of course! I’ll be around all week and look forward to connecting with many of our member over meals, at the Community Zone and between sessions. In the evenings you can find me at the Welcome Reception, Exhibitor’s Reception and Community Appreciation Party. And I will be at the Board Q&A session  Friday at 12:45 p.m. Transitions The newly elected Exec Co and Board members take office January 1, and the Virtual Chapter portfolio is transitioning to a new director. I’m thrilled that Jen Stirrup will be taking over. Jen has experience as a volunteer and co-leader of the Business Intelligence Virtual Chapter and was a key contributor to the BI VCs expansion to serving our members in the EMEA region. I’ll be working closely with Jen over the next couple of months to ensure a smooth transition.

• How to Restore the Real Internet Explorer Desktop Icon in Windows 7

  - by The Geek

  Remember how previous versions of Windows had an Internet Explorer icon on the desktop, and you could right-click it to quickly access the Internet Options screen? It’s completely gone in Windows 7, but a geeky hack can bring it back. Microsoft removed this feature to comply with all those murky legal battles they’ve had, and their alternate suggestion is to create a standard shortcut to iexplore.exe on the Desktop, but it’s not the same thing. We’ve got a registry hack to bring it back. This guest article was written by Ramesh from the WinHelpOnline blog, where he’s got loads of really geeky registry hacks. Bring Back the Internet Explorer Namespace Icon in Windows 7 the Easy Way If you just want the IE icon back, all you need to do is download the RealInternetExplorerIcon.zip file, extract the contents, and then double-click on the w7_ie_icon_restore.reg file. That’s all you have to do. There’s also an undo registry file there if you want to get rid of it. Download the Real Internet Explorer Icon Registry Hack Manual Registry Hack If you prefer doing things the manual way, or just really want to understand how this hack works, you can follow through the manual steps below to learn how it was done, but we’ll have to warn you that it’s a lot of steps. Launch Regedit.exe using the Start Menu search box, and then navigate to the following location: HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30309D} Right-click on the key on the left-hand pane, choose Export, and save it to a .REG file (say, ie-guid.reg) Open up the REG file using Notepad… From the Edit menu, click Replace, and replace every occurrence of the following GUID string {871C5380-42A0-1069-A2EA-08002B30309D} … with a custom GUID string, such as: {871C5380-42A0-1069-A2EA-08002B30301D} Save the REG file and close Notepad, and then double-click on the file to merge the contents to the registry. Either re-open the registry editor, or use the F5 key to reload everything with the new changes (this step is important). Now you can navigate downto the following registry key: HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30301D} \ Shellex \ ContextMenuHandlers \ ieframe Double-click on the (default) key in the right-hand pane and set its data as: {871C5380-42A0-1069-A2EA-08002B30309D} With this done, press F5 on the desktop and you’ll see the Internet Explorer icon that looks like this: The icon appears incomplete without the Properties command in right click menu, so keep reading. Final Registry Hack Adjustments Click on the following key, which should still be viewable in your Registry editor window from the last step. HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30301D} Double-click LocalizedString in the right-hand pane and type the following data to rename the icon. Internet Explorer Select the following key: HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30301D}\shell Add a subkey and name it as Properties, then select the Properties key, double-click the (default) value and type the following: P&roperties Create a String value named Position, and type the following data bottom At this point the window should look something like this: Under Properties, create a subkey and name it as Command, and then set its (default) value as follows: control.exe inetcpl.cpl Navigate down to the following key, and then delete the value named LegacyDisable HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30301D} \ shell \ OpenHomePage Now head to the this key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Desktop \ NameSpace Create a subkey named {871C5380-42A0-1069-A2EA-08002B30301D} (which is the custom GUID that we used earlier in this article.) Press F5 to refresh the Desktop, and here is how the Internet Explorer icon would look like, finally. That’s it! It only took 24 steps, but you made it through to the end—of course, you could just download the registry hack and get the icon back with a double-click.

It looks like it's perhaps a bug? or I don't know. I simply installed 32-bit version of Ubuntu in VirtualBox and converted package there. For some reason I couldn't convert 32-bit package in 64 OS. and that is that. If someone ever finds the reason ffor this behavior - plz. post somewhere in comments. Thanks

• Why do we need fork to create new process

  - by user3671483

  In Unix whenever we want to create a new process, we fork the current process i.e. we create a new child process which is exactly the same as the parent process and then we do exec system call to replace the child process with a new process i.e. we replace all the data for the parent process eith that for the new process. Why do we create a copy of the parent process in the first place and why don't we create a new process directly? I am new to Unix please explain in lay-man terms.

• Typing commands into a terminal always returns "-bash: /usr/bin/python: is a directory"

  - by Artur Sapek

  I think I messed something up on my Ubuntu server while trying to upgrade to Python 2.7.2. Every time I type in a command that doesn't have a response, the default from bash is this: -bash: /usr/bin/python: is a directory Just like it would say if I typed the name of a directory. But this happens every time I enter a command that doesn't do anything. artur@SERVER:~$ dslkfjdsklfdshjk -bash: /usr/bin/python: is a directory I remember messing with the update-alternatives to point at python at some point, perhaps that could be it? Any inklings as to why this is happening? Related to this problem is also the fact that when I try using easy_install it tells me -bash: /usr/bin/easy_install: /usr/bin/python: bad interpeter: Permission denied /etc/fstab/ is set to exec. I've read that could fix the second problem but it hasn't.

• Why does my Perl CGI script raise an internal server error on Apache?

  - by itcplpl

  I've installed apache2 on Ubuntu 11.04, and localhost is working. I created a simple printenv.pl script and put it in the following directory $ mv printenv.pl /usr/lib/cgi-bin/ $ chmod +rx /usr/lib/cgi-bin/printenv.pl However when I go to http://127.0.0.1/cgi-bin/printenv.pl, I get a 500 Internal Server Error I checked the error log at /var/log/apache2, and this is what it says: [Mon Oct 24 11:04:25 2011] [error] (13)Permission denied: exec of '/usr/lib/cgi-bin/printenv.pl' failed [Mon Oct 24 11:04:25 2011] [error] [client 127.0.0.1] Premature end of script headers: printenv.pl Any suggestions on how I can fix this and run CGI scripts on my localhost?
