  • nginx + apache subdomain redirection fault

    - by webwolf
    i really need your advice folks since i'm experiencing some troubles with nginx & apache2 subdomains configs first of all, there's a site (say, site.com) and two subdomains (links.site.com and shop.site.com) whose files are physically located at the same level of FS hierarchy as the site.com itself my hoster has configured both apache and nginx by my request, but it still doesn't work as it used to both of subdomains point to the main page of site.com for some unknown and implicit (for me) reason :( my assumption is that's happen because site.com record is placed first in both configs?!.. please help me solve this out! every opinion would be appreciated =) nginx.conf: server { listen 95.169.187.234:80; server_name site.com www.site.com ; access_log /home/www/site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 95.169.187.234:80; server_name links.site.com www.links.site.com ; access_log /home/www/links.site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/links.site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 95.169.187.234:80; server_name shop.site.com www.shop.site.com ; access_log /home/www/shop.site.com/logs/nginx.access.log main; location ~* ^.+\.(jpeg|jpg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|swf|avi|mp3|mpg|mpeg|asf|vmw)$ { expires 30d; root /home/www/shop.site.com/www; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # location ~ /\.ht { deny all; } location / { set $referer $http_referer; proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Referer $referer; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 64k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } httpd.conf: # ServerRoot "/usr/local/apache2" PidFile /var/run/httpd.pid Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 15 Listen 127.0.0.1:8080 NameVirtualHost 127.0.0.1:8080 ... #Listen *:80 NameVirtualHost *:80 ServerName www.site.com ServerAlias site.com UseCanonicalName Off CustomLog /home/www/site.com/logs/custom_log combined ErrorLog /home/www/site.com/logs/error_log DocumentRoot /home/www/site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php ServerName www.links.site.com ServerAlias links.site.com UseCanonicalName Off CustomLog /home/www/links.site.com/logs/custom_log combined ErrorLog /home/www/links.site.com/logs/error_log DocumentRoot /home/www/links.site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php ServerName www.shop.site.com ServerAlias shop.site.com UseCanonicalName Off CustomLog /home/www/shop.site.com/logs/custom_log combined ErrorLog /home/www/shop.site.com/logs/error_log DocumentRoot /home/www/shop.site.com/www AllowOverride All Options +FollowSymLinks Options -MultiViews Options -Indexes Options Includes Order allow,deny Allow from all DirectoryIndex index.html index.htm index.php # if DSO load module first: LoadModule rpaf_module modules/mod_rpaf-2.0.so RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 RPAFheader X-Forwarded-For Include conf/virthost/*.conf

    I use multiple browser many times when I am working with multiple projects simultaneously. Often I use Google Reader to read few feeds. Recently, I faced the following error and this error will not go. I even restarted my computer and rebooted my network. I am confident that my computer does not have viruses or malware, I could not tackle this error. When I opened Google Reader on another browser, it worked fine. Finally, I found the solution and I want share it with all of you. Error We’re sorry… … but your computer or network may be sending automated queries. To protect our users, we can’t process your request right now. I removed the cookies of Google Reader with the name ‘reader_offline’ as displayed in image below. Once I remove the above mentioned cookie, I could login perfectly fine in Google Reader. I think this message from Google was misleading and inaccurate; however, the solution is easy enough. I just wanted to share this quick tip with everyone who is facing such an issue.

  • Installing a DHCP Service On Win2k8 ( Windows Server 2008 )

    - by Akshay Deep Lamba
    Introduction Dynamic Host Configuration Protocol (DHCP) is a core infrastructure service on any network that provides IP addressing and DNS server information to PC clients and any other device. DHCP is used so that you do not have to statically assign IP addresses to every device on your network and manage the issues that static IP addressing can create. More and more, DHCP is being expanded to fit into new network services like the Windows Health Service and Network Access Protection (NAP). However, before you can use it for more advanced services, you need to first install it and configure the basics. Let’s learn how to do that. Installing Windows Server 2008 DHCP Server Installing Windows Server 2008 DCHP Server is easy. DHCP Server is now a “role” of Windows Server 2008 – not a windows component as it was in the past. To do this, you will need a Windows Server 2008 system already installed and configured with a static IP address. You will need to know your network’s IP address range, the range of IP addresses you will want to hand out to your PC clients, your DNS server IP addresses, and your default gateway. Additionally, you will want to have a plan for all subnets involved, what scopes you will want to define, and what exclusions you will want to create. To start the DHCP installation process, you can click Add Roles from the Initial Configuration Tasks window or from Server Manager à Roles à Add Roles. Figure 1: Adding a new Role in Windows Server 2008 When the Add Roles Wizard comes up, you can click Next on that screen. Next, select that you want to add the DHCP Server Role, and click Next. Figure 2: Selecting the DHCP Server Role If you do not have a static IP address assigned on your server, you will get a warning that you should not install DHCP with a dynamic IP address. At this point, you will begin being prompted for IP network information, scope information, and DNS information. If you only want to install DHCP server with no configured scopes or settings, you can just click Next through these questions and proceed with the installation. On the other hand, you can optionally configure your DHCP Server during this part of the installation. In my case, I chose to take this opportunity to configure some basic IP settings and configure my first DHCP Scope. I was shown my network connection binding and asked to verify it, like this: Figure 3: Network connection binding What the wizard is asking is, “what interface do you want to provide DHCP services on?” I took the default and clicked Next. Next, I entered my Parent Domain, Primary DNS Server, and Alternate DNS Server (as you see below) and clicked Next. Figure 4: Entering domain and DNS information I opted NOT to use WINS on my network and I clicked Next. Then, I was promoted to configure a DHCP scope for the new DHCP Server. I have opted to configure an IP address range of 192.168.1.50-100 to cover the 25+ PC Clients on my local network. To do this, I clicked Add to add a new scope. As you see below, I named the Scope WBC-Local, configured the starting and ending IP addresses of 192.168.1.50-192.168.1.100, subnet mask of 255.255.255.0, default gateway of 192.168.1.1, type of subnet (wired), and activated the scope. Figure 5: Adding a new DHCP Scope Back in the Add Scope screen, I clicked Next to add the new scope (once the DHCP Server is installed). I chose to Disable DHCPv6 stateless mode for this server and clicked Next. Then, I confirmed my DHCP Installation Selections (on the screen below) and clicked Install. Figure 6: Confirm Installation Selections After only a few seconds, the DHCP Server was installed and I saw the window, below: Figure 7: Windows Server 2008 DHCP Server Installation succeeded I clicked Close to close the installer window, then moved on to how to manage my new DHCP Server. How to Manage your new Windows Server 2008 DHCP Server Like the installation, managing Windows Server 2008 DHCP Server is also easy. Back in my Windows Server 2008 Server Manager, under Roles, I clicked on the new DHCP Server entry. Figure 8: DHCP Server management in Server Manager While I cannot manage the DHCP Server scopes and clients from here, what I can do is to manage what events, services, and resources are related to the DHCP Server installation. Thus, this is a good place to go to check the status of the DHCP Server and what events have happened around it. However, to really configure the DHCP Server and see what clients have obtained IP addresses, I need to go to the DHCP Server MMC. To do this, I went to Start à Administrative Tools à DHCP Server, like this: Figure 9: Starting the DHCP Server MMC When expanded out, the MMC offers a lot of features. Here is what it looks like: Figure 10: The Windows Server 2008 DHCP Server MMC The DHCP Server MMC offers IPv4 & IPv6 DHCP Server info including all scopes, pools, leases, reservations, scope options, and server options. If I go into the address pool and the scope options, I can see that the configuration we made when we installed the DHCP Server did, indeed, work. The scope IP address range is there, and so are the DNS Server & default gateway. Figure 11: DHCP Server Address Pool Figure 12: DHCP Server Scope Options So how do we know that this really works if we do not test it? The answer is that we do not. Now, let’s test to make sure it works. How do we test our Windows Server 2008 DHCP Server? To test this, I have a Windows Vista PC Client on the same network segment as the Windows Server 2008 DHCP server. To be safe, I have no other devices on this network segment. I did an IPCONFIG /RELEASE then an IPCONFIG /RENEW and verified that I received an IP address from the new DHCP server, as you can see below: Figure 13: Vista client received IP address from new DHCP Server Also, I went to my Windows 2008 Server and verified that the new Vista client was listed as a client on the DHCP server. This did indeed check out, as you can see below: Figure 14: Win 2008 DHCP Server has the Vista client listed under Address Leases With that, I knew that I had a working configuration and we are done!

  • Creating an SMF service for mercurial web server

    - by Chris W Beal
    I'm working on a project at the moment, which has a number of contributers. We're managing the project gate (which is stand alone) with mercurial. We want to have an easy way of seeing the changelog, so we can show management what is going on.  Luckily mercurial provides a basic web server which allows you to see the changes, and drill in to change sets. This can be run as a daemon, but as it was running on our build server, every time it was rebooted, someone needed to remember to start the process again. This is of course a classic usage of SMF. Now I'm not an experienced person at writing SMF services, so it took me 1/2 an hour or so to figure it out the first time. But going forward I should know what I'm doing a bit better. I did reference this doc extensively. Taking a step back, the command to start the mercurial web server is $ hg serve -p <port number> -d So we somehow need to get SMF to run that command for us. In the simplest form, SMF services are really made up of two components. The manifest Usually lives in /var/svc/manifest somewhere Can be imported from any location The method Usually live in /lib/svc/method I simply put the script straight in that directory. Not very repeatable, but it worked Can take an argument of start, stop, or refresh Lets start with the manifest. This looks pretty complex, but all it's doing is describing the service name, the dependencies, the start and stop methods, and some properties. The properties can be by instance, that is to say I could have multiple hg serve processes handling different mercurial projects, on different ports simultaneously Here is the manifest I wrote. I stole extensively from the examples in the Documentation. So my manifest looks like this $ cat hg-serve.xml <?xml version="1.0"?> <!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1"> <service_bundle type='manifest' name='hg-serve'> <service name='application/network/hg-serve' type='service' version='1'> <dependency name='network' grouping='require_all' restart_on='none' type='service'> <service_fmri value='svc:/milestone/network:default' /> </dependency> <exec_method type='method' name='start' exec='/lib/svc/method/hg-serve %m' timeout_seconds='2' /> <exec_method type='method' name='stop' exec=':kill' timeout_seconds='2'> </exec_method> <instance name='project-gate' enabled='true'> <method_context> <method_credential user='root' group='root' /> </method_context> <property_group name='hg-serve' type='application'> <propval name='path' type='astring' value='/src/project-gate'/> <propval name='port' type='astring' value='9998' /> </property_group> </instance> <stability value='Evolving' /> <template> <common_name> <loctext xml:lang='C'>hg-serve</loctext> </common_name> <documentation> <manpage title='hg' section='1' /> </documentation> </template> </service> </service_bundle> So the only things I had to decide on in this are the service name "application/network/hg-serve" the start and stop methods (more of which later) and the properties. This is the information I need to pass to the start method script. In my case the port I want to start the web server on "9998", and the path to the source gate "/src/project-gate". These can be read in to the start method. So now lets look at the method scripts $ cat /lib/svc/method/hg-serve #!/sbin/sh # # # Copyright (c) 2012, Oracle and/or its affiliates. All rights reserved. # # Standard prolog # . /lib/svc/share/smf_include.sh if [ -z $SMF_FMRI ]; then echo "SMF framework variables are not initialized." exit $SMF_EXIT_ERR fi # # Build the command line flags # # Get the port and directory from the SMF properties port=`svcprop -c -p hg-serve/port $SMF_FMRI` dir=`svcprop -c -p hg-serve/path $SMF_FMRI` echo "$1" case "$1" in 'start') cd $dir /usr/bin/hg serve -d -p $port ;; *) echo "Usage: $0 {start|refresh|stop}" exit 1 ;; esac exit $SMF_EXIT_OK This is all pretty self explanatory, we read the port and directory using svcprop, and use those simply to run a command in the start case. We don't need to implement a stop case, as the manifest says to use "exec=':kill'for the stop method. Now all we need to do is import the manifest and start the service, but first verify the manifest # svccfg verify /path/to/hg-serve.xml If that doesn't give an error try importing it # svccfg import /path/to/hg-serve.xml If like me you originally put the hg-serve.xml file in /var/svc/manifest somewhere you'll get an error and told to restart the import service svccfg: Restarting svc:/system/manifest-import The manifest being imported is from a standard location and should be imported with the command : svcadm restart svc:/system/manifest-import # svcadm restart svc:/system/manifest-import and you're nearly done. You can look at the service using svcs -l # svcs -l hg-serve fmri svc:/application/network/hg-serve:project-gate name hg-serve enabled false state disabled next_state none state_time Thu May 31 16:11:47 2012 logfile /var/svc/log/application-network-hg-serve:project-gate.log restarter svc:/system/svc/restarter:default contract_id 15749 manifest /var/svc/manifest/network/hg/hg-serve.xml dependency require_all/none svc:/milestone/network:default (online) And look at the interesting properties # svcprop hg-serve hg-serve/path astring /src/project-gate hg-serve/port astring 9998 ...stuff deleted.... Then simply enable the service and if every things gone right, you can point your browser at http://server:9998 and get a nice graphical log of project activity. # svcadm enable hg-serve # svcs -l hg-serve fmri svc:/application/network/hg-serve:project-gate name hg-serve enabled true state online next_state none state_time Thu May 31 16:18:11 2012 logfile /var/svc/log/application-network-hg-serve:project-gate.log restarter svc:/system/svc/restarter:default contract_id 15858 manifest /var/svc/manifest/network/hg/hg-serve.xml dependency require_all/none svc:/milestone/network:default (online) None of this is rocket science, but a bit fiddly. Hence I thought I'd blog it. It might just be you see this in google and it clicks with you more than one of the many other blogs or how tos about it. Plus I can always refer back to it myself in 3 weeks, when I want to add another project to the server, and I've forgotten how to do it.

  • debootstrap or virt-install Ubuntu Server Maverick fails

    - by poelinca
    Oki so running any kind of variation of debootsrap i get the following error I: Extracting zlib1g... W: Failure trying to run: chroot /lxc/iso/dodo mount -t proc proc /proc debootstrap.log : mount: permission denied if i manualy chroot into the directory then i get promted with: id: cannot find name for group ID 0 I have no name!@...# i tryed addgroup but it's not installed , apt-get/aptitude : command not found , so i can't do anything with it . I've tryed ubuntu-vm-builder but since it's calling debootstrap i get the same error . Played with it for a few days and then i stoped and gaved virt-install a try , everithing works till i get to the console to finish the install witch shows only : Escape character is ^] and nothing more , no matter what i type . So basicly what i'm trying to do is build a usable chroot system so i can use it with lxc or libvirt . What are my options to get containers/virtualisation up and running ? I've read somewhere that i can use openvz templates with lxc or libvirt ? but how ? Let me know if you need aditional info ( p.s. doing all this on a dedicated server so i can't access it by hand , only ssh , plus on my local pc running ubuntu desktop maverick everithing works ) . EDIT Getting closer , i managed to understand how to use an openvz template with lxc , now the problem comes with the network bridge lxc-start: invalid interface name: br0 # Use same bridge device used in your controlling host setup lxc-start: failed to process 'lxc.network.link = br0 # Use same bridge device used in your controlling host setup ' lxc-start: failed to read configuration file i followed the exact steps to create a bridge and lxc conf looks like: lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 # Use same bridge device used in your controlling host setup lxc.network.hwaddr = {a1:b2:c3:d4:e5:f6} # As appropiate (line only needed if you wish to dhcp later) lxc.network.ipv4 = {10.0.0.100} # (Use 0.0.0.0 if you wish to dhcp later) lxc.network.name = eth0 # could likely be whatever you want Since it's not working i know smth is wrong so could somebody guyde me ? EDIT , looks like the base install was using an custom kernel ( bzImage-2.6.34.6-xxxx-grs-ipv6-65 ) for witch you i didn't found the headers , i did a update-grub after i installed a new kernel , edited menu.lst and no it's using 2.6.35-23-server and now debootstrap is working just fine same as ubuntu-vm-builder .

  • Setting MTU on Exalogic

    - by csoto
    For many reasons, a system administrator may want to change the MTU settings of a server. But in a system like Exalogic which contains lots of interconnected nodes and other various components, it's important to understand how this applies to the different networks. For example, when bringing up bonding of InfiniBand an error like the following may be thrown: Bringing up interface bond1: SIOCSIFMTU: Invalid argument Both scripts ifcfg-ib0 and ifcfg-ib1 (from the /etc/sysconfig/network-scripts/ direectory) have MTU set to 65500, which is a valid MTU value only if all IPoIB slaves operate in connected mode and are configured with the same value, so the line below must be added to both network scripts and then restart the network: CONNECTED_MODE=yes By the way, an error of the form “SIOCSIFMTU: Invalid argument” indicates that the requested MTU was rejected by the kernel. Typically this would be due to it exceeding the maximum value supported by the interface hardware. In that case you must either reduce the MTU to a value that is supported or obtain more capable hardware. This problem has been seen when trying to modify the MTU using the ifconfig command, like the output of the example below: [root@elxxcnxx ~]# ifconfig ib1 mtu 65520 SIOCSIFMTU: Invalid argument It's important to insist that in most cases the nodes must be rebooted after the MTU size has been changed. Although in some circumstances it may work without a reboot, it is not how it is typically documented. Now, in order to achieve a reduced memory consumption and improve performance for network traffic received on IPoIB related interfaces, it is recommend to reduce the MTU value in interface configuration files for IPoIB related bonds from 65520 to 64000. The change needs to be made to interface configuration files under the /etc/sysconfig/network-scripts directory and applies to the interface configuration files for bonds over IPoIB related slave devices, for example /etc/sysconfig/network-scripts/ifcfg-bond1. However, keep in mind that the numeric portion of the interface filenames that corresponding to IPoIB interfaces is expected to vary across compute nodes and vServers and so cannot be relied upon to identify which interface files are for bonds are over IPoIB rather than EoIB related slave interfaces. To fix these MTU values to the recommended settings, there are very useful instructions and a script on the MOS Note 1624434.1, and it's applicable physical and virtual configurations of Exalogic. Regarding the recommended MTU value for EoIB related interfaces, its maximum appropriate value is 1500. If for some reason a vServer has been created with a higher value (set on the /etc/sysconfig/network-scripts/ifcfg-bond0 file), then it must be fixed. An error like the following could be thrown under this circumstance: [root@vServer ~]# service network restart ... Bringing up interface bond0:  SIOCSIFMTU: Invalid argument Also an error like the one below can be seen on the /var/log/messages file of the vServer: kernel: T5074835532 [mlx4_vnic] eth1:vnic_change_mtu:360: failed: new_mtu 64000 2026 The MOS Note 1611657.1 is very useful for this purpose.

  • Wifi problems after upgrading to 13.10

    - by Simon
    I just upgraded to Ubuntu 13.10, but since the upgrade I don't have internet access via wifi anymore. I can: See networks Connect to a network Ping myself (localhost, 192.168.0.103) I can't: Ping others (including other devices on the same wireless network, including the gateway/router) Resolve hosts Access any other external resource, whether on my own network or on the internet Using Wireshark, I noticed my computer is continuously sending ARP-requests like "Who has 192.168.0.1 [which is the gateway]? Tell 192.168.0.103". It doesn't get any replies though. When I ping another IP-address for which it knows the mac-address (from cache), it turns out a packet loss of 90% occurs, and even if a packet manages to arrive it takes around 3000ms. The output of route -n is: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 9 0 0 eth1 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 Before upgrading, wifi worked fine. Using other devices, wifi still works fine.Resetting the router didn't help. Ethernet still works after upgrading. Any suggestions? Update: I'm using the wl driver. Here's the relevant output of some commands: lspci | grep Wireless 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01) cat /etc/modprobe.d/blacklist.conf [...] blacklist mac80211 blacklist brcm80211 blacklist cfg80211 blacklist lib80211_crypt_tkip blacklist lib80211 blacklist b43 cat /etc/rc.local sudo modprobe -r lib80211 sudo insmod /lib/modules/3.2.0-30-generic-pae/kernel/net/wireless/lib80211.ko sudo insmod /lib/modules/3.2.0-30-generic-pae/kernel/net/wireless/lib80211_crypt_wep.ko sudo insmod /lib/modules/3.2.0-30-generic-pae/kernel/net/wireless/lib80211_crypt_tkip.ko sudo insmod /lib/modules/3.2.0-30-generic-pae/kernel/net/wireless/lib80211_crypt_ccmp.ko sudo modprobe wl exit 0 The last lines are probably how I got wireless working after the previous upgrade (wireless has been a problem after each upgrade). Update 2: added information about the exact hardware below. The hardware is an integrated device, so I ran lspci -nn | grep -i network. The output is: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

  • Raid superblock missing on single parition. Recovery needed!

    - by user171639
    Ok so I have a 2 TB raid 1 setup that has three partitions: sdc1: linux sdc2: swap sdc3: LVM for data However the LVM will no longer mount. So I thought that I would take the first drive, mount it in linux (ive done this b4), and reset the spare drive to copy the data. Normally I can mount a single drive for data recovery using: sudo su apt-get install mdadm lvm2 mdadm --assemble --scan modprobe dm-mod vgscan vgchange -ay c mount -o ro /dev/c/c /mnt Unfortunately, vgscan doesnot recognize the data partition. It appears as though the superblock on the first drive's data partition was erased while syncing with the second. So now I cannot mount that partition and the second drive is stuck in spare mode. Any ideas? Or a way to force mount the data partition just to copy the data? knoppix@Microknoppix:~$ sudo su root@Microknoppix:/home/knoppix# apt-get install mdadm lvm2 Reading package lists...

    please tell I'm using Ubuntu 12.04 and if I have already created ext4 ./ (partition) and on the same volume I have ./home so if I create a separate partition ./home will the software that I install for example from Ubuntu Download Center will automatically go to ./home (partition) or still ./ (root) because I'm using PlayOnLinux and Wine and all its software only installs to ./home (file system disk) where emulated copy of Windows Xp installed also and it's a lack of space.

For this I tried to follow this guide: http://www.stanford.edu/~zxwang/android_opencv.html But when compiling the downloaded stuff with ndk-build I get this error: $ /cygdrive/u/flori/workspace/android-ndk-r5b/ndk-build Compile++ thumb : opencv <= cvjni.cpp Compile++ thumb : cxcore <= cxalloc.cpp Compile++ thumb : cxcore <= cxarithm.cpp Compile++ thumb : cxcore <= cxarray.cpp Compile++ thumb : cxcore <= cxcmp.cpp Compile++ thumb : cxcore <= cxconvert.cpp Compile++ thumb : cxcore <= cxcopy.cpp Compile++ thumb : cxcore <= cxdatastructs.cpp Compile++ thumb : cxcore <= cxdrawing.cpp Compile++ thumb : cxcore <= cxdxt.cpp Compile++ thumb : cxcore <= cxerror.cpp Compile++ thumb : cxcore <= cximage.cpp Compile++ thumb : cxcore <= cxjacobieigens.cpp Compile++ thumb : cxcore <= cxlogic.cpp Compile++ thumb : cxcore <= cxlut.cpp Compile++ thumb : cxcore <= cxmathfuncs.cpp Compile++ thumb : cxcore <= cxmatmul.cpp Compile++ thumb : cxcore <= cxmatrix.cpp Compile++ thumb : cxcore <= cxmean.cpp Compile++ thumb : cxcore <= cxmeansdv.cpp Compile++ thumb : cxcore <= cxminmaxloc.cpp Compile++ thumb : cxcore <= cxnorm.cpp Compile++ thumb : cxcore <= cxouttext.cpp Compile++ thumb : cxcore <= cxpersistence.cpp Compile++ thumb : cxcore <= cxprecomp.cpp Compile++ thumb : cxcore <= cxrand.cpp Compile++ thumb : cxcore <= cxsumpixels.cpp Compile++ thumb : cxcore <= cxsvd.cpp Compile++ thumb : cxcore <= cxswitcher.cpp Compile++ thumb : cxcore <= cxtables.cpp Compile++ thumb : cxcore <= cxutils.cpp StaticLibrary : libstdc++.a StaticLibrary : libcxcore.a Compile++ thumb : cv <= cvaccum.cpp Compile++ thumb : cv <= cvadapthresh.cpp Compile++ thumb : cv <= cvapprox.cpp Compile++ thumb : cv <= cvcalccontrasthistogram.cpp Compile++ thumb : cv <= cvcalcimagehomography.cpp Compile++ thumb : cv <= cvcalibinit.cpp Compile++ thumb : cv <= cvcalibration.cpp Compile++ thumb : cv <= cvcamshift.cpp Compile++ thumb : cv <= cvcanny.cpp Compile++ thumb : cv <= cvcolor.cpp Compile++ thumb : cv <= cvcondens.cpp Compile++ thumb : cv <= cvcontours.cpp Compile++ thumb : cv <= cvcontourtree.cpp Compile++ thumb : cv <= cvconvhull.cpp Compile++ thumb : cv <= cvcorner.cpp Compile++ thumb : cv <= cvcornersubpix.cpp Compile++ thumb : cv <= cvderiv.cpp Compile++ thumb : cv <= cvdistransform.cpp Compile++ thumb : cv <= cvdominants.cpp Compile++ thumb : cv <= cvemd.cpp Compile++ thumb : cv <= cvfeatureselect.cpp Compile++ thumb : cv <= cvfilter.cpp Compile++ thumb : cv <= cvfloodfill.cpp Compile++ thumb : cv <= cvfundam.cpp Compile++ thumb : cv <= cvgeometry.cpp Compile++ thumb : cv <= cvhaar.cpp Compile++ thumb : cv <= cvhistogram.cpp Compile++ thumb : cv <= cvhough.cpp Compile++ thumb : cv <= cvimgwarp.cpp Compile++ thumb : cv <= cvinpaint.cpp Compile++ thumb : cv <= cvkalman.cpp Compile++ thumb : cv <= cvlinefit.cpp Compile++ thumb : cv <= cvlkpyramid.cpp Compile++ thumb : cv <= cvmatchcontours.cpp Compile++ thumb : cv <= cvmoments.cpp Compile++ thumb : cv <= cvmorph.cpp Compile++ thumb : cv <= cvmotempl.cpp Compile++ thumb : cv <= cvoptflowbm.cpp Compile++ thumb : cv <= cvoptflowhs.cpp Compile++ thumb : cv <= cvoptflowlk.cpp Compile++ thumb : cv <= cvpgh.cpp Compile++ thumb : cv <= cvposit.cpp Compile++ thumb : cv <= cvprecomp.cpp Compile++ thumb : cv <= cvpyramids.cpp Compile++ thumb : cv <= cvpyrsegmentation.cpp Compile++ thumb : cv <= cvrotcalipers.cpp Compile++ thumb : cv <= cvsamplers.cpp Compile++ thumb : cv <= cvsegmentation.cpp Compile++ thumb : cv <= cvshapedescr.cpp Compile++ thumb : cv <= cvsmooth.cpp Compile++ thumb : cv <= cvsnakes.cpp Compile++ thumb : cv <= cvstereobm.cpp Compile++ thumb : cv <= cvstereogc.cpp Compile++ thumb : cv <= cvsubdivision2d.cpp Compile++ thumb : cv <= cvsumpixels.cpp Compile++ thumb : cv <= cvsurf.cpp Compile++ thumb : cv <= cvswitcher.cpp Compile++ thumb : cv <= cvtables.cpp Compile++ thumb : cv <= cvtemplmatch.cpp Compile++ thumb : cv <= cvthresh.cpp Compile++ thumb : cv <= cvundistort.cpp Compile++ thumb : cv <= cvutils.cpp StaticLibrary : libcv.a SharedLibrary : libopencv.so U:/flori/workspace/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebui lt/windows/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-andr oideabi/bin/ld.exe: cannot find -lcxcore collect2: ld returned 1 exit status make: *** [/cygdrive/u/flori/workspace/android/testOpenCV/obj/local/armeabi/libo pencv.so] Error 1 I am trying to compile it on a Windows system and with the newest NDK version... Does anybody have an idea what this linking error means and what I can to to have it work again? Would be great if anybody could help After getting the problem to work I found that there is another way of compiling OpenCV for Android, using the current version of OpenCV (instead of the 1.1 one from above) and the modified Android NDK from crystax, which supports STL and exceptions and therefore supports the newest OpenCV Version. All information on that can be found here: http://opencv.willowgarage.com/wiki/Android There it says to download the current svn trunk and the crystax-r4 android-ndk, as well as swig, which I did. I entered the folder, created the build directory, ran cmake and then built the static libs, which seemed to work. At least it successfully ran the make-command without errors. I now wanted to build the shared libraries so I entered the android-jni folder and ran 'make' again, but got this error: % make -j4 OPENCV_CONFIG = ../build/android-opencv.mk make clean-swig &&\ mkdir -p jni/gen &&\ mkdir -p src/com/opencv/jni &&\ swig -java -c++ -package "com.opencv.jni" \ -outdir src/com/opencv/jni \ -o jni/gen/android_cv_wrap.cpp jni/android-cv.i OPENCV_CONFIG = ../build/android-opencv.mk make[1]: Entering directory `/home/florian/android-opencv-willowgarage/android/android-jni' make[1]: warning: jobserver unavailable: using -j1.

  • Linq-to-XML query to select specific sub-element based on additional criteria

    - by BrianLy
    My current LINQ query and example XML are below. What I'd like to do is select the primary email address from the email-addresses element into the User.Email property. The type element under the email-address element is set to primary when this is true. There may be more than one element under the email-addresses but only one will be marked primary. What is the simplest approach to take here? Current Linq Query (User.Email is currently empty): var users = from response in xdoc.Descendants("response") where response.Element("id") != null select new User { Id = (string)response.Element("id"), Name = (string)response.Element("full-name"), Email = (string)response.Element("email-addresses"), JobTitle = (string)response.Element("job-title"), NetworkId = (string)response.Element("network-id"), Type = (string)response.Element("type") }; Example XML: <?xml version="1.0" encoding="UTF-8"?> <response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Account Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Alice</full-name> <network-id>79629</network-id> <stats> <followers>2</followers> <updates>4</updates> <following>3</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>alice</name> <web-url>https://www.yammer.com/domain.com/users/alice</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089943</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089943</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Office Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Bill</full-name> <network-id>79629</network-id> <stats> <followers>3</followers> <updates>1</updates> <following>1</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>bill</name> <web-url>https://www.yammer.com/domain.com/users/bill</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089920</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089920</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> </response>
