  • wpa_supplicant on lucid

    - by Thiago
    Hi, I'm trying to get my wifi working through the command line, but I'm not having success. I generated the wpa_supplicant.conf with wpa_passphrase and I'm running wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf. I only receive as a clue "Disconnect event - remove keys" and I get associated. What can I do?

  • How to chmod in Nautilus via keyboard?

    - by Joe Casadonte
    I like to use the mouse as little as possible, but I find Nautilus useful enough to use it when browsing for files. If I want to rename a file while in Nautilus I can hit the F2 key; is there a way I can chmod, too? I really hate going to properties and then permissions and then hitting the combo boxes one by one.... Thanks!

  • Installing raid 5 on a pre-installed ubuntu server. 12.04

    - by Chris
    I have a ubuntu server with samba already set up and installed with a 1tb hdd. I am wanting to now install 3 more 1tb drives and create a raid array using raid 5. I have found a lot of documentation about installing raid when installing and setting up ubuntu server for the first time. However, I am struggling to find anything on installing a raid 5 array on a system already installed an configured. Can this be done, or does a clean install need to be done again?

  • Jenkins swarm-plugin jar file, won't run in background

    - by JeanMertz
    We're working on an automation script for our Jenkins slaves on a local Unix server. To connect the slaves to the Jenkins master, we use the swarm plugin. Setting up the master was easy, and connecting clients is also easy with a single command. However, I am trying to get the slave command (a java application) to run in the background without stalling the current process, this doesn't seem to work. I've created an init.d file and added it to update-rc.d but that doesn't work. #!/bin/bash /usr/bin/java -jar /root/swarm-client-1.7-jar-with-dependencies.jar -executors 4 I've also tried to run it with an ampersand & to start the process in the background, but that doesn't work either because - from looking at the source - the jar file actually boots another process that is then started in the foreground. Any ideas on how to make this jar file start without stopping the bootstrap script?

  • Can Ubuntu create a semi-transparent subtitle player for accessibility?

    - by Tyler
    I've asked this in Reddit.com/r/Ubuntu in here. I've tried to get the Subtitle Player linked here to work and it have failed on Wine. So I'm curious if Ubuntu community would be willing to try and build a simple transparent subtitle player for better accessibility on Flash Player, Netflix, or even in movie theaters? Currently, I'm watching movies/videos with an Android Tablet that runs on a blank black video for 3 hours with a subtitle overlay on it so I can enjoy movie and so forth, but it requires a bit of effort and it definitely isn't for everyone. (People will have to look at the subtitle playing tablet and the movie back and forth at 60 degrees angle, while a transparent subtitle player would reduce it to 5 degrees angle to watch the movie.) Please and thank you.

  • I can't externally access my home server's wordpress website

    - by piratepartypumpkin
    Basically, I can access everything just fine using 127.0.0.1, but if I use my external IP (123.123.123.123), I get page not found. My router is port forwarding HTTP port 80 to port 8080 on my servers internal IP address. In other words: (Application: HTTP | Start: 80 | End: 8080 | Protocol: Both | IP Address 192.168.0.101 | Enable [YES]) I know it's forwarding properly, because when I stop port forwarding, I can access my router page by using my external IP. My virtual hosts file is: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /opt/lampstack-5.3.16-0/apps/wordpress ServerName example.com ServerAlias www.example.com </VirtualHost> and my httpd.conf file is: Listen 80 Servername localhost:80 DocumentRoot "/opt/lampstack-5.3.16-0/apache2/htdocs <Directory /> Options FollowSymLinks AllowOverride None Order deny, allow deny from all </Directory> <Directory "/opt/lampstack-5.3.16-0/apache2/htdocs"> Options FollowSymLinks AllowOverride None Order allow, deny allow from all </Directory>

  • Add multiple @groups to valid users

    - by skids89
    In smb.conf I have the line valid users = @Staff @Directors Is this a valid syntax to add two groups to the valid users line? It does not seem to work right on our xp pro clients. If not which of the following is the proper way (if any) to make two groups valid users of this network drive? Which is proper for windows clients? valid users = +Staff +Directors Or do I need to use the & valid users = &Staff &Directors Or some combo of the two? valid users = &+Staff &+Directors valid users = +&Staff +&Directors

  • Fried graphics card, how to proceed ?

    - by user19496
    Motherboard: Biostar TPower I45 I fried my graphics card (white smoke), by removing the cable marked PCI-E from the card, and then booting. Removed the graphics card, and now the machine is booting, and I can ping it. However I have no possibility to see what is actually happening, because I can't attach a monitor. Can I workaround the lack of monitor in some way, just to see if the motherboard is fine, attach a cable and telnet in or any other way ? Or, do I have to buy and install a new graphics card to be sure ?

  • multiple ip for a server not reachable

    - by andrewk
    FYI: I've read everything on Serverfault related to this question and have faced a different issue. Simply put, I've got one server (apache2) with couple of sites on it. It currently has 1 ip. I'm trying to assign/add another ip to that server, so I can give each site a different ip for ssl purposes. I am not lucking out. The new ip simply is unreachable, I've pinged it. This is what I've got below, what am I doing wrong. auto lo iface lo inet loopback auto eth0 eth0:0 eth0:1 iface eth0 inet static address 70.116.5.244 netmask 255.255.255.0 gateway 70.116.5.1 #THE NEW IP iface eth0:0 inet static address 26.175.217.102 netmask 255.255.255.0 #PRIVATE IP iface eth0:1 inet static address 192.168.158.88 netmask 255.255.128.0 NOTE: THESE IP'S ARE TWEAKED BUT RELATIVE I've read many questions here 90% similar to this but most actually have the IP respond, not this case.

  • Munin Aggregated Graphs Configuration Error

    - by Sparsh Gupta
    I tried making some Munin Aggregated graphs but somehow I am unable to make the configuration work. I think I have followed the instructions but since its not working, I would love some assistance or guidance as to what I am doing wrong. I want to Aggregate (sum) the total number of requests / second all my nginx servers are doing combined together. The configuration looks like [TRAFFIC.AGGREGATED] update no requests.graph_title nGinx requests requests.graph_vlabel nGinx requests per second requests.draw LINE2 requests.graph_args --base 1000 requests.graph_category nginx requests.label req/sec requests.type DERIVE requests.min 0 requests.graph_order output requests.output.sum \ lb1.visualwebsiteoptimizer.com:nginx_request_lb1.visualwebsiteoptimizer.com_request.request \ lb3.visualwebsiteoptimizer.com:nginx_request_lb2.visualwebsiteoptimizer.com_request.request \ lb3.visualwebsiteoptimizer.com:nginx_request_lb3.visualwebsiteoptimizer.com_request.request The munin graph I want to aggregate is http://exchange.munin-monitoring.org/plugins/nginx_request/details Thanks Sparsh Gupta

  • How to add nvidia drivers after previous failure with linux mint?

    - by LessThanMe
    Before today, I had perfectly good drivers from nvidia for my linux mint (15) box. I decided to update it because my performance in TF2 is less than stellar, and then things went south. I used synaptic to install nvidia-331 and then rebooted, but when I selected Mint in GRUB I waited...and waited...and waited. Nothing happened, but the display stayed on (a completely black video was being output). So I went into recovery mode from GRUB, went to root access, and apt-get remove --purge nvidia*'d my way out of that mess, and installed nvidia-common. Now my performance in graphic intensive stuff (read: games, blender) sucks, so I've been through the same thing a few times trying to re-install nvidia-current. I just want to get it back how it was. Thanks for any help! Nvidia GTX 560

  • Using GlusterFS for simple replication

    - by k7k0
    Hi, newbie question. I need to build this: /shared folder ~500GB of files, ~1MB each one. Two boxes (server1 and server2) connected by a 1Gbs LAN Every box needs to get r/w access to the files, so their are both clients I want that the files replicated on both boxes, every time a file is written in one server the same file should be present in the other one. My questions regarding GlusterFS: It'll duplicate the files on the same box?. For example the files are on /shared and the mount in /mnt/shared. It'll take 1GB space on every server? Instead, should I use the filesystem directly, locally writing on /shared? Does the replication work in this way without mountin a client? Also, if anyone know any other way to acomplish this setup I'll be very grateful. Thanks in advance.

  • How can find the USB wireless adapter into the dmesg log file?

    - by AndreaNobili
    I am pretty new in Linux (RaspBian for RaspBerry Pi but I think that there are not difference) and I have to install an USB wireless network adapter (the product is the TP-Link TL-WN725N, this one: http://www.tp-link.it/products/details/?model=TL-WN725N ) Now, I think that this is not automatically recognized by my system because if I execute ifconfig command I obtain the following output: pi@raspberrypi ~ $ ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:2a:9f:b0 inet addr:192.168.1.8 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:475 errors:0 dropped:0 overruns:0 frame:0 TX packets:424 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:34195 (33.3 KiB) TX bytes:89578 (87.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING 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) So now it see only my ethernet network interface and not the wireless. So I was thinkig to try to see into the dmesg, but I don't know what have I to see and how to select it into the dmesg output. For example by the following command I can see the line of the dmesg log file relate to my ethernet port: pi@raspberrypi ~ $ cat /var/log/dmesg |grep -i eth [ 3.177620] smsc95xx 1-1.1:1.0 eth0: register 'smsc95xx' at usb-bcm2708_usb-1.1, smsc95xx USB 2.0 Ethernet, b8:27:eb:2a:9f:b0 [ 18.030389] smsc95xx 1-1.1:1.0 eth0: hardware isn't capable of remote wakeup [ 19.642167] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 But what can I try to search for the USB wireless adapter? Tnx

  • Why doesn't my symbolic link work?

    - by orokusaki
    I'm trying to better understand symbolic links... and not having very much luck. This is my actual shell output with username/host changed: username@host:~$ mkdir actual username@host:~$ mkdir proper username@host:~$ touch actual/file-1.txt username@host:~$ echo "file 1" > actual/file-1.txt username@host:~$ touch actual/file-2.txt username@host:~$ echo "file 2" > actual/file-2.txt username@host:~$ ln -s actual/file-1.txt actual/file-2.txt proper username@host:~$ # Now, try to use the files through their links username@host:~$ cat proper/file-1.txt cat: proper/file-1.txt: No such file or directory username@host:~$ cat proper/file-2.txt cat: proper/file-2.txt: No such file or directory username@host:~$ # Check that actual files do in fact exist username@host:~$ cat actual/file-1.txt file 1 username@host:~$ cat actual/file-2.txt file 2 username@host:~$ # Remove the links and go home :( username@host:~$ rm proper/file-1.txt username@host:~$ rm proper/file-2.txt I thought that a symbolic link was supposed to operate transparently, in the sense that you could operate on the file that it points to as if you were accessing the file directly (except of course in the case of rm where of course the link is simply removed).
