• How can I change the default keyboard layout in Ubuntu 10.10?

  - by startoftext

  Ubuntu keeps detecting my keyboard layout as Romanian. It almost always does this on a reboot and some times on waking from sleep. Some times it just randomly changes back to Romanian while the computer is on. I always set it back to "USA" in the keyboard preferences and delete the Romanian layout. What files configure this in Ubuntu? I looked in xorg.conf and did not find any keyboard settings. How can I set this to USA permanently? I have a laptop with a typical US layout built in keyboard and I also have an apple keyboard that is also US layout connected via USB. I have run other distributions on this same setup before and never had this happen.

• Mouse/Touchpad not working in Mac OS X Lion Pre-Boot Authentication (PBA) with File Vault 2

  - by Chris

  I set up File Vault 2 in Mac OS X Lion with Pre-Boot Authentication (PBA). In PBA-login my USB-keyboard is working, while using a wrong keyboard layout. I can neither use my magic touchpad nor an USB-mouse in PBA. Thus I can't change the keyboard layout located in the upper right corner. I tried unplugging all USB-devices except keyboard and mouse. Nothing seems to help and the mouse cursor isn't moving. How can I get magic trackpad or USB-mouse to work in PBA login screen or manually set the used keyboard layout in PBA? Update: Still no (USB-)mouse or bluetooth trackpad support in File Vault 2 Login Screen. Today I talked to Apple Support for over one hour with no result. Every idea is appreciated.

• ubuntu boots into gnu grub 1.99

  - by greenish

  I've tried set root=(hd0,2) chainloader +1 boot set root=(hd0,2) linux /boot/vmlinuz... and the loopback (loop0) /ubuntu/disks/root.disk command etc. When I try the boot command it tells me there's no kernel and when I boot Win7 (it's a dual boot) the root.disk says 0kb. nothing boots from the live usb I've made and I've tried to use programs to mount the partitions to no effect - they only show me what's on my windows file drives. I've got some really important docs on the linux harddrive I need to get to. any ideas?

• Firefox bookmark with wildcard and keyword

  - by ThankYouToPositiveContributors

  In Firefox, how do I set up URL shortcuts that include a wildcard, %s? I have definitely set this up before on another computer. For example, if I wanted to view a Jira ticket, I would enter jira XXX-1234 into the address bar and it would take me to http://jira.sutureself.com:1234/browse/XXX-1234. I remember the entry added to Firefox would be http://jira.sutureself.com:1234/browse/%s, but I can't remember where I add that. EDIT I might add, I have done this without any additional addons.

• Samba Permissions

  - by Nelson

  I have Samba set up on a Fedora 15 Machine. All looks well except that there's something nagging and I don't know what exactly is causing it. I have a public share on the server which is accessible by everyone and its permissions is set to 777. When one person opens a document under that share and closes it after working, the other person who opens it can't edit or save it because it opens in read only and shows that it's still open on another computer. What might be causing this and how can I resolve this?

• How can I use sudo when I logged in with a SSH key in PuTTY?

  - by Alex

  I know the title probably doesn't even make sense, but anyway. I downloaded PuTTY and set it up, and followed this tutorial to set up SSH keys so I don't have to input a user or password when logging in with SSH. I noticed that when I made a new user I used the --disabled-password parameter, since I wouldn't be needing it... but now when I give the user sudo powers I can't proceed as it asks me for the user's password, and I don't have one. What do I do?

• Remote HTTP to FTP

  - by jamd12

  I am on a very slow download with the internet that I have and unfortunately I only have access to expensive and slow wireless or satelite. I have set up an FTP with a computer supplier locally who has a nice 2 Mbps speed and am trying to set up a way of adding links remotely (Hotfile, rapidshare, Fileserve, etc.) so that they can be downloaded onto the FTP and then transfered a few times a week manually onto a portable HDD. On my home PC I use Internet download manager for all my downloads. Is there a simple way that I can add links remotely to Internet Download Manager on the FTP or perhaps another solution? The OS on the FTP is Linux - I use Windows XP SP3 and Windows 7. I have not used FTP very much before so any suggestions on how best to do this would be much appreciated.

• how to restore windows 7 to a know working state every time it boots

  - by Artanis

  A couple of days ago my mother asked me to set up a computer at his house, she wants to use it to basic web browsing, video chat and nothing more. The problem is, neither my mother nor my sister know anything about using or maintaining a computer. What I want is to have a working base install of windows 7 and just discard everything installed, downloaded, ... when it reboots. That way I can set up a partition just for saving files and whatever they do the computer will always return to a working state at start up. can that be done? PS: Sadly linux is not an option since my sister wants to be able to play some games with my steam account and not all of them run with wine.

• Asking for brief explanation of reverse proxying and recommended software

  - by 80skeys

  I need to set up a reverse proxy where the backend web server is serving https pages only. I've never set up a reverse proxy and would like a brief overview of how it works. One of my questions is whether the proxy needs to run https also, or does simple http suffice? Second question would be whether to use Apache, varnish, nginx, or squid. This is for an internal site for a small company, so not a lot of traffic expected. Maybe a few dozen users each day.

• /dev/shm (shared memory) on linux

  - by Kirzilla

  Hello, Let's imagine that we have 8Gb of RAM on server. I'm mounting /dev/shm with 4Gb on board. mount -o remount,size=4G /dev/shm Will this memory be strictly reserved for shared memory or if /dev/shm is empty this memory could be used by regular applications (web server, php etc.)? PS:Sorry for my English. I'm asking it because I've just checked df -h and found tmpfs 6.0G 0 6.0G 0% /dev/shm on 8Gb RAM sever. I don't know who made this setup, but it seems to me awful. Thank you!

• Reverse Proxy Server SSL?

  - by valveLondon

  Context We currently have an Apache web server in the DMZ set up as a reverse proxy and load balancer for two machines running Windows Server 2008 (IIS) inside. The Apache server has a genuine SSL certificate and serves up both http and https, however, the balancer members in the load balancing section are set to: BalancerMember {https://server1} and {https://server2}. The IIS web servers have self-signed certificates in order to respond to the https requests. My question: Do we need to forward any requests from Apache (in the DMZ) to the inside using SSL? e.g can the reverse proxy forward the requests using HTTP? and if so, why would I choose to forward them with SSL? (how secure is the http line between the dmz and the inside); In other words, can I totally disable SSL on my inside web servers?

• PHP errors not being displayed

  - by Mike

  I'm using PHP with Apache on Ubuntu 12.10. Errors are not being displayed to the browser for some reason and I can't figure it out. I have the following in my php.ini file: error_reporting = E_ALL & ~E_DEPRECATED display_errors = On display_startup_errors = On log_errors = On I am also positive that I have edited the correct ini file by verifying it with php_ini_loaded_file(). I can also verify that the values are correctly set by doing the following in my script: echo ini_get("display_errors"); // Outputs 1 echo ini_get("display_startup_errors"); // Outputs 1 echo ini_get("log_errors"); // Outputs 1 echo ini_get("error_reporting"); // Outputs -1 I have tried what seems like every possible combination of these settings (and restarting Apache after each change) and it is just not outputting errors. I am also not using ini_set anywhere in the script. It is being set only from the ini file. Any ideas why errors aren't being displayed?

• Authenticated proxy in Windows command prompt

  - by tlvince

  My Internet access is delivered through an authenticated proxy. This is setup correctly in the "Internet Options" control panel applet and all browsing/GUI apps work fine. For cmd, proxy settings are typically set by exporting http_proxy. The applications I'm trying to use are git and Putty's pscp.exe. I've tried the following syntax to no avail: set http_proxy=http://username:[email protected]:port/ I've also experimented with Netsh.exe and ProxyCfg.exe with no luck. How does one configure an authenticated proxy in the Windows command prompt?

• Is there a software in windows that enables you to boot from a specific partition?

  - by Tono Nam

  I use acronis true image to mount images to my primary partition and it works great. lets say I have 3 partitions on my hard disk and all of them each is 600 GB. In the 3rd partition I keep files (documents, pictures etc), on the first partition is my primary partition where the operating system runs (windows 7). And in the 2nd partition is empty. I have an image of my primary partition and I save that image in my 3rd partition (50 GB is the size of the image so it fits in the partition number 3) and in an external hard drive. I know it is possible to install a new operating system in partition 2 such as windows xp but the only problem is that once I install that how could I tell the computer to boot from partition 1? is there a way to switch back and forth just like it's possible in the mac?

• Excel - Reuse a trend line to apply to other data

  - by milko

  I've obtained a trend line from a particular set of data. What I'd like to do now is to reuse this trend line to predict values from a given pair (x,y) of coordinates. To put it another way, I have one pair (x,y) that I know is correct for sure. I don't know any other point. Let's assume the behavior of this new set is similar to the one I've got the trend line from. Is there any way Excel could compute other points following this trend line?

• Raid1+0: create stripe over two /dev/mdx on partition or not?

  - by Chris

  Given that I haven't found a way to define how a Raid10 is created with mdadm, i went the Raid1+0 solution. How to display/define Mirror/Stripping pairs with mdadm mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdf1 mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdg1 /dev/sdh1 mdadm --create /dev/md10 --level=0 --raid-devices=2 /dev/md0 /dev/md1 My question is about the stripe. For the mirror I create a primary partition over the full HD and set partition type to FD. So, should I do the same for the Stripe? Create partition on /dev/md0 and /dev/md1 (primary over full 'HDD', set partition type correctly) and then do the stripe on the partition? Is there a correct way here or are there any advantages/disadvantages to a solution? Thank you

• iptables block everything except http

  - by arminb

  I'm trying to configure my iptables to block any network traffic except HTTP: iptables -P INPUT DROP #set policy of INPUT to DROP iptables -P OUTPUT DROP #set policy of OUTPUT to DROP iptables -A INPUT -p tcp --sport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A OUTPUT -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT The iptables output (iptables -L -v) gives me: Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 4 745 ACCEPT tcp -- any any anywhere anywhere tcp spt:http state RELATED,ESTABLISHED Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 2 330 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http state NEW,ESTABLISHED When I try to wget 127.0.0.1 (yes i do have a web server and it works fine) i get: --2012-11-14 16:29:01-- http://127.0.0.1/ Connecting to 127.0.0.1:80... The request never finishes. What am I doing wrong? I'm setting iptables to DROP everything by default and add a rule to ACCEPT HTTP.

• Grepping through the results of apachectl -S

  - by CamelBlues

  I have a server with about 300 virtual hosts. When I want to make sure a specific httpd.conf file is loaded into the Virual Host config and the syntax is correct, I run apachectl -S. The problem is, though, I get a ton of output. I've tried apacectl -S | grep 'foo' and apachectl -S > foo.txt to try and make this data a little bit more manageable, but the output of the command is not conducive to grepping or shoving into a text file. When I try apachectl -S | grep 'foo', it simply returns the entire output of apachectl -S. When I try apachectl -S > foo.txt, foo.txt is an empty file. This may have something to do with how the server is configured, because I am able to successfully grep on my local machine. Any suggestions?

• Is it possible to boot from internet?

  - by Calmarius

  Let's assume the following situation: you have a computer with empty hard disk, and you don't have a CD, floppy, pen drive nearby to boot the computer from. But you have connection to the Internet. Modern computers support network booting using PXE, but I haven't found anything regarding booting via the internet. So, is it possible to use PXE to load an image from the internet and boot it? By having a running system (even a minimal Linux) in RAM, it should be possible to install it on the hard disk, and build up a working system from here.

• Setting differing ACLs on directories and files

  - by durandal

  Quick ACL question: I want to set up default permissions for a file share so that everyone can rwx all of the directories and so that all newly created files are rw. Everyone who is accessing this share is in the same group, so this isn't a concern. I have looked at doing this via ACLs without changing all of the users' umasks and such. Here are my current invocations: setfacl -Rdm g:mygroup:rwx share_name setfacl -Rm g:mygroup:rwx share_name My problem is that while I want all of the newly created sub-directories to be rwx, I only want newly created files to be rw. Does anyone have a better method to achieve my desired end-result? Is there some way to set ACLs on directories separately from files, in a similar vein to "chmod +x" vs. "chmod +X"? Thanks

• How to change memory for DomU runtime

  - by saffron

  I have a xen server with xen-4.1.3, linux-image-3.2.0-3-amd64, debian squeeze and 16Gb of RAM. The domain-0 has 1Gb of ram, the rest of memory belongs to the hypervisor.

When I start a guest domain with 256Mb of ram and run xm mem-set domu 4Gb, I get ~3Gb only in domu and a guest domain free says: root@test:~# free total used free shared buffers cached Mem: 2830620 72868 2757752 0 2432 43504 -/+ buffers/cache: 26932 2803688 Swap: 1048572 0 1048572 And a guest domain dmesg says: [ 0.000000] Memory: 175912k/2883584k available (3527k kernel code, 448k absent, 2707224k reserved, 3210k data, 612k init) When I start a guest domain with 2Gb of ram I can run xm mem-set domu 7Gb and get ~7Gb of ram in a guest domain: root@test:~# free total used free shared buffers cached Mem: 6828228 74944 6753284 0 1328 12568 -/+ buffers/cache: 61048 6767180 Swap: 1048572 0 1048572 And a guest domain dmesg: [ 0.000000] Memory: 1674960k/16651264k available (3527k kernel code, 448k absent, 14975856k reserved, 3210k data, 612k init) How can I start a guest domain with a minimal amount of ram (256Mb) and increase it under 15Gb?

• Trouble with mod_rewrite and PHP Extensions - Help Making the Correct .htaccess File

  - by nicorellius

  I'm looking for a set of simple rules and redirects for my site. I've tried so many combinations that I'm starting to get confused. I'm not sure how to set this up. Generally, without mod-rewrite, I would use relative paths to link to files: <a href="link.php">Link</a> if it's in the same directory. Now I'd like to use this: <a href="link">Link</a> And so if you go to this page: localhost/mysite/link it will take you to the correct place, which would be: localhost/mysite/link.php But also, many directory levels deep I would like it to work as well: localhost/mysite/group/link2 would go to: localhost/mysite/group/link2.php and: localhost/mysite/group/section/link3 would go to: localhost/mysite/group/section/link3.php But then in all these cases, if someone were to type in this: localhost/mysite/group/section/link3.php in the URL bar, it would show this: localhost/mysite/group/section/link3 Thanks

• Extract duplicity difftar files manually

  - by isnogud

  I have a duplicity backup which i am not able to recover with duplicity. By calling duplicity file:///path/to/backups /path/to/dir, it returns "Local and Remote metadata are syncronized, no sync needed." but the /path/to/dir is empty. I decrypted all backup volumes and I'm able to view and extract the files from the different difftar files. My only problem is that there are files partitioned and saved in folders named after the files. Can anyone give me a simple script or at least a hint how to untar these difftar files so i get the actual files instead of the partitioned ones?

• Git multi-master, is it possible?

  - by Fran

  Hi, Is it possible to set a dual master GIT repositories? I would like to set up two different servers which I could push and commit to and changes on any of them would be propagated to the other. I've googled for it, but the most similar solution I've found is Gerrit2, but it does only one way replication (master - master). Does anybody know if this is even possible to do with git? If so, could you please tell me which tools to use? Thanks in advance.
