• ssh refuses to authenticate keys

  - by MixturaDementiae

  So I am setting up a connection between my machine [fedora 17] and a virtual machine running in Virtual Box in which is running CentOS 5. I have installed openssh from the repositories on CentOS, and I have configured everything as it follows: Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key SyslogFacility AUTHPRIV PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile /home/pigreco/.ssh/authorized_keys PasswordAuthentication no ChallengeResponseAuthentication yes GSSAPIAuthentication yes GSSAPICleanupCredentials yes UsePAM yes AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT AcceptEnv LC_IDENTIFICATION LC_ALL LANGUAGE AcceptEnv XMODIFIERS X11Forwarding yes Subsystem sftp /usr/libexec/openssh/sftp-server this is the configuration file sshd_config on the server i.e. on the CentOS. Moreover I have created a public/private key pair as usual on the .ssh/ folder in my home directory in my OS, i.e. Fedora, and then I've copied with scp the id_rsa.pub to the server and then I have appended its content to the file .ssh/authorized_keys on the server machine. The error that I get is the following: OpenSSH_5.9p1, OpenSSL 1.0.0j-fips 10 May 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 50: Applying options for * debug1: Connecting to 192.168.100.13 [192.168.100.13] port 22. debug1: Connection established. debug1: identity file /home/mayhem/.ssh/identity type -1 debug1: identity file /home/mayhem/.ssh/identity-cert type -1 debug1: identity file /home/mayhem/.ssh/id_rsa type 1 debug1: identity file /home/mayhem/.ssh/id_rsa-cert type -1 debug1: identity file /home/mayhem/.ssh/id_dsa type -1 debug1: identity file /home/mayhem/.ssh/id_dsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3 debug1: match: OpenSSH_5.3 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Server host key: RSA 16:e5:72:d1:37:94:1b:5e:3d:3a:e5:da:6f:df:0c:08 debug1: Host '192.168.100.13' is known and matches the RSA host key. debug1: Found key in /home/mayhem/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,keyboard-interactive debug1: Next authentication method: gssapi-keyex debug1: No valid Key exchange context debug1: Next authentication method: gssapi-with-mic debug1: Unspecified GSS failure.

• Is there a "deep" task manager available in Windows XP akin to Windows 7 and Vista?

  - by Ben McCormack

  Is there a good task manager or utility for Windows XP that gives deep visibility into the processes and threads running on the current system? I know that the task manager on my Windows 7 PC has a lot more information than does Windows XP. Any ideas?

• Limiting ssh user account only to access his home directory!

  - by EBAGHAKI

  By reading some tutorials online I used these commands: Make a local group: net localgroup CopsshUsers /ADD Deny access to this group at top level: cacls c:\ /c /e /t /d CopsshUsers Open access to the copSSH installation directory: cacls copssh-inst-dir /c /e /t /r CopsshUsers Add Copssh user to the group above: net localgroup CopsshUsers mysshuser /add simply put these commands will try to create a usergroup that has no permission on your computer and it only have access to the copSSH Installation directory. This is not true, since you cannot change the permission on your windows directory, the third command won't remove access to windows folder (it says access denied on his log). Somehow I achieved that by taking ownership of Windows folder and then i execute the third command so CopsshUsers has no permissions on windows folder from now on. Now i tried to SSH to the server and it simply can't login! this is kind of funny because with permission on windows directory you can login and without it you can't!! So if you CAN SSH to the server somehow you know that you have access to the windows directory! (Is this really true??) Simple task: Limiting ssh user account only to access his home directory on WINDOWS and nothing else! Guys please help!

• What is a long-term strategy to deal with CPU fan dust in my home office?

  - by PaulG

  There are numerous discussions of CPU overheating and how sometimes this can be corrected by removing the dust from the CPU fan. I have read many of these, but I can't find anyone expressing a long-term strategy to deal with this problem. There are some suggestions here, for example, about how often the inside of the computer should be dusted. But I find this generally unsatisfactory. As it stands, in my rather dusty house (heated by a wood stove, with no central air circulation), I need to vacuum out the CPU fan every 3 to 4 months. At high CPU load, this can make a difference between 65C and 100C. I'm tired of hauling out the vacuum every time I anticipate high CPU load. What steps can I take to deal with this systematically in the long-term? Moving my high CPU load computing to the cloud is not a realistic option. Neither is vacuuming my home office more than once a week! (Details: my computer is on the floor in a Cooler Master HAF922 case, and uses an Intel CPU fan on an i7 chip) EDIT: While this would definitely solve the problem (submerging motherboard in mineral oil), it is a bit of an expensive solution.

• Can I use a Windows Server 2003 Domain Controller but my home router for DNS?

  - by NetworkingWannabie

  Hi All Probably easiest to start with a description of my current setup, which works (oh, and this is a home setup not an office or anything): I have an ADSL modem with a static IP address (192.168.128.1), and its DHCP capability is disabled. I have a permanently powered up Windows Server 2003 machine with a fixed IP (192.168.128.2) which provides my domain controller, dhcp, and dns. The default gateway for everything is my ADSL modem everything is setup to use the WS2003 machine as the primary DNS with the ADSL modem as Secondary DNS just in case the server goes down (everything includes the server itself). Lastly, just in case it's relevant, I have my DHCP leases set to infinite (or whatever the right term is). Everything is pretty hunky dory. Except, that is, for the fact that my server is ALWAYS on, and it isn't always used, so I'm burning juice that I don't need to - my server burns around 120W which isn't immense but isn't irrelevant either, so I'd like to put it into a stand-by state when it isn't being used (the more standby the better) and then get the clients to wake it up. Am I correct in assuming that this won't work at the moment - A given client would need an IP address to wake the machine up, and it needs to machine to be awake to get an IP - catch 22? Assuming I'm correct, can I move to using my router (which is always on) for DHCP? What impact will this have on DC and DNS? Alternatively, does anyone have a better way for me to achieve this? Can I get the server to wake up when it sees clients look for a DHCP server, etc? Wow, that came out longer than expected! Thanks for your help.

• Apache 2: Mod_Rewrite Help - If/else for directory exists

  - by BHare

  This is my current and sloppy Apache 2 mod_rewrite. Keep in mine the part with site1 site2..etc has about 50 sites. RewriteEngine on RewriteCond %{HTTP_HOST} ^([^.]+)\.mainsite\.org$ RewriteCond /home/%1/ -d RewriteRule ^(.+) %{HTTP_HOST}$1 RewriteRule ^([^.]+)\.mainsite\.org/media/(.*) /home/$1/special/media/$2 RewriteRule ^([^.]+)\.mainsite\.org/(.*) /home/$1/www/$2 RewriteCond %{HTTP_HOST} ^mainsite\.org$ [NC] RewriteRule ^(.*)$ http://www.mainsite.org$1 [R=302] RewriteCond %{HTTP_HOST} (site1|site2|site3|site4)\.(com|net|biz|org|us)$ [NC] RewriteCond %{REQUEST_URI} !^/media/ RewriteRule ^/(.*)$ /home/%1/www/$1 RewriteCond %{HTTP_HOST} (site1|site2|site3|site4)\.(com|biz|net|org|us)$ [NC] RewriteRule ^/media/(.*)$ /home/%1/special/media/$1 RewriteCond %{REQUEST_URI} favicon.ico$ RewriteRule ^(.*)$ /misc/favicon.ico So if someone tries to go to theirusername.mainsite.org it will check if /home/theirusername/ exists, and if it does use their www (/home/theirusername/www/) as the file location for web files. If they try they try to access theirusername.mainsite.org/media/ it will make a special file location to look for the file(s) at /home/theirusername/special/media/ I would like it if the username did NOT have /home/username that it would automatically default to www.mainsite.org. I am having a hard time understanding how to do skips and such. so: If someone went to notrealusername.mainsite.org/forum/ it would auto direct to www.mainsite.org/forum/ Extra: I am using repetitive code for other site for example lets say foobar has a website foobar.com, it goes through the same process as mainsite.org so figured maybe having something like: RewriteCond %{HTTP_HOST} ^([^.]+).(mainsite.org|com|net|biz|org)$ where I could have one major rule for all existing domains who have a /home/

• Incompatible group permissions in Linux - Is it a bug?

  - by Sachin

  I am on Ubuntu 11.04. I am creating another user and placing an existing user in the group of other user, hoping to write in the home directory of other user. # uname -a Linux vini 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:18:14 UTC 2011 i686 athlon i386 GNU/Linux # whoami sachin # su root # useradd -m -U foo // create user foo # usermod -a -G foo sachin // add user `sachin' to group `foo' # chmod 770 /home/foo/ # exit # whoami sachin # cd /home/foo/ bash: cd: /home/foo/: Permission denied # groups sachin sachin : sachin foo This is totally weird. Though user sachin is in group foo, and group bits for /home/foo/ is set to rwx, sachin can't chdir to /home/foo/. I am not able to understand this. But, if at the exit step, I switch to sachin user from root, this is what happens: # uname -a Linux vini 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:18:14 UTC 2011 i686 athlon i386 GNU/Linux # whoami sachin # su root # useradd -m -U foo // create user foo # usermod -a -G foo sachin // add user `sachin' to group `foo' # chmod 770 /home/foo/ # su sachin # whoami sachin # cd /home/foo/ # ls examples.desktop Now, whatever is happening here is totally incomprehensible. Does su sachin inherits some permissions from the root user at this step? Any explanations would be much appreciated.

• Secure copy in Linux

  - by Michael

  Hi all, I wanna simpy exchange 3 directories to a collegue's home directory (I dont have write access to that one) from my home directory, probably using secure copy if possible. I am not good with Linux command line, so I am not sure how to do that and I would very much appreciate it if somebody could help me a bit out with this. I guess it should look something like that scp -r /home/user1/directoy1 /home/user2/directoy1 scp -r /home/user1/directoy2 /home/user2/directoy2 scp -r /home/user1/directoy3 /home/user2/directoy3 Do I need to specify the login name of my collegue so that the files can be copied when he enters his password? Thanks for your help, Michael

• _default_ VirtualHost overlap on port 443, the first has precedence

  I have two ruby on rails 3 applications running on same server, (ubuntu 10.04), both with SSL.

If you plan to use name-based virtual hosts, remember that they only work with your non-secure Web server. But not able to figure out how to run two ssl application on same server. Can any one help me?

• Why is ssh agent forwarding not working?

  - by J. Pablo Fernández

  In my own computer, running MacOSX, I have this in ~/.ssh/config Host * ForwardAgent yes Host b1 ForwardAgent yes b1 is a virtual machine running Ubuntu 12.04. I ssh to it like this: ssh pupeno@b1 and I get logged in without being asked for a password because I already copied my public key.

• Two-Hop SSH connection with two separate public keys

  - by yigit

  We have the following ssh hop setup: localhost -> hub -> server hubuser@hub accepts the public key for localuser@localhost. serveruser@server accepts the public key for hubuser@hub.

• What differences are there between "home" switches and "professional" switches?

  - by pjreddie

  Our radio station uses a PtP wireless system to stream our radio and TV signals from our studio up a hill to our transmitter. We have been having problems with warbly sound and drop outs that come from some point in this system. An engineer that occasionally visits the station thinks it could be the switches we use on each side of the PtP wireless system to connect the PtP devices to the encoders and decoders and wants us to get two of these switches: http://www.amazon.com/Netgear-JGS516-ProSafe-16-Port-Ethernet/dp/B0002CWPOK/ref=dp_return_1 The encoder/decoder setup only streams 8Mbps total so it seems like the switches we have should not be stressed out, unless they are causing sufficient latency to degrade the performance of the encoder/decoder. At each end of the connection we only have 4 connections, is there any reason we couldn't get a cheaper, "home" quality switch like this: http://www.amazon.com/D-Link-DGS-1005G-5-Port-Gigabit-Desktop/dp/tech-data/B003X7TRWE/ref=de_a_smtd Is there a significant difference that we would notice in terms of latency between these two switches? How much does the quality of the switch actually matter in this scenario? Any help is appreciated, feel free to ask questions if anything needs clarification. Thanks

  Whenever I try to ping another box on my home network, it pings the wrong ip address: C:\Users\Papa>ping macmini Pinging macmini.belkin [208.68.143.55] with 32 bytes of data: Reply from 208.68.143.55: bytes=32 time=50ms TTL=110 As you can see it always appends belkin to anything I try to ping. So I hit up ipconfig and belkin happens to be Connection-specific DNS Suffix: Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : belkin IPv4 Address. . . . . . . . . . . : 192.168.2.7 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.2.1 My setup is all DHCP, so I am not sure where belkin is coming from. I looked through all the networking stuff, as you can see below: Bottom line: how do I fix this?

• How do you disable the magnifier in Windows Vista?

  - by PhantomDrummer

  Every so often while I'm working, if I accidentally jolt the mouse, the magnifier starts. I'm fairly sure the cause is that some comination of mouse keys is supposed to start the magnifier, and I occasionally hit the right keys accidentally. However, I've never been able to reproduce the behaviour deliberately so I don't know which combination. This is very annoying since switching the magnifier off is non-trivial (control panel, or run dialog, which are hard to use when the magnifier keeps - ummm - windowing and magnifying the bit of screen you're about to click on :-) ). So I'm wondering if there's any way to disable the magnifier completely, so that it doesn't start when you do whatever it is you'd normally do to the mouse to start it? Anyone know?

• extra managed+unmanaged switches @ home/office -- best (mis)usage scenario? what would you do?

  - by locuse

  up front -- definitely NOT a mission-critical kind of question. after a 'spring cleaning' of my local office, i've ended up with two 'spare' GigE switches at my home/office -- one managed, capable of VLANs, QoS, etc, and the other unmanaged. i've got more ports than i need. in fact EACH switch has more total ports than i need. but, since i can't have these just sitting around not doing SOMETHING ... ;-) i'm interested in ideas for best combined use of these switches. my local topology is simple: [ net ] -- [ adsl2 modem ] -- [linux firewall/router/DNS ] _______________| | [ some arrangement of the 2 GigE switches ] | ( ... stuff on the lan ... ) [WAP1] [voip ATA] [printer] [desktop1] [mail server] [Xen server [desktop2] ( mostly dev, [desktop3] + file server [desktop4] + media server)] the MailServer is a production mail server the XenServer serves some low vol to the 'net; the MediaServer guest serves ONLY to the LAN is there, e.g., any performance value in segmenting off any of the LAN using the managed switch (VLAN? QoS tagging? something?), feeding the rest into the connected unmanaged switch? or should i simply use one of the switches & be done with it, and use the other for a coffee-cup stand?

• What needs updating when moving a bootable Windows 7 (or Vista) partition?

  - by SuperTempel

  When I move a bootable NTFS partition with Windows on it to a different block offset, what needs updating to make it bootable again? In particular, here's what I tried: I have a disk with several partitions, one of which is the NTFS partition with Windows on it, and the disk uses the plain old MBR block 0 for the partitions layout (no more than 4 partitions). Now I format and partition a new, larger, disk. There I make room for the NTFS partition and copy the contents from the old disk's NTFS Windows partition into. And I make the partition "active". However, when I try to boot from this disk, I get a "read error" message immediately and the booting stops, the exact text is: A disk read error occurred Press Ctrl+Alt+Del to restart I verified that both disks have the same boot sector code in block 0. It seems to me that something else might need updating. I guess that somewhere there's a absolute block reference that I need to update, probably pointing to the next level loader or to the NT kernel. Update: I found this article going quite into the depth of what I want to know. However, it says to modify boot.ini, but I have Windows 7 installed here, where such things appear to have changed: No boot.ini but a folder called System Volume Information with GUID and other data in it that sounds related to my problem. Going to keep digging... Update 2: Thanks to the terrible looking but very informative website by starman, I was able to figure out the first step: The NTFS boot sector has a field for "hidden" sectors. This feld has to contain the sector number of the boot sector. This solves the "read error" message. Now, however, I get a "BOOTMGR is missing" error instead. Looks like there's another place where a block number has to be adjusted, but I can't find anything in the code listing about this. I do find a lot of help sites suggesting Windows tools for fixing this "BOOTMGR is missing" problem, but none seem to know what goes on behind the scenes. Kind of like suggesting to re-install Windows when there's a little problem with it. At least, those fixes seem to work, mostly involving the Bcdedit and Bootrec tools. Now, who knows what they do, especially the latter, in regards to a moved partition? Update 3: After lots of trial-and-error attempts, I believe now that the solution lies in the BCD-Template registry file, residing usually inside \Windows\System32\config. If I get this updated using the "bcdboot" command, Windows starts up from it. I am now in the middle of figuring out what information this registry contains relevant to the above question. Any pointers to the contents of this registry are welcome. Update 4: Turns out that while the BCD-Template file gets rewritten and has different binary contents than its predecessor, the values inside do not change. So it must be something else that bcdboot.exe writes. I had previously already checked if it changes the first 32 boot blocks of the partition, but they appear to remain unchanged. Parititon map doesn't get changed, either. So what is it that bcdboot modifies besides the BCD registry? Any tips on how I can trace that? Are there low level tools that show me what files a program writes to? Update 5: The answer seems to be: c:\Boot\BCD is also changed, and that appears to be the key file for the boot manager's process. I'll investigate this later... Update 6: It seems to be an important detail that I had originally two partitions created when I installed Windows 7: A small partition of 204800 sectors which appears to be a bootstrap partition, followed by the actual, large, partition containing the Windows system (drive C:). When I tried to transfer this installation to a new, larger, disk, I had kept the same two partitions intact on the new drive, although they ended up at a different offset. This alone led to the "BOOTMGR is missing" message. Since then, I've used bcdboot.exe only on the Windows partition, which added the \Boot\BCD file on that partition. That file (and folder) did originally only exist on the smaller partition. Hence, this problem may be more complicated in my case as one partition (the boot strapper) referred to another partition (the one containing the OS), whereas other people may only have to deal with one partition containing both, and maybe there the solution is simpler. Update 7: Found one more detail: The \Boot\BCD file records the MBR's serial number. If that number doesn't match, the system won't boot. Next I'll test if there's also an absolute block reference stored in there.

• How to prevent Vista from entering Sleep mode when certain conditions exist?

  - by idyllhands

  Mainly, I would like to prevent my laptop from entering Sleep mode when I am playing music or streaming video. This is on my laptop, so another option that would work would be to prevent sleep mode whenever the laptop is plugged into my tv via HDMI (ie when HDMI port is in use). Or prevent sleep mode whenever there is audio playing.. I am soon upgrading to Windows 7, so solutions using 7 would be great also/instead. Thanks!

• How to set up django-admin.py on windos vista?

  - by shin

  I manage to install Django after some struggles by using setup.py install on Windows Vista Now I tried to use django-admin.py but it is not working. According to this document, http://docs.djangoproject.com/en/dev/ref/django-admin/ The django-admin.py script should be on your system path if you installed Django via its setup.py utility. If it’s not on your path, ... For Windows users, who do not have symlinking functionality available, you can copy django-admin.py to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location. I checked ComputerpropertiesEnvironment Variables, but path to django-admin.py is not in anywhere. So I added C:\Python25\Lib\site-packages\django\bin which is the folder of django-admin.py in User variables for shin Variable PATH, Value C:\Program Files\Google\google_appengine\;C:\Python25\Lib\site-packages\django\bin\ Am I supposed to add to System variables?? But it still does not work. Could anyone tell me how to add the Path in Environment Variables please? Thanks in advance.

• APC decreasing php performance??? (php 5.3, apache 2.2, windows vista 64bit)

  - by M.M.

  Hi, I have an Apache/2.2.15 (VC9) and PHP/5.3.2 (VC9 thread safe) running as an apache module on Vista 64bit machine. All running fine. Project that I'm benchmarking (with apache's ab utility) is basically standard Zend Framework project with no db connection involved. Average (median) apache response is about 0.15 seconds. After I've installed APC (3.1.4-dev VC9 thread safe) with standard settings suddenly the request response time raised to 1.3 seconds (!), which is unacceptable... All apc settings looked always good (through the apc.php script: enough shm memory, no cache full, fragmentation 0%). Only difference was to disable the stats lookup (apc.stat = 0). Then the response dropped to 0.09 seconds which was finally better than without the apc. IIRC, it's expected and obvious that the stat lookup creates some overhead, but shouldn't it still be far more performant compared to running wihout the apc extension at all? Or put it differently why is the apc.stat creating so much overhead? Apparently, something is not working as it should, I don't really know where to start looking. Thank you for your time/answers/direction in advance. Cheers, m.

• Commercial Drupal Modules & Themes

  - by Ravish

  A discussion at Drupal.org forums prompted me to give my input about commercial ecosystem around Open Source Content Management Systems. WordPress and Joomla have been growing rapidly since past few years. But, growth rate of Drupal seems to be almost flat. Despite being the most powerful CMS around, Drupal is still not being adopted by masses. Many people will argue that Drupal is not targeted towards masses, but developers. I agree, Drupal is more of a development platform than a consumer CMS. Drupal is ‘many things to many people’, and I can build almost any type of website with it. Drupal is being used for building blogs, corporate websites, Intranet portals, social networking and even a project management system. Looking at the wide array of Drupal implementations, it deserves to be the most widely adopted CMS. I believe there are few challenges that Drupal community needs to overcome. To understand these challenges, I surveyed some webmasters who use Joomla or WordPress but not Drupal. I asked them why they don’t want to use Drupal, following are the responses I got from them: Drupal is too complicated, takes time to learn. Drupal is great, but its admin panel is overwhelming. I couldn’t find any nice themes for Drupal. There is no WYSIWYG editor in Drupal. Most Drupal modules do not work out of the box. There aren’t enough modules like Ubercart which provides any out of the box functionality. I tried modules like CCK, Views and Panels. After wasting several hours struggling with them, I decided to give up on Drupal. I don’t use Drupal because of pushbutton and Garland theme. I had hard time trying to customize Garland and it messed up the whole layout. There are no premium modules and themes for Drupal. Joomla has tons of awesome themes and modules. I don’t want a million hacks like CCK, Views, Tokens, Pathauto, ImageCache and CTools just to run a simple website. Most of the complaints from users are related to the learning and development curve involved with Drupal, and the lack of ecosystem. While most of the problems will be gone in Drupal 7, ecosystem is something that needs to be built by the Drupal community. Drupal distributions are a great step forward. There are few awesome Drupal distributions available like Open Publish, Open Atrium and Drupal Commons. I predict, there will be a wave of many powerful Drupal distributions after Drupal 7 release. Many of them will be user-friendly and commercial supported. Following is my post at Drupal.org forums: Quote from: http://drupal.org/node/863776#comment-3313836 Brian Gardner (StudioPress) and Woo Themes launched premium WordPress themes in 2007, the developer community did not accept it at first. Moreover, they were not even GPL licensed. There was an outcry in WordPress community against them. Following that, most premium theme providers switched to GPL licensing. Despite controversies, users voted for premium theme and plugins by buying them. Inspired by their success, hundreds of other developers started to sell premium themes and plugins. It is now the acceptable and in fact most popular business model among WordPress community. Matt Mullenweg once told me, they would not support premium themes. If he supported, developers would no more give out free GPL themes & plugins. He pointed me towards Joomla, there were hardly any nice free themes & modules available. Now two years forward, premium products are not just accepted but embraced by the WordPress community – http://wordpress.org/extend/themes/commercial/ The quality and number of themes & modules has increased, even the free ones. This also helped to boost the adoption and ecosystem of WordPress. Today, state of Drupal is like WordPress was in 2007. There are hardly any out of the box solutions available for Drupal. Ubercart, Open Publish and Open Atrium are the only ones I can think of. Many of the popular Drupal modules are patches and hole-fillers. Thankfully, these hole-filler modules are going to be in Drupal 7 core. Drupal 7 and distributions will spawn a new array of solutions built upon Drupal. Soon, we will have more like Ubercarts and Open Atriums. If commercial solutions can help fuel this ecosystem and growth, Drupal community will accept them eventually. This debate will not stop your customers from buying your product. If your product is awesome, they will vote for you by buying your product.

• Automatic Standby Recreation for Data Guard

  - by pablo.boixeda(at)oracle.com

  Hi,Unfortunately sometimes a Standby Instance needs to be recreated. This can happen for many reasons such as lost archive logs, standby data files, failover, among others.This is why we wanted to have one script to recreate standby instances in an easy way.This script recreates the standby considering some prereqs:-Database Version should be at least 11gR1-Dummy instance started on the standby node (Seeking to improve this so it won't be needed)-Broker configuration hasn't been removed-In our case we have two TNSNAMES files, one for the Standby creation (using SID) and the other one for production using service names (including broker service name)-Some environment variables set up by the environment db script (like ORACLE_HOME, PATH...)-The directory tree should not have been modified in the stanby hostWe are currently using it on our 11gR2 Data Guard tests.Any improvements will be welcome!
