• Seeking past end of file causes Apache hang, and it never restarts.

  - by talkingnews

  I've actually solved my problem with a better script, but I'm still left wondering why Apache2 hung completely - this is an out-of-the-box ISPCONFIG 3.03 install, everything bang up to date, running perfectly. Until... The troublesome but innocent-looking script: $fp = fopen("/var/log/ispconfig/cron.log", "r"); fseek($fp, -5000, SEEK_END); $line_buffer = array(); while (!feof($fp)) { $line = fgets($fp, 1024); $line_buffer[] = $line; $line_buffer = array_slice($line_buffer, -10, 10); } foreach ($line_buffer as $line) { echo $line; } You get the idea, just a script I found on a forum somwehere. I did this for various logs, since it's a nice easy window on what's occurring (in a protect dir, of course!). One day, the logs having grown large an me having sorted all my cron, scripting and mail queue errors, I thought I was time to start afresh. updated, rebooted, archived and deleted the logs. When I ran my script a couple of hours later, it hung. And hung. 8 minutes I waited. Chrome timed the page out, of course, but the server never came back to life. htop showed /usr/sbin/apache2 -k restart using 100% CPU. Never came back until I did a service apache2 restart. Ran fine, as soon as I hit that logfile again...dead. So, I worked out it was the logfile script, and I worked out that seeking beyond the end of the file wasn't good, and I found a better script http://www.php.net/manual/en/function.fseek.php#90450 But what I'm left wondering is... why didn't something restart or kill the process? How was one hanging page able to bring down the whole server? It's running suphp. I say "out of the box", I've tweaked mysql and apache to fork and reserve sensible amounts of processes for the 512Mb RAM the VPS has, and it'll handle multiple refreshes of large pages, and hadn't hung before. Any ideas how I'd avoid this? Google isn't my friend in this instance beyond the reccs. above about number of processes vs RAM available.

• Running an rsync sweep before initializing lsyncd for synchronizing instances on EC2

  - by chrisallenlane

  My company uses several EC2 servers that will scale up and down according to the load we're receiving on our sites at any given moment. For the sake of our discussion here, we're running four instances: master.ourdomain.com - the file syncing "hub" of the webservers www1/www2/www3.ourdomain.com - three webservers which turn on or off as dictated by load I'm using lsyncd to keep all of the webservers in sync, and for the most part, it's working quite well. We're using a two-way syncing scheme, such that each webserver syncs against master, and master syncs against each webserver. Thus, the webservers are kept in sync, even though they aren't syncing against each other directly. I'm having one problem that I'm having a hard time solving,though. It occurs under these circumstances: When changes are made on master (perhaps after we've pushed new code), while some of the redundant webservers are sleeping And then a sleeping webserver wakes-up to absorb load Under that circumstance, I would like the following to happen: First, the newly-awoken webserver should sync its file structure - one way - against master, to bring its web application code up-to-date. Then, and only then, should it begin pushing changes in its file structure back to master. Unfortunately, currently, when a sleeping server is started, when lsyncd starts up, it pushes changes back to master before updating its own codebase, thus overwriting new code with old. Thus, before lsyncd starts, I'd like to be able to synchronize the webservers code against master's, perhaps by running a simple one-way rsync against the two machines. We're running lsyncd v.2, and I've tried to make this happen by using the "bash" configuration options documented in the lsyncd manual. My configuration file looks like this: settings = { logfile = "/home/user/log/lsyncd/log.txt", statusFile = "/home/user/log/lsyncd/status.txt", maxProcesses = 2, nodaemon = false, } bash = { onStartup = "rsync [email protected]:/home/user/www /home/user/www" } sync{ default.rsyncssh, source="/home/user/www/", host="[email protected]", targetdir="/home/user/www/", rsyncOpts="-ltus", excludeFrom="/home/user/conf/lsyncd/exclude" } (I've obviously redacted that file somewhat to protect the identities of the guilty.) Simply put, though, this just isn't working. How else might I approach this problem? I was looking at the --delete-after option in man rsync, but I don't think that does what I'm looking for. Are there any suggestions about how I should approach this problem? Thanks for lending your time and expertise. Chris

• Dell PowerEdge R720 - Corrupted RAID

  - by BT643

  Apologies in advance for the lengthy question. We have a Dell PowerEdge R720 server with: 2 x 136GB SAS drives in RAID 1 for the OS (Ubuntu Server 12.04) 6 x 3TB SATA drives in RAID 5 for data A few days ago we were getting errors when trying to access files on the large RAID 5 partition. We rebooted the server and got a message about the raid controller has found a foriegn config. We've had this before, and just needed to use Dell's RAID configuration utility to import foreign config on the RAID. Last time this worked, but this time, it started doing a disk check then we got this: FSCK has returned the following: "/dev/sdb1 inode 364738 has a bad extended attribute block 7 /dev/sdb1 unexpected inconsistency run fsck manually (i.e without -a or -p options) MOUNTALL fsck /ourdatapartition [1019] terminated with status 4 MOUNTALL filesystem has errors /ourdatapartition errors where found while checking the disk drive for /ourdatapartition Press F to fix errors, I to Ignore or M for Manual Recovery" We pressed F to try and fix the errors, but it eventually errored with: Inode 275841084, i_blocks is 167080, should be 0. Fix? yes Inode 275841141 has an invalid extend node (blk 2206761006, lblk 0) Clear? yes Inode 275841141, i_blocks is 227872, should be 0.

We replaced the drive with a spare, and tried "F" to repair it again, but we keep just getting the same error as above. In the RAID configuration utility, all drives show as "online" and "optimal". We do have this data on another replicated server, so we're not worried about "recovering" anything, we just want to get the system back online asap. The server has 64 or 32GB memory, can't remember off the top of my head, but either way, with a 14TB RAID, I think it may still not be enough. Thanks EDIT - I checked the memory usage while fsck was running as suggested and after 2 or 3 minutes, it looked like this, using up nearly all of our servers memory: When it failed after 5 minutes or so with the error in my post, the memory immediately freed up again:

• Upgrading php from php 5.3 to 5.4 .7

  - by Takingsides

  So, quickly so to speak I have noticed this topic around, I have searched and there are plenty of solutions. However these solutions do not work for me, not only that but I'm intending to learn more about the Debian based OS. Questions I would like to know how to upgrade php5.3 to php 5.4.7 compiling it from source, myself without using a third-party ppa. Is the way (explained below) the correct way of configuring php5.4? I'm new to compiling from source. Set-up I run Ubuntu Server 12.04 64bit. I've currently got: PHP 5.3 MySQL-Server Apache2 Memcached The Problem So I initially installed php5.3 using apt-get. I now wish to upgrade the php 5.4 due to the advantage of traits in OOP and the struct with Arrays and all the other recent patches and such. Possible Solutions I've seen this ondrej/ppa repository, which I refuse to use, given the fact that it may work, but it's an unknown/untrusted source. ALso, i'm not learning how to administer from source, using configure, make and install accordingly. I've seen a solution compiling from source, which is essentially how I was hoping to go about it with some guidance. Conclusion So I didn't just expect to be spoon-fed, and I went out and did some manual reading and atleast started the ball rolling myself; this how far i've got. The first thing I did was su into root (to save the typing sudo all the darn time). $ sudo su The next thing I did was download the latest version of php (5.4.7) and extracted it's contents ready to configure before installing it. $ mkdir php5-new && cd !$ $ wget -O php-5.4.7.tar.bz2 http://php.net/get/php-5.4.7.tar.bz2/from/uk3.php.net/mirror $ bzip2 -d php-5.4.7.tar.bz2 $ tar xvf php-5.4.7.tar.gz $ cd php-5.4.7 $ ./configure --help Finally I decided to have a bash, I looked through the list of options and decided I needed to list ALL of the things I wanted to include in the configuration. $ ./configure --with-mysql --with-apache2 --with-libxml --with-openssl --with-zlib --with-bz2 --with-curl --with-dom --with-gd --with-imap --with-imap-ssl --with-mcrypt --with-mysqli --with-pdo-mysql --with-libxml --enable-ftp --enable-mbstring --enable-soap Finally, the results... When the configuration process had finished, it threw an error: configure: error: xml2-config not found. Please check your libxml2 installation.

• How do I (robustly) remotely execute tasks on Windows workstations in a domain?

  - by Zac B

  I'm not even sure if "robustly" is a word. Anyway. Context: We have a few hundred Windows 7 workstations on a LAN. We use AD/GPO management pretty heavily, but there are a lot of periodic and/or manual maintenance tasks we need to do that can't be done via GPO/scheduled task. For example, say I want to execute program X (which runs silently, in the background, and doesn't bother the user) on workstation Y, or say I want to execute task A on a workstation group B either on a schedule or on demand. Kicking the users off of their computers to do this (i.e. using RDP) is a no-no, and doesn't work on groups anyway. Question: What's the best way to do this that is robust enough that, after setup, I could give it to beginner support people (read: people who are phobic of the command line, and get confused with GUI interfaces more complicated than Firefox)? I'm a competent programmer, and, if there is a robust set of tools or framework out there for this type of task, I'd consider hacking something together myself if it didn't take too long. If there's some combination of tools or techniques that others use to make remote-workstation-administration doable by beginners, I have yet to find it. For those who care about the "why": I'm midlevel IT, and was told to implement a remote management solution that allows arbitrary/scheduled remote execution, with confirmation that programs actually ran remotely, and the ability to view what they returned. "Why?" I asked, "Can't I just use PsExec and the task scheduler on a dispatcher machine?" "No," I was told, "'Joe' the second-week tech is going to be in charge of this one, and he needs something simple with a GUI." What I've tried: I've played with making a bunch of one-clickable "transfer files to remote computer and run them with PsExec" batch/VB scrips, but those tend to break down and don't easily support running on customizable groups. I've played a little bit with the Windows version of Puppet, but it doesn't support arbitrary-time remote execution (it's ability to group computers into a tree/node structure is really nice though). I've used an older version of Altiris, and, while it does a lot of what I want, it's interface is awful, it's slow, crashes a lot, and is probably too expensive for management. SwiftWater's DMS solution does some of what I want, but it's very underdeveloped, closed-source (not a deal breaker but not ideal), and I get the impression that support and reliability are lacking.

• Is there a switch that will connect directly to my modem and allow my router to serve only as a WiFi connection?

  - by Abner

  Details . . Devices . Internets -50Mbps Cable Internet Modem - Motorola Surfboard Extreme Router - Netgear WNDR3700v3 Switch - D-Link DGS-1008G Wired Ethernet Cable - Cat6_24Awg_ Device Configuration - Modem\Router\Switch . . Internet Usage . Wired Demand XBOX 360 1 Gaming PC 2 PC - HD video . WiFi Demand 3 android + 1 Laptop for browsing and group video chat simultaneously . . Specifics . I am experiencing problems with network speeds and reliability on both wired and wireless connections. On many occasions I experience WiFi Speeds that vary between the 15mbps to 0.50 mbs (or less) and ping ranging from 15ms to 500ms. These results are from when I notice problems with internet lag and run speedtest.net to get details of problems. I have a stretched out floor-plan and old building materials drastically affecting my cellphone signal strength as well). After Reading the "Known Issues" Section on the webpage below http://www.dd-wrt.com/wiki/index.php/Netgear_WNDR3700#Known_Issues I bought the switch and Cat6 cable to increase speed and relieve stress on router in an attempt to fix the symptoms. I thought I'd use the router in a Modem\Switch\Router configuration. I thought I'd only have to use the router for mobile WiFi connections like android or Laptops when necessary (hopefully eliminating the problem caused by the router when subjected to all those demanding Ethernet connections) When I started unboxing the switch, I noticed the manual of this DGS-1008G shows it being connected in the Modem\Router\Switch order and not in the Modem\Switch\Router configuration I was aiming for. I have not been able to find a solid plan to remedy my specific problem without buying another expensive router. I would like to get the speeds I am paying for without buying another router. (My WiFi Adapters would also need to be updated if new router is required, meaning more $$$). I can always sell the switch and get a better one that will bypass the router because my most demanding internet connections are Wired. . . Questions Can I accomplish a Modem\Switch\Router configuration with current switch? Is there a different way to get the wired speed I need while providing WiFi only when necessary? . .

• Puppet and launchd services?

  - by Joel Westberg

  We have a production environment configured with Puppet, and want to be able to set up a similar environment on our development machines: a mix of Red Hats, Ubuntus and OSX. As might be expected, OSX is the odd man out here, and sadly, I'm having a lot of trouble with getting this to work. My first attempt was using macports, using the following declaration: package { 'rabbitmq-server': ensure => installed, provider => macports, } but this, sadly, generates the following error: Error: /Stage[main]/Rabbitmq/Package[rabbitmq-server]: Could not evaluate: Execution of '/opt/local/bin/port -q installed rabbitmq-server' returned 1: usage: cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-s] [-d delim] [file ...] while executing "exec dscl -q . -read /Users/$env(SUDO_USER) NFSHomeDirectory | cut -d ' ' -f 2" (procedure "mportinit" line 95) invoked from within "mportinit ui_options global_options global_variations" Next up, I figured I'd give homebrew a try. There is no package provider available by default, but puppet-homebrew seemed promising. Here, I got much farther, and actually managed to get the install to work. package { 'rabbitmq': ensure => installed, provider => brew, } file { "plist": path => "/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist", source => "/usr/local/opt/rabbitmq/homebrew.mxcl.rabbitmq.plist", ensure => present, owner => root, group => wheel, mode => 0644, } service { "homebrew.mxcl.rabbitmq": enable => true, ensure => running, provider => "launchd", require => [ File["/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist"] ], } Here, I don't get any error.

• Trying to get DNS services running on Windows Server 2008 R2, what am I getting wrong ?

  - by LaserBeak

  Ok, So I am basically trying to get a home server pc up that will provide Domain name services, act as Mail server and web server. I have one static IP, well it's not officially static but hasn't changed in two years so I'll call it static. I have done the following: Configured router NAT/virtual port forward UDP/TCP port 53 to the internal IP of my server 192.168.1.16, in adapter settings specified the manual settings: 192.168.1.16 IP, gateway 192.168.1.1, Subnet: 255.255.255.0 and loopback DNS: 127.0.0.1 Using my public my public IP Checked using http://www.canyouseeme.org/ that port 53 is open and is not being blocked by my ISP. It can see services on this port. Registered Domain name (mydomain.com.au) Updated whois database through the domain registrars site and registered NameServer names: ns0.mydomain.com.au and ns2.mydomain.com.au, both have been associated with my single public IP. (Waited 24 hours) Update the nameserver for mydomain.com.au: primary ns0.mydomain.com.au secondary: ns2.mydomain.com.au (waited 24+ hours) Installed Server 2008 R2, install web server role and DNS role. Webserver works when I enter my public IP into browser of any PC/mobile, get IIS7 welcome page. In DNS server: Created new forward lookup zone: ; ; Database file mydoman.com.au.dns for mydomain.com.au zone. ; Zone version: 10 ; @ IN SOA mydomain.com.au. mydomain.testdomain.com.

• Ubuntu 11.10 firewall/gateway - no client internet access

I tried to be as thorough as possible but please let me know if I have missed something. Thank you!

• Some Memory Slots Not Working on MSI FM2-A85XA-G65 Motherboard

  - by Mike Ciaraldi

  Short version of question: Does anyone have an MSI FM2-A85XA-G65 motherboard, who can confirm that all four memory slots work? Long version: Several months ago I bought an MSI FM2-A85XA-G65 motherboard at Newegg. At that point I installed an AMD A8-5500 processor and two sticks of Corsair Vengeance 8 GB DDR3-1866 memory, and put it into my file server. I installed the RAM in slots 1 and 3, as directed in the manual, to enable dual-channel memory access. It seemed to work fine, so I bought a second identical mobo (which arrived dead, but was quickly replaced by Newegg) and set of RAM, installed an A10-5800K, and put that into my production Linux machine. Again, it seemed to work well. Eventually I happened to notice that on the server only 8 GB of RAM appeared in the BIOS. I tried each of the slots and memory modules individually and in various combinations. I even swapped processors with the production machine. The result was that putting memory in slots 1 and 2 worked (showing a total of 16 GB), but any memory in slots 3 or 4 was not recognized. However, all four memory slots in the production machine worked, and I confirmed this with both processors. I contacted MSI and arranged to ship the defective mobo back to them for replacement under warranty. I did not want my file server to be down in the interim, and I had another machine I wanted to upgrade, so I bought a third identical mobo to use. That one had the same problem -- only memory slots 1 and 2 worked. I tested it thoroughly with multiple processors and memory sticks. I sent the defective mobo back to MSI and they sent me a new one. This has the same memory slot problem. So I sent it back. The replacement arrived the other day and shows the same problem. I contacted MSI yet again and they said that nobody else has reported memory slot problems on this board and it must be my processor. So my score so far is, out of six boards of this model, I have: One where all four slots work. One which was dead on arrival. Four where only memory slots 1 and 2 work. Before I tear my other machines apart and start swapping processors again I thought I would ask if anyone else has this exact model motherboard and could confirm that all four memory slots either do or do not work. According to MSI you should be able to just plug a single memory module into any of the slots and it will work (and it does on the one mobo I have which works correctly). If you have not yet used all four slots, this is a good time to test them so you know if you can expand your memory in the future. Thanks in advance to anyone who can help.

• Dlink search is hijacking my browser

  - by James

  For months now "DLink search" has been hijacking my search engines. I use google chrome, and I have organized my search engines in the handy dandy "manage search engines" tool about a TRILLION times. It never even says D-link is hacking my search engines. It does not show up! I have read many posts on this forum and others saying that to fix this problem from internet explorer: Setup, internet options, yadayada, magical fairies, and you are solved, but my browser is google chrome! How am I supposed to do this from there! I do not know how to re-setup my Dlink router, which is the cause of the problem! HOW? In those posts with the magical fairies fixing it, HUNDREDS responded saying, "yep, those fairies definitely fixed it right. :)" These people were so satisfied. IT WORKED FOR THEM, WHY NOT ME. I look at it and go ":(" because it does not help me. There are no options for anything to do with this in GOOGLE chrome. PLEASE EXPLAIN and HELP. I see no "SETUP" option, no "Internet Options" button, no anything. BTW the exact posts are these: "Uncheck Advanced DNS in the router internet setup. This will take care of it. I had this problem with my DLink router before." "I had this issue with my DIR-655 and unchecking the Advanced DNS setting in Setup - Internet - Manual Internet Connection Setup fixed it." "If this is just internet explorer, you can go to Tools Internet Options or Internet Options in Control Panel. From here, go to the advanced tab and click the Reset button." "I would set the router's DNS to a site like OpenDNS, and I would ensure the machines are set to get their DNS settings via DHCP or set the machine's DNS setting to OpenDNS. If the router's DNS looks like it was messed with, some bad software know the default passwords for routers and could have changed it. If you don't already I would make sure the password to the router is not default or easy to guess. I've had spyware change a machine's DNS, but the fact it is happening on all machines makes me wonder if it is the router." "Something got into your router and changed the dns server most likely, do a hard reset of the router and then change the password to something strong. Also check for a firmware update for the router and apply it as soon as possible."

• Can I use one virtualbox disk for multiple machines?

  - by mxp

  I'm not sure what search term to use and skimming through the VirtualBox manual didn't help me either, so I ask my two questions here... My setup is this: PC with dual boot into Windows 7 and a Debian operating system (both 64bit). I've created a virtual machine (Kubuntu, 64bit) under Windows and put it's VDI file on a SMB share of my NAS. Then I created a VM under linux using the same settings for memory etc and assigned the existing VDI file to it. My idea was that I could use that virtual machine from Windows and Linux as well. (1) Is this generally something that should work without problems? I noticed that snapshots get me into trouble because they appear to be not visible from the other operating system: The snapshots I took after installing the guest system are not visible under Linux. That's why I shut down the VM after usage and not save its state while it's running. My current problem is this: I have used the VM under Windows first, then under Linux. Now it will only start on Linux. When trying this on Windows the guest OS detects some kind of hard disk error and fails to boot because it cannot mount its drive. Obviously the virtual hard disk won't fail so it must have something to do with me using it under Linux. (2) How can I fix that? Update: It also looks like any changes I made in the VM under Linux have been reset by trying to boot it under Windows. Looks like it's back to the latest snapshot. I'm confused... Update The answer to my first question can be found below. In short: It works, as long as you don't use snapshots. The answer to my second question is this: Under Windows set the VM back to the latest snapshot and then discard the snapshot so it gets merged. There should be no snapshots left at the end. If you have multiple snapshots, discard the earliest ones first (Snapshot 1, then 2, 3, ...). I'm not sure what happens if you start at the end (.., 3, 2, 1). This of course leads to some data loss since you revert all changes since the last snapshot. But at least the VM is usable again.

• Trying to grok Linux quotas, where is the data stored?

  - by CarpeNoctem

  So all the tutorials and documentation for the Linux quota system has left me confused. For each filesystem with quotas enabled/on where is the actual quota information stored? Is it filesystem metadata or is it in a file? Say user foo creates a new file on /home. How does the kernel determine whether user foo is below their hard limit? Does the kernel have to tally up quota information on that filesystem each time or is it in the superblock or somewhere else? As far as I understand, the kernel consults the aquota.user file for the actual rules, but where is the current quota usage data stored? Can this be viewed with any tools outside repquota and the like? TIA!! Update: Thanks for the help. I had already read that mini-HOWTO. I am pretty clear on the usage of the user space tools. What I was unclear on is whether the usage data was ALSO in the file that stored per-user limits and you answered this with a yes. From what I can tell, rc.sysinit runs quotacheck and quotaon on startup. The quotacheck program analyzes the filesystem, updates the aquota.* files. It then makes use of quota.h and the quotactl() syscall to inform the kernel of quota info. From this point forward the kernel hashes that information and increments/decrements quota stats as changes occur. Upon shutdown, the init.d/halt script runs the quotaoff command RIGHT before the filesystems are unmounted. The quotaoff command does not appear to update the aquota.* files with the information the kernel has in memory. I say this because the {a,c,m}times for the aquota.user file are only updated upon a reboot of the system or by manual running the quotacheck command. It appears - as far as I can tell - that the kernel just drops it's up-to-date usage data on the floor at shutdown. This information is never used to update the aquota.* files. They are updated during startup by quotacheck(rc.sysinit). Seems silly to me since that updated info had already been collected by the kernel. So...in conclusion I am still not entirely clear on the methods. ;)

• Is this iptables NAT exploitable from the external side?

  - by Karma Fusebox

  Could you please have a short look on this simple iptables/NAT-Setup, I believe it has a fairly serious security issue (due to being too simple). On this network there is one internet-connected machine (running Debian Squeeze/2.6.32-5 with iptables 1.4.8) acting as NAT/Gateway for the handful of clients in 192.168/24. The machine has two NICs: eth0: internet-faced eth1: LAN-faced, 192.168.0.1, the default GW for 192.168/24 Routing table is two-NICs-default without manual changes: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 (externalNet) 0.0.0.0 255.255.252.0 U 0 0 0 eth0 0.0.0.0 (externalGW) 0.0.0.0 UG 0 0 0 eth0 The NAT is then enabled only and merely by these actions, there are no more iptables rules: echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # (all iptables policies are ACCEPT) This does the job, but I miss several things here which I believe could be a security issue: there is no restriction about allowed source interfaces or source networks at all there is no firewalling part such as: (set policies to DROP) /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT And thus, the questions of my sleepless nights are: Is this NAT-service available to anyone in the world who sets this machine as his default gateway? I'd say yes it is, because there is nothing indicating that an incoming external connection (via eth0) should be handled any different than an incoming internal connection (via eth1) as long as the output-interface is eth0 - and routing-wise that holds true for both external und internal clients that want to access the internet. So if I am right, anyone could use this machine as open proxy by having his packets NATted here. So please tell me if that's right or why it is not. As a "hotfix" I have added a "-s 192.168.0.0/24" option to the NAT-starting command. I would like to know if not using this option was indeed a security issue or just irrelevant thanks to some mechanism I am not aware of. As the policies are all ACCEPT, there is currently no restriction on forwarding eth1 to eth0 (internal to external). But what are the effective implications of currently NOT having the restriction that only RELATED and ESTABLISHED states are forwarded from eth0 to eth1 (external to internal)? In other words, should I rather change the policies to DROP and apply the two "firewalling" rules I mentioned above or is the lack of them not affecting security? Thanks for clarification!

• QNAP (469L) with Debian: can't connect to router

  - by agtoever

  I've been running my QNAP 469L with Debian (Wheezy deb7u3) for a few months. Yesterday I upgraded the memory to 4 GB. The system boots fine, but since the upgrade, I'm not able to connect the server to my router (a TP-Link WR941ND). My configuration: The router runs a DHCP server (192.168.67.100 and up), with a preconfigured ip address for the QNAP (192.168.67.10). The router is on 192.168.67.1. As said, Debian is installed on the QNAP (which can be regarded as a normal computer). Networking hardware on the QNAP: Intel PRO/1000 Network Connection using the e1000e kernel module. This is what I have tried so far: Replace the network cable (tried 3 different cables on different router ports). Check for messages from the kernel: dmesg | grep eth. Besides the normal hardware messages I get a ADDRCONF(NETDEV_UP): eth0: link is not ready for each call to ifup. Manually restart the network sudo server networking restart Check sudo ifconfig (eth0 is up, but no ip addresses). Check the /etc/network/interfaces which has (besides the loopback device) an allow-hotplug eth0 and iface eth0 inet dhcp, which is afaik the default Debian configuration. Since the server has two ethernet ports, I checked if I'm using the right port (checked the hardware address that ifconfig reports for eth0 is the same as the hardware address that is in the preconfigured ip address for the server in the router. Do a manual sudo ifdown eth0 && sudo ifup eth0 with no results (but an extra ADDRCONF(NETDEV_UP): eth0: link is not ready in the kernel log) Do a dhcp request dhclient -v eth0: for about a minute requests are send (according to the terminal) and at the end I get a No DHCPOFFERS received. No working leases in persistent database - sleeping.. Check the router system log if DHCP requests are received. I see them for some devices (my Mac, my iPhone) but not from the QNAP. The log entry looks like: DHCPS:Recv REQUEST from 84:85:06:07:75:6A and then a DHCPS:Send ACK to 192.168.67.101. There are no records from the QNAP's hardware address. So the two error messages that I do get are: ADDRCONF(NETDEV_UP): eth0: link is not ready for every ifup and No DHCPOFFERS received. No working leases in persistent database - sleeping. for every DHCP call.

• Wifi network stopped being visible (and usable) (Linksys wag320n)

  - by s427

  Basically, my wifi network simply stopped working for no apparent reason. It doesn't appear in the list of the available networks anymore. I can see all my neighbors' networks, but not mine. It's as if it doesn't exist anymore. The internet connection (non-wifi), which goes through the same modem/router, is fine though. I already had a similar problem about one year ago (see here: Wifi network SSID not visible ), just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the Cisco "Magic" software; but this time it's not working. I use a linksys router-modem (WAG320N) which is directly connected (via network cable) to my desktop computer (Windows 7). I have (mainly) two devices that use the wifi network: my phone (Samsung Galaxy Nexus) and an Asus tablet (TF201, aka Transformer Prime). I also resurrected an old laptop computer (Dell, running Windows XP) to test that, and it doesn't see anything either (apart from the 20 other wifi networks, of course ^^). This wifi network was working just fine and has been for about a year. I haven't touched the modem settings so I have no idea what's causing the problem. I tried: making my phone "forget" about my network, hoping it would see it again after that: no luck. re-entering the network informations (SSID/password) manually on my phone: still no luck (says it's not in range) exporting the modem configuration, resetting the modem (factory reset, via modem admin), restarting it, importing the configuration: nope. factory reset, turning it off for 15 minutes, restarting, re-factory reset, and entering the configuration manually: still nothing. Has anybody experienced something similar before? Have you any suggestion to fix that? Thanks in advance. PS: to clear things up, here are the settings of my modem regarding wifi: Basic wireless settings: Configuration: manual Radio Band: 2.4GHz Wireless Network Mode: B/G/N-Mixed SSID: s427 Channel Bandwidth: Wide - 40 MHz Channel Wide Channel: 9 - 2.452GHz Standard Channel: 11 - 2.462GHz SSID Broadcast: Enable Advanced Wireless Settings AP Isolation: Disable Authentication Type: Auto Basic Rate: Default Transmission Rate: Auto N Transmission Rate: Auto CTS Protection Mode: Disable Beacon Interval: 100 DTIM Interval: 1 Fragmentation Threshold: 2346 RTS Threshold: 2346

A couple of the tools have a WebLogic Scripting Tool or 'WLST' interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here.

For access to the Oracle demo systems please visit OPN and talk to your Partner Expert DSS is pleased to announce the availability of the demo “Business Driven Development“. This innovative demonstration uses a case-study approach to show business users how they can easily streamline their Business Processes - delivering greater efficiency, agility, visibility and collaboration with Oracle BPM and WebCenter. The BDD demonstration uses a case study-based approach to highlight a business problem at a fictional company, Avitek Corporation, and uses Oracle BPM and Oracle WebCenter to solve the business problem. This holistic approach has specifically been used to appeal to a non-technical business analyst user. This demo is NOT focused on product features, but aims to guide users through a complete BPM lifecycle. The scenario is based on improving a simple order process (scenario details are in the demo script). Avitek Corporation is sufferinng from a manual email-driven ordering process. Sales reps don’t know where the customer orders are stuck (no visibility) and finance users are unable to manually approve every order (no automation). There are several areas where this process can be improved with Business Process Management technology. This demo shows how improving following areas will ignificantly help resolve the business problems Avitek Corporation is facing. Areas for improvement include: Utilizing BPM for process management, rather than an unregulated, email-based process. Utilizing automated services, rather than requiring a human to key into a system. For example, Finance checking the customer’s credit rating is something that could be automated. Centralizing business rules that can be integrated into a business process, rather than requiring a human to process them. For example, Finance must determine when orders can be automatically approved. Provide insight and visibility into the process. For example, Sales Rep needs to know the status of their customer’s orders. The BDD Demo uses the following products.

• Building a database installer with WiX, datadude and Visual Studio 2010

  - by jamiet

  Today I have been using Windows Installer XML (WiX) to build an installer (.msi file) that would install a SQL Server database on a server of my choosing; the source code for that database lives in datadude (a tool which you may know by one of quite a few other names). The basis for this work was a most excellent blog post by Duke Kamstra entitled Implementing a WIX installer that calls the GDR version of VSDBCMD.EXE which coves the delicate intricacies of doing this – particularly how to call Vsdbcmd.exe in a CustomAction. Unfortunately there are a couple of things wrong with Duke’s post: Searching for “datadude wix” didn’t turn it up in the first page of search results and hence it took me a long time to find it. And I knew that it existed. If someone else were after a post on using WiX with datadude its likely that they would never have come across Duke’s post and that would be a great shame because its the definitive post on the matter. It was written in October 2009 and had not been updated for Visual Studio 2010. Well, this blog post is an attempt to solve those problems. Hopefully I’ve solved the first one just by following a few of my blogging SEO tips while writing this blog post, in the rest of it I will explain how I took Duke’s code and updated it to work in Visual Studio 2010. If you need to build a database installer using WiX, datadude and Visual Studio 2010 then you still need to follow Duke’s blog post so go and do that now. Below are the amendments that I made that enabled the project to get built in Visual Studio 2010: In VS2010 datadude’s output files have changed from being called Database.<suffix> to <ProjectName>_Database.<suffix>. Duke’s code was referencing the old file name formats. Duke used $(var.SolutionDir) and relative paths to point to datadude artefacts I have replaced these with Votive Project References http://wix.sourceforge.net/manual-wix3/votive_project_references.htm I commented out all references to MicrosoftSqlTypesDbschema in DatabaseArtifacts.wxi. I don't think this is produced in VS2010 (I may be wrong about that but it wasn't in the output from my project) Similarly I commented out component MicrosoftSqlTypesDbschema in VsdbcmdArtifacts.wxi. It wasn't where Duke's code said it should have been so am assuming/hoping it isn't needed. Duke's ?define block to work out appropriate SrcArchPath actually wasn't working for me (i.e. <?if $(var.Platform)=x64 ?> was evaluating to false)  so I just took out the conditional stuff and declared the path explicitly to the “Program Files (x86)” path. The old code is still there though if you need to put it back. None of the <RegistrySearch> stuff is needed for VS2010 - so I commented it all out! Changed to use /manifest option rather than /model option on vsdbcmd.exe command-line. Personal preference is all! Added a new component in order to bundle along the vsdbcmd.exe.config file Made the install of the Custom Action dependent on the relevant feature being selected for install. This one is actually really important – deselecting the database feature for installation does not, by default, stop the CustomAction from executing and so would cause an error - so that scenario needs to be catered for I have made my amended solution available for download at: http://cid-550f681dad532637.office.live.com/self.aspx/Public/BlogShare/20110210/InstallMyDatabase.zip It contains two projects: the WiX project and the datadude project that is the source to be deployed (for demo purposes it only contains one table). I have also made the .msi available although in order that it gets through file blockers I changed the name from InstallMyDatabase.msi to InstallMyDatabase.ms_ – simply rename the file back once you have downloaded it from: http://cid-550f681dad532637.office.live.com/self.aspx/Public/BlogShare/20110210/InstallMyDatabase.ms%5E_ .You can try it out for yourself – the only thing it does is dump the files into %Program Files%\MyDatabase and uses them to install a database onto a server of your choosing with a name of your choosing - no damaging side-affects. I will caveat this by saying “it works on my machine” and, not having access to a plethora of different machines, I haven’t tested it anywhere else. One potential issue that I know of is that Vsdbcmd.exe has a dependency on SQL Server CE although if you have SQL Server tools or Visual Studio installed you should be fine. Unfortunately its not possible to bundle along the SQL Server CE installer in the .msi because Windows will not allow you to call one installer from inside another – the recommended way to get around this problem is to build a bootstrapper to bundle the whole lot together but doing that is outside the scope of this blog post. If you discover any other issues then please let me know. Here are the screenshots from the installer: And once installed…. Hope this is useful! @jamiet

• Test Drive Windows 7 Online with Virtual Labs

  - by Matthew Guay

  Did you miss out on the Windows 7 public beta and want to try it out before you actually make the leap and upgrade? Maybe you want to learn how to deploy new features in a business environment. Here’s how you can test drive Windows 7 directly from your browser. Whether you manage 10,000 desktops or simply manage your own laptop, it’s usually best to test out a new OS before installing it.  If you’re upgrading from Windows XP you may find many things unfamiliar.  Microsoft has setup a special Windows 7 Test Drive website with resources to help IT professionals test and deploy Windows 7 in their workplaces.  This is a great resource to try out Windows 7 from the comfort of your browser, and look at some of the new features without even installing it. Please note that the online version is not nearly as responsive as a full standard install of Windows 7.  It also does not run the full Aero interface or desktop effects, and may refresh slowly depending on your Internet connection.  So don’t judge Windows 7’s performance based on this virtual lab, but use it as a way to learn more about Windows 7 without installing it. Getting Started To test drive Windows 7, visit Microsoft’s Windows 7 Test Drive website (link below).  You will need to run the Windows 7 Test Drive in Internet Explorer, as it requires Active X support.  We received this error when attempting to run the Test Drive in Firefox: Now, click the “Take a Test Drive” link on the bottom left of the page. This site includes several test drives to demonstrate different features of Windows 7 and its related ecosystem of products including Windows Server 2008 R2, some of which, including the XP Mode test drive, are not yet ready.  For this test, we selected the MED-V Test drive, as this includes Office 2007 and 2010 so you can test them in Windows 7 as well.  Simply select the test drive you want, and click “Try it now!”   If you haven’t run a Windows test drive before, you will be asked to install an ActiveX control.  Click the link to install. Click the yellow bar at the top of the page in Internet Explorer, and select to Install the add-on.  You may have to approve a UAC prompt to finish the install. Once this is finished, click the link on the bottom of the page to return to your test drive.  The test drive page should automatically refresh; if it doesn’t, click refresh to reload it. Now the test drive will load the components.   Once its fully loaded, click the link to launch Windows 7 in a new window. You may see a prompt warning that the server may have been impersonated.  Simply click Yes to proceed. The test lab will give you some getting started directions; click Close Window when you’re ready to try out Windows 7. Here’s the default desktop in the Windows 7 test drive.  You can use it just like a normal Windows computer, but do note that it may function slowly depending on your internet connection.   This test drive includes both Office 2007 and Office 2010 Tech Preview, so you can try out both in Windows 7 as well. You can try out the new Windows 7 applications such as the reworked Paint with the Ribbon interface from Office. Or you can even test the newest version of Media Center, though it will warn you that it may not function good with the down-scaled graphics in the test drive.   Most importantly, you can try out the new features in Windows 7, such as Jumplists and even Aero Snap.  Once again, these features will not function the quickest, but it does let you test them out. While working with the Virtual Lab, there are different tasks it walks you through. You can also download a copy of the lab manual in PDF format to help you navigate through the various objectives. The test drive system is running Microsoft Forefront Security, the enterprise security solution from which Microsoft Security Essentials has adapted components from. Conclusion These virtual labs are great for tech students, or those of you who want to get a first-hand trial of the new features. Also, if you’re not sure on how to deploy something and want to practice in a virtual environment, these labs are quite valuable.While these labs are geared toward IT professionals, it’s a good way for anyone to try out Windows 7 features from the comfort of your current computer.

• jQuery 1.4 Opacity and IE Filters

  - by Rick Strahl

  Ran into a small problem today with my client side jQuery library after switching to jQuery 1.4. I ran into a problem with a shadow plugin that I use to provide drop shadows for absolute elements – for Mozilla WebKit browsers the –moz-box-shadow and –webkit-box-shadow CSS attributes are used but for IE a manual element is created to provide the shadow that underlays the original element along with a blur filter to provide the fuzziness in the shadow. Some of the key pieces are: var vis = el.is(":visible"); if (!vis) el.show(); // must be visible to get .position var pos = el.position(); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); This has always worked in previous versions of jQuery, but with 1.4 the original filter no longer works. It appears that applying the opacity after the original filter wipes out the original filter. IOW, the opacity filter is not applied incrementally, but absolutely which is a real bummer. Luckily the workaround is relatively easy by just switching the order in which the opacity and filter are applied. If I apply the blur after the opacity I get my correct behavior back with both opacity: sh.show() .css({ position: "absolute", width: el.outerWidth(), height: el.outerHeight(), opacity: opt.opacity, background: opt.color, left: pos.left + opt.offset, top: pos.top + opt.offset }); if (typeof shEl.style.filter == "string") sh.css("filter", 'progid:DXImageTransform.Microsoft.Blur(makeShadow=true, pixelradius=3, shadowOpacity=' + opt.opacity.toString() + ')'); While this works this still causes problems in other areas where opacity is implicitly set in code such as for fade operations or in the case of my shadow component the style/property watcher that keeps the shadow and main object linked. Both of these may set the opacity explicitly and that is still broken as it will effectively kill the blur filter. This seems like a really strange design decision by the jQuery team, since clearly the jquery css function does the right thing for setting filters. Internally however, the opacity setting doesn’t use .css instead hardcoding the filter which given jQuery’s usual flexibility and smart code seems really inappropriate. The following is from jQuery.js 1.4: var style = elem.style || elem, set = value !== undefined; // IE uses filters for opacity if ( !jQuery.support.opacity && name === "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level style.zoom = 1; // Set the alpha filter to set the opacity var opacity = parseInt( value, 10 ) + "" === "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"; var filter = style.filter || jQuery.curCSS( elem, "filter" ) || ""; style.filter = ralpha.test(filter) ? filter.replace(ralpha, opacity) : opacity; } return style.filter && style.filter.indexOf("opacity=") >= 0 ? (parseFloat( ropacity.exec(style.filter)[1] ) / 100) + "": ""; } You can see here that the style is explicitly set in code rather than relying on $.css() to assign the value resulting in the old filter getting wiped out. jQuery 1.32 looks a little different: // IE uses filters for opacity if ( !jQuery.support.opacity && name == "opacity" ) { if ( set ) { // IE has trouble with opacity if it does not have layout // Force it by setting the zoom level elem.zoom = 1; // Set the alpha filter to set the opacity elem.filter = (elem.filter || "").replace( /alpha\([^)]*\)/, "" ) + (parseInt( value ) + '' == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"); } return elem.filter && elem.filter.indexOf("opacity=") >= 0 ? (parseFloat( elem.filter.match(/opacity=([^)]*)/)[1] ) / 100) + '': ""; } Offhand I’m not sure why the latter works better since it too is assigning the filter. However, when checking with the IE script debugger I can see that there are actually a couple of filter tags assigned when using jQuery 1.32 but only one when I use jQuery 1.4. Note also that the jQuery 1.3 compatibility plugin for jQUery 1.4 doesn’t address this issue either.

• Create a Persistent Bootable Ubuntu USB Flash Drive

  - by Trevor Bekolay

  Don’t feel like reinstalling an antivirus program every time you boot up your Ubuntu flash drive? We’ll show you how to create a bootable Ubuntu flash drive that will remember your settings, installed programs, and more! Previously, we showed you how to create a bootable Ubuntu flash drive that would reset to its initial state every time you booted it up. This is great if you’re worried about messing something up, and want to start fresh every time you start tinkering with Ubuntu. However, if you’re using the Ubuntu flash drive to diagnose and solve problems with your PC, you might find that a lot of problems require guess-and-test cycles. It would be great if the settings you change in Ubuntu and the programs you install stay installed the next time you boot it up. Fortunately, Universal USB Installer, a great little program from Pen Drive Linux, can do just that! Note: You will need a USB drive at least 2 GB large. Make sure you back up any files on the flash drive because this process will format the drive, removing any files currently on it. Once Ubuntu has been installed on the flash drive, you can move those files back if there is enough space. Put Ubuntu on your flash drive Universal-USB-Installer.exe does not need to be installed, so just double click on it to run it wherever you downloaded it. Click Yes if you get a UAC prompt, and you will be greeted with this window. Click I Agree. In the drop-down box on the next screen, select Ubuntu 9.10 Desktop i386. Don’t worry if you normally use 64-bit operating systems – the 32-bit version of Ubuntu 9.10 will still work fine. Some useful tools do not have 64-bit versions, so unless you’re planning on switching to Ubuntu permanently, the 32-bit version will work best. If you don’t have a copy of the Ubuntu 9.10 CD downloaded, then click on the checkbox to Download the ISO. You’ll be prompted to launch a web browser; click Yes. The download should start immediately. When it’s finished, return the the Universal USB Installer and click on Browse to navigate to the ISO file you just downloaded. Click OK and the text field will be populated with the path to the ISO file. Select the drive letter that corresponds to the flash drive that you would like to use from the dropdown box. If you’ve backed up the files on this drive, we recommend checking the box to format the drive. Finally, you have to choose how much space you would like to set aside for the settings and programs that will be stored on the flash drive. Considering that Ubuntu itself only takes up around 700 MB, 1 GB should be plenty, but we’re choosing 2 GB in this example because we have lots of space on this USB drive. Click on the Create button and then make yourself a sandwich – it will take some time to install no matter how fast your PC is. Eventually it will finish. Click Close. Now you have a flash drive that will boot into a fully capable Ubuntu installation, and any changes you make will persist the next time you boot it up! Boot into Ubuntu If you’re not sure how to set your computer to boot using the USB drive, then check out the How to Boot Into Ubuntu section of our previous article on creating bootable USB drives, or refer to your motherboard’s manual. Once your computer is set to boot using the USB drive, you’ll be greeted with splash screen with some options. Press Enter to boot into Ubuntu. The first time you do this, it may take some time to boot up. Fortunately, we’ve found that the process speeds up on subsequent boots. You’ll be greeted with the Ubuntu desktop. Now, if you change settings like the desktop resolution, or install a program, those changes will be permanently stored on the USB drive! We installed avast! Antivirus, and on the next boot, found that it was still in the Accessories menu where we left it. Conclusion We think that a bootable Ubuntu USB flash drive is a great tool to have around in case your PC has problems booting otherwise. By having the changes you make persist, you can customize your Ubuntu installation to be the ultimate computer repair toolkit!

• Adopting DBVCS

  - by Wes McClure

  Identify early adopters Pick a small project with a small(ish) team.  This can be a legacy application or a green-field application. Strive to find a team of early adopters that will be eager to try something new. Get the team on board! Research Research the tool(s) that you want to use.  Some tools provide all of the features you would need while some only provide a slice of the pie.  DBVCS requires the ability to manage a set of change scripts that update a database from one version to the next.  Ideally a tool can track database versions and automatically apply updates.  The change script generation process can be manual, but having diff tools available to automatically generate it can really reduce the overhead to adoption.  Finally, an automated tool to generate a script file per database object is an added bonus as your version control system can quickly identify what was changed in a commit (add/del/modify), just like with code changes. Don’t settle on just one tool, identify several.  Then work with the team to evaluate the tools.  Have the team do some tests of the following scenarios with each tool: Baseline an existing database: can the migration tool work with legacy databases?  Caution: most migration platforms do not support baselines or have poor support, especially the fad of fluent APIs. Add/drop tables Add/drop procedures/functions/views Alter tables (rename columns, add columns, remove columns) Massage data – migrations sometimes involve changing data types that cannot be implicitly casted and require you to decide how the data is explicitly cast to the new type.  This is a requirement for a migrations platform.  Think about a case where you might want to combine fields, or move a field from one table to another, you wouldn’t want to lose the data. Run the tool via the command line.  If you cannot automate the tool in Continuous Integration what is the point? Create a copy of a database on demand. Backup/restore databases locally. Let the team give feedback and decide together, what tool they would like to try out. My recommendation at this point would be to include TSqlMigrations and RoundHouse as SQL based migration platforms.  In general I would recommend staying away from the fluent platforms as they often lack baseline capabilities and add overhead to learn a new API when SQL is already a very well known DSL.  Code migrations often get messy with procedures/views/functions as these have to be created with SQL and aren’t cross platform anyways.  IMO stick to SQL based migrations. Reconciling Production If your project is a legacy application, you will need to reconcile the current state of production with your development databases.  Find changes in production and bring them down to development, even if they are old and need to be removed.  Once complete, produce a baseline of either dev or prod as they are now in sync.  Commit this to your VCS of choice. Add whatever schema changes tracking mechanism your tool requires to your development database.  This often requires adding a table to track the schema version of that database.  Your tool should support doing this for you.  You can add this table to production when you do your next release. Script out any changes currently in dev.  Remove production artifacts that you brought down during reconciliation.  Add change scripts for any outstanding changes in dev since the last production release.  Commit these to your repository.   Say No to Shared Dev DBs Simply put, you wouldn’t dream of sharing a code checkout, why would you share a development database?  If you have a shared dev database, back it up, distribute the backups and take the shared version offline (including the dev db server once all projects are using DB VCS).  Doing DB VCS with a shared database is bound to cause problems as people won’t be able to easily script out their own changes from those that others are working on.   First prod release Copy prod to your beta/testing environment.  Add the schema changes table (or mechanism) and do a test run of your changes.  If successful you can schedule this to be run on production.   Evaluation After your first release, evaluate the pain points of the process.  Try to find tools or modifications to existing tools to help fix them.  Don’t leave stones unturned, iteratively evolve your tools and practices to make the process as seamless as possible.  This is why I suggest open source alternatives.  Nothing is set in stone, a good example was adding transactional support to TSqlMigrations.  We ran into situations where an update would break a database, so I added a feature to do transactional updates and rollback on errors!  Another good example is generating change scripts.  We have been manually making these for months now.  I found an open source project called Open DB Diff and integrated this with TSqlMigrations.  These were things we just accepted at the time when we began adopting our tool set.  Once we became comfortable with the base functionality, it was time to start automating more of the process.  Just like anything else with development, never be afraid to try to find tools to make your job easier!   Enjoy -Wes

• WP7 “Phantom Data” Source Possibly Revealed?

  - by Bil Simser

  Recently there’s been rumours floating around regarding “phantom” Windows Phone 7 data being magically sent and received on the latest WP7 phones. The news has mostly been floating around twitter so I didn’t pay it much attention. The BBC Technology News picked it up so I thought I would look more into it myself seeing that we have WP7 phones and maybe there was some truth to all this (and more importantly what was the cause). Full disclosure. I don’t have a lot of data points around this. This is from looking at a few phone logs, changing the configuration and looking back again after the change. I haven’t done a clean baseline test nor have I done testing with hundreds of phones. I leave the experience up to the reader to decide. So I went spelunking into the phone logs to see what was up. Most providers will show you data usage, at least on a daily basis. I lucked out with the provider and plan in that they provide hourly breakdowns. Here’s a snapshot from my usage throughout one night. Timestamp Data Usage 12:38:30 AM 2098 Kilobytes 1:30:30 AM 2 Kilobytes 2:38:30 AM 7118 Kilobytes 3:38:30 AM 6622 Kilobytes 4:38:30 AM 76 Kilobytes 5:38:30 AM 29 Kilobytes 6:38:30 AM 19 Kilobytes 7:38:30 AM 20 Kilobytes So a few observations from this data: Data seems to be collected on a regular basis. Looking at some other people phone logs, the times vary but it’s always hourly. There’s not a tremendous amount of data here (about 16 megabytes) but it seems like a lot for 7 hours The phone was connected to my home Wifi during this period Nothing was running and the phone was in a locked state Like I said, not a lot of data but it adds up. 16MB for 7 hours = about 50MB in a 24 hour period. That’s just plain old data being collected (somewhere, somehow) and not actual usage (Marketplace, Email, Browsing, etc.). Besides, when connected to a WiFi network you shouldn’t be charged data usage from your phone company (in theory, YMMV). After reviewing the logs I made a theory that the only thing that could possibly be sending data is the Feedback feature. With no other apps running under lock, what else could it be? In Windows 7 under your Settings the last option is Feedback. This sends feedback to Microsoft to “help improve Windows Phone”. On this page you have three options: Send feedback and use my cellular data connection Send feedback and (presumably) use my WiFi connection Don’t send feedback Knowing what I know about Microsoft, they do use the feedback data. For example some of the placement and inclusion of features in Office 2007 was based on that Feedback data that Office sends (assuming you had opted in). However in the Privacy Statement (it’s long but a good read at least once in your life), the Phone manual, and every other source I could look at there is no information about how much data it’s planning to send, just that it’s sending some data and that “some data charges with your carrier may apply”. Looking back at the logs, I have to wonder. 6MB at 3:30 and *then* 7MB the next hour. That’s a lot of information. And it adds up. 50MB in a 24 hour period X 30 days puts most people over a normal 1GB plan. And frankly why am I paying for a data plan only to have 80% of it chewed up by Microsoft, with no real benefit to me. If they included porn in the 50mb daily transfer I’d be okay with this, but I don’t see any new movies on my phone. So I turned it off. Set Feedback to disabled and wait. I waited. And waited. And generally didn’t use the phone if I could. The next day I went back to look at the data usage logs from the time period after turning the feedback mechanism off. Here are the results. Timestamp Data Usage 1:19:48 PM 0 Kilobytes 2:19:48 PM 0 Kilobytes 3:19:48 PM 0 Kilobytes 4:19:48 PM 678 Kilobytes (took a phone call) 5:19:48 PM 82 Kilobytes 6:19:48 PM 88 Kilobytes 7:20:30 PM 86 Kilobytes (guess they changed their reporting time) 8:20:30 PM 86 Kilobytes 9:20:30 PM 66 Kilobytes 10:20:30 PM 67 Kilobytes 11:20:30 PM 49 Kilobytes 12:20:30 AM 32 Kilobytes 1:20:30 AM 38 Kilobytes 2:20:31 AM 18 Kilobytes 3:20:31 AM 27 Kilobytes 4:20:31 AM 86 Kilobytes 5:20:31 AM 53 Kilobytes 6:20:31 AM 22 Kilobytes 7:22:15 AM 30 Kilobytes (another reporting time change) 8:22:15 AM 29 Kilobytes 9:22:15 AM 74 Kilobytes 10:22:15 AM 154 Kilobytes (phone call) 11:22:15 AM 12 Kilobytes 12:13:27 PM 49 Kilobytes 1:13:27 PM 197 Kilobytes (phone call) Quite a *drastic* change from what Feedback was turned on. I mean for a 24 hour period (sans 3 phone calls) I consumed about 1MB. Still quite a bit of transfer going on but at least it amounts to 30MB per month, not 30MB per day! Like I said this observation is neither scientific or conclusive. You decide what to do but frankly until Microsoft makes this data transfer exempt from your data plan (like that will happen) I would just turn Feedback off. YMMV.

• PHP OCI8 and Oracle 11g DRCP Connection Pooling in Pictures

  - by christopher.jones

  Here is a screen shot from a PHP OCI8 connection pooling demo that I like to run. It graphically shows how little database host memory is needed when using DRCP connection pooling with Oracle Database 11g. Migrating to DRCP can be as simple as starting the pool and changing the connection string in your PHP application. The script that generated the data for this graph was a simple "Parts" query application being run under various simulated user loads. I was running the database on a small Oracle Linux server with just 2G of memory. I used PHP OCI8 1.4. Apache is in pre-fork mode, as needed for PHP. Each graph has time on the horizontal access in arbitrary 'tick' time units. Click the image to see it full sized. Pooled connections Beginning with the top left graph, At tick time 65 I used Apache's 'ab' tool to start 100 concurrent 'users' running the application. These users connected to the database using DRCP: $c = oci_pconnect('phpdemo', 'welcome', 'myhost/orcl:pooled'); A second hundred DRCP users were added to the system at tick 80 and a final hundred users added at tick 100. At about tick 110 I stopped the test and restarted Apache. This closed all the connections. The bottom left graph shows the number of statements being executed by the database per second, with some spikes for background database activity and some variability for this small test. Each extra batch of users adds another 'step' of load to the system. Looking at the top right Server Process graph shows the database server processes doing the query work for each web user. As user load is added, the DRCP server pool increases (in green). The pool is initially at its default size 4 and quickly ramps up to about (I'm guessing) 35. At tick time 100 the pool increases to my configured maximum of 40 processes. Those 40 processes are doing the query work for all 300 web users. When I stopped the test at tick 110, the pooled processes remained open waiting for more users to connect. If I had left the test quiet for the DRCP 'inactivity_timeout' period (300 seconds by default), the pool would have shrunk back to 4 processes. Looking at the bottom right, you can see the amount of memory being consumed by the database. During the initial quiet period about 500M of memory was in use. The absolute number is just an indication of my particular DB configuration. As the number of pooled processes increases, each process needs more memory. You can see the shape of the memory graph echoes the Server Process graph above it. Each of the 300 web users will also need a few kilobytes but this is almost too small to see on the graph. Non-pooled connections Compare the DRCP case with using 'dedicated server' processes. At tick 140 I started 100 web users who did not use pooled connections: $c = oci_pconnect('phpdemo', 'welcome', 'myhost/orcl'); This connection string change is the only difference between the two tests. At ticks 155 and 165 I started two more batches of 100 simulated users each. At about tick 195 I stopped the user load but left Apache running. Apache then gradually returned to its quiescent state, killing idle httpd processes and producing the downward slope at the right of the graphs as the persistent database connection in each Apache process was closed. The Executions per Second graph on the bottom left shows the same step increases as for the earlier DRCP case. The database is handling this load. But look at the number of Server processes on the top right graph. There is now a one-to-one correspondence between Apache/PHP processes and DB server processes. Each PHP processes has one DB server processes dedicated to it. Hence the term 'dedicated server'. The memory required on the database is proportional to all those database server processes started. Almost all my system's memory was consumed. I doubt it would have coped with any more user load. Summary Oracle Database 11g DRCP connection pooling significantly reduces database host memory requirements allow more system memory to be allocated for the SGA and allowing the system to scale to handled thousands of concurrent PHP users. Even for small systems, using DRCP allows more web users to be active. More information about PHP and DRCP can be found in the PHP Scalability and High Availability chapter of The Underground PHP and Oracle Manual.
