• How to have SSL on Amazon Elastic Load Balancer with a Gunicorn EC2 server?

  - by Riegie Godwin

  I'm a self taught back end engineer so I'm learning all of this stuff as I go along. For the longest time, I've been using basic authentication for my users. Many developers are advising against this approach since each request will contain the username & password in clear text. Anyone with the right skills can sniff on the connection between my iOS application and my Django/Gunicorn Server and obtain their password. I wouldn't want to put my user's credentials at risk so I would like to implement a more secure way of authentication. SSL seems to be the most viable option. My server doesn't serve any static content or anything crazy of that sort. All the server does is send and receive "json" responses from and to my iOS application. Here is my current topology. iOS application ------ Amazon Elastic Load Balancer ------- EC2 Instances running HTTP Gunicorn. Gunicorn runs on port 8000. I have a CNAME record from GoDaddy for the Amazon Elastic Load Balancer DNS. So instead of using the long DNS to make requests, I just use server.example.com. To interact with my servers I send and receive requests to server.example.com:8000/ This setup works and has been solid. However I need to have a more secure way. I would like to setup SSL between my iOS application and my Elastic Load Balancer. How can I go about doing this? Since I am only sending json responses to my application, do I really need to buy a certificate from a CA or can I create my own? (since browsers will not be interacting with my servers. My servers are only designed to send json responses to my iOS application).

• Oracle with Kerberos authentication and Windows 2003 Server as KDC

  - by Supaplex

  Hello everyone. I am running Oracle 10.2 on a Windows 2003 Server SP2 which is also the domain controller on the network. I wish to switch authentication method from NTS to Kerberos. I have spent a lot of time trying to configure Oracle with Kerberos authentication from the Oracle Advanced Security option from the Net Manager utility. I have disabled NTS so Kerberos is promoted as the preferred authentication method. But as soon as the configuration is saved from Net Manager and I restart the Oracle server service, Oracle will not start. I don't know what Oracle is complaining about, because I don't know where to look for the Oracle error log. My first question is: how can I figure out what's bugging Oracle? My second question: is there a good tutorial for setting up Oracle on a Windows 2003 with Kerberos Authentication, where the Windows 2003 Server is the KDC? Maybe there is a book I can get? I have read Oracles own guide, but it is mostly for Linux/Unix. Thanks a lot!

• Is it possible to provide a wired ethernet connection to external devices with an extra LAN card?

  - by Ben McCormack

  I'm trying to provide a wired ethernet connection (wireless is not an option for this device) to a device (Samsung blu-ray player) without running Cat5 cable all over the home. I have a PC sitting next to this device and the PC is connected to the network via a wireless USB adapter. Is it possible to provide a wired connection from the PC to the wired device using the (currently unused) ethernet port in the back of the computer? Here's how I envision the device getting connected to the internet via my network: Linksys WRT54G v8 Wireless Router | ``--> Windows 7 PC connected via wireless | ``--> Blu-ray player connected via wired connection to the ethernet port on the PC. If so, how is this done? Will I need a crossover cable? What settings will I need to change in Windows 7 so that the device can connect? NOTE: I'm trying to avoid having to buy a wireless bridge and/or hacking a router with an open-source firmware to get this to work. See my previous question for more details.

• Simple options for port forwarding to a different port?

  - by Nick

  I have three network printers at our local office, all of which listen on port 9100. Non of them offer the option of changing the listening port. We have a single public static IP address, and access to our main network is through a Linksys WRT-54G. We need to be able to print to these printers from outside the office. The problem is, with the 54G, I can only forward a port to the SAME port on a particular IP address. What I really need though is a way to forward to an ip address and a DIFFERENT port. I need to do this: In port Destination 9100 192.168.1.1 : 9100 9101 192.168.1.2 : 9100 9102 192.168.1.3 : 9100 So I'm looking for options. I could setup an old computer with two network cards and IPtables I suppose, but that seems like a lot of overhead for something relatively simple. Is there a way a virtual machine (read: one network card) could do the advanced port forwarding? Where I forward all traffic to it, and it forwards it on to the right printer? Or what about those mini Linux distros that replace the WRT-54G's firmware? Do any of those support what I need "out of the box"? I have a spare WRT- could I make it an IP tables router? Recommendations for mini distros? Or is there an off-the-shelf product that does this (cheap/local preferred)? Any advice / options appreciated. Thanks!

• Google Chrome doesn't delete my browsing history correctly

  - by Derfder

  I have deleted everything that I could from my browser history: chrome://settings/clearBrowserData I checked everything and select the begining of time Then when I access browsing history: chrome://history/ There is nothing (as I expected), or to be precise No history entries found. The problem is that I still see my specific search url with very specific query I have made a month ago, when I start typing the url of the website into chrome address bar. How is that possible? Where is Google stroing these data. How to get rid off them completely? I want to mention that my autosuggestion options look like this: So, what else should I delete to remove everything from autosuggestions? Right now it has some specific URLs (subpages, pages with very specific search query I have made in a month or so). I have tried restarting Chrome and restarting my computer, but the urls are still in the autosuggestion. Also I am unable to turn off the autosuggestion, even I have unchecked that option in settings. My Google Chrome version is: Version 27.0.1453.116 m (probably the latest) Btw. in Firefox deleting the history works as expected. So, I guess that this has nothing to do with the operating system I am using (Windows 7), but only it's an issue with Chrome itself.

• Can I recover a rm -rf-ed Mercurial repository?

  - by WishCow

  I made the mistake of wiping out my entire project directory with a quick "rm -rf project". Of course, the .hg directory went with it. I had about 15-20 changesets, that I have not pushed to anyone, and I would really really like to get those back. The system is a Ubuntu machine, and the partiton where the delete happened is ext3, the project consist mostly of PHP files. I know about the guideline to not write to the disk in question. The first idea was to use the tool named scalpel, to get the PHP files back and diff them with the current version from the repo, and somehow carve the changes out. While it succeeded, it did not recover the file names (or there is a switch I'm missing), so I'm left with a few thousand sequentially named .php files, combing through them is not an option. Can a kind soul please save me, and suggest a way to: a) get the repo back, or b) get the files back, with filenames For those wondering how I did such a stupid thing: I was working on a file in Vim which I wanted to remove from the repository: :!hg rm % This complained that the file is in a subrepository, so I specified the following: :!hg rm % -R engine which complained that file has modifications, use -f to force. And this is when somehow, I made up the following command: :!rm -rf % -R engine Somehow, seeing "force" makes me do a rm -rf by reflex.

• Will these instructions work when turning of journaling on a n ext4 SSD?

  - by snowlord

  I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions (from http://fenidik.blogspot.com/2010/03/ext4-disable-journal.html): # Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10 # Delete has_journal option tune2fs -O ^has_journal /dev/sda10 # Required fsck e2fsck -f /dev/sda10 # Check fs options dumpe2fs /dev/sda10 |more For more performance add fstab opions: data=writeback,noatime,nodiratime i.e: /dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0 I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

• pdo_mysql installation

  - by Arsenal

  Hello, On my server I'm trying to instal PHP Projekt (6). This requires pdo_mysql however. I thought this installation of pdo_mysql would be rather straightforward... I tried using pecl (pecl install pdo_mysql) after installing devel etc, but this came up with a permission denied error. I solved this by using directories that were accessible. It then came up with a cant run C compiled programs however. It also says to check config.log for more details but ironically config.log is automatically removed if the installation process fails... When I try to compile and output a "hello world".c however, it works perfectly. I then tried to download the pdo_mysql stuff and install in myself (using configure and make install). This seemed to do the job, but when I restarted my apache ... no sign of pdo_mysql anywhere even though I adjusted my php.ini file I have read somewhere that you need to recompile PHP with the option pdo_mysql enabled. But how does one do that (I'm using CentOS4). And isn't there any other way than that??? Thanks!

• Getting old bluetooth headset out of standby on Windows 7

  - by luagh45

  I think this is the problem, and if not, I'm open to suggestions. I have an old Jabra BT200 that I used to use on my phone. When a phone call was coming in it would beep using its own noises (meaning the phone never rang inside the headset) and then I could push the 'answer/hang up' button and sound and mic would start working. I have now paired it with Windows 7, and it looks good. Under the playback menu I have 'Bluetooth Hands free Audio / Jabra BT200 (Mono Audio) / Ready', and under the recording menu I have 'Bluetooth Audio Input Device / Jabra BT200 (Mono Audio) / Ready'. However when I try to test the speakers Windows sends a sound, but I never hear it, and when I talk in the mic, Windows never hears me. If I right click either the Bluetooth mic or speakers there's an option to 'Connect', but it's grayed out and I cannot click it. As the final piece of knowledge I have, my headset blinks once every 3 seconds when it's in standby and I can't get that to change. If everything was working it should blink once every second at which point I think all of my problems would be fixed. Hence my issue: I can't seem to get my headset out of standby. On my headset I've tried sending it test noises and then pressing the 'Answer' button, but still nothing. The headset beeps when I press it, so it works, it just doesn't ever come out of standby. Is there maybe some way to trick my headset into thinking it's getting a phone call from my computer?

• Setup Version Control on Dreamweaver

  - by John Isaacks

  I have a win computer on the Network called WIN2K8FS1 I have TortoiseSVN on a win computer and when I go to checkout a repository with Tortoise it asks me for the URL of the repository. I put in: file://WIN2K8FS1/Media/SVN_repo And it creates the working copy. I am trying to setup Dreamweaver CS5 to work with subversion. I create a new site and I go to the Version Control tab and it asks for a lot if info. First is Access. I choose Subversion since that is the only option Second is Protocol. Not sure which I need so I go with HTTP? Third is Server Address. I am assuming this is the name of the computer with the repository so I put in \\WIN2K8FS1\ Fourth is Repository Path. I put in /Media/SVN_repo Fifth is Port which I leave default to 80 Then it asks for user name and password. I never set one up for anything so I put in my domain username and password. I click test and it tells me: Server and project are not accessible! I am not sure what I am doing wrong. I am not the server admin but I did create the repository and have access to it via Tortoise. So I am not sure what I am doing wrong in Dreamweaver.

• Bypass proxy authentication [closed]

  - by Diego Queiroz

  My scenario: My network has a proxy that requires interative authentication. When I access any URL, an username and password is requested to enable navigation. I do have a valid username/password (this means I have permissions to access external content). I do not have access to the proxy server (any change to the proxy server is not an option). What I need: I need to bypass the interative authentication process and make it an automated authentication process. What I do NOT need/want: I do not need/want to hack the network. I do not need/want to access unauthorized content. In other words, I just need to find a way to "save" my password in the computer (security is not a problem) to allow application that does not support this kind of interative authentication to access the internet (like non-browser software that also uses HTTP port). My guess: My guess is to develop a new proxy server that will run in the local machine (eg, a proxy for the network proxy). This proxy server will access my network proxy, authenticate and forward the content. Of course this is a last resort. I prefer to not need to develop a proxy server. Does someone know other solution? (any operating system)

• Download JDK onto a remote server

  - by itsadok

  I want to get the latest JDK onto a server in a remote location. Downloading the JDK from Sun's website requires jumping through all kinds of hoops until you actually get the file. I'm not sure exactly if they use cookies or my IP address, but simply copying the file URL and trying wget on the server doesn't work. Googling for mirrors of the JDK, I could only find old versions. Right now I'm left with the option of downloading it into my computer, then uploading it to the server. This feels slow and stupid. Anyone got a better idea? EDIT: Thanks for all the replies. Just to clarify, as I'm writing this I'm rsyncing the 78MB file to my server. It should be done in about an hour, so it's not such a big deal. However, since this is not the first time I'm doing this, I was hoping for a better solution for next time. Solution: What I ended up doing was sudo aptitude install lynx-cur www-browser http://java.sun.com/javase/downloads/ From there it's mostly using the arrow and enter keys, and answering "Yes" to a lot of lynx security questions (about cookies and certificates). Thanks to resonator.

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• httpd 2.2.15 + suPHP + suExec + php5 = permission and information ?

  - by Prix

  Hi, i am currently playing around with suexec, suphp, php5 on my apache on slackware 13.1. Everything is installed and working properly but now i did like to got further into the directory permissions and at suphp settings and options available. initially i was planning to leave suphp disabled unless a virtualhost has it specified to be enabled but it does not seem to work, see sample: mod_php.conf which is included in my httpd.conf # # mod_php & mod_suPHP - PHP Hypertext Preprocessor module # # Load the PHP module: LoadModule php5_module lib/httpd/modules/libphp5.so # Load the suPHP module: LoadModule suphp_module lib/httpd/modules/mod_suphp.so <IfModule mod_php5.c> # Tell Apache to feed all *.php files through PHP. If you'd like to # parse PHP embedded in files with different extensions, comment out # these lines and see the example below. <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> </IfModule> <IfModule mod_suphp.c> # This option tells mod_suphp if a PHP-script requested on this server (or # VirtualHost) should be run with the PHP-interpreter or returned to the # browser "as it is". suPHP_Engine off </IfModule> With the above first sample it makes suPHP and PHP not work if i comment out the php5 stuff but the module it will run just fine ... So my first question is, how could i possible make this setup work ? Leave suPHP disabled using php5 by default and if a virtualhost has suPHP enabled it will disable php5 and use suPHP. if any information is lacked here please let me know and i will update with any additional information you may need. Thanks in advance.

• Why am I unable to reach local network computers, but able to browse the web?

  - by Igor Zinov'yev

  I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net. I have tried all of the below and it didn't help: Rebooting; Reconnecting to the network; Forcing the dhclient to renew the IP address; Deleting and creating new connection profiles; Plugging my machine into another network outlet; Maybe it has something to do with routing, because I have tampered with routing tables the day before, but the tables seem ok to me: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vboxnet0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 Our LAN uses a D-Link DI-604 router, and it looks to me as if I am connected to the network outside the router. I can not even access its administration page. Please at least suggest what I can do to solve this. P.S. What seems strangest to me is that I can access the PC in question from outside the network by opening a port on the router. I have managed to ssh to it from outside, but I still can't ping nothing on the inside. P.P.S Today I tried reinstalling network-manager with --purge option, but it did no good. After that I created a new DCHP reservation for my PC in order to change my local IP, but that didn't change anything either. My PC is able to get a DHCP offer, but then it's unable to connect to any local computers. I am desperate.

• Closing laptop lid and using external display causes mouse to move on it's own

  - by PolishHurricane

  I plugged my ASUS Taichi Laptop into an external monitor via the VGA Adapter that it comes with. It was working fine, but then I configured a power option so I could shut the lid without it going to sleep (so I could use just the external monitor with an external keyboard/mouse). Problem is though, now, when the lid is closed and I move the mouse, the mouse is moving around on it's own, but when I open the laptop lid back up, the mouse is fine. I looked under the lid when it was closed and the display properly shuts off on the laptop. It's not the external mouse/keyboard because I completely unplugged them and it was still happening. Nobody is hacking me or anything, I totally went into airplane mode/pulled the wire. I have a touchscreen, but I put a piece of paper over it and it wasn't doing it. I was thinking it might be the trackpad being touched somehow by the screen when the lid is closed? But I went into windows 8 control panel options and I couldn't find anywhere to disable it (it sees the USB mouse I think).

• Fully FOSS EMail solution

  - by Ravi

  I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

• Why are my socks proxies slow

  - by vps_newcomer

  I have a linux vps, and i have tried a few socks proxy setups to test their performance: All tests were using speedtest.net The standard ssh tunnel proxy 0.8mbit/s download and 0.1-0.2mbit/s upload speeds dante-server proxy 1.3mbit/s download and 0.4-0.5mbit/s upload I am wondering why are these speeds so slow? Is anything shaping them? Is it just the nature of socks proxies? I know that the ssh tunnel has to do encryption and what not so that is why its slow, but i was surprised to see that the second setup was also quite slow. On the VPS i have received download speeds of 25MB/s per second (thats about 200mbit/s and upload speed of atleast 5MB/s (haven't got a good enough pipe to test anything faster). The other option i was going to try is to setup OpenVPN and see how that goes, however i need to find a good tutorial as it's fairly complicated to setup. So why is it so slow? How can i test to see where the bottleneck is? How can i make it faster :D

• Using UDF on a USB flash drive

  - by CesarB

  After failing to copy a file bigger than 4G to my 8G USB flash drive, I formatted it as ext3. While this is working fine for me so far, it will cause problems if I want to use it to copy files to someone which does not use Linux. I am thinking of formatting it as UDF instead, which I hope would allow it to be read (and possibly even written) on the three most popular operating systems (Windows, MacOS, and Linux), without having to install any extra drivers. However, from what I found on the web already, there seem to be several small gotchas related to which parameters are used to create the filesystem, which can reduce the compability (but most of the pages I found are about optical media, not USB flash drives). I would like to know: Which utility should I use to create the filesystem? (So far I have found mkudffs and genisoimage, and mkudffs seems the best option.) Which parameters should I use with the chosen utility for maximum compability? How compatible with the most common versions of these three operating systems UDF actually is? Is using UDF actually the best idea? Is there another filesystem which would have better compatibility, with no problematic restrictions like the FAT32 4G file size limit, and without having to install special drivers in every single computer which touches it?

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• How do I boot [embedded] linux from sd card?

  - by Brandon Yates

  I am hacking together a quick embedded linux system on a DM816x evm board. Previously I have been using TFTP and NFS to load my kernel and root filesystem to the board. I am now trying to switch over to loading everything from an SD card. I have my card partitioned such that uBoot and my kernel image are in one partition, and my rootFS in another partition. At power-on, Uboot starts correctly and successfully launches the kernel. However, the kernel is unable to mount the root file system. It appears that it doesn't recognize any SD (mmc) cards. It gives this error message. VFS: Cannot open root device "mmcblk0p2" or unknown-block(2,0) Please append a correct "root=" boot option; here are the available partitions: 1f00 256 mtdblock0 (driver?) 1f01 8 mtdblock1 (driver?) 1f02 2560 mtdblock2 (driver?) 1f03 1272 mtdblock3 (driver?) 1f04 2432 mtdblock4 (driver?) 1f05 128 mtdblock5 (driver?) 1f06 4352 mtdblock6 (driver?) 1f07 204928 mtdblock7 (driver?) 1f08 50304 mtdblock8 (driver?) Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) I feel like I'm missing something fundamental here. Why does it not recognize the root device I am trying to load from?

• Postfix spool on ext3 optimiziations in >=linux-2.6.34 days

  - by Luke404

  Given the very specific nature of the subject (we're not talking about mailboxes, just the spool; we're not talking about other filesystems, just ext3; and so on...) and the maturity of the softwares involved (linux kernel, ext3fs, postfix) I'd think there should be a more or less agreed on set of best practices to filesystem related tuning. I'm trying to get a roundup of them: data=journal became the default in recent kernels (somewhere around 2.6.30 IIRC) so we should be ok with that Wietse Venema says atime must be on, but Postfix documentation recommendsnoatime while talking about the Incoming Queue. Does that mean that postfix needs atime on just for some queue directories and will benefit from noatime on the others? can we use noatime if we just don't use ETRN? filesystem can be mounted nodev,noexec,nosuid - no* won't prevent you from setting attributes (postfix uses exec attr) they just won't have any effect (we don't run anything from the spool) the fsync() issue cited by Wietse and/or the chattr -S are probably linked to sync/async options of ext3fs but I do not understand them enough. Mouting the filesystem with async option is equivalent to chattr -R -S the whole fs? Seems like it will increase performance, but will that pose a risk of "loss of mail after a system crash" or is it really "safe on /var/spool/postfix" ? would you tune anything else on postfix-2.6.x to work better on ext3 or do you leave defaults everywhere? is there a "best" linux I/O scheduler for this kind of workload (namely CFQ or deadline?) or that's something that will vary too much based on hardware configuration? would you tune anything else in the filesystem or in the kernel? anything else?

• System freezes during boot process

  - by slugster

  Hi everyone, i have a machine running Win7 Ultimate. It was running fine, then it just froze - all the stuff i was doing was still on the screen, but mouse and keyboard input was ignored, any animation that was happening on the screen stopped, the machine literally just froze. So i rebooted (power off button), from then on the machine will reboot, but it ultimately freezes again. The instance when this happens will vary - i have made it as far as the Windows login screen, but mostly it will do the POST, then give me the option to press F1 to continue or Del to enter BIOS settings (but of course pressing a key has no effect - it's frozen!). I have disconnected everything not necessary for the boot process, the only peripheral that remains attached is the keyboard. (even the network cable is disconnected). Prior to this the machine was operating fine. The install of Win7 is only 2 days old, and it was a fresh reinstall (i.e. not an upgrade or repair). Can anyone give me an indication of what may be wrong here? I'm not sure if this question should be here or on SuperUser, please migrate it if i have chosen the wrong board.

• Can I use IIS to do ActiveDirectory single-sign-on for another website?

  - by brofield

  I'm trying to add Active Directory single-sign-on support to an existing SOAP server. The server can be configured to accept a trusted reverse-proxy and use the X-Remote-User HTTP header for the authenticated user. I want to configure IIS to be the trusted proxy for this service, so that it handles all of the Active Directory authentication for the SOAP server. Basically IIS would have to accept HTTP connections on port X and URL Y, do all the authentication, and then proxy the connection to a different server (most likely the same X and Y). Unfortunately, I have no knowledge of IIS or AD (so I am trying my best to learn enough to build this solution) so please be gentle. I would assume that this is not an uncommon scenario, so is there some easy way to do this? Is this sort of functionality built into IIS or do I need to build some sort of IIS proxy program myself? Is there a better option for getting the authentication done and the X-Remote-User HTTP header set than requiring IIS? Update: For example, what I am trying to create is: [CLIENT] [IIS] [AD] [SOAP-SERVER] 1. |---------------->| 2. |<--------------->|<---------->| 3. |--------------------------->| 4. |<---------------------------| 5. |<----------------| 1. POST to http://example.com/foo/bar.cgi 2. Client is not authenticated, so do authentication 3. Once validated, send request to server (X-Remote-User: {userid}) 4. Process request, send response 5. Forward response to client I need to know how to configure IIS to do the automatic authentication of the user using AD, and then to proxy the request to the actual server, sending the userid in the X-Remote-User HTTP header.
