• recommendations for efficient offsite remote backup solution of vm's

  - by senorsmile

  I am looking for recommendations for backing up my current 6 vm's(and soon to grow to up to 20). Currently I am running a two node proxmox cluster(which is a debian base using kvm for virtualization with a custom web front end to administer). I have two nearly identical boxes with amd phenom II x4's and asus motherboards. Each has 4 500 GB sata2 hdd's, 1 for the os and other data for the proxmox install, and 3 using mdadm+drbd+lvm to share the 1.5 TB's of storage between the two machines. I mount lvm images to kvm for all of the virtual machines. I currently have the ability to do live transfer from one machine to the other, typically within seconds(it takes about 2 minutes on the largest vm running win2008 with m$ sql server). I am using proxmox's built-in vzdump utility to take snapshots of the vm's and store those on an external harddrive on the network. I then have jungledisk service (using rackspace) to sync the vzdump folder for remote offsite backup. This is all fine and dandy, but it's not very scalable. For one, the backups themselves can take up to a few hours every night. With jungledisk's block level incremental transfers, the sync only transfers a small portion of the data offsite, but that still takes at least a half an hour. The much better solution would of course be something that allows me to instantly take the difference of two time points (say what was written from 6am to 7am), zip it, then send that difference file to the backup server which would instantly transfer to the remote storage on rackspace. I have looked a little into zfs and it's ability to do send/receive. That coupled with a pipe of the data in bzip or something would seem perfect. However, it seems that implementing a nexenta server with zfs would essentially require at least one or two more dedicated storage servers to serve iSCSI block volumes (via zvol's???) to the proxmox servers. I would prefer to keep the setup as minimal as possible (i.e. NOT having separate storage servers) if at all possible. I have also briefly read about zumastor. It looks like it could also do what I want, but it appears to have halted development in 2008. So, zfs, zumastor or other?

• File/folder permissions and groups on Linux with Apache

  - by phobia

  I'm trying to learn about permissions on linux webserver with apache. Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant. What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host". My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either. To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world, so a 701 basically works, but won't let some users in. So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group? I was aiming at having 4 groups: 1. webapp same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo. 2. dev_int can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root 3. dev_ext can read write and execute in all client folders, but cannot access anything outside of the webapp root 4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders An example of folder structure: webroot    no users in the aforementioned groups can go outside of here some_project    :dev_int only webapp live    :webapp only staging    :dev_int and :dev_ext clients    :dev_int and :dev_ext client_1    :dev_int, :dev_ext and client1:clients public_html dev developer_1    developer_1:dev_int OR :dev_ext public_html

• How to bind old user's SID to new user to remain NTFS file ownership and permissions after freshly reinstall of Windows?

  - by LiuYan ??

  Each time we reinstalled Windows, it will create a new SID for user even the username is as same as before. // example (not real SID format, just show the problem) user SID -------------------- liuyan S-old-501 // old SID before reinstall liuyan S-new-501 // new SID after reinstall The annoying problem after reinstall is NTFS file owership and permissions on hard drive disk are still associated with old user's SID. I want to keep the ownership and permission setting of NTFS files, then want to let the new user take the old user's SID, so that I can access files as before without permission problem. The cacls command line tool can't be used in such situation, because the file does belongs to new user, so it will failed with Access is denied error. and it can't change ownership. Even if I can change the owership via SubInACL tool, cacls can't remove the old user's permission because the old user does not exist on new installation, and can't copy the old user's permission to new user. So, can we simply bind old user's SID to new user on the freshly installed Windows ? Sample test batch @echo off REM Additional tools used in this script REM PsGetSid http://technet.microsoft.com/en-us/sysinternals/bb897417 REM SubInACL http://www.microsoft.com/en-us/download/details.aspx?id=23510 REM REM make sure these tools are added into PATH set account=MyUserAccount set password=long-password set dir=test set file=test.txt echo Creating user [%account%] with password [%password%]... pause net user %account% %password% /add psgetsid %account% echo Done ! echo Making directory [%dir%] ... pause mkdir %dir% dir %dir%* /q echo Done ! echo Changing permissions of directory [%dir%]: only [%account%] and [%UserDomain%\%UserName%] has full access permission... pause cacls %dir% /G %account%:F cacls %dir% /E /G %UserDomain%\%UserName%:F dir %dir%* /q cacls %dir% echo Done ! echo Changing ownership of directory [%dir%] to [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q echo Done ! echo RunAs [%account%] user to write a file [%file%] in directory [%dir%]... pause runas /noprofile /env /user:%account% "cmd /k echo some text %DATE% %TIME% > %dir%\%file%" dir %dir% /q echo Done ! echo Deleting and Recreating user [%account%] (reinstall simulation) ... pause net user %account% /delete net user %account% %password% /add psgetsid %account% echo Done ! %account% is recreated, it has a new SID now echo Now, use this "same" account [%account%] to access [%dir%], it will failed with "Access is denied" pause runas /noprofile /env /user:%account% "cmd /k cacls %dir%" REM runas /noprofile /env /user:%account% "cmd /k type %dir%\%file%" echo Done ! echo Changing ownership of directory [%dir%] to NEW [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q cacls %dir% echo Done !

• Cannot access website from inside network

  - by musclez

  I have a website running from my internal network available at the example IP 192.168.1.5. When I type this in to the browser, it redirects to my domain name ie, "example.com", and gives me Error code: ERR_CONNECTION_REFUSED. Any other machine that is inside of the network can access the website. The website is also accessible outside of the network. Other services from the server, like file sharing or ftp, are available to all machines in the network including the one i'm having issues http issues with. The issue may be linked to a proxy service, but from my understanding the service has been completely disabled and any executable have been uninstalled from the machine. I am wondering if there is some residual proxy information remaining on the machine that limits the connection. I'm fairly positive that "example.com" is what is being blocked by the local machine, and not an IP address being blocked or a faulty connection. When I examine the hosts file, there are no redirects to the local machine for "example.com". There was a rule, as on my other machines within the network: 192.168.1.5 example.com But i have since removed that for troubleshooting purposes. What intrigued me is that when I use the actual IP, the IP address will redirect to the domain in the browser and THEN say ERR_CONNECTION_REFUSED. Server-Side Results The server logs are reporting this: example.com ::1 - - [Date & time] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2. 2.22 (Unix) (internal dummy connection)" However, this seems to be irrelevant as it is not triggered when I try to connect to the server with the specified machine. Fiddler results: Host: *example.com* Proxy-Connection: keep-alive Chrome-Side [Fiddler] The connection to 'example.com' failed. Error: ConnectionRefused (0x274d). System.Net.Sockets. SocketException No connection could be made because the target machine actively refused it 01.23.45.67:80 01.23.45.67:80 would be the external IP, which the server and the machine in question both share. I am doing so reading into 0x274d and its coming back with .NET web.config information. I am still at a loss to what to do with this information. I have WireShark running as well. Theres is a lot of sensitive information in the readout and I'm not sure what to extract from it. Either way, if it helps, I can access that information if anyone would like me to. Thanks for the help!

• How to configure Transparent IP Address Sharing (TAS) on a Mediatrix 4102 with DGW 2.0 firmware?

  - by Pascal Bourque

  I am making the switch to VoIP. I chose voip.ms as my service provider and Mediatrix 4102 as my ATA. One reason why I chose the Mediatrix over other popular consumer ATAs is that it's supposed to be easy to place it in front of the router, so it can give priority to its own upstream traffic over the home network's upstream traffic. This is supposed to work transparently, with the ATA and router sharing the same public IP address (the one obtained from the modem). They call this feaure Transparent IP Address Sharing, or TAS. Their promotional brochure describes it like this: The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. I am interested by this feature because my router, an Apple Time Capsule, doesn't support QoS and cannot give priority to the voice packets if the ATA is behind the router. However, after hours of searching the web, reading the documentation, and good ol' trial and error, I haven't been able to configure the Mediatrix to run in this mode. Then I found a version of the manual that looks like it was for a previous version of the firmware (SIP), where there is an entire section dedicated to configuring TAS (starting at page 209). But my Mediatrix comes with the DGW 2.0 firmware, whose documentation does not mention TAS at all. So I tried to follow the TAS setup instructions from the SIP documentation and apply them to my DGW firmware, using the Variable Mapping Between SIP v5.0 and DGW v2.0 document as a reference, but no success. Some required SIP variables don't have an equivalent in DGW. So it looks like the DGW firmware does not support TAS at all, or if it does they are not doing anything to help us set it up. So right now, the Mediatrix is behind the router and VoIP works perfectly except when my upstream bandwidth is saturated. My questions are: Is downgrading to SIP firmware the only way to have my Mediatrix 4102 run in TAS mode? If not, anybody knows how to setup TAS on the DGW firmware? Is TAS mode the only way to give priority to the voice packets if I want to keep my current router (Apple Time Capsule)? Thanks!

• Planning trunk capacity for multiple GbE switches

  - by wuckachucka

  Without measuring throughput (it's at the top of the list; this is just theoretical), I want to know the most standard method for trunking VLANs on multiple Gigabit (GbE) switches to a core Layer 3 GbE switch. Say you have three VLANs: VLAN10 (10.0.0.0/24) Servers: your typical Windows DC/file server, Exchange, and an Accounting/SQL server. VLAN20: (10.0.1.0/24) Sales: needs access to everything on VLAN10; doesn't need access to VLAN30 and vice-versa. VLAN20: (10.0.1.0/24) Support: needs access to everything on VLAN10; doesn't need access to VLAN20 and vice-versa. Here's how I think this should work in my head: Switch #1: Ports 2-20 are assigned to VLAN20; all the Sales workstations and printers are connected here. Optional 10GbE combo port #1 is trunked to L3 switch's 10 GbE combo port #1. Switch #2: Ports 2-20 are assigned to VLAN30; all the Support workstations and printers are connected here. Optional 10GbE combo port #1 is trunked to L3 switch's 10 GbE combo port #2. Core L3 switch: Ports 2-10 are assigned to VLAN10; all three servers are connected here. With a standard 10/100 x 24 switch, it'll usually come with one or two 1 GbE uplink ports; carrying over this logic to a 10/100/1000 x 24, the "optional" 10 GbE combo ports that most higher-end switches can get shouldn't really be an option. Keep in mind I haven't tested anything yet, I'm primarily moving in this direction for growth (don't want to buy 10/100 switches and have to replace those within a couple of years) and security (being able to control access between VLANs with L3 routing/packet filtering ACLs). Does this sound right? Do I really need the 10 GbE ports? It seems very non-standard and expensive, but it "feels" right when you think about 40 or 50 workstations trunking up to the L3 switch over 1 GbE standard ports. If say 20 workstations want to download a 10 GB image from the servers concurrently, wouldn't the trunk be the bottleneck? At least if the trunk was 10 GbE, you'd have 10x1GbE nodes being able to reach their theoretical max. What about switch stacking? Some of the D-Links I've been looking at have HDMI interfaces for stacking. As far as I know, stacking two switches creates one logical switch, but is this just for management I/O or does the switches use the (assuming it's HDMI 1.3) 10.2 Gbps for carrying data back and forth?

• nginx probably deliering wrong filetype for .css file with php tags

  - by Katai

  And again - NGINX is giving me many Questions today :) Like always, I already tried around for a while, but cant seem to fix this issue: I just configured NGINX to handle my .css files equal to my .php files (to parse PHP tags inside the CSS file). This works perfectly, and the file is found and delivered. I could debug it with FIrebug, and everything is OK (it displays the contents of the .css inside the opened <link> tag). So, everything working, right? Wrong. It has the CSS, but it does not interpret it! What I mean by this: apparently, the file-type of the CSS (or aplication-type, whatever) is wrong. The Page can access the CSS, but doesnt bother at all to actually use it. What I checked / tried: There are no PHP errors inside of the .css, so that one is out The .css is accessible. I can call the URI manually, or check if the included URL finds it: both works The .css has no syntax errors (i switched to a css that just has body {background-color: #000; } It works whitout NGINX I deleted the browser cache / restarted NGINX after config rewrites Here the configuration: server { listen 80; server_name localhost; access_log /var/log/nginx/board.access_log; error_log /var/log/nginx/board.error_log warn; root /var/www/board/public; index index.php; fastcgi_index index.php; location / { try_files $uri $uri /index.php; } location ~ (\.php|\.css)$ { try_files $uri =404; include /etc/nginx/fastcgi_params; #keepalive_timeout 0; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass 127.0.0.1:7777; } } Firebug 'Network' Response Header: Connection keep-alive Content-Encoding gzip Content-Type text/html Date Sat, 16 Jun 2012 10:08:40 GMT Server nginx/1.0.5 Transfer-Encoding chunked X-Powered-By PHP/5.3.6-13ubuntu3.7 I think I just answered my own question. Is the Content-Type text/html the problem? How can I remove that? My personal guess is that I have to use this in some way include /etc/nginx/mime.types; default_type application/octet-stream; But I'm not sure... anyone an idea how to solve this? TLDR; CSS file is delivered correctly, but it doesnt seem to be 'used' as CSS from the browser. (Tested, works on apache)

• Wake On Lan only works on first boot, not sequent ones

  - by sp3ctum

  I have converted my old Dell Latitude D410 laptop to a server for tinkering. It is running an updated Debian Squeeze (6) with a Xen enabled kernel (I want to toy with virtual machines later on). I am running it 'headless' via an ethernet connection. I am struggling to enable Wake On Lan for the box. I have enabled the setting in the BIOS, and it works nicely, but only for the first time after the power cord is plugged in. Here is my test: Plug in power cord, don't boot yet Send magic Wake On Lan packet from test machine (Ubuntu) using the wakeonlan program Server expected to start (does every time) Once server has booted, log in via ssh and shut it down via the operating system After shutdown, wake server up via WOL again (fails every time) Some observations: Right after step 1 I can see the integrated NIC has a light on. I deduce this means the NIC gets adequate power and that the ethernet cable is connected to my switch. This light is not on after step 4 (the shutdown stage). The light becomes back on after I disconnect and reconnect the power cord, after which WOL works as well. After step 4 I can verify that wake on lan is enabled via the ethtool program (repeatable each time) This blog post suggested the problem may lay in the fact the motherboard might not be giving adequate power to the NIC after shutdown, so I copied an acpitool script that supposedly should signal the system to give the needed power to the card when shut down. Obviously it did not fix my issue. I have included the relevant power settings in the paste below. I have tried different combinations of parameters of shutdown (the program) options, as well as the poweroff program. I even tried "telinit 0", which I figured would do the most direct boot via software. If I keep the laptop's power button pressed down and do a hard boot this way, the light on the ethernet port stays lit and a WOL is possible. I copied a bunch of hopefully useful information in this paste I have tried this with the laptop battery connected and without it. I get the same result. Promptly pressing the power button causes the system to shut down with the message "The system is going down for system halt NOW!", and WOL is still unsuccessful.

• APC ups es 700 randomly overload

  - by Matteo Mosca

  First of all, I live in Italy, Europe, so keep this in mind for Volt/Watt considerations. Standard voltage in Italian apartments is 220V. In my living room I have 2 APC ups, one being an ES-550 and the other an ES-700 They each have 4 slots for surge protection only, and 4 slots for surge protection + battery backup. Just to give all the information, they both got their battery replaced less than one month ago. The ES-550 works fine, without any problem. On the battery I have connected: Pc Monitor Sony Bravia 46'' 4th slot is empty The ES-700 has the following on battery: Xbox 360 Ps3 (standby when not used) Wii (standby when not used) Netgear 8 port switch (always on) Here's what happens: the ES-700, randomly, but mostly at night when I'm sleeping, goes like "overload", with the constant beep. If I try to shut it off keeping the power button pressed, nothing happens. The only thing that works is unplugging random stuff (sometimes unplugging 1 console works, other times I have to unplug all 4 devices). Every time this happens the problem is "real", meaning the 4 devices become unpowered, so it's not just an "alarm no working properly" problem. While I'm sleeping, of course, the power usage is what described on the list, 2 devices on standy, 1 off and 1 on. Today it happened again while I was playing with my Ps3. I unplugged it, problem went away. I plugged it again, and it kept working fine. I just can't figure out what's the problem. The only additional info I can provide is that this behaviour started after a big power outage last december 26 (a blackout that lasted almost all day) but the "surge protection" part of those UPS should be there for those problems, to leverage peaks when power goes away or gets restored. Another funny thing is, althought it might not be related, for a couple of days after that event the Wii was unable to power on, I thought its power transformer was broken, but then it suddenly started working again. I can be sure it's not the Wii overloading the UPS because the overload happens even if I leave the Wii unplugged. Any suggestion is really appreciated, and I can provide any additional info, if needed, that didn't come to mind right now. Thanks.

• Problems migrating an EBS backed instance over AWS Regions

  - by gshankar

  Note: I asked this question on the EC2 forums too but haven't received any love there. Hopefully the ServerFault community will be more awesome. The new AWS Sydney region opening up is something that we've been waiting for for a long time but I'm having a lot of trouble migrating our instances over from N. California. I managed to migrate 1 instance over using CloudyScripts to move a snapshot and then firing up a new instance in the Sydney region. This was a very new instance so both the source and destination were running on a Ubuntu 12.04 LTS server and I had no issues there. However, the rest of our instances are all Ubuntu 10.04 LTS and with these, I'm having a lot of problems. I've tried following: 1- following the AWS whitepaper on moving instances which was given to us at the recent Customer Appreciation Day in Sydney where the new region was launched. The problem with this approach was with the last step (Step 19) here you register the image: ec2-register -s snap-0f62ec3f -n "Wombat" -d "migrated Wombat" --region ap-southeast-2 -a x86_64 --kernel aki-937e2ed6 --block-device-mapping "/dev/sdk=ephemeral0" I keep getting this error: Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' does not exist which I think is due to the kernel_id not existing in the Sydney region? 2- Using CloudyScripts to move a snapshot and then creating a new volume and attaching to a new instance in Sydney This results in the instance just hanging on boot and failing the status checks. I can't SSH in or look at the server log I suspect that my issue is with finding the right kernel_id for the volume in the new region. However I can't seem to work out how to go about finding this kernel_id, the ones I've tried (from the original instance) don't result in the Client.InvalidAMIID.NotFound: The AMI ID 'ami-937e2ed6' error and any other kernel_id just won't boot. I've tried both 12.04 and 10.04 versions of Ubuntu. Nothing seems to work, I've been banging my head against a wall for a while now, please help! New (broken) instance i-a1acda9b ami-9b8611a1 aki-31990e0b Source instance i-08a6664e ami-b37e2ef6 aki-937e2ed6 p.s. I also tried following this guide on updating my Ubuntu LTS version to 12.04 before doing the migration but it didn't seem to work either, still getting stuck on updating the kernel_id http://ubuntu-smoser.blogspot.com.au/2010/04/upgrading-ebs-instance.html

• Compiling PHP with GD crashes with EXC_BREAKPOINT (SIGTRAP) on PPC Mac

  - by Ömer

  First of all, I should say that I have searched the whole Internet for this problem but I couldn't find any solution yet. I have a Mac mini PowerPC (PPC) and I run Apache webserver (httpd-2.2.22) with PHP (5.4.0) and I do all the configure & compilation jobs by myself. If configure with: './configure' '--prefix=/usr/local/php5' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc' '--with-config-file-path=/etc' '--with-zlib' '--with-zlib-dir=/usr' '--with-openssl=/usr' '--without-iconv' '--enable-exif' '--enable-ftp' '--enable-mbstring' '--enable-mbregex' '--enable-sockets' '--with-mysql=/usr/local/mysql' '--with-pdo-mysql=/usr/local/mysql' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mcrypt' then the PHP works flawlessly. But if I add the GD module by adding these to the script above: '--with-gd' '--with-jpeg-dir=/usr/local/lib' '--with-freetype-dir=/usr/X11R6' '--with-png-dir=/usr/X11R6' '--with-xpm-dir=/usr/X11R6' the PHP gets configured and compiled without any errors but it causes EXC_BREAKPOINT (SIGTRAP) (see the Crash Reporter log below) when I request a page which calls PHP module. It's obvious that something related to the GD module is causing this, probably FreeType module because it's present in the log but it may not be definite of course.

• How could I let Skydrive desktop sync to MicroSD in Windows 8 tablet?

  - by peSHIr

  I have a Samsung Slate 7 tablet with (now) Windows 8 on it. This machine has a 64 Gb SSD and I have a 64 Gb MicroSD card in it. I also have a Skydrive on my main Microsoft ID that contains about 45 Gb of content. With Windows and some development stuff installed, my Skydrive will not fit on the main drive of the tablet. (Besides, my idea was to keep data on the memory card anyway, to make it easier to repave the machine without data loss if need be.) My problem should now be clear: I want to install the Skydrive desktop app to sync my Skydrive to the MicroSD card. This is not possible, as Skydrive does not allow syncing files to removable drives. I have tried a number of things already, but none of them worked: Use the mklink command line tool to create a directory link/junction from a folder name on SSD to a folder on the MicroSD and then try to install Skydrive sync to the SSD link folder. Skydrive however still recognizes this as something it does not want to sync onto. The various different filter drivers mentioned on Agnipulse (including the Hitachi one) that should make windows see some or all of the removable drives in the system as fixed drives do not seem work on (64-bit) Windows 8: they either can't be installed, do nothing and/or cause Windows 8 to go into Automatic Repair mode when rebooting. The Lexar BootIt app seems to be meant to flip the relevant bit in the on-board drive controller of supported USB pen drives, but I tried it anyway. Of course it did nothing to how the MicroSD card was seen. I have now run out of ideas, it seems, and I was wondering if anyone here has a solution to let Windows 8 see the MicroSD memory card in my tablet as a fixed drive instead of removable drive, or some other way of getting the Skydrive desktop to sync my Skydrive data to that MicroSD card. And to be complete: this is not a duplicate question of this or this as those ask about getting USB drives multiple partitions to work on Windows XP. This question is specific about getting desktop Skydrive to sync to MicroSD card in Windows 8, which seems to be a question I have not seen on superuser so far.

• Establishing a web page bookmarking process - looking for ideas to improve

  - by Matt

  Like many others, I have a process for bookmarking web pages to read later. My requirements for web page bookmarking are: Ability to bookmark pages must be available from all (within reason) platforms - PC/browser, mobile device, etc. Bookmarks must be centrally stored (implicit from #2) so that I can read the bookmarks from anywhere/any device Full text of web pages must be stored Bonus features would be: Bookmarks and page content should be full text searchable Maintain an archive indefinitely Distinguish between what's read vs. unread Bookmarked page content is cleaned up, e.g. ads eliminated, unnecessary html removed, pages better formatted for reading My current process (which addresses most of these requirements) is as follows: I set up a Gmail account with 2 labels, "Bookmarks Unread" and "Bookmarks Read" Gmail filters set up such that depending on the form of the address (using Gmail's '+string' functionality in addresses), the incoming bookmark gets labeled appropriately On each of my browsers/devices, I have an address book entry for [email protected] and [email protected]. If I want to clean up the page content, I use the Readability bookmarklet which does a great job of giving me the essential content only Anywhere I have Firefox, I use the Send Page by Email extension which, with 2 clicks, allows me to send the cleaned-up Readability page URL and content to one of the above email addresses. Where I don't have Firefox (e.g. iPhone or other mobile device) I use the native ability to send the current link via email (most/all apps have them, including the browser, RSS readers, NYTimes, etc.). In most cases (unless it's built into the particular app), this won't include the page body. The process is almost perfect. I've got the central access and ubiquitous access of Gmail as the storage mechanism, full text searchability (due to Gmail, but of course only for the URLs I send from that Firefox extension), a cleaned up page due to Readability, ability to read offline (assuming I use an IMAP client against Gmail) and permanent archiving of content, including what's been read vs. unread. The missing pieces are: The Send Page by Email Firefox extension seems to only send X bytes of a web page. Or some portion. So it limits my full text searchability. Where I don't have Firefox, I can only send the link, so no full text search at all in those cases. Instapaper looks like it meets most of my requirements (and bonus items). The only downside to me (personal preference) is that central storage is based on Instapaper vs. something more broad like Gmail, which as a generalized service and with Google behind it pretty much means it's permanent. I'm not too hung up on this, but I would definitely prefer to keep Gmail if possible. An upside of Instapaper is that it does the page clean-up as well as stores the entire page content, unlike my Firefox extension. Thoughts on addressing the gaps and improving this process further?

• Exchange 2010 forwarded emails by external servers being blocked

  - by MadBoy

  Our users were getting spam messages from their own accounts (same domain/login for example [email protected] to [email protected]). This is preety standard trick and I decided to block it so that anonymous users can't send emails as @company.com. This brought some problems on us like our printers not being able to send emails etc but I solved it with secondary smtp receiver on different port with ip restrictions. However it seems to affect forwarding by some e-mail servers as well: Hi. This is the qmail-send program at home.pl. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. : 89.14.1.26 failed after I sent the message. Remote host said: 550 5.7.1 Client does not have permissions to send as this sender --- Below this line is a copy of the message. Return-Path: Return-Path: Received: from mail.company.com [89.14.1.26] (HELO mail.company.com) by company.ho.pl [79.93.31.43] with SMTP (IdeaSmtpServer v0.70) id 488fcb01c2f069d9; Tue, 3 Jan 2012 09:46:55 +0100 Received: from EXCHANGE1.COMPANY ([fe80::d425:135f:b655:1223]) by EXCHANGE2.COMPANY ([fe80::193f:51ac:9316:cb27%14]) with mapi id 14.01.0355.002; Tue, 3 Jan 2012 09:46:55 +0100 From: =?iso-8859-2?Q?MadBoy?= So basically server forwards it without affecting email address it was send with and our servers treat it like spam. I used this command to block things: Get-ReceiveConnector "DEFAULT Exchange2" | Get-ADPermission -user "NT AUTHORITY\Anonymous Logon" | where {$_.ExtendedRights -like "ms-exch-smtp-accept-authoritative-domain-sender"} | Remove-ADPermission Is there anyway I can keep on receiveing things like forwards but be able to block things (except some dedicated antispam solution - this will be added later). Also how do I "reassing" back the permissions that was removed? EDIT to clarify: I have a domain domain.com configured as Authorative. Couple of our users are on project for differentcompany.com which is not on our servers or anywhere close. Now when they send an email from their accounts lets say [email protected] to [email protected] that special alias is configured so that any email it receives it forwards to multiple people including a group alias at our domain [email protected] and that group alias puts the email in users mailboxes. After the email is forwarded by [email protected] and it reaches our server it is denied because the forwarding done by the "external" server doesn't affect user information so for the server it seems like the [email protected] was actually sender and it treats it as spam and denies it. The server at differentcompany.com just adds itself to the header that it passed thru it and doesn't modify sender at anyway (seems like this is how forwarding works). Although I could probably allow this particular server as allowed to relay but this would seem to affect more servers/users as anyone can setup forwarding on their email back to our domain...

• How to configure Transparent IP Address Sharing (TAS) on a Mediatrix 4102 with DGW 2.0 firmware?

  - by Pascal Bourque

  I am making the switch to VoIP. I chose voip.ms as my service provider and Mediatrix 4102 as my ATA. One reason why I chose the Mediatrix over other popular consumer ATAs is that it's supposed to be easy to place it in front of the router, so it can give priority to its own upstream traffic over the home network's upstream traffic. This is supposed to work transparently, with the ATA and router sharing the same public IP address (the one obtained from the modem). They call this feaure Transparent IP Address Sharing, or TAS. Their promotional brochure describes it like this: The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. I am interested by this feature because my router, an Apple Time Capsule, doesn't support QoS and cannot give priority to the voice packets if the ATA is behind the router. However, after hours of searching the web, reading the documentation, and good ol' trial and error, I haven't been able to configure the Mediatrix to run in this mode. Then I found a version of the manual that looks like it was for a previous version of the firmware (SIP), where there is an entire section dedicated to configuring TAS (starting at page 209). But my Mediatrix comes with the DGW 2.0 firmware, whose documentation does not mention TAS at all. So I tried to follow the TAS setup instructions from the SIP documentation and apply them to my DGW firmware, using the Variable Mapping Between SIP v5.0 and DGW v2.0 document as a reference, but no success. Some required SIP variables don't have an equivalent in DGW. So it looks like the DGW firmware does not support TAS at all, or if it does they are not doing anything to help us set it up. So right now, the Mediatrix is behind the router and VoIP works perfectly except when my upstream bandwidth is saturated. My questions are: Is downgrading to SIP firmware the only way to have my Mediatrix 4102 run in TAS mode? If not, anybody knows how to setup TAS on the DGW firmware? Is TAS mode the only way to give priority to the voice packets if I want to keep my current router (Apple Time Capsule)? Thanks!

• ISC DHCP - Force clients to get a new IP address, instead of the being re-issued their previous lease's IP

  - by kce

  We are in the middle of a migration of our DHCP and DNS services from a Debian-based server to a Windows Server 2008 R2 implementation. The Debian server is running isc-dhcpd-V3.1.1. All of workstations are configured to have fixed-addresses between .3 and .40 (the motivation behind that choice is mostly management/political much like here). DHCP leases are given out in the range of .100 to .175. Statically configured servers live in the .200 block and above (which is mostly empty). When we move to the Windows platform, management/political considerations require me to move the IP ranges around again. We would like to keep .1 - .10 reserved for network appliances, switches, and other infrastructure. .200 will remain designated for servers. The addressing space in between should be available to clients and IPs should be dynamically allocated (Edit: instead of automatic as originally mentioned) by the server. My Address Pool on the Windows Server looks like this: 192.168.0.1 192.168.0.254 (Address range for distribution) 192.168.0.1 192.168.0.10 (IP addresses excluded from distribution) 192.168.0.200 192.168.0.254 (IP addresses excluded from distribution) Currently, we have all of our clients still on the .3 - .40 range, and a few machines still active in the .100 - .175 (although there are lots devices that are powered off that still have expired leases with IPs from that range). Since the lease "database" isn't shared between the old and new DHCP server how can I prevent clients from receiving a lease with an IP address that is currently being held by client with a non-expired lease from the old DHCP server? If I just expand the range on the Debian DHCP server to be 192.168.0.10 - 192.168.0.199 is there a way to force clients to not re-use their old IP address when they send their DHCPDISCOVER? Can I make the Windows DHCP server be authoritiative like the ISC implementation? The dhcpd.conf from the Debian server: ddns-update-style none; authoritative; default-lease-time 43200; #12 hours max-lease-time 86400; #24 hours subnet 192.168.0.0 netmask 255.255.255.0 { option routers 192.168.0.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; range 192.168.0.100 192.168.0.175; } host workstation-1 { hardware ethernet 00:11:22:33:44:55; fixed-address 192.168.0.3; } ... and so on until 192.168.0.40

• Best RAID setup for multimedia fileserver?

  - by Mr. Schwabe

  I'm building a fileserver for my small office. We do film and multimedia design. Only 3 clients connected. The server is primarily for local access to graphic assets and video files. I'm looking for advice on hardware and software required. Particularly for the RAID. I have the following objectives: A) merged capacity I'd like all other systems to access the data as a single mapped network drive that has an initial capacity of 10 TB. So perhaps 5x 2TB drives (plus mirror drives for redundancy). B) easy way to increase capacity Thinking long term, I'd like to 'easily' add more drives to the array for a potential two or three fold increase in capacity. So theoretically it could get upto a 30 TB raid array consisting of maybe 15x 2 TB drives of capacity (plus mirror drives for redundancy). C) maximum fault tolerance I want at least 1 mirror drive per capacity drive (in laymen's terms). So if I start with 10 TB / 5x 2TB of capacity, I suppose I would need another another 5x 2TB drives to be mirrors. So 10 drives total. But I'd also like potential for even more redundancy; with upto 2 additional mirrors per 'capacity drive' (and to be able to add them to the array anytime with ease). D) easy way to monitor drive health I'd like an intuitive interface for managing the raid and monitoring drive health The other systems accessing this network drive will be running Windows, but also the odd Ubuntu and MacOS system as well. Are these objectives attainable? What type of RAID setup do you recommend? What hardware will be required? Also what OS do you think this system should be running? Does it really matter? I'm no network admin - just a long time Windoze user, without much Linux experience. That said, I'm not opposed to a Linux solution if it's easy enough and more practical than a Windows OS for this server. Or maybe something such as Openfiler. Budget should hit the sweet spot for value and performance (hence my preference to use 2TB drives). The biggest focus is storage; aside from that the system just needs to keep the drives running optimally with perhaps 2 or 3 clients accessing / writing files at any given time. The hardware quote would start with something like 10x 2TB WD Caviar Blacks; about $1900 for the storage + $x for remaining parts. http://ncix.com/products/index.php?sku=42775&vpn=WD2001FASS&manufacture=Western%20Digital%20WD Your advice is appreciated, thanks!

• Hanging page loads every n loads - SOLVED

  - by Christian

  Hi Guys I recently moved my site to a new server (Apache 2, PHP5, MySQL5). The site is an Invision based forum. Every few posts / topics it just hangs. The data has been written because if you stop and reload, the post / thread is there. I thought it was a write issue initially, but nope. So, the data is written but the page load never completes. It doesn't leave the page where the data has been input. Whats the best way to trouble shoot this issue? The only thing I have done recently is reduce my MySQL timeouts, but I can't see that being an issue as the values are still big enough and there are no mentions of timeouts in the MySQL log. (For the record there is nothing in PHP's error log either) Thanks in advance! EDIT: I checked my server-status. It all looked ok, but I have a suspicion I was hitting my ServerLimit, so I doubled that. Also enabled my Keepalives. Will keep an eye on it. EDIT 2: Its now been a few days and this is still occuring. I have more info though; Apache is throwing seg faults, but enabling core dumps does not produce them. I have tried disabling the modules in apache but it just stops things from working. I fear it may actually be DNS related. If I watch Live Headers in Firefox, absolutely nothing happens during this 'hanging' period. After that, the responses come back fairly promptly. UPDATE (05/04): I built the latest versions of Apache and PHP from source, no luck. I then removed those and used the remi repo to update all my packages to the latest stable. Segfaults seem to have stopped, but the hanging is continuing. ini's are at; www.skylinesaustralia.com/php.ini www.skylinesaustralia.com/my.cnf www.skylinesaustralia.com/httpd.conf UPDATE - SOLVED! - The issue was having a gigantic query cache size in MySQL. It was 2GB, changing it to 64M sorted it. Thanks for all the help everybody, much appreciated!!

• Why my Buffalo router keeps on sending rdp, netbios, ftp, http requests?

  - by user192702

• DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

  - by stakx

  I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

• Changing Physical Path gives blank homepage

  - by Julie

  I have two websites ASP Classic - www.company.com and www.companytesting.com. At this time of year, company.com is pointed to a folder called website2012 and companytesting.com is pointing to a folder called website2013. The contents of those two folders are almost identical, just minor changes for our season change (which I was supposed to do today - lol). Up until a couple of weeks ago, I was running Windows Server 2003. To update the "live" website, I'd make a copy of the test site folder, and rename it website2013R1, and point the test site there, then point the live site at website2012. We now have Windows Server 2008 R2 64. (I had someone migrate the websites to the new server for me.) The companytesting.com site, when I pointed it to website2013R1, worked fine. The company.com site, when I pointed it to website2013 (which worked just before, for the companytesting.com site) gives an empty page. (i.e. view source = nothing there.) There is nothing in the failed request log when this happens. I can use the Explore button/link (upper right) in IIS7.5 and see all of the files there. If I use the browse button (either in general or on the index.asp page) I get the blank page again. One weirdness about how these are set up is that companytesting.com uses a login (which I think is windows authentication - it's simply a single username and password for staff, and to keep the GoogleBots out of it). Obviously, company.com does not. But redirecting the to website2013r1 kept the login in place. (So I'm not absolutely clear whether that's attached to the folder or to the site. Hitting the company.com site after changing the path did not yield a password request.) The permissions on the folders all seem to be the same, but obviously, I'm missing something. Why isn't changing the physical path working? As is probably obvious, I'm not knowledgeable about servers. I did OK in 2003, but since it's not my main task and I'm buried right now, I have barely looked at 2008. So I may have really stupid questions when you ask me to check something.

• A dusty server room

  - by pauska

  Here's the story.. The owners of the building we lease office space from decided to do a renovation of the exterior. This involved in some pretty heavy work at the level where our server room is, including exchanging windows wich are fit inside a concrete wall. My red alert went off when I heard that they were going to do the same thing with our server room (yes, our server room has a window. We're a small shop with 3 racks. The window is secured with steel bars.) I explicity told the contractor that they need to put up a temporarily wall between our racks and the original wall - and to make sure that the temporary wall is 100 % air and water-tight. They promised to do so. The temporary wall has a small door in it, so that workers can go in/out through the day (through our server room, wich was the only option....). On several occasions I could find the small door half-way shut while working evenings/nights. I locked the door, and thought that they would hopefully get the point soon and keep the door shut. I even gave a electrician a mouthful when I saw that he didn't close the door properly. By this point - I bet that most of you get a picture of what happened. Yes, they probably left the door open while drilling in the concrete. I present you our 4 weeks old EMC VNX: I'll even put in a little bonus, here is the APC UPS one rack further away from the temporary wall. See the nice little landing strip from my finger? What should I do? The only thing that comes to mind is to either call all our suppliers (EMC, HP, Dell, Cisco) and get them to send technicians to check out all the gear in the server room, or get some kind of certified 3rd-party consulant to check all of it. Would you run production systems on this gear? How long? Edit: I should also note that our aircondition isn't exactly enterprise-grade, given the nature of our small room. It's just a single inverter, wich have failed one time before I started working here (failed inverters usually leads to water dripping out).

• MBPro, mid 2010 can't see Dlink DIR655 signal after sleep etc

  - by user88114

  This is my son's MBP 7,1 running Snow Leopard 10.6.7. Router signal is fine since iPad, Wintel on same table 20 feet from router are fine. the MBP however frequently wakes and fails to find the internet. iStumbler can see 1 neighbours hub and my garden hub are there but can't get to the normal DIR655 wifi... no ping no en0 or en1 device seems to exist. Airport off and on does not help. He just resets router and it all works but this does not please me! I must admit the winter sometimes seems to loose connect too, but less so. The DIR655 (hardware rev A3) is on the original EU firmware 1.10, I'm cautious about jumping to latest 1.31EU since no downgrade seems to be possible and that feels a bit risky as so much is set up and working fine. If I use the DIR655 admin web and release the lease the MBP has then wake it all worked OK. So I suspect lease timing/locking issue but unsure how to check up, plus why iStumbler seems to say the network is not visible at all when I sit on the iPad right next to it just fine.. I do not think there are any channel overlaps and we also have RFquiet DECT phones (Orchid) that are silent until lifted or called. Anyway signals all show low interference and high throughput except for this failure to connect. Just walked the MBP to the garden office and iStumbler now sees the more distant DIR655 signal although it will not connect to it (does not show under Sys Prefs NetNetwork names) even after airport off & on... It also refuses to connect to my garden network (an old Belkin acting as AP wired to DIR655), the signal it can see and even net name in Sys Prefs NetNetwork names (2 mins later):NOW both names ARE visible, but both fail to accept the correct WPA2 password and keep asking again after failing to connect. IT ALL MAKES NO SENSE TO ME. Just revoked the lease for the MBP on DIR655 and no changes although this seemed to help MBP wake into connection 1 hour ago. OK a bit of walking about to report. Carried MBP across garden towards DIR655, a few other wifis show up on iStumbler, low signals all channel 1. Right next to DIR655 but iStumbler not showing it, although most other wifi's have gone. I'd say iStubler is suffering timeouts&hangs but hard to be sure. Lots of attempts to Airport on/off, join other etc and suddenly I get to connect, get given new IP (I revoked), can browse. Walk away, connection drops quite soon at 30 feet then reconnected briefly then died again. MUST ATTEND ELSEWHERE FOR A BIT...
