• Permission denied problem in Freenas + Transmission

  - by Torbjörn Karlsson

  Running Freenas 0.7.2 (5543) and Transmission 2.11 The problem it that i can not save a torrent where ever i want.. For example... I can save in: /nmt/1-500gb/Tv/dexter but i can not save in /nmt/4-1000gb/tv/Lost When i try to save in the lost folder I get a permission denied error in the Web interface. But when I try to save the same torrent file in the dexter folder everything works fine... This is probably an easy thing to fix, but I'm new to Freenas. The user name for Transmission is TorrentUser if that helps. Now I find out that I can not browse the disk in Quixplorer.. I can browse nmt/4-1000gb/ but not /nmt/1-500gb When I try to browse the nmt/4-1000gb/ I get Unable to read directory $ mount /dev/md0 on / (ufs, local) devfs on /dev (devfs, local) procfs on /proc (procfs, local) /dev/fuse1 on /mnt/5 - 500gb (fusefs, local, synchronous) /dev/fuse2 on /mnt/2 - 1000gb (fusefs, local, synchronous) /dev/fuse3 on /mnt/3 - 1000gb (fusefs, local, synchronous) /dev/fuse4 on /mnt/4 - 1000gb (fusefs, local, synchronous) /dev/fuse5 on /mnt/320GB - USB (fusefs, local, synchronous) /dev/md1 on /var (ufs, local) /dev/da0a on /cf (ufs, local, read-only) /dev/fuse0 on /mnt/1 - 500gb (fusefs, local, synchronous) Dont work : 1 - 500gb 2 - 1000gb 3 - 1000gb Works: 320GB - USB 4 - 1000gb 5 - 500gb And this 3 disk is the same disks that I can save my torrents to. Ps. Every disk works perfect when i use ftp...

• Scheduling Automatic Backups for Virtual Private Web Server running CENTOS 6.3 and WHM

  - by Oliver Farrell

  I'm pretty new to administering my own VPS - but thus far am finding it quite a compelling experience. There's something quite refreshing about having complete control over everything it does. One thing that I would like to look at is a suitable backup solution (a few times a day). My current setup is as follows: I'm running a CENTOS 6.3 VPS with a single 25GB hard drive solely for the purpose of hosting websites. I'm using WHM & cPanel for administering them. I now plan on adding an additional hard disk and hooking it up to my VPS. What I'm not sure about is how I get the two disks talking and get the backup process going. I'm not a seasons SSH-er so don't really know where to start. I'm hosting with Serverlove (one of the best hosting providers I've used) and am provided with a number of unique identifiers for each hard disk so I imagine these may play a part in linking them together. I appreciate that this is a little vague (I'm clutching at straws) but any assistance is very much appreciated.

• No sound through headset - only mic is working

  - by Kristis

  I noticed that no sound is being played to my headphones. The laptop has a conexant sound card together with the sounds apps provided. But the thing is that I also noticed that now instead of one playback device - 2 are presented: speakers and headphones. And while speakers do play sound nicely - even test sound are not played through headphone output. Also, headphone output does not have a jack assigned to it, while speakers have L R Rear panel Analog Jack(my laptop does not have a jack on the back - only on the right). Also - my headphones have a mic as well - and when I plug it in - the mic is working(using top panel digital jack),but the headphones themselves are not. And laptop is recognizing when audio device is plugged in. And I checked the headset on other devices - the headphones are working. I have tried updating drivers, rolling back drivers and completely uninstalling drivers and then restarting - nothing helped. I imagine that I somehow need to reconfigure the jack configuration just have no idea how and where. Any suggestions? Thanks

• Modifier key bug with Adobe Design Standard CS4 (Mac OS 10.6.6)

  - by Andy

  When I launch the Adobe apps, they ask me if I want to delete the preferences file. I say 'no'. Then, when using the apps, none of the tools seem to work properly, eg in Illustrator, I can't move objects without it duplicating the object. Photoshop constantly displays the contextual menu icon that usually only appears when you hold down the control key. I can't do any work in them when this happens, so I am forced to log out and then back in. They work for a while and then this annoying bug happens again. I think it must be to do with the modifier keys (command option and control). I think Adobe's apps must think I'm permanently pressing the modifier keys down - the thing is, no other app on my machine has this problem! Does anyone else experience this? Or have a fix for it? Any suggestions much appreciated. Running: Mac OS X 10.6.6 on an iMac. Adobe CS4 Design standard installed.

• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• Optimizing Disk I/O & RAID on Windows SQL Server 2005

  - by David

  I've been monitoring our SQL server for a while, and have noticed that I/O hits 100% every so often using Task Manager and Perfmon. I have normally been able to correlate this spike with SUSPENDED processes in SQL Server Management when I execute "exec sp_who2". The RAID controller is controlled by LSI MegaRAID Storage Manager. We have the following setup: System Drive (Windows) on RAID 1 with two 280GB drives SQL is on a RAID 10 (2 mirroed drives of 280GB in two different spans) This is a database that is hammered during the day, but is pretty inactive at night. The DB size is currently about 13GB, and is used by approximately 200 (and growing) users a day. I have a couple of ideas I'm toying around with: Checking for Indexes & reindexing some tables Adding an additional RAID 1 (with 2 new, smaller, HDs) and moving the SQL's Log Data File (LDF) onto the new RAID. For #2, my question is this: Would we really be increasing disk performance (IO) by moving data off of the RAID 10 onto a RAID 1? RAID 10 obviously has better performance than RAID 1. Furthermore, SQL must write to the transaction logs before writing to the database. But on the flip side, we'll be reducing both the size of the disks as well as the amount of data written to the RAID 10, which is where all of the "meat" is - thereby increasing that RAID's performance for read requests. Is there any way to find out what our current limiting factor is? (The drives vs. the RAID Controller)? If the limiting factor is the drives, then maybe adding the additional RAID 1 makes sense. But if the limiting factor is the Controller itself, then I think we're approaching this thing wrong. Finally, are we just wasting our time? Should we instead be focusing our efforts towards #1 (reindexing tables, reducing network latency where possible, etc...)?

• IIS7 Binary Stream Error

  - by WDuffy

  I'm struggling to understand the problem I'm seeing so please accept my apology if the question is vague. I'm running a classic asp app in IIS7 and everything seems to work fine except for one issue that has me stumped. Basically, files can be downloaded from the server which is done using the sendBinary method of Persits ASP Upload component. This component works fine for uploading etc it's just the downloading I have a problem. The strange thing is, I cannot have a pure asp page that serves the binary file. Everything works fine in II6, but in II7 there is a strange problem. For example this does not work. <% SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> However, if I put anything in front of the asp code the file is served fine. serve this <% SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> I can also write something to the response stream first and it works fine. <% Response.Write("server this") SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> Does anyone have any ideas of what could be causing this or has anyone ran into a similar situation? I'm sure it has something to do with the setup in IIS 7.

• Update BIOS on Sun Fire X4150 server

  - by Massimo

  I have some Sun Fire X4150 servers with a very old BIOS release (1ADQW015), which seems to have some compatibility problems with WMware ESX Server 3.5 and Windows 2008 R2 virtual machines; so I want to update the BIOS on them. The problem: according to this page, if your servers run ELOM (mine do), you first need to update to the latest ELOM release, then to the interim transition release, then finally you can update to the latest one. Ok, I'm willing to do that... but it looks like Sun (now Oracle) will happily let you download the latest firmware DVD (3.3.0), but it will not let you download the transition release (2.0) if you don't have a support contract. Well, I actuall don't care at all about the servers' management controllers (we don't even use them), so upgrading from ELOM to ILOM is totally irrelevant to me; but I need to update the servers' BIOS. So my question is: can I update the servers' BIOS to the latest version without doing the full ELOM-to-ILOM migration, or will this not work (or even make the servers unusable)? Do BIOS versions and SP ones need to be matched, or can one be updated without bothering with the other? Bonus question: if this whole ELOM-to-ILOM thing actually is needed in order to update the BIOS, can that 2.0 CD-ROM be obtained without having a support contract with Sun/Oracle (which we are definitely not going to sign, being that quite old hardware)? Update: I tried upgrading only the BIOS on one of the servers, and it didn't boot anymore. So it really looks like a full firmware upgrade is needed, and the management controller and BIOS versions should be kept in sync. So... where can I find that *&!£%$% 2.0 CD-ROM? Or at least the transition firmware that can be found on it?

• Is there a way to avoid Wacom Control Panel to stop showing in certain cases?

  - by S.gfx

  This is the problem: Suddenly, you double click on desktop Wacom tablet settings icon, and it won't show the dialog. It appears to be loaded as it's shown down in the Windows taskbar. I suspect it is caused by change of resolution or some setting, maybe suddenly it sets the origin of the panel dialog at some 3000 pixels to the right or something. I have dug in the wacom_tablet.dat file to see if I can fix it changing some value there, but it looks like a log, a history, more than a ini for settings. And anyway does not solve it. My solution is having always a very complete settings file done and backed up to restore (with Wacom utility for this, which in previous driver versions did not exist) when this happens, but it is counter-productive: You change the settings even per each project (and software) needs. I have seen it happenning with Cintiq 12", intuos4 A6, Graphires, Intuos 1. Is it just me, doing something weird every time? I doubt it, it's normal use, I am amazed that it seems no one else has had this problem (or nobody asked). It happens often with typical use. Maybe it's because I'm setting a shortcut in the desktop? Weird as it works perfect until some random moment. (I have dug in Wacom's forums and FAQs, then here, but nothing related to it. Neither in "related questions".) The thing happens in Win XP, 7, etc. It's done so for years in my experience, and several times at work, which is worse.

• Grub hangs at "Starting up ..." when USB flash card reader is plugged in (on Ubuntu Hardy)

  - by Laurence Gonsalves

  I have a PC with Ubuntu Hardy installed. The machine boots fine unless my USB flash card reader (one of those N-in-1 readers by MediaGear) is plugged in at startup. If the reader is plugged in, the boot process proceeds as normal until it gets to the screen that says "Starting up ...". At that point it just hangs forever. To work around this I currently leave the reader unplugged when booting, and then plug it back in after I see that Ubuntu is actually starting. This is annoying though, especially when I reboot the machine (typically for updates), forget to unplug the reader, and walk away only to come back hours later to find the machine hung. My guess is that the presence of the reader is confusing Grub about where to find the kernel. The weird thing is that Grub is on the same drive as the kernel I want it to boot so clearly the drive is still readable even when the flash card reader is plugged in. Is there some way I can tell Grub to never go looking on the flash card reader?

• Exchange SBS 2003 server stopped receiving mail over the weekend, senders getting "Relay access deni

  - by Charlie W.

  Firstly, I should say that I know my way around Windows very well, I don't really know the first thing about Exchange. I am trying to support a user that is running an SBS2003 Server with Exchange. Over the weekend, everyone sending something to any of his addresses gets an error message like the following: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <[email protected]>: Relay access denied (state 14). ----- Original message ----- Received: by 10.114.18.7 with SMTP id 7mr5572745war.127.1275423472120; Tue, 01 Jun 2010 13:17:52 -0700 (PDT) MIME-Version: 1.0 Sender: [email protected] Received: by 10.143.10.15 with HTTP; Tue, 1 Jun 2010 13:17:32 -0700 (PDT) From: My Name <[email protected]> Date: Tue, 1 Jun 2010 15:17:32 -0500 X-Google-Sender-Auth: XiPrP8Em_6Eb94EH9m84nJVGvCY Message-ID: <[email protected]> Subject: TEST To: Client <[email protected]> Content-Type: multipart/alternative; boundary=001636b1484ffe72470487fdaa5b There are a host of errors in the Application log, but nothing that leaps out at me as being obvious. But then again, I don't really know what I'm looking for. Any help would be greatly appreciated.

• Can't open cocoa emacs from terminal using open -a

  - by Shane

  I installed emacs on my MacBook Air running Mac OS X 10.6.5 from this site http://emacsformacosx.com/. I believe this is what used to be called cocoa emacs. I dragged it into my Application folder and it works fine when I run it from there. I want to be able to run it from the Terminal. After some googling, I tried open -a /Application/Emacs.app foo.txt (foo.txt was and existing file). I got two emacs windows - one with welcome screen and one with foo.txt loaded. I tried a few applications in the /Applications directory and they did not seem to behave like this. I had installed it using my own account (an admin account) so after doing ls -l on /Application I noticed that the owner and group were different from the other entries in this folder. I recursively changed the owner and group to root and wheel, like the others, but this did not help. The only thing that looks funny now is that there that ls -l show a @ character which has something to do with extended attributes but I don't know how to check these. Any suggestions on what to check next? Is using the open command the only to run the program? Can I simulate what it does using a shell script?

• Nginx, HAproxy, Unicorn, Rails and Node settings

  - by Julien Genestoux

  Our application is currently only a "regular" web app, with no fancy things like streaming HTTP or websockets. It's mostly a Rails app, served by a few (20 on 2 machines) Unicorn workers, proxied by a venerable nginx server which deals with load balancing. This has been working quite well for the past year and the app now serves between 400 and 800 requests per second at any point during the day. We're soon releasing 2 new APIs, which are both served by a Node application : a websocket one, as well as a long polling HTTP one. (the fancy thing like the Twitter streaming API where HTTP connections never end). They both use the same port on node and since the node app is stateless, we can certainly deploy a few of them to handle the traffic. The app (node) is now deployed in 5 instances and are now listening on 5 different 'private' ports on the same host. We need to put something in front of them to load balance, but also something that is able to deal with sockets (either websocket or HTTP streaming) which are intended to stay 'up' for days. The question is then : what? I read somewhere that HAProxy does a better job than Nginx at this. What do you recommend?

• Visual Studio 2010 Beta 2, built-in font smoothing

  - by L. Shaydariv

  I've just installed Visual Studio 2010 Beta 2 onto my Windows XP to evaluate it and check whether it meets my preferences the way it did before. Okay, I've temporary defeated an urgent bug with a strange workaround (I could not open any file from the Solution Explorer), and it left bad memories to me. But however, it's okay. The first thing I've seen just opening the code editor was ClearType font rendering. Wow, so unexpectedly. I must note that I do not use standard Windows rendering techniques, but I still prefer GDI++, a font renderer developed by Japanese developers. (GDI++ allows to render the fonts in Mac/Win-Safari style over entire Windows.) Personally for me, GDI++ reaches the great font-rendering results allowing me to use the Dejavu Sans Mono font with really nice smoothing in Visual Studio 2008 (VS 2005 too, though VS 2005 crashes in this case). But GDI++ cannot affect Visual Studio 2010 Beta 2 text editor - it uses ClearType (right?), and it does not care about the system font smoothing settings. It could be an editor based on WPF, right? So as far as I can see, I can't use GDI++ anymore because it uses Windows GDI(+) but no WPF? So I've got several questions: Is it possible to disable VS 2010 b2 built-in ClearType or override it with another font smoother? Is it possible to install a Safari-like font renderer for Visual Studio 2010 [betas]? Thanks a lot.

• Drobo-like linux file server - how do I do it?

  - by John Hunt

  I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

• DAS vs SAN storage for serving 2 to 4 nodes

  - by Luke404

  We currently have 4 Linux nodes with local storage, arranged in two active/passive pairs with storage mirrored using DRBD, running virtual machines (actually using Xen Hypervisor) for typical hosting workloads (mail, web, a couple VPS, etc.). We're approaching the (presumed) maximum IOPS of those servers, and we're planning to migrate to an external storage solution with two active nodes, with capacity for up to four active nodes. Since we're an all-Dell shop I've done some research and found the MD3200 / MD3200i products should be the ones we're looking for. We are pretty sure we won't be attaching more than 4 hosts on a single storage and I'm wondering if there is any clear advantage for one or the other. In theory I should be able to attach 4 SAS hosts to a single MD3200 (single links on a single controller MD3200, or dual redundant SAS links from each host to a dual-controller MD3200), or 4 iSCSI hosts to a single MD3200i (directly on its 4 GigE ports without any switch, again with dual links for the dual controller option). Both setups should let us implement live VM migration since all hosts can access all the LUNs at the same time, and also some shared filesystem like GFS2 or OCFS2. Also, both setups should allow full redundancy of the whole system (assuming dual controllers in the storage). One difference I can see is that the DAS solution is actually limited to 4 hosts while the iSCSI one should be able to grow to more hosts (adding two GigE switches to the mix). One point for the iSCSI solution is that it would allow us to start out with our current nodes and upgrade them at a later time (we can't add other SAS controllers, but they already have 4 GigE ports each). With the right (iSCSI|SAS) controllers I should be able to connect diskless nodes and boot them off the external storage which I think is a good thing (get rid of any local storage). On the other hand, I would have thought the SAS one to be cheaper but it seems like an MD3200 actually costs a little less than an MD3200i (?) (please note: I've used Dell gear in my examples since that's what we're looking for but I assume the same goes with other vendors) I would like to know if my assumptions above are correct, and if I'm missing any important difference between the two setups.

• Grant HTTP access based on unix user group

  - by Sander Marechal

  Is it possible to grant network access or HTTP access based on a user's group? At my company we want to set up an internal composer server using Satis to manage packages for the projects we write (e.g. on repository.mycompany.com), with the packages themselves in our SVN server (svn.mycompany.com). We have several webservers with many different users on them. Some users should be able to reach the composer and SVN server. Some should not. Users that should be able to reach these servers all belong to the same group. How can I set up Apache on the Composer and SVN server to only grant access to those users in that group? Alternatively, can I set up the webservers in such a way that only users from that group are able to make a connection to our Composer and SVN servers? The best thing we have come up with so far is using SSL client certificates. We simply place a client certificate on all servers which can be used to access Composer and SVN. Only the right usergroup will have read access to the certificate. A bit clunky but it may work. But I'm looking for something better.

• Which is more secure: Tomcat standalone or Tomcat behind Apache?

  - by NoozNooz42

  This question is not about performance, nor about load-balancing, etc. Which would be more secure: running Tomcat in standalone mode or running Tomcat behind apache? The thing is, Tomcat is written in Java and hence it is pretty much immune to buffer overrun/overflow (unless a buffer overrun in a C-written lib used by Tomcat can be triggered, but they're rare [the last I remember was in zlib, many many moons ago] and one heck of a hack to actually exploit), which gets rid of a lot of potential exploits. This page: http://wiki.apache.org/tomcat/FAQ/Security has this to say: There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue... there have been only theoretical vulnerabilities found. All of those were addressed even though there were no documented cases of actual exploitation of these vulnerabilities. This, combined with the fact that buffer overrun/overflow are pretty much non-existent in Java, makes me believe that Tomcat in standalone mode is pretty secure. In addition to that, I can install both Java and Tomcat on Linux without needing to be root. The only moment I need to be root is to set up a transparent port 8080 to port 80 forwarding (and 8443 to 443). Two iptables line as root, that's all root is needed for. (I don't know for Apache). Apache is much more used than Tomcat and definitely does not have a security track record as good as Tomcat. What would make Tomcat + Apache more secure? What would make Tomcat + Apache less secure? In short: which is more secure, Tomcat standalone or Tomcat with Apache? (remembering that performance aren't an issue here)

• What do the readonly attributes in diskpart really mean?

  - by marzipan

  I am wondering exactly what the meaning is of the "Read-only" disk and volume attributes that you can twiddle in diskpart on Windows 7. I am trying to set up an external USB drive as an installation medium for my own software, so I'd like to protect it against casual or inadvertent changes by users who it is given to, so they don't screw up the installation files they might need in the future. From what I can tell by experimentation with diskpart, the volume read-only attribute is actually stored on the physical disk somewhere, because I can set it and it shows up when I take the drive to another machine. This is great because my users can't (easily) change any of the files on the volume, or format it from Windows explorer. However, the disk read-only attribute seems to be just an aspect of how the current machine is accessing the drive. When I set it I can no longer delete the volume in the disk via Disk Management, but when I take the drive to another machine, the attribute is no longer set and in Disk Management I can delete the volume on the disk. I guess I'm not that worried about my users doing that, but I am annoyed that I don't understand what these attributes are really doing. Another thing that I don't understand is that the "volume" read-only attribute actually seems to be global to the disk - if I have two volumes on the disk, and I set the readonly flag on one of them, then it gets set on the other one too. ?!? I have the feeling I'm not searching for the right docs - all I'm finding is diskpart docs that give the syntax for twiddling these attributes, not what they really mean. Any pointers would be very welcome! Thanks, Asa

• winbind failing after a semi-random amount of time

  - by The Digital Ninja

  I have winbind set up to authenticate to our AD for samba shares. This is the third such server, and the only one having any issues. It seems after a random amount of time samba shares will just stop working. Winbind processes seem to be running but restarting them seems to fix the issue for a while. Looking at the logs have been kind of hit an miss and I don't know exactly when it fails. One interesting thing is that it seems to be pulling from another domain controller that it shoudlnt. I censored out the domain name in this example. But isnt there some way to block authentication to a domain? I'm not sure if this is a symptom or a cause of the issue.

• Adding a GET parameter to URL causes 404 error

  - by Adrian Grigore

  I'm trying to install the syntaxhighlightter evolved plugin to my wordpress blog. I've uploaded and activated the plugin, but it did not work. I've looked into the page source code and found out that the plugin style is loaded from the following URL: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css?ver=2.0.320 This causes a 404 error (page not found). The strange thing though is that when I remove the GET parameters, the CSS loads ok: http://devermind.com/wp-content/plugins/syntaxhighlighter/syntaxhighlighter/styles/shCore.css What could be causing this problem and how can I fix this? Unfortunately I don't know how to make wordpress drop the GET parameters when loading the stylesheet. EDIT: As I just found out, this happens only in Firefox (3.0.11). IE loads both URLs above just fine. Not that this would be of any help though, so any suggestions would be appreciated. SECOND EDIT: I tried this on my laptop and it works fine with Firefox 3.08. So this really seems to be a browser problem after all.

• Blending Background for Polar Distortion in GIMP

  - by Chris S

  I followed a tutorial to perform a polar distortion on a panoramic image. The instructions are geared for Photoshop but seem to mostly apply to GIMP as well. The only thing I couldn't really figure out was how they were able to automatically fill in the area around the circle by "extending" the border of the circle. e.g. In GIMP, performing the polar distortion leaves a black white canvas around the circle, not the attractive blended background shown in the tutorial. Is there an easy way to implement this? The only way I found was to reserve half of the "square" as blank canvas and then manually copy the image's top row of pixels over this empty portion. Then, after the polar distortion, I crop out the extra area. Although this achieves the effect, it seems a bit awkward. How do you stretch selections? Ideally, I just want to select the top row and stretch it vertically until it fills in half of the canvas. Instead I had to manaully copy, paste, translate, etc.

• Is this a solution for having multiple SSL certificates on the same IP

  - by Saif Bechan

  I am running CentOS running on a VPS. I read some guides on having multiple SSL certificates on the same system, but I can not get the basics to work. The guide I got that makes the most sense to me is the doing the following. In CentOS I can make virtual NIC's. So I made 2 virtual NIC's to start with. 192.168.10.1, 192.168.10.2. Now I work in ISP manager Pro, so this is listening on my primary ip 1.1.1.1 For each website I have them listening on 192.168.10.1:80, 192.168.10.1:443 In the hosts file I made the following 2 entries 192.168.10.1 1st.com 192.168.10.2 2nd.com Now the strange thing is that when I browser to 1st.com I do not get the website located at 192.168.10.1, I get the website located at my prim IP 1.1.1.1 Should I do something like forwarding or routing for this setup to work? And the basic question: Will this setup even work? Are the SSL certificates based on the IP adress, or are the based on the host name, 1st.com and 2nd.com.

• How can i use the `eject` command on a computer i have SSH'd into?

  - by will

  So if i do eject on my machine, it works exactly as expected, however, if i ssh into the machine next to me, and do the same thing, it does not work... my computer: eject: using default device `cdrom' eject: device name is `cdrom' eject: expanded name is `/dev/cdrom' eject: `/dev/cdrom' is a link to `/dev/sr0' eject: `/dev/sr0' is not mounted eject: `/dev/sr0' is not a mount point eject: checking if device "/dev/sr0" has a removable or hotpluggable flag eject: `/dev/sr0' is not a multipartition device eject: trying to eject `/dev/sr0' using CD-ROM eject command eject: CD-ROM eject command succeeded other computer: eject: using default device `cdrom' eject: device name is `cdrom' eject: expanded name is `/dev/cdrom' eject: `/dev/cdrom' is a link to `/dev/sr0' eject: `/dev/sr0' is not mounted eject: `/dev/sr0' is not a mount point eject: checking if device "/dev/sr0" has a removable or hotpluggable flag eject: `/dev/sr0' is not a multipartition device eject: unable to open `/dev/sr0' if i look in the /dev/ dir, then i find cdrom which is a symlink to sr0 - as mentioned by the verbose outputs of eject -v. On my machine, if i try and look at it, if the drive is open, it will close it, and then give this: $ less sr0 sr0 is not a regular file (use -f to see it) so $ less -f sr0 sr0: No medium found but if i do it on the other computer, $ less -f sr0 sr0: Permission denied so i look at the files more, and get this on both machines: $ ls -la sr0 brw-rw----+ 1 root cdrom 11, 0 Nov 12 10:13 sr0 Does anyone know a way around this? I do not have root access.
