• What's the best way to block IP spoofing on a layer 3 switch?

  - by toupeira

  We're hosting Dedicated Servers and are currently using old 3com switches with IP-based ACLs. So each port has an ACL that allows all IP addresses assigned to this customer, and blocks everything else. But now 3com was bought by HP, and the follow-up model only supports basic ACL that aren't flexible enough to both allow certain IPs while blocking others. Looking at other switches in a similar price-range, we've found that most of them have similar problems or don't offer any ACL features at all. I assume this could also somehow be done with VLANs, but if I understand this correctly we'd still need some kind of ACL to actually specify the valid IP addresses for each port. What do you use to make sure your customers don't use unassigned IP addresses? Or what switches can you recommend that have flexible ACL functionality?

• Block SMTP connections from mail domains which don't themselves accept SMTP connection.

  - by bignose

  I'm administrating a mail service for a small business. Their mail host's internet connection is an ADSL service with a permanent IP address. Unfortunately, many misconfigured mail systems will happily deliver to this host, but, when the host attempts to send mail back (e.g. a bounce notice, or a normal response from someone), the original sender refuses to receive connections from this host. That misconfiguration makes their system a one-way mail sender, which is a problem. How can I configure Postfix on this customer's mail host to refuse SMTP sessions that declare a sender domain which itself refuses SMTP from this host? That is, if the SMTP client declares a domain that we can't make SMTP connections back to, then there's not much point accepting the incoming connection in the first place. I'm imagining a late check (after the low-cost checks to winnow most of the rubbish connections) that keeps the client on the other end while it attempts an SMTP client connection back to the declared domain of the sender. If that connection is rejected, the incoming one is also rejected. I'm also open to other suggestions for how this problem might be addressed (short of not using this mail host at all, which isn't an option).

• How to block this URL pattern in Varnish VCL?

  - by iTech

  My website is getting badly hit by spambots and scrappers, I am using Cloudflare but the problem still remains there. The problem is spambots accessing non-existing urls causing a lot of load to my drupal backend which goes all the way and bootstraps db just to serve a 404 error doc. I cant simply dish out non-drupal 404's for all page not found errors, as I need to have drupal catch them. Since, varnish is in front it can check if the bot is acting nice and asking for valid url - if not it servers them a 404 or 403. These bots are causing errors using this pattern : http://www.megaleecher.net/http:/www.megaleecher.net/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_S/Using_iPhone_As_USB_Mass_Storage Now, pls. suggest a regex varnbisg VCL directive which catches this URL pattern and serves a 404 error from varnish, preventing it from reaching apache/drupal ?

• Do large corporations block jQuery content on web pages?

  - by Max Vernon

  We are currently redesigning our website. The company we've hired to do the redesign is advocating the use of jQuery to render the pages dynamically. Our SEO specialist is under the impression that many larger corporations may have jQuery blocked in their proxies to prevent their users from visiting sites like Facebook. Is this something you are aware of? Forgive me if this is off topic for SF.SE!

• How to make Plesk NOT block the browser password auto-complete feature?

  - by gabrielradic

  All versions of the Plesk control panel software always had this "feature" where they disable the browser password auto-complete feature. Sure, they argue it's a security measure, but it's really not. So, how can one force the Plesk login page behave and let the browser remember the login and password fields? Thanks. PS: I am trying to change the actual page, not hack my browser.

• Different font SIZES in a Text Editor, based on Script(Alphabet) type (ie. per Unicode Code-Block)

  - by fred.bear

  Some non-Latin-based scripts(alphabets) have more detail in their glyphs than do the Latin-based-script equivalents, and typically need a larger font to give the same degree of legibility (resolution-wise). Sometimes, both script types need to be present in the same file. Notepad++ allows different font SIZES (and colour, etc) courtesy of syntax-highlighting. This allows me to display larger-fonted non-Latin-based script in a // BIG-FONT comment. Although this has been quite handy for me in some situations, it is quite limited. A Word Processor can handle this scenario, but I'm not interested in that. I want a nice simple(?) plain(?) Text Editor to do it... on a per script-type basis... eg. mixing Latin-1 and Devanagari (and Mandarin, and ... Such a thing may not exits, but Notepad++ has shown that a simple(?) plain(?) Text Editor is capable of it. Does anyone know of such a Text Editor? ...Q. Why not a Word Processor? ...A. Because GCC and Python don't like that format! but UTF-8 is fine.

• How do I block my ISP from framing websites?

  - by PJB

  I've noticed recently, as of today, that all the websites I visit (except for a specific few sites such as Google) are all put into a frame. I'm not sure what the reason for this is, there are no ads displayed and everything appears normal. The only reason I found out is because the headers weren't loading correctly and none of the page titles showed up properly - I quickly checked the source code and saw that instead of the source of the page I was expecting to see, there was a single line with a frame. I first thought maybe somekind of trojan, but after going through various checks I've determined it's my ISP and/or somekind of Internet Registry (I traced the IP shown in the source code) What can be done to prevent this frame, short of using a VPN? I feel like I am being spied on. PS: I'm located in South Korea.

• Help with converting an XML into a 2D level (Actionscript 3.0)

  - by inzombiak

  I'm making a little platformer and wanted to use Ogmo to create my level. I've gotten everything to work except the level that my code generates is not the same as what I see in Ogmo. I've checked the array and it fits with the level in Ogmo, but when I loop through it with my code I get the wrong thing. I've included my code for creating the level as well as an image of what I get and what I'm supposed to get. EDIT: I tried to add it, but I couldn't get it to display properly Also, if any of you know of better level editors please let me know. xmlLoader.addEventListener(Event.COMPLETE, LoadXML); xmlLoader.load(new URLRequest("Level1.oel")); function LoadXML(e:Event):void { levelXML = new XML(e.target.data); xmlFilter = levelXML.* for each (var levelTest:XML in levelXML.*) { crack = levelTest; } levelArray = crack.split(''); trace(levelArray); count = 0; for(i = 0; i <= 23; i++) { for(j = 0; j <= 35; j++) { if(levelArray[i*36+j] == 1) { block = new Platform; s.addChild(block); block.x = j*20; block.y = i*20; count++; trace(i); trace(block.x); trace(j); trace(block.y); } } } trace(count);

• How to force a DIV block to extend to the bottom of a page, even if it has no content?

  - by Sir Psycho

  Hi, I'm trying to get the content div to stretch all the way to the bottom of the page but so far, its only stretching if theres actual content to display. The reason I want to do this is so if there isn't much content to display, the vertical border still goes all the way down. Here is my code <body> <form id="form1"> <div id="header"> <a title="Home" href="index.html" /> </div> <div id="menuwrapper"> <div id="menu"> </div> </div> <div id="content"> </div> and my CSS body { font-family: Trebuchet MS, Verdana, MS Sans Serif; font-size:0.9em; margin:0; padding:0; } div#header { width: 100%; height: 100px; } #header a { background-position: 100px 30px; background: transparent url(site-style-images/sitelogo.jpg) no-repeat fixed 100px 30px; height: 80px; display: block; } #header, #menuwrapper { background-repeat: repeat; background-image: url(site-style-images/darkblue_background_color.jpg); } #menu #menuwrapper { height:25px; } div#menuwrapper { width:100% } #menu, #content { width:1024px; margin: 0 auto; } div#menu { height: 25px; background-color:#50657a; } Thanks for taking a looksi

• Silverlight: How can I built an overview display block for any XAML?

  - by Ryan Bates

  Hi all, I am trying to create a generic "overview" control for any XAML. A good example of the desired effect would be on Google Maps or Bing maps: The main map zooms into some content, while a small "overview" block is docked to one of the map corners, showing the user where he/she is zoomed into. My content is all placed inside a <Canvas>, which can then be scaled and zoomed with transforms. While the user does this kind of navigation, I would like to give them a visual indication of where they are in the larger context of the content. I have tried to take a 'screenshot' of the XAML before the user starts navigating, i.e. create a WriteableBitmap wbImageData = new WriteableBitmap(TheCanvas, null); and then displaying it in an Image. Based on the user's scrolling and zooming activity, a Rectangle displays which part of the content is currently visible in the display area. This works OK-ish (still clunky), but the image has to be redone everytime the content changes. Is there a simple way to create this kind of preview, or does anyone know of a component that does it? Thanks!

• Creating a tiled map with blender

  - by JamesB

  I'm looking at creating map tiles based on a 3D model made in blender, The map is 16 x 16 in blender. I've got 4 different zoom levels and each tile is 100 x 100 pixels. The entire map at the most zoomed out level is 4 x 4 tiles constructing an image of 400 x 400. The most zoomed in level is 256 x 256 obviously constructing an image of 25600 x 25600 What I need is a script for blender that can create the tiles from the model. I've never written in python before so I've been trying to adapt a couple of the scripts which are already there. So far I've come up with a script, but it doesn't work very well. I'm having real difficulties getting the tiles to line up seamlessly. I'm not too concerned about changing the height of the camera as I can always create the same zoomed out tiles at 6400 x 6400 images and split the resulting images into the correct tiles. Here is what I've got so far... #!BPY """ Name: 'Export Map Tiles' Blender: '242' Group: 'Export' Tip: 'Export to Map' """ import Blender from Blender import Scene,sys from Blender.Scene import Render def init(): thumbsize = 200 CameraHeight = 4.4 YStart = -8 YMove = 4 XStart = -8 XMove = 4 ZoomLevel = 1 Path = "/Images/Map/" Blender.drawmap = [thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path] def show_prefs(): buttonthumbsize = Blender.Draw.Create(Blender.drawmap[0]); buttonCameraHeight = Blender.Draw.Create(Blender.drawmap[1]) buttonYStart = Blender.Draw.Create(Blender.drawmap[2]) buttonYMove = Blender.Draw.Create(Blender.drawmap[3]) buttonXStart = Blender.Draw.Create(Blender.drawmap[4]) buttonXMove = Blender.Draw.Create(Blender.drawmap[5]) buttonZoomLevel = Blender.Draw.Create(Blender.drawmap[6]) buttonPath = Blender.Draw.Create(Blender.drawmap[7]) block = [] block.append(("Image Size", buttonthumbsize, 0, 500)) block.append(("Camera Height", buttonCameraHeight, -0, 10)) block.append(("Y Start", buttonYStart, -10, 10)) block.append(("Y Move", buttonYMove, 0, 5)) block.append(("X Start", buttonXStart,-10, 10)) block.append(("X Move", buttonXMove, 0, 5)) block.append(("Zoom Level", buttonZoomLevel, 1, 10)) block.append(("Export Path", buttonPath,0,200,"The Path to save the tiles")) retval = Blender.Draw.PupBlock("Draw Map: Preferences" , block) if retval: Blender.drawmap[0] = buttonthumbsize.val Blender.drawmap[1] = buttonCameraHeight.val Blender.drawmap[2] = buttonYStart.val Blender.drawmap[3] = buttonYMove.val Blender.drawmap[4] = buttonXStart.val Blender.drawmap[5] = buttonXMove.val Blender.drawmap[6] = buttonZoomLevel.val Blender.drawmap[7] = buttonPath.val Export() def Export(): scn = Scene.GetCurrent() context = scn.getRenderingContext() def cutStr(str): #cut off path leaving name c = str.find("\\") while c != -1: c = c + 1 str = str[c:] c = str.find("\\") str = str[:-6] return str #variables from gui: thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path = Blender.drawmap XMove = XMove / ZoomLevel YMove = YMove / ZoomLevel Camera = Scene.GetCurrent().getCurrentCamera() Camera.LocZ = CameraHeight / ZoomLevel YStart = YStart + (YMove / 2) XStart = XStart + (XMove / 2) #Point it straight down Camera.RotX = 0 Camera.RotY = 0 Camera.RotZ = 0 TileCount = 4**ZoomLevel #Because the first thing we do is move the camera, start it off the map Camera.LocY = YStart - YMove for i in range(0,TileCount): Camera.LocY = Camera.LocY + YMove Camera.LocX = XStart - XMove for j in range(0,TileCount): Camera.LocX = Camera.LocX + XMove Render.EnableDispWin() context.extensions = True context.renderPath = Path #setting thumbsize context.imageSizeX(thumbsize) context.imageSizeY(thumbsize) #could be put into a gui. context.imageType = Render.PNG context.enableOversampling(0) #render context.render() #save image ZasString = '%s' %(int(ZoomLevel)) XasString = '%s' %(int(j+1)) YasString = '%s' %(int((3-i)+1)) context.saveRenderedImage("Z" + ZasString + "X" + XasString + "Y" + YasString) #close the windows Render.CloseRenderWindow() try: type(Blender.drawmap) except: #print 'initialize extern variables' init() show_prefs()

• mdadm: Win7-install created a boot partition on one of my RAID6 drives. How to rebuild?

  - by EXIT_FAILURE

  My problem happened when I attempted to install Windows 7 on it's own SSD. The Linux OS I used which has knowledge of the software RAID system is on a SSD that I disconnected prior to the install. This was so that windows (or I) wouldn't inadvertently mess it up. However, and in retrospect, foolishly, I left the RAID disks connected, thinking that windows wouldn't be so ridiculous as to mess with a HDD that it sees as just unallocated space. Boy was I wrong! After copying over the installation files to the SSD (as expected and desired), it also created an ntfs partition on one of the RAID disks. Both unexpected and totally undesired! . I changed out the SSDs again, and booted up in linux. mdadm didn't seem to have any problem assembling the array as before, but if I tried to mount the array, I got the error message: mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg: EXT4-fs (md0): ext4_check_descriptors: Block bitmap for group 0 not in group (block 1318081259)! EXT4-fs (md0): group descriptors corrupted! I then used qparted to delete the newly created ntfs partition on /dev/sdd so that it matched the other three /dev/sd{b,c,e}, and requested a resync of my array with echo repair > /sys/block/md0/md/sync_action This took around 4 hours, and upon completion, dmesg reports: md: md0: requested-resync done. A bit brief after a 4-hour task, though I'm unsure as to where other log files exist (I also seem to have messed up my sendmail configuration). In any case: No change reported according to mdadm, everything checks out. mdadm -D /dev/md0 still reports: Version : 1.2 Creation Time : Wed May 23 22:18:45 2012 Raid Level : raid6 Array Size : 3907026848 (3726.03 GiB 4000.80 GB) Used Dev Size : 1953513424 (1863.02 GiB 2000.40 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Mon May 26 12:41:58 2014 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 4K Name : okamilinkun:0 UUID : 0c97ebf3:098864d8:126f44e3:e4337102 Events : 423 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 8 32 1 active sync /dev/sdc 2 8 48 2 active sync /dev/sdd 3 8 64 3 active sync /dev/sde Trying to mount it still reports: mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so and dmesg: EXT4-fs (md0): ext4_check_descriptors: Block bitmap for group 0 not in group (block 1318081259)! EXT4-fs (md0): group descriptors corrupted! I'm a bit unsure where to proceed from here, and trying stuff "to see if it works" is a bit too risky for me. This is what I suggest I should attempt to do: Tell mdadm that /dev/sdd (the one that windows wrote into) isn't reliable anymore, pretend it is newly re-introduced to the array, and reconstruct its content based on the other three drives. I also could be totally wrong in my assumptions, that the creation of the ntfs partition on /dev/sdd and subsequent deletion has changed something that cannot be fixed this way. My question: Help, what should I do? If I should do what I suggested , how do I do that? From reading documentation, etc, I would think maybe: mdadm --manage /dev/md0 --set-faulty /dev/sdd mdadm --manage /dev/md0 --remove /dev/sdd mdadm --manage /dev/md0 --re-add /dev/sdd However, the documentation examples suggest /dev/sdd1, which seems strange to me, as there is no partition there as far as linux is concerned, just unallocated space. Maybe these commands won't work without. Maybe it makes sense to mirror the partition table of one of the other raid devices that weren't touched, before --re-add. Something like: sfdisk -d /dev/sdb | sfdisk /dev/sdd Bonus question: Why would the Windows 7 installation do something so st...potentially dangerous? Update I went ahead and marked /dev/sdd as faulty, and removed it (not physically) from the array: # mdadm --manage /dev/md0 --set-faulty /dev/sdd # mdadm --manage /dev/md0 --remove /dev/sdd However, attempting to --re-add was disallowed: # mdadm --manage /dev/md0 --re-add /dev/sdd mdadm: --re-add for /dev/sdd to /dev/md0 is not possible --add, was fine. # mdadm --manage /dev/md0 --add /dev/sdd mdadm -D /dev/md0 now reports the state as clean, degraded, recovering, and /dev/sdd as spare rebuilding. /proc/mdstat shows the recovery progress: md0 : active raid6 sdd[4] sdc[1] sde[3] sdb[0] 3907026848 blocks super 1.2 level 6, 4k chunk, algorithm 2 [4/3] [UU_U] [>....................] recovery = 2.1% (42887780/1953513424) finish=348.7min speed=91297K/sec nmon also shows expected output: ¦sdb 0% 87.3 0.0| > |¦ ¦sdc 71% 109.1 0.0|RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR > |¦ ¦sdd 40% 0.0 87.3|WWWWWWWWWWWWWWWWWWWW > |¦ ¦sde 0% 87.3 0.0|> || It looks good so far.
