• Why is everything crashing?

  - by Kopkins

  I've been using Ubuntu for a while now and I love it, I wouldn't think of using another OS unless I can't fix this issue. The install I'm on is only around a month and a half old. I'm running 12.04 64bit on a 8,1 MBP. Up until around 2 weeks ago everything was running smoothly. Around then applications started crashing and weird things started happening. At first I thought it was just certain applications. The first thing to start giving me trouble was compiz. Occasionally compiz will stop decorating windows and lost many other functionalities. running compiz --replace fixes this, but I don't feel like doing it usually once a day. The other thing with this is that after running compiz --replace, my conky window gets lost somewhere and so I run killall conky && conky -c .conkyrc. But this isn't with just a couple applications, it seems like it is proliferating through my system. Last week fontforge started crashing while doing whatever task. So I ended up unable to finish what I was working on to completeness. Didn't find a fix. Today rhythmbox started crashing. Whenever I try to play anything, Rhythmbox becomes unresponsive and needs to be forced to close. When I try to do certain things with the disk utility, it crashes. I get the Ubuntu has experienced an internal error message much more often than I would like. Frequently applications stop appearing in the launcher. Wine almost never does anymore. After not being active for a little while, thunderbird can only fetch my mail after restarting wireless, sudo rmmod b43 && sudo modprobe b43 Occasionally some of my startup apps don't start. What is my best option here? Could they be bugs? I don't want to submit a ton of vague bug reports. Reinstall? switch OS? Thank you to anyone who responds. Kopkins

• Best system for creating a 2d racing track

  - by tesselode

  I am working a 2D racing game and I'm trying to figure out what is the best way to define the track. At the very least, I need to be able to create a closed circuit with any amount of turns at any angle, and I need vehicles to collide with the edges of the track. I also want the following things to be true if possible (but they are optional): The code is simple and free of funky workarounds and extras I can define all of the parts of the track (such as turns) relative to the previous parts I can predict the exact position of the road at a certain point (that way I can easily and cleanly make closed circuits) Here are my options: Use a set of points. This is my current system. I have a set of turns and width changes that the track is supposed to make over time. I have a point which I transform according to these instructions, and I place a point every 5 steps or so, depending on how precise I want the track to be. These points make up the track. The main problem with this is the discrepancy between the collisions and the way the track is drawn. I won't get into too much detail, but the picture below shows what is happening (although it is exaggerated a bit). The blue lines are what is drawn, the red lines are what the vehicle collides with. I could work around this, but I'd rather avoid funky workaround code. Beizer curves. These seem cool, but my first impression of them is that they'll be a little daunting to learn and are probably too complicated for my needs. Some other kind of curve? I have heard of some other kinds of curves; maybe those are more applicable. Use Box2D or another physics engine. Instead of defining the center of the track, I could use a physics engine to define shapes that make up the road. The downside to this, however, is that I have to put in a little more work to place the checkpoints. Something completely different. Basically, what is the simplest system for generating a race track that would allow me to create closed circuits cleanly, handle collisions, and not have a ton of weird code?

• HTML5 platformer collision detection problem

  - by fnx

  I'm working on a 2D platformer game, and I'm having a lot of trouble with collision detection. I've looked trough some tutorials, questions asked here and Stackoverflow, but I guess I'm just too dumb to understand what's wrong with my code. I've wanted to make simple bounding box style collisions and ability to determine on which side of the box the collision happens, but no matter what I do, I always get some weird glitches, like the player gets stuck on the wall or the jumping is jittery. You can test the game here: Platform engine test. Arrow keys move and z = run, x = jump, c = shoot. Try to jump into the first pit and slide on the wall. Here's the collision detection code: function checkCollisions(a, b) { if ((a.x > b.x + b.width) || (a.x + a.width < b.x) || (a.y > b.y + b.height) || (a.y + a.height < b.y)) { return false; } else { handleCollisions(a, b); return true; } } function handleCollisions(a, b) { var a_top = a.y, a_bottom = a.y + a.height, a_left = a.x, a_right = a.x + a.width, b_top = b.y, b_bottom = b.y + b.height, b_left = b.x, b_right = b.x + b.width; if (a_bottom + a.vy > b_top && distanceBetween(a_bottom, b_top) + a.vy < distanceBetween(a_bottom, b_bottom)) { a.topCollision = true; a.y = b.y - a.height + 2; a.vy = 0; a.canJump = true; } else if (a_top + a.vy < b_bottom && distanceBetween(a_top, b_bottom) + a.vy < distanceBetween(a_top, b_top)) { a.bottomCollision = true; a.y = b.y + b.height; a.vy = 0; } else if (a_right + a.vx > b_left && distanceBetween(a_right, b_left) < distanceBetween(a_right, b_right)) { a.rightCollision = true; a.x = b.x - a.width - 3; //a.vx = 0; } else if (a_left + a.vx < b_right && distanceBetween(a_left, b_right) < distanceBetween(a_left, b_left)) { a.leftCollision = true; a.x = b.x + b.width + 3; //a.vx = 0; } } function distanceBetween(a, b) { return Math.abs(b-a); }

• NVIDIA Additional Drivers Empty - maximum resolution 640x480 - Driver disappears

  - by Hannibal

  EDIT: Optimus card. For resolution please read this thread: "You do not appear to be using the nvidia x server"(screenshot included) And this: Ubuntu 11.10 problem with Nvidia Thanks! I know, I know yet another NVIDIA question. So I did all the research. I uninstalled and installed nvidia-settings and drivers and nvidia-current from PPE repositories which are the most updated ones. I executed nvidia-xconfig. I have two major problems. One: Additional Drivers setting is empty! It doesn't contain any driver although one is installed. I have executed apt-get update too. But still the list is empty. Two: If I execute nvidia-xconfig it will properly configure an xorg.conf file. I restart but the maximum resolution I got is 640x480. I tried the xrandr but I can't add any resolution to display LVDS1. Some weird error occurs. So I can't add a proprietary driver and I can't boot in with the xorg file created by Nvidia... What can I do? With some work ( unistall nvidia-current and install libgl1-mesa-glx I was able to activate some kind of usage of my card because the resolution got better... and I added bumbelbee to because I have multiple video cards... ) but still the list is empty. I don't know what to do at this point??!!! Also: this is the most important part. When I first installed my ubuntu yesterday 11.10 one I saw the driver!! The driver was there... And then I ofc updated every package from internet.. And after that it was gone. And I can't bring it back. So there must be something wrong with one of the updates. But which???? Thanks for any extra info you can provide! I'm really desperate to solve this issue.

• A Simple Entity Tagger

  - by Elton Stoneman

  In the REST world, ETags are your gateway to performance boosts by letting clients cache responses. In the non-REST world, you may also want to add an ETag to an entity definition inside a traditional service contract – think of a scenario where a consumer persists its own representation of your entity, and wants to keep it in sync. Rather than load every entity by ID and check for changes, the consumer can send in a set of linked IDs and ETags, and you can return only the entities where the current ETag is different from the consumer’s version.  If your entity is a projection from various sources, you may not have a persistent ETag, so you need an efficient way to generate an ETag which is deterministic, so an entity with the same state always generates the same ETag. I have an implementation for a generic ETag generator on GitHub here: EntityTagger code sample. The essence is simple - we get the entity, serialize it and build a hash from the serialized value. Any changes to either the state or the structure of the entity will result in a different hash. To use it, just call SetETag, passing your populated object and a Func<> which acts as an accessor to the ETag property: EntityTagger.SetETag(user, x => x.ETag); The implementation is all in at 80 lines of code, which is all pretty straightforward: var eTagProperty = AsPropertyInfo(eTagPropertyAccessor); var originalETag = eTagProperty.GetValue(entity, null); try { ResetETag(entity, eTagPropertyAccessor); string json; var serializer = new DataContractJsonSerializer(entity.GetType()); using (var stream = new MemoryStream()) { serializer.WriteObject(stream, entity); json = Encoding.UTF8.GetString(stream.GetBuffer(), 0, (int)stream.Length); } var guid = GetDeterministicGuid(json); eTagProperty.SetValue(entity, guid.ToString(), null); //... There are a couple of helper methods to check if the object has changed since the ETag value was last set, and to reset the ETag. This implementation uses JSON to do the serializing rather than XML. Benefit - should be marginally more efficient as your hashing a much smaller serialized string; downside, JSON doesn't include namespaces or class names at the root level, so if you have two classes with the exact same structure but different names, then instances which have the same content will have the same ETag. You may want that behaviour, but change to use the XML DataContractSerializer if you think that will be an issue. If you can persist the ETag somewhere, it will save you server processing to load up the entity, but that will only apply to scenarios where you can reliably invalidate your ETag (e.g. if you control all the entry points where entity contents can be updated, then you can calculate and persist the new ETag with each update).

• How to snap a 2D Quad to the mouse cursor using OpenGL 3.0?

  - by NoobScratcher

  I've been having issues trying to snap a 2D Quad to the mouse cursor position I'm able : 1.) To get values into posX, posY, posZ 2.) Translate with the values from those 3 variables But the quad positioning I'm not able to do correctly in such a way that the 2D Quad is near the mouse cursor using those values from those 3 variables eg."posX, posY, posZ" I need the mouse cursor in the center of the 2D Quad. I'm hoping someone can help me achieve this. I've tried searching around with no avail. Heres the function that is ment to do the snapping but instead creates weird flicker or shows nothing at all only the 3d models show up : void display() { glClearColor(0.0,0.0,0.0,1.0); glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); for(std::vector<GLuint>::iterator I = cube.begin(); I != cube.end(); ++I) { glCallList(*I); } if(DrawArea == true) { glReadPixels(winX, winY, 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &winZ); cerr << winZ << endl; glGetDoublev(GL_MODELVIEW_MATRIX, modelview); glGetDoublev(GL_PROJECTION_MATRIX, projection); glGetIntegerv(GL_VIEWPORT, viewport); gluUnProject(winX, winY, winZ , modelview, projection, viewport, &posX, &posY, & posZ); glBindTexture(GL_TEXTURE_2D, DrawAreaTexture); glPixelStorei(GL_UNPACK_ALIGNMENT, 1); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_DECAL); glTexImage2D (GL_TEXTURE_2D, 0, GL_RGB, DrawAreaSurface->w, DrawAreaSurface->h, 0, GL_RGBA, GL_UNSIGNED_BYTE, DrawAreaSurface->pixels); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, DrawAreaTexture); glTranslatef(posX , posY, posZ); glBegin(GL_QUADS); glTexCoord2f (0.0, 0.0); glVertex3f(0.5, 0.5, 0); glTexCoord2f (1.0, 0.0); glVertex3f(0, 0.5, 0); glTexCoord2f (1.0, 1.0); glVertex3f(0, 0, 0); glTexCoord2f (0.0, 1.0); glVertex3f(0.5, 0, 0); glEnd(); } SwapBuffers(hDC); } I'm using : OpenGL 3.0 WIN32 API C++ GLSL if you really want the full source here it is - http://pastebin.com/1Ncm9HNf , Its pretty messy.

• Why do I have to divide the origin of a quad by 4 instead of 2?

  - by vinzBad

  I'm currently transitioning from C#/XNA to C#/OpenTK but I'm getting stuck at the basics. So I have this Sprite-Class: public static bool EnableDebugDraw = true; public float X; public float Y; public float OriginX = 0; public float OriginY = 0; public float Width = 0.1f; public float Height = 0.1f; public Color TintColor = Color.Red; float _layerDepth = 0f; public void Render() { Vector2[] corners = { new Vector2(X-OriginX,Y-OriginY), //top left new Vector2(X +Width -OriginX,Y-OriginY),//top right new Vector2(X +Width-OriginX,Y+Height-OriginY),//bottom rigth new Vector2(X-OriginX,Y+Height-OriginY)//bottom left }; GL.Color3(TintColor); GL.Begin(BeginMode.Quads); { for (int i = 0; i < 4; i++) GL.Vertex3(corners[i].X,corners[i].Y,_layerDepth); } GL.End(); if (EnableDebugDraw) { GL.Color3(Color.Violet); GL.PointSize(3); GL.Begin(BeginMode.Points); { for (int i = 0; i < 4; i++) GL.Vertex2(corners[i]); } GL.End(); GL.Color3(Color.Green); GL.Begin(BeginMode.Points); GL.Vertex2(X + OriginX, Y + OriginY); GL.End(); } With the following setup I try to set the origin of the quad to the middle of the quad. _sprite.OriginX = _sprite.Width / 2; _sprite.OriginY = _sprite.Height / 2; but this sets the origin to the upper right corner of the quad, so i have to _sprite.OriginX = _sprite.Width / 4; _sprite.OriginY = _sprite.Height / 4; However this is not the intended behaviour, could you advise me how I fix this?

• Introduction to Agile Development

  - by Grant Fritchey

  Even though my current job is a little weird, I still consider myself to be a DBA. I didn’t start that way in IT. I came through support and into development. I loved development. There was a constant struggle to attempt to improve your code, your understanding, and, most importantly, the process of development itself. Development can be slow and tedious. Left alone, developers can simply disappear to build a project and not come back for two years, at which time they deliver it. But, maybe that software isn’t what you wanted, or it’s no longer needed, or who knows what. So developers are constantly attempting to improve their processes in order to deliver more relavent software quicker (something DBAs could learn about). I really admire it. One of the many processes that has come out of that constant striving is known as Agile. As the name implies, Agile development attempts to come up with a quick, fast turning, business aware, well, for want of a word, agile, process that is more responsive to the needs of the business. There are tons and tons of books and blogs and videos on the subject that can get you going. But, Agile isn’t easy (note, Easy is not part of the name). Agile processes can be hard. I’ve worked on multiple agile teams, some successful, some not. The two principal differences between the teams were their discipline and their knowledge of the process. Discipline, that comes from within. But knowledge, ah, well there I can help. Red Gate is bringing a series of free instructional events to the United States in a few weeks time focused primarily on SQL Server (click here right now to register while there’s still space). We’re also offering some .NET instruction too. That’s a full day, free, with top experts in the business. But, the next day, there’s a full day session introducing Agile. You can go to this and learn how to do Agile. Develop that knowledge that will enable you to successfully use the Agile process. Go to this web site to check it out. No, this event is not free, but not everything can be. And it’s not just for developers. DBAs, you need to learn this stuff too. Management could also benefit from understanding these processes (because you guys can help to enforce discipline). It’s really for everyone involved in the development process.

• Application stuck in TCP retransmit

  - by SandeepJ

  I am running Linux kernel 3.13 (Ubuntu 14.04) on two Virtual Machines each of which operates inside two different servers running ESXi 5.1. There is a zeromq client-server application running between the two VMs. After running for about 10-30 minutes, this application consistently hangs due to inability to retransmit a lost packet. When I run the same setup over Ubuntu 12.04 (Linux 3.11), the application never fails If you notice below, "ss" (socket statistics) shows 1 packet lost, sk_wmem_queued of 14110 (i.e. w14110) and a high rto (120000). State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 12350 192.168.2.122:41808 192.168.2.172:55550 timer:(on,16sec,10) uid:1000 ino:35042 sk:ffff880035bcb100 <- skmem:(r0,rb648720,t0,tb1164800,f2274,w14110,o0,bl0) ts sack cubic wscale:7,7 rto:120000 rtt:7.5/3 ato:40 mss:8948 cwnd:1 ssthresh:21 send 9.5Mbps unacked:1 retrans:1/10 lost:1 rcv_rtt:1476 rcv_space:37621 Since this has happened so consistently, I was able to capture the TCP log in wireshark. I found that the packet which is lost does get retransmitted and even acknowledged by the TCP in the other OS (the sequence number is seen in the ACK), but the sender doesn't seem to understand this ACK and continues retransmitting. MTU is 9000 on both virtual machines and througout the route. The packets being sent are large in size. As I said earlier, this does not happen on Ubuntu 12.04 (kernel 3.11). So I did a diff on the TCP config options (seen via "sysctl -a |grep tcp ") between 14.04 and 12.04 and found the following differences. I also noticed that net.ipv4.tcp_mtu_probing=0 in both configurations. Left side is 3.11, right side is 3.13 <<net.ipv4.tcp_abc = 0 <<net.ipv4.tcp_cookie_size = 0 <<net.ipv4.tcp_dma_copybreak = 4096 14c11 << net.ipv4.tcp_early_retrans = 2 --- >> net.ipv4.tcp_early_retrans = 3 17c14 << net.ipv4.tcp_fastopen = 0 >> net.ipv4.tcp_fastopen = 1 20d16 << net.ipv4.tcp_frto_response = 0 26,27c22 << net.ipv4.tcp_max_orphans = 16384 << net.ipv4.tcp_max_ssthresh = 0 >> net.ipv4.tcp_max_orphans = 4096 29,30c24,25 << net.ipv4.tcp_max_tw_buckets = 16384 << net.ipv4.tcp_mem = 94377 125837 188754 >> net.ipv4.tcp_max_tw_buckets = 4096 >> net.ipv4.tcp_mem = 23352 31138 46704 34a30 >> net.ipv4.tcp_notsent_lowat = -1 My question to the networking experts on this forum : Are there any other debugging tools or options I can install/enable to dig further into why this TCP retransmit failure is occurring so consistently ? Are there any configuration changes which might account for this weird behaviour.

• SD Card reader not working on Sony Vaio

  - by TessellatingHeckler

  This laptop (Sony Vaio VGN-Z31MN/B PCG-6z2m) has been installed with Windows 7 64 bit, all the drivers from Sony's VAIO site are installed, and everything in Device Manager both (a) has a driver and (b) shows as working, no exclamation marks or warnings. "Hide empty drives" in Folder options is disabled so the card reader appears, but will not read the card ("please insert a disk in drive O:"). Previously, when the laptop had Windows XP on it, it could read the same card. Also, Windows update suggested driver ("SD Card Reader") doesn't work, Ricoh own drivers install properly but do the same behaviour. Other 3rd party driver suggestions from forums (Acer and Texas-Instruments FlashMedia) do not seem to install properly. I would post the PCI id if I had it, but it was just showing up as rimsptsk\diskricohmemorystickstorage (while it had the Ricoh Driver installed). Edit: If there are any lower level diagnostic utlities which might shed more light on it I'd welcome hearing of them. Anything which might show get it to put troubleshooting logs in the event log or identify chipsets or whatever...

• AWS Cloud Formation.Requires capabilities : [CAPABILITY_IAM] (Child Stack)

  - by Drew Khoury

  I'm running a CloudFormation template in the AWS Console. Running Stack Directly I started with a template that used IAM resources, and the console prompts me to acknowledge IAM capabilities when running the stack directly. Running Stack as a child I then tried to call the same stack from a parent stack and did not receive the same prompt. The stack then failed with the message: Requires capabilities : [CAPABILITY_IAM] Research The docs indicate that I can run CF scripts in a number of ways. There's plenty of docs around CLI/API and supplying the capability parameter, but there appears to be no information about how to make sure it's applied when running through the console. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html IAM Resources in AWS CloudFormation Templates CF Console CLI API What I've done / What I think I've raised an issue via the forum for now, but no response (yet): https://forums.aws.amazon.com/thread.jspa?threadID=139160 I suspect this is a bug in the Console, as there doesn't appear to be any documentation of how to change the behaviour via the console and as far as I'm aware this should just work. Anyone came across the same problem, or can report that it's working fine for them?

• Occasional disk I/O errors in SQLite

  - by Alix Axel

  I have a very simple website running PHP and SQLite 3.7.9 (with PDO). After establishing the SQLite connection I immediately execute the following queries: PRAGMA busy_timeout=0; PRAGMA cache_size=8192; PRAGMA foreign_keys=ON; PRAGMA journal_size_limit=67110000; PRAGMA legacy_file_format=OFF; PRAGMA page_size=4096; PRAGMA recursive_triggers=ON; PRAGMA secure_delete=ON; PRAGMA synchronous=NORMAL; PRAGMA temp_store=MEMORY; PRAGMA journal_mode=WAL; PRAGMA wal_autocheckpoint=4096; This website only has one writer and a few occasional readers, so I don't expect any concurrency problems (and I'm even using WAL). Every couple of days, I've seen this error being reported by PHP: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 10 disk I/O error' in ... Stack trace: #0 ...: PDO-exec('PRAGMA cache_si...') There are several things that make this error very weird to me: it's not a transient problem - no matter how many times I refresh the page, it won't go away the database file is not corrupted - the sqlite3 executable can open the database without problems If the following pragmas are commented out, PHP stops throwing the disk I/O exception: PRAGMA cache_size=8192; PRAGMA synchronous=NORMAL; PRAGMA journal_mode=WAL; Then, after successfully reconnecting to the database, I'm able to reintroduce these pragmas and the code with run smoothly for days - until eventually, the same error will occur without any apparent reason. I wasn't able to reproduce this error so far, so I'm clueless about the origin of it. I'm really curious what may be causing this problem... Any ideas? Environment: Ubuntu Server 12.04 LTS PHP 5.4.15 SQLite 3.7.9 Database size: ? 10MiB Transaction (write) size: ? 1KiB EDIT: Might these symptoms have something to do with busy_timeout?

• Linked server problem on SQL Server 2005

  - by BradyKelly

  I have a weird issue and I hope someone can steer me in the right direction for resolving this please. When I execute the following query against a linked server, I get the following error. I can connect to the server in SSMS as a separate server, and execute a similar query against its Deposits table. The nn.nn is my own replacement to avoid broadcasting our server addresses. The query: select td.Batch , td.DateTimeDeposited from Deposits cd left join [172.nn.nn.32\sqlexpress].Terminal.dbo.Deposits td on cd.DateTimeDeposited = td.DateTimeDeposited The error: OLE DB provider "SQLNCLI" for linked server "172.nn.nn.11\sqlexpress" returned message "Login timeout expired". OLE DB provider "SQLNCLI" for linked server "172.nn.nn.11\sqlexpress" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.". Msg 65535, Level 16, State 1, Line 0 SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. Notice how the error is about server 172.nn.nn.11 and not 172.nn.nn.32. SOLVED (STUPID ME): Somebody had added an extra bit to my query that was scrolled off-screen and was querying the 17.nn.nn.11 server.

• MultiView 2000 terminal emulator not printing correctly to Generic/Text Printer on Windows 7

  - by FantaFan

  Guys & gals, Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck.

• SBS 2008 BPA Warnings After Migration From SBS 2003

  - by Nicholas Piasecki

  We just finished a we-know-just-enough-to-be-dangerous migration from SBS 2003 to SBS 2008, and things seem to have gone relatively smoothly. After running the SBS 2008 Best Practices Analyzer on the destination server, we've got three warning messages, and I can't tell if they're important or not. First, the easy one: SMTP Port (TCP 25 Status): The Edgetransport.exe process should listen on SMTP port 25, but that port is owned by the process. I don't think that this one is a big deal--e-mail is flowing through the SMTP connector. Since there are two spaces between "the" and "process," I'm assuming that for some reason BPA just couldn't figure out the owning process name and this is just some sloppy programming when displaying the message. (Indeed, on subsequent runs of the BPA this message goes away, and other times it comes back.) Now, two more scary sounding ones: No DNS name server records: There are no DNS name server (NS) resource records in the _msdcs sub-domain in the forward lookup zone for Windows SBS 2008. and, similarly, No DNS name server records: There are no DNS name server (NS) resource records in the _msdcs zone for Windows SBS 2008. Now for these two, everything appears to be functioning correctly--but I'm assuming this is a weird state as a result of the SBS 2003 to 2008 migration. Can anyone provide any pointers on how to fix it, or whether or not it can be safely ignored? Thanks!

• Generic/Text Printer on Windows 7 not prompting for file name

  - by FantaFan

  Guys & gals, Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix?

• IIS 7.5, Multiple Application Pools, and URL Rewriting (403.18 -- Forbidden)

  - by Jerry Hewett

  Is there any way to configure IIS 7.5 to perform URL rewrites to different application pools on the same site without running into a 403.18 error? We're using Helicon ISAPI Rewrite 3 on IIS 6 and it's working like a charm. The root-level "application" is running under it's own application pool, and on IIS 6 we have no problems doing URL rewrites from that application pool to any one of the other four application pools. But when I copy the same server configuration information over to IIS 7.5 the URL rewrites to any of the other application pools fail with a "403.18 -- Forbidden" error. The weird bit is that the IIS 6 is not (at least as far as I can tell, by looking at the site Service configuration dialog) running under IIS 5 emulation mode, so somehow the rewrites aren't throwing 403.18 errors. So something must be different... but whatever it is, I sure haven't been able to figure it out. Btw, we're not married to Helicon ISAPI Rewrite. If there's another way to preserve our current rewrite configuration rules using another module or method I'd be more than happy to use it.

• Server 2008 RAID5 resynching

  - by benpage

  I built a W2K8 R2 server last weekend, and built a R5 array using Disk Management, 5x 1TB drives. For the next 60 hours the status said 'Resynching (X%)' as it built the array. during this time i did read and write to the drive (slowly) and once the rebuild was complete speeds were quite fast. I was copying over some data from a USB hard drive overnight, and the machine crashed (looking in the error i believe it was the driver for the usb drive) and so the RAID5 went back to resynching, since the machine was not shut down properly. The issue is, it's been about 48 hours since that started and I'm happy to say it will take roughly 60 hours again to resynch, however.. all this time in Disk Management, the status has only said 'Resynching', not 'Resynching (X%)'. The hard drive light is going nuts, and read/writes are slow again, so I'm assuming it is actually resynching. The question is - is that a correct assumption? and why is disk management not telling me what %age it's done? Is this normal behaviour for a not-properly-shut-down r5 array?

• Howto make a diff of a bios or backup/ restore all bios settings

  - by sfonck

  Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

• Telnet does not give a response

  - by floorish

  Some wireless access points are acting a little weird, so I want to reboot them every couple of hours. Luckily there exists a security flaw which lets me login as root through telnet when using port 1111 (without username and password). Now I want to use that to let my QNAP NAS execute the reboot command through telnet every now and then. The problem is however that that telnet version doesn't give any response if I connect to the AP. The telnet I use on OSX works just fine but the one on the NAS not. BusyBox v1.01 (2012.06.14-18:35+0000) multi-call binary Usage: telnet [-a] [-l USER] HOST [PORT] When I execute telnet <HOST> 1111 nothing happens. I can send the escape character ^] which gives me the following options: Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet The only way to get some commands executed is by suspending telnet with z followed by some random command which isn't recognized. Then the prompt shows this: # telnet 192.168.1.5 1111 ^] Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet z continuing... asdf Illegal command. 00> After that I am able to communicate with the AP, but when I exit the telnet session and try the same again, the AP refuses to connect at all and it must be manually rebooted (looks like the telnet session isn't shut down properly on the AP). So the question is what commands should I execute in order to communicate with the AP using the Busybox telnet version of the QNAP? (No, can't use ssh unfortunately)

• fedora12, yum not releasing "lock" after performing an action

  - by James.Elsey

  Hello, This problem has been occurring quite frequently recently and I can't seem to find a way of preventing it. Whenever I perform an action with yum such as to install or remove software, it appears to execute successfully but then I'm unable to move onto the next yum command For example, I executed yum remove skype, it appeared to remove ok, but next when I try to yum search skype it appears that yum is still processing, and I have to manually kill that process via kill 1234 (or whatever the PID is) My output is as follows [root@nevada james]# yum remove skype Loaded plugins: presto, refresh-packagekit Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package skype.i586 0:2.1.0.47-fc10 set to be erased --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Removing: skype i586 2.1.0.47-fc10 installed 24 M Transaction Summary ================================================================================ Remove 1 Package(s) Reinstall 0 Package(s) Downgrade 0 Package(s) Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Erasing : skype-2.1.0.47-fc10.i586 1/1 Removed: skype.i586 0:2.1.0.47-fc10 Complete!

• Postfix: LDAP not working (warning: dict_ldap_lookup: Search base not found: 32: No such object)

  - by Heinzi

  I set up LDAP access with postfix. ldapsearch -D "cn=postfix,ou=users,ou=system,[domain]" -w postfix -b "ou=users,ou=people,[domain]" -s sub "(&(objectclass=inetOrgPerson)(mail=[mailaddr]))" delivers the correct entry. The LDAP config file looks like root@server2:/etc/postfix/ldap# cat mailbox_maps.cf server_host = localhost search_base = ou=users,ou=people,[domain] scope = sub bind = yes bind_dn = cn=postfix,ou=users,ou=system,[domain] bind_pw = postfix query_filter = (&(objectclass=inetOrgPerson)(mail=%s)) result_attribute = uid debug_level = 2 The bind_dn and bind_pw should be the same as I used above with ldapsearch. Nevertheless, calling postmap doesn't work: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf postmap: warning: dict_ldap_lookup: /etc/postfix/ldap/mailbox_maps.cf: Search base 'ou=users,ou=people,[domain]' not found: 32: No such object If I change LDAP configuration, so that anonymous users have complete access to LDAP olcAccess: {-1}to * by * read then it works: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf [user-id] But when I restrict this access to the postfix user: olcAccess: {-1}to * by dn="cn=postfix,ou=users,ou=system,[domain]" read by * break it doesn't work but produces the error printed above (although ldapsearch works, only postmap doesn't). Why doesn't it work when binding with a postfix DN? I think I set up the LDAP ACL for the postfix user correctly, as the ldapsearch command should prove. What can be the reason for this behaviour?

• Programmable Home Security Alarm [closed]

  - by stej

  I don't ask for recommendation! (just wanted to say that; anyway it doesn't matter now as the question is closed) I've seen some advertisements about home alarms that notifies me that something is happening in my house. None of them mentioned programmability (with real programming language like e.g C, assembler, whatever). As a programmer I'd like to have a possibility to add some behaviour, that is not part of the alarm itself. This might be: take snapshots of all cameras in a house and send it to some email send email, twitter message, skype message to some predefined account send email to a police (silly, I know) start turning the lights on and off (scary, right?) etc. (would be veeery challenging with assembler, I know; but lets suppose I can use some more high level language) I don't expect that there is a alarm system capable of this stuff, that's why I'm looking for a programmable module. Question: Is it even possible? Is it good idea (my program could crash and cause instability of the system).

• Couldn't upload files to Sharepoint site while passing through Squid Proxy

  - by Ecio

  Hi all, we have this issue: one of our employees is collaborating with a supplier and he needs to upload documents on a Sharepoint site hosted on the supplier's main site. In our environment we use Squid Proxy to allow people navigate on the net (we have NTLM authentication and users transparently authenticate while using IE and FF). It seems that this specific Sharepoint site is using Integrated Windows Authentication only, and according to some research on the net it seems that this can have troubles with proxies. More specifically, we have tried two Squid versions: with Squid 3.0 we are unable to login to the site (the browser loads an empty page) with Squid 2.7 (that supports "Connection Pinning") we are able to login into the site, move on the different sections BUT.. when we try to upload a file that is bigger than a couple of KiloBytes (i.e. 10KB) the browser loads an error page (i think it's a 401 unauthorized but i must verify it) we've tried changing a couple of Squid options (in 2.7), what we got is that when you try to upload the file you got an authentication box (just like the initial login) and it refuses to go on even if you enter the same authentication credentials. What's really strange is that when you try to upload a small file (i.e. a text or binary 1KB file) the upload succeeds. I initially thought that maybe there was something misconfigured on their Sharepoint site but I've tried also this site: www.xsolive.com (it's a sharepoint 2007 demo site) and I've experienced the same problem. Has any of you experienced such behaviour? Thanks! Of course we've suggested to the supplier to activate also Basic+SSL and we're waiting for their reply..
