  • Apache2 + Php + Pthreads HowTos

    - by Drug
    04 LTS 64 bit. What I would really love to do is sudo apt-get install libapache2-mod-php5 but compile PHP with --enable-maintainer-zts so I could later install pthreads with pecl install pthreads. Sadly I understand that it is not possible. I know that the easiest way is to recompile PHP together with apache support and zts. However I really like the way the standard Ubuntu PHP package is configured and I am used to the path`s for CLI php.ini config, Apache php.ini config and other paths for modules and files that this Ubuntu package defines. So i just want to change the package source a little bit and install it. # Get the stuff necessary to build the package sudo apt-get build-dep php5-common # Get the package source sudo apt-get source php5-common At this point I am getting sources not for the php5-common package but the whole php5 package. If I would sudo make && make install at this point, would it mean that I am installing a lot of unnecessary stuff? # Add configuration options ./configure --enable-maintainer-zts Does this mean that I am appending a configuration option? Or am I generating a whole new config? Alternative at this point Is there a way of getting the config options that this package defines, so that I can grab a php source from php.net and compile it with $ ./configure --prefix=package_prefix \ // Option 1 from package --enable-embed \ // Option 2 from package --with-regex=php \ // Option 3 from package Continuing the main idea ... Solution 1 # Compile (Not compiling) sudo make && make install Will I be building PHP with EVERYTHING at this point? If I compile like this, I will not be able to remove the mess I made using sudo apt-get purge php5? Solution 2 # ReCompile the package dpkg-buildpackage -rfakeroot -uc -b This does not compile also. Please correct my steps, so I can install everything correctly.

  • MS Word reports files read-only on Win Server 2003 file server

    - by Larry Hamelin
    I'm not a sysadmin, but I play one on TV: I'm trying to fix a problem for my mom's tiny non-profit company's server. I set up a Windows Server 2003 machine as a domain controller and file server. Everything has been working well for a few months, but lately when she tries to save changes to a Word (Office XP) document stored on the server, Word will intermittently report that the file is read-only. Saving to an alternate file in the same directory works, and when she closes Word and re-opens the original document, it'll save changes just fine. No one else ever has these files open. I've checked security and share permissions, and everything's OK. We've tried rebooting the server, but the problem continues, but intermittently. I have no clue what's going on. Help!

  • Problems with Adobe Flash

    - by Georg Scholz
    I'm running Windows 7, 64-Bit on a Core-i5 HP Notebook. For approximately the last 3 months, I've had major problems with Adobe Flash. Flash has been uninstalled and installed again multiple times. No changes. Here is what happens in different browsers: (All browsers are in the latest version as of this post) Firefox: Doesn't work at all. This bothers me most, since FF is my favorite browser; I'm using a lot of Plugins. Have tried to de-activate all Plugins, but no change. IE and Chrome: Works, but most pages with Flash are stuck during page load for ~30 seconds. After that, everything is fine. Opera: No problems, everything working as it should. Strange, eh? Any help is highly appreciated!

  • DNS Provider/Domain Registrar

    - by Arcath
    I have a whole bunch of domains with my current web host and when i got the package i got it with a few gig of web space and a bunch of mysql databases but times have changed and now and i don't use the hosting im paying for, and i just my host as a DNS server to forward everything else where. The process of removing the host is going to require me to transfer all the domains to another package etc... which is going to cause disruption so my question is: Who is the best provider for DNS only? I don't want any space or mail just someone to hold the domains and let me set any DNS options I want (A/MX/CNAME records for everything, even possibly the ability to point my domains at my own DNS server).

  • Apple iOS Apps and caching at the edge proxy

    - by Matthew Iselin
    Our network contains a growing number of iOS devices, all of which with very similar configurations. All Internet access is via a transparent proxy. We've found that iOS updates and some free apps cache fine on the proxy, but any paid apps fail to cache properly (as they seem to be encrypted to the Apple ID (?)). I'm just wondering if there's any way forward with this where we could cache the paid apps so that they are purchased n times, but downloaded from the proxy cache instead of from the Internet each time. Bandwidth caps aside, the download direct from the Internet slows everything down for everyone, regardless of fairness queueing and related 'fixes'. I know this is quite unlikely, but I figured there's nothing to lose and everything to gain before I look into other solutions (eg, QoS).

  • new project; entire node.js app

    - by Jared
    I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that? I was asked to re post this somewhere else as it was not up to the format for SO, OP from here http://stackoverflow.com/questions/12649469/new-project-need-some-start-up-advice-node-js-app#comment17062924_12649469

  • Problem to connect to MySQL server (error #2002) in PHP

    - by user41514
    Hello, I installed ZWAMP 1.0.7 (on Windows 7), but I'm having a weird problem. I can't connect to my MySQL server from any PHP script. If I try to use MySQL command line everything works fine but PHPMyAdmin retruns error #2002. I'm not sure whether it's important or not but MySQL server is not able to create socket file. I don't know what's the problem but I think everything is configured in my.cnf properly. Do you have any ideas?

  • Cannot seem to disable ability to view temporary internet files via group policy

    - by user162707
    Windows XP Pro SP3, IE8 (8.0.6001.18702), within local gpedit.msc I did the below: User Config/Admin Temp/Windows Comp/IE enabled: disable changing temporary internet file settings User Config/Admin Temp/Windows Comp/IE/Delete Browsing History enabled all (11 items) However there is a loophole that lets me still wipe history & other files via: Tools, Internet Options, Browsing History, Settings, View Objects, delete everything, hit up arrow, go to History (hidden folders has to be on), delete everything Only way around this I can see is to disable General Internet Options Page via group policy, setup NTFS folder restrictions on that temp internet files (worried about adverse affects like not being able to store them), or further grind-down group policy somewhere else to prevent deleting files. Just odd group policy wouldn't have a settings to simply disable the Browser History Settings button (as it further shows the location which a user could just go to). So just curious if someone can confirm maybe this is simply not available in group policy & their suggested action

  • Munin does not show Apache/mySQL stats in web view

    - by Chris
    I'm facing a very strange Problem. I just set up Munin on a fresh Ubuntu slice with a common LAMP Stack. Everything works great, except that Munin does just not show the Apache/mySQL stats in the web view. Everything else in the web view works great, Apache works, mySQL works. I even tried calling the plugins via console: sudo munin-run apache_accesses And it works fine. AFAIK Munin log files are not telling me any problems.. My only hint: when I run munin-run without sudo it gives me a "Permission denied" - could this be the problem?

  • How broad should a computer science/engineering student go?

    - by AskQuestions
    I have less than 2 years of college left and I still don't know what to focus on. But this is not about me, this is about being a future developer. I realize that questions like "Which language should I learn next?" are not really popular, but I think my question is broader than that. I often see people write things like "You have to learn many different things. Being a developer is not about learning one programming language / technology and then doing that for the rest of your life". Well, sure, but it's impossible to really learn everything thoroughly. Does that mean that one should just learn the basics of everything and then learn some things more thoroughly AFTER getting a particular job? I mean, the best way to learn programming is by actually programming stuff... But projects take time. Does an average developer really switch between (for example) being a web developer, doing artificial intelligence and machine learning related stuff and programming close to the hardware? I mean, I know a lot of different things, but I don't feel proficient in any of those things. If I want to find a job as a web developer (that's just an example) after I finish college, shouldn't I do some web related project (maybe using something I still don't know) rather than try to learn functional programming? So, the question is: How broad should a computer science student's field of focus be? One programming language is surely far too narrow, but what is too broad?

  • What is the official installer for Unix packages on Mac OS?

    - by dehmann
    I'm a bit confused about the installation of standard Unix packages on Mac OS X. For example, I have /usr/bin/svn, which is SVN v.1.4.4, but FinkCommander says svn is not installed. The same holds for other packages, like emacs etc. Is that just a wrong FinkCommander setting? Currently it is set to install everything in /sw, which is not even in the PATH. So, do I just have to set it to install packages to /usr, and it will recognize the installed software? I don't want to install duplicate packages of everything, and it is quite weird that the FinkCommander seems not to be in sync with the installed software. Or is there any other installer I should be using? Is Mac Ports the recommended installer to use? (I'm using Mac OS 10.5.8.)

  • How do you keep cool when production system goes down?

    - by Mag20
    This has happened to most of us... You come to work one day. Everything seems normal: the sun is shining, birds are chirping, but you notice a couple of weird things on your way to work like deja vu with cat in matrix. You get into office, there are a lot of phones ringing, but could be that they are just doing a new sales promotion. You settle in, when you notice a dark cloud hovering over you. It takes you a couple of moments, but you recognize the cloud is your boss. Usually he checks on you every morning with his "Soooo Peeeeter, how about those TCP/IP reports?" routine, but today he forgot everything about common manners and rudely invaded your personal space. No "Good Morning", just some drooling, grunts and curses. He reminds you a bit of neanderthal who is trying to get away from cyber tooth tiger, fear and panic all compressed in a tight ball. You try to decipher the new language that he created since yesterday and you start understanding that something bad happened overnight - production system went down. Now, your system is usually used by clients during regular working hours from 9-5, but for whatever reason you didn't get any alerts on your beeper (for people under 30 - beeper was like a mobile phone that could only ring and tell you who beeped you). Need to remember to charge it next time. So it is 8:45am, the system MUST be up at 9am. Every 10 seconds, your boss lets out yet another curse which communicates to you that another customer is having problems getting into the system. Also several account managers are now hovering over your boss trying to make him understand how clients are REALLY REALLY suffering. Everyone is depending on you to get the system up ASAP and at the same time hinder your progress by constantly distracting you. How do you keep cool in a situation like this?

  • Animating DOM elements vs refreshing a single Canvas

    - by mgibsonbr
    A few years ago, when the HTML Canvas element was still kinda fresh, I wrote a small game in a rather "unusual" way: each game element had its own canvas, and frequently animated elements even had multiple canvases, one for each animation sprite. This way, the translation would be done by manipulating the DOM position of the canvases, while the sprite animation would consist of altering the visibility of the already drawn canvases. (z-indexes, of course, were the tricky part) It worked like a charm: even in IE6 with excanvas it showed a decent performance, and everything was rather consistent between browsers, including some smartphones. Now I'm thinking in writing a larger game engine in the same fashion, so I'm wondering whether it would be a good idea to do so in the current context (with all the advances in browsers and so on). I know I'm trading memory for time, so this needs to be customizable (even at runtime) for each machine the game will be running. But I believe using separate canvases would also help to avoid the game "freezing" on CPU spikes, since the translation would still happen even if the redraws lag for a while. Besides, the browsers' rendering engines are already optimized in may ways, so I'm guessing this scheme would also reduce the load on the CPU (in contrast to doing everything in JavaScript - specially the less optimized ones). It looks good in my head, but I'd like to hear the opinion of more experienced people before proceeding further. Is there any known drawback of doing this? I'm particulartly unexperienced in dealing with the GPU, so I wonder whether this "trick" would nullify any benefit of using a single, big canvas. Or maybe on modern devices it's overkill (though I'm skeptic about the claims that canvas+js - especially WebGL - will ever be a good alternative to native code). Any thoughts?

  • Auto-mount filesystems on boot fails (12.10)

    - by Joshua Pruitt
    I have a Compaq HP 8200 slim desktop running 12.10 with encrypted partitions (set up with the text-based installer). Everything's working fine, except... When I boot the computer, my /boot and /boot/efi directories refuse to mount automatically. I'm dropped to the root console, where I must enter 'mountall -v', and everything then continues on just fine. This was happening under 12.04. I've recently upgraded to 12.10, and the problem persists. Except now, in addition to /boot and /boot/efi not mounting, roughly 50% of the time /var will not be auto-mounted as well (and again, 'mountall -v' fixes allows me to boot and move on). I'm puzzled about this one. Running 'fsck' doesn't seem to do anything (the filesystems aren't damaged anyway). What can I try to solve this issue? Here's my /etc/fstab: http://paste.ubuntu.com/1338508/ Thanks in advance!!! Addendum: I have tried changing the entries in fstab from UUIDs to the actual devices, to no avail.

  • Problem Installing Xubuntu 12.04 Audio-Video codecs

    - by Seib
    I used Crouton to install Xubuntu 12.04.4 LTS with the XFCE environment on my HP Chromebook 11. I've gotten it all fully installed and everything; the only thing I'm doing now is the basic setup things, like adding codecs and other things like LibreOffice, VLC, Firefox, Ubuntu Software Center, etc. This information I got from 2 sources: http://www.efytimes.com/e1/fullnews.asp?edid=137269 http://www.binarytides.com/better-xubuntu-14-04/ . I'm currently on the same step at both URLs, which is #6 on Link 1 and #8 on Link 2. Per the articles, which both said the same thing, I typed in sudo apt-get install xubuntu-restricted-extras libavcodec-extra and it didn't do anything. It just kept on saying the same thing: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libavcodec-extra I've spend the last hour or so scouring the internet for a solution, for a hint even at what is going on. I don't want to do a clean reinstall, for two reasons: 1) it's takes like 1.5h just to get the croot fully installed, and 2) everything but this out of what I've done so far (up to #6 at Link 1 & up to #8 at Link 2) works except the audio. I've already installed flash, so YouTube works fine. It's just I can't hear any audio. Please help? Thanks in advance. I appreciate all the great help I've been getting from AskUbuntu lately. You all are great.

  • Coarse Collision Detection in highly dynamic environment

    - by Millianz
    I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

  • Grepping grep output fails

    - by viraptor
    I'm trying to grep the output of ngrep. Unfortunately when I add another grep to the pipeline, I get no output at all. It can be some other command too - cat / grep / tee - everything breaks the chain. Example: # this works: $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' -- U +1.469535 xxx:5060 -> xxx:5060 SIP/2.0 180 Ringing. -- U +0.001384 xxx:5060 -> xxx:2048 SIP/2.0 180 Ringing. but #these don't: $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | egrep '^U' $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | cat $ ngrep -l -q -T -Wbyline -d any udp and port 5060 | egrep -B1 '^SIP/2.0 180' | tee test If I use cat somefile instead of ngrep at the start, everything works as expected. Any ideas what could go wrong here?

  • PCI compliance when using third-party processing

    - by Moses
    My company is outsourcing the development of our new e-commerce site to a third party web development company. The way they set up our site to handle transactions is by having the user enter the necessary payment info, then passing that data to a third party merchant that processes the payment, then completing the transaction if everything is good. When the issue of PCI/DSS compliance was raised, they said: You wont need PCI certification because the clients browser will send the sensitive information directly to the third party merchant when the transaction is processed. However, the process will be transparent to the user because all interface and displays are controlled by us. The only server required to be compliant is the third party merchant's because no sensitive card data ever touches your server or web app. Even though I very much so trust and respect the knowledge of our web developers, what they are saying is raising some serious red flags for me. The way the site is described, I am sure we will not be using a hosted payment page like PayPal or Google Checkout offers (how could we maintain control over UI if we were?) And while my knowledge of e-commerce is laughable at best, it seems like the only other option for us would be to use XML direct to communicate with our third party merchant for processing. My two questions are as follows: Based off everything you've read, is "XML Direct" the only option they could conceivably be using, or is there another method I don't know of which they could be implementing? Most importantly, is it true our site does not need PCI certification? As I understand it, using the XML direct method means that we do have to be PCI/DSS certified, and the only way around getting certified is through a payment hosted page (i.e. PayPal).

  • Odd Android touch event problem

    - by user22241
    Overview When testing my game I came across a bizarre problem with my touch controls. Note this isn't related to multi-touch as I completely removed my ACTION_POINTER_UP and ACTION_POINTER_DOWN along with my ACTION_MOVE code. So I'm simply working with ACTION_UP and ACTION_DOWN now and still get the problem. The problem I have a left and right button on the left of the screen and a jump button on the right. Everything works as it should but if I touch a large area of my hand (the fleshy part at the base of the thumb for instance) onto the screen, then release it and then press one of my arrows, the sprite moves in that direction for a few seconds, and then ACTION_UP is mysteriously triggered. The sprite stops and then if I release my finger and re-apply it to an arrow, the same thing happens. This goes on and on and eventually (randomly??) stops and everything work OK again. Test device & OS Google Nexus 10 Tablet running Jellybean 4.2.2 Code //Action upon which to switch actionMask = event.getActionMasked(); //Pointer Index of the currently touching pointer pointerIndex = event.getActionIndex(); //Number of pointers (for multi-touch) pointerCount = event.getPointerCount(); //ID of the pointer currently being processed (Multitouch) pointerID = event.getPointerId(pointerIndex); switch (actionMask){ //Primary pointer down case MotionEvent.ACTION_DOWN: { //if pressing left button then set moving left if (isLeftPressed(event.getX(), event.getY())){ renderer.setSpriteLeft(); } //if pressing right button then set moving right else if (isRightPressed(event.getX(), event.getY())){ renderer.setSpriteRight(); } //if pressing jump button then set sprite jumping else if (isJumpPressed(event.getX(),event.getY())){ renderer.setSpriteState('j', true); } break; }//End of case //Primary pointer up case MotionEvent.ACTION_UP:{ //When finger leaves the screen, stop sprite's horizontal movement renderer.setSpriteStopped(); break; }

  • How does one escape the GPL?

    - by tehtros
    DISCLAIMER I don't pretend to know anything about licensing. In fact, everything I say below may be completely false! Backstory: Recently, I've been looking for a decent game engine, and I think I've found one that I really like, Cafu Engine. However, they have a dual licensing plan, where everything you make with the engine is forced under GPL, unless you pay for a commercial license. I'm not saying that it's a bad engine, they even say that they are very relaxed about the licensing fees. However, the fact that it even involves the GPL scares me. So my question is basicly, how does one escape the GPL. Here's an example: The id Tech engine, also known as the Quake engine, or the Doom engine, was the base for the popular Source engine. However, the id Tech engine has been released under the GPL, and the Source engine is proprietary. Did Valve get a different license? Or did they do something to escape the GPL? Is there a way to escape the GPL? Or, if you use GPL'd source code as a base for another project, are you forced to use the GPL, and make your source code available to the world. Could some random person take the id Tech engine, modify it past the point of recognition, then use it as a proprietary engine for commercial products? Or are they required to make it open source. One last thing, I generally have no problem what-so-ever with open source. However I feel that open source has it's place, but that is not in the bushiness world.

  • In an Entity/Component system, can component data be implemented as a simple array of key-value pairs? [on hold]

    - by 010110110101
    I'm trying to wrap my head around how to organize components in an Entity Component Systems once everything in the current scene/level is loaded in memory. (I'm a hobbyist BTW) Some people seem to implement the Entity as an object that contains a list of of "Component" objects. Components contain data organized as an array of key-value pairs. Where the value is serialized "somehow". (pseudocode is loosely in C# for brevity) class Entity { Guid _id; List<Component> _components; } class Component { List<ComponentAttributeValue> _attributes; } class ComponentAttributeValue { string AttributeName; object AttributeValue; } Others describe Components as an in-memory "table". An entity acquires the component by having its key placed in a table. The attributes of the component-entity instance are like the columns in a table class Renderable_Component { List<RenderableComponentAttributeValue> _entities; } class RenderableComponentAttributeValue { Guid entityId; matrix4 transformation; // other stuff for rendering // everything is strongly typed } Others describe this actually as a table. (and such tables sound like an EAV database schema BTW) (and the value is serialized "somehow") Render_Component_Table ---------------- Entity Id Attribute Name Attribute Value and when brought into running code: class Entity { Guid _id; Dictionary<string, object> _attributes; } My specific question is: Given various components, (Renderable, Positionable, Explodeable, Hideable, etc) and given that each component has an attribute with a particular name, (TRANSLATION_MATRIX, PARTICLE_EMISSION_VELOCITY, CAN_HIDE, FAVORITE_COLOR, etc) should: an entity contain a list of components where each component, in turn, has their own array of named attributes with values serialized somehow or should components exist as in-memory tables of entity references and associated with each "row" there are "columns" representing the attribute with values that are specific to each entity instance and are strongly typed or all attributes be stored in an entity as a singular array of named attributes with values serialized somehow (could have name collisions) or something else???

  • Finding a way to simplify complex queries on legacy application

    - by glenatron
    I am working with an existing application built on Rails 3.1/MySql with much of the work taking place in a JavaScript interface, although the actual platforms are not tremendously relevant here, except in that they give context. The application is powerful, handles a reasonable amount of data and works well. As the number of customers using it and the complexity of the projects they create increases, however, we are starting to run into a few performance problems. As far as I can tell, the source of these problems is that the data represents a tree and it is very hard for ActiveRecord to deterministically know what data it should be retrieving. My model has many relationships like this: Project has_many Nodes has_many GlobalConditions Node has_one Parent has_many Nodes has_many WeightingFactors through NodeFactors has_many Tags through NodeTags GlobalCondition has_many Nodes ( referenced by Id, rather than replicating tree ) WeightingFactor has_many Nodes through NodeFactors Tag has_many Nodes through NodeTags The whole system has something in the region of thirty types which optionally hang off one or many nodes in the tree. My question is: What can I do to retrieve and construct this data faster? Having worked a lot with .Net, if I was in a similar situation there, I would look at building up a Stored Procedure to pull everything out of the database in one go but I would prefer to keep my logic in the application and from what I can tell it would be hard to take the queried data and build ActiveRecord objects from it without losing their integrity, which would cause more problems than it solves. It has also occurred to me that I could bunch the data up and send some of it across asynchronously, which would not improve performance but would improve the user perception of performance. However if sections of the data appeared after page load that could also be quite confusing. I am wondering whether it would be a useful strategy to make everything aware of it's parent project, so that one could pull all the records for that project and then build up the relationships later, but given the ubiquity of complex trees in day to day programming life I wouldn't be surprised if there were some better design patterns or standard approaches to this type of situation that I am not well versed in.

  • What ufw allows/denies by default?

    - by mgibsonbr
    I was accessing a server running Ubuntu 12.04 Server using SSH and managed to lock myself out of it. I'm still wondering how that happened: The firewall was enabled by default; sudo ufw status did not show any rules (but I could SSH to the server normally); I tried explicitly allowing ports 80 and 443 using the commands: sudo ufw allow 80 sudo ufw allow 443 sudo ufw status now showed something like: Status: active To Action From -- ------ ---- 80 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere 443 ALLOW Anywhere (v6) (Recalling from memory and seeing some examples; I can't access the server to see the exact output, so I might be mistaken) After logging out of SSH, now I can't log in anymore (connection timeout). What just happened? There were no DENY rules previously (AFAIK), neither I introduced any. How could SSH be previously available and now it's not? Does ufw (or more precisely iptables) allow everything by default, unless you explicitly allow something, then it denies everything by default? Or did I do something wrong, that broke the existing rules somehow?

  • Grub menu will not show the first time I try to boot my ubuntu server 12.04 after it is shutdown for a long time

    - by user211477
    I am running into a booting issue after installing Ubuntu Server 12.04 LTS. Following is the symptom of the problem. SYSTEM DESCRIPTION: Dual core AMD Athlon 64 3 Disks: two SATA (out of which one is SSD) and one PATA. Using LVM for disk partition management. /boot is not under LVM rest of the partitions are. / is on the SSD BIOS boot sequence is correct and points to the disk with /boot and boot loader is installed on this disk. SYMPTOMS: POST messages Blinking cursor on first line then moves to second line Screen flickers then becomes black Everything is unresponsive, hard reboot POST messages will not show up on screen. Monitor displays powersave message Force shutdown machine again. Shutoff power to machine for a few minutes. Restart machine. POST message show up. Grub menu shows up Ubuntu server 12.04 boots normally. From now on Ubuntu server boots normally until machine is shutdown for a long time (for example, 30 mins) Repeat steps 1 through 13 once the machine is started after a long time. WHAT DID I TRY? I read several posts and have tried: radeon.modeset=0 setting the gfxmode edd=0 nolacpi boot-repair Nothing seems to work. In my search I did see only one post with this same symptom. Unfortunately, I am not being able to locate that post anymore. The interesting fact is that with this same machine configuration, if I install Ubuntu Desktop 12.04 then everything works fine. Any help will be appreciated.
