• Disk drive for / not ready on boot after upgrade from 10.04 to 12.04

  - by Mathieu M-Gosselin

  After upgrading (using the Upgrade button from the update manager) from 10.04.4 to 12.04.1, I cannot boot anymore. Upon booting, I am greeted with the Ubuntu logo and the error "The disk drive for / is not ready yet or not present". I have the option to wait, to skip and to access a basic shell. Waiting overnight did nothing, skipping just gives me the same error for /tmp, /home, then for a UUID and finally it just goes to a black screen with a white "_" in the top left corner. My setup is a dual boot one with XP on a single hard drive, I use separate partitions for / and /home. Back in the day I installed 8.04 directly from the CD while leaving a partition for XP, which I installed after. This setup had never caused any such issues, even when upgrading from 8.04 to 10.04. I have done plenty of research regarding this issue, as many others seem to have had similar issues after doing the same upgrade as me. However, while for most what fixed the problem was running: apt-get -f install after remounting / in read-write, it didn't do it for me. I got dependency errors (see here), which I also investigated. I found https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740 where most people say the solution that worked is (prior to running the above command) running: apt-get install -o APT::Immediate-Configure=false -f apt python-minimal but that also got me a lot of dependencies errors as output (see here), similar to #34 in the above thread. I also read that running: dpkg --configure -a could help, at first it wouldn't run because it had trouble parsing /var/lib/dpkg/status since there was an extra blank line in a package description (see https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/916799) but I removed it using vim (and then reran the command). It still gives me output that looks like an error, though. Here it is: http://paste.ubuntu.com/1338074/. I also tried re-running the above apt-get commands after that, to no avail. I'm running out of things to try in the hope of getting this fixed, your help would be very much appreciated! Thank you in advance.

• Welcome To The Nashorn Blog

  - by jlaskey

  Welcome to all.  Time to break the ice and instantiate The Nashorn Blog.  I hope to contribute routinely, but we are very busy, at this point, preparing for the next development milestone and, of course, getting ready for open source. So, if there are long gaps between postings please forgive. We're just coming back from JavaOne and are stoked by the positive response to all the Nashorn sessions. It was great for the team to have the front and centre slide from Georges Saab early in the keynote. It seems we have support coming from all directions. Most of the session videos are posted. Check out the links. Nashorn: Optimizing JavaScript and Dynamic Language Execution on the JVM. Unfortunately, Marcus - the code generation juggernaut,  got saddled with the first session of the first day. Still, he had a decent turnout. The talk focused on issues relating to optimizations we did to get good performance from the JVM. Much yet to be done but looking good. Nashorn: JavaScript on the JVM. This was the main talk about Nashorn. I delivered the little bit of this and a little bit of that session with an overview, a follow up on the open source announcement, a run through a few of the Nashorn features and some demos. The room was SRO, about 250±. High points: Sam Pullara, from Twitter, came forward to describe how painless it was to get Mustache.js up and running (20x over Rhino), and,  John Ceccarelli, from NetBeans came forward to describe how Nashorn has become an integral part of Netbeans. A healthy Q & A at the end was very encouraging. Meet the Nashorn JavaScript Team. Michel, Attila, Marcus and myself hosted a Q & A. There was only a handful of people in the room (we assume it was because of a conflicting session ;-) .) Most of the questions centred around Node.jar, which leads me to believe, Nashorn + Node.jar is what has the most interest. Akhil, Mr. Node.jar, sitting in the audience, fielded the Node.jar questions. Nashorn, Node, and Java Persistence. Doug Clarke, Akhil and myself, discussed the title topics, followed by a lengthy Q & A (security had to hustle us out.) 80 or so in the room. Lots of questions about Node.jar. It was great to see Doug's use of Nashorn + JPA. Nashorn in action, with such elegance and grace. Putting the Metaobject Protocol to Work: Nashorn’s Java Bindings. Attila discussed how he applied Dynalink to Nashorn. Good turn out for this session as well. I have a feeling that once people discover and embrace this hidden gem, great things will happen for all languages running on the JVM. Finally, there were quite a few JavaOne sessions that focused on non-Java languages and their impact on the JVM. I've always believed that one's tool belt should carry a variety of programming languages, not just for domain/task applicability, but also to enhance your thinking and approaches to problem solving. For the most part, future blog entries will focus on 'how to' in Nashorn, but if you have any suggestions for topics you want discussed, please drop a line.  Cheers.

• Running Built-In Test Simulator with SOA Suite Healthcare 11g in PS4 and PS5

  - by Shub Lahiri, A-Team

  Background SOA Suite for Healthcare Integration pack comes with a pre-installed simulator that can be used as an external endpoint to generate inbound and outbound HL7 traffic on specified MLLP ports. This is a command-line utility that can be very handy when trying to build a complete end-to-end demo within a standalone, closed environment. The ant-based utility accepts the name of a configuration file as the command-line input argument. The format of this configuration file has changed between PS4 and PS5. In PS4, the configuration file was XML based and in PS5, it is name-value property based. The rest of this note highlights these differences and provides samples that can be used to run the first scenario from the product samples set. PS4 - Configuration File The sample configuration file for PS4 is shown below. The configuration file contains information about the following items: Directory for incoming and outgoing files for the host running SOA Suite Healthcare Polling Interval for the directory External Endpoint Logical Names External Endpoint Server Host Name and Ports Message throughput to be simulated for generating outbound messages Documents to be handled by different endpoints A copy of this file can be downloaded from here. PS5 - Configuration File The corresponding sample configuration file for PS5 is shown below. The configuration file contains similar information about the sample scenario but is not in XML format. It has name-value pairs specified in the form of a properties file. This sample file can be downloaded from here. Simulator Configuration Before running the simulator, the environment has to be set by defining the proper ANT_HOME and JAVA_HOME. The following extract is taken from a working sample shell script to set the environment: Also, as a part of setting the environment, template jndi.properties and logging.properties can be generated by using the following ant command: ant -f ant-b2bsimulator-util.xml b2bsimulator-prop Sample jndi.properties and logging.properties are shown below and can be modified, as needed. The jndi.properties contains information about connectivity to the local Weblogic Managed Server instance and the logging.properties file controls the amount of logging that can be generated from the running simulator process. Simulator Usage - Start and Stop The command syntax to launch the simulator via ant is the same in PS4 and PS5. Only the appropriate configuration file has to be supplied as the command-line argument, for example: ant -f ant-b2bsimulator-util.xml b2bsimulatorstart -Dargs="simulator1.hl7-config.xml" This will start the simulator and will keep running to provide an active external endpoint for SOA Healthcare Integration engine. To stop the simulator, a similar ant command can be used, for example: ant -f ant-b2bsimulator-util.xml b2bsimulatorstop

• Removing occurrences of characters in a string

  - by DmainEvent

  I am reading this book, programming Interviews exposed by John Wiley and sons and in chapter 6 they are discussing removing all instances of characters in a src string using a removal string... so removeChars(string str, string remove) In there writeup they sey the steps to accomplish this are to have a boolean lookup array with all values initially set to false, then loop through each character in remove setting the corresponding value in the lookup array to true (note: this could also be a hash if the possible character set where huge like Unicode-16 or something like that or if str and remove are both relatively small... < 100 characters I suppose). You then iterate through the str with a source and destination index, copying each character only if its corresponding value in the lookup array is false... Which makes sense... I don't understand the code that they use however... They have for(src = 0; src < len; ++src){ flags[r[src]] == true; } which is turning the flag value at the remove string indexed at src to true... so if you start out with PLEASE HELP as your str and LEA as your remove you will be setting in your flag table at 0,1,2... t|t|t but after that you will get an out of bounds exception because r doesn't have have anything greater than 2 in it... even using there example you get an out of bounds exception... Am is there code example unworkable? Entire function string removeChars( string str, string remove ){ char[] s = str.toCharArray(); char[] r = remove.toCharArray(); bool[] flags = new bool[128]; // assumes ASCII! int len = s.Length; int src, dst; // Set flags for characters to be removed for( src = 0; src < len; ++src ){ flags[r[src]] = true; } src = 0; dst = 0; // Now loop through all the characters, // copying only if they aren’t flagged while( src < len ){ if( !flags[ (int)s[src] ] ){ s[dst++] = s[src]; } ++src; } return new string( s, 0, dst ); } as you can see, r comes from the remove string. So in my example the remove string has only a size of 3 while my str string has a size of 11. len is equal to the length of the str string. So it would be 11. How can I loop through the r string since it is only size 3? I haven't compiled the code so I can loop through it, but just looking at it I know it won't work. I am thinking they wanted to loop through the r string... in other words they got the length of the wrong string here.

• Moved to SSD and now getting "the disk drive for / is not ready yet"

  - by dmt0

  I moved my Ubuntu 12.04 install over to an SSD drive. Copied all directories except for the ones most often written to - var, tmp, ... Reinstalled grub into SSD by booting with live CD and following the commands in this post: How to move Ubuntu to an SSD This seemed to work fine, because when I press "e" in grub menu, I see the expected UUIDs. But right after grub I get could not log bootup: Address already in use the disk drive for / is not ready yet or not present. If I skip, I get same for /tmp /run, and other dirs If I go into manual recovery and do mount -n -o remount,rw / it turns out that everything can mount no problem. Can't get my head around this one. My fstab seems right. grub is right. AHCI in bios is enabled. Why is this happening? What can I do to fix it?

When we first started talking about "paper-free" most of the reasons raised to pursue this direction were "green" reasons.  I'm glad to see that the thinking has moved on to questions about how getting rid of paper and digitizing processes helps improve customer engagement.  And the bottom line.  And process responsiveness.  Not that the "green" reasons have gone away, but it's nice to see a maturation in the BUSINESS reasons to get rid of paper. Our World Paper Free Handbook (do not, do not, do not print it!) looks at how less paper in the workplace delivers significant benefits. Key findings show eliminating paper from processes can improve the responsiveness of customer service by 300 percent. Removing paper from business processes and moving content to PCs and tablets has the added advantage of helping companies adopt mobile-enable processes and eliminate elapsed time, lost forms, poor data and re-keying. To effectively mobile-enable processes and reduce reliance on paper, data should be captured as close to the point of origination as possible, which makes information easily available to whomever needs it, wherever they are, in the shortest time possible. This handbook summarizes the value of automating manual, paper-based processes. It then goes a step beyond to provide actionable steps that will set you on the path to productivity, profitability, and, yes, less paper.  Get your copy today and send the link around to your peers and colleagues.  Here's the link; please share it! http://www.aiim.org/Research-and-Publications/Research/AIIM-White-Papers/WPFD-Revolution-Handbook And don't miss out on the real world discussions about increasing engagement with WebCenter in new webinars being offered over the next couple of weeks:  October 30, 2012:  ResCare Solves Content Lifecycle Challenges with Oracle WebCenter November 1, 2012: WebCenter Content for Applications: Streamline Processes with Oracle WebCenter Content Management for Human Resources Applications Available On-Demand:  Using Oracle WebCenter to Content-Enable Your Business Applications

• The Minimalist Approach to Content Governance - Request Phase

  - by Kellsey Ruppel

  Originally posted by John Brunswick. For each project, regardless of size, it is critical to understand the required ownership, business purpose, prerequisite education / resources needed to execute and success criteria around it. Without doing this, there is no way to get a handle on the content life-cyle, resulting in a mass of orphaned material. This lowers the quality of end user experiences.     The good news is that by using a simple process in this request phase - we will not have to revisit this phase unless something drastic changes in the project. For each of the elements mentioned above in this stage, the why, how (technically focused) and impact are outlined with the intent of providing the most value to a small team. 1. Ownership Why - Without ownership information it will not be possible to track and manage any of the content and take advantage of many features of enterprise content management technology. To hedge against this, we need to ensure that both a individual and their group or department within the organization are associated with the content. How - Apply metadata that indicates the owner and department or group that has responsibility for the content. Impact - It is possible to keep the content system optimized by running native reports against the meta-data and acting on them based on what has been outlined for success criteria. This will maximize end user experience, as content will be faster to locate and more relevant to the user by virtue of working through a smaller collection. 2. Business Purpose Why - This simple step will weed out requests that have tepid justification, as users will most likely not spend the effort to request resources if they do not have a real need. How - Use a simple online form to collect and workflow the request to management native to the content system. Impact - Minimizes the amount user generated content that is of low value to the organization. 3. Prerequisite Education Resources Needed Why - If a project cannot be properly staffed the probability of its success is going to be low. By outlining the resources needed - in both skill set and duration - it will cause the requesting party to think critically about the commitment needed to complete their project and what gap must be closed with regard to education of those resources. How - In the simple request form outlined above, resources and a commitment to fulfilling any needed education should be included with a brief acceptance clause that outlines the requesting party's commitment. Impact - This stage acts as a formal commitment to ensuring that resources are able to execute on the vision for the project. 4. Success Criteria Why - Similar to the business purpose, this is a key element in helping to determine if the project and its respective content should continue to exist if it does not meet its intended goal. How - Set a review point for the project content that will check the progress against the originally outlined success criteria and then determine the fate of the content. This can even include logic that will tell the content system to remove items that have not been opened by any users in X amount of time. Impact - This ensures that projects and their contents do not live past their useful lifespans. Just as with orphaned content, non-relevant information will slow user's access to relevant materials for the jobs. Request Phase Summary With a simple form that outlines the ownership of a project and its content, business purpose, education and resources, along with success criteria, we can ensure that an enterprise content management system will stay clean and relevant to end users - allowing it to deliver the most value possible. The key here is to make it straightforward to make the request and let the content management technology manage as much as possible through metadata, retention policies and workflow. Doing these basic steps will allow project content to get off to a great start in the enterprise! Stay tuned for the next installment - the "Create Phase" - covering security access and workflow involved in content creation, enabling a practical layer of governance over our enterprise content repository.

• How to Send the Contents of the Clipboard to a Text File via the Send to Menu

  - by Jason Faulkner

  We have previously covered how to send the contents of a text file to the Windows Clipboard with a simple Send To shortcut, but what if you want to do the opposite? That is: send the contents of the clipboard to a text file with a simple shortcut. No problem. Here’s how. Copy the ClipOut Utility While Windows offers the command line tool ‘clip’ as a way to direct console output to the clipboard, it does not have a tool to direct the clipboard contents to the console. To do this, we are going to use a small utility named ClipOut (download link at the bottom). Simply download and extract this file to a location in your Windows PATH variable (if you don’t know what this means, just extract the EXE to your C:\Windows folder) and you are ready to go. Add the Send To Shortcut Open your Send To folder location by going to Run > shell:sendto Create a new shortcut with the command: CMD /C ClipOut > Note the above command will overwrite the contents of the selected file. If you would like to append to the contents of the selected file, use this command instead: CMD /C ClipOut >> Of course, you could make shortcuts for both. Give a descriptive name to the shortcut. You’re finished. Using this shortcut will now send the text contents copied to your Windows Clipboard to the selected file. It is important to note that the ClipOut tool only supports outputting text. If you had binary data copied to your clipboard, then the output would be empty. Changing the Icon By default, the icon for the shortcut will appear as a command prompt, but you can easily change this by editing the properties of the shortcut and clicking the Change Icon button. We used an icon located in “%SystemRoot%\System32\shell32.dll”, but any icon of your liking will do. As an additional tweak, you can set the properties of the shortcut to run minimized. This will prevent the command window from “blinking” when the send to command is run (instead it will blink in your taskbar, which is hardly noticeable). Links Download ClipOut Utility

• The type of programmer I want to be [closed]

  - by Aventinus_

  I'm an undergraduate Software Engineer student, although I've decided that pure programming is what I want to do for the rest of my life. The thing is that programming is a vast field and although most of its aspects are extremely interesting, soon or later I'll have to choose one (?) to focus on. I have several ideas on small projects I'd like to develop this summer, having in mind that this will gain me some experience and, in the best scenario, some cash. But the most important reason I'd like to develop something close to “professional” is to give myself direction on what I want to do as a programmer. One path is that of the Web Programmer. I enjoy PHP and MySQL, as well as HTML and CSS, although I don't really like ASP.NET. I can see myself writing web apps, using the above technologies, as well as XML and Javascript. I also have a neat idea on a Facebook app. The other path is that of the Desktop Programmer. This is a little more complicated cause I really-really enjoy high level languages such as Java and Python but not the low level ones, such as C. I use both Linux and Windows for the last 6 years and I like their latest DEs (meaning Gnome Shell and Metro). I can see myself writing desktop applications for both OSs as long as it means high level programming. Ideally I'd like being able to help the development of GNOME. The last path that interests me is the path of the Smartphone Programmer. I have created some sample applications on Android and due to Java I found it a quite interesting experience. I can also see myself as an independent smartphone developer. These 3 paths seem equally interesting at the moment due to the shallowness of my experience, I guess. I know that I should spend time with all of them and then choose the right one for me but I'd like to know what are the pros and cons in terms of learning curve, fun, job finding and of course financial rewards with each of these paths. I have fair or basic understanding of the languages/technologies I described earlier and this question will help me choose where to focus, at least for now.

• What do you need to know to be a world-class master software developer? [closed]

  - by glitch

  I wanted to bring up this question to you folks and see what you think, hopefully advise me on the matter: let's say you had 30 years of learning and practicing software development in front of you, how would you dedicate your time so that you'd get the biggest bang for your buck. What would you both learn and work on to be a world-class software developer that would make a large impact on the industry and leave behind a legacy? I think that most great developers end up being both broad generalists and specialists in one-two areas of interest. I'm thinking Bill Joy, John Carmack, Linus Torvalds, K&R and so on. I'm thinking that perhaps one approach would be to break things down by categories and establish a base minimum of "software development" greatness. I'm thinking: Operating Systems: completely internalize the core concepts of OS, perhaps gain a lot of familiarity with an OSS one such as Linux. Anything from memory management to device drivers has to be complete second nature. Programming Languages: this is one of those topics that imho has to be fully grokked even if it might take many years. I don't think there's quite anything like going through the process of developing your own compiler, understanding language design trade-offs and so on. Programming Language Pragmatics is one of my favorite books actually, I think you want to have that internalized back to back, and that's just the start. You could go significantly deeper, but I think it's time well spent, because it's such a crucial building block. As a subset of that, you want to really understand the different programming paradigms out there. Imperative, declarative, logic, functional and so on. Anything from assembly to LISP should be at the very least comfortable to write in. Contexts: I believe one should have experience working in different contexts to truly be able to appreciate the trade-offs that are being made every day. Embedded, web development, mobile development, UX development, distributed, cloud computing and so on. Hardware: I'm somewhat conflicted about this one. I think you want some understanding of computer architecture at a low level, but I feel like the concepts that will truly matter will be slightly higher level, such as CPU caching / memory hierarchy, ILP, and so on. Networking: we live in a completely network-dependent era. Having a good understanding of the OSI model, knowing how the Web works, how HTTP works and so on is pretty much a pre-requisite these days. Distributed systems: once again, everything's distributed these days, it's getting progressively harder to ignore this reality. Slightly related, perhaps add solid understanding of how browsers work to that, since the world seems to be moving so much to interfacing with everything through a browser. Tools: Have a really broad toolset that you're familiar with, one that continuously expands throughout the years. Communication: I think being a great writer, effective communicator and a phenomenal team player is pretty much a prerequisite for a lot of a software developer's greatness. It can't be overstated. Software engineering: understanding the process of building software, team dynamics, the requirements of the business-side, all the pitfalls. You want to deeply understand where what you're writing fits from the market perspective. The better you understand all of this, the more of your work will actually see the daylight. This is really just a starting list, I'm confident that there's a ton of other material that you need to master. As I mentioned, you most likely end up specializing in a bunch of these areas as you go along, but I was trying to come up with a baseline. Any thoughts, suggestions and words of wisdom from the grizzled veterans out there who would like to share their thoughts and experiences with this? I'd really love to know what you think!

• stuck in busybox after update

  - by Lyra500

  I should start out by saying that I am not very tech savvy and have done my best to understand what is going on here from reading other people's posts and have fumbled my way through several attempted fixes without getting anywhere... I run ubuntu 12.04 on an admittedly cheap laptop from ebuyer and in spite of being cheap and not a brand laptop I have never had any major problems with it. Since updating to 12.04 when it was released the boot-up process has always been slow. Logging in takes about 30secs longer than it used to and if I closed my laptop and opened it again instead of being met with a login screen I'd be met with a black screen with a white mouse. As all of these problems had a behavior-changing fix (don't close laptop, patiently wait for login, etc.) I didn't think of reporting any of the issues. Last night when the update manager prompted me that there were updates available I duly did them as I usually do. At the time a bug report came up and I cannot remember what it said but I reported the bug as I was prompted to do. Then this morning when I started up my laptop it went through the usual sequence, GRUB, purple screen with 'ubuntu' etc. and then when it tried to boot up it went into BusyBox and I have not been able to do anything to solve this. I have tried going into the GRUB menu and starting previous versions but I come to the same point - busybox. I have borrowed another rather elderly laptop with Windows Vista to try and download Boot Repair and Ubuntu and burn them onto CD. I tried downloading boot repair five times, to laptop, CD and USB. Every time it would download and burn fine but then the windows laptop would tell me that 1% did not download properly and my laptop would not run the USB or CD upon booting. I then tried to download ubuntu and make a livecd, twice, but again was told that 1% did not download properly and again my laptop will not run ubuntu from the CD upon booting even if/when I went into the f2 menu and changed the menu priority (if that's what you call it) for booting up to make sure it was definitely trying the USB/CD first. This is the message I get from busybox: BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands I have tried 'exit' but it mentions things about 'kernal panic' and 'tried to quit init!' and 'can't find /root/dev/console : no such file'. I know that the problem is probably caused by a problem with a kernal caused by the update last night, but I couldn't honestly tell you exactly what was updated and without being able to boot from a livecd I'm not sure how to go about fixing this. As I said, I am not tech savvy and have done what I can to try and find a solution to the problem but I'm starting to feel like I'm out of options. Does anyone have any ideas?

• How to set up an rsync backup to Ubuntu securely?

  - by ws_e_c421

  I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

• Laptop freezes and seems to crash, but continues working after waiting for a few minutes [closed]

  - by Corwin

  I've had this old notebook laying around and because i was missing a second machine (My wife usually steals the first ;) ) I considered installing Linux. As a php developer I work with Linux servers (usually fedora) on a daily basis and because its an older machine that I want to use for development, linux seemed the best option. Speedwise I expected a good experience, better than Windows 7 on the same machine. The results where terrible. I tried ubuntu 12.04. The shell never got past showing the background. The system doesn't freeze since the mouse still works and I can use ctrl+alt+f2 etc to enter terminal mode. I expected hardware problems en even exchanged the harddisk en Ram memory. No luck though, so I started over and tried 11.10 Same results so I tried 10.04.4 which did install properly. Not sure if unity was the problem, but it seems likely. But then I tried simply things like surfing on the net, the system frooze and I thought it crashed so after a few minutes I pulled the plug and rebooted. But it happened again and I waited. After a few minutes the system came back to life like nothing happened. Long story short. Besides the fact that the entire interface is very sluggish, any and all graphical functions freezes the system. The more elaborate the animation would be, the longer it freezes. I switch chromium from window to fullscreenmode and had to wait 15 minutes to continue. I don't see the animation that's probably supposed to be in between. It just freezes and then after unfreezing its fullscreen. I don't think its a bug. I suspect the problem is with my graphics card. Like I said, its and old system. So old that I can't even find the original Ati drivers anywere. (I'll post the details of my system at the end of my post) I'm at a loss as to what to do next. I tried other Distro's. So far only dreamlinux works normally. Linux Mint won't start as a live CD. I think I simply need a driver update but I can't find them anywhere. Does anyone have the same experience ? Maybe even someone who has or had the same notebook running Ubuntu at some point ? Anyway, here are the specs: http://www.nec-driver.com/nec-driver/NEC-Versa-P550---FP550-Driver_421.html

• ssh + tinyproxy: poor performance

  - by Paul

  I am currently in China and I would like to still visit some blocked websites (facebook, youtube). I have VPS in the USA and I have installed tinyproxy on it. I log in on my VPS with SSH port-forwarding and I have configured my browser appropriately. Everything works more or less: I can surf to those websites but everything is inusually slow and sometimes data transfer stops abruptly. This probably has to do with the fact that I see some errors in my shell on the VPS like : channel 6: open failed: connect failed: Also in the log-file of tinyproxy I see some bad things: ERROR Sep 06 14:52:14 [28150]: getpeer_information: getpeername() error: Transport endpoint is not connected ERROR Sep 06 14:52:15 [28153]: writebuff: write() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:15 [28168]: readbuff: recv() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:15 [28151]: readbuff: recv() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:15 [28143]: readbuff: recv() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:17 [28147]: writebuff: write() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:23 [28137]: writebuff: write() error "Connection reset by peer" on file descriptor 7 ERROR Sep 06 14:52:26 [28168]: getpeer_information: getpeername() error: Transport endpoint is not connected ERROR Sep 06 14:52:27 [28186]: read_request_line: Client (file descriptor: 7) closed socket before read.

• Watchguard Firewall WebBlocker Regular Expression for Multiple Domains?

  - by Eric

  I'm pretty sure this is really a regex question, so you can skip to REGEX QUESTION if you want to skip the background. Our primary firewall is a Watchguard X750e running Fireware XTM v11.2. We're using webblocker to block most of the categories, and I'm allowing needed sites as they arise. Some sites are simple to add as exceptions, like Pandora radio. That one is just a pattern matched exception with "padnora.com/" as the pattern. All traffic from anywhere on pandora.com is allowed. I'm running into trouble on more sophisticated domains that reference content off of their base domains. We'll take GrooveShark as a sample. If you go to http://grooveshark.com/ and view page source, you'll see hrefs referring to gs-cdn.net as well as grooveshar.com. So adding a WebBlocker exception to grooveshark.com/ is not effective, and I have to add a second rule allowing gs-cdn.net/ as well. I see that the WebBlocker allows regex rules, so what I'd like to do in situations like this is create a single regex rule that allows traffic to all the needed domains. REGEX QUESTION: I'd like to try a regex that matches grooveshark.com/ and gs-cdn.net/. If anybody can help me write that regex, I'd appreciate it. Here is what is in the WatchGuard documentation from that section: Regular expression Regular expression matches use a Perl-compatible regular expression to make a match. For example, .[onc][eor][gtm] matches .org, .net, .com, or any other three-letter combination of one letter from each bracket, in order. Be sure to drop the leading “http://” Supports wild cards used in shell script. For example, the expression “(www)?.watchguard.[com|org|net]” will match URL paths including www.watchguard.com, www.watchguard.net, and www.watchguard.org. Thanks all!

• Xorg server won't start after fresh install of Debian 5.04, screen goes blank (Intel Atom D510(Pinet

  - by Kamil Zadora

  Hello, I have installed Debian 5.04 Lenny on my new Intel D510MO motheboard. I fixed some issues with incorrect drive mapping (for some reason during installation my hdd was on sdb, after a restart it is under sda - fixed in grub), and now I am struggling with getting graphical enviroment up and running, I installed the graphical enviroment using the Debian installer. I am not an linux expert by any means, I assume that I need to edit the xorg.conf file. Any hints appreciated!

• Account Lockout with pam_tally2 in RHEL6

  - by Aaron Copley

  I am using pam_tally2 to lockout accounts after 3 failed logins per policy, however, the connecting user does not receive the error indicating pam_tally2's action. (Via SSH.) I expect to see on the 4th attempt: Account locked due to 3 failed logins No combination of required or requisite or the order in the file seems to help. This is under Red Hat 6, and I am using /etc/pam.d/password-auth. The lockout does work as expected but the user does not receive the error described above. This causes a lot of confusion and frustration as they have no way of knowing why authentication fails when they are sure they are using the correct password. Implementation follows NSA's Guide to the Secure Conguration of Red Hat Enterprise Linux 5. (pg.45) It's my understanding that that only thing changed in PAM is that /etc/pam.d/sshd now includes /etc/pam.d/password-auth instead of system-auth. If locking out accounts after a number of incorrect login attempts is required by your security policy, implement use of pam_tally2.so. To enforce password lockout, add the following to /etc/pam.d/system-auth. First, add to the top of the auth lines: auth required pam_tally2.so deny=5 onerr=fail unlock_time=900 Second, add to the top of the account lines: account required pam_tally2.so EDIT: I get the error message by resetting pam_tally2 during one of the login attempts. user@localhost's password: (bad password) Permission denied, please try again. user@localhost's password: (bad password) Permission denied, please try again. (reset pam_tally2 from another shell) user@localhost's password: (good password) Account locked due to ... Account locked due to ... Last login: ... [user@localhost ~]$

• Windows Server 2008 / SQL 2008 Licensing for Authenticated Web Application

  - by MikeM

  Hello, I'm trying to crunch some numbers to see what the software costs involved are for hosting an application we are developing. Users will not be anonymous - they will need to log in. SQL Server 2008: SQL Server licensing is easy - it will be licensed per-processor. No real fuss there. The cost of CALs would be much higher for the number of users as compared to the processor licenses. Windows Server 2008: This is where it gets trickier. We need to license the OS for both the web servers (there will be a couple) plus the database servers (also a couple). The Web Servers could run on the Web Edition without a need for CALs, but if you continue reading, you will see that may not matter much because I will likely have user CALs for each user anyway. We can't use the "External Connector" for any of the Windows licenses, because that doesn't cover customers who are paying to access a hosted application. We can't use the Web Edition for the SQL Servers because that license only allows database running on Web Edition to host data for the local web application (i.e. other web servers can't connect to it). So that leaves us with the "full" editions of Windows Server for the database server OS. I find this a little rediculous, and I feel as though I must be missing something, but it looks to me like I will actually need to buy a CAL for every user who signs up to use our service. I feel like I'm missing something because that means that for every user, I have to shell out $40 for a CAL. That could be one or two years' worth of revenue from each user for an inexpensive service! Is there any way to serve a web application to authenticated users without paying for individual Windows Server CALs, if the web servers and SQL servers are seperate boxes?

• Ubuntu 9.10 RSA authentication: ssh fails, filezilla runs fine

  - by MariusPontmercy

  This is quite a mistery for me. I usually use passwordless RSA authentication to login into my remote *nix servers with ssh and sftp. Never had any problem until now. I cannot connect to an Ubuntu 9.10 machine: user@myclient$ ssh -i .ssh/Ganymede_key [email protected] [...] debug1: Host 'ganymede.server.com' is known and matches the RSA host key. debug1: Found key in /home/user/.ssh/known_hosts:14 debug2: bits set: 494/1024 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: .ssh/Ganymede_key (0xb96a0ef8) debug2: key: .ssh/Ganymede_key ((nil)) debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Offering public key: .ssh/Ganymede_key debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Trying private key: .ssh/Ganymede_key debug1: read PEM private key done: type RSA debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug2: we did not send a packet, disable method debug1: Next authentication method: keyboard-interactive debug2: userauth_kbdint debug2: we sent a keyboard-interactive packet, wait for reply debug2: input_userauth_info_req debug2: input_userauth_info_req: num_prompts 1 Then it falls back to password authentication. If I disable password authentication on the remote machine my connection attempt just fails with a "Permission denied (publickey)." state. Same thing for sftp from command line. The "funny" thing is that the exact same RSA key works like a charm with a Filezilla sftp session instead: 12:08:00 Trace: Offered public key from "/home/user/.filezilla/keys/Ganymede_key" 12:08:00 Trace: Offer of public key accepted, trying to authenticate using it. 12:08:01 Trace: Access granted 12:08:01 Trace: Opened channel for session 12:08:01 Trace: Started a shell/command 12:08:01 Status: Connected to ganymede.server.com 12:08:02 Trace: CSftpControlSocket::ConnectParseResponse() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Retrieving directory listing... 12:08:02 Trace: CSftpControlSocket::SendNextCommand() 12:08:02 Trace: CSftpControlSocket::ChangeDirSend() 12:08:02 Command: pwd 12:08:02 Response: Current directory is: "/root" 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Trace: CSftpControlSocket::ParseSubcommandResult(0) 12:08:02 Trace: CSftpControlSocket::ListSubcommandResult() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Directory listing successful Any thoughts?

• Handle filename with spaces inside Bash-script

• Accidentally deleted symlink libc.so.6 in CentOS 6.4. How to get sudo privilege to re-create it?

  - by Eric

  I accidentally deleted the symbol link /lib64/libc.so.6 - /lib64/libc-2.12.so with $ sudo rm libc.so.6 Then I can not use anything including ls command. The error appears for any command I type ls: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory I've tried $ export LD_PRELOAD=/lib64/libc-2.12.so After this I can use ls and ln ..., but still can not use sudo ln ..., sudo -E ln ..., sudo su or even su. I always get this err sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory or su: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory It seems LD_PRELOAD works only for the current shell session of my account, but not for a new account like root or a new session. It's a remote server so I can not use a live CD. I now have a ssh bash session alive but can not establish new ones. I have sudo privilege, but don't have root password. So currently my problem is I need to run sudo sln -s libc-2.12.so libc.so.6 to re-create the symlink libc.so.6, but I can not run sudo without libc.so.6. How can I fix it? Thanks~

• Adding an user to samba

  - by JustMaximumPower

  I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.
