  • zeroconf (bonjour/avahi): macs do not see linuxes and vice versa

    - by codesnik
    In my home network I have several OS X boxes and several Ubuntu boxes. each Ubuntu box sees other boxes via zeroconf. I can "ssh ubuntu1.local" and "ping ubuntu1.local" from "ubuntu2.local", but both fail to lookup OSX boxes. and other way around, I can "ssh mini1.local" from "mbair.local". but it doesn't see "ubuntu1.local" why? do ubuntu and osx use different flavours of zeroconf? could be ubuntu, or osx tweaked to use common flavour?

  • OpenVPN: ERROR: could not read Auth username from stdin

    - by user56231
    I managed to setup openvpn but now I want to integrate a user/pass authentication method so, even though I haven't added the auth-nocache in the server config, whenever I try to connect it returns with the following message on the client side: ERROR: could not read Auth username from stdin My server.conf file contains basic stuff, everything works up untill I try to implement this for of authentication. mode server dev tun proto tcp port 1194 keepalive 10 120 plugin /usr/lib/openvpn/openvpn-auth-pam.so login client-cert-not-required username-as-common-name auth-user-pass-verify /etc/openvpn/auth.pl via-env ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem user nobody group nogroup server 10.8.0.0 255.255.255.0 persist-key persist-tun #persist-local-ip status openvpn-status.log verb 3 client-to-client push "redirect-gateway def1" push "dhcp-option DNS 10.8.0.1" log-append /var/log/openvpn comp-lzo I searched all over the net for a solution and all answers seems to be related to the auth-nocache param which I haven't set. The directive auth-user-pass-verify /etc/openvpn/auth.pl via-env points to a script which is executed to perform the authentication. A false authentication should result in a exit 1 while a true one should result with exit 0. For testing, that script auth.pl returns exit 0 no matter what the input is but it seems that the file is not executed before the error raises. auth.pl file contents: #!/usr/bin/perl my $user = $ENV{username}; my $passwd = $ENV{password}; printf("$user : $passwd\n"); exit 0; Any ideas?

  • NTFS Permissions-Special Permissions not working

    - by Srinivas
    I am using Windows 2008 R2 Server having a CENTRAL SHARED FOLDER (CENTRALSTORAGE). We are trying to give Domain Users in the Network access as like User1-\CentralStorage\IT\User1 and User2-\CentralStorage\IT\User2. But it is not working when i try to login to that user in Windows XP system which is already a registered computer of domain. Will someone help me in guiding how to declare permissions like \CentralStorage\IT - this is a Main Directory and should be accessed to VIEW folder sub-directories but not to DELETE/RENAME this folder. \CentralStorage\IT\User1 - Full Control to the User1 to ADD SUB-FOLDERS AND FILES. But not to delete/rename this folder name. I gave access using Special Permissions but it is showing as Access Denied when i logon and try to access. Kindly provide me a solution for the same.

  • How can I reorder parts of a video file

    - by sandeep
    I have download a mkv movie file which gave me 3 files suffixed .001, .002, and .003.

Can anyone tell me how can join this parts of movie with correct position or how I can convert .003 file into .001 file.

  • ajax.googleapis.com stopping my Firefox

    - by Oscar Reyes
    Today for some strange reason, Firefox stops working properly because it is trying to fetch something from ajax.googleapis.com. Is there something I can do to avoid this? Safari and Chrome work just fine. I tried uninstalling Firebug and clearing the cache. The only thing that worked was disabling the JavaScript altogether. This seems to be the culprit link: http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js What can I do? EDIT I think I have found where the problem is. My proxy is serving one byte at a time the file, so firefox consume it at that peace. What I don't understand is why Safari and Chrome takes it right away. What I did last night was, leave the FF open all the night to give him change to load the file, my hope was that I got cached and the next time there was no need to go for it. Today in the morning, the page load successfully but the page was not cached, because the next request failed the same. Here's a video showing the problem:

  • Can I prevent a particular program from showing up in the taskbar on Windows XP?

    - by jsnlxndrlv
    I have a program that I need to run more or less continuously, but which I won't need to access very frequently. Currently, launching the program creates a window and causes the program to appear on the taskbar. I'm fine with the program window appearing, but I'd just as soon the taskbar be reserved for programs that I need to switch between frequently—it would be superior for this program to only appear as an icon in the notification area, if at all. Is this possible? How do I do this?

  • Converting PDF eBooks into a Kindle format

    - by Ender
    Over the past couple of years I've amassed quite a collection of guides, tutorials and ebooks in PDF format. A lot of these are quite useful for work, especially PDF documentation, and rather than have to be at a computer every time I want to read how to do something in Sitecore or to read through a software testing ebook I'd like to do it on my brand-spanking-new Kindle. However, even though there is now a native PDF reader on the Kindle due to the nature of PDF's they are practically unreadable. The text doesn't wrap due to how PDF's are sized and so far after a bunch of Google searches I've yet to find a viable solution to get my PDF's converted into a readable Kindle format. Sometimes these books have code or pictures/tables in them, but most of the time they're text-heavy and to be honest I'd be surprised if there wasn't a free tool to handle the converting of PDF to one of the (seemingly many) Kindle formats. So, can anyone help me out with this? EDIT: I've tried Calibre, and have checked their forums to play with some of the advanced settings, yet the solutions available seem to be extremely poor, especially if the book you're attempting to read contains equations, code, or anything outside of plain text. I've also tried Amazon's conversion service, which wasn't much help with such documents. The best way I have found so far is to build the entire thing over again in ePub or RTF format and convert to MOBI from there. This works for text-heavy books with tables, but anything technical still isn't covered. Can anyone help with this?

  • USB Hub powers down in sleep mode on Win 7 64

    - by Andy B
    This question has been asked before but not answered. I would like the USB hub to remain on in sleep so I can wake up the laptop from an external keyboard and mouse. I have set all the device drivers by unchecking allow this device to be powered down and disabled selective suspend in control panel but the hub still powers down. If I plug a keyboard or mouse directly in to the PC they remain powered and wake the computer its only when they are connected through the hub there is a problem. I have another PC running Win 7 32. If I set this up in exactly the same way the hub remains powered in sleep. Both PC's are Toshiba Satellites with multi-core celerons but one runs Win 7 32 the other Win 7 64. BIOS settings are the same. Any help would be appreciated even confirmation that this is a feature of Win 7 64.

  • Lion MacBook Pro will not load webpages with DNS just after wake

    - by NReilingh
    I'm working with a 2011 MacBook Pro running Lion (10.7.2), that after waking from sleep (i.e. opening the lid) takes an inordinately long amount of time (2-3 minutes or more) to get a usable internet connection. Upon waking, the wi-fi icon signifies it is negotiating a network connection, and completes one a few seconds later. At this point, network diagnostics will not show any issues, and everything in Network preferences looks as normal: I'm connected to the proper network, have the right IP address and gateway, and DNS settings are correct. However, any site accessed with a domain name (like http://www.google.com) in Safari will return the "You are not connected to the Internet." error. Accessing a site directly, say, with Google's 74.125.226.212, is successful. Yet, Network Diagnostics will insist that DNS is functioning properly. After a few minutes, the following lines will be printed to the Console log, and regular behavior will be restored. 11/18/11 8:11:31.288 PM airportd: _doAutoJoin: Already associated to “Wireless”. Bailing on auto-join. 11/18/11 8:11:32.000 PM kernel: en1: BSSID changed to 00:25:9c:63:91:bd This behavior occurs only when waking from sleep--not when turning wi-fi on and off. This problem also occurs when using a wired Ethernet connection. As per this thread, I have tried flushing the DNS cache and wiping the wireless network from memory (it's not a protected network). Neither have worked.

  • Tortoise SVN Error Validating Server Certificate

    - by theplatz
    I just updated the certificate on one of my sites due to the old one expiring. The new certificate verifies fine in Internet Explorer 9, Chrome, and Firefox 4 - but when trying to browse/check out the repository with TortoiseSVN, I get the following error: Error validating server certificate for https://xxx.xxx.com:443: Unknown certificate issuer. Fingerprint: 96:b3:fa:19:bd:4a:ec:c2:bc:19:33:b8:25:2a:0a:47:28:41:07:d0 Distinguished name: (c) 2009 Entrust, Inc., www.entrust.net/rpa is incorporated by reference, Entrust, Inc., US Do you want to proceed? Accept permanently | Accept once | Reject Clicking Accept permanently will work, but this is less than ideal. This problem seems to be related to TortoiseSVN and not the certificate, which checks out fine at http://sslinstallcheck.entrust.net/SIC/jsp/MainWebAddress.jsp and http://www.digicert.com/help/. Any ideas on what could be wrong?

  • Losing partitions after every reboot

    - by Winston Smith
    I have an Acer laptop with one hard disk, which up until yesterday had 4 partitions: Recovery Partition (13GB) C: (140GB) D: (130GB) OEM Partition (10GB) I read that the OEM partition has all the stuff needed to restore the laptop to the factory settings, but since I'd already created restore disks and I needed the space, I wanted to get rid of it. Yesterday, I used diskpart to do that. In diskpart, I selected the OEM partition and issued the delete partition override command which removed it. Then I extended the D: partition into the unused space using windows disk management. Everything worked fine, until I rebooted my laptop, at which point the D: drive vanished. Looking in windows disk management again, I can see that there's an OEM partition of 140GB, which is obviously my D: drive. So I used EASEUS Partition Master and assigned a drive letter to the 'OEM' partition and I was able to access my files again. However, every time I reboot, it reverts back. How do I fix this permanently?

  • ksh Auto-Completion PuTTY Configuration

    - by Nitrodist
    I'm having a bit of a problem configuring my PuTTY client to work with the auto-completion feature in the ksh shell. I do a listing on the root with the directories /home and /homeroot and it returns the directories in a list just fine. I can't select it, though, by hitting X = (where X is the number). /home/nitrodist>ls /h #hits esc + = 1) home/ 2) homeroot/ #hits 2 + = for the 'homeroot' dir 1) home/ 2) homeroot/ #hits just the '=' key. 1) home/ 2) homeroot/ Any ideas? I've su -'d to another user who can actually do it with their PuTTY session and I can't do it there, which makes me think it's a PuTTY configuration issue. This is running on a ksh93 shell on HP-UX, if that makes any difference. Here's my ksh config: /home/campbelm>set -o Current option settings allexport off bgnice on emacs off errexit off gmacs off ignoreeof off interactive on keyword off markdirs off monitor on noexec off noclobber off noglob off nolog off notify off nounset off privileged off restricted off trackall off verbose off vi on viraw on xtrace off /home/campbelm>

  • Using pivot tables to group transactions

  • Industry perspectives on managing content

    - by aahluwalia
    Earlier this week I was noodling over a topic for my first blog post. My intention for this blog is to bring a practitioner's perspective on ECM to the community; to share and collaborate on best practices and approaches that address today's business problems. Reviewing my past 14 years of experience with web technologies, I wondered what topic would serve as a good "conversation starter". During this time, I received a call from a friend who was seeking insights on how content management applies to specific industries. She approached me because she vaguely remembered that I had worked in the Health Insurance industry in the recent past. She wanted me to tell her about the specific business needs of this industry. She was in for quite a surprise as she found out that I had spent the better part of a decade managing content within the Health Insurance industry and I discovered a great topic for my first blog post! I offer some insights from Health Insurance and invite my fellow practitioners to share their insights from other industries. What does content management mean to these industries? What can solution providers be aware of when offering solutions to these industries? The United States health care system relies heavily on private health insurance, which is the primary source of coverage for approximately 58% Americans. In the late 19th century, "accident insurance" began to be available, which operated much like modern disability insurance. In the late 20th century, traditional disability insurance evolved into modern health insurance programs. The first thing a solution provider must be aware of about the Health Insurance industry is that it tends to be transaction intensive. They are the ones who manage and administer our health plans and process our claims when we visit our health care providers. It helps to keep in mind that they are in the business of delivering health insurance and not technology. You may find the mindset conservative in comparison to the IT industry, however, the Health Insurance industry has benefited and will continue to benefit from the efficiency that technology brings to traditionally paper-driven processes. We are all aware of the impact that Healthcare reform bill has had a significant impact on the Health Insurance industry. They are under a great deal of pressure to explore ways to reduce their administrative costs and increase operational efficiency. Overall, administrative costs of health insurance include the insurer's cost to administer the health plan, the costs borne by employers, health-care providers, governments and individual consumers. Inefficiencies plague health insurance, owing largely to the absence of standardized processes across the industry. To achieve this, industry leaders have come together to establish standards and invest in initiatives to help their healthcare provider partners transition to the next generation of healthcare technology. The move to online services and paperless explanation of benefits are some manifestations of technological advancements in health insurance. Several companies have adopted Toyota's LEAN methodology or Six Sigma principles to improve quality, reduce waste and excessive costs, thereby increasing the value of their plan offerings. A growing number of health insurance companies have transformed their business systems in the past decade alone and adopted some form of content management to reduce the costs involved in administering health plans. The key strategy has been to convert paper documents and forms into electronic formats, automate the content development process and securely distribute content to various audiences via diverse marketing channels, including web and mobile. Enterprise content management solutions can enable document capture of claim forms, manage digital assets, integrate with Enterprise Resource Planning (ERP) and Human Capital Management (HCM) solutions, build Business Process Management (BPM) processes, define retention and disposition instructions to comply with state and federal regulations and allow eBusiness and Marketing departments to develop and deliver web content to multiple websites, mobile devices and portals. Content can be shared securely within and outside the organization using Information Rights Management.  At the end of the day, solution providers who can translate strategic goals into solutions that maximize process automation, increase ease of use and minimize IT overhead are likely to be successful in today's health insurance environment.

  • FIX: A network error occurred during SQL Server Native Client installation

    - by Greg Low
    One of the things that I have been pestering the SQL team to do is to name their updates according to what is contained in them. For example, instead of just: sqlncli.msi What I'd prefer is that the file was called something like: SQLServerNativeClient2k8SP1CU3x64.msi So I normally rename them as soon as I receive them, to avoid confusion in future. However, today I found that doing so caused me a problem. After renaming the file, and installing it, the installation failed with the error: " A network...(read more)

  • Understanding and developing web services

    - by Pankaj Upadhyay
    This question is in conjuction with How would you approach developing a Hotel Reservation System? The solution to a system with different interfaces(or clients i should say) is to go with developing a Web service and have other systems interact with it. I never had the requirement for developing a Web service so i am bit short on it. All i understand is that A web service is a system or application that performs some operations which may include modifying, sending or receiving data over a network using HTTP protocol. (Let me know if the understanding is wrong) Now, from the other question it's clearly understood that i need to develop a web service but i have no idea as to how should i go about it. My language of choice is C# and .NET Framework. Question:: How do we develop a webservice and which tools,technology and framework should i use for the same using C# language?? Question:: How can i interact with this from a desktop WPF application, Website and Mobile app

  • What is the economic rationale behind programmers who work on a open source project (free) instead of a commercial project (not free)?

    - by Kim Jong Woo
    I can't understand why some people dedicate so much hour into a completely open source project without closing it and yielding greater profit from it. I don't think profiting from your code is evil, I think it's a great motivator. Why do some people feel that commercial software and generating money from it is bad? There seems to be this black and white thinking that open source = good, commercial = bad. I hardly find this convincing, and often commercial companies which are supported by sales produce very good results. An open source software in the same niche can't compete against the corporation. Of course, sometimes this is completely the other way around where private companies produce inferior product compared to open source counterparts. So help me understand, why do programmers open source their code when there is commercial prospects for it? Shouldn't the rational programmer or human being make every effort to capitalize on their opportunity cost? Working on a open source project for months when you could've spent the same number of hours at commidity wage or some other monetary compensation?
