• software to emulate a blackboard over internet

  - by Abhijith Madhav

  I need to tutor my brother on a particular topic. We live in different geographical areas. We use g-talk to do the same. We do not have web-cam's to enable video chat. The tutoring will involve a lot of off-the-cuff illustrations. I am hence searching for a suitable software which will emulate a blackboard over an internet connection. I need the software to enable sharing of a common canvas on which I can draw, write and point to. Say a Microsoft paint canvas on internet. Could you point out a suitable software? Google is not of being help at the moment as I suspect that I am not specifying my search criteria properly.

• Is there a usable HTML web gallery template for Lightroom 2?

  - by Johannes Rössel

  The built-in HTML gallery unfortunately generates invalid HTML markup so its looks are likely more coincidence than proper design. That aside its JavaScript usage prevents using the middle mouse button to open an image in a new tab. A look at the few free HTML gallery templates out there shows me that there seems to be little interest in building an actual HTML gallery which doesn't use JavaScript. Most of them are using JS to build fancy animations or in-page popup boxes containing the image. This may be nice for some people but at least one person who looks at my images is on dial-up and quickly opening all images in individual tabs to let them load and then close the connection is very nice to have there. Anyone seen such a gallery template; i. e. simple, plain HTML without JS? My HTML/CSS skills aren't that good that I can develop such a thing on my own, unfortunately.

• Ubuntu 12.04 MySQL 5.5 MyODBC 5.1 or 3.1 query hangs

  - by jorgearr

  I have been able to install Ubuntu 12.04 with LAMP MySQL version 5.5.x It works fine within linux, it allows me to connect from myodbc windows vista or windows 7 I have configured networking access and have been able to access from windows vista using putty and other tcp connections like mysql query browser. I have also configured or disabled ufw firewall and apparmor. The connection works fine until I query data from the tables. It lets me query small amounts of data like: SELECT name FROM users limit 20 but if I do a SELECT * FROM users, it goes on a never-ending loop. This happens even on tables with very few records like 5 or even less. The problems occur with windows because I tried ssh from linux mint and it worked fine. I need to be able to work using MyODBC either 3.51 or 5.1 since my client program is made in VB6 and connects to mysql server via tcp/ip. The server is an HP PROLIANT ML350G6 with Intel Xeon 64 bits. I tried several ubuntu server version (12.04 64bit, 10.10 64bit, 11.04 32bit) and none has worked I even tried CentOS 6.3 and the same. As a reference, it works fine with onother ubuntu server version 6.x on HP Proliant 150 and mysql 5.0.x that is like 7 years old and never updated. Help Please.

• Stunnel too many clients

  - by davidsmalley

  I'm trying to hook up stunnel and haproxy to forward https connections through to some backend servers. I've got haproxy setup right, and I seem to have stunnel set up right. Trouble is that when I hit the setup with a load test after a while I start to see these log entries: 2010.05.05 11:24:43 LOG7[3498:3086792368]: https accepted FD=512 from 10.195.158.225:52579 2010.05.05 11:24:43 LOG4[3498:3086792368]: Connection rejected: too many clients (=500) I guess I've hit a limit somewhere but I wasn't sure how to fix it, there doesn't seem to be a config file option for stunnel to change this. Does anyone know how to configure stunnel for a potentially large number of connections?

• Can't complete dropbox installation from behind proxy in Ubuntu 11.10

  - by Mark Jones

  Problem: My PC on campus sits behind a proxy (requiring authentication) and I can't setup Dropbox. I am convinced that this is a proxy issue as I can't setup Ubuntu one either (but I don't use Ubuntu One so that is not a problem). I have looked at the Ubuntu One fix but it seems to be to modify settings explicitly related to Ubuntu One. I can install the nautilus-dropbox package (compiled from source and from .deb package from website and from software centre) but once I click OK from the "Dropbox Installation" dialog box (prompting me to download the proprietary daemon) the installation just freezes with the OK button pressed. When I look at its process in System Monitor its waiting channel is inet_wait_for_connect. I have set the following proxy directives thus far: Added mj22:**@proxy.waikato.ac.nz:80 information to network proxy settings under network in settings. Added http_host and http_port variables under gconf-editor-system-proxy Added 'host', 'authentication_password' 'authentication_user' and ticked 'user authentication' and 'use_http_proxy' under gconf-editor-system-http_proxy Added export http_proxy="http://mj22:**@proxy.waikato.ac.nz:80/" to /etc/bash.bashrc Added Acquire::http::proxy "http://mj22:**@proxy.waikato.ac.nz:80/"; to /etc/apt/apt.conf (which is what I imagine is letting Software Center retrieve packages). (where ** is my password) I have also added the equivalent ftp and https lines for the above entries. I get the internet fine and Software Centre can download packages but thats it. Related issues: The software centre can't fetch reviews (but can download packages). When trying to add an online account in Gnome 3 a dialog pop up appears with "Error getting a Request Token: Cannot connect to proxy (proxy.waikato.ac.nz)" Updates: After some time (10mins ish) Dropbox shows an error dialog box that reads: Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set you http_proxy environment variable. Is there a way I can see what environment variables are currently set?

• failing to achive tunneling to fresh ubuntu 10.04 server

• Multiple monitors showing same screen but different resolutions

  - by Luis Alvarado

  Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

• Implementing the transport layer for a SIP UAC

  - by Jonathan Henson

  I have a somewhat simple, but specific, question about implementing the transport layer for a SIP UAC. Do I expect the response to a request on the same socket that I sent the request on, or do I let the UDP or TCP listener pick up the response and then route it to the correct transaction from there? The RFC does not seem to say anything on the matter. It seems that especially using UDP, which is connection-less, that I should just let the listeners pick up the response, but that seems sort of counter intuitive. Particularly, I have seen plenty of UAC implementations which do not depend on having a Listener in the transport layer. Also, most implementations I have looked at do not have the UAS receiving loop responding on the socket at all. This would tend to indicate that the client should not be expecting a reply on the socket that it sent the request on. For clarification: Suppose my transport layer consists of the following elements: TCPClient (Sends Requests for a UAC via TCP) UDPClient (Sends Requests for a UAC vid UDP) TCPSever (Loop receiving Requests and dispatching to transaction layer via TCP) UDPServer (Loop receiving Requests and dispatching to transaction layer via UDP) Obviously, the *Client sends my Requests. The question is, what receives the Response? The *Client waiting on a recv or recvfrom call on the socket it used to send the request, or the *Server? Conversely, the *Server receives my requests, What sends the Response? The *Client? doesn't this break the roles of each member a bit?

• How to set up a wireless AP with a linux box and SOCKS proxy

  - by user50455

  I've got: (1) Linux box (Arch linux to be precise, but that doesn't really matter) (2) Ethernet connection on it (say, eth0) (3) Socks proxy on a remote site (say, remote :port), which can be accessed through (2) (4) Wireless card on local linux box (say, eth1) So, the task is: create a wireless access point using (4) on local site (1) in such a way that all connections from it will go through proxy (3). E.g., when one simply connects to that AP (well, there should be DHCP or something for that) and goes to serverfault.com, all the traffic goes through that SOCKS proxy. I'm just asking for the digging direction and some references, not step-by-step tutorial. Thanks in advance

• Speeding up remote X sessions

  - by Alexander Gladysh

  I have a remote machine running Ubuntu 11.10 Server, to which I connect via SSH from OS X 10.7.3: Host remote.example.com ForwardX11 yes ForwardX11Trusted yes Sometimes I want to launch a GUI application there (most notably, gitk). But UI is rather slow. Both remote machine and my own Mac have good internet connection. Ping between them is about 55ms, and there is no packet loss. Is there something I can do to speed things up? Setting up some other remote desktop solution is an option, but I'd like to avoid it since I don't need this application very often.

• Configuring vsftpd with nginx on ubuntu

  - by arby

  I have vsftpd installed on Ubuntu 12.04LTS along with nginx, php, and sql on an Amazon ec2 instance. The web server is good to go, but I'm having trouble connecting to the FTP server. I'm not quite sure how to set the privileges or what configuration options I might be missing. By default, the location of the web root is at /usr/share/nginx/www and it is owned by root:root. The web server runs as user www-data in the group www-data. I've opened port 21 and set the passive ports in the ec2 backend and ufw firewall. In vsftpd.conf, I have: ... anonymous_enable=NO local_enable=YES local_umask=0027 chroot_local_user=YES pasv_enable=YES pas_max_port=12100 pasv_min_port=12000 port_enable=YES ... Now, I'm unsure how to create the FTP user that when I login, displays my web directory with write access. I've tried it a few different ways, but I keep running into errors (either no connection, no write access, or very slow timeouts.)

• Beginners Guide to Client Application Services

  - by mbcrump

  What is it? Client application services make it easy for you to create Windows-based applications that use the ASP.NET AJAX login, roles, and profile application services included in the Microsoft ASP.NET 2.0 AJAX Extensions. These services enable multiple Web and Windows-based applications to share user information and user-management functionality from a single server.   What can you do with it? Authenticate a user. You can use the authentication service to verify a user's identity. Determine the role or roles of an authenticated user. You can use the roles service to change the user interface of your application depending on the user's role. For example, you can provide additional features for users who are in an administrator role. Store and access per-user application settings located on the server. You can use the Web settings service (also known as the profile service) to share settings across multiple applications and locations. Client application services take advantage of the Web services extensibility model through client service providers that you can specify in your application configuration files. These service providers include offline functionality that uses a local cache for authentication, roles, and settings data when a network connection is unavailable. Give me an example of where I would use this! Sharing login and user role information between a Windows Form application and a ASP.NET application. How do I configure it? Click Here

• How to set Brocade 200E SAN Fabric Switch Port Health Monitoring to "monitored"

  - by Kenny

  Hi, I have a Brocade SAN Fabric Switch, a 200E. When using the web based management interface "SwitchExplorer" I can click the port, and I see "Port Administration Services". In the first screen of data that appreas, there's a row called "Health" which has value "Unmonitored". Do you know how to set this port to be Monitored? And if also - what "Health" monitoring does? I'm hoping it'll email or log if there's a connection or disconnection.. Many thanks for looking... Kenny

• Citrix Access Gateway not redirecting to login URL

  - by Dave

  We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

• Squid traffic tunneled through VPN

  - by NerdyNick

  So what I'm trying to do is have a Squid Proxy run on 1 machine along side a VPN connection. What I want to happen is all traffic running though the Squad Proxy would run though the VPN for its outbound. ie Desktop - (Squid Proxy - VPN) The goal is to allow my desktop selective tunneling through the VPN. So that Instant Messaging and the like that do not need to run through the VPN can go through my normal traffic. Typically I would go though a SSH Proxy but currently am forced to use VPN to gain entry into the office, and a Squid proxy seemed like it might work out the easiest for what I am needing. EDIT Realize I forgot to actually state what problem I'm running into. I have the Squid setup and verified it works, but once I connect to the VPN. All requests to Squid get accepted but Squid is unable to make the request over the VPN. So the client ends up just sitting there.

• netsh wlan add profile not imported passphrase

  - by sirlancelot

  I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings?

• Wireless technology - which is better: more single radio APs or less dual radio APs?

  - by gert_78

  We are currently talking to vendors of wireless solutions for a wireless deployment in a university campus with some 5000 students. One vendor is offering us a Cisco solution with a WLC 5508 controller and 69 2x2 MIMO Dual-band/Dual radio APs (Aironet AP 1042 model) The other vendor is offering us an Aruba solution with a 3600 controller and 96 2x2 MIMO dual band BUT single radio APs (Aruba AP93) Both vendors are charging 82.000 US$ (support, 3y service contracts, switches and additional required options all included of course) The Aruba vendor is trying to convince me that 96 single radio APs will give us more connection/users/capacity then the 69 dual radio APs. I have my doubts about that and since it is my core competence-domain I wanted to ask here the opinion of people that have a more profound knowledge and experience in this area. When you talk to vendors it's often hard to get objective information. So try to answer only if you are sure and please mention it if you are affiliated with one of the vendors. I appreciate all useful help and want to thank you in advance for the effort!

• [SOLVED]Need help with remote dekstop - Limit the computers you can access server from

  - by stirredo

  I have a windows server 2003 computer that is accessed by remote desktop connection. To access the server all you need to know is the IP address of the computer. I want to limit the computers that can access the windows server computer to authorized computers only. The authorized computers won't have static IPs, so I cannot limit them on basis of IP address. Can I limit them on basis of MAC id perhaps? I won't mind using third party solution like Teamviewer or Logmein etc. So How can I solve this problem? EDIT: Found a possible solution in team viewer. Team viewer creates a unique partner ID for the computer it is installed on. It has an option for allowing only authorized partner IDs to access the computer. Problem solved.

• Using Remote Desktop, connect to a Windows 7 domain user account without first logging on locally?

  - by Robert S Ciaccio

  I have a dell laptop (henceforth we'll call this the server) running Windows 7 Enterprise. The server is part of my company's domain. My primary user account is a domain account. When I am at home and not connected to the domain, I prefer to connect to the server using Remote Desktop Connection from my MacBook Pro (we'll call this the client). The problem is, that if I do not physically login to the server, I am unable to connect to it using RDC from the client. I have a local administrator account on the server, and connecting to it via RDC works just fine. I had a feeling that the Mac RDC application was not giving me the full story, so I attempted the same procedure from a Windows 7 client. When trying to login, I get this message: So basically, If I logon to the server physically with my domain user and lock the computer, I can then successfully logon from the client. Otherwise, I am unable to connect.

  When I go to certain websites that have google analytics, they never load up. One example is www.jquery.com. I tried in firefox, chrome, safari and explorer. Chrome & safari, flash the home page then it disappears and the screen goes white. Firefox never loads anything and the spinner just keeps spinning. Loads fine in explorer. Any ideas of what may be going on? If I use my laptop, on my same home internet connection, it works fine. This is not happening on all sites with analytics, just certain ones.

• JUnit Testing in Multithread Application

  - by e2bady

  This is a problem me and my team faces in almost all of the projects. Testing certain parts of the application with JUnit is not easy and you need to start early and to stick to it, but that's not the question I'm asking. The actual problem is that with n-Threads, locking, possible exceptions within the threads and shared objects the task of testing is not as simple as testing the class, but testing them under endless possible situations within threading. To be more precise, let me tell you about the design of one of our applications: When a user makes a request several threads are started that each analyse a part of the data to complete the analysis, these threads run a certain time depending on the size of the chunk of data (which are endless and of uncertain quality) to analyse, or they may fail if the data was insufficient/lacking quality. After each completed its analysis they call upon a handler which decides after each thread terminates if the collected analysis-data is sufficient to deliver an answer to the request. All of these analysers share certain parts of the applications (some parts because the instances are very big and only a certain number can be loaded into memory and those instances are reusable, some parts because they have a standing connection, where connecting takes time, ex.gr. sql connections) so locking is very common (done with reentrant-locks). While the applications runs very efficient and fast, it's not very easy to test it under real-world conditions. What we do right now is test each class and it's predefined conditions, but there are no automated tests for interlocking and synchronization, which in my opionion is not very good for quality insurances. Given this example how would you handle testing the threading, interlocking and synchronization?
