    RE: Transition from Windows-based network to Linux-bas
    [quote]By Virtual Terminal Solution I am referring to the capability to launch and application on a remote server that is streamed to your desktops by selecting a seemingly local applications on your computer. An example would be to see a quickbooks icon on your computer, when you launch it it would call out through lets say a citrix application to your citrix server telling the server to launch the application but display the windows and all output on your local computer. By using this solution you can roll out OS specific or mission critical applications to all users through a secure channel from a single system to users on all operating systems. By using citrix or another virtual terminal framework the users only see the windows from the specific application rather than having complete access to the desktop and all applications on the remote server.[/quote] What are good applications for that? Are there any free (or cheap) ones? Would I be able to have several clients running remote applications (perhaps the same application) simultaneously?

    [quote]What about Exchange and your current Outlook clients ? Are they using "basic" email features: sending/receiving emails and few more, or are they using "enhanced" features ( shared calendars, agendas, multiple email folder, public folders) and so on ? I'm absolutely a supporter of Linux platforms but there's so much to do to have a real working environment if you want to replace a Windows Server system on certain enterprise companies.[/quote] I am not using an Exchange server, the clients are using Outlook to connect to Google Apps account. They mainly use email and the calendars so it shouldn't be an issue to transfer to Thunderbird. [quote]x11 app forwarding can be done through ssh, but you cannot forward the gui from windows based applications via ssh. Using local virtual machines would fulfill their needs, but it can become costly and can be abused by the users, which is why I recommend virtual terminal sessions. The price of a single instance of an OS and software along with a virtual terminal solution can be quite a bit cheaper and more secure.[/quote] What do you mean a virtual terminal solution? Will it run on the server and be accessed remotely by the clients?

    Transition from Windows-based network to Linux-bas
    I am looking to make the switch from a Windows based network to a Linux (preferably Ubuntu, because I used it the most) based one. Currently the network includes a Windows 2003 server which acts as a domain controller and file server, a network shared printer (Canon 2300N) and 7 clients running Windows. Several other Windows-based clients connect remotely via RDP. I would like to setup a server to act as a domain controller, file server, and (if possible) terminal server. The clients should be authenticated via the server and have access to the files stored on it (via ssh?). Here are several points that I was wondering about: [li]All the clients use Outlook, some of the clients run Quickbooks Pro and another program called Tentant File Pro. I was thinking about replacing Outlook with Thunderbird (I contact, calendar, and tasks) and I know that Wine can't run Quickbooks and Tenant File Pro so I may have to use VirtualBox/VMWare because these applications can't be replaced by native Linux versions.[/li] [li]I need an adequate backup solution for the files on the server running as a daily backup.[/li] [li]Should I use webmin to administer the server?[/li] [li]What antivirus / firewall solution should I use for the server and the clients?[/li] [li]How can I allow remote clients the login to the server to be able to run applications (Outlook, Browser, Tenant File Pro, etc.) remotely on the server?[/li] What is the best solution for this? And what would be the least painful way of making the transition for the users? I know this is a lot, but any feedback would be appreciated. Thanks.

    [li]I need an adequate backup solution for the files on the server running as a daily backup.[/li]
    [li]Should I use webmin to administer the server?[/li]
    [li]What antivirus / firewall solution should I use for the server and the clients?[/li]
    [li]How can I allow remote clients the login to the server to be able to run applications (Outlook, Browser, Tenant File Pro, etc.) remotely on the server?[/li]

    What is the best solution for this? And what would be the least painful way of making the transition for the users?


    I know this is a lot, but any feedback would be appreciated.

    Thanks.
