  - by JoshuaD

  What's the easiest way to share a calendar in outlook 2007 between 5-10 people on a local network? I have tried sharepoint and the password prompts are too much of a pain. Security is not an issue; ease and functionality are the priorities.

  What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong? EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

• Free or very Cheap VPN server software with high concurrent users count

  - by Martin KS

  I'm hoping to implement a VPN whereby about 200 concurrent users can log in to briefly access my network. I had a look at OpenVPN and this seemed excellent, but was hoping that there would be a less costly option on a per-concurrent-user basis. I've no need for particularly strong security, and my only other requirement is that I would need to be able to add users in bulk via csv or similar. Does anyone have any suggestions?

• Error handling pppd configuration?

  - by Sebastian

  I have a computer, running ubuntu, that I want to be connected to the network at all times. It has a GSM modem connected to it via USB. Is there some program available that monitors that the networking is working (by pinging some site(s)), and if not tries to fix the error by reseting the modem, reloading the USB drivers and perhaps by dropping the USB port's current (if possible) to force the modem to reset ?

I tried using the vpn connection tab under the network connections, but my files didn't specify a username after importing and it forced to me to save one, so attempting to connect to it didn't yield any results. What am I supposed to do with these four files to connect to the vpn?

How would you design the network, remote access, and configure the workstations? Thanks!

• a couple of questions about proxy server,vpn & how they works

  - by Q8Y

  I have a couple of questions that are related to security. Correct me if i'm wrong :) If I want to request something (ex: visiting www.google.com): my computer will request that then it will to the ISP then to my ISP proxy server that will take the request and act as a middle man in this situation ask for the site (www.google.com) and retrieve it then the proxy will send it back to me. I know that its being done like that. So, my question is that, in this situation my ISP knows everything and what I did request, and the proxy server is set by default (when I ask for an internet subscription). So, if I use here another proxy (lets assume that is a highly anonymous and my ISP can't detect my IP address from it), would I visit my ISP and then from my ISP it will redirect me to the new proxy server that I provide? Will it know that there is someone using another proxy? Or will it go to another network rather than my ISP? Because I didn't get the view clearly. This question is related to the first one. When I use a VPN, I know that VPN provides for me a tunneling, encryption and much more features that a proxy can't. So my data is travelling securely and my ISP can't know what I'm doing. But my questions are: From where is the tunneling started? Does it start after I visit the ISP network (since they are the one that are responsible for forwarding my data and requests)? If so, then not all my connection is tunneled in this way, there is a part that is not being tunneled. Since, every time I need to do anything I have to go to my ISP and ask to do that. Correct me if I misunderstand this. I know that VPN can let my computer be virtually in another place and access its resources (ex: be like in my office while I'm in my home. This is done via VPN). If I use a VPN service provider so that I can access the internet securely and without being monitored by my ISP. In this case, where is my encrypted data saved? Is it saved in my ISP or in the VPN service provider? If I use a VPN, does anyone on the internet know what I'm doing or who I am? Even the VPN service provider? Can they know me? I think they should know the person that is asking for this VPN service, am I right?

• Determine the percentage of a file that has been ftp'd from client to server

  - by klwillie

  I want to ftp a large file from a Windows client to a Windows server, using their IP addresses. This is on an internet independent network. While the file is transferring, I would like to determine how many bytes have been received by the server. I then would like to use this information to determine in real-time the percentage of the file that has been transferred to the server. Any recommendations as to the ftp command syntax and C# code to achieve this?

• dhcpd: How to tell how many leases are available?

  - by Jakobud

  I'm a little bit new to dhcpd. I'm trying to figure out how many leases we have available on our network. The /var/lib/dhcpd/dhcpd.leases file appears to show almost a history of leases and some of the current leases. Not sure if that really helps me or not... I figured there might be a command or something I'm unaware of that can tell me how many leases are left.

  Starting around the time I installed the Office 2010 Beta, Whenever I login, Windows tries to open a file named "Bob", coincidentally the first part of my username. Selecting Notepad to open it, and it contains TCP/IP network settings.

Is there any other place I should be looking for errant entries?

• Directly printing to remote CUPS/IPP server on Snow Leopard

  - by Martin v. Löwis

  I need to use Kerberos authentication when printing from my OSX machine, however, the machine itself does not have a service account in active directory, so the KDC will not issue a delegation ticket for the local CUPS installation. I think printing could work if the printing framework would directly print to the network CUPS server (or even to the Windows print server), bypassing the local CUPS. Is it possible to setup printing so that it directly accesses the remote print server? (asking for a service ticket for that server would succeed)

• OS X - forwarding external port to local loopback address

  - by Rory Fitzpatrick

  I have an HTTP service bound to port 8000 that I want to access from another computing on the network, but I can't seem to connect using the external IP address of the machine (e.g. 192.168.0.105). I've checked the OS X firewall isn't running, so I'm assuming the issue is the service is only bound to the IP address 127.0.0.1, and not the external IP address. What would be the easiest way to temporarily forward external connections on port 8000 to 127.0.0.1:8000?

• How can I make my other computer run a program?

  - by TimothyAWiseman

  If I have two computers, both running Windows 7, on my home network, is there some way to write a script so that I can click on a single icon on the one computer and make the other computer execute a program? Clearly, I could do this by accessing the other computer through remote desktop connection and then executing the program, but I would like to avoid (or at least automate) making the connection so I can just click a single icon to have it happen.
