LAN messaging with XMPP protocol (jabber) to chat or to copy and paste links and texts in rdp sessions
Here is how I satisfied my need to have a LAN messaging program, not really to chat with other users on the same LAN, which I could do, but to copy and paste links or texts between a rdp client and a rdp server when copy and paste from/to clipboard does not work in rdp sessions, for instance with some Android rdp clients.
These are the programs I used:
- Openfire 3.9.3 on the "server" (which can be a simple Windows pc): a realtime collaboration server using XMPP/Jabber
- Miranda IM 0.10.23.0: a multi-protocol instant messaging client
- Xabber 0.9.30b: an Android Jabber client
Create a VPN to connect from an Android client to a home Windows XP server
If you want to connect to your home computer using rdp when you are not home and are connected to the internet, you have to open a port on your firewall; changing the standard rdp port on both your server and your firewall increases your security (or decreases your unsecurity); configuring a Virtual Private Network (VPN) increases your security even more, and you can close the rdp port on your firewall: in fact, when you connect your remote client to your vpn, your remote client comes inside your LAN so that you can remote access your server from inside the LAN.
- Configure server to create a VPN
- Configure router firewall for VPN passthrough
- Configure VPN on Windows clients
- Configure VPN on Android devices
Mounting a second fan on the back of the case (Antec SLK3000B)
With the summer approaching, I am making some experiments trying to cool my pc as much as possible while keeping it quiet. Now, airflow in the case is made by 2 fans: the intake fan, a Papst 4412 F/2GLL, pulls air inside the case from the front, the exhaust fan, a Antec Tricool coming with the SLK3000B, pushes air out to the back; in addition, the psu fan pulls air from the top of the motherboard through the psu to the back.
Since I bought a second Papst 4412 F/2GLL, I tried positioning this fan in different locations to see which one conributes the best to the cooling. One of these is the back of the case, in the bottom, where there would be additional cards: it pushes air out of the case through the back slots.
