Hotmail Spam blocker going crazy against IP addresses

It seems that Hotmail spam filter is going mad, they decided to block email from IP addresses, it just happen for my company this week and we thought that we will have to invest to upgrade everything, as hotmail had block the IP of our server saying that Spam were going from this IP, this was a big chock for us!

Then this happen again with my personal account, see message below.

After having created spam with their own system (hotmail) they are blocking server IPs which they think are copying them !!! (they want to keep their copyright... :)

I wouldn't like to be have an Hotmail account right now, receive no genuine email any more because the master called Ms decided to do so....

I just hope that they fix it soon before I loose my friends :)

Remote desktop to windows XP

Hey!! I have just managed to run remote desktop from ubuntu 7.10 to windows XP through a VPN.

First I needed to install the following packages or plug-in to the network manager

  • "pptpd" and "pptp-linux", pptpd is the microsoft protocol for Point to point Tunneling protocol, this plug in to the network manager will allow to to set up the vpn client.
  • vpnc plug in to the network manager will allow to start the connection and the connection.

Fig: The network Manager with Vpn plug-in

This install can be done easily using the synaptic Package Manager

once install you can establish the vpn connection and it will be ready for the remote desktop. On the option choose RDP or RDPv5 also filling the IP address of your Windows XP box.

The only problem I got now is my slow and unreliable broadband connection.
I have a poor 500K/s with talk talk, I should go back to BT but the price is double.
I wish I were in Paris with a fibre to the home connection....

Extra note:
If you want to VNC to an old windows machine such as windows 2000, windows 95/98:
TightVNC as the server on window and the "Terminal Server Client" (using VNC for the protocol option) on the remote linux box works perfectly.
