[Netlantis] Routing Table Geoanalysis

Today is the official launch of my latest (and newest) project, the Routing Table Geoanalysis.

In fact, while I was working on the ASGEO project I received an invitation to participate to a visualization competition, NetSci07, with my (now old) rootzmap project... which I did (though I did not win :)).

This is when came to me the idea of creating Geoanalysis posters... and the Netlantis Routing Table Geoanalysis project was born. Of course, this will be part of the Netlantis project (when it's back), so every peer will have its own RTG poster available for download every month.

ps: Note that the rootzmap project will also be available from Netlantis so peers will be available to generate their own map (which is going to make nice t-shirts for your-favorite-NOG meeting) :)

[SYSCTL] Cable Bandwidth Upgrade

No need to say that it works better than before (4Mb/s - 256Kb/s).

Yumm, since October, upload has been upgraded to 1Mb/s...

[SYSCTL] Installing VMXnet on Debian Etch (4.0)

# Getting the right packages if using a netinst (with a 2.6.18-4-686 kernel)
apt-get install linux-kernel-headers linux-headers-2.6.18-4-686 make psmisc gcc

# Creating a symlink so that the vmware script finds everything easily
cd /usr/src && ln -s linux-headers-2.6.18-4-686 linux

# Installing VMWare Tools (no SSH, console only)
(Answer "no" to the vmhgfs question, so that you won't build it (it's useless in most cases))

# the vmxnet module is compiled...

# Now we're doing what they are telling us to do...
/etc/init.d/networking stop
rmmod pcnet32
rmmod vmxnet
depmod -a
modprobe vmxnet
Don't /etc/init.d/networking start ... it's useless

# And this is what they are not telling us to do :
Stop the VMWare...
Edit "Other Linux 2.6.x kernel.vmx" (or whatever .vmx you have) :
Add the following line under ethernet0.present = "TRUE" :
ethernet0.virtualDev = "vmxnet"

Reboot the Linux, lspci and lsmod will show you no pcnet32 device, only the vmxnet one.
