For using a user friendly GUI to handle your UMTS Modem in Gnome you can use the Gnome-PPP. In the background Gnome-PPP uses WvDial to talk with the modem.
All what you need to install is:
-pppd
-WvDial
-Gnome-PPP

Enjoy it!

Tomato is a great firmware for wlan routers. I am using it on any Linksys WRT54GL 1.1 and it's working great!

There are a lot of features like bandwith monitoring, VLANs, QoS, DDNS and so on. The bandwih monitor is a great tool, because you have a overview about the traffic in live mode and also in daily, weekly and monthly graphs.

But for more information have a look at the vendor page.

If you have the problem that the system clock in the virtual machines are running faster then the host based system clock, you have to do the following steps for solving it.

-open the file with root privileges

/etc/vmware/config

-if these lines are not there add this lines above otherwise change it (where 2200000 means your host CPU frequency in kHz)

host.cpukHz = 2200000
host.noTSC = TRUE
ptsc.noTSC = TRUE

-save the changes and restart the vmware services

/etc/init.d/vmware restart

-now the clocks should run perfectly

For using the whole 4GB of RAM on a Ubuntu system you just have to install the two following packages:
-linux-server
-linux-header-server
that's all :-)

...when you want to mount a USB device (e.g. USB HDD) over the VMware server console installed on a Linux machine and the menu is empty, that should be the same problem as mine.

The solution is to open the following file...

vi /etc/init.d/mountdevsubfs.sh

...and comment out the 4 lines...

#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb

Now you have to restart the mountdevusbds.sh and that's it!

EDIT:
If the problem exists again after a reboot, then add the following line in your /etc/fstab

usbfs 		/proc/bus/usb 	usbfs auto 0 0
