But Print button for full screen is work, <Alt>Print is not.

That because the key conflicts from Magic SysRq key in ubuntu10.10

Just disable it with these commands:
>sudo sysctl -w kernel.sysrq=0

change the configuration file to make it work after restart the computer:
>su root
>vi /etc/sysctl.conf
add this line:
kernel.sysrq=0


TCP capture:
>sudo apt-get install wireshark
Just use it to open the tcpdump data file.

>sudo apt-get install nethogs
