Ubuntu displays the NIC packet processing speed and ubuntu Packet
View Nic packet processing speed in ubuntu

sar -l 1 10

First, install sar. The "-l" parameter in the apt-get install atsarsar command is net-interf (general). The parameter "1" is counted every second, the "10" parameter indicates the total number of times.

Q: How can I view the network speed of two NICs in a PC under ubuntu?

Install an indicator-multiload

Sudo add-apt-repository ppa: indicator-multiload/stable-daily
Sudo apt-get update
Sudo apt-get install indicator-multiload
 
Ubuntu Nic configuration problems (urgent)

Root permission is required to set the NIC

Sudo ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up
It is shown here.

Supplement:
The ip address is not displayed because your local Nic does not obtain the ip address.
