how to check the network status.?

[Khairul_09]

Hi guys,

I’m a beginner in Linux. Just want to know what is the cmd to ping/check the link speed or something like Network Info. If for server checking (Show information CPI info) is (cat /proc/cpuinfo ) (correct me if im wrong)

Thanks,

ifconfig <interface name > should give you all the info u need

You can use the ping command in Linux as you would on any other platform. For the rest you can use ifconfig as mentioned and if you have NetworkManager running you can use that to check link information too.

If you're looking for info about the supported link speeds, the negotiated speed, and whether the link is up, the ethtool command supports most NIC's. It's included in many distro's but if not, you may need to install it.

ethtool eth0
Settings for eth0:
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full
