Networking in Redhat linux 6

[decentandsimple]

Hi All,

Previously Red Hat System 5 was installed in my system recently got downloaded Red hat 6 ISO and installed. The occurrence is really good. But even My Lan is inserted in the jack panel but the icon of Cross on network is showing. Found that the lan card detected was some different company. How to detect the Lan Card in Linux

I'm not exactly sure what you mean by "Cross", but to answer your question, there are several things you can do to interrogate your system to get network adapter info.

# show devices attached to PCI bus

lspci

# show network adapters (real, loopback, virtual, etc.) that have kernel drivers installed

ls /sys/class/net

# get the driver for a particular device

ethtool -i eth0

# check if a physical link is detected for a particular device

ethtool eth0|grep Link

# get current tcp/ip configuration

ip a

# get routing info

route -n

# get DNS settings

cat /etc/resolv.conf

# get tcp/ip configuration

grep -H . /etc/sysconfig/network-scripts/ifcfg-eth*
