How do you enable LAN card Ethernet - eth0 in Linux?
ifconfig eth0 up
How would a technician permanently change the IP address of an Ethernet card on a Red Hat Linux PC?
Command to change the IP address on Linux is ifconfig.Run ifconfig to find the interface name for the connected Ethernet card. If there is only on ethernet card present on your system then the interface name would be eth0. If there are more than one Ethernet cards present on your machine then they interface names will be ethn.Once you have figurred out the interface name then ifconfig command can be used to modify the IP address$ ifconfig eth0 upeg$ ifconfig eth0 192.168.1.100 upWould assign new IP address to eth0
How do you release and renew your ip address in Linux computer?
Below are two different methods of how this can be done at the command line. ifconfig eth0 downRunning the above command would take the eth0 interface (the first network card) down. Which is the same as releasing the IP address from that network card.ifconfig eth0 upAfter the interface is taken down, typing in the above command would bring that interface back up.ordhclient eth0Renews the IP address assigned to it by DHCP.
Are network interfaces named sequentially in Linux?
Yes. The first configured interface is eth0, the second eth1, the third eth2, and so on.
In Linux what does 'iwconfig eth0 key 5c00951b22' do?
It sets the WEP key that will be used by that interface. Answer: Network + Guide to Networking Fifth Edition, Chapter 8. On your Linux workstation, you open a terminal window and type at the command prompt iwconfig eth0 key 5c00951b22. What have you done? C. Established the credentials the wireless interface will use to communicate securely with the access point.
How do you set the IP address in Linux?
set the IP address with the ifconfig command use the syntax: ifconfig interface address netmask up view your network interfaces with the command ifconfig then for example to set address to 172.12.0.1 on the interface eth0 use: ifconfig eth0 172.12.0.1 netmask 255.255.0.0 up make sure you have root permissions to do this, either be logged in as root or preceed the command with "sudo". you don't have to specify the subnet mask if you don't want to, but it is generally recommended to do so.
How do you change your IP address in Linux?
If your router assigns IP addresses via DHCP, it is better to configure the router to pre-assign IP addresses to certain hostnames.If you do not have a DHCP server running in your router, you can specify an IP address for a network interface with the ifconfig command. For example:ifconfig eth0 192.168.20.10
How do you set IP Address of a LAN card in Linux?
Assuming you're not using DHCP (in which case it would be set automatically), you would use:ifconfig eth0 10.10.0.1substituting the correct interface card and IP address, of course.
What should you do if eth0 is not present in Red Hat Linux?
If the hardware is present, but operating system can not use it, then mostly the problem is a lack of drivers for that specific hardware. Upgrading kernel or downloading and compiling drivers, if released, would help that.
On your Linux workstation you open a terminal window and type at the command prompt iwconfig eth0 key 5c00951b22 what have you done?

How do you find your IP address in Linux?
Via the command line, type: /sbin/ifconfig By default, it will show every network device. Since many Linux systems use eth0 as the default network device, you can optionally type the following to view just that one: /sbin/ifconfig eth0 Under each network device will be 'inet addr' or 'inet6 addr' depending on how you've configured your system. Next to it is the IP address. If you're connected via LAN or router you may want to find your external (public IP). It could be done simply from command-line as: curl smart-ip.net/myip
How do you connect to the Internet in Linux?
ifconfig is he command common to all Linux distrobutions. In order to use it, you have to know in advance what your IP information should be. To set your ip address to 192.168.1.100, with a standard class C netmask you would do this: ifconfig eth0 192.168.1.100 If you have a DHCP server installed in your network, or if your home router has a DHCP server, you should use a DHCP client to connect to the network. There are two common DHCP clients. dhclient, and dhcpcd. Their usage is mostly the same: dhcpcd eth0 or dhclient eth0 The methods described above will work on any distribution, but as you can see it requires you to manually type commands every time. You will have to check with your distrobution to get specific instructions, but most distributions have a 'network manager' that does that sort of thing for you. In Ubuntu, you can just click on the network manager icon and select Wired Network or pick a wireless network. On Slackware, you can type netconfig at the command line and it will walk you through setup of a wired network. Setup of wireless networks in Slackware can be tricky if you don't have a network manager installed. The best thing to do would be to Google the name of your distribution and network or internet.
