It is used to view and change the configuration of the network interfaces on your system.Running the ifconfig command with no arguments, like this:ifconfig...will display information about all network interfaces currently in operation. The output will resemble the following:eth0 Link encap:Ethernet HWaddr 09:00:12:90:e3:e5 inet addr:192.168.1.29 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe70:e3f5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:54071 errors:1 dropped:0 overruns:0 frame:0 TX packets:48515 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22009423 (20.9 MiB) TX bytes:25690847 (24.5 MiB) Interrupt:10 Base address:0xd020 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:83 errors:0 dropped:0 overruns:0 frame:0 TX packets:83 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7766 (7.5 KiB) TX bytes:7766 (7.5 KiB) wlan0 Link encap:Ethernet HWaddr 58:a2:c2:93:27:36 inet addr:192.168.1.64 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::6aa3:c4ff:fe93:4746/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:436968 errors:0 dropped:0 overruns:0 frame:0 TX packets:364103 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:115886055 (110.5 MiB) TX bytes:83286188 (79.4 MiB)Here, eth0, lo and wlan0 are the names of the active network interfaces on the system.eth0 is the first ethernet interface. (Additional ethernet interfaces would be namedeth1, eth2, etc.) This type of interface is usually a NIC connected to the network by a category 5 cable.lo is the loopback interface. This is a special network interface that the system uses to communicate with itself.wlan0 is the name of the first wireless network interface on the system. Additional wireless interfaces would be named wlan1, wlan2, etc.These are the traditional naming conventions for network interfaces under Linux; other operating systems may have different names. For instance, under many BSD operating systems, ethernet interfaces are named em0, em1, etc. Check your configuration, or consult your documentation, to determine the exact names of your own interfaces.Viewing The Configuration Of All InterfacesIf you'd like to view the configuration of all network interfaces on the system (not just the ones that are currently active), you can specify the -a option, like this:ifconfig -aThis will produce output similar to simply running ifconfig, but if there are any inactive interfaces on the system, their configuration will also be displayed.Viewing The Configuration Of A Specific InterfaceTo view the configuration of a specific interface, specify its name as an option. For instance,ifconfig eth0...will display the configuration of device eth0 only.Enabling And Disabling An InterfaceWhen a network interface is active, it is able to send and receive data; when it is inactive, it is not able to transmit or receive. You can use ifconfig to change the status of a network interface from inactive to active, or vice-versa.To enable an inactive interface, provide ifconfig with the interface name followed by the keyword up.Enabling or disabling a device requires superuser permissions, so you will either have to be logged in as root, or prefix your command with sudo to run it with superuser privileges.For instance, if network interface eth1 is inactive, you can activate it with the command:sudo ifconfig eth1 upSimilarly, you can disable an active network interface using the down keyword. For instance, to disable the wireless network interface wlan0, use the command:sudo ifconfig wlan0 downConfiguring An Interfaceifconfig can be used at the command line to configure (or re-configure) a network interface. This is often unnecessary, since this configuration is typically handled by a script when you boot the system. If you'd like to do so manually, you will need superuser privileges, so we'll use sudo again when running these commands.To assign a static IP address to an interface, specify the interface name and the IP address. For example, to assign the IP address 69.72.169.1 to the interface wlan0, use the command:sudo ifconfig wlan0 69.72.169.1To assign a network mask to an interface, use the keyword netmask and the netmask address. For instance, to configure the interface eth1 to use a network mask of255.255.255.0, the command would be:sudo ifconfig eth1 netmask 255.255.255.0To assign a broadcast address to an interface, use the keyword broadcast and the broadcast address. For instance, to configure the interface wlan1 to use a broadcast address of 172.16.25.98, the command would be:sudo ifconfig wlan1 broadcast 172.16.25.98These configurations can combined in a single command. For instance, to configure interface eth0 to use the static IP address 192.168.2.5, the network mask255.255.255.0, and the broadcast address 192.168.2.7, the command would be:sudo ifconfig eth0 192.168.2.5 netmask 255.255.255.0 broadcast 192.168.2.7These are the most commonly-used configuration options for ifconfig. A complete list is provided below.What About DHCP?ifconfig can only assign a static IP address to a network interface. If you want to assign a dynamic IP address using DHCP, you should use the dhclient command.ifconfig syntaxifconfig [-v] [-a] [-s] [interface]ifconfig [-v] interface [aftype] options | address ...Technical Descriptionifconfig is used to configure the system's kernel-resident network interfaces. It is used at boot time to set up interfaces as necessary. After that, it is usually only needed whendebugging, or when system tuning is needed.If no arguments are given, ifconfig displays the status of the system's active interfaces.If a single interface argument is given, it displays the status of the given interface only.If a single -a argument is given, it displays the status of all interfaces, even those that are "down" (inactive).In all other cases, ifconfig configures an interface according to the options provided.About Address FamiliesIf the first argument after the interface name is recognized as the name of a supported address family, that address family is used for decoding and displaying all protocoladdresses. Currently supported address families include inet (TCP/IP; this is the default), inet6 (IPv6), ax25 (AMPR Packet Radio), ddp (Appletalk Phase 2), ipx (NovellIPX) and netrom (AMPR Packet radio).Options-aDisplay information for all network interfaces, even if they are down.-sDisplay a short list in a format identical to the command "netstat -i".-vVerbose mode; display additional information for certain error conditions.interfaceThe name of the interface. This is usually a driver name followed by a unit number, for example "eth0" for the first Ethernet interface. If your kernel supports alias interfaces, you can specify them with eth0:0 for the first alias of eth0. You can use them to assign a second address. To delete an alias interface use ifconfig eth0:0 down. Note: for every scope (i.e. same net with address/netmask combination) all aliases are deleted, if you delete the first (primary).upThis flag causes the interface to be activated. It is implicitly specified if an address is assigned to the interface.downThis flag causes the driver for this interface to be shut down.[-]arpEnable (or disable, if the "-" prefix is specified) the use of the ARPprotocol on this interface.[-]promiscEnable (or disable, if the "-" prefix is specified) the promiscuous mode of the interface. If promiscuous mode is enabled, all packets on the network will be received by the interface.[-]allmultiEnable or disable all-multicast mode. If multicast mode is enabled, all multicast packets on the network will be received by the interface.metric NThis parameter sets the interface metric, which is used by the interface to make routing decisions. N must be an integer between 0 and4294967295. If you're not sure what a network metric is, or whether you should change it, you can safely leave this setting alone.mtu NThis parameter sets the Maximum Transfer Unit (MTU) of an interface. This setting is used to limit the maximum packet size transferred by the interface. If you're not sure about it, you can safely leave this setting alone.dstaddr addressSet the remote IP address for a point-to-point link (such as PPP). This keyword is now obsolete; use the pointopoint keyword instead.netmask addressSet the IP network mask for this interface. This value defaults to the usual class A, B or C network mask (as derived from the interface IP address), but it can be set to any value.add address/prefixlenAdd an IPv6 address to an interface.del address/prefixlenRemove an IPv6 address from an interface.tunnel aa.bb.cc.ddCreate a new SIT (IPv6-in-IPv4) device, tunnelling to the given destination.irq addressSet the interrupt line used by this device. Not all devices can dynamically change their IRQ setting.io_addr addressSet the start address in I/O space for this device.mem_start addressSet the start address for shared memory used by this device. Only a few devices need this.media typeSet the physical port or medium type to be used by the device. Not all devices can change this setting, and those that can vary in what values they support. Typical values for type are 10base2 (thin Ethernet),10baseT (twisted-pair 10Mbps Ethernet), AUI (external transceiver) and so on. The special medium type of auto can be used to tell the driver to auto-sense the media. Again, not all drivers can do this.[-]broadcast [address]If the address argument is given, this will set the protocol broadcast address for this interface. Otherwise, it will set (or clear, if the "-" prefix is used) the IFF_BROADCAST flag for the interface.[-]pointopoint [address]This keyword enables the point-to-point mode of an interface, meaning that it is a direct link between two machines with nobody else listening on it. If the address argument is also given, set the protocol address of the other side of the link, just like the obsolete dstaddr keyword does. Otherwise, set or clear the IFF_POINTOPOINT flag for the interface.hw class addressSet the hardware address of this interface, if the device driver supports this operation. The keyword must be followed by the name of the hardware class and the printable ASCII equivalent of the hardware address. Hardware classes currently supported include ether (Ethernet),ax25 (AMPR AX.25), ARCnet and netrom (AMPR NET/ROM).multicastSet the multicast flag on the interface. This should not normally be needed as the drivers set the flag correctly themselves.addressThe IP address to be assigned to this interface.txqueuelen lengthSet the length of the transmit queue of the device. It is useful to set this to small values for slower devices with a high latency (such as a connection over a modem, or over ISDN) to prevent fast bulk transfers from disturbing interactive traffic like telnet too much.ifconfig examplesifconfigRunning ifconfig with no options will display the configuration of all active interfaces.ifconfig -aDisplays the configuration of all interfaces, both active and inactive.ifconfig eth0View the network settings on the interface eth0, which (under Linux) is the first Ethernet adapter installed in the system.ifconfig eth1 upActivate the network interface eth1.ifconfig wlan0 downDeactivate the network interface wlan0.ifconfig wlan1 122.140.201.66Configure the network interface wlan1 to use the static IP address 122.140.201.66.ifconfig wlan0 netmask 255.255.255.0Configure the network interface wlan0 to use the network mask 255.255.255.0.ifconfig eth0 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255Configure eth0 to use the static IP address 192.168.1.102 using the network mask255.255.255.0, and the broadcast address 192.168.1.255.Related commandsarp — Manipulate the system ARP cache.dhclient — Communicate with a DHCP server to obtain a dynamic IP address.ifdown — Disable a network interface.ifquery — Parse information about a network interface.ifup — Enable a network interface.ip — Display and manipulate information about routing, devices, policy routing and tunnels.iwconfig — Configure a wireless network interface.ping — Send ICMP ECHO_REQUEST packets to network hosts.netstat — Print information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.route — Display and manipulate the IP routing table. https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738926 2016-06-30 10:30:18 UTC https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738926 HACKS.EXE https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738930 Dont open the hacks.exe folder]]> 2016-06-30 10:30:23 UTC https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738930 vision hacks https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738967 2016-06-30 10:30:53 UTC https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738967 Get free wifi if you fake your MAC ADRESS  https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738975 HACKING]]> 2016-06-30 10:31:01 UTC https://padlet.com/alisonhannah/obueomqcyvo5/wish/115738975 Please donate csgo skins https://padlet.com/alisonhannah/obueomqcyvo5/wish/115739005
