리눅스 NIC 관련 명령어 - ipconfig like commands

윈도우에서는 ipconfig 라는 녀석으로 유선랜의 경우에는 dhcp까지 설정이 가능하다.
ipconfig /all <- 모든 어댑터 리스트 보기
ipconfig /renew <- dhcp 갱신

C:\>ipconfig /? USAGE:     ipconfig [/? | /all | /renew [adapter] | /release [adapter] |               /flushdns | /displaydns | /registerdns |               /showclassid adapter |               /setclassid adapter [classid] ] where     adapter         Connection name                    (wildcard characters * and ? allowed, see examples)     Options:        /?           Display this help message        /all         Display full configuration information.        /release     Release the IP address for the specified adapter.        /renew       Renew the IP address for the specified adapter.        /flushdns    Purges the DNS Resolver cache.        /registerdns Refreshes all DHCP leases and re-registers DNS names        /displaydns  Display the contents of the DNS Resolver Cache.        /showclassid Displays all the dhcp class IDs allowed for adapter.        /setclassid  Modifies the dhcp class id. The default is to display only the IP address, subnet mask and default gateway for each adapter bound to TCP/IP. For Release and Renew, if no adapter name is specified, then the IP address leases for all adapters bound to TCP/IP will be released or renewed. For Setclassid, if no ClassId is specified, then the ClassId is removed. Examples:     > ipconfig                   ... Show information.     > ipconfig /all              ... Show detailed information     > ipconfig /renew            ... renew all adapters     > ipconfig /renew EL*        ... renew any connection that has its                                      name starting with EL     > ipconfig /release *Con*    ... release all matching connections,                                      eg. "Local Area Connection 1" or                                          "Local Area Connection 2"

리눅스에서는 조금은 분화가 되어있다.(윈도우에 익숙해서인지 불편하다)
ifconfig - configure a network interface
dhclient - Dynamic Host Configuration Protocol Client

iwconfig - configure a wireless network interface
iwspy - Get wireless statistics from specific nodes
iwlist - Get more detailed wireless information from a wireless interface

굳이 윈도우와 비교를 하자면

windows	linux
ipconfig	ifconig, iwconfig
ipconfig /renew	dhclient, dhcpcd
