ifconfig eth1 netmask 255.255.255.0 명령어가 안됩니다
몇시간 구글링 해도 해석하기 힘든 영어결과와 씨름하다가
이렇게 글을 올립니다. ㅠ.ㅠ
우분투 8.04버전을 사용중이고,
eth1은 무선랜(usb 무선랜 zio 1211)입니다. 이것을 ad-hoc 모드로 설정하고 (iwconfig 이용)
자우르스와 1:1 통신을 하려고 합니다.
아래 명령어를 실행하면 이렇게 에러가 뜹니다.
ifconfig eth1 add 192.168.3.1 netmask 255.255.255.0
SIOCSIFNETMASK: Cannot assign requested address
그래서 add [ip addr] 만 입력해보니 ip는 할당이 됩니다.
netmask 할당에서 왜 에러가 날까요?
그리고
iwconfig eth1 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device eth1 ; Invalid argument.
마스터 모드로는 왜 변경되지 않는건가요?
간단한 정보 올립니다.

NAME iwconfig - configure a wireless network interface SYNOPSIS iwconfig [interface] iwconfig interface [essid X] [nwid N] [mode M] [freq F] [channel C][sens S ][ap A ][nick NN ] [rate R] [rts RT] [frag FT] [txpower T] [enc E] [key K] [power P] [retry R] [modu M] [commit] iwconfig --help iwconfig --version ... PARAMETERS ... mode Set the operating mode of the device, which depends on the net- work topology. The mode can be Ad-Hoc (network composed of only one cell and without Access Point), Managed (node connects to a network composed of many Access Points, with roaming), Master (the node is the synchronisation master or acts as an Access Point), Repeater (the node forwards packets between other wire- less nodes), Secondary (the node acts as a backup mas- ter/repeater), Monitor (the node is not associated with any cell and passively monitor all packets on the frequency) or Auto. Example : iwconfig eth0 mode Managed iwconfig eth0 mode Ad-Hoc ... AUTHOR Jean Tourrilhes - <a href="mailto:jt@hpl.hp.com" rel="nofollow">jt@hpl.hp.com</a> ...master 모드를 지원하지 않는 놈인가보죠.
