更改MAC地址后无法连接互联网

更改MAC地址后无法连接互联网

我一直在制作一个 BASh 脚本,将您的 MAC 地址更改为您从列表中选择的任何制造商的地址。在脚本运行的最后一部分,它会在完成之前停止。这是该部分的代码:

function spoofUseMAC() {

  echo
  read -p "[*] $($stopAllFX; $bgBlack; $white)Enter the number code for manufacturer: >>> " num
  echo "[-] Generating MAC Address"
  num=$( expr $num - 1 )
  declare -a array
  while read -r; do
    array+=( "$REPLY" )
  done < addr.txt
  end=$( for i in {1..6} ; do echo -n ${hexchars:$(( $RANDOM % 16 )):1} ; done | sed -e 's/\(..\)/:\1/g' )
  macAddress=${array[$num]}$end
  echo "[-] MAC Address generated !"
  echo "[-] Using address: $macAddress"

  $skyBlue; $bold; echo
  ifconfig
  $white
  read -p "[*] $($stopAllFX; $bgBlack; $white)Select an interface: >>> " iface
  $yellow; echo "[-] $iface selected !"
  $white; echo  "[-] Disabling $iface ..."
  ifconfig $iface down
  ifconfig '$iface' hw ether '$macAddress'
  echo "[-] MAC Address spoofed !"
  sleep 1
  echo "[-] Enabling $iface ..."
  ifconfig '$iface' up
  echo "[-] $iface enabled !"
  echo "[-] Using address: $macAddress"
  exit

}

function spoofSearchAgainOrNot() {

  $bold; $white; echo
  echo "[*] $($stopAllFX; $bgBlack; $white)Please select an option from the list below:"
  $yellow; $bold; echo "        [$($white)0$($yellow)] $($stopAllFX; $bgBlack; $white)Search again"
  $yellow; $bold; echo "        [$($white)1$($yellow)] $($stopAllFX; $bgBlack; $white)Use one of these"
  read -p ">>> " searchAgainOrNot
  if [[ "$searchAgainOrNot" == "0" ]]; then
    spoofSearch
  elif [[ "$searchAgainOrNot" == "1" ]]; then
    spoofUseMAC
  else
    spoofSearchAgainOrNot
  fi

}

# Spoof, search option selected
function spoofSearch() {

  $bold; echo
  read -p "[*] $($stopAllFX; $bgBlack; $white)Search for a manufacturer: >>> " search
  $blue; awk -F '#' '{printf("%10d %s\n", NR, ":" $1 )}' /usr/bin/oui.txt | grep -i $search

  spoofSearchAgainOrNot

}

# Spoof
function spoof() {

  echo; $white
  echo "[*] $($stopAllFX; $bgBlack; $white)Please select an option from the list below:"
  $yellow; $bold; echo "        [$($white)0$($yellow)] $($stopAllFX; $bgBlack; $white)Search for a manufacturer"
  $yellow; $bold; echo "        [$($white)1$($yellow)] $($stopAllFX; $bgBlack; $white)Browse for a manufacturer through $($bold)long $($stopAllFX; $bgBlack; $white)list"
  read -p ">>> " searchOrBrowse
  if [[ $searchOrBrowse == "0" ]]; then
    spoofSearch
  elif [[ $searchOrBrowse == "1" ]]; then
    spoofBrowse
  else
    spoof
  fi

}

为什么运行此脚本后我无法使用互联网(git clone说)?could not resolve hostname: github.com为什么还没有完成?

编辑:这应该适用于 MacOS 和 Linux。在 MacOS 上,没有ip route命令,但在 Linux 上,ip route结果是:

192.168.0.0/24 dev wlp1s0  proto kernel scope link  src 192.168.0.18 
192.168.0.0/24 dev wlp1s0  proto kernel scope link  src 192.168.0.18  metric 600

有些卡对于更改/欺骗 MAC 地址有点挑剔。

在 OSX 中,接口 MAC 地址更改,特别是 wifi 接口,必须执行多次才能正确,例如经常循环,因为我怀疑它必须在特定时间内完成;对于最新版本的 OSX/MacOS,第一次时通常不会假设这一点。

值得注意的是,在 OSX 中,接口/驱动程序在 MAC 之后似乎会混淆几秒钟,但它们确实会恢复。

稀有品牌不会喜欢它,在某些品牌中,不建议您更改前 3 个八位字节(前 6 位数字,减去“:”),即制造商 ID。

您经常会丢失默认路由,或者路由器/AP 可能会丢失您是谁的概念;虽然该过程大部分应该是自动的,但在某些情况下,在 Linux 中,您可能必须在更改 MAC 地址后重新启动 DHCP 服务。

我发现了问题:其中一个$ifaces 周围有引号,而它不应该有。
