接收方无法获取IP
问题
接收方一直在提示在获取ip中
然后我输入ifconfig也没有看到bridge100的信息(一般bridge100是Mac共享wifi的网卡)
估计是这玩意没启动起来
因为之前由于工作的原因需要修改网段(bridge100默认在192.168.2.1里),有些同学如果公司网段和这个冲突,那也得改bridge100的网段,一般是这样修改
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkNumberStart 192.168.0.0
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkNumberEnd 192.168.0.20
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkMask 255.255.255.0
这个很简单,就是设置bridge100的起始ip和结束ip,还有子网掩码
具体的信息都会在/Library/Preferences/SystemConfiguration/com.apple.nat.plist里
然后我悲剧的发现我起始地址和结束地址设成了....
42 <key>SharingNetworkMask</key>
43 <string>255.255.255.0</string>
44 <key>SharingNetworkNumberEnd</key>
45 <string>192.168.2.254</string>
46 <key>SharingNetworkNumberStart</key>
47 <string>192.168.105.254</string>
估计是我之前手抖动...设置错了..
原因比较奇怪,这个文件好像不能手动改,
必须上文的命令行
现在设置成了
42 <key>SharingNetworkMask</key>
43 <string>255.255.255.0</string>
44 <key>SharingNetworkNumberEnd</key>
45 <string>192.168.2.20</string>
46 <key>SharingNetworkNumberStart</key>
47 <string>192.168.2.1</string>
bridge100也出来了
