最好的办法就是把树莓派设成静态IP 网上已经有教程

目前我的pi默认还是dhcp自动分配的

linux下查找pi

第一步察看局域网内在线主机ip地址

推荐用arp-scan扫描局域网IP地址找到raspberry以及ip（autoscan工具也可以？）

或者

nmap -sP 192.168.1.100-110


Starting Nmap 5.21 ( http://nmap.org ) at 2013-10-19 21:39 CST
Nmap scan report for 192.168.1.100
Host is up (0.18s latency).
Nmap scan report for 192.168.1.102
Host is up (0.17s latency).
Nmap scan report for 192.168.1.103
Host is up (0.00021s latency).
Nmap scan report for 192.168.1.104
Host is up (0.066s latency).
Nmap scan report for 192.168.1.105
Host is up (0.25s latency).
Nmap scan report for 192.168.1.107
Host is up (0.20s latency).
Nmap scan report for 192.168.1.108
Host is up (0.0096s latency).

另外一个察看某ip主机名

nmblookup -A ip  察看主机名

第二步

使用putty或者vnc连接树莓派

connect

最后推荐一个linux软件下载站
