windows上有putty可以通过ssh协议连接远程linux系统。
mac上也可以用终端连接，转自：http://www.unixnewbie.org/putty-equivalent-for-mac-os-x/
In Mac, there is a similar, built-in application called Terminal.
To start Terminal, go to your Mac’s Applications folder => click on the Utilities folder => then click on Terminal.
How to access a web server using the Terminal?
# ssh username@server.address.com example: # ssh root@unixnewbie.org - when prompted for the password, enter your web server password. - to quit the session, type "exit".
当然mac上也可以像windows上的winscp一样进行文件操作。参考：http://www.openssh.com/macos.html
我用的工具是Cyberduck http://cyberduck.ch/
如上图，选择Open Connection
在协议那一栏选则SFTP(SSH File Transfer Protocol)
然后输入用户名，密码和地址即可~
