常常用来建立ssh连接发送一条命令,但有时需要模拟ssh客户端功能,即直接连接上远程主机一直操作:(http://www.zhihu.com/question/30368538/answer/47835043)
package main import ( "golang.org/x/crypto/ssh" "log" "os" ) func main() { ce := func(err error, msg string) { if err != nil { log.Fatalf("%s error: %v", msg, err) } } client, err := ssh.Dial("tcp", "172.16.116.200:22", &ssh.ClientConfig{ User: "root", Auth: []ssh.AuthMethod{ssh.Password("^Two^Ten=1024$")}, }) ce(err, "dial") session, err := client.NewSession() ce(err, "new session") defer session.Close() session.Stdout = os.Stdout session.Stderr = os.Stderr session.Stdin = os.Stdin modes := ssh.TerminalModes{ ssh.ECHO: 0, ssh.TTY_OP_ISPEED: 14400, ssh.TTY_OP_OSPEED: 14400, } err = session.RequestPty("xterm", 25, 80, modes) ce(err, "request pty") err = session.Shell() ce(err, "start shell") err = session.Wait() ce(err, "return") }
实际使用中有缺陷,通过 tab 补全时并不能正确显示。还是直接使用shell编写吧,简单实用:
#!/usr/bin/expect set timeout 30 spawn ssh root@122.116.16.200 expect "password:" send "123456\r" interact
