由于每次登录都要输入用户名和密码，还有个别设备不能用SSH2，而我又不记得是哪几台？？！！

写个脚本，做个按钮，在Button Bar，New Button，在Action -> Function选Run Script，在Run Script选好脚本路径，自己命名个Label。

给2个版本的示例代码，都是可以直接运行的，一个简单点，但扩展性不好；一个复杂点，但具有很强的扩展性。

版本1：

单个文件，用户名和密码保存在全局变量中。

# $language = "python"

# $interface = "1.0"

#--------------------------------------------------------------------------------------

import os

#--------------------------------------------------------------------------------------

szSSH2UserName = '"asdaf adsf"'

szSSH2Passwd = "adsfqweradsf"

szTelnetUserName = "asdaf adsf"

szTelnetPasswd = szSSH2Passwd

def connectFun():

szHost = crt.Dialog.Prompt("Enter host IP address : ", "Host IP", "", False)

ssh2cmd = "/SSH2 /L %s /PASSWORD %s %s" % (szSSH2UserName, szSSH2Passwd, szHost)

telnetcmd = "/Telnet %s" % (szHost)

oTab = 0

crt.Screen.Synchronous = True

try:

crt.Session.ConnectInTab(ssh2cmd)

oTab = crt.GetActiveTab()

except:

try:

crt.Session.ConnectInTab(telnetcmd)

oTab = crt.GetActiveTab()

oTab.Screen.WaitForString("name")

oTab.Screen.Send(szTelnetUserName + "\r")

oTab.Screen.WaitForString("assword")

oTab.Screen.Send(szTelnetPasswd + "\r")

except:

crt.Dialog.MessageBox(szHost + " Login Failed!","Failed")

return oTab

connectFun()

版本2：

分三个文件，分别是autoConnect.py、connectEnv.py和UserNameAndPassword.txt。(放在同一目录下，且只要在crt中运行autoConnect.py就行了)

autoConnect.py登录逻辑代码，包括用户名和密码读取。

connectEnv.py打包了crt所有的API。可参考我重新打包的crt环境类

UserNameAndPassword.txt保存用户名和密码，第一行是用户名，第二行是密码。

autoConnect.py

# $language = "python"

# $interface = "1.0"

#--------------------------------------------------------------------------------------

def getScriptPath():

return os.path.split(os.path.realpath(__file__))[0]

sys.path.append(getScriptPath())
