SecureCRT 在 Debian 上的自定义脚本支持与实现

脚本支持概览

内置脚本快速上手 Python 示例

# $language = "python"
# $interface = "1.0"

import time

user = 'admin'
passwd = 'YourPassword'  # 建议改为密钥或更安全的方式

def log_name():
    return time.strftime('%Y-%m-%d-%H-%M-%S', time.localtime())

def main():
    crt.Screen.Synchronous = True
    with open('ip.txt') as f:
        hosts = [line.strip().split()[0] for line in f if line.strip()]

    for ip in hosts:
        # 可根据实际设备调整参数,示例为通用 SSH 连接
        cmd = f"/SSH2 /L {user} /PASSWORD {passwd} /C 3DES /M MD5 {ip}"
        crt.Session.ConnectInTab(cmd)
        time.sleep(1)
        crt.Screen.Send('\r')
        crt.Screen.WaitForString('>')

        ts = log_name()
        crt.Session.LogFileName = f"{ts}_{ip}.log"
        crt.Session.Log(True)

        crt.Screen.Send('uname -a\r')
        crt.Screen.WaitForString('>')
        crt.Screen.Send('uptime\r')
        crt.Screen.WaitForString('>')

        # 断开当前标签页
        crt.Session.Disconnect()

会话登录动作与简单自动化

命令行与 Expect 的外部自动化

#!/usr/bin/expect -f
set timeout 20
set session [lindex $argv 0]
set username [lindex $argv 1]
set password [lindex $argv 2]
set command [lindex $argv 3]

spawn securecrt -ssh $username@$session -password $password
send "$command\r"
expect eof
