Question

我想编写一个脚本，根据Net :: Telnet在ruby中建立的连接中的横幅输出，使用用户名和密码进行登录：

登录并执行一些命令的代码（命令在文件＆＃34;命令＆＃34;）中：

USER = "myuser"
PASS = "mypass"
USER2 = "my2ndUser"
PASS2 = "my2ndPass"

ENABLEPASS = "myenablepass"
ENABLEPASS2 = "my2ndEnablePass"

tn = Net::Telnet::new("Host" => line,
"Timeout" => 10,
"Waittime" => 0.1,
"Prompt" => /[#>:]/n) { |resp| print "==> "+resp}

tn.cmd(USER) { |c| print c }
tn.cmd(PASS) { |c| print c }
tn.cmd("terminal length 0") { |c| print c }
tn.cmd("en") { |c| print c }
tn.cmd(ENABLEPASS) { |c| print c }
tn.cmd("\n")  { |c| print c }

File.open('commands').each do |l|
tn.cmd(l) { |c| print c }
end
tn.cmd("\n")  { |c| print c }
tn.cmd("\n")  { |c| print c }


tn.close

所需：相同的脚本，但在说出＆＃34; my2ndrouter＆＃34;时使用第二个参数。在登录尝试完成时输出的路由器的banner / MOTD中（就在您必须插入用户和传递之前）

如果我的方案正确，您可以使用waitfor来虹吸数据，直到您收到提示接收用户名。然后处理waitfor块中的数据以检测要使用的两组参数中的哪一组。

routers = [
  { "user" => "myuser", "pass" => "mypass", "enablepass" => "myendablepass" },
  { "user" => "my2ndUser", "pass" => "my2ndPass", "enablepass" => "my2ndEndablePass" }
]

tn = Net::Telnet::new("Host" => line,
"Timeout" => 10,
"Waittime" => 0.1,
"Prompt" => /[#>:]/n) { |resp| print "==> "+resp}

my_router = routers[0]
# Replace /login:/ with whatever regexp that matches your login prompt, e.g. your catch-all /[#>:]/n
tn.waitfor(/login:/) { |banner| my_router = routers[1] if banner.match("my2ndrouter") }

tn.cmd(my_router['user']) { |c| print c }
tn.cmd(my_router['pass']) { |c| print c }
tn.cmd("terminal length 0") { |c| print c }
tn.cmd("en") { |c| print c }
tn.cmd(my_router['enablepass']) { |c| print c }
tn.cmd("\n")  { |c| print c }

File.open('commands').each do |l|
tn.cmd(l) { |c| print c }
end
tn.cmd("\n")  { |c| print c }
tn.cmd("\n")  { |c| print c }


tn.close

使用用户并在ruby的telnet类中基于横幅传递
