Question

这是我通过普通telnet或甚至通过ruby telnet获得的数据。我不知道如何告诉它在END DATABASE

时退出

# Manual telnet method
Trying 10.1.1.12...
Connected to 10.1.1.12.
Escape character is '^]'.
F#1=
F#1=
BEGIN DATABASE

END DATABASE

这是我的代码：

#!/usr/local/bin/ruby
require 'net/telnet'
localhost = Net::Telnet::new("Host" => "10.1.1.12", "Timeout" => 10, "Port" => 10001) { |resp| print "===> " + resp }
localhost.cmd("F#1=") do |data| 
   print data
end

当它运行时，它输出所有数据然后等待和错误：

/usr/lib/ruby/1.8/net/telnet.rb:557:in `waitfor': timed out while waiting for more data (Timeout::Error)

老实说我甚至不确定从哪里开始，我已经查看this页面了解更多关于如何处理它的信息，但我找不到任何东西。

感谢您的帮助。

您似乎在这里使用非标准的telnet服务器。初始化时请将“Telnetmode”设置为false。

localhost = Net::Telnet::new("Host" => "10.1.1.12", "Telnetmode" => false, "Timeout" => 10, "Port" => 10001) { |resp| print "===> " + resp }

telnet拉数据超时问题
