telnet拉數據超時問題

Question

這是我通過普通telnet或甚至通過ruby telnet獲得的數據。我不知道如何告訴它退出當它到達END DATABASE

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

END DATABASE 

這裏是我的代碼：

#!/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 

當這個運行時，它輸出的所有數據，然後等待和錯誤：

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

我真的不知道該從哪裏出發，我已經看過this頁面瞭解如何處理它的更多信息，但我找不到任何東西。

感謝您的任何幫助。

看來你在這裏使用的是非標準的telnet服務器。初始化時請將「Telnetmode」設置爲false。

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