问题描述
我有一台接受telnet连接进行管理的服务器.我错过了命令历史记录，因此我想让telnet会话支持它.我的问题:
I have a server that accept telnet connections for management. I miss the command history so I want to make my telnet session support it. My questions:
1)我必须在服务器端实现该功能，以便服务器将过去的命令发送给客户端，然后客户端可以重新执行吗?
1) Do I have to implement that on the server side, so the server will send the past commands to the client and then the client can re-execute?
2)是否总能在telnet客户端中实现此功能(不与服务器打乱)?
2) Is there anyway to implement this functionality in the telnet client (not messing with the server) ?
如果答案为1)，那么我需要知道如何在telnet会话中捕获并发送上下箭头键，而不必按Enter键.
If answer is 1) then I need to know how to capture and send the up and down arrow keys on my telnet session without having to press enter.
推荐答案
这不是服务器问题.只需在您的telnet客户端上使用 rlwrap .它使您无需编程即可使用readline.
This isn't a server issue. Just use rlwrap with your telnet client. It gives you readline with no programming.
$ rlwrap telnet server port
(我实际上使用nc代替telnet，因为它更易于使用并且更强大.)
(I actually use nc instead of telnet since it is easier to use and is more robust.)
