Socat：允许重新连接到会话

我可以使用本地 PTY 链接设置 SSH 连接 - 我希望能够向远程端发送一些触发器，然后使用 screen 或 minicom 连接到会话，即：

socat PTY,link=/tmp/foo,raw,echo=0 EXEC:"ssh otherbox"

（或后台 socat）中

echo "securepassword|sudo -S bash"
screen /tmp/foo

然后在另一个窗口问题是 - 在回显之后，socat 断开 EXEC - 而不是保持它打开以便 PTY 连接继续。

有什么想法吗？（我可以用expect或empty-expect来做到这一点，但它对前者很感兴趣，而缓冲则在会话的交互部分中搞砸了后者。）

原文

I can setup an SSH connection with a local PTY link - and I want to be able to send some triggers to the remote end, then use screen or minicom to connect to the session ie:

socat PTY,link=/tmp/foo,raw,echo=0 EXEC:"ssh otherbox"

Then in another window (or background the socat)

echo "securepassword|sudo -S bash"
screen /tmp/foo

The trouble is - after the echo, socat disconnects the EXEC - rather than keeping it open so that the PTY connection carries on.

Any ideas? (I can sort of do this with expect or empty-expect, but its a faf with the former and buffering screws up the latter for the interactive part of the session.)
