开始使用:标准输入:通过ssh隧道使用scp时，设备的ioctl不适当 [英] Getting stty: standard input: Inappropriate ioctl for device when using scp through an ssh tunnel

问题描述

每个标题，当我尝试通过ssh隧道scp时，都会收到以下警告.就我而言，我不能直接scp到foo，因为设备foo上的端口1234被转发到专用网络上的另一台机器吧(而bar是向我提供通往192.168.1.23隧道的机器).

Per the title, I'm getting the following warning when I try to scp through an ssh tunnel. In my case, I cannot scp directly to foo because port 1234 on device foo is being forwarded to another machine bar on a private network (and bar is the machine that is giving me a tunnel to 192.168.1.23).

$ # -f and -N don't matter and are only to run this example in one terminal
$ ssh -f -N -p 1234 userA@foo -L3333:192.168.1.23:22
$ scp -P 3333 foo.py ubuntu@localhost:
ubuntu@localhost's password:
stty: standard input: Inappropriate ioctl for device
foo.py                                          100% 1829     1.8KB/s   00:00

有人知道为什么我可能会收到有关Inappropriate ioctl for device的警告吗?

Does anyone know why I might be getting this warning about Inappropriate ioctl for device?

推荐答案

当我在~/bashrc上包含以下行时，我遇到了完全相同的问题:

I got the exact same problem when I included the following line on my ~/bashrc:

stty -ixon

此行的目的是允许在反向搜索bash中使用 Ctrl-s .

The purpose of this line was to allow the use of Ctrl-s in reverse search of bash.

'stty'适用于用于交互式登录会话的ttys. .kshrc对所有会话都执行，包括那些没有stdin的会话 一个tty.除了将其移动到您的.profile之外，解决方案是 以交互外壳为条件，使执行成为条件.

'stty' applies to ttys, which you have for interactive login sessions. .kshrc is executed for all sessions, including ones where stdin isn't a tty. The solution, other than moving it to your .profile, is to make execution conditional on it being an interactive shell.

有几种方法可以检查互动壳.以下解决了bash的问题:

There are several ways to check for interecative shell. The following solves the problem for bash:

[[ $- == *i* ]] && stty -ixon
