如何记录ssh调试信息？ [英] How to log ssh debug info?

问题描述

我需要将ssh debug信息的输出写入文件。这个

I need to write the output of ssh debug info into the file. This

ssh -v [e-mail] > result.txt
ssh -v [e-mail] 2>&1 > result.txt

不起作用，文件result.txt为空，但在屏幕上看到一堆调试行，如：

doesn't work, the file result.txt is empty, but on the screen i see bunch of debug lines, like:

OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to 172.16.248.xx [172.16.248.xx] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
etc

有没有办法将这些行重定向到文件？

Is there a way to redirect these lines to the file?

推荐答案

您必须在命令行中更改重定向的顺序：

You have to change the order of the redirections on the command line:

ssh -v [e-mail] >result.txt 2>&1

或只是：

ssh -v [e-mail] 2>result.txt
