你可以使用strace命令来跟踪ssh登录过程中的系统调用,从而获取登录凭证。下面是一个示例命令:
```
strace -e trace=read,write ssh <username>@<hostname>
```
这个命令会跟踪ssh进程的读写系统调用,包括用户名和密码的传输过程。请注意,这种方式只适用于你有合法权限访问该系统的情况下进行调试和分析。
然而,请注意使用strace可能涉及到违反隐私和安全规定的风险。在实际情况下,建议遵循合法和道德的原则,并且仅在合法授权的范围内使用该工具。

```
$ strace -f firefox
```
4. 只跟踪特定系统调用:
```
$ strace -e open command
```
例如:

linux strace
strace is a command-line tool in Linux used to trace and debug system calls made by a program. It allows you to monitor the interactions between processes and the Linux kernel. By tracing system calls, you can gain insights into the behavior of a program, identify errors, and understand its resource usage.
To use strace, you simply need to run it followed by the command or program you want to trace. For example:
```
strace ls -l
```
This command will trace the system calls made by the 'ls -l' command.
Strace provides detailed information about each system call, such as the arguments passed, return values, and any errors encountered. It can be useful for troubleshooting issues related to file access, networking, process management, and more.
Keep in mind that strace produces a lot of output, so it is often helpful to redirect the output to a file for further analysis. You can do this by using the '>' symbol followed by the filename:
```
strace ls -l > output.txt
```
I hope this helps! Let me know if you have any more questions.
