从字符串中获取命令(密码)并将其设置为InputStream到Java(JSCH)中的Unix服务器 [英] Take commands(password) from string and set as InputStream to Unix servers in Java (JSCH)
问题描述
几乎与此主题类似,但此处我不是超级用户--stdin。
Almost similar to this topic, but here I am not a superuser to use --stdin.
所以我找到了另一种方法,我会在后台打开一个shell并通过字符串给shell输入
通过 InputStream
So I found an other way round, I would open a "shell" in background and give input to shell via a String
through InputStream
我做了如下代码:
String s = "cd bin\n";
byte bb[] = s.getBytes();
InputStream intt = new ByteArrayInputStream(bb);
channel.setInputStream(new FilterInputStream(intt) {
public int read(byte[] b, int off, int len) throws IOException {
return in.read(b, off, (len > 1024 ? 1024 : len));
}
});
现在,当我只想执行一个命令但是我想给出多个命令时,这种方法非常有效我面临的问题。
Now this works perfectly when I want to execute only one command but I want to give multiple commands, for which I am facing issue.
有什么建议吗?
问候,

推荐答案
我找到了一个问题的解决方案我问过,不知道它是否有完整的证明解决方案,因为我在有限的时间内进行了测试,并且我做了它的野兽。
I found a solution to question I asked, don't know if its a full proof solution since I tested with limited period of time and I did it beast way I can.
channel = session.openChannel("exec");
((ChannelExec) channel).setCommand(command);
((ChannelExec) channel).setPty(true);
在命令字符串中
String command = "(echo old_password; echo new_password; echo new_password) | passwd username";
或者如果不是超级用户,
or if not a superuser then,
String command = "(echo old_password; echo new_password; echo new_password) | passwd"
就是这样;)
