下面是一个HTML网页示例，可以让您使用telnet或ssh登录到远程计算机并使用操作命令：
<!DOCTYPE html>
<html>
<head>
<title>Telnet and SSH Login Operation Command Window</title>
</head>
<body>
<h1>Telnet and SSH Login Operation Command Window</h1>
<p>This is a webpage that allows you to login to a remote computer using telnet or ssh.</p>
<form action="/" method="post">
<input type="text" name="hostname" placeholder="Hostname">
<input type="text" name="username" placeholder="Username">
<input type="password" name="password" placeholder="Password">
<input type="radio" name="protocol" value="telnet" checked="checked"> Telnet
<input type="radio" name="protocol" value="ssh"> SSH
<input type="submit" value="Login">
</form>
<?php
if (isset($_POST['hostname']) && isset($_POST['username']) && isset($_POST['password'])) {
$hostname = $_POST['hostname'];
$username = $_POST['username'];
$password = $_POST['password'];
$protocol = $_POST['protocol'];
if ($protocol == "telnet") {
$command = "telnet $hostname";
} else if ($protocol == "ssh") {
$command = "ssh $username@$hostname";
}
exec($command, $output);
if ($output === 0) {
echo "Login successful.";
echo "<br>";
echo "Enter operating commands:";
while (true) {
$command = trim(fgets(STDIN));
if ($command == "exit") {
break;
}
$output = shell_exec($command);
echo $output;
}
} else {
echo "Login failed.";
}
}
?>
</body>
</html>此代码将创建一个网页，允许您输入远程计算机的主机名、用户名和密码。然后您可以选择使用 telnet 或 ssh 登录到远程计算机。如果登录成功，网页会提示“登录成功”。然后它会提示您输入操作命令。您可以输入通常在远程计算机上输入的任何操作命令。输入完命令后，可以键入“exit”退出命令提示符。
