openvpn使用详解
前言
测试单个提示类
如果说上天赋予了我精通某项技术的能力
多个类
- 很多软路由集成的都是社区版，比如openwrt和爱快
- 同样，很多软路由也集成了客户端
- 我们不能把openvpn的服务端和客户端搞混淆
测试代码块，末尾加四个英文空格
console.log("Hello, world!");

测代码块生成
测试JavaScript代码
document.addEventListener('DOMContentLoaded', function() {
const preElements = document.querySelectorAll('pre');
preElements.forEach(preElement => {
const divWrapper = document.createElement('div');
divWrapper.classList.add('pre-wrapper', 'pt-4', 'rounded');
preElement.parentNode.insertBefore(divWrapper, preElement);
divWrapper.appendChild(preElement);
});
}); {
hljs.addPlugin({
'after:highlightBlock': ({ block }) => {
const blockParent = block.closest('pre');
if (!blockParent) return;
// 添加Bootstrap样式类到blockParent
blockParent.classList.add('pre-wrapper', 'fs-6', 'd-flex');
// 创建行号
const lines = document.createElement('code');
const lineNumbers = [...Array(block.textContent.trimEnd().split(/\n/).length)].map((_, i) => i + 1).join('\n');
// 为行号添加Bootstrap样式类
lines.classList.add('hljs', 'border-end', 'border-light', 'opacity-25', 'flex-shrink-0', 'text-end');
lines.style.userSelect = 'none'; // Disable selection
// 设置行号内容
lines.textContent = lineNumbers;
// 将行号元素插入到block之前
blockParent.insertBefore(lines, block);
// 设置block样式
block.classList.add('flex-grow-1');
}
});

openvpnas可能碰到的问题及解决方案
-
登录web页面，忘记管理员密码怎么办？
系统初始管理员用户名：openvpn
cd /usr/local/openvpn_as/scripts
./sacli --user "openvpn" --key "prop_superuser" --value "true" UserPropPut
./sacli --user "openvpn" --key "user_auth_type" --value "local" UserPropPut
./sacli --user "openvpn" --new_pass=<PASSWORD> SetLocalPassword
./sacli start
-
ping延迟一下高一下低怎么排查和解决？
MTU大小：UDP数据包的最大传输单元（MTU）大小可能导致延迟增加。如果MTU设置不当，数据包可能需要进行分片或重新组装，导致额外的延迟。您可以尝试调整UDP连接的MTU大小，确保其适合您的网络环境。
- 在哪里调整？调整多少？
登录web控制台，点击左侧CONFIGURATION,Advanced VPN,滑到页面底部，在Server Config Directives和Client Config Directives分别填入MTU值，填写格式为：
tun-mtu 数值，比如tun-mtu 1280
-
./sacli --user "openvpn" --key "prop_superuser" --value "true" UserPropPut ./sacli --user "openvpn" --key "prop_superuser" --value "true" ./sacli --user "openvpn" --key "prop_superuser" --value ./sacli --user "openvpn" --key "prop_superuser"
