<h3>远程诊断<a class="headerlink" href="#id5" title="永久链接至标题">¶</a></h3>

<p>服务器启动 Arthas Server 后，其他人可以使用 telnet 远程连接上去进程诊断，例如：</p>

<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">telnet 192.168.1.119 3658</pre></div>

<h3>sudo 支持<a class="headerlink" href="#sudo" title="永久链接至标题">¶</a></h3>
|
|
|
<p>成熟的线上管理环境一般都不会直接开放 JVM 部署用户权限给你，而是通过 sudo-list 来控制和监控用户的越权操作。由于 as.sh 脚本中会对当前用户的环境变量产生感知，所以需要加上 -H 参数</p>
