<p>I went through gobyexample and would like put the knowledge to good use. However, I don't even know where to start /=. Anyways, i'm going to further breaker down the project into smaller pieces and hope this sub can give me pointers along the way.</p>
<p>There will be two part of the software. The agent and the server. For now I just want to have a simple connection between them through a specific port. I want it to be fast and secure(hence my choice of golang).</p>
<p>So where do I even start? For security do use the .key and .pub method? or there are some well known library in golang that's specifically design for this? </p>
<p>Any guide out there on how to write a server/agent in golang? I'm really beginner in this. I'm a system admin but I have no knowledge in writing system software at all.</p>
<hr/>**评论：**<br/><br/>yuhatemews: <pre><p>Hate to be that guy, and maybe I'm just old and this is what passes for a systems administrator these days. How do you have no knowledge writing system software being a sys admin? </p>
<p>Well that rant out of the way I'm glad you are getting your feet wet and looking to expand your skill set that will without a doubt make your life better and increase the value and opportunities within your organization.</p>
<p>I would suggest reading thru the excellent go primers on the net. Here is some explicit suggestions.</p>

<p>Good gophering and have fun!</p></pre>juniorsysadmin1: <pre><p>I mean, I read,package, edit one here and there but never wrote one from ground up.</p></pre>celebratednut: <pre><p>There are Two basic client-server connection options, the first being http connections (website) the other being sockets.
You mention specific port so Im guessing you want socket connections.</p>
<p>You also mention security, on sockets the key/pub method is called TLS. This is NOT the place to start, it is the place to END the basic concept before you start adding features. </p>
<p>To start look at <a href="https://golang.org/pkg/" rel="nofollow">golang packages</a>. I suggest only starting out with Go vanilla packages to get used to the way Go does things. </p>
<p>I also think that starting with domain sockets may be a little too big of a challenge to start with, first try building a couple input/output functions. then when youre ready you can redirect them into sockets.</p>
<p>If you're dead set on starting with sockets then look at <a href="https://golang.org/pkg/net/" rel="nofollow">golang net package</a></p></pre>hnyakwai: <pre><p>So, if yoy really want simple, just read the godoc for the net package. Specifically the net.Listener example shows a basic socket server. </p>
<p>However, this will not be secure. Then you need to wrap the connection with TLS, and figure out how certificates should work.</p>
<p>Then you are going to have to figure out what you want your protocol to look like, how you are going to serialize data, how to handle broken connections, etc.</p>
<p>If you actually want to get something done that will work and be secure, save yourself the trouble and use GRPC. If you just want to learn, start with reading the "net" godoc and work your way down the rabbit hole from there.</p></pre>anoland: <pre><p>There is a lot of good info in this talk.</p>
