Alauddin Maulana Hirzan 💻<p>I wrote shell and python scripts as a wrapper for ngctl dot (netgraph Graphviz export) and dot (Graphviz dot to png). Available through my repository : </p><p>a.

Run these script with extra precaution. I am not responsible for any broken system or data lost.

Alauddin Maulana Hirzan 💻<p>I need help troubleshooting my network simulation. This simulation simulates simple network with a router and a client (both are jails). The router provides internet to client 1 through netgraph.</p><p>Setup: <br>1. Host-Router (Epair)<br>2. Router-Bridge-Client1 (NetGraph)</p><p>What were working:<br>1. Router can ping 1.1.1.1 (Internet Access)<br>2. Router can ping host gateway (192.168.200.1)<br>3. Router can ping client 1 (192.168.150.10)<br>4. Client 1 can ping the router (192.168.150.1)</p><p>What were not working:<br>1. Client 1 cannot ping 192.168.200.1<br>2. Client 1 cannot ping 1.1.1.1</p><p>What I have done:<br>1. Enabled gateway_enable in rc.conf<br>2. Configured all forwarding in sysctl<br>3. Create default route to 192.168.200.1</p><p><a href="https://mastodon.bsd.cafe/tags/freebsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>freebsd</span></a> <a href="https://mastodon.bsd.cafe/tags/netgraph" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>netgraph</span></a> <a href="https://mastodon.bsd.cafe/tags/troubleshooting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>troubleshooting</span></a></p>
Alauddin Maulana Hirzan 💻<p>Productive procrastination with Netgraph. I have successfully deployed a simple peer-to-peer connection with traffic mirroring capability that is suitable for Wireshark sniffing. What makes Netgraph great is that no additional software is required at all. I will note these personal discoveries into my notes (and eventually, turn it into an ebook?)</p><p><a href="https://mastodon.bsd.cafe/tags/freebsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>freebsd</span></a> <a href="https://mastodon.bsd.cafe/tags/netgraph" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>netgraph</span></a></p>
Alauddin Maulana Hirzan 💻<p>Studying at the morning is the best way to learn. I have successfully deployed Client1-Router-Client2 with netgraph and vnet. Screenshot 1 is the deployment result, and Screenshot 2 dot image produced by netgraph with some editing (my first time hacking Graphviz dot file, and so confusing. But actually quite simple).</p><p>My last objectives are to route the traffic between client 1 and client 2, and automate the netgraph process</p><p><a href="https://mastodon.bsd.cafe/tags/freebsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>freebsd</span></a> <a href="https://mastodon.bsd.cafe/tags/netgraph" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>netgraph</span></a></p>
