 **Step 6: Test it!**

 From another system on the same virtual network `curl http://IP.ADD.RE.SS/`

 ## Dynamic Linking 
 
+Build the library:
+
 `make linux_shared_lib`
-s
+
 This will build a binary called `zerotier-sdk-service` and a library called `libztintercept.so`. It will also build the IP stack as `build/liblwip.so`. 
 
 The `zerotier-sdk-service` binary is almost the same as a regular ZeroTier One build except instead of creating virtual network ports using Linux's `/dev/net/tun` interface, it creates instances of a user-space TCP/IP stack for each virtual network and provides RPC access to this stack via a Unix domain socket. The latter is a library that can be loaded with the Linux `LD_PRELOAD` environment variable or by placement into `/etc/ld.so.preload` on a Linux system or container. Additional magic involving nameless Unix domain socket pairs and interprocess socket handoff is used to emulate TCP sockets with extremely low overhead and in a way that's compatible with select, poll, epoll, and other I/O event mechanisms.
