Rizin can be run locally, or it can be started as a server process which is controlled by a local rizin process. This is possible because everything uses rizin's IO subsystem which abstracts access to system(), cmd() and all basic IO operations so to work over a network.
Help for commands useful for remote access to rizin:

You can learn rizin remote capabilities by displaying the list of supported IO plugins:
A little example should make this clearer. A typical remote session might look like this:
At the remote host1:
$ rizin rap://:1234
At the remote host2:
$ rizin rap://:1234
$ rizin -
[0x004048c5]> =+ rap://<host1>:1234//bin/ls Connected to: <host1> at port 1234 waiting... ok [0x004048c5]> = 0 - rap://<host1>:1234//bin/ls
You can open remote files in debug mode (or using any IO plugin) specifying URI when adding hosts:
[0x004048c5]> =+ =+ rap://<host2>:1234/dbg:///bin/ls Connected to: <host2> at port 1234 waiting... ok 0 - rap://<host1>:1234//bin/ls 1 - rap://<host2>:1234/dbg:///bin/ls
To execute commands on host1:
[0x004048c5]> =0 px [0x004048c5]> = s 0x666
To open a session with host2:
[0x004048c5]> ==1 fd:6> pi 1 ... fd:6> q
To remove hosts (and close connections):
You can also redirect rizin output to a TCP or UDP server (such as
nc -l). First, Add the server with '=+ tcp://' or '=+ udp://', then you can redirect the output of a command to be sent to the server:
[0x004048c5]> =+ tcp://<host>:<port>/ Connected to: <host> at port <port> 5 - tcp://<host>:<port>/ [0x004048c5]> =<5 cmd...
=< command will send the output from the execution of
cmd to the remote connection number N (or the last one used if no id specified).
