No private IP detected issueCreated on 2022/10/14,
cells, you see this warning in your logs:
Warning: no private IP detected for binding broker. Will bind to <YOUR PUBLIC IP ADDRESS>, which may give public access to the broker.
You should solve this issue by adding a virtual NIC on your machine or you might be at risk (depending onn how secure is your network).
Internally, Pydio Cells is implemented with a microservice oriented architecture: each simple feature is implemented as an independant brick that exposes a set of internal APIs inside Cells.
All microservices communicate together via gRPC, a HTML2 based protocol. It is important that this communication happens on a private network for better security.
On single instance servers, this is done by using a private IP of the server.
How to fix
There are many ways to declare a private virtual interface. A few examples:
If you have
docker installed on your machine, launch the service:
the docker daemon creates a virtual private network that can be used by Cells.
On Debian like
If your main interface is called
eno1, make a backup of your
/etc/network/interfaces file and append this:
# virtual IP on eno1 auto eno1:0 iface eno1:0 inet static address 10.0.0.1 netmask 255.255.255.0 network 10.0.0.0 broadcast 10.0.0.255
From your comand line, mount the virtual NIC and list all:
sudo ifup eno1:0 sudo ip address
On RHEL like
Your main interface is called
eth0, adapt otherwise.
sudo tee /etc/sysconfig/network-scripts/ifcfg-eth0:0 << EOF DEVICE="eth0:0" ONBOOT="yes" BOOTPROTO="static" IPADDR="10.0.0.1" NETMASK="255.255.255.0" BROADCAST="10.0.0.1" EOF # Start the interface and check new IP sudo ifup eth0:0 sudo ip address
