# Advanced Client Management
|
|
|
|
## Client Configuration Mode
|
|
|
|
The [`ovpn_getclient`](/bin/ovpn_getclient) can produce two different versions of the configuration.
|
|
|
|
1. combined (default): All needed configuration and cryptographic material is in one file (Use "combined-save" to write the configuration file in the same path as the separated parameter does).
|
|
2. separated: Separated files.
|
|
|
|
Note that some client software might be picky about which configuration format it accepts.
|
|
|
|
## Batch Mode
|
|
|
|
If you have more than a few clients, you will want to generate and update your client configuration in batch. For this task the script [`ovpn_getclient_all`](/bin/ovpn_getclient_all) was written, which writes out the configuration for each client to a separate directory called `clients/$cn`.
|
|
|
|
Execute the following to generate the configuration for all clients:
|
|
|
|
docker run --rm -it -v /tmp/openvpn:/etc/openvpn kylemanna/openvpn ovpn_getclient_all
|
|
|
|
After doing so, you will find the following files in each of the `$cn` directories:
|
|
|
|
ca.crt
|
|
dh.pem
|
|
$cn-combined.ovpn # Combined configuration file format. If your client recognices this file then only this file is needed.
|
|
$cn.ovpn # Separated configuration. This configuration file requires the other files ca.crt dh.pem $cn.crt $cn.key ta.key
|
|
$cn.crt
|
|
$cn.key
|
|
ta.key
|
|
|
|
## Revoking Client Certificates
|
|
|
|
Revoke `client1`'s certificate and generate the certificate revocation list (CRL):
|
|
|
|
docker run --rm -it --volumes-from $OVPN_DATA kylemanna/openvpn easyrsa revoke client1
|
|
docker run --rm -it --volumes-from $OVPN_DATA kylemanna/openvpn easyrsa gen-crl
|
|
|
|
The OpenVPN server will read this change everytime a client connects (no need to restart server) and deny clients access using revoked certificates.
