# Manage VPN Users

|
By default, a single user account for VPN login is created. If you wish to add, edit or remove users, read this document.
|
|
|
|
First, the IPsec PSK (pre-shared key) is stored in `/etc/ipsec.secrets`. To change to a new PSK, just edit this file.
|
|
|
|
```bash
|
|
<VPN Server IP> %any : PSK "<VPN IPsec PSK>"
|
|
```
|
|
|
|
For `IPsec/L2TP`, VPN users are specified in `/etc/ppp/chap-secrets`. The format of this file is:
|
|
|
|
```bash
|
|
"<VPN User 1>" l2tpd "<VPN Password 1>" *
|
|
"<VPN User 2>" l2tpd "<VPN Password 2>" *
|
|
... ...
|
|
```
|
|
|
|
You can add more users, use one line for each user. DO NOT use these characters within values: `\ " '`
|
|
|
|
For `IPsec/XAuth ("Cisco IPsec")`, VPN users are specified in `/etc/ipsec.d/passwd`. The format of this file is:
|
|
|
|
```bash
|
|
<VPN User 1>:<VPN Password 1 (hashed)>:xauth-psk
|
|
<VPN User 2>:<VPN Password 2 (hashed)>:xauth-psk
|
|
... ...
|
|
```
|
|
|
|
Passwords in this file are salted and hashed. This step can be done using e.g. the `openssl` utility:
|
|
|
|
```bash
|
|
# The output will be <VPN Password 1 (hashed)>
|
|
openssl passwd -1 "<VPN Password 1>"
|
|
```
|
|
|
|
When finished making changes, run these commands or reboot your server.
|
|
|
|
```bash
|
|
service ipsec restart
|
|
service xl2tpd restart
|
|
```
