## First step
|
|
|
|
```
|
|
service ipsec stop
|
|
service xl2tpd stop
|
|
rm -rf /usr/local/sbin/ipsec /usr/local/libexec/ipsec
|
|
rm -f /etc/init.d/ipsec /lib/systemd/system/ipsec.service
|
|
```

|
## Second step
|

|
|
### Ubuntu/Debian
|
|
|
|
`apt-get remove xl2tpd`
|
|
|
|
### CentOS/RHEL
|
|
|
|
`yum remove xl2tpd`
|
|
|
|
## Third step
|
|
|
|
### Ubuntu/Debian
|
|
|
|
Edit `/etc/iptables.rules` and remove unneeded rules.
|
|
Your original rules (if any) are backed up as `/etc/iptables.rules.old-date-time`.
|
|
In addition, edit `/etc/iptables/rules.v4` if the file exists.
|
|
|
|
### CentOS/RHEL
|
|
|
|
Edit `/etc/sysconfig/iptables` and remove unneeded rules.
|
|
Your original rules (if any) are backed up as `/etc/sysconfig/iptables.old-date-time`.
|
|
|
|
## Fourth step
|
|
|
|
Edit `/etc/sysctl.conf` and remove the lines after `# Added by hwdsl2 VPN script`.
|
|
Edit `/etc/rc.local` and remove the lines after `# Added by hwdsl2 VPN script`. DO NOT remove `exit 0` (if any).
|
|
|
|
## Optional
|
|
|
|
Note: This step is optional.
|
|
|
|
Remove these config files:
|
|
|
|
* /etc/ipsec.conf
|
|
* /etc/ipsec.secrets
|
|
* /etc/xl2tpd/xl2tpd.conf
|
|
* /etc/ppp/options.xl2tpd
|
|
* /etc/ppp/chap-secrets
|
|
* /etc/pam.d/pluto
|
|
* /etc/sysconfig/pluto
|
|
* /etc/ipsec.d (directory)
|
|
|
|
Copy and paste for fast removal:
|
|
|
|
```
|
|
rm -f /etc/ipsec.conf /etc/ipsec.secrets /etc/xl2tpd/xl2tpd.conf /etc/ppp/options.xl2tpd \
|
|
/etc/ppp/chap-secrets /etc/pam.d/pluto /etc/sysconfig/pluto
|
|
rm -rf /etc/ipsec.d
