Hello
ı am using openvpn server on Linux.i have created vpn client successfully.
Open Vpn Users can succesfully connect to My Open Vpn server .
But i can not configured "ipp.txt" file.
For Example ;
for client1;
cat /etc/openvpn/ccd/client1
ifconfig-push 10.2.1.9 10.2.1.10
There is no problem on the top line.the client1 assigned 10.2.1.9

i added the line in /etc/openvpn/ipp.txt
client1,10.2.1.9
There is no problem on the top line.

When i restarted openvpn Server,the client didnt re-connect.

i looked ip.txt file.i was very amazing,because ipp.txt file is emtpy ?

Shortly,When i restarted openvpn Server,ipp.txt file is empty.
My server.conf is

port 1194
proto tcp
dev tun
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/gwfiber.crt
key /etc/openvpn/easy-rsa/keys/gwfiber.key
dh /etc/openvpn/easy-rsa/keys/dh2048.pem
server 10.2.1.0 255.255.255.0
push "route 192.168.3.0 255.255.255.0"
push "route 192.168.55.0 255.255.255.0"
client-config-dir /etc/openvpn/ccd
ifconfig-pool-persist /etc/openvpn/ipp.txt 10
push "dhcp-option DNS 8.8.8.8"
client-to-client
keepalive 10 120
cipher BF-CBC

you cannot use this file to save settings.

Use the CCD file as you have done.

Traficc thank you very much for your answer,but the problem is not solved.
i moved ipp.txt file in ccd folder.
And than i edited ifconfig-pool-persist /etc/openvpn/ccd/ipp.txt
root@xxxxr:/etc/openvpn/ccd# ls -l
-rw-r--r-- 1 root root 67 Mar 25 13:40 client1
-rwxrwxr-x 1 root root 0 Mar 26 16:45 ipp.txt
i added client1,10.2.1.9 in ipp.txt file.
i restarted openvpn server.But the file was again empty.

When i restarted to my open vpn server,my openvpn server log is

You cannot add "client1,10.2.1.9" to this file!

Use this file:

secoonder wrote:root@xxxxr:/etc/openvpn/ccd# ls -l
-rw-r--r-- 1 root root 67 Mar 25 13:40 client1

Add:

Code: Select all

ifconfig-push 10.2.1.9 10.2.1.10

exactly as you have done ..

Traficc thank you for your answer.
I have already written it
root@xx:/etc/openvpn/ccd# more client1
ifconfig-push 10.2.1.9 10.2.1.10

i noticed someting.When client1 connect from windows computer,it was no problem.
(When i restarted server,the client1 auto reconnect server.)
But client1 cannot reconnect from ubuntu.

was it related this line in server.conf?

Code: Select all

# It's a good idea to reduce the OpenVPN
# daemon's privileges after initialization.
#
# You can uncomment this out on
# non-Windows systems.

;user nobody
;group nogroup
