[Support] PiVPN + Client from RPi/Ubuntu/Microtik not working #1078

Closed crystal-way closed 4 years ago

crystal-way commented 4 years ago

In raising this issue, I confirm the following:

{please fill the checkboxes, e.g: [X]}

I have runing PiVPN (OpenVPN v.2.4.7) on PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10". I have NO problems connecting to it from iPAD using OpenVPN app also NO problems connecting to it from Mac OS/Tunnelblick.

I have running two other machines with Ubuntu AND Raspbian (both with installed PiVPN as SERVER) and as server they work great. But i CAN'T connect from these two machines to the first one. Connection is successful, but i can't even ping a server. The logs on the server does not show anything bad. I've read hundreds of posts, tried many different iptables (client side) checked firewall also on client site (it is disabled) and no success to even ping the server. While as mentioned before, from ipad and tunnelblick - everything works fine.

Then i've decided to go for workaround and connect to the first machine using Mikrotik router hAP ac2. But this device could not even connect to PiVPN server. I only get errors on server side: tls-crypt unwrap error: packet too short TLS Error: tls-crypt unwrapping failed from Fatal TLS error (check_tls_errors_co), restarting SIGUSR1[soft,tls-error] received, client-instance restarting

Have no idea what to try else. from iPAD and Mac OS , everything is fine, from Ubuntu, Raspbian and Mikrotik - FAILS only.

Have you searched for similar issues and solutions?

(yes/no / which issues?)

yes

Have you taken any steps towards solving your issue?

  read as much post and forums as i found

At least one solution would solve my problems. I would be happy to access PiVPN server from Ubuntu or RPi or Mikrotik. I can access it from Mac OS and iPAD, but this does not solve my problem.

Thank you.

crystal-way commented 4 years ago

While posting this topic, i've noticed that in the DEBUG report it is written: IPv4addr=192.168.88.42 IPv4gw=192.168.88.1

These are old IP's from the network where RPi and PiVPN where installed. Now it is running on the ip address 192.168.1.80 with gw 192.168.1.1, but as mentioned in the begining i can access over VPN PiVPN server with no problems.

orazioedoardo commented 4 years ago

There are a lot of errors in the debug log, can you show the output of these (firewall and openvpn status)?

sudo iptables -S
sudo iptables -t nat -S
sudo systemctl restart openvpn
tail -n 20 /var/log/openvpn.log

On which machine i should export log's? Ubuntu or RPI openvpn client, that connect but have no ping?

or RPi openvpn server?

orazioedoardo commented 4 years ago

On the RPI openvpn server

crystal-way commented 4 years ago

Please see all information. I've got it while connected from Mac OS to RPi server. This connection as mention before works great (except i can't access other devices on the destination LAN, only server, but this is not the first priority question). Thank you.

Run pivpn -d and say Y to fix iptables rules.

crystal-way commented 4 years ago

Should i make "Y" for all 3 iptables fix'es and 4th "Y" for restart?

[OK] IP forwarding is enabled :: [ERR] Iptables MASQUERADE rule is not set, attempt fix now? [Y/n] n :: [ERR] Iptables INPUT rule is not set, attempt fix now? [Y/n] n :: [ERR] Iptables FORWARD rule is not set, attempt fix now? [Y/n] n :: [OK] OpenVPN is running :: [OK] OpenVPN is enabled (it will automatically start on reboot) :: [ERR] OpenVPN is not listening, try to restart now? [Y/n] n

orazioedoardo commented 4 years ago

If the debug reports that OpenVPN is not listening, say Y to that too. Then post pivpn -d again.

crystal-way commented 4 years ago

I've tried a few time, everytime it says that OpenVPN ins not listening (but it's actually does, as i'm connecting to it).

Also why it's remember old IP's:

IPv4addr=192.168.88.42 IPv4gw=192.168.88.1

Currently it is no the 192.168.8.0 network with the 192.168.8.222 IP address.

Also why it's remember old IP's:

Old IPs at the time you installed.

I've tried a few time, everytime it says that OpenVPN ins not listening (but it's actually does, as i'm connecting to it).

How about netstat -uanpt | grep openvpn

P.S. I also formatted your previous comments and removed client IPs. Next time use the insert code button to post code otherwise it is hard to read.

crystal-way commented 4 years ago

Thank you. I've seen that it looks ugly, but could not find how to sort it out. Should i change somewhere those old IP's that left from installation or it does not matter? please see answer from:

netstat -uanpt | grep openvpn

`sudo netstat -uanpt | grep openvpn tcp 0 0 0.0.0.0:28282 0.0.0.0:* LISTEN 24187/openvpn
tcp 0 142 192.168.8.222:28282 34.14.111.89:51879 ESTABLISHED 24187/openvpn

`

orazioedoardo commented 4 years ago

Wait, why the server is TCP but the client is UDP, did you change that?

If you want to use UDP, edit the config sudo nano /etc/openvpn/server.conf and replace proto tcp with proto udp, then restart sudo systemctl restart openvpn.

crystal-way commented 4 years ago

Originally it was installed as UDP. With this configuration also i could make connection to server from RPi and Ubuntu, but could NOT ping the server (Mac OS and ipad could connect/ping/access).

As i need to make rsync between these two machines, i've changed manually server to TCP, as well as all my clients to TCP. After this change, Mac OS and iPAD still can connect and access server. RPi and ubuntu also still can connect to server (over TCP), but can't ping or access server.

So i believe this does not have anything with the issue, as over UDP i had same problem.

orazioedoardo commented 4 years ago

i've changed manually server to TCP

Ok, that's the reason why the debug says it's not listening, it expects udp but actually is tcp.

RPi and ubuntu also still can connect to server (over TCP), but can't ping or access server.

Try not that we fixed the firewall rules.

crystal-way commented 4 years ago

Same story. From iPAD i can connect to VPN and PING + SSH to server. From Ubuntu. i can connect to VPN, but no ping, no SSH to server :|

orazioedoardo commented 4 years ago

From Ubuntu. i can connect to VPN, but no ping, no SSH to server :|

Can you post the openvpn log when you connect, on the client and on the server (remove client IPs if you want). Is the Ubuntu PC in the same network as the pivpn or on a different network?

crystal-way commented 4 years ago

Strange thing. On both clients there are no log's. /var/log/openvpn.log is empty. nothing in there. but the openvpn.log.1 contains older data. Maybe for the client i should see other file?

While server log is here:

orazioedoardo commented 4 years ago

I see nothing wrong in the log. What about this question:

Is the Ubuntu PC in the same network as the pivpn or on a different network?

crystal-way commented 4 years ago

Ubuntu PC and RPi with client are on different network. RPi pivpn server on another.

orazioedoardo commented 4 years ago

I don't really know how to help at this point, most likely not PiVPN related. If you can ssh from iPad but not from Ubuntu, it should be a client side issue. What error you you get when connecting via ssh, connection refused, no route to host, timeout?

crystal-way commented 4 years ago

@orazioedoardo thank you for your time and help. I've made a work around. Have installed a new ubuntu machine, connected to RPi server, all works fine. As this is one time project i will be happy with work around.

Have a nice life! ;)
