ERROR: Linux route delete command failure
-
So I set up OpenVPN following this guide, https://www.highlnk.com/2013/12/configuring-openvpn-on-pfsense/
For Tunnel Network, I put "10.0.8.0/24" and I set local network to "192.168.10.0/24" (My LAN interface already uses subnet 192.168.10 …so I am not sure if I that will cause a conflict). Everything else is set up in the way of the guide except for the Dynamic DNS part (I am using same static IP assigned to pfsense WAN...that shouldnt cause a conflict I would think). Now the first time I tried connecting I used this command on my arch linux computer "sudo openvpn --config myconfignamehere.ovpn" and it worked out fine, I used wireshark to check if my data was encrypted and I used the route command to check my IPs and gateways, no errors in terminal either. Now its been a few days (Only I connect) when I use the same command I still get connected to the VPN and encryption is fine but I get this error message
ERROR: Linux route delete command failed: external program exited with error status: 2Here is the full output when running the command I listed above,

Anyway, whats the fix?

Looks like your linux already has that ip address assigned to an interface. Is OpenVPN running twice?
Did you turn it off and back on again?

No openvpn is not running twice, I have tried resetting the machine several times and same problem, this happens on my desktop which runs same distribution of linux on laptop also.

Post the routing table of the computer doing this.

um..I don't really know what that is lol. Are you referring to /etc/iproute2/rt_tables ?

That looks fine. What's not working?

everything seems to be working, it's just that the error (in op) I got in the terminal was of concern to me, I thought something was wrong either on client or server end.

Linux or OpenVPN forum might get you an answer.

alright I will give it a shot, thank you for assisting me though!

You know what. I think a lot of people get strange errors at that point. Not really an error but OpenVPN trying to do something that's already been done or something.
