[SOLVED] VPN automatically on and ip a shows nothing

bwrsandman · 2021-03-23 14:15:43

Some time last week I was attempting to get mozilla vpn working using both the mozwire and mozillavpn packages.
I was not able to get the result I liked and put it aside.
Sometime this week I noticed that when I check my IP address it is set to another location, which would make sense if I was connected to a vpn.
Another thing I noticed is that ip addr returns without error but with no output, not even a loopback.
The ip addr command seems to have stopped displaying output when I was setting up wireguard using wg-quick.

This happens at boot automatically and I don't know how to disable it. I tried uninstalling mozwire, mozillavpn, wireguard. I tried removing their configs, services. I even tired uninstalling network manager.

What could cause this? How do I get ip addr working again? How do I disable this VPN?

Check if there is a systemd service / timer , enabled to start at boot using:

systemctl list-unit-files --state enabled

Is there anything here that seem off?

$ systemctl list-unit-files --state enabled

Only service file that i think could be the culprit is NetworkManager.service ,
Have a look in "/etc/NetworkManager/conf.d/" for any config files that are related to the mozilla VPN.

bwrsandman · 2021-03-23 15:28:59

I cleared my NetworkManager configuration so these are the only files left

# find /etc/NetworkManager
/etc/NetworkManager
/etc/NetworkManager/system-connections
/etc/NetworkManager/system-connections/MY_PRIVATE_SSID.nmconnection

Only other things i can think of is check that /etc/NetworkManager/system-connections file and check /etc/network/interfaces

With regards to the ip addr command, i've no clue why it would suddenly show no output.

bwrsandman · 2021-03-23 15:37:35

I don't have a /etc/network/interfaces or a /etc/network directory.

# cat /etc/NetworkManager/system-connections/MY_PRIVATE_SSID.nmconnection
[connection]
id=*****
uuid=*****
type=wifi
interface-name=wlo1
permissions=

[wifi]
mac-address-blacklist=
mode=infrastructure
ssid=*****

[wifi-security]
auth-alg=open
key-mgmt=wpa-psk
psk=*****

[ipv4]
dns-search=
method=auto

[ipv6]
addr-gen-mode=stable-privacy

[proxy]

I think the ip addr command stopped displaying output when I was setting up wireguard using wg-quick.

cmm11 · 2021-03-23 15:39:46

There's nothing in that config file that is related to the vpn so that's a pity.
Hopefully someone else will have other ideas, or you could try get support from mozilla.

I've ruled out GDM, this happens even if it's disabled.

Here's my network manager details

I'm not too sure what wifi-p2p is

It seems my iproute2 package was broken. The files were there but the package wasn't installed. Reinstalling iproute2 has fixed the ip addr command.

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp61s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 30:9c:23:91:50:66 brd ff:ff:ff:ff:ff:ff
3: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 0c:54:15:44:17:b8 brd ff:ff:ff:ff:ff:ff
    altname wlp0s20f3
    inet 192.168.1.6/24 brd 192.168.1.255 scope global dynamic noprefixroute wlo1
       valid_lft 85334sec preferred_lft 85334sec
    inet6 fe80::72ee:420a:779d:ca10/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

Strangely enough, my WAN ip address comes back normal.

Geolocation is not perfect and the location databases may be wrong. Personally I'd prefer it if they were even more unreliable.

Your wireless interface has a local IP, not a WAN IP. Only your router has a WAN IP. (It would be a bit different with IPv6, then all devices would get an IP in your global prefix). If you use a VPN or not can be seen by comparing the WAN IP displayed in your router with an internet service.

I was checking my external IP with DDG and it was displaying a different country before reinstalling iproute2 and now it is displaying the correct one. The only explication I would have is that somehow I got these files overwritten by either mozwire, mozillavpn, wireguard or something else. I don't know how if iproute2 is able to connect to a VPN...
