pptp tunneling over terminal [SOLVED]

erfanjoker · 2019-09-11 10:58:42

Hi, i have a PPTP VPN configured in NM using NM Xfce Applet wich seems to work fine and tunnels my network in GUI Apps

but whenever i enter a command in terminal, my transfered data via terminal is not getting tunneled (i get access denied msg thanks to my conutry)

im looking for a command to run my commands under a PPTP tunneling in terminal , maybe an alternative to torsocks for my PPTP vpn

Could you please show your relevant network config?

ip link
ip addr
ip route

I suspect your routing config is incorrect. Please check if your target address is going through the pptp device and if not either add an entry or change the default route.

Thanks for your reply, here are the outputs of the commands :

Please someone correct me if I am wrong, but multiple default gateways result in random selection of the interface unless you define them in multiple routing tables. In your case a solution would be to remove the one provided by your local interface which should not be used:

ip route del default via 192.168.1.1 dev enp4s0

PPTP Tunneling works fine for GUI Apps but not working in terminal commands, i dont guess its about interfaces or etc

Swiggles · 2019-09-11 18:38:18

So, did you test it?

Also show a tracepath for the address you try to reach:

tracepath -4b $target

Also show the output of

ip rule
sysctl net.ipv4 | grep [^a]rp_filter

Disconnect from your vpn and run

ip monitor

Reconnect and provide the output as well.

Final warning.

works fine for GUI Apps but not working in terminal commands

~ ·> GUI Apps
zsh: command not found: GUI
~ ·> terminal commands
zsh: command not found: terminal

The separation you claim does not exist. There's no fundamental network I/O difference between a generic CLI and a generic GUI process, so please be more specific on the test cases.

Where your network traffic goes is determined by the destination...IOW everything is a terminal app.

It's a routing issue...
