How to configure Username/Password

[77wisher77]

There's no documentation for how to setup the username and password for clients to connect with, and I have been struggling to figure this out

as per the documentation my options.sstpd has require-mschap-v2

[sorz]

Refer to pppd's document. For MSCHAPv2, the username and password are usually written on /etc/ppp/chap-secrets.

[77wisher77]

Ok, so my /etc/ppp/chap-secrets looks like

<username> SSTP <password> *

however i get this in the console of the server when i try and connect

WARNING Received errors from pppd
WARNING b"usr/sbin/pppd: The remote system is required to authenticate itself\n/usr/sbin/pppd: but I couldn't find any suitable secret (password) for it to use to do so.\n

I'm pretty sure im doing something wrong in the chap-secrets file

here's an image of my entire setup:

[sorz]

I'm not sure what the server name in chap-secrets should be. Try replace SSTP with *? Like <username> * <password> *

[77wisher77]

ok so setting server to either * or sstpd results in
VERBOSE Raw data: xxx
Segmentation fault (core dumped)

and then the sstpd command ends

[77wisher77]

running coredumpctl info xxx finds this:

Seems to be related to #46 same error

I'm running Arch linux, when installing python311 from the aur (before sstp-server) i get the error -bash: sstpd: command not found
I get the following error when trying to makepkg -sirc sstp-server: ModuleNotFoundError: No module named 'setuptools

given the solution was to upgrade python I am unsure how to proceed

Edit: running python3 -m ensurepip seemed to the sstpd command to run again, however i get the same Segmentation fault (core dumped) error when running python311 (3.11)

[77wisher77]

Update, AUR python39 works!

Arch users Don't forget to symlink /usr/bin/python3.9 to /usr/bin/python3

Now I have an issue with the default gateway being 0.0.0.0, which stops internet access on clients, I'll open a new issue for that
