I was unable to get connman to make a vpn connection to my work. This is a
simple pptp vpn connection on a Laptop running Arch Linux with Gnome.
Struggled for a few hours and nothing. I enabled NetworkManager and in a
few seconds, voila! it worked.
I like connman/iwd. I use it on my Raspberry Pis and want to use
connman/iwd on my laptop. It works great on the laptop for the wifi and
ethernet connections, but I need vpn as well. I know it can do it, but the
docs are a bit sketchy and I was unsuccessful. When I compare my log of a
successful connection with NetworkManager and my failed connection with
connman, I cannot see anything strange.
How does one actually enable more debugging? The *.config file can have a
PPTP.Debug=, but it is unclear what we should put there? 1,2,3? Full? Max?
Verbose? The man page is unclear.
In Network Manager, my relevant settings are:
[vpn]
domain=work
gateway=vpn.work.com
mppe-stateful=yes
password-flags=2
refuse-chap=yes
refuse-eap=yes
refuse-mschap=yes
refuse-pap=yes
require-mppe=yes
user=username
for connman-vpn, I tried this:
[provider_work]
Type=PPTP
Name=work
Host=vpn.work.com
Domain=work
PPTP.User=username
PPPD.RefuseCHAP=true
PPPD.RefuseEAP=true
PPPD.RefuseMSCHAP=true
PPPD.RefuseMSCHAPv2=false
PPPD.RefusePAP=true
PPPD.ReqMPPE=true
PPPD.ReqMPPEStateful=true
The log shows similar responses, but then disconnects.
The only error I get is:
"Non-zero Async Control Character Maps are not supported!"
Then a disconnect.
Also, I think it would help to get this package more widely used if it had
a current, viable gnome extension. This one no longer works (at least with
Arch) and is abandoned since 2016.
https://extensions.gnome.org/extension/981/connman-extension/
I have connman-gtk and cmst installed and both have some shortcomings. It
would be awesome if I could edit the config in the applet...
Thanks for looking,
Keith
