my question is about WPA3 on 20.04 and the corresponding journal output for the NetworkManager.
When I connect to a WPA3 Personal network, I see the following lines:
key_mgmt sae ft-sae (which is ok)
auth_alg open
The part open confuses me, since the info I can find describes open only with the old WEP Nevertheless the wpa_supplicant.conf states that if auth_alg is not set, the default is OPEN with LEAP enabled if set.
# auth_alg: list of allowed IEEE 802.11 authentication algorithms
# OPEN = Open System authentication (required for WPA/WPA2)
# SHARED = Shared Key authentication (requires static WEP keys)
# LEAP = LEAP/Network EAP (only used with LEAP)
# If not set, automatic selection is used (Open System with LEAP enabled if
# LEAP is allowed as one of the EAP methods).
When I check the wpa_cli output for the corresponding device with
wpa_cli -i DEV status
I see the following output:
key_mgmt=SAE
pmf=1
mgmt_group_cipher=BIP
sae_group=19
wpa_state=complete
ieee80211ac=1
Which leads me to the conclusion that the WPA3 connection was correctly established, also the AP shows the device as WPA3 connected device.
The point I don't get and what concerns me is, why auth_alg open appears in NetworkManager for WPA3, which is in fact not present with WPA2.
Side info:
- Connection was purely setup with GUI, no modification on .confs
- Behaviour can be seen on mulitple connections with WPA3 APs
- Used Kernel 5.13
Any suggestions or experiences from your side? Same behaviour?
Thank you for any help or experience from your side!
