Zdravim vespolek a prosim o nakopnuti spravnym smerem.
Presel jsem z CentOS 7 na Fedora 33 a relativne uspesne si zmigroval sluzby a nastaveni.
Jednou z tech sluzeb je hostapd.
Postup:
1) nainstaluji
hostapd2) vyjmu wifi interface ze spravy
NetworkManageru3)
systemctl mask wpa_supplicant (mozna je to redundantni k bodu 2 - jednalo se o to, ze wpa_supplicant prilezitostne chtel provadet scan siti v okoli pri jejich predani NM, coz spolehlive shodilo veskerou komunikaci hostapd)
4) zkopiruju svuj
fungujici config do
/etc/hostapd/hostapd.conf5)
systemctl start hostapd => spusti se
hostapd /etc/hostapd/hostapd.conf -P /run/hostapd.pid -B, k AP se pripojim, v
systemctl status hostapd vidim uspesne pripojeni. Potud vsechno super.

A ted problem.
6)
systemctl enable hostapd (aby mi hostapd nabehnul pri restartu sam)
7)
reboot =>
hostapd se sice spusti (se stejnymi parametry, pod rootem, ... jako pri rucnim spusteni), ale neni mozne se k nemu pripojit.
Wireshark ukazuje akorat EAPOL pakety 1 a 2 a komunikace pak vytuhne.
systemctl status hostapd ukaze:

4 pokusy, nakonec timeout, disconnect, konec.
Vtipne je, ze kdyz udelam:
systemctl stop hostapda zkusim jej pustit znovu rucne, tak to nefunguje taky.
Udelam
systemctl disable hostapd, reboot,
systemctl start hostapd - najednou kouzelne funguje.

V cem muze byt bota?
Napada mne jedine, ze by to mohlo mit co delat s existenci prazdneho bridge br_wifi (jako pokus spustit hostapd driv, nez br_wifi existuje... to by ale, predpokladam, neco zarvalo?).
Google vesmes mlci, tuhle exotiku holt neprovozuje kazdej druhej.
Muzu nejak zkusit start hostapd jako aktivni sluzby oddalit, treba klidne az minutu po bootu, pro overeni nejake zavislosti?
