Installing google-authenticator on a Debian behind another Debian firewall in a very restricted configuration on connectivity (NetinVM, a virtual machine constellation inside a VM)
Installation goes OK Synchronisation with phone app OK SSH connection ask for codes OK but phone generated codes do NOT work tried with Emergency scratch codes, it goes OK
I analyse traffic on server (machine with ssh and g-auth), client, and firewall machine, no one of them shows sings of any intentions of connection to google servers. But I presume it should exist, isn't it ?
Any help on this matter ?
Package: apt-get install libpam-google-authenticator
Not sure if useful, but. As creating the synchronisation with mobile, doesn't matter if doing with the QR or entering manually the long secret key, the verification code is never asked/used.
Sample:
Your new secret key is: ABCDEFGHIJKLMNOP
Your verification code is 123456
Your emergency scratch codes are:
12345678
90123456
78901234
56789012
34567890
