Hi all,
I've a _working_ server-client setup (tap + L2 bridge; server-bridge with
on-lan DHCP), where the pam-auth plugin does the authentication (OTP with
static-challenge, works OK). However, if I disable the plugin authentication
and enable 'management-client-auth' (nothing else chages in either of the
configs), the client fails to establish the data channel (authentication
works, control channel is ok).
In the server logs I see the following (with mgmt auth):
mysecretuser/CLIENT_PUBLIC_IP:63979 TLS Warning: no data channel send key
available: [key#0 state=S_ACTIVE id=0 sid=f1576b13 7324afbe] [key#1
state=S_UNDEF id=0 sid=00000000 00000000] [key#2 state=S_UNDEF id=0
sid=00000000 00000000]
mysecretuser/CLIENT_PUBLIC_IP:63979 MULTI: C2C/MCAST/BCAST
and a lot of these:

In the client log I see the following (nothing special):

What can be the matter? Do I need to supply anything else via mgmt@server
other than 'client-auth ID ID' upon successful authentication?
(authentication script is a python script written by me, based on
selvanair's CR demo)
Thanks,
Tom
