Hello,
I'm playing with a networked remsim setup. The remsim server, sim card
reader and banks daemon sit on a RPI (rpi-cardem-1), while the client
(and the simtrace2) sit on a different RPI (rpi-cardem-2).
The client is started like this, and keeps producing this output:
root@rpi-cardem-2:~# osmo-remsim-client-st2 --server-ip remsim-server
--server-port 9998 --client-id 1 --client-slot 1 --usb-vendor 1d50

This looks like bankd sends back an wrong state/event:
DRSPRO ERROR ../rspro_client_fsm.c:297
RSPRO_CLIENT(bankd){REESTABLISH}: Event SRVC_E_KA_TERMINATED not
permitted
On the bankd side, this is what I get:

It searches for the reader but returns error -2.

Now - if it's using a regex to search for the reader string, the fact
that my reader has [] and () in it will break the regex search, right?
I've changed /etc/osmocom/bankd_pcsc_slots.csv, and set just:
"1","1","SCM Microsystems Inc. SCR 3310"
as the reader name/mapping, leaving out the special characters, and it
started ok.
I suggest making a note of this in the documentation, that special
characters in the reader name are checked via regular expressions.
Cheers!

The example config file snippet just below it also contains \[ style escaping

Thanks, I had missed that! Perhaps it would be helpful for bankd to
explicitly log that no reader was found according to the regex - in my case
the problem wasn't obvious, and the client would keep retrying in a loop.

I just checked the source code, and it contains the following log statement:
LOGW(worker, "Error: Cannot find PC/SC reader/slot matching using regex
'%s'\n", worker->reader.name)
So you should have this "Cannot find PC/SC reader/slot matching ..." message in
your log files.
Please let us know if the message did not show up, so we can investigate why it is not
printed.
