Pau Espin Pedrol pespin at sysmocom.deHi,
I would say the RLCMAC side looks fine. It looks like the SGSN is
rejecting the ATTACH REQUEST. You may have a misconfiguration in the
encryption config of osmo-sgsn?
Unfortuantely, your pcap doesn't contain the contents of the Gb
interface ("gprs-ns" filter in wireshark), so it's difficult to say
what's going on.
Please share a pcap containing gprs-ns (PCU<->SGSN) and gtp
(SGSN<->GGSN) packets in order to find out what's going on. Share also a
log file of osmo-sgsn (or use gsmtap log) with debug enabled to find out
why is the SGSN rejecting it.
Regards,
Pau
