Hi, can you please record and send a pcap file while trying to attach? Make sure you are using osmo-bts-trx and osmo-pcu master (please provide output wyou get with "--version"). Also make sure to enable GSMTAP in both osmo-pcu and osmo-bts-trx. Also please enable "gsmtap log" with "logging level set-all info" for osmo-pcu, so that everything end sup in the pcap file.

Make sure you are using osmo-bts-trx and osmo-pcu master (please provide output wyou get with "--version"). Also make sure to enable GSMTAP in both osmo-pcu and osmo-bts-trx. Also please enable "gsmtap log" with "logging level set-all info" for osmo-pcu, so that everything end sup in the pcap file.

Make sure you are using osmo-bts-trx and osmo-pcu master (please provide output wyou get with "--version"). Also make sure to enable GSMTAP in both osmo-pcu and osmo-bts-trx.

Hi, 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.

Make sure you are using osmo-bts-trx and osmo-pcu master (please provide output wyou get with "--version"). Also make sure to enable GSMTAP in both osmo-pcu and osmo-bts-trx.
