SUSE Linux Enterprise Server 11 Service Pack 3 (SLES 11 SP3)

SUSE Linux Enterprise Server 11 Service Pack 1 (SLES 11 SP1)


Trying to register fails with unknow CA certificate error:
linux:/ # suse_register -a regcode-sles=<your_regcode> -a email=<your email> -L /root/.suse_register.log
ERROR: Peer certificate cannot be authenticated with known CA certificates: (60)


Change configuration of the Intrusion Detection System (IDS) to allow SSLv3 connections.


suse_register tries SSLv3 connect to Novell Customer Center which then initiate TLS handshake. Intrusion Detection System prevents SSLv3 connect attempt.

Additional Information

With IDS denying SSLv3 connection the result is errno 104 which means connection reset:
linux# openssl s_client -connect |tee logfile.txt

Trying TSL1 will work fine:
linux# openssl s_client -connect -tls1
