        TLSv1/SSLv3 ECDHE-RSA-AES256-GCM-SHA384  zlib compression
        0 packets remaining to print of 0 total
  • Add support for new channels: In 1.2.0 we added support for DNS Errors and NXD Channels via etc/fields.

  • Add pidfile support for sratunnel: We added an option to sratunnel to allow the user to specify a pidfile. This allows for easy management of daemonized sratunnel processes.

  • Updated help: The help has been updated to be a bit clearer and easier to read.

  • Fix print_sie_newdomain(): There was a NULL pointer dereference that resulted in a crash. The bug was triggered when a pathological newdomain SOA message was printed in “non-verbose” mode.

  • Fix axa_str_to_cidr(): Patched to remove a false negative error condition.

  • Fix axa_get_token(), axa_vlog_msg(), dns_to_key(), trie_free()
    Multiple corner-case bugs fixed.

Stay tuned for further updates!
