["Andreas Wallberg (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/VFS-412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490309#comment-13490309 ] 

Andreas Wallberg commented on VFS-412:
--------------------------------------

According to RFC 2228, (http://www.ietf.org/rfc/rfc2228.txt) that introduced PROT command, "The PBSZ command must be preceded by a successful security data exchange.". I think this means that "PBSZ 0" must be issued before "PROT P".
