MS-CIFS says this in Appendix A: <186> Section 3.2.6.1: Windows NT and Windows 98 CIFS clients periodically scan for any commands that have not completed. The default scanning period is 30 seconds. If there are outstanding commands that have exceeded the Client.SessionTimeoutValue, an SMB_COM_ECHO (section 2.2.4.36) is sent to determine whether or not the connection has been lost. The client closes the connection only if there is no response to the echo request. My questions are as follows: 1) If the server is responding to the echo requests, does the client still eventually return an error to the application or does it wait indefinitely for the response? 2) If it returns an error to the application, does the client send a SMB_COM_NT_CANCEL to cancel the outstanding request? 3) If it waits indefinitely, does it send more than one echo request? If so, how frequently are they sent? 4) Do more recent versions of Windows behave similarly? -- Jeff Layton <[email protected]> _______________________________________________ cifs-protocol mailing list [email protected] https://lists.samba.org/mailman/listinfo/cifs-protocol _______________________________________________ cifs-protocol mailing list [email protected] https://lists.samba.org/mailman/listinfo/cifs-protocol
