APAR Error Description / Circumvention
-------------------------------------------------
FTP server usually selects the same port in the port range for
data connections in passive mode.
CORRECTION FOR APAR 'SE68964' :
-------------------------------
After applying the fix, FTP server will randomly select the port
in the port range for data connections in passive mode.
CIRCUMVENTION FOR APAR 'SE68964' :
----------------------------------
None.
Activation Instructions
None.
Special Instructions
End FTP server in the system
Example: ENDTCPSVR SERVER(*FTP)
Then apply the PTF
Start FTP server again
Example: STRTCPSVR SERVER(*FTP)
********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************
SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI66917 :
=================================================
5770TC1 *BASE (IBM TCP/IP Connectivity Utilities for i) must be
installed in the system before applying this PTF.
SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI66203 :
=================================================
END FTP SERVER IN THE SYSTEM
EXAMPLE: ENDTCPSVR SERVER(*FTP)
THEN APPLY THE PTF
START FTP SERVER AGAIN
EXAMPLE: STRTCPSVR SERVER(*FTP)
"Please end the FTP server before apply the PTF:
- ENDTCPSVR SERVER(*FTP)
Start the FTP server after the PTF is applied:
- STRTCPSVR SERVER(*FTP)"
Please end the FTP server before apply the PTF:
- ENDTCPSVR SERVER(*FTP)
Start the FTP server after the PTF is applied:
- STRTCPSVR SERVER(*FTP)
Before applying/removing PTF:
endtcpsvr *FTP
After applying/removing PTF:
strtcpsvr *FTP
Example to enable the function to limit the job numbers:
endtcpsvr *FTP
ADDENVVAR ENVVAR(QIBM_FTP_MAX_CONC_CONN) VALUE(3) LEVEL(*SYS)
strtcpsvr *FTP
Note: the value should be greater than 0, if not, the function will not
be activated.
Before applying/removing PTF:
endtcpsvr *FTP
After applying/removing PTF:
strtcpsvr *FTP
Before applying/removing PTF:
endtcpsvr *FTP
After applying/removing PTF:
strtcpsvr *FTP
Example to enable changing return code:
endtcpsvr *FTP
ADDENVVAR ENVVAR(QIBM_FTP_CHG_RET_CODE) VALUE(1) LEVEL(*SYS)
strtcpsvr *FTP
Example to disable changing return code:
endtcpsvr *FTP
RMVENVVAR ENVVAR(QIBM_FTP_CHG_RET_CODE) LEVEL(*SYS)
strtcpsvr *FTP
Before applying PTF:
endtcpsvr *FTP
After applying PTF:
strtcpsvr *FTP
1. Before Applying/Removing the ptf:
ENDTCPSVR *FTP
2. Apply the ptf
3. set QIBM_FTP_SRV_TRUNCT_DLY to enable the new feature
ADDENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)
4. After Applying/Removing the ptf:
STRTCPSVR *FTP
Adding or removing the value(QIBM_FTP_SRV_TRUNCT_DLY ) while FTP is
running will have an FTP job change behavior on the next incoming
transaction.
FTP will take the change on the next transaction regardless of
the job if the server is restarted using ENDTCPSVR/STRTCPSVR
This new feature will change the "STOR" internal handle behavior
that FTP server will receive the new file to overwrite the existing
file, then it will truncate the receiving file.
Notes: This feature is recommended to enable for certain
scenarios. Example: The existing file is quite big and the size of
the sending file is similar with the existing one. Otherwise,
it is not recommended.
The example to enable the feature:
ENDTCPSVR *FTP
ADDENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)
STRTCPSVR *FTP
The example to disable the feature:
ENDTCPSVR *FTP
RMVENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)
STRTCPSVR *FTP
1. Before Applying/Removing the ptf:
ENDTCPSVR *FTP
2. Apply the ptf
3. set ENV variable to enable the feature
ADDENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)
4. After Applying/Removing the ptf:
STRTCPSVR *FTP
Adding or removing the value(QIBM_FTP_PORT_EPRT_LIMIT) while FTP is
running will have an FTP job
change behavior on the next incoming transaction.
FTP will take the change on the next transaction regardless of
the job if the server is restarted using ENDTCPSVR/STRTCPSVR
example to enable the feature:
ENDTCPSVR *FTP
ADDENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)
STRTCPSVR *FTP
example to disable the feature:
ENDTCPSVR *FTP
RMVENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)
STRTCPSVR *FTP
Before Applying/Removing:
ENDTCPSVR *FTP
After Applying/Removing:
STRTCPSVR *FTP
Note: any change to an exit program requires a server restart
regardless if this PTF is installed or not.
Before Applying/Removing the ptf:
ENDTCPSVR *FTP
After Applying/Removing the ptf:
STRTCPSVR *FTP
Note: This fix relies on message TCP12E2 in message file
QTCP/QTCPMSGF
to be unaltered. If for some reason the message has been altered
it
needs to be restored before this fix will work. The most common
problem is adding a dash after the 250, this message is not shipped
with a dash.
The FTP server must be restarted before this PTF will take affect in
immediate mode.
Before Installing/Removing
endtcpsvr *ftp
After Installing/Removing
strtcpsvr *ftp
The FTP server must be restarted in order for this fix to be activated,
and the FTP and FTP-SECURE sockets need to be closed.
Before Installing/Removing the PTF:
endtcpsvr *FTP.
check netstat option 3 and option 6 to see if there is a an ftp
listening socket.
install all ptfs for ENDTCPCNN.
Use ENDTCPCNN or option 4 from netstat to end the socket.
If there isn't a socket to end then this ptf is for prevention only.
After Installing/Removing the PTF:
startcpsvr *FTP.
Before Applying/Removing
endtcpsvr *ftp
After Applying/Removing
strtcpsvr *ftp
If you do not wish to take advantage of this change,
nothing needs to be done.
If you wish to take advantage of this change:
Add a client application ID to the Digital Certificate Manager (DCM).
Specify the created Application identifier (APPID) parameter on the
Start TCP/IP File Transfer Protocol (STRTCPFTP) or
Start TCP/IP File Transfer (FTP) command when using SSL.
Default Instructions
THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
