Transfer Protocol (SMTP) is working correctly.</p>

<p>If you detect a problem when using File Transfer Protocol (FTP), use the
|
||
|
|
following flow chart to identify the cause after using the flow chart for
|
||
|
|
general TCP/IP problems. The cause lists that follow list steps to help you

|
||
|
|
for a user id? If so, check the configuration of the domain name server on
|
||
|
|
your iSeries.
|
||
|
|
The FTP server performs a DNS query as soon as a new connection is received.
|
||
|
|
DNS problems can cause the server to hang for several minutes before a response
|
||
|
|
is received.</li>
|
||
|
|
<li>Check to see if an exit program has been added to the FTP Server Logon
|
||
|
|
Exit Point. If yes, then check if the logon that is unsuccessful is allowed
|
||
|
|
by the exit program.</li>
|
||
|
|
<li>Check to see if the remote logon requires a password if a password was
|
||
|
|
requested. Some systems request a password, but the connection can fail because
|
||
|
|
it is not required.</li>
|
||
|
|
<li>Set up a password on the remote system if required. You might need to
|
||
|
|
restart if you change the security information about the system.</li>
|
||
|
|
<li>Check your user ID and password by attempting to sign on to your remote
|
||
|
|
system. If you are unable to do so, contact the system owner to verify that
|
||
|
|
your user ID and password are correct.</li>

|

<li>Check to be sure the mapping tables on both the client and server systems
|

|
|
are compatible. You need only do this if you are using your own mapping tables.</li>
|
||
|
|
<li>Check to see that the correct CCSID has been specified for the transfer.
|
||
|
|
If not, use the TYPE or LTYPE subcommand to set the correct CCSID value before
|
||
|
|
the transfer is performed.</li>
|
||
|
|
<li>Create a file on the system that you are planning to store data into.
|

Set the proper record length, number of members, and number of increments.

Try the data transfer again and verify that it was successful.</li>
|

<li>Check to see if the FTP server timer ended. The iSeries server time-out value can be
|

|

set using the QUOTE TIME command.</li>
|

<li>Use the NETSTAT command to verify that the *LOOPBACK interface is active.

Then re-create the problem doing FTP LOOPBACK (iSeries-to-iSeries internally).<ul><li>If the problem cannot be recreated, it is probably a remote system problem.</li>

using the TRCTCPAPP command.</li>
|

<li>Create the problem again.</li>
|

|

|

<li>End the FTP server trace using the TRCTCPAPP command.</li>

<li>Find a spooled file with the following characteristics: <ul><li>The file name is QTMFFTRC</li>

<li>The username associated with the file is the name of the user who issued
|

the TRCTCPAPP command.</li>

<p>The trace is a spooled file in the default output queue of the system

associated with the FTP server job.</p>
|

</li>
|
||
|
|
<li>Send in that spooled file.</li>
|

|
|
<li>If the problem was on the iSeries FTP client, a trace can be obtained
|
||
|
|
using the DEBUG 100 client subcommand.</li>
|
||
|
|
<li>When running the FTP client interactively, use the F6 (Print) key to create
|
||
|
|
a spool file that contains a history of the FTP client subcommands entered,
|
||
|
|
and the associated FTP server replies. When the FTP client is run in batch
|
||
|
|
unattended mode, then this history of subcommands and server replies is written

to the specified OUTPUT file.</li>
