IBM - Disabling EPASV/EPORT in the iSeries FTP Client at R610 and above

Technote
At R610, the iSeries FTP client supports the EPASV (Extended Passive,
EPSV) command and EPORT (Extended Port, EPRT). The FTP client
defaults to this and, if the server we are connecting to does not, the FTP
client will fail over to Passive mode FTP. However, in some cases, an error
message is not returned. Most commonly, this is due to a firewall not
allowing or supporting the EPASV /EPORT command, and the establishment
of a data connection will appear to 'hang' with:
229 Entering Extended Passive Mode
In these cases, the EPASV/EPORT commands must be disabled.
The FTP client attempts data connections in the following manner:
Extended Passive
Passive
Extended Port
Port
As a result, if PORT mode is needed, the three preceding data connection
types must first be toggled off. This can be done in one of two ways:
1. On a connection-by-connection basis using FTP client subcommands:
o SENDEPSV - Toggles Extended passive
o SENDPASV - Toggles Passive mode
o SENDEPRT - Toggles Extended Port
Note: The data connection type can also be set (regardless of what the
default behavior is) by using the 0 or 1 switches with the above 3
commands. For instance:
SENDEPSV 1 - would toggle extended passive on
SENDEPSV 0 - would toggle extended passive off
2. On a system-wide basis with the use of data areas:
o CRTDTAARA DTAARA(QUSRSYS/QTMFTPEPSV) TYPE(*LGL)
AUT(*USE) - disables EPASV
o CRTDTAARA DTAARA(QUSRSYS/QTMFTPPASV) TYPE(*LGL)
AUT(*USE) - disables PASV
o CRTDTAARA DTAARA(QUSRSYS/QTMFTPEPRT) TYPE(*LGL)
AUT(*USE) - disables EPO RT with PTF SI33243 applied to the

Well that's good...but it doesn't make sense unless we're talking about a
different problem than the one i assumed. PASV or EPSV set up the data
connection (EPSV is really just the ipv6 version of pasv). Once the data
connection is in place it doesn't matter which one was used. If the problem
was in establishing a data connection for a transfer then I can see how
perhaps the firewall had an issue but after that...
But hey, if it's working...

The EPSV has problems with firewalls

If the timeout is happening after it has been sending for a while then
I don't see any reason why a switch from EPSV to PASV would have any
effect whatsoever.
But, I had discovered in another post about using passive mode (PASV)
......as opposed to the default of ... extended passive mode (EPSV)
That seems to do the trick
....it does not have issues with the firewall now ....no time out
