Re: FTP time-outs

Alan

There is a little-known server sub-command that can be used to set time-outs

TIME <inactivity> <transfer>: Sets server time-out values for this FTP session.

<transfer> is optional

This is run using the QUOTE client sub-command

So from your client you can run

quote time 900 30

sets inactivity timeout to 15 minutes and waiting for data to arrive to 30 seconds - at least I think that is its meaning.

Run STAT from your FTP session to see what the values are for your session now. One of our machines comes back with

211-File transfer time-out value set to 420 seconds.
211 Current inactivity time-out value set to 3600 seconds.

when using ftp to loopback.

Inactivity timeout is settable with the CHGFTPA command - transfer timeout is not. The inactivity timeout is also the source for the message you get from an iSeries when you first enter an FTP session - Connection will not be closed... ' or 'Connection will close if idle...'

This might have no effect on a Windows FTP server or a Linux one.

Morning everyone
I have a question concerning ftp. Hopefully my question comes across the
way I want it to.
We have a script that gets files via ftp from different sites. If for some
reason that ftp site is not available, we have to wait for a time-out to
occur on the ftp request.
Who controls that time-out? Is there a way to programmatically recognize
that situation to circumvent the time-out?
Here is a copy of what the FTPLOG looks like
6/03/08 22:08:30 XXXXXXXX Send FTP File (SNDFTPF) Command Log
Input read from specified override file.
Connecting to remote host 123.45.678.901 using port 21.
Cannot connect to host 123.45.678.901 at address123.45.678.901. Try again
later.
Enter an FTP subcommand.
etc
etc

As usual, many thanks for any and all help offered
