You should be able to wrap the problematic method call with an "eval"
and have a look at $@ afterwards.

And according to the Net::SFTP perldoc there ist the status() method to
find out if something nasty happened after you called any of the other
methods except from new().

I could give that a shot, but it appears that there isn't one
particular "problematic" method call. It's just when the remote server
disconnects me, the entire script goes ends with an error. It could be
right in the middle of a file transfer. It I wrapped the entire thing
in an eval block, it would be a bit of a pain to try and figure out
where in my nested loop I was when the connection dropped and would
most likely have to just start the entire process over again.<br>
<br>
Which is sort of what I've resorted to doing, I was just hoping there
was a way to have Net::SFTP tell me when it dropped connection as
opposed to just "dying".<br>

    <pre wrap="">And secondly, the less important issue... my clients server doesn't 
allow me to fsetstat which doesn't appear to be a problem at all, but 
the script is outputting a large number of "Couldn't fsetstat: Operation 
unsupported" messages. I'd like to disable only that message if possible 
as it's not entirely useful while other error messages &amp; warnings are.

As far as I know, you cannot disable one specific warning - but you can
pass a sub ref as argument "warn" to the new() method in which you can
then decide what to do with the warnings you receive. See the perldoc
for more info</pre>

Do you know if there is a simple way to prevent attempting to perform
fsetstat on a put?<br>

Thanks again .. <br>
