Angelo,
Thanks for the response, I tried the following and it does not retry if the
file is not missing -- it will retry the user (or anonymous if user not
specified) cannot connect:
$ wget --tries=0 --waitretry=30 ftp://jccann@jumanji//state/eds_on
--06:06:57-- ftp://jccann@jumanji//state/eds_on
=> `eds_on'
Resolving jumanji .. done.
Connecting to jumanji[192.168.254.48]:21... connected.

==> TYPE I ... done. ==> CWD /state ... done.
==> PORT ... done. ==> RETR eds_on ...
No such file `eds_on'.
(then wget exits)
$
I think perhaps the retry is a connection retry, not a file retry. The
'retry' option would be more convenient to retry if the file is missing. No
problem though, I wrote a simple shell script wrapper that will sleep for X
seconds if the file was not retrieved.
Thanks!
Jeff
