Hi
3 people in the last 24 hours have had to set to use passive mode in the connections setup…
the symptoms are:
the file to upload gets “stuck” …ie the ftpupd.exe tries to upload the file but just sits there until it times out, and then there is a error of some description in the view, ftp log, view full log
Simply to, under setup, control panel, ftp/internet setup, connections, use passive mode

Those who use a regular FTP Client typically have a ‘global setting’ where it (passive mode) can be set to default to ‘on’. Makes things much easier.
Can someone explain passive mode for me?
I’m on satellite and tried passive mode when my uploads were timing out - seemed to help some.
I just got hooked up with cable
active
The main problem with active mode FTP actually falls on the client side. The FTP client doesn't make the actual connection to the data port of the server--it simply tells the server what port it is listening on and the server connects back to the specified port on the client. From the client side firewall this appears to be an outside system initiating a connection to an internal client--something that is usually blocked.
passive
In passive mode FTP the client initiates both connections to the server, solving the problem of firewalls filtering the incoming data port connection to the client from the server.
XP SP2 shuts down some ports by default, that may have a bearing on this too.
so maybe i should have this on by default?
I’m not sure if it’s available by default on all servers, so it might not make things any better?
I don’t recall that we have had an ftp issue on here that was solved by switching to “active” IMHO defaulting to passive would be a good bet.
Perhaps not. But the default active setting seems to work for many people and where it doesn’t work there’s a good chance that passive mode will work. However, that’s not to say that if all active mode users switched to passive mode they’d find it worked without problems!
Although having said what I just have, I’ve switched my connection to PASV mode and it’s working fine.
I’m not suggesting re-setting existing users to active. If Brian sets it as the default wouldn’t that only affect new users, not updates of existing installs that would get the setting from ini or reg?
This is borrowed from the WS_FTP help file.
[quote]Passive Transfers (definition)
Normally, when you connect to an FTP site, the site establishes the data connection to your PC (the client). However, if the site allows passive transfers, you can have your PC establish the data connection.
We recommend that you use passive mode for most transfers. Note that passive mode may be required for users who are behind some types of router-based firewalls or behind a gateway requiring passive transfers.
