RE: Windows XP and FTP

Why not just use IE's built-in ftp capabilities?  You can set it to passive
mode by going to Tools > Options > Advanced and ticking off "Use Passive
FTP".  Then it's just a simple matter of typing in ftp://ftp.host.com in the
address bar and supplying your credentials.

Thanks so much Nick,

This is too what I thought - however I was hoping for a work around, or
patch to fix this issue - it is going to be hard to explain to every
client
I have using XP that they will have to disable their firewalls - hopefully
someone can shed some light on this issue for both of us.



Kindest of regards,

I have Windows XP (as do many of my clients) and have noticed

Windows (XP Pro) Firewall is turned on, you cannot perform this task.
Sometimes it has problems resolving the hostname, sometimes it just
doesn't connect at all. When disabling Windows Firewall FTP works
fine, however when just enabling FTP Access via the firewall
configuration it doesn't seem to want to work. My XP using clients
seem to be having the same problem.


Looks like you (and your clients) are using FTP in active mode. In that
case the FTP server tries to establish the data connection to the client
which is then intercepted by the Windows Firewall. Try using passive
mode.

If you use the commandline FTP client: ftp.exe from Windows does only
support active mode IIRC, so use something like ncftp [1] instead.

I just dealt with a user who was unable to connect with XP and FTPX, but
if
they used the command line, it worked just fine. PASV mode didn't seem to
make any difference. It's almost like the XP firewall doesn't keep ftp
states. I use an iptables firewall to connect to the server (proftpd) and
have 0 problems. When I had the user disable the windows firewall, it
connected immediately. It's a recent problem, I have a feeling that MS
changed the behaviour of the firewall recently, perhaps inadvertantly?

I recommended that the user try another firewall, but this seems like an
MS problem...
