Still connected but remote window blank.

Hello,

My remote connection window goes blank intermittnely but usually pretty soon after connecting to my server. I am using FlashFXP at the request of my host after a disaster with WSFTP_Pro where it would open hundreds of connections and die repeatedly during transfer or idle.

But the same problem is happening with FlashFXP except that it only opens about 50 connections according to my host. What happens is my remote connection window goes blank and FXP hangs. I have read many posts in the last 2 hours and done some work to figure this out but am still at a loss.

Here goes.

FlashFXP Version 2.1 (Build 924)
Windows XP Home
Zone Alarm 3.7.211
TrueVector 3.7.211
Driver Version 3.7.211
Host FTP server: ProFTPD 1.2.8

Log of last connect.

The last line is not a disconnect but is when the remote server display goes blank and I am unable so view the files or refresh to view them. The middle display says their are 0 Folders, 0 files. I installed Active ports to watch all my ports and it seems that data being sent back from the server was being blocked. I then checked my firewall and that IP was blocked so I allowed it and attempted again. Active ports still shows the server IP and port as blocked even though firwall doesn't. Next step was to shut off firewall and attempt connections. I have added the sending of the NOOP command to keep connection alive but it too fails to resolve the problme. My web host is using earlier verion of FXP without firewall and not experiencing any of the same troubles that I am. But I have the same result everytime; which is the log above.

It seems that the connections back from the server are being blocked and that the server keeps sending them because the connection was never properly closed. Thus when I reopen FTP app it creates new connections to server and problems start all over with many connections being added and not closed. This increases server load sky high. Needless to say my host isn't very happy and neither am I. I am getting frustrated.

Thanks,

Kris

when you get empty dir list, go to "Directory" menu, "View Raw Directory".
do you see anything there?

also as a troubleshooting step, try to completly uninstall ZA. disabling it sometimes isn't enough. make sure it's uninstalled, it's services are gone and TrueVector is gone too.
once that is done, try to use FlashFXP and see if that makes any difference. if so then it's ZA to blame..
do you have any type of routers on your connection?

also what's your Antivirus software?

Sorry it has taken me this long to get back with a reply I had to go to work where I am right now and can't answer in full about the type or version of Anti-virus software I am running. I am beginning to think it may be the anti-virus software because I have duplicated my problem here at work and the Virus software brand is the same. I contacted another guy here at work to ask him if he could help and he says that he has been having similar problems here at work and at home witih FTP. No specific client just every one that he uses.

What I am running here at work is Virus Scan 7.0, Virus definitions 4298, Scan Engine 4.2.60 from October 15, 2003. I may be way off base with this Virus Scan thing but it is the only thing that is the same for me at work and at home.

I don't know what firewall is running here but I am sure it is much better than my Zone Alarm since we have about 10,000 employees and an IT department.

I do not have a router set up. I have a cable connection through an external Surfboard Modem that I can get more specific on later tonight when I get home.

Thank you MxxCon for responding anyone that can help me figure this one out and get me back into business can have some goodies from my sites http://www.thebeershirtguy.com and http://www.buckssupply.com/store.

This is a big deal for me because my web host will won't allow me to test or use my FTP unless I am online messaging them while doing so they they can monitor and I need to get this going.
