Connecting works fine on desktop, but not laptop.

Hi everyone,

"Can't establish connection --> 205.250.210.75:21 @ Mon Oct 02 00:20:41 2006 (0-5)"

This is the message I get when trying to connect to my home server as anonymous.

I can connect perfectly to my home server using CoreFTP, Mozilla and IE from my desktop and others' computers, but NOT from my laptop. My laptop can't connect at all!

I made all the settings the same
COREftp is allowed in firewall
active/passive makes no difference
info is correct.
Using (well.. stealing) my neighbor's wireless open access point
I can connect to other usual FTP, but not my own home server

Any ideas?

Thank you...

First idea:

You have an annoying Firewall on your computer blocking certain forms of connections.

Norton Internet Security, McAfee, Norton Firewall, ezTrust, eTrust, and ZoneAlarm Pro are all possibilities... Try disabling them temporarily and then connecting. If it works, you know where your problem is. If it doesn't, what Firewall are you using?

Are you connecting via wireless with your laptop and wired with the desktop?

Thank for the responses!

I've tried CoreFTP with AND without firewall, including windows firewall (which I don't use anyways.. stays OFF)

Desktop is DSL landline connection; Laptop is wireless, but plugging into landline doesn't work either.

My server administrator program has all the correct settings to allow anonymous access.

I think that your idea about my firewall not accepting specific connections might be the answer. Maybe I have to specify on my firewall who to allow IN and on which ports?

I will try to tinker with the firewall's advanced settings.

More ideas welcome!

Which Firewall software are you using?

Sygate personal firewall (free)

Also, in Sygate's Advanced Rules option, I made sure to allow the FTP clients, and I allowed anonymous access through port 20-21.

Another note: it turns out that my laptop AND other desktops cannot access my server. I previously thought it was just my laptop. I was wrong. Here is the new message:

"an established connection is being forcibly rejected by the remote host"

My server is rejecting connections. Why is it that my desktop computer, the one that administrates the server, can connect to the server?

sigh

Oh...that's quite a bit different.

What FTP server software are you using? If a computer is administrating, well...itself, it can make a loopback, it doesn't actually go through the network to connect to itself. It sounds like you have a setting issue on the computer that is the server...either with the Firewall (on that computer, to allow incoming data), the router, or with the FTP application itself.
