I'm at work; I can see my FTP at home and login, but no folder list...get timeouted...WTH? Why?

[MichaelD]

I don't get it. My FTP at home is up and running. I can connect to it. I get the login dialogue box. (No anonymous logins allowed though...disabled that)

I can login is any of the current users, including Admin that I already have. But when it goes scanning for folders (the little scanning flashlight icon) it just goes and goes and after about 5 minutes or so, it times out>>>>WTH?

My connection isn't THAT slow. My GF gets 15kb/s, and she's on a different ISP than I.

I am thinking that possibly inbound FTP traffic is blocked (remember, I'm at work) but if that was so, how would I be able to login? Port 21 is port 21, right?

You need to set your ftp client to passive mode

 

[LordThing]

Are you using a proxy/firewall at either location? If so, you might want to turn on passive FTP to allow for the connection.

May be grabbing at straws here...

They probably have the port(s) restricted.

You need both 20 and 21 for FTP.

First off, are you using IE to connect? If so, I would suggest getting a real FTP client like WS_FTP. It will display real error messages which will help. The only thing I can think of now is to try active mode instead of passive (or vice versa).

 

[MichaelD]

Firewall? Oh yeah. At work we have prolly one of the tightest firewalls money can buy...that's prolly it.

I have a router serving as my firewall at home, but port 21 is forwarded to my server. Everything else is blocked.

My GF CAN login/download so it's prolly the firewall here at work.

Thanks guys.

Its odd though that you are able to authenticate and not able to make a full connection. As someone else asked above, what FTP client are you using? Any error messages? I wanna get this working for ya bud. Going to do some research.

That's what it sounds like to me too.

It appears they are allowing port 21, which is the command port and explains why you can log in.

However they are blocking port 20 which is the data port when using Active FTP.

As Czar mentioned, you could try Passive FTP which uses a random port for data rather than port 20 and it might work, it depends on how the firewall is setup.

One other thing to ask is can you FTP to anything from work, like ftp.microsoft.com?

Asked the router guy, and Gregg (Viper) is right. Probably your local firewall is blocking port 20. When you make a connection to an FTP you authenticate accross port 21 and the server makes a connection back to you on port 20. If you set up your client to work in passive mode, the data should be passed back to you across port 21. SHOULD.

Hope it helps

Edit: well, wanna clarify. Not you as in your router config is wrong...You as in your work Firewall is not allowing it. Don't want you to think its your fault.

Thanks, Lord Thing. I appreciate your time. It's gotta be my work b/c someone here at AT just logged in and DL'd stuff from their home. At home, my router forwards port 21 to my server's internal IP. I'll try out the passive mode and see if I can get stuff at work. That'd would be neat as it's one of the original reasons I built a FTP server in the first place.

ps
I'm using GuildFTP. It's free...works for me.

pps
I CAN see and DL from ftp://microsoft.com
