Please help me test my ftp server

[blackrain]

I am trying to set up an ftp server to share stuff with friends and family.

host address: 75.118.152.206

login: Test
pass: Test

port 53220


I am able to log in okay remotely from my laptop via wireless Internet card.

However, 2 people can't seem to log in. They get through the authentication okay (login and password seem to be accepted), but they can't get into the final listing of directories.
I thought maybe the problem was a firewall on their pc, but not sure.

Can you try to log on and let me know if you can get in okay or not? (and/or help me trouble shoot the problem my friends are having?)

This is normal symptom with running FTP on a non-standard port. The control channel works (logging in, sending commands) but the data channel (directory listing, sending data) which is selected by the server gets blocked by either a firewall or NAT on the server or client end. google "ftp nat control channel" and you should get some good information.

So does that mean that if I change the port to 21, I shouldn't have a problem?

Let me clarify one thing.

It works completely for me. I am able to log on remotely from my laptop without any problem. Hence, I thought that the problem might be client-side firewalls. That is why I am asking for others to try and log on so that I can see if anyone else is also able to connect okay.

Also, would changing to port 21 (or port 20?) help?

It would be a nice if someone could help me trouble shoot rather than just giving me theory. I understand some of the theory, but not all of it. And the practical solution may not be as easily recognizable.


Perhaps my setting would be helpful?

Hardware:

I have a Linksys WRT54G and have configured as follows:

Applications and Gaming>Port Range Forward:
FTP
Start (52000)
End (54000)
Protocol (Both)
IP Address 192.xxx.xx.xx

There is also a Port Triggering tab. I have left that alone (nothing is filled in). It lists a Triggered Range (Start and End Port) and a Forwarded Range (Start and End Port).


DMZ tab/option is disabled

QOS tab/option is disabled


Software:

Bulletproof Server
Settings:
Connection> Listen on port number 53220
Dynamic IP> Enable IP changes monitor and 192.xx.xx.xx has been added
Multi IP Settings> Passive Mode IP lists my actual IP and passive port range is 50000 to 50100

I wish I could offer more assistance. I can log in, but can't see any directories.

I rarely do anything using FTP. And since moving to Vista, I've had to go with new software that I haven't figured out by any means.

 

[blackrain]

I don't know if this is right, but I also added a port forward for 50000 to 50100

 

[blackrain]

So I basically followed these steps.

The only thing I really had to change was to add 50000 to 50100 to the router forwarding settings

port range: 50000 to 50100
TCP
192.168.xx.xx (internal IP address)


Now I need someone to help me test. Please?

Client-side firewalls can definitely interfere with FTP (with either standard or non-standard ports). Corporate-level firewalls will definitely have a problem with it and will require a special setup. I imagine that the more complex home-level firewalls could also interfere.

P.S.
It's not clear at all what Port you are running your FTP site on now. Is this still the address:
ftp://75.118.152.206:53220 ?

 

[blackrain]

Can someone help me test my ftp server step-by-step?

Yes, the port is still 53220

PS If you tried to connect last night, there was an electrical outage from a storm and and the server was down as a result. Its now back up.

I see the folder now (which is empty). But I temporarily opened up my Server's firewall last week to allow all outgoing traffic on all ports. Normally, this wouldn't work.

 

[JackMDS]

In other words when you use none standard ports some clients would have problem Not because of your settings but because of their settings.

However their many free simple servers that can let you use http download too, http://www.rejetto.com/hfs/

make sure passive mode is enabled on both the ftp server and the ftp clients

 

[blackrain]

Would changing the port number to 21 help?

Should I forward the port range 20-21 on my router (instead of 52000 to 54000) and change the settings on my server to listen on port 21?

It sounds to me like the problem might be a client-side router firewall issue.

Does everyone pretty much confirm that I have things correctly configured at my end?

Will changing to port 21 ensure that client-side router firewall will not be a problem?

How would you normally do that on a router (allow all outgoing traffic on all ports)?

I don't see that option on my Linksys WRT54G

I had the same problem one time when I installed a firewall.. I could access it fine inside my LAN but outside I would be able to login but get no file directory. I noticed that if you turn the FTP client off of Passive mode it would work fine, but a browser will not do this. I found out my firewall had the ability to turn on a FTP Helper, but I doubt a linksys one would. I am sure that if I messed with the port forwarding and Firewall settings more I would have been able to figure it out, try looking at the passive ports on the server's settings

I am not sure what else I can do. I followed the instructions at these links:
