FTP not accessible from outside of our network
 
This is my first posting on this site and I'm hoping that someone can assist me with a nagging issue that has plagued me for the past week. We have an FTP server running Suse and it had been working just fine until recently. Now, I am still able to access the FTP folders from our network but those outside of our network are not able to access them. They consistently receive the error: Windows cannot access the folder make sure you typed the filename correctly and have permission to access the folder. Details: connection with the server reset.

We are trying to access the folder through a window as opposed to using a browser. It appears to connect and search for the files but denies access each time. I've checked the permissions and the firewall settings but can't seem to get it to work. We've also put it outside of our firewall so we're pretty sure that its a problem with the settings on the computer.

My experience with Linux is quite limited so your help is greatly appreciated.

well you need to get windows out of the equation for a start, what happens with a command line ftp connection? what does it say on the ftp server logs? what if you run "tcpdump port 21 -n" on the server and then try to connect? is there a software firewall on the box?

FTP issue
 
thanks for the advice, unfortunately, I'm not sure how to do those things in Linux. can you give me step by step directions how connect via command line, check the server logs, and run tcpdump port 21 -n? yes, there is a software firewall. i'm quite unfamiliar with linux so please forgive my ignorance.
