Remember! We do not allow connections from ".net" domains at this time. If you are coming from a non-".net" domain, read on for the most common problem.
Some users/sites can not access our FTP server because the originator's site is not doing things properly, or what we consider proper.
We do simple DNS authentication for all users accessing our FTP site, we've done this for several years because of previous abuses. Thus, we require all anonymous users to have their machines registered such that a check of the originating system's IP number "18.104.22.168" resolves to a DNS name. Those sites that do not do this basic DNS courtesy are considered potentially dangerous. This simple technique has served us well.
To check if you are setup properly do the following from any UNIX based system.
This isn't a guarantee that you should have access, but it is a positive indicator. We have seen some sites configure their DNS server to work locally but not globally.
If you need help with how to configure your DNS systems, send us the following information ...
- Your DNS Server [optional, helpful]
- The system you are attempting to FTP from
- with the system's host name
- and the system's IP number
We expect your local DNS administrator to know how to resolve your problem. But we can point out if the DNS resolution is working and why it fails. A quick work-around? Find a machine that does DNS resolve properly.
Your administrator, at a minimum, should be able to direct you to a machine that can accomplish the FTP. If you are sitting behind a firewall or something see your administrator we can't help you.
Otherwise, if you fail to get a DNS administrator to assist you recontact us and we will ask if someone is willing to vouch for you to make special accomodations. If you don't know anyone, we will be slow to respond as we strongly encourage the correct procedure illustrated above (its the courteous way of doing things.)
