Is Bob's crafty FTP site down?

Post by Dave K »

I have been trying for at least two weeks to get in using IE, Mozilla, and two standard FTP clients. In all cases the connection times out. DNS is finding it but that's all.

It works fine for me. Try ftp://ftp.cis.uab.edu/pub/hyatt/

That's what I'm using. I have shut down my internal software firewall, and verified the firewall in my router is allowing ports 20 and 21.

It is working as far as I can tell. Just checked. I had, within the past week, copied my new starting positions for cluster-testing over there as well and they have been downloaded a few times recently.

Just for the heck of it, I turned off passive mode in IE and it worked. Now to find out where I set that option in Mozilla and the FTP clients.

Passive mode should work. We have to use that here since we have a firewall. You do need to both turn it on in your ftp client and also make sure your client tells the remote end (us) to use passive mode, else our ftp daemon will promptly try to open a new connection back to you that will not make it past your firewall and time out...

It appears the outside firewall may be blocking passive requests become it looks like the software firewall is configured to allow them.

The question is, how? Passive requests go over the same channel as the control information, which you have to use to log in in the first place. There is no new connection in passive transfers to avoid just this problem....

I'm at loss Bob. I know I have had access your site since I installed this router/firewall/modem but I turned it off and everything works fine in PASV mode. I could find no hint of it differentiating between active and passive. The only recent change has been switching from ZoneAlarm to the Comodo firewall which is configured for both modes. This is probably the first time I have tried to reach your site since then, so I surmise there's some kind of issue between the two. It's not the first time I have found and issue with this router which is an Actiontec M1000.
