Hi All,
I am one of those people having issues getting ftp to work right but I think I have a different twist to it. First off I will give you some back ground. We use FTP over IIS 7 to automate some file transfers at night. Right now this is working fine for about 10 client systems. These client systems are spread scross the globe and are all running Server 2008. These clients are all either systems we own or are hosted at co locations. The clients use windows firewall (the hosting company set them up this way). The server also uses widows firewall but also sits behind a Cisco ASA 5505. All of these clients are working.
Recently it was decided that we willstart moving servers up to AWS (Amazon Web Services). We started by moving a test system up there to make sure everything works and all issues can be resolved when we start moving the rest of the systems there. So far everything but one critical service is working fine... our process of using FTP to move some files from this client to the server. This new client runs Server 2012 and is not a physical machines but an AWS instance (as mentioned just a bit ago). When connecting form this client to the FTP server, we can change directories and see where we are using pwd and even create new directories so we know the control port is up. However nothing else will work, 'dir', 'get', 'put', they all stall out. I have been on just about eveyr forum I could find to try and figure out the problem. I have opened all the ports in all the right directions. I have even removed all blocks and turned off all firewalls, except for the ASA, I am not allowed to put the ftp server in front of it, but that is also a moot point as the ASA is configured to allow all traffic in and out, since we use windows firewall to allow and block spcific traffic. Even with all this, the problem persists. I am justabout at my wits end as this is not making ay sense to me having removed what I thought were all places that could be blocking access. Is there anything I may be overlooking in this situation, regardless of how small it may seem?
