Hello everyone. I'm hoping to make contact with someone who has seen this issue before.
I'm trying to set up probably the simplest web site you've ever seen. It is one page, populated with a few charts and graphs and some text. This is my first, and I did want to keep it simple.
I have a weather station that continuously gathers data parameters, temperature, humidity, rain, wind, etc... and wirelessly transmits to a receiver that feeds it to the computer. There, a program automates charts, graphs, data storage, etc... and feeds data to Weather Underground and Citizen's Weather Observer Program (CWOP) on the net. (Links below) It also will generate a simple web page for me to upload to a web site. In full automation, it will generate a new page with new chart data every 15 minutes and upload it via FTP.
Here's where the problem starts. I can't get FTP to work from this location. Symptomatically, using FileZilla or any other FTP client program, I can successfully log in to the server, list directories, change directories, and even upload small HTML files of ~500 bytes or less. However, 1,500 bytes or larger (that's the next size up in the collection of parts for this web page), and it appears as though the client application sends the complete file and waits, only to time out. The remote directory is populated only by the file name of the sent file containing 0 bytes.
The Unix server is using passive mode, simple FTP. The support staff is worthless.
I had someone else in another location log in as me, and they were able to upload successfully.
I am using a router on a LAN, but in troubleshooting the problem, I have bypassed the router and connected directly to the WAN at the DSL modem. Same problem. Same symptoms.
I really don't think it has anything to do with the issue, but in the interest of full disclosure I'm running the latest iMac with OS X Lion Version 10.7.4 and I've tried it on on 3 separate computers and 2 hosting services without success. The friend who was able to upload to the account is in a different city with a different ISP running Windows 7. Every other network job that has involved uploading services, such as SmugMug, etc... has worked without fail. This one just baffles me.
Anyone got any idea on this one? I did call the ISP and got the standard "everything looks OK here" treatment. They offered to sign me up for a very expensive technical support plan.
