Binary mode ftp transfer is extremely slow

I have setup networking via a 100M ethernet hub between my Sparc Ultra-5 and nt laptop. All communications seem pretty fast, i.e I can access a html port on the sun server from the nt laptop and it loads up the pages extremely fast !

The problem is ftp ......... when I try to ftp between platforms the speed is down to 0.01K /ps ????

I have tried all conventional hme operational parameters to fix , half duplex full duplex different rates 10 /100M.

No luck !

Any Ideas ?

Cheers

That sounds like an autonegotiation failure between the systems and the hub. A good place to start is to check the hub docs and see what it supports and how it behaves. You may need to set both systems in the event of an autonegotiation problem. Tell me what hub you've got (make/model) and I'll try to look it up.

Off hand my guess would be that you either need 10Mbps/half or 100Mbps/half if it's not one of the more sophisticated 10/100 hubs supports split speeds. The low end hubs drop everything to 10/half if there's one 10Mbps device connected and won't do better than 100/half otherwise.

I can pull data from the sun to the nt platform with no problem(extremely fast) however ,

 ........... Pushing data onto the sun from the laptop or pulling from the sun results in the poor performance !

The hub is a Office connect ethernet hub 4 from 3com

Thanks

Okay, but which OfficeConnect 4 port hub, the Ethernet (model 3C16704A) or the FastEthernet (model 3C16723A)?
just a thought: check network settings, ie subnet mask and routing on the laptop.
Can you post  iptrace taken during file transfer ?
I fixed the problem by getting a new ethernet card on the nt box.

Thanks,
