Trouble uploading files to internet

[swatsbiz]

I seem to be having trouble uploading files to the internet, mainly with ftp, although it seems to apply to http website file uploading too.

I have tried a number of solutions to this from filezilla, fireftp (add-on to firefox), and even dreamweaver through wine, but with similar results. I can connect to the server, and upload one maybe two files, but after that the connection times out and I it seems to refuse to upload any more files. With fireftp and filezilla it'll reconnect after the timeout, but not upload the file >

Any suggestions about where to look or what to do, any logs I can provide?

That's seems to be a network problem, or less probable the server itself is applying kind of policy.
If the application itself (ftp) does not provide logs, system could report something at /var/log/messages

Anyway, you can check somethings. Do you know which is your NIC name? mine is eth0. So

ifconfig eth0

eth0 Link encap:Ethernet HWaddr xxxxxxx
inet addr.x.x.x Bcast.x.x.x Mask.x.x.x
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:3032302 errors:0 dropped:0 overruns:0 frame:0
TX packets:2642492 errors:0 dropped:0 overruns:0 carrier:0
collisions:17878 txqueuelen:1000
RX bytes:3420046398 (3.1 GB) TX bytes:1384413639 (1.2 GB)
Interrupt:5 Base address:0xe000

When your connections is on, repeat the command above. Does it constantly increase any of the bold numbers above? That would point to a physical problem on your computer (cable, modem, NIC, whatever...)

You may check the network stats too

netstat -s -t

this is a long output, you may study it a bit. Pay attention to
366 failed connection attempts
135 connection resets received
56205 segments retransmitted
352 bad segments received.
772 resets sent

Increasing them constantly may indicate MTU problem in your path to the server. This is hard to verify specially because this debug information is discarted in order to prime for security, so I believe the command bellow will not work for you

tracepath [url]www.<your[/url] server>.com

Anyway you may try it.
Good luck.

PS: after checking, a good advice would be opening a ticket at your ISP if this is the case

Thanks for your reply.

I would like to point out that I have no problem using ftp while booted into windows, which suggests to me that it is a configuration setting somewhere. I've considered whether my router is getting in the way somehow ... but not sure why.

here is the output from those commands:

ifconfig ath0

ath0 Link encap:Ethernet HWaddr xxxxxxx
inet addrx.xx.xx.xx Bcastx.xx.xx.xx Maskx.xx.xx.xx
inet6 addrxxx:xxxxxxxxxxx/xx Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:92943 errors:0 dropped:0 overruns:0 frame:0
TX packets:74137 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:96186240 (91.7 MB) TX bytes:12932717 (12.3 MB)

The "0"'s did not change
