I have one site that gives me trouble downloading anything more than 120k!
However I can download the entire Fedora Core distribution from other
sites (inc the DVD) just fine. I have never had any problems downlaoding
anything from anywhere ...
Now if I check the MTU size with "ipconfig -a xxxx" I get
inet addr:xxxxxxxxxxxxxx Bcast:xxxxxxxxxxxxxxx Mask:xxxxxxxxxxxxxx
inet6 addr: xxxxxxxxxxxxxxxxxxxxxxxxxxx Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:10675429 errors:25 dropped:0 overruns:0 frame:50
TX packets:9778109 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:3951229718 (3768.1 Mb) TX bytes:2449740474 (2336.2 Mb)
This is a standard MTU size, right?
Now I have been talking to one of the techies @ my ISP (internode)
and he suggested to drop the MTU size down to 1000.
Telnetting into the other server (the one I have problems with):
GET / HTTP1.0
HTTP/1.1 302 Found
Date: Thu, 01 Dec 2005 13:14:02 GMT
Server: Apache/2.0.46 (Red Hat)
Ahh! That is a Linux box (I assume its RedHat 3).
So why do I have problems downloading from THAT (and only that) one???
What would be an optimum MTU size?
Does the ADSL modem (which sits infront of that ethernet card) have
some influence in the entire story???
File not found! Do you want me to fake it?
