I have a very odd problem connecting to some websites from my CentOS 5 box
Target websites:
www.connecttech.com
www.3ware.com
(two of my HW vendors)
I can usually get some kind of response, but if the content (download
or page itself) is larger in size (downloads never pass 100K), then it
hangs...
I had an odd issue with an FC6 laptop on a hotel wireless network where
any encrypted traffic (ssh, https) would hang after a certain amount.
The fix was to turn off TCP window scaling
(echo 0 > /proc/sys/net/ipv4/tcp_window_scaling). Some googling revealed
that some routers have issues with TCP window scaling - I don't know why
it only affected encrypted traffic in my case, but the fix may be worth a
shot for you.
