ProLiant ML115 Fedora 8 Internet Connection Slow

[tameboy]

Hi

I am having problems connecting to the internet on my server. I have installed the Fedora 8 OS successfully, along with a http server which is very effectively serving my local intranet, but when I try to connect to the internet from the server, the connection times are prohibitively slow (8kbs on an 8Mb connection).

A lot of guys have given hints regarding possible solutions in the Fedora forum but no answer has solved the problem. Has anybody any ideas why a server should connect up to the intranet OK, but fail to connect to the internet at the same rate as other machines on the network? I have checked all the DNS settings, even tried using open DNS but this makes no difference to internet connection times from the server.

Any help greatly appreciated!

I hope you've already resolved this in some way by just in case here is the fix, it has to do with TCP Window Scaling being enabled by default in fc8 and up and having Cisco equipment that doesn't agree:

##
edit /etc/sysctl.conf and add the following lines


#Control TCP Windows Scalling
net.ipv4.tcp_window_scaling = 0

Thanks to krolaw for this fix, original URL as follows:
