 Internet slow - some hosts only Hello: I am having a problem that I am unable to resolve. When I connect to www.hotmail.com or www.linuxquestions.org, the connection speed drops to 11B/sec (yes, eleven bytes). When I connect via WinXP (dual boot laptop :-G ) the connection is fine. Any ideas? has my box been hijacked? Am I serving as a proxy to someone? Any ideas? iptables ACCEPT EVERYTHING does not help... ??? Many thanks!      |

Try: echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale If it does fix it, make it permanent by adding a line like: net.ipv4.tcp_default_win_scale = 0 to /etc/sysctl.conf.

What I don't understand from the article is, then, the gentoo-dev-sources is broken then? I'll do some research now and see what's going on. Many, many thanks. I have an invite for GMail, by the way, maybe you're interested on it. Not working with Konqueror (because of the JScript) but works with mozilla. (Maybe you're lucky and you can get a good name for your EMail...) Just let me know! Many thanks! |

If you do a tcptraceroute with window scaling both enabled and then disabled you should be able to identify the broken router. You can whois it's ip and complain at the relevant sysadmin responsible for it. > I'll do some research now and see what's going on. > > Many, many thanks.

I already have a gmail account thanks, I'm in the market for a dual layer DVD burner though... :> -- Simulations are like miniskirts, they show a lot and hide the essentials. -- Hubert Kirrman |
