In addition to my comments made about the flaws in the new Microsoft "i-Pod killer" here It appears that there is a further limitation to the already next to useless wireless sharing feature. |

It seems that Acer have included a nice little security flaw as part of a remote support tool on many of their machines, at the moment we have confirmed this on several Aspire and Travelmate laptops. I'd imagine that the desktop machines are also affected. |

ADSL Routers and Kernel >=2.6.17 |

The 2.6.17 kernel has had an update to the TCP stack and Window scalling, the fix brings the kernel in line with the TCP/IP specification but unfortunately some home/office broadband routers are still broken in this respect. If after loading this kernel you find stange problems with internet connectivity then you need to either disable Window Scaling or adjust it back to the old values. First try this echo 0 > /proc/sys/net/ipv4/tcp_window_scaling If that works and you now have more reliable internet connectivity then you can make a better long term fix by making the following changes to /etc/sysctl.conf net.ipv4.tcp_rmem=4096 87380 174760
net.ipv4.tcp_wmem=4096 16384 131072 Now after a reboot all should be well (thanks to Brett Parker of ALUG for this tip) |
