ResNet Linux Fix

Computers running any distribution of Linux with the 2.6 kernel (including UBLinux 4.0 and Red Hat Enterprise Linux 4) have been found to experience severe slowdowns in network connectivity on ResNet. If you are experiencing unstable network access, follow the steps below to apply a fix for this problem.

  1. As superuser, edit the /etc/rc.d/rc.local file. You can use a text editor like Emacs in a terminal to do this.
    NOTE: On some Linux systems, the file might be located at: /etc/rc.local. Ubuntu 6.1 is known to have the rc.local file located there.

  2. Add the following line to the end of the file:

    echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime

  3. Save the file, and restart your computer. The fix will now be applied on every system startup.

NOTE: UBLinux 4.1 will include this fix.
