[SATLUG] Slow Internet response on Linux boxes

[Gabriel Doss]

Thanks for the input, Borries. It turns out that somehow the Linux boxes
were enabled for IPv6. I do not know how this happened as they were not in
the past. Possibly an upgrade I pushed overrode that part of the
/etc/modprobe.conf file. I added "alias net-pf-10 off" and after a reboot
all the Linux boxes were happy again.

Thanks again,
Gabe Doss
