Hello,

Using SL 5.4 ( 2.6.18-194.32.1.el5 ) from my apartment results in very 
slow DNS lookups -- on the order of 30 seconds for each new page. I am 
pretty sure the problem is with DNS because it goes away if I use vpnc 
to tunnel to Fermilab. Google led me to the following workaround: add

alias ipv6 off
alias net-pf-10 off

to /etc/modprobe.conf . This works, but the system now complains about 
some error with ipv6 tables when it boots. Is there a better way to fix 
this (without changing any router settings -- I don't have the password)?

Thanks.
