It may be worth checking your router's firewall rules once more. Is the=20 gentoo box connected to the router in the same fashion as the MSWindows=20 boxen, or is it in some funny DMZ set up? What do the firewall logs show? > What things should I be checking. If as you say you have no firewall on the Gentoo box then you ought to have= a=20 quick look at your kernel. Use sysclt: /sbin/sysctl -a and look at your settings probably for net.ipv4.icmp_* or your specific NIC. > A ping attempt like this: > > ping ftp.ucsb.edu > PING ftp.ucsb.edu (128.111.24.43) 56(84) bytes of data. > > Just never moves any further, but you can see it has resolved the > alpha address to numeric forum so must have contacted and received > info from the nameserver. Or from your router if it acts as a caching DNS resolver? Unless you have configured your Gentoo kernel in a way that I am not sure i= s=20 possible, my money would go on something being amiss with the router firewa= ll=20 settings. =2D-=20 Regards, Mick --nextPart2982811.LjKi8JOfID Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEABECAAYFAkiDYKUACgkQ5Fp0QerLYPchfACeI5ezzd+3NVmIj9D+QHI9Tv84 3HAAoJ6RY5rVsATcjlzu3Lazd2WOrRvm =F1UT -----END PGP SIGNATURE----- --nextPart2982811.LjKi8JOfID--
