I would suggest manually adding a valid public name server: For instance: nameserver 8.8.8.8 nameserver 192.168.1.254 #Generated by NetworkManager domain home search home Then ping some site on the Internet, such as www.blu.org. Then try the telnet exactly like this: telnet www.google.com 80 Then copy the lines and paste it to the email. Additionally, try disabling both selinux and iptables. It is possible that these are blocking outbound port 80. -- Jerry Feldman <gaf@xxxxxxx> Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846
