Hi ! sorry I forgot to mention . This problem happens when machine is idling ,no P2P or bit torrent running , skype is also not running. I already have wireshark installed . which provided me a class 3 ip address. Whois cant figure out it is . I also suspect a attack but this is my home machine and no body else has touched it . Since SELinux is enabled so security infringement should warn me right -- Regards Subhodip Biswas GPG key : FAEA34AB Server : pgp.mit.edu http://subhodipbiswas.wordpress.com http:/www.fedoraproject.org/wiki/SubhodipBiswas
