No, I just run a nameserver that checks the IP addresses against an authenticated list.


Not clear got what that mean. I know in antispam system use checking back zone to resolve name of mail server. Is it something like this ?

Whatever, where is suppose to get some realy good courses for study linux... for study security in linux ?
I mean not courses for hiring like administrator but like advanced user ?
Thanks!
