Dear Vaibhav, As far I know, For example if U add this in /etc/resolv.conf search redhat.com it would mean that when U want to place a query like ping mail.redhat.com due to the addition of the search keyword in resov.conf U could just type ping mail it would automatically ping mail.redhat.com Due to the ' search ' keyword it appends queried hostname to the domain mentioned next to search to every query U make Correct me If I am wrong ... Always waiting to upgrade myself .. Hope I am of some Help Regards, Shailesh Vaibahv wrote : --------------------------------------------------- Hi All, This sure is a too fundamental a question, and I could not get an understandable answer, hence I am seeking help here. What is the meaning of "search foo.com" & "domain foo.com" in resolv.conf resolv.conf contains a list of NS <as provided by ISPs> which will do domain to IP lookup... so then what will searched on foo.com ?? Diff. betwee search foo.com & domains foo.com Trying to set my fundas correct... No flames pls. Thank you. Vai =======================================================
