That much I knew ... it's a data file containing links between IPs and friendly names. But who uses it? > It will not resolve >name and address, only DNS does that, i.e. BIND. Right, but somebody uses the info in /etc/hosts, don't they? I thought (don't ask me where I got this idea) that bind (ie.named) looked in /etc/hosts first before going to an upstream DNS server. > The Hosts file will go >by IP addresses only, and not names/aliases.. Don't know what you mean by that. Is the "hosts" file only looked at by the machine upon which it resides, then? >This is more of a local >protocol on a small network, versus a DNS daemon, which is more global >going out onto the net, and working with several networks, and subnets. >This provides for reverse name and address lookup, with SOA's (start of >authority) records, etc...

Help me out here ... There's the DNS service, implemented by the application called bind, whose daemon is called "named", right? I know what that does, SOAs, A records, etc. It keeps a local, dynamic cache file with data that is aged according to instructions from the upstream server. It's just that I thought it also looked at the host file for local static info first. Who uses /etc/resolv.conf? Another daemon? Basically, how does a machine on the LAN get resolution to an IP from a friendly name for a) another machine on the LAN, and b) a machine somewhere out on the Internet ? Maybe if you could also tell me where WINS fits into all this, that would help a lot too! Please clear this up for me :-) julian. ====================== >-- >Best regards, >Gary > > > >_______________________________________________ >Redhat-list mailing list >[EMAIL PROTECTED] >https://listman.redhat.com/mailman/listinfo/redhat-list ============================== Julian A.
