I have a RHEL server where I want to create a mail server so I can send myself alerts whenever X process have problems.
Disclaimer:
Im a programmer thats been forced to do IT. So I'm trying my best here.
The problem:
While configuring Postfix it asks for $myhostname which apparently must be in the format hostname.mydomain.com. I do have my $hostname but I dont know the "mydomain" part.
Do "mydomain" is something I create or its something I should get my the networks admins since the server is connected to my company's network?
If you need output from specific commands let me know.
/etc/sysconfig/network and /etc/hosts:
Thanks in advance!

When I connect to any IRC server, it's usually my ISP IP address/hostname. I own a domain, but I'm not using it for anything (no web hosting service or server). Is it possible for me to use my domain as my IRC hostname instead of my regular ISP hostname? (0 Replies)
I'm working on a rather large script atm (it already takes 9 arguments). As such, I need to obtain both a server name and domain from the FQDN. From this, I want to both populate the hostname of the server, as well as the domain line in the /etc/resolv.conf file.
Obviously, this isn't working. I... (10 Replies)

HOSTS(5) Linux Programmer's Manual HOSTS(5)NAME
hosts - static table lookup for hostnames
SYNOPSIS
/etc/hosts
DESCRIPTION
This manual page describes the format of the /etc/hosts file. This file is a simple text file that associates IP addresses with hostnames,
one line per IP address. For each host a single line should be present with the following information:
IP_address canonical_hostname [aliases...]
Fields of the entry are separated by any number of blanks and/or tab characters. Text from a "#" character until the end of the line is a
comment, and is ignored. Host names may contain only alphanumeric characters, minus signs ("-"), and periods ("."). They must begin with
an alphabetic character and end with an alphanumeric character. Optional aliases provide for name changes, alternate spellings, shorter
hostnames, or generic hostnames (for example, localhost).
The Berkeley Internet Name Domain (BIND) Server implements the Internet name server for UNIX systems. It augments or replaces the
/etc/hosts file or hostname lookup, and frees a host from relying on /etc/hosts being up to date and complete.
In modern systems, even though the host table has been superseded by DNS, it is still widely used for:
bootstrapping
Most systems have a small host table containing the name and address information for important hosts on the local network. This is
useful when DNS is not running, for example during system bootup.
NIS Sites that use NIS use the host table as input to the NIS host database. Even though NIS can be used with DNS, most NIS sites still
use the host table with an entry for all local hosts as a backup.
isolated nodes
Very small sites that are isolated from the network use the host table instead of DNS. If the local information rarely changes, and
the network is not connected to the Internet, DNS offers little advantage.
FILES
/etc/hosts
NOTES
Modifications to this file normally take effect immediately, except in cases where the file is cached by applications.
Historical notes
RFC 952 gave the original format for the host table, though it has since changed.
Before the advent of DNS, the host table was the only way of resolving hostnames on the fledgling Internet. Indeed, this file could be
created from the official host data base maintained at the Network Information Control Center (NIC), though local changes were often
required to bring it up to date regarding unofficial aliases and/or unknown hosts. The NIC no longer maintains the hosts.txt files, though
looking around at the time of writing (circa 2000), there are historical hosts.txt files on the WWW. I just found three, from 92, 94, and
95.
