imap server can't locate localhost

Does anyone know how to solve this problem?!
I've try to run command imapd, postfix, authdaemond and apachectl.
But, when I try to open it. It'll appear warning sign like as my title was.

Either you don't have the following in /etc/hosts:

Code:

127.0.0.1    localhost

or those daemons are running chroot'd and you don't have a copy of /etc/hosts inside their chroot (for instance, /var/spool/postfix/etc/hosts in the case of Postfix).

still confuse.
What do u mean about don't have a copy /etc/host ?!
I'm using localhost like as you said 127.0.0.1.
Anyway this is warning sign that client accept it
"Error connecting to IMAP server: localhost.
49 : Can't assign requested address"

network devices communicate with each other by IP addresses. in your case the server is searching for an ip address of the host localhost. this information is saved in a /etc/hosts file. 127.0.0.1 ip address points the machine to itself whatever the ip address that it has.

try to do:

Code:

ping 127.0.0.1

if it came back with a reply that means your tcp/ip stack is installed properly.

then try :

Code:

ping localhost

if you got replies that means that your /etc/hosts file is good to go. if you didn't get any replies, that will requier you to edit /etc/hosts. here is /etc/hosts file from my machine:

Code:

# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.  Just add the names, addresses
#               and any aliases to this file...
#
# By the way, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1
# should NEVER be named with the name of the machine.  It causes problems
# for some (stupid) programs, irc and reputedly talk. :^)
#

# For loopbacking.
127.0.0.1               localhost
# End of hosts.

if you have the same information in your file, ther must be a firewall running on your machine. most likely it's iptables.

try above and if you have a problem post back

O yeah, I'm forgot to tell you. When I try to ping localhost the message appear "can't assign requested to address".

try this:

Code:

ping 127.0.0.1

then tell us what happens...

jariknet · 01-12-2007, 10:19 AM

appear "can't assign requested to address"

i have some guesses:

1- tcp/ip is not installed correctly with your os...
2- lo interface have been deleted for whatever reason....
3- your network card is messed up or the driver for the network card can't be located.
from the shell, type:

Code:

ifconfig

and post the output..

to view a list of pci devices, type the following and post the output:

Code:

/sbin/lspci

try to ping something else on your local network ... like your gateway or something.
what dist you're using? did you install the os yourself or somebody else did?

jariknet · 01-12-2007, 05:17 PM

There are ed0, plip0 and lo0 if I try command ifconfig -a. And there are still running.
About lspci I can't find it in sbin directory it isn't there.
