Postfix error message

user · April 3, 2010, 6:00pm

Noticed in logs messages (ESC on boot) that postfix is failing
every time I boot. Only error I find in logs is:

Apr 3 07:05:04 linux-7utx postfix[3788]: fatal: parameter
inet_interfaces: no local interface found for ::1

Can any one tell me what it means and what to look for?

Thanks

::1 is the ipv6 equivalent of localhost. Do you have IPv6 enabled?

Yes it is enabled, do I need it disabled?

Do you have these lines in /etc/hosts?

127.0.0.1 localhost
::1 localhost ipv6-localhost ipv6-loopback

And is the lo interface bound to both 127.0.0.1 and ::1?

Hoe do I determine this?

Here’s what I have in hosts:
<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.

Syntax:

IP-Address Full-Qualified-Hostname Short-Hostname

127.0.0.1 localhost

special IPv6 addresses

::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.2 linux-7utx.site linux-7utx

Thanks for your response.

Here’s what I get for above command:

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:270 errors:0 dropped:0 overruns:0 frame:0
TX packets:270 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:21947 (21.4 Kb) TX bytes:21947 (21.4 Kb)

Is this correct?

Thanks.

Take a look at

I had the same problem

/etc/postfix/main.cf

comment out
inet_interfaces = all

Then it worked in my system

MarcoMeswara · March 24, 2011, 10:56am

This post is late but for the sake of the next newbie…

i solved this by setting in /etc/postfix/main.cf

inet_protocols = ipv4
inet_interfaces = all

tararpharazon · April 10, 2011, 12:00am

Thanks MarcoMeswara and swerden those worked for me.

Postfix wasn’t a problem in 11.1 or 11.2. the /etc/postfix/main.cf from 11.2 and 11.4 were the same.

I believe I tracked a root cause of my hosts file problem. My problem started Apr 6, 05:18 am, around the same time as a monthly cron job that updated the /etc/hosts file.

Why it caused a problem in postfix this time out of 100s is still a mystery.

Old thread, I know, but I had the same problem when I upgraded my system to 12.1. It is caused
by this line in the hosts file:


127.0.0.2 linux-7utx.site linux-7utx

or in my case:

127.0.0.2      Telcontar.valinor Telcontar

I just updated to 13.2 and postfix crashed with that error message

I change /etc/postfix/main.cf to :

inet_protocols = ipv4
inet_interfaces = localhost

And postfix starts successfully
*
I chose localhost because I didn’t want that postfix listens to all interfaces*
