Getting nuts. Can't receive e-mail and can't configure a dns server (virtual host)
Please!!!! i really need help!!!
Look, i just can't config a virtual host on apache. What i need is simples, people who access www.demorgan.com.br go to http://my_ip/demorgan/ but people who are accessing www.demorgan.com.br are getting into http://my_ip/
Dns looks like this:
Code:
$TTL 86400
; Authoritative data for demorgan.com.br
;
@ IN SOA localhost. root.demorgan.com.br. (
2004102897 ; Serial (yymmddxx)
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
36000 ; Expire 10 hours
86400 ) ; Minimum 24 hours
IN NS ns1.demorgan.com.br.
IN NS ns2.demorgan.com.br.
200.138.31.116 IN MX 10 demorgan.com.br.
www IN A 200.138.31.116
ns1 IN A 200.138.31.116
ns2 IN A 200.138.31.116
Apache looks like this:
Code:
NameVirtualHost 200.138.31.116
<VirtualHost 200.138.31.116>
ServerName www.demorgan.com.br
DocumentRoot "/var/www/demorgan"
</VirtualHost>
Second problem
I can send e-mail using postfix without any problems but i'm not receiving e-mails...
I think this a dns problem. Look at the configuration above, is it right? |

That's because you didn't setup an MX record correctly in your zone file:
Code:
IN MX 10 demorgan.com.br.
As for the virtual server problem I don't see any difference between the 2 URLs |

Ok, this is the error i get when i send a e-mail (using gmail for example) for my domain.
Code:
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
demorgan@demorgan.com.br
Technical details of permanent failure:
PERM_FAILURE: DNS Error: DNS server returned answer with no data
On postfix, things are like this..
Code:
Feb 9 16:20:02 localhost postfix/pickup[11873]: 3C17A9E24: uid=105 from=<smmsp>
Feb 9 16:20:02 localhost postfix/cleanup[12156]: 3C17A9E24: message-id=<20060209182002.3C17A9E24@demorgan.com.br>

Feb 9 16:20:02 localhost postfix/qmgr[8498]: 3C17A9E24: removed
Is it normal? |

1. For thhe DNS problem:
Did you change your zone file, increase the serial and restart bind? Edit the zone file changing the following lines:
Code:
2006020901 ; Serial (yymmddxx)
...
IN MX 10 demorgan.com.br.
IN A 200.138.31.116
...
I haven't use postfix so I cannot understand the logfile but the error message is obvious
2. About vhost
If /var/www is your DocumentRoot then rename your server to something else(i.e. ServerName www1.demorgan.com.br) so when someone visits www1.demorgan.com.br goes to /var/www and when he visits www.demorgan.com.br goes to /var/www/demorgan, but I think it's better to use a different directory for each vhost(i.e. something like /var/www/default for www1 and /var/www/demorgan for www) |

Code:
<VirtualHost www.demorgan.com.br>
ServerName www.demorgan.com.br
DocumentRoot "/var/www/demorgan"
</VirtualHost>
The paramater for the VirtualHost entry is what tells Apache that requests for this URL go to the specified directory, the ServerName entry is just what Apache reports back to the client, *after* it has fulfilled the request.
As a note, typically a virtual host is for a unique directory, not one in another web site's subdirectory. So if you have a web server hosting two sites, site A would be someplace like /var/www/htdocs_site_a and site B would be /var/www/htdocs_site_b, not /var/www/htdocs_site_a/subdirectory_b.
As long as the appropriate domain names resolve to the correct IP address(es) then DNS should not be an issue for the web sites.
Mail is something I don't know enough about to comment on, but it looks like others have helped address your issues there. For the DNS aspect, I'd have something like this in the zonefile:
Code:
$TTL 86400
; Authoritative data for demorgan.com.br
;
@ SOA demorgan.com.br. demorgan.demorgan.com.br. (
; the second name is domain master's email, in this case
; demorgan.demorgan.com.br. means demorgan@demorgan.com.br
2004102898 ; Serial (yymmddxx)
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
36000 ; Expire 10 hours
86400 ) ; Minimum 24 hours
NS ns1.demorgan.com.br.
NS offsitedns.someotherdomain.com.br.
; the point of having two nameservers is redundancy, so there really
; is no point listing two and pointing them both to the same host.
MX 10 mail.demorgan.com.br.
@ A 200.138.31.116
;only one A record for each host, then aliases (CNAMEs)
;for anything else that resolves to that host
www CNAME demorgan.com.br.
ns1 CNAME demorgan.com.br.
mail CNAME demorgan.com.br.

Verify whether it's a problem in DNS or Apache. If both domain names resolve to the correct IP address, then the problem is in the Apache virtual host settings. Also, did you restart Apache after modifying the settings? |

That definition is wrong. You should use an IP address, or at least the * inside the <VirtualHost ..> for name based vhosts. The configuaration in your first post is OK, but use different directories as DocumentRoot for every server.
What about your email prob? |

But then i should have i CNAME in dns server, right? I think this is the problem.
using this config
Code:
$TTL 86400
; Authoritative data for demorgan.com.br
;
@ IN SOA demorgan.com.br. fernando.demorgan.com.br. (
2006020904 ; Serial (yymmddxx)
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
36000 ; Expire 10 hours
86400 ) ; Minimum 24 hours
IN NS ns1.demorgan.com.br.
; IN NS ns2.demorgan.com.br.
IN MX 10 mail.demorgan.com.br.
@ A 200.138.31.116
www IN CNAME demorgan.com.br.
ns1 IN CNAME demorgan.com.br.
I really don't know what i have to do  |

In this config you haven't define mail.demorgan.com.br. Define as an A record (better) or CNAME:
Code:
mail IN A 200.138.31.116
and of cousre you must also define the reverse-zone file to be able to resolve 200.138.31.116 to mail.demorgan.com.br as it is a mail server. Create the reverse zone file using something like:
Code:
116.31.138.200-in-addr.arpa. IN PTR mail.demorgan.com.br.
or
16 IN PTR mail.demorgan.com.br.
and add also the entry for the reverse zone file in your /etc/named.conf |

I really don't know how to do it. If you help me, i would appreciate.
About Virtual Host, they still now working. Should i define something like
Code:
www IN A 200.138.31.116
www IN CNAME demorgan.com.br.
Because just setting
www IN CNAME demorgan.com.br. doens't seen to work. |

First things first.
Edit your /etc/named.conf and add an entry under your forward zone (the one for demorgan.com.br) like this:
Code:
zone "0.31.138.200.in-addr.arpa" {
type master;
file "0.31.138.200.in-addr.arpa";
};
I don't know what is your IP chunk so I put 0.31.138.200.in-addr.arpa which is valid if you have assigned a whole 200.138.31.0/255.255.255.0 network. If that's not true then change it accordingly replacing the "0" with your first assigned IP. Anyway you can contact your ISP for help.
Then edit your forward zone (don't forget to increase the serial):
Code:
$TTL 86400
; Authoritative data for demorgan.com.br
;
@ IN SOA demorgan.com.br. fernando.demorgan.com.br. (
2006020905 ; Serial (yymmddxx)
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
36000 ; Expire 10 hours
86400 ) ; Minimum 24 hours
IN NS ns1.demorgan.com.br.
; IN NS ns2.demorgan.com.br.
IN MX 10 mail.demorgan.com.br.
demorgan.com.br. A 200.138.31.116
www IN CNAME demorgan.com.br.
ns1 IN CNAME demorgan.com.br.
mail IN CNAME demorgan.com.br.
Then create the 0.31.138.200.in-addr.arpa file:
Code:
$TTL 86400
$ORIGIN 0.31.138.200.in-addr.arpa.
@ SOA demorgan.com.br. fernando.demorgan.com.br. (
2006020905 ; serial #
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
36000 ; Expire 10 hours
86400 ) ; Minimum 24 hours
IN NS ns1.demorgan.com.br.
116 PTR mail.demorgan.com.br.
Restart bind and see if you can resolve hosts and IPs
Code:
nslookup www.demorgan.com.br
nslookup mail.demorgan.com.br
nslookup 200.138.31.116
I hope there is no typo in this and everything will work. |
