Perfect Install - Ubuntu 6.06 Dapper Questions

Alright, I've setup A-Record for DNS as server.crossfirenow.com and ns0.crossfirenow.com -- if I ping those, it points to my external IP. Here's the problem, for some reason, it must not be pointing to the right ports on it now -- www.crossfirenow.com points to those 2 DNS, but -- there's no web display. If I http://192.168.0.100 -- I get apache server showin' up, http://www.crossfirenow.com timed out. Any ideas on why that's not showin' up?

 

ya, that was the problem, the ports needed to be forwarded -- I thought DMZ automatically let the machine free from the need of forwarding all those ports.

 

It depends on your router. Some routers call a DMZ what in fact isn't a DMZ...

 

Here's a question out of curiousity: why is the install of SSH and OpenSSH server placed before the networking stuff?

Maybe it's just me, but it seems easier to not have to use the install CD and to let apt find it via the network. So more like in the Breezy install, do it after setting up the network.

Comments?

 

Because you can then check out your current IP address with

Code:

ifconfig

and connect to your server on that IP and copy and paste the networking stuff. Saves you typos.

 

Brilliant, thanks!

 

When installing Postfix (apt-get install postfix postfix-tls libsasl2 sasl2-bin libsasl2-modules libdb3-util procmail) I get the error message that postfix-tls is covered with postfix 2.2.10-1ubuntu0.1 and that there is no installable candidate for postfix-tls.

Should I just ignore the error, or do I need to do something special?

After completing the guide it now seems that I cannot receive (and probably not send) e-mails anymore.

Here's /var/logs/mail.log on a testmail that seems to have been received, but did not trigger creation of my maildir:

Pointers are much appreciated, as I really need to get my e-mail back up and running!

 

You are the third who reports this, but I swear it worked for me the way described in the tutorial.
Anyway, go on and check if you see TLS in the output of

Code:

telnet localhost 25

later on.

 

Here's the output and it seems to be in there:

root@oldcourse:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 oldcourse.mydomain.net ESMTP Postfix (Ubuntu)

Hope this helps.

 

Thanks for your quick response! I tried to connect using uebimiau webmail and it just will not let me log in (yes, the user id and password are correct ). And since I don't seem to receive e-mail, my maildirectory is not initialized. At least I don't see it in web4_me/...

I have received a new e-mail and looking at /var/log/mail.log it seems as if it's being moved to admispconfig@localhost instead of the real user. So what do I reconfigure to change that?

Well it seems I finally figured it out In order to receive mail I needed to enable Maildir in the Management -> Server -> Setup section. Makes sense as I'm using Courier which as far as I know only uses Maildir.

Now I'm running into the problem that I cannot send mail. Here's the output from /var/log/mail.log:

My ISP uses mail relay for sending e-mail, so I have added this line to my setup:
postconf -e 'relayhost = mailrelay.direct-adsl.nl'

On my Breezy mailserver I had the following line as well (ISPConfig was not installed on that machine):
postconf -e 'smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, permit_sasl_authenticated, check_policy_service inet:127.0.0.1:60000, permit'

Again, help/pointers are much appreciated.

 

Disclaimer: I am very very new at this (long-time Windows user, new to Linux).

While trying to find a solution to the dreaded postfix-tls issue, I stumbled across this thread and I'm confused with the whole "domain" vs. "host" thing.

For example, while installing Ubuntu, it asked for a 'domain' to identify itself to my network. Sticking with my network naming scheme, I called it 'delirium', figuring this was akin to naming my Windows machines on their workgroup.

However, if I'm reading correctly, at some point, I need to edit /etc/hosts to reflect the actual URL of the domain name I plan on hosting on this box (eg. mydomainname.net)?

So should my hosts list look like this?

Code:

127.0.0.1       localhost.localdomain localhost
192.168.1.110   delirium.mydomainname.net delirium

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Am I understanding correctly that 'delirium' is in fact the "name" of this machine and having 'delirium.mydomainname.net' doesn't mean that visitors will have to type that in their browser to access my site when I finally unleash it to the world? Or could I just leave it as 'delirium' and specify the hosted domains later? (This gives me a headache...)

 

Make sure you enable "Server requires authentication." in your email client.

Have a look here: http://www.howtoforge.com/forums/showthread.php?t=72&highlight=relayhost

 

Yes.

delirium is the hostname, and delirium.mydomainname.net is the FQDN (fully qualified domain name). Your user must use the FQDN in their browsers.

 

This error occurs when using the webmail client. When enabling this setting in Thunderbird (my prefered mail client) it no longer allows me to log in. Strangely enough the same happens when I change the security setting from "TLS, where possible" to "TLS" or "SSL".

I have followed the copy/paste Perfect Ubuntu 6.06 setup.

Will do.

 

Thanks for the speedy reply!
So if I just wanted them to be able to use mydomainname.net or www.mydomainname.net, would I then change it to this?

Code:

127.0.0.1       localhost.localdomain localhost
192.168.1.110   mydomainname.net delirium

Am I understanding correctly that 'delirium' will be used as (sort of) the internal network name for that server, but DNS lookups will resolve mydomainname.net to that IP (assuming I've got it setup with the registrar and my router)?

 

This is the weird thing: I'm not getting an error in /var/log/mail.log when I change the setting in Thunderbird to: "TLS" or "SSL". It just tells me that the IMAP server doesnt like me trying to connect and that's it.

In the meanwhile I was able to test that mail within my domain works, it just seems that sending outside of mydomain.net does not work. This is what I (additionally) had in my Breezy setup, where I used virtual users managed in a MySQL database:

postconf -e 'mynetworks = 192.0.0.0/8'
postconf -e 'relayhost = mailrelay.direct-adsl.nl'
postconf -e 'smtpd_sasl_auth_enable = yes'
postconf -e 'broken_sasl_auth_clients = yes'
postconf -e 'smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination'
postconf -e 'smtpd_use_tls = yes'
postconf -e 'smtpd_tls_cert_file = /etc/postfix/smtpd.cert'
postconf -e 'smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks, reject_non_fqdn_recipient, reject_un
known_recipient_domain, reject_unauth_destination, permit_sasl_authenticated, check_policy_service inet:127.0.0.1:60000, perm
it'
postconf -e 'proxy_read_maps = $local_recipient_maps $mydestination $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks'

It seems to me that what I'm missing now (due to the fact that I need to relay the stuff I guess) in particular is this:
postconf -e 'smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks, reject_non_fqdn_recipient, reject_un
known_recipient_domain, reject_unauth_destination, permit_sasl_authenticated, check_policy_service inet:127.0.0.1:60000, perm
it'

Here's the errorlog for when I change my SMTP seetings on mail.mydomainname.net from "TLS" to "TLS, where possible"

Somehow I get the impression TLS is not working correctly....

Update 21:30
TLS does not seem to be the biggest issue. The laptop I'm using is running Symantec Internet Security (Corporate Edition) and they really don't like encrypted mails. So after disabling that in the virusscanner and deactivating the firewall it now appears that I cannot connect to the SMTP server. Again, no error message in /var/log/mail.log.
