  • Join Window 7 workstation to ClearOS7 domain

    This is a new server with all updates applied.

    And the workstation is a recent build and registered with MS. All updates applied.

    The server is homebase.home.htt (192.168.192.2)

    The client is on the same subnet (192.168.129.77) and can ping homebase.

    \\homebase.home.htt on the start programs box opens up explore showing all my shares and I have no trouble opening up public shares.

    I have made the registry hack via regedit. I go to Windows Explore> Computer > System Properties > Computer Name, domain, workgroup settings and select Network ID and follow the wizard.

    I have tried both HOMEBASE and HOMEBASE.HOME.HTT for the Computer Domain. The error I get is that teh AD DC cannot be contacted.

    What do I do to get the computer to join the server?

    thanks

  • I have a howto on setting up a Centos7 multidomain mail server at:

    http://www.htt-consult.com/Centos7-mailserver.html

    This is on a CubieTruck armv7, but it is Centos7 which SHOULD mean that you can install the whole suite on a ClearOS7 box.

    This is an improvement on my Redsleave6 mailserver. So I have been using this sort of setup for a lot of years.

    Just note that amavis and clamav can eat up 2 cores easily.

  • Yes, you have the ClearOS CA cert. This shows how to create server certs, using a private CA cert for signing. That is the 'key' part. I have plenty of examples of self-signing certs at:

    http://www.htt-consult.com/Centos7-mailserver.html

    I need to add running a private CA like the OP is asking.

  • postfix.org has an example of creating your own CA cert and then signing your own server certs with it. See:

    http://www.postfix.org/TLS_README.html

    section:

    Private Certification Authority

    I need to work some on developing this.

    Probably later next week.

  • Make sure you have adequate random entropy to strongly create all those certs. Consider installing haveged. In fact install it on all your servers, as randomness is needed for every TLS setup and message.

    I really don't think the cert management interface is rich enough. I don't expect to dig into this for a couple weeks so could be wrong on my assessment.

  • After base install, add windows networks and flexshare from the marketplace and you are set to configure your NAS. Set up for 'simple' windows file sharing and web access.

    Or you can run as a full NT-style domain PDC with roaming profiles support (how I do it).

    Re: Postfix not forwarding loqwatch report

    Yeah, telnet is like that; so easy to forget you have to provide a port. Been there, done that too often.

    z9m9z is only as complex as it needs to be. I run a number of virtual hosts from it. The challenge here is what has been done to the default Centos postfix configuration by ClearOS.

    I took a quick look at /etc/postfix/main.cf and saw that I had set the domain to htt-consult.com. That would convince postfix to do a local delivery. So I changed it to home.htt and ran a test with:

    sendmail -i rgm@htt-consult.com < xfce.lst

    and that was properly relayed through z9m9z. So the problem was mine in ClearOS in improper configuration of the Mail Settings dialog.

    One for your tips and tricks for those that use an external (to ClearOS) mail service. The ClearOS mail domain MUST be different from your external mail service domain.

    Oh, and if you want help developing a rich featured email service, I am available.

  • In my set up, ClearOS is not a gateway. It is just a server. And servers have processes that generate mail reports to forward to the admin.

    On a more 'normal' server setup, the server may well be in the same domain as all of the other systems, thus this problem. home.htt domain is just a hold over from my setup some 7 - 8 years back.

    I think a regular admin, would fall into the same setup I did.

    Say Google is hosting your mail service. And you have a Sonicwall gateway (my brother-in-law has a number of clients like this). Then you setup ClearOS as your file/print server and maybe another function or two (local Cloud?). I might think the common thought would be to use your domain name in the mail setup, just as I did. Should be some subzone like smb.foobar.com

    Anyway, one more little change. Now all I have to do is either buy one of the cheap OEM copies of Win7 and install it on an old box here, or buy a reconditioned box with Win7 installed. Then I can start testing out an actual client.

  • z9m9z.htt-consult.com is my mail server and receives emails from all over the world to port 25. Check that you are resolving to 50.253.254.3, as there once was a DNS secondary with old records from an old ISP, but I removed that server from the authoritative list a number of years ago...

    z9m9z is running Redsleave6 on a CubieTruck using Postfix etal. It replacement CubieTruck with Centos7-armv7hl is 'almost' ready (see http://www.htt-consult.com/Centos7-mailserver.html for the setup; I am having SELinux issues). It handles 7-8K emails per day. it is accessed both externally and internally (by IMAP clients and SMTP from internal servers).

    But if you look at the /var/log/maillog messages, Postfix did not even TRY to deliver the message to z9m9z. It made a decision that the mail was local, ignoring the domain in the TO: and dropped the mail into /var/spool/mail/rgm. So the challenge is on ClearOS to get it to recognize that it has to ship the mail out.

    1) Do you mean the smtp server inside of ClearOS (my hostname is homebase.home.htt).
    2) I do not want to run mail on homebase. It only is to deliver mail services like logwatch and cron generate ot z9m9z.
    3) It is open. I recieve too much spam from all over the world for it not to be open :)
