    VLAN and Virtual IPs

    Is it possible to have a physical interface VLAN'd and the one of those VLAN having an additional virtual IP




    What I would like to do is add Virtual IP, 10.10.11.1 to eno2.100.

    I can't just add it to eno2 as the layer 3 switch rejects the packets. So can I create an eno2.100:1 = 10.10.11.1

  • For any one looking for the answer for this the solution was to put the

    into the dhcp.conf file for the visitor network.

    That way any Avaya phone coming into the switch gets tagged as VLAN 200 and so served an address by the VLAN 200 DHCP server.

    Avaya VOIP handsets, VLANs and DHCP

    We have upgraded our COS v5 to V7.3 and now our Avaya handsets are not getting the correct address from the ClearOS.

    There are four physical interfaces, External, LAN, Corporate WAN and Visitor. - IP Settings.PNG

    The LAN interface is set up for three VLANs with no IP address on the physical interface.

    VLAN 100 - LAN
    VLAN 102 - Second LAN
    VLAN 200 - VOIP


    DHCP is enabled on two of the VLANs and also the Visitor interface. - DHCP-Settings.PNG

    A handset plugged into port 5 on the switch is being served an address from the Visitor LAN.

    Excerpt from Switch Config file:

    Relevant bit of DHCP.conf

    At the moment we are manually setting the IP address for each handset.

  • OK, thanks for that, it makes a lot of sense.

    I am trying to get Avaya handsets to get a DHCP address in the correct VLAN/subnet and had added a line to the dnsmasq.conf file and just wanted to restart the service without restarting the server.

    Still not working as planned on a handset level, but that's a topic for a new thread.

    I don't know that the term 'oversight' is appropriate here. DNSmasq not only provides DHCP services but it is also the foundation for a number of services which required a functioning DNS server. The services include:

    Samba
    Gateway.Management
    DNSThingy
    ...and every single update including security updates.

    Simply stopping in essentially breaks a number of things. If you are skilled enough to compensate for these by properly assembling a replacement or by over the architecture of the DNS of the server with some replacement then it will also be trivial for you do the other types of things that does whatever it is that you need to do. Some of these other tasks include:

    Disabling the consumption of port 53 by DNSMasq by setting the port parameter to '0'.
    Rolling in Bind and DHCPd from ISC because you want to use them instead.

    The purpose for not having the start/stop button is to save people from breaking essential functions of the system. Feel free to do it manually but having that button NOT there is a good thing and will save a lot of heartache for those people who don't know/realize that the DHCP services is also the same thing that is making it so that there server can run DNS resolution on their updates.

  • I know this is an OLD thread but it seems like the "oversight" still hasn't been fixed.

    Are there any plans to do so?

    That looks to be an oversight...DHCP is provided by the Dnsmasq package, but there's no stop/start button for DNS either.

    Workaround...install the app "Services" from the Marketplace. There you can stop/start any registered service...DNS Server (aka dnsmasq) included, which, as I just mentioned, provided DHCP too.

    B


    So where can we get this reported as a "oversight" to be fixed?

    I tried the command in full from a command line with --verbose added as a parameter. I've also tried just the latter half of the command



    In both cases it just sits there, no output no nothing.

    Adding --logfile=SOME

    No file was created.

    Using it to backup localhost

    I have used BackupPC to backup a COS system to itself before, it was being used in parallel to Bare metal for full disaster recovery, and it worked fine.

    I'm now trying to put it in place on a system that has the Active Directory Connector installed.

    It runs but any attempt to backup the server fails with:



    Totally lost as to how to fix this.

    If this sounds like it'll work for you, and you need any help, feel free to ask.

    I'm liking what I see but can't work out how to install.

    Is there an easy way to install on ClearOS?

  • You're probably going to need the Active Directory Connector to get your AD users to show.

    https://www1.clearos.com/marketplace/server/Microsoft_Active_Directory_Connector#marketplace

    We've implemented this and now all users in the AD show in the ClearOS

    Not sure how it will fit your requirements but have a look at the Backup PC module, there is documentation on how to set it up for backing itself up.
