I have implemented this plugin

https://github.com/coriaweb/cwpipv6/

I have this IP subnet of /64
how can i use this script to add it to server?

Can i change the code in the ipv6_list.php to 

<select name="ipv6range">
<option value="64">64</option>
<option value="112">112</option>
<option value="120">120</option>
</select>
 

If my ip rrange is:
1a01:4f8:221:34c2:: / 64
can i just input:
1a01:4f8:221:34c2::
in the input field and chose the dropdown and 120?

I dont need 65000 adresses, only 256 and that would be more than needed.

Aalso when i try this and go to assign IP the dropdown only lists 1 field, should the complete range be visible?

it just says:
1a01:04f8:0221:34c2:0000:0000:0000:0000/112
and thats the only field/line

this module only works with /112 so you will need to modify the file

 nano /etc/sysconfig/network-scripts/ifcfg-eth0

to subnet your network to a /112 prefix

You will need to add something like :
IPV6ADDR=2a01:4f8:c17:1b52::1/112  // only an example

then do

sudo systemctl restart NetworkManager

then

ip addr show eth0

to see the changes

this is translated copy in English

I didn't test the module on live servers yet.

  • Viable migration script for CWP server migration available?

    I really look for an automated server migration script, alone the installation of all the software installed on the source server would take me days, function not guranteed. The current status is, that I tried that already, and the result is: CWP working, transferred websites not working fully, email not working.
    That can not be the solution
    There must be a working transfer script out there, no matter what you have on the source server, just using rsync and changing IP adress/hostname everywhere it is referred to.
    Am I the only one who has this problem?

    I usually install cwp first and do this and it works every time, different hardware doesn’t matter and the kernel will take care of it.
    in some cases efi boot cause issues
    in this situation move the users manually

    How to easily migrate local users and groups from one sys...
    All local users and groups (within a certain UID/GID number range) need to be migrated from one old system to another freshly-installed system without manually creating said users on the new system.

    that is what I have right now, anyone may find something I overlooked….
    At least it is rebootable, though database and cwp NOT working at all, nor websites.

    also if you just rsync etc your system wont boot anymore, as target server has different hardware for sure.
    Think it needs a more granular response.

    Thanks Sandeep
    Seems you forgot CWP itself in this approach, as well as other installed software.
    Can you advise a script doing all this and running out of the box. Already did something similar but always got stuck up to now.
    Th farthest I got was CWP running by manual install and websites running partially but not all links working.
    But I really need a one to one copy by rsync, yet take care of the different IP and hostnames, and hardware specifics (shouldnt rsync /boot….). Thought it was less difficult, but no one a solution? Seems I am the first one to migrate a CWP server? No working script out there?

    Ling,
