Adding IP v6 Address issue

[Damo]

Hello!

I'm running a CentOS 7 VPS with Plesk 12.5.30 and I'm trying to add a IP v6 address, logging in with SSH using the command "ifconfig" the IP v6 address is there though adding it in the Plesk panel I receive the error below I've Googled though I cannot seem to find a resolution.

Error: ifmng failed: SIOCSIFADDR: File exists /sbin/ifconfig eth0 add 0000:0000::0000:0000:0000:0000/128 exited with non-zero status 1

If anyone has anything they could suggest that would be great!

Please check that you see this IP address in list after click to "Reread IP" button in Plesk.

 

[Damo]

I've tried hitting "Reread IP" though there's no luck.

 

[IgorG]

As far as I know you can add additional IP to VPS only from hardware node side.

 

[Damo]

Not to worry, the IP is showing when I SSH so it's definitely working I thought it would have been nice to have it show in Plesk.

My IP v4 shows.

 

[IgorG]

Try to enable debug mode in Plesk and run

# plesk bin ipmanage --reread

Check possible errors in output.

This is what I got back, the log is too long to post here so I've uploaded it in a .text

 

[IgorG]

Nothing interesting in log. Check that you have not

net.ipv6.conf.all.disable_ipv6=1

in /etc/sysctl.conf. Also try to use other netmask for this address. Contact Plesk Support Team if not help.

Hmmm....

My ifcfg-eth0 file is empty? Is it supposed to be?

 

[IgorG]

I don't know what's type of VPS do you have, but there is no /etc/sysconfig/network-scripts/ifcfg-eth0 file in Virtuozzo VPS. Only virtual network interfaces /etc/sysconfig/network-scripts/ifcfg-venet0 and /etc/sysconfig/network-scripts/ifcfg-venet0:0

I'll contact support, do you have link as to where I can contact them?

I'll contact support, do you have link as to where I can contact them?

Our official site is plesk.com
Go to Support there and you will find support form.

 

[Damo]

Ah found it, thank you for your help IgorG.

@IgorG

I spoke with support they told me it was because the IP address was dynamically applied to the server which with Linode I can't change... Anyway I was deciding between Linode/DigitalOcean and the IPv6 works fine with DigitalOcean so I think I'll move to DigitalOcean just quite literally because of this.

Just thought I'd update you.

Thanks again for the help.

 

[IgorG]

Thank you. It was interesting case.
