Clonezilla not booting with static IP address.

Hello all,

Happy New Year!

I am using the omv-extras plugin: Clonezilla, to perform headless backups of my system disks. I have used it with no problems in the past (OMV4), when I have chosen single boot to Clonezilla kernel from the web GUI and then rebooted, it always kept the Ip address that I had asked my router to assign to it. I then remotely ssh'd into the server, logged in and used Clonezilla. When done, I logged out and rebooted, the web GUI was then available again.

I have two fairly fresh installs of OMV5 on Dell PowerEdge R210 II servers and when I choose the Clonezilla kernel from the web GUI and reboot, it loads up fine, but I cannot access it remotely via ssh - it looks like it has lost the IP address.

Its really cold in my garage (where the servers are), in the winter so I'd like to be able to do the headless backup again via ssh! Any help would be greatly appreciated.

Thanks,

Nick.

Hi,

Thank you, yes, that's what I thought; that the router is handing it out a random address. The thing is that the router will always assign the correct IP address when rebooting normally. Its only when I ask it to boot from the Clonezilla kernel that this seems to happen.

Here's a pic of my DHCP reservations:

Top one is my printer, then:

OMV4

OMV4

OMV5

OMV5

I have tested all of the OMV5 installs (3 of them now) on 2 X Dell PowerEdge 210 II servers and 1 X Dell PowerEdge 310 server) and they all suffer from the same issue. Its weird (and I'm cold).

The two OMV 4 installs are on a pair of old desktop computers and they reboot fine.

I'm lost!

Thanks,

Nick.

EDIT: One extra thing that I have just thought of: In the web GUI - System/Network/Interfaces, I have just left the settings as IPV4: Method:DHCP - there is no need for me to set a static IP here, is there?

OK, so will it assign that same IP every time?

Thank you for your help,

Nick.

EDIT: Oh, hang on - I guess I look up the IP and then add that to the DHCP reservations in the router?

OK, thank you for this.

The router doesn't seem to be listing the new IP address.

I used to have a nice Linksys router that I flashed with ddwrt and ran Mullvad VPN on but that was when I had a very slow 4G connection and we now have two routers with our new fibre ISP - Linksys Velops. Great routers and they give us great coverage throughout the home but they came with the 192.168.1.1 IP address that I had assigned to the ddwrt router and I just didn't have the energy to learn how to set everything up again, so I just plugged it and and stuck a VPN app on the computer.

Maybe I should look into setting that up again, but I have downloaded Nmap first. Thing is, how do you use it?

I looked at this guide and it says to scan and list a local range of network IPs, assuming your LAN has an IP range of 192.168.0.1 to 192.168.0.25, (change those numbers as appropriate), you'd enter

nmap -sP 192.168.0.1-25

So here is my network info from the router:

So I entered:

nmap -sP 192.168.1.1-245

... and then tried to ssh into any IPs that I didn't recognise, but no dice there.

Am I anywhere near doing what I am supposed to do here?

Thanks,

Nick.

EDIT: Okay, looking at this again, I think it should be nmap -sP 192.168.1.10-245 but that's not giving me anything either.

Thanks, I ran that and I could see the IP addresses of the printer and servers that are currently running normally, and they were all reporting:

PORT STATE SERVICE

22/tcp open ssh

There were a few other entries that I didn't recognise, example below:

Nmap scan report for 192.168.1.31

Host is up (0.039s latency).

[tt]PORT STATE SERVICE

22/tcp closed ssh

Obviously, I'm not going to be able to ssh into these if port 22 is closed, I'm not sure what to do next in finding the IP?

OK, many thanks or this - at least I know where I am now.

I had no idea that it might not even have an address.

Maybe I'll try to figure out. way to get the ddwrt router back on the network but it make my mind boggle a bit - I'm still new to all this!

All the best,

Nick.

OK, thank you for that and I will dig it out of the garage and see what I can do. I'd much rather the VPN was back at the router, in any case.

Thanks again for all your help, and also your excellent guide on backing up headless servers using Clonezilla - its a weight off my mind to be able to clone the system drives, even if its in the cold garage for some of them!

Cheers,

Nick.

Hi, amedangela,

OK, I will try to replace the router today and let you know.

Cheers,

Nick.

Hi,

i solved few mins ago; checking on the router i noted that after rebooting with clonezilla it takes same static ip address of OMV but with hostname "debian"; by starting an ssh session with hostname connection worked fine.

OK, so for this would you just enter:

ssh user@omvhostname and password: live?

Thanks,

Nick.
