Static IP adress / offline operation of RP

[schaeds]

Hi all

Problem 1 - set static IP adress
I am not allowed to connect the RedPitaya to the companies network. That's the reason why I connect serveral RedPitayas over a second ethernet card to my computer. On my computer I have no DHCP server installed, so I would like to set the RepPitaya to a static IP adress.

Editing sections in files have all no effect:

Code: Select all

/ect/network/config                                                       
/ect/network/interfaces                             
/ect/network/interfaces.ap 

How can I set a static IP adress?

Problem 2 - How to use Apps (Scope) without Internet connection?
When I try to start an App I get the message "Licence verification failed!". As discribed, the RedPitayas have no internet connection (connected over local network). Is it not possible to use them offline? Within company networks, it's not possible to connect the Redpitayas to the internet.

Info: Using OS release 0.95

Kind regards
Stefan

Similar question here,
I do not have facebook, is there any other way of activating the oscilloscope application? (that is, when there is no facebook) ?

Hi Stefan,

I changed the file called eth0 in the directory /etc/network/networks.d

In the file I put:

Code: Select all

#auto eth0
#	iface eth0 inet dhcp

auto eth0
	iface eth0 inet static
	address 192.168.137.40
	netmask 255.255.255.0
	network 192.168.137.0
	broadcast 192.168.137.255
	gateway 192.168.137.1
	dns-nameservers 192.168.137.1

This worked for me.

Kind Regards,

Julian.

Hi Stefan,

In regards to problem 2:

RP does not have a RTC.

It looks for a NTP server at boot time to set the clock. If none found it sets clock to default.

In this case the licence becomes invalid.


Kind Regards,


Julian.

Hi Julian,
so, do I understand correctly that there is no way to activate the oscilloscope and other tools without internet?

Hi,

I have the same problem.
I found something in the FAQs. Maybe this could help...
look at http://redpitaya.com/faq-page/ -> Applications -> Manually downloading and installing free applications

Kind regards

You can manually set the clock of the Red Pitaya after boot. It should then be possible to use an already installed license without internet connection.

I changed the file called eth0 in the directory /etc/network/networks.d

Hi Julian

thanks for your help!! Unfortunately this solution didn't work for me.
I flashed a brandnew image to the SD card and all files I see on the SD card in /etc/ are:

Code: Select all

/etc/network/config
/etc/network/dnsmasq.conf
/etc/network/interfaces
/etc/network/interfaces.ap

Setting the configuration in this files has no effect. Your mentioned file /etc/network/networks.d/eth0 does not exists.. And if I create it, it has also no effect. Did I something wrong?

Thanks a lot!
Regards
Stefan

You are looking in the wrong partition. The first partition (fat32) is mounted in /opt/redpitaya/ at runtime. The folder /etc/network/networks.d/ is on the second partition (ext4) which will be mounted at / when the Red Pitaya is running. This partition is not accessible to windows OSs, because they don't have driver support for the ext4 filesystem.

Ok, thanks to all.. Finally I got it ..
I prepared the SD card under windows, that's the reason why I havn't seen the second partition..

But the file I modified for static IP was called /ect/network/interfaces.d/eth0

Kind regards
