Static ipv4 problem

[leofabri]

Good Sunday to all, I started this post because I have a problem with my internet site. Unfortunately I have an internet line that is very unstable and often does not work. when it does not work, the ip address of my home router changes. when the internet is up and running, it changed the ip of the server, so the service no-ip can not find the new address so the website is wrong. is there a way to always keep the same ip? (I have already set the static ip in raspberry).

I hope you understand what I wrote (my english is bad)

The only way for your external IP to be static is to contact your ISP and request it. Static IPs usually cost more (Given the dwindeling number of IPv4 addresses), so you better contact them about your stability issues.

Thank you for your response. So there is no other solution to make sure that the ip address marked on no-ip change automatically when the connection is restored?

An alternative is to accept that your IP address will change.

Then use an external Dynamic DNS server to hold a static DNS name which resolves to the current address. External users will then refer to your services by DNS name.

Hello,

I haven't used no-ip for several years and then it was on a Windows machine, but I seem to remember that there is a small program on your machine that automatically sends your ip address to no-ip. I can't remember if it runs at set intervals or just on startup.

You could write a script that tests if your ip address has changed, and if it has changed, call the no-ip program, which will update their servers with your new address. Use crontab to run your script, say every 5 minutes.

NO-IP supplies a Linux script that will run on your RPi.

sudo apt-get install noip2
Or build from source: http://www.noip.com/support/knowledgeba ... te-client/

In fact, I had already installed on my noip2 raspberry pi and is still active, but the ip keeps changing.

Hi,

If you have noip2 installed, then the next question is whether it is configured correctly.

What have you set the update interval to ?
Is noip2 pointed to the correct domain name - <yourname>.noip.com
Have you got the correct username and password set.

Look at http://manpages.ubuntu.com/manpages/pre ... ip2.8.html

I noticed that the outgoing communication uses port 8245 - is this open

you were right it was remained the old configuration of the old host. how do I set the new one?

How often does your ISP change your IP address, how long is the lease?
Find that time, divide by 2 and set that as the noip2 script timer.

Hi,

I don't have noip2 so I can't walk you through the configuration.

However, from noip's web site http://www.noip.com/support/knowledgeba ... on-ubuntu/ it says the following (for ubuntu), but I think that it will also work for raspbian:

To Configure the Client:
As root again (or with sudo) issue the below command:
/usr/local/bin/noip2 -C (dash capital C, this will create the default config file)

You will then be prompted for your username and password for No-IP, as well as which host names you wish to update. Be careful, one of the questions is “Do you wish to update all hosts”. If answered incorrectly this could effect host names in your account that are pointing at other locations.

Now the client is installed and configured, you just need to launch it. Simply issue this final command to launch the client in the background:

/usr/local/bin/noip2

This should create a file:
/var/lib/noip2/noip2.conf

If you need to change anything else later on you can probably do it by editing the configuration file - noip2.conf

Thank you all for your responses. unfortunately I was not able to reply to your messages I have been very busy.
About noip2, when I try to run the command to reconfigure the host I get the following error:

Code: Select all

sudo usr/local/bin/noip2 -C

Configuration file '/usr/local/etc/no-ip2.conf' is in use by process 3113.
Ending!

What could it be?

[anita2r]

Hi,

It's probably the noip2 process which is already running.

Run your command again - get the process id number - just in-case it's changed from 3113
Then enter lsof | grep 3113 or whatever the id number is
This should show a line with a process path/name
If it shows noip2, then just kill the process
Enter kill 3113 or whatever the id number is

Now try your setup again

When happy with the setup, restart noip2

Guys, I have a much more serious problem. I do not know how it happened, but for the past hour, the server no longer works, I get the message "Error establishin database connection" and I do not know how to fix it. I looked at the apache error log and here is what it says:
