Need check script for NO-IP client

[SatWaveDude]

Hi,

I found out that my NO-IP client sometimes does not update/stopped.

Do some of you have a script that checks if the client is still running and if not automatic restart the client?

I need this very badly and have not the Linux skills to do this on my own.

The OS is Debian 6.0.5

Re: Need check script for NO-IP client

Missed updates of ddns may be connected to many reasons and only one of it (but quite rare) is that process is dead.
To troubleshoot your problem we need some clues:
- is the client inadyn, a script or what else ?
- if you have a log of the ddns client, post here.

Re: Need check script for NO-IP client

After a reboot the client is working fine again.

I do not have any log, where do I find it?

This is how I installed the client:

1. cd /usr/local/src
2. wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
3. tar xzf noip-duc-linux.tar.gz
4. dir (than there you see the actual version as dir)
5. cd no-ip-2.1.9-1
6. make
7. make install

To configure do this:

./usr/local/bin/noip2 -C

Then lunch it with:

./usr/local/bin/noip2

Re: Need check script for NO-IP client

I took a look to the package and found out that to put the script in debug mode it must be invoked with the following command:

./usr/local/bin/noip2 -d

You should see errors and messages on stderr but, if you want to log them into a file, the readme states to invoke the startup script with the name of the log file (ex. 'script noip2.log').

A trace log is absolutely necessary to understand what's going on.

Re: Need check script for NO-IP client

I was looking here _http://manpages.ubuntu.com/manpages/lucid/man8/noip2.8.html

Can not find exactly how to create the log file.

First I was thinking that I could use this code:

./usr/local/bin/noip2 -d /usr/local/bin/noip2.log

But that does not work!

Any suggestions?

Ps. how do you stop noip2 client, wich command do I have to use?

service noip2 stop
noip2: unrecognized service

First try with

./usr/local/bin/noip2 -d

If it displays something on the screen then you can redirect it into a file:

./usr/local/bin/noip2 -d > /tmp/noip2.log

Ps. how do you stop noip2 client, wich command do I have to use?

service noip2 stop
noip2: unrecognized service

First check the name of your process:

ps

Then, if it's name is "noip2" (as it should be), use

killall -9 noip2

Again

ps

to check if process has disappeared.

The command PS give results:

15773 pts/1    00:00:00 ps

The command PSTREE give results:

I try killall -9 noip2 and ./usr/local/bin/noip2 -d > /tmp/noip2.log and this is the result on the screen:

# killall -9 noip2
# ./usr/local/bin/noip2 -d > /tmp/noip2.log
# Recovering dead process 17986 shmem slot
> GET http://ip1.dynupdate.no-ip.com/ HTTP/1.0
> User-Agent: Linux-DUC/2.1.9

It seems that the noip2.log in /tmp/ stays empty although the client update is set to 15 minutes and it is runnung for shure.

Re: Need check script for NO-IP client

So now we know for sure that process name is "noip2" and that you can successfully kill it with "killall -9 noip2".

About logging, forget redirection to the file, and simply type "./usr/local/bin/noip2 -d".
You should see all debug info on your screen.

By the way, your log start was ok ...

> GET _http://ip1.dynupdate.no-ip.com HTTP/1.0
> User-Agent: Linux-DUC/2.1.9

but after that you should also see:

< HTTP/1.1 200 OK
< Date: .....
< Server: ....
< Connection: close
< Content-Type: text/html
<
< **.***.***.***
! Our NAT IP address is **.***.***.***
! Last_IP_Addr = **.***.***.***, IP = **.***.***.***

Re: Need check script for NO-IP client

Okay, it does run thats for shure but these I do not see:

< HTTP/1.1 200 OK
< Date: .....
< Server: ....
< Connection: close
< Content-Type: text/html
<
< **.***.***.***
! Our NAT IP address is **.***.***.***
! Last_IP_Addr = **.***.***.***, IP = **.***.***.***

Mabe a De-install & Re-install would help dont you think?
Dont now what I can de else

Re: Need check script for NO-IP client

Yes, the problem is that the program doesn't get any answer from the server, and we have no other clues ...
I wouldn't be stuck with this noip2 and would try another ddns client, such as inadyn, which works very well with no-ip too.

[SatWaveDude]

Re: Need check script for NO-IP client

I'm gonna try NOIP2 once again before I switch to inadyn.
It was working very well in the past on another PC and also Debian OS.

In wich directory do I have to go for best when I'm gonna re-install noip2.
I mean when I give the command apt-get install noip2 in what derectoy do I have to be in?

It doesn't matter, but be sure to be logged as root.

[SatWaveDude]

Re: Need check script for NO-IP client

I'm logged in as root and even type "su" before I install anything.

But in the mean time noip2 seems to register new IP's as it have to

Good, but I wouldn't trust this erratic behavior ...
Also trace debugging seems so muddled ... maybe it was a no-ip server error, but what has failed once, expect it can fail again in the future.

@gianni253

Do you now how I can let auto start noip2 client every time my system reboots?
