Installation and Upgrades / SNAT configuration
« on: September 29, 2015, 12:11:36 pm »
Our FAI have routed 5 IP public adress (80.xx.xx.xx) to our Wan IP adress  (200.xx.xx.xx)
200.xx.xx.xx is the Wan interface of zentyal (eth0) where arrive the 5 public adress

We want all communication to  one IP of the range 80.xx.xx.xx be transfered to the same machine with IP  (for exemple)

Port forwarding is not a solutions as the required port is already forwarded.

I try to Configured SNAT diffrent way, but none of them work.

Is the SNAT menu the right way to do it?
How to configure it?

Pour récupérer le backup d'un serveur qui ne démarre plus, j'ai reconstruit un nouveau serveur à partir d'un disque iso.

l'installation de tous les modules c'est bien passé.
Je tente d'abord de restorer un backup à partir du cloud zentyal, mais j'ai systématiquement l'erreur "the following module present in the backup are not installed: haproxy ips webadmin. you need to install them before"

Je ne comprend pas bien, vu que tous les modules zentyal sont installés.

ou alors me suis-je trompé de version de zentyal pourtant les GUI sont identique?

J'ai un gros soucis d'authentification sur mon zentyal 2.2.
En local je ne peux pas aller plus loin que la page de login.
Via un browser j'ai un message d'erreur qui me dis que le serveur n'est pas disponible

mais j'arrive à me connecter un ssh.
Peut on espérer redémarer ce serveur convenablement en re installant certain services et lesquelles?
Mes connaissance informatique étant limité, je ne sais pas par ou commencer

merci de votre aide

In DNS menu I have create a domaine  XXXX.lan with all my IP fixed machines of my lan
System > General > domain : XXXX.lan
Network > DNS : XXXX.lan

Is there something else to config

I have one zentyal 3.4 running fine as Gateway-DHCP-DNS

I am trying to config a second Zentyal (4.0) the same way. In this second zentyal we are using 3NIC.
 - eth0 is WAN
 - eth1 is LAN 
 - eth2 is LAN

DHCP and DNS  is used for LAN on eth1
The gateway and DHCP are running fine. I can access intenet without problem.

But i cant ping an other machine on my local LAN. I got the error message: ping: cannot resolve jobs: Unknown host

any suggestion ?

I arrive at the same conclusion.

Our server memory is too short

Regarding the spam stuff we will move them to another server with a different IP

Thanks everybody for your help

Around 03PM, zentyal high activity reduced to the normal.
I can connect to it in ssh and with a browser normally.
the local GUI also work normally.
Top command no more shows duplicity activity.
Is duplicity the backup service as i understand?
zentyal start its backup at 2am, when the high activity start.
but why duplicity stop working at 3pm whereas zentyal log said ZEntyal incremental backup succeedded at 06:40am

and in any case this can't explain why my server was blacklisted as spam server?

Thanks for your comments

Zentyal is our gateway and MTA.

At 8Am when i arrived zentyal was as usualy bloqued/freeze.
after 2 hours trying to connect with ssh or with abrowser, i got a ssh connection but very slow.
type top commande see attachments
I notice duplicity is taking a lot of memorry, dont know what it is.
GUI cames alive, i can move the mouse, but can't access zentyal interface
ssh connection steel very slow
AS i am alone, i disconnect my zentyal LAN and connect directly my macbook.
like that, I am the only one client of Zentyal.

And unfortunatly Zentyal steel high loaded.
ssh connection is difficult (i have to fait a long time before being connected)
No access by browser connection
Can't lauch zentyal interface localy

One thing is running, i have access to internet

Now i am trying to install jnettop

Thanks Lonniebiz,
I'll check it next time.

Today exploring monitoring curves i fund that zentyal is very busy during the night
This strange high activity start at 2am and stop 8.30am when i reboot the system and it occured every night.

maybe it's a clue
Our server was blacklisted as a spamserver. Can zentyal send massive spam every night? How to check it?

Hi Christian,
Maybe I am not clear.  try to resume.
Every morning it was as the network stop running (no access to internet, clients can't connect each other, no access to mail server) clients loose or can't get  IP adresse.
Zentyal GUI is very slow ou freeze.

After the shutdown/start, clients retrieve an IP adresse can access internet or connect to other clients. All works exept Email server  whereas on the GUI message was indicated as running. Restarting the message service on GUI doesn't fixe the problem.

It was like zarafat prevent dovecot running.
The only solution i fund is killing zarafat and restart dovecot.

While we don't reboot zentyal we don't have mail problem.
But as zarafat is stopped, can it cause the troubles we get in the morning?

Hope to be more clear.

When it appens, zentyal GUI is very slow or freeze.
I have to make a hard switch off.
Turn it on solve the problem but i have to kill zarafat and start dovecot service manually to get my Email running.
I am not sure both problems are linked.

I am not at my office now and will come back thursday and check crontab and zentyal log.
A problem with an equipment on the network steel possible, but how to find it, we have more than 200 clients on our network.

My office use zentyal for few mounth now without troubleshoting.
But from a few weeks, every morning between 7h and 9h, Zentyal stop working. DHCP no more deliver IP adresses, Can't receive or send Email, can't access zentyal by ssh or browser.

Rebooting zentyal fixe the problem until next morning.

I have spent a lot of time reading syslog file without any result, but i don't really know what to look for.
Can somebody help me?
