Installation and Upgrades / NGinx 504 Gateway Timeout error
« on: December 29, 2014, 10:10:37 pm »
Hi:

I have a zentyal community 4.0.5 install running  domain controller and file sharing, openchange, mail and jabber services, for some 500 users (not all connected at the same time). The problem we are having at the moment is that we are experiencing very frequent nginx 504 Gateway time-out errors when attempting to access the managenent console.

The machine running zentyal is a 4 core 4 GB RAM server. top shows samba using 100% of one core fairly often, but the total load average rarely reaches 2. Web access to email works just fine. I am guessing some tuning is required for the perl connection to nginx and/or nginx timeout settings, however, being no expert in any of them, I was wondering if any of you could provide some advice about it.

Thanks,



E.

It turns out that although the change I suggested provides the desired "from" address in the webmail compose window "From" dropdown, it doesn't actually change the from address in the sent email. Worse, the file that does the sending is a binary, so it's not user-editable to fix it.

Did you ever find a solution for this? I currently have the same issue.

Regards,


E.

Did anyone find a solution for this? I am currently having the exam issue, using a just installed zentyal 4.0

Installation and Upgrades / Re: Users synchronization password error.
« on: February 08, 2013, 11:26:30 pm »
I am seeing exactly the same issue here. I had a slave, removed it, added another one and now it complains about wrong credentials. I have copied and pasted them, typed in, have someone else type them in for me, but still it complains that the password is wrong. So basically, I think I bricked LDAP replication. A patch to fix this would be VERY appreciated.

For DNS, I'm pretty sure it is based on Windows Domain infrastructure. THe slave domain controller reads DNS from /var/lib/bind instead of from /etc/bind/. Works here, but only for domains that have been created on Zentyal A (master). Not the other way around.

I understand from your post that If I query the LDAP of port 389 instead of 390 I should get the correct answers (I assume that because somehow the Samba LDAP must have the correct users, given that windows machines on LAN B can authenticate to domain locally managed by Zentyal B with usernames created on Zentyal A). However, I have no idea of the credentials I should use to bind to this LDAP. I am trying with the credentials given under LDAP settings section but I always get this error:

Code: [Select]
additional info: Simple Bind Failed: NT_STATUS_LOGON_FAILURE
Any hints?

Hi:

I have setup 2 zentyal 3.0 servers. Let's call the first one Zentyal A on LAN A and the second one, Zentyal B on LAN B. Zentyal A was set up as a domain controller. Zentyal B was set up as an additional domain controller for the same domain.

Now, on Zentyal A I create users under the users and groups modules and set up my DNS hostnames under the DNS module. Then, if I join a machine from lan B to the domain (which, on that lan, is handled by zentyal B), it autheticates just fine with users created on Zentyal A. Similarly, if I do DNS queries to zentyal B, I get the right answers for hostnames defined on Zentyal A.

But, if I query the LDAP server from Zentyal B, I do not get the results of users and groups created and managed from zentyal A. I would expect that to happen, since I would expect to have some sort of LDAP replication in very much the same way there is a DNS replication.

Is there any way to accomplish this? Thanks.

Installation and Upgrades / Site 2 site VPN is Intermittent
« on: August 03, 2012, 02:53:32 pm »
Hi, all:

I have a site 2 site VPN set up with two zentyal servers on each side.

One of the servers has double WAN interfaces, which are configured for traffic balance and failover. I also set up a gateway rule so that all traffic going from the  LAN to the other site goes through one of the WAN interfaces. When de VPN is up, I can ping machines from the private network of one of the sides to the other one.

The issue is that, several times a day, no traffic seems to get from one LAN to the other; Zentyal dashboard says the VPN is up, but I can't access the other side. Sometimes ping just stops responding, and other times it says that destination is unreachable Then I wait a couple of minutes, and it is back online...

Any hints?

In an attempt to partially workaround this issue, does anybody know where's the template for the named.conf.local file? Specifically, where does it take the zone "." part from?

Thanks,

OK, from what I've been reading, it appears to me Zentyal does not allow to delegate domains to other DNS servers; i tried creating example.com on first server, which works fine. Then i created d1.example.com on the same server, and modified the IP address of its NS record to point to my second zentyal server. On this second server, I set up zentyal to work d1.example.com, which works fine by itself.

The thing is that, when attempting to resolve host.d1.example.com from first server, it fails, instead of referring to the subzone server. I believe this is caused by the way zentyal creates the configuration files for bind. Indeed, on the first server,  named.conf.local has:

zone "d1.example.com" {
        type master;
        allow-transfer { 172.20.18.108; };
        file "/etc/bind/db.d1.example.com";
};
zone "example.com" {
        type master;
        allow-transfer { 172.20.18.108; };
        file "/etc/bind/db.example.com";
};

But it should only have an entry to example.com, and the corresponding db.example.com should include the appropriate NS records for the subdomain.
I short, it seems to me Zentyal's DNS server configuration is not being hierarchic. as DNS by definition is; instead, it is treating all domains as on the same level...

Too bad, I'll have to rollback to pure BIND and DHCP integration :-(

It would be a nice addition, though :-)

Yes, just configure NS records on the desired domain (branch.domain.tld) to point the DNS server in the other office.

I am unsure I follow. What should I set on the zentyal with the parent domain and what on the one with the child domain?

Thanks.

Installation and Upgrades / DNS delegation
« on: July 03, 2012, 03:10:25 pm »
Hi, all:

This is my setup:

My company has 2 offices, one main, one branch. Both offices have a zentyal box and are connected via a Zentyal to Zentyal VPN, so I can ping and connect from any box on one office to any other box on the other one. So far, so good.

Now, what I would like to do is have my main office zentyal be a DNS server for private  / internal domain company.invalid (which I can do easily) and also delegate the domain branch01.company.invalid to the branch zentyal server. The final goal is to have the following:

1. DHCP with Dynamic DNS entries both for main and branch offices, each one provided by its corresponding zentyal box.
2. Be able to resolve by name a host on any office. For example, while being at the branch, be able to resolve server1.company.invalid and while being at the main office, be able to resolve branch01.company.invalid.

So far I have not found any way in the documentation to, first, delegate branch01.company.invalid to another zentyal, and second, tell the delegated / child DNS server to resolve company.invalid via the main office zentyal instead of trying (and failing) to do it via the root servers.

Is it possible to achieve this with zentyal?

Thanks.

Installation and Upgrades / No NAT
« on: June 28, 2012, 09:33:36 pm »
Is it possible to set up zentyal to perform as a gateway *without* performing NAT for the internal network? My current set up includes my ISP router doing NAT, and it seems pointless to  have Zentyal do a second layer fo NATting.

Thanks.

Hi:

Thanks for your reply, I modded the bind template files that zentyal uses and configured my slave dns to pull the zones. It was fairly easy after reading some of the links you provided :-)

Installation and Upgrades / DNS replication
« on: April 12, 2012, 06:58:03 am »
Hi:

I have a zentyal box as authoritative DNS server for my domain. I would like to have a second one, but I don't want to have to enter any DNS changes in the configuration on both boxes. Would it be possible to make the changes in just one of them and have them replicated in the other one? Sort of like LDAP's master-slave replication?

Thanks.

Installation and Upgrades / Several network interfaces as a switch
« on: April 10, 2012, 04:27:12 pm »
Hi:

I have a box with 5 network interfaces. I'd like to set one of them as WAN (no problem, just mark it as external on zentyal). I also want the remaining 4 to behave as a switch for my LAN. Is this possible to achieve with Zentyal? How?

Thanks,
