Installation and Upgrades / connect: Network is unreachable - issue after upgrade of network/firewall mod

« on: April 10, 2017, 10:38:34 pm »

Performed Component updates -  Network/Firewall modules on April 10,2017 which was successful.  After that tried performing rest of updates which were failing.

Checked log  /var/log/zentyal/zentyal.log file to find errors -

2017/04/10 22:20:09 ERROR> install-packages:94 main:: - Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/g/glibc/multiarch-support_2.23-0ubuntu7_amd64.deb  Cannot initiate the connection to us.archive.ubuntu.com:80 (91.189.91.26). - connect (101: Network is unreachable) [IP: 91.189.91.26 80]

Traceroute also gave same error:

#traceroute yahoo.com
traceroute to yahoo.com (98.138.253.109), 30 hops max, 60 byte packets
connect: Network is unreachable

Issue: After component upgrade, routing to external network broke. 

I have performed same upgrade on another system which did not have issue.!

Other modules / redis service does not start - Main process exited, code=killed, status=11/SEGV

« on: March 03, 2017, 08:22:33 pm »

I have Zenytal 5.0 additional server for DNS and Domain controller. 

After system hang, 3 services are not starting after boot - bind9, ntp and redis-server.

I can manually start bind9 and ntp services.  redis-server does not want to come online.

Following from the syslog file:

Mar  3 14:09:08 alndc03 systemd[1]: Started Advanced key-value store.
Mar  3 14:09:08 alndc03 systemd[1]: redis-server.service: Main process exited, code=killed, status=11/SEGV
Mar  3 14:09:08 alndc03 systemd[1]: redis-server.service: Unit entered failed state.
Mar  3 14:09:08 alndc03 systemd[1]: redis-server.service: Failed with result 'signal'.
Mar  3 14:09:08 alndc03 systemd[1]: redis-server.service: Service hold-off time over, scheduling restart.
Mar  3 14:09:08 alndc03 systemd[1]: Stopped Advanced key-value store.
Mar  3 14:09:08 alndc03 systemd[1]: redis-server.service: Start request repeated too quickly.
Mar  3 14:09:08 alndc03 systemd[1]: Failed to start Advanced key-value store.

Any ideas?  Thanks,

Other modules / DNS reverse lookup is not setup - update <domain>/IN denied

« on: February 28, 2017, 07:52:27 pm »

I have Zentyal PDC and 2 Additional DC servers running Development version 5.0 ( upgraded to 5.0.7)

Configuration: - Site A - PDC and ADC ( 2 servers)
                     - Site B - ADC ( 1 server)

DNS is working by name (forward lookup) but reverse lookup by IP is not working.

In syslog, following messages show up:

Mar  1 00:19:57 amddc01 named[1541]: samba_dlz: starting transaction on zone bksd.com
Mar  1 00:19:57 amddc01 named[1541]: client 172.16.16.73#60108: update 'bksd.com/IN' denied
Mar  1 00:19:57 amddc01 named[1541]: samba_dlz: cancelling transaction on zone bksd.com

Do not see any reverse lookup files setup in /etc/bind directory.  I thought its suppose to be automatically setup.  Any suggestion if this needs to be setup manually? 

Using RSAT tools on windows 10 client to manage adding DNS A records  which seems to be working and replicating to all servers correctly.

Installation and Upgrades / [SOLVED] - Zentyal 5.0 server freezing / hanging randomly

« on: February 17, 2017, 08:30:22 pm »

I have Zentyal PDC and 2 Additional DC servers running Development version 5.0 ( upgraded to 5.0.7)

Configuration: - Site A - PDC and ADC ( 2 servers)
                     - Site B - ADC ( 1 server)

We have seen all servers freezing randomly after a while.  No pattern found - specific time, process, memory or cpu issue.

Info for server:

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:        16.04
Codename:       xenial

Possible suspect Samba based on older posts seen.  Did notice samba process slowly eating up memory, specially on PDC. Did not see that it ran out of memory though in top when it hangs.

Have disabled debug logging in smb.conf file which seems to have helped with memory leak.  Also ignoring interfaces not in use as noticed samba trying to look at interfaces periodically.

Any suggestions?

Directory and Authentication / netlogon script in Zentyal 5.0.7

« on: February 16, 2017, 10:28:24 pm »

I have Zentyal PDC and 2 Additional DC servers running Development version 5.0.

Configuration: - Site A - PDC and ADC ( 2 servers)
                     - Site B - ADC ( 1 server)

Testing done in Site B with windows 10 client which has joined domain.
         
Trying to setup a logon script to map shares from external device ( QNAP).

Have done following -

- Stub file in /usr/share/zentyal/stubs/samba/smb.conf.mas
    Added line: logon script = netlogon.bat

- Added script netlogon.bat in /var/lib/samba/sysvol/<domain>/scripts

- Confirmed from client we can see the logon script \\<domain>\sysvol\...
- Run it manually from client and its working.
- tried using RSAT tool on windows client to add logon script path in user profile.
- Setup DNS to ADC ( additional DC) which is local to the windows client.  Have also tried setting DNS to PDC in Site A (remote).

Any ideas why script is not running?
