I understand your concern because is a security flag but I can tell you
that this is only a development environment because I use Windows as a host
but I like to have all related to server in a VM

I am not sure what are you asking|telling me but I was never asked for a
username/password to connect; it only goes ahead and connect but then I
can't do anything like chdir or mkdir or create new files

[CentOS] Enable all permissions for root in Samba ...

As I said in previous messages I have a local virtual machine running
CentOS 7 so I do not need any security. Having that in mind I have
installed Samba and this is how I setup for access the remote server:

[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = CentOS Server
security = user
map to guest = bad user
dns proxy = no

[root]
path = /
browsable =yes
writable = yes
guest ok = yes
read only = no
force user = root
force group = root

I am able to connect as root without password but I can't chdir into a few
directories like for example /var/www. The permissions for such directory
are:

# ls -la /var/www/
total 4
drwxr-xr-x.  4 root   root   31 Aug  4 19:00 .
drwxr-xr-x. 20 root   root 4096 Aug  4 20:02 ..
drwxr-xr-x.  2 root   root6 Jul 18 11:30 cgi-bin
drwxrwsr-x.  2 apache root   22 Jun 30 05:05 html

Why I can't access to /var/html? What I am doing wrong?
Thanks in advance

[CentOS] Can't connect trough SSH to a new fresh CentOS 7 minimal server

I have installed a new CentOS 7 minimal virtual machine in Vmware
Workstation. I have disabled the firewall by running:

*systemctl disable firewalld* => this one for disable it permanently (I
don't need it since it's a VM for development)
*systemctl stop firewalld* => this one for stop the service

I have set SELinux to be permissive.

SSH is up and running as the output from: *service sshd status*

But I can't connect trough SSH, I am missing something?
Thanks in advance

Fedora changed something? I mean I am trying to find the proper image for

[CentOS] SOT: Best strategy for automatize a flow that need user interaction

I am working in a Dockerfile but there is a "secure" MariaDB server script
I need to run which is interactive and I don't know how to deal with this.

Basically this is the flow I have follow on the script at test environment
and is the same I want to achieve in the Dockerfile without user
interaction by just answering as you seen on the flow below:

# /usr/bin/mysql_secure_installation

Enter current password for root (enter for none): [ENTER] // because
there is no password
OK, successfully used password, moving on...

Set root password? [Y/n] n
 ... skipping.

Remove anonymous users? [Y/n] Y
 ... Success!

Disallow root login remotely? [Y/n] n
 ... skipping.

Remove test database and access to it? [Y/n] Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

So I need to write a bash script or something else that could handle this
automatically but has not idea, how would you take care of this?

[CentOS] Where did network setup goes under setup utility in CentOS 7?

In CentOS 6.7 I ran setup command and I could configure network settings
from that "gui" utility at command line. In CentOS 7 I don't know where
this goes or how to enabled. I have installed a few packages:

yum install setuptool -y \
&& yum install system-config-network-tui -y \
&& yum install system-config-firewall* -y \
&& yum install system-config-securitylevel-tui -y \
&& yum install system-config-keyboard -y \
&& yum install ntsysv -y

But I can't see the network settings, see this pic:

Should I install any other package?

What I am asking is if the command above is part of SELinux since I doesn't
use before because it's a VM running on my PC so I not need such security

[CentOS] Apache doesn't display "It works page" under CentOS 7

I have Apache/2.4.6 installed in a minimal CentOS 7 VM. I am trying to
access the default page when Apache is installed by accessing the CentOS IP
as http://192.168.3.130 (is a host only interface) but I got "This webpage
is not available: ERR_CONNECTION_TIMED_OUT" and I can't find why. I have
stopped iptables and then checked:

I have ran those two and still can't access. I have restarted httpd and
iptables services after ran those lines. BTW, what those means? setsebool
is part of SELinux? Or this is new kind of extra security layer on CentOS7?
I am moving from Centos 6.7 to 7 and things change between versions.

[CentOS] Write content to file from Dockerfile and/or any other method

2016-01-28 Thread reynie...@gmail.com

I am building a Dockerfile and I am setting up MariaDB repos as follow:

# Setup MariaDB repos
RUN touch /etc/yum.repos.d/MariaDB.repo

I should write this inside the MariaDB.repo file:
 [mariadb]
 name = MariaDB
 baseurl = http://yum.mariadb.org/5.5/centos6-amd64
 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
 gpgcheck=1

What's the right way to do this? The one below?

echo "[mariadb]" >> "/etc/yum.repos.d/MariaDB.repo"
echo "name = MariaDB" >> "/etc/yum.repos.d/MariaDB.repo"
echo "baseurl = http://yum.mariadb.org/5.5/centos6-amd64; >>

[CentOS] SOT: MariaDB 5.5.x-MariaDB logs are not going to desired .log file

2015-11-30 Thread reynie...@gmail.com

Hi there, I know this is off-topic or semi off-topic but I really need some
help since I am stucked.

I'm trying to redirect MariaDB logs to `/var/log/mysql/*.log` files as
shown below on the `/etc/my.cnf.d/server.cnf` file:

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
[mysqld]
#wait_timeout=28800
#interactive_timeout = 28800
max_allowed_packet=512M

#General Query Log
general_log_file= /var/log/mysql/mysql_query.log
general_log = 1

#Error Log
log_error   = /var/log/mysql/mysql_error.log

#Slow Query Log
slow_query_log  = 1
slow_query_log_file = /var/log/mysql/mysql_slow.log
long_query_time = 2
log-queries-not-using-indexes

collation-server = utf8_general_ci
init-connect='SET NAMES utf8'
character-set-server = utf8

# this is only for embedded server
[embedded]

# This group is only read by MariaDB servers, not by MySQL.
# If you use the same .cnf file for MySQL and MariaDB,
# you can put MariaDB-only options here
[mariadb]

# This group is only read by MariaDB-10.0 servers.
# If you use the same .cnf file for MariaDB of different versions,
# use this group for options that older servers don't understand
[mariadb-5.5]

`mysql_query.log`, `mysql_error.log` and `mysql_slow.log` should go to
`/var/log/mysql/`, right? For some reason, unknow to me, they are not
going. I did run the following query:

MariaDB [(none)]> show variables like '%log%';

And this is the output:

+---+--+

In fact, that's exactly what I did. I have tried to open that 14G .tar.gz
file from mc and it crashes several times so I delete the temporary files
from /tmp and also from /home where originally I copied. I've rebooted the
VM and now the output of df -h looks better:

[CentOS] Cannot open: No space left on device

I have a VBox VM running CentOS 6.7 and I want to extract the content of a
14G tar file. I'm doing as:

*tar -xvf www.tar.gz*


But I am getting a lot of errors like the ones shown below:

html/elclarinweb.dev/wp-content/uploads/2015/03/12-Aura-Ávila-400x320.jpg

tar:
html/elclarinweb.dev/wp-content/uploads/2015/03/Julianne-Moore-11-585x378.jpg:
Cannot open: No space left on device


So, trying to find why the VHDD (Virtual HDD) has left out of space I ran
the following command:

*df -h*
Filesystem Size  Used Avail Use% Mounted on
/dev/mapper/vg_server-lv_root  26G   24G  869M  97% /
tmpfs  2.0G 0  2.0G   0% /dev/shm
/dev/sda1  477M   80M  373M  18% /boot


And then I've tried to find the conflictive files by running:

*du -hsx * | sort -rh | head -10*
du: cannot access `proc/3662/task/3662/fd/4': No such file or directory
du: cannot access `proc/3662/task/3662/fdinfo/4': No such file or directory

Why *df -h* is reporting 24G used? Where the space did go? How I can fix
this?

[CentOS] upstart CentOS vs upstart Ubuntu is there any difference between them?

2015-03-31 Thread reynie...@gmail.com

I'm moving some server configurations from Ubuntu Server 12.04 to CentOS
6.6. Now I'm working on `/etc/init` script that should be handled by
`upstart` at both OS as far as I know. The files on both server are the
same and I mean the same at content level and also at path level and
permissions level, is the exactly copy from Ubuntu to CentOS. I'm having
some issues with upstart at CentOS since scripts doesn't start and I can't
find why (the cause). This is the output from `initctl list` at Ubuntu
server:

# Ubuntu 12.04
root@qa:/etc/init# initctl list
// rest of processes goes here
pdoneVendorBroker start/running, process 854
repToolBroker start/running, process 3705
emailBroker start/running, process 3738
cmeBroker start/running, process 3760
messageBroker start/running, process 3727
shareEventHandler start/running, process 3686
edetailBroker start/running, process 3749
pdoneLoginProctor start/running, process 3716

All the processes has been started at OS boot, that's fine.

This is the output from CentOS server:

# CentOS 6.6
root@staging:/etc/init# initctl list
// rest of processes goes here
pdoneVendorBroker stop/waiting
repToolBroker stop/waiting
emailBroker stop/waiting
cmeBroker stop/waiting
messageBroker stop/waiting
shareEventHandler stop/waiting
edetailBroker stop/waiting
pdoneLoginProctor stop/waiting

None processes has been started after OS boot, and that's wrong. Why? What
I'm missing here? Can any give me some advice?

At CentOS I've tried also to start the process manually by running this:

initctl start messageBroker

And this is the output at console:

messageBroker start/running, process 3587

But if I run the command `initctl list` I didn't see the process started:

initctl list

This is the content for the file `/ etc/init/messageBroker.conf`:

echo $PID  /var/run/messageBroker.pid
end script

post-stop script
rm -f /var/run/messageBroker.pid
end script

Why it's not starting? What is wrong?

Yes I have latest PHP release 5.5.18 not present at CentOS repo so it's not
possible to remove that repo since I'll need in the future for updates
otherwise I'll have a lot of conflicts between versions at CentOS repo and
REMI versions.


 , then I would
 try this:

 yum shell
 remove libevent-last
 install libevent
 run

 Pay particular attention to make sure it isn't removing a bunch of extra
 packages on your system, it should just remove libevent-last and replace
 it with libevent, if it tries to do more then don't accept the changes,
 report back here instead.

 When that's done you should be able to issue a yum update.


Any other workaround that wouldn't be remove the repository?

[CentOS] Right way to install phpMyAdmin through Nginx and PHP-FPM

2014-10-29 Thread reynie...@gmail.com

First I know this is not a list for PHP or Nginx setup or something else
but I'll give it a try and ask here for support I'm running a new server
with PHP 5.5.18 and Nginx 1.6.2 through FPM/FastCGI. The server is working
fine since I have other websites running on it. Now I'm trying to configure
phpMyAdmin and I tried this:

* 1. *Create a file under `/etc/nginx/sites-available/phpMyAdmin with this
content:

server {
   server_name phpmyadmin.dev pma;
   root /usr/share/phpMyAdmin;

   location / {
   index  index.php;
   }

   ## Images and static content is treated different
   location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
   access_logoff;
   expires   360d;
   }

   location ~ /\.ht {
   deny  all;
   }

   location ~ /(libraries|setup/frames|setup/libs) {
   deny all;
   return 404;
   }

   location ~ \.php$ {
   include /etc/nginx/fastcgi_params;
   fastcgi_pass 127.0.0.1:9000;
   fastcgi_index index.php;
   fastcgi_param SCRIPT_FILENAME $root$fastcgi_script_name;
   }

   access_log /var/log/nginx/phpmyadmin/access.log;
   error_log /var/log/nginx/phpmyadmin/error.log;
}
 But any time I restart Nginx service I got this error:

 nginx: [emerg] unknown root variable
nginx: configuration file /etc/nginx/nginx.conf test failed

* 2. *Create a symbolic link in `/var/www/html` to the route where
phpMyAdmin was installed `/usr/share/phpMyAdmin` by running `ln -s
/usr/share/phpMyAdmin/ /var/www/html` that way Nginx start fine but when I
go to `http://devserver/phpMyAdmin` I got `Access denied.`

What I'm doing wrong? What is the right way to configure the server in
order to serve phpMyAdmin as any other site?

 By looking at fdisk output pasted in your first mail, I don't see more than
 2 partition in your first disk - /dev/sda .
 The first partition is -  /dev/sda1 - is allocated for /boot  and
 second partition is -  /dev/sda2 - for your PV/VG/LV where root resided.
 However, the above output indicates you had 2 PVs , which is contradicting
 with the information you have shared so far.

 I assume that, you have added an additional disk , then extended the VG,
 but later removed ? OR  tried another vgcreate ( afaik, lvm shouldn't allow
 this but a wild guess ) on actual PV - /dev/sda2 ?


You're right in some moment I added a new disk and try to extend the VG and
yes once again I removed by trying to do the same from Gparted Live CD and
I messed all, this is what I'm trying to fix if it's possible so what
procedure I should follow having this extra info? (apologies perhaps I
should say this from the begining)

 still have the additional disk?  The best thing to do would be to put
 it back, make a partition on it, and then re-create the missing PV.
 I'll assume that the new partition is /dev/sdb1.  Adjust all references

 (I've broken that up into multiple lines to avoid word wrap problems.)

 You should then be able to run pvs and lvs successfully. To properly
 remove this PV from the LVM structure, run

lvreduce --extents -8 /dev/vg_devserver/lv_root
vgreduce vg_devserver /dev/sdb1
pvremove /dev/sdb1

 That lvreduce will get rid of the 32MB that were allocated on that
 added PV.  You will probably get a warning about possible data loss
 and will have to confirm.  The vgreduce and pvremove should then
 proceed without any issues.

Yes, that is all and yes I made the changes from a Gparted LiveCD :-\



 If necessary I could edit the backup file that you have now and clean
 out all reference to the missing PV, but I'd rather not do that if there
 is a safer way.


Ok, I attached the file here but also will be nice to extend the LVM so it

Yes, before the latest change I reboot several times and system always pass

 Are you seeing any messages prior to the kernel panic?  If not, reboot and
 press TAB to see the GRUB menu.  Press a to get to the kernel parameters
 and then remove the parameters rhgb and quiet.  Then you will get to
 see
 what leads to the panic.


I leave you the printscreen on the image link, anyway is a VM the only

[CentOS] No free sectors available while try to extend logical volumen in a virtual machine running CentOS 6.5

I'm trying to extend a logical volume and I'm doing as follow:

1- Run `fdisk -l` command and this is the output:

2- Run `fdisk /dev/sda`and print partition using `p`:

I also check the free available space using vgdisplay and watching the Free
PE / Size part near the end and seems like I've free space available (Free
PE / Size 7670 / 29.96 GiB) so I tried to extend the LV by using the
command:lvextend -L+29G /dev/vg_devserver/lv_root but I got some errors and
don't know where to go from here. The first error I see at console is
this /dev/root:

VG vg_devserver while PVs are missing. Consider vgreduce --removemissing.

Then following the suggestion from the previous command results I run this
other command vgreduce --removemissing vg_devserver but again got this
error: WARNING: Partial LV lv_root needs to be repaired or removed. There
are still partial LVs in VG vg_devserver. To remove them unconditionally
use: vgreduce --removemissing --force. Proceeding to remove empty missing
PVs. so I change the command to the one suggested but once again another
message Removing partial LV lv_root. Logical volume vg_devserver/lv_root
contains a filesystem in use. so at this point I don't know what else to
do,can any give me some ideas or help?

Don't kill me if is something basic I'm not a Linux Admin or a Linux
Advanced User just a developer trying to setup their development
environment. How I can get this done? What I'm doing wrong?

I'm following [this][1] guide because my filesytem is Ext4. Also [this][2]

Re: [CentOS] No free sectors available while try to extend logical volumen in a virtual machine running CentOS 6.5

Hi SilverTip nice answer and very helpful, I'll try to get some more help
here since as I said in the main post I'm not an expert on Linux or a
Administrator I'm just a developer trying to setup a development enviroment
so ...

It's telling you the truth.
Sounds like you want another Logical Volume (LV) not partition.

You're right, what I need is a new LV but how I do that?

Sounds like you destroyed one or more of your LVs through all this.

Probable and I'm pretty sure I do it :-(

Please read the following documentation before forging further ahead.
And you might spin up a VM or live CD to experiment with LVM operations
before going any further as well.
- speaks about extents [0]
- read the entire Chapter 2 on LVM [1] as it applies to your scenario (ex:
snapshots probably don't)
- dated/older, but it may prove helpful [2]

Fine, I read it but know doubts persist on my mind. First, I'm running OS
in a Vmware Workstation VM and I'll not like to loose every I have there
since then I'll need to reconfigure all from scratch but if there is not
another option to save my mess the we should go through it. Now I'm almost
sure what I need here is a Linear Volumes configuration why? Well because
my VM disks have 30GB in first and now I resize it to 80GB and that's the
space I want to see in my Linux and can't get it. In order to get it
working again, what steps I should follow? That's my concern and what I've
clear at all

Thanks

Uppsss I think this goes more and more advanced all the time but here I go
 more doubts

 If I were in your position, I think I would:
 * Create a new, 80GB disk using VMWare


Not problem at all


 * Partition that disk into your /boot and LVM partitions


How I do that out of the box? I mean should I mount that disk in the VM and
partition from there, right?


 * pvcreate
 * vgcreate


Ok, create physical volume and volume group


 * lvcreate the disk structure you want in your new disk, making sure all
 LVs are at least a little bigger than the old ones.


Here I get lost, what structure should I create here? I only have one LV
lv_root you mean create the same and of course bigger than the old one,
right?


 * use dd to copy disks from old drives to corresponding old drives


And here I declare myself complete lost, this is the first time I see this
command and don't know how to use it


 * use resize2fs to expand your file system to the full size of each of the
 LVs you created.
 * detach old virtual disk from your VM
 * reboot, and see if you succeeded

 If I forgot something here, hopefully someone else will chime in.  The
 idea is to dump your corrupted LVM structure without loosing its content.

 Those I/O errors are alarming.  They suggest that you have a disk that is

[CentOS] CentOS7 Minimal installation on Vmware missing network interface

Hi there, I'm playing with CentOS 7 (don't know if it's recommended at all
have this one as a development server as maybe is not stable enough yet)
and I installed it on a Vmware VM with two network interfaces: one as a
bridged connected directly to the physical network and replicating the
network state and the second one as a host only interface (the one I use to
manage the VM) so after I got the CentOS installed I can see the first
interface but not the second one and I don't know how to enable it. If I
run the command ifconfig -a this is what I see:

eno1628: flags=4163UP,BROADCAST,RUNNING,MULTICAST  mtu 1500

What I need to do in order to enable the other interface? Also how I change
the name eno1628 to eth0-internet without get down my server?

 This is something of a loaded question and also quite dependent on what

It's not critical, just a development server I'll like to configure in
order to start learn a bit CentOS 7 (I'm not a System Administrator expert
but a developer)


 If 'ifconfig -a' doesn't see it, the kernel probably doesn't, either. Do
 you see it in lspci or dmidecode? If not, I would look at the hypervisor
 for a problem.


As I said above I'm not a expert but I did man dmidecode since lspci
isn't available and I can't find a TYPE for see network interfaces also I
do not know if the output is related to motherboard (the one I have) or is
related to emulated board (if this has sense), so what command should I run
to give you proper info?



 Yes you can do it without rebooting, but it still requires taking the
 network down.

 I wrote this a while ago:

 https://alteeve.ca/w/Changing_Ethernet_Device_Names_in_EL7_and_Fedora_15%2B

 It probably needs to be updated/cleaned up, but it should be good enough
 to help you.


I'll take a look in a few minutes after system updates complete

Ok, since my default route is bad,

# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse
Iface
0.0.0.0 192.168.3.1 0.0.0.0 UG1024   00
eno33555200

192.168.3.0 0.0.0.0 255.255.255.0   U 0  00
eno33555200

I tried this two ways:

1) */etc/sysconfig/network*
 Add line GATEWAY=192.168.1.1

Restart the newtork service:
# service network restart
Restarting network (via systemctl):[  OK  ]

# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse
Iface
0.0.0.0 192.168.3.1 0.0.0.0 UG1024   00

eno16780032
192.168.3.0 0.0.0.0 255.255.255.0   U 0  00
eno33555200

Still no changes

2) */etc/sysconfig/network-scripts/ifcfg-eno1628*
 Add line GATEWAY=192.168.1.1

Restart the newtork service:
# service network restart
Restarting network (via systemctl):[  OK  ]

# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse
Iface
0.0.0.0 192.168.3.1 0.0.0.0 UG1024   00

192.168.1.0 0.0.0.0 255.255.255.0   U 0  00

192.168.3.0 0.0.0.0 255.255.255.0   U 0  00

Still no changes

What I'm doing wrong? Every time I do a network change/configuration I need
to restart the complete OS in order changes to take effect, why?

Re: [CentOS] Can't reach Internet

Ok, now I've fixed the Internet connection by running this command: ip
route replace default via 192.168.1.1 but now I have two default routes:

# ip route show
default via 192.168.1.1 dev eno16780032
default via 192.168.3.1 dev eno33555200  proto static  metric 1024
192.168.1.0/24 dev eno16780032  proto kernel  scope link  src 192.168.1.112
192.168.3.0/24 dev eno33555200  proto kernel  scope link  src 192.168.3.131

Is that right? How do I remove the second one? (default via 192.168.3.1 dev
eno33555200  proto static  metric 1024)

 alternately, is the 192.168.3.x interface being configured by DHCP?
 perhaps its DHCP server is handing out that gateway.


No, it's handled static:

Gracias, ya me lo estoy descargando para probarlo en una VM, por otro lado,
una pregunta extra, tengo entendido que oficialmente Zimbra Comunnity no

Alguna guia de migracion de buzones de correo y configuraciones de una

 Gracias por contestar. Si bueno lo que quería era administrarlo via web

 Me pondré a implementar haber cual se adapta mejor.

  Iptables es muy bueno, va integrado en el kernel de linux y todo esto

  que se administre via web y venga implementado, he encontrado las
  siguientes:
 
  smoothwall, clearos, ipcop, pfsense, ebox
 
  Yo me decantaría por pfsense(freeBSD), ya que la pila TCP/IP la maneja
  muy bien. También me ha gustado mucho clearOS.
 
  Alguien ha probado alguno y me puede aconsejar??
 
  Sería para proteger puertos, enrutar tráfico, realizar vpn, posibles
  problemas de tráfico, estadísticas...etc.
 
  Saludos.
  Holas...
 
  IPTABLES... sí o sí lo necesitas, ya que es el módulo que se carga en el
  kernel de linux que maneja todo lo que es control de rutas, filtrado etc.
  Lo que vos querés es una interfaz web para manejar todo el sistema de
  reglas...
 
  Si tenés la distro común instalado, posiblemente ya tengas a IPTABLES
  instalado; y para manejarlo vía web, por ahí solo necesitas tener
  instalado webmin. Te logeás en el webmin y hacés lo que vos querés
  con firewall.
 
  Hay otros administradores de reglas gráficos como el firestarter...
  pero son más limitados... y este último no es web.
 
  Otra forma de administrar el fw es con shorewall
 
  Otra más, y si querés practicar cosas... sería instalar por ej.
  Proxmox; es un sistema autónomo basado en linux, y con todo lo que
  necesitas para virtualización como KVM+qemu, OpenVZ,...
 
  Y en una de sus máquinas virtuales, te instalás un fw... y lo manejás
  vía web desde otra de las virtuales... ufff... podés hacer muchas
  cosas... pero claro ... e sotra cosa más compleja.
 
  Otra distro chica especial para eso era (o es...) brazilFW o algo así;
  es lo que antes era coyote.
 
  Las que vos nombras solo conozco a la primera, pero no la he usado.
 
  Bueno espero que ayude en algo.

 El hecho de que en /etc/resolv.conf tengas la entrada

 nameserver 10.13.0.3

 probablemente este reenviando la peticion de DNS al servidor de DNS que
 tienes en la maquina host donde instalaste VMware.

 Si quitas esa linea podrás mandar la resolución local, pero solo
 resolveras localdomain. El dominio soltiven.com no lo tienes en tu DNS
 local. Por eso cuando pides que resuelva, reenvia la peticion al servidor
 de DNS 10.13.0.3

 Si quieres que rep-mgr.soltiven.com te resuelva a rep-mgr.localdomain,
 tendrás que añadir una entrada en /etc/hosts o en el servidor de DNS local.

VM dentro de Vmware Workstation y cada una de ellas tiene dos interfaces de
red: eth0 (que tiene la misma subred que mi tarjeta fisica, la de mi
compturadora o sea la 10.13.13.x) y eth1 (que es un NAT para que las VM se
vean entre ellas cuya subred es 192.168.1.x). La VM que finge como DNS
tiene IP 192.168.1.2 y este es el named.conf:

options {
listen-on port 53 { 192.168.1.2; };
listen-on-v6 port 53 { ::1; };
directory   /var/named;
dump-file   /var/named/data/cache_dump.db;
statistics-file /var/named/data/named_stats.txt;
memstatistics-file /var/named/data/named_mem_stats.txt;
recursion yes;
};

logging {
channel default_debug {
file data/named.run;
severity dynamic;
};
};

zone . IN {
type hint;
file named.ca;
};

zone local.domain.com {
type master;
file /var/named/local.domain.com.hosts;
};

Y el fichero local.domain.com.hosts contiene lo siguiente:

$ttl 38400
local.domain.com.   IN  SOA ns.local.domain.com.
ad...@local.domain.com. (
1324940087
10800
3600
604800
38400 )
local.domain.com.   IN  NS  ns.local.domain.com.
rep-mgr.local.domain .com.   IN  A   192.168.1.30
squid.local.domain .com. IN  A   192.168.1.10
ns.local.domain .com.IN  A   192.168.1.2
bacula.local.domain .com.IN  CNAME   rep-mgr

Todo esta correctamente configurado porque el DNS (Bind) inicia
correctamente. Ahora bien el tema esta en que si desde la VM
rep-mgr.local.domain.com hago un

[root@rep-mgr bacula]# dig rep-mgr.soltiven.com

;  DiG 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.1  rep-mgr.soltiven.com

Me responden unos servidores a.gtld-servers.net. nstld.verisign-grs.com.
que no se de donde salen. El fichero /etc/hosts de ese servidor tiene esto:
127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.1.2 ns.local.domain.com

Y el fichero /etc/resolv.conf
domain local.domain.com
search  local.domain.com
nameserver 192.168.1.2
nameserver 10.13.0.3

Donde esta el error? Alguna ayuda?
Saludos y gracias por adelantado

Re: [CentOS-es] Error con conexion SSH mediante Putty y dsd Windows

Bueno el problema va un poco mas alla puesto que he intentado conectarme
desde pgAdmin al servidor de PostgreSQL que tengo en una VM e igual me
cierra la conexion pasado 5 segundos, alguna idea de que puede estar
sucediendo?

 Eso me ha pasado cuando tengo algun firewall (no windows) habilitado.
 Usualmente dan falsos positivos y los bloquea

Re: [CentOS-es] Error con conexion SSH mediante Putty y dsd Windows

El SELinux esta activo mas no creo que sea ese el problema porque yo puedo
conectarme por SSH solo que al cabo de unos 10 seg o un poco mas como
maximo se me cae la conexion al servidor, el SSH por supuesto que esta
activo :) y en el iptables el puerto 22 esta abierto aceptando conexiones

 Tienes habilitado Selinux?
 Esta el servicio ssh activo?
 El Firewall que trae Cent0S, esta activo?

 Hay opciones del servidor o del cliente que hacen un timeout
