[CentOS-docs] Translation of centos-art.sh script
Hi, Could any of you help me to localize the `centos-art.sh' script into different languages? The infrastructure for doing it is already in place and quite automated. All we need is that you translate strings from English to your own language in an interface like the following: #: trunk/Scripts/Bash/Functions/Render/Svg/svg.sh:54 msgid Saved as msgstr In this interface, `msgid' contains the English message we need to translate and `msgstr` is where you put your translation. The line beginning with # is a comment specifying the location of the English string you are translating. Thank you very much. -- Alain Reguera Delgado alain.regu...@gmail.com ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

Re: [CentOS-virt] wine
In other words, wine is a different program than virt. AFAIK it has its own mailing list, but I would also try the centos.org forums. When you do ask, make sure to include the relevant log files. Or at least a better problem description Just blindly disabling selinux is not a good way to do things. --Original Message-- From: Jan Harasym Sender: centos-virt-boun...@centos.org To: Discussion about the virtualization on CentOS ReplyTo: Discussion about the virtualization on CentOS Subject: Re: [CentOS-virt] wine Sent: Sep 2, 2012 17:23 wine isn't virtualisation, you'll have trouble getting relevant support here.

Eso significa que *ambos deben estar activos, pero sólo 1 de ellos debe resolver las peticiones, mientras que el otro está inactivo, a la espera que el primero falle*. Si lo miramos en un diagrama, podría ser de la siguiente forma (a ver si con esto me explico más): Nube -- *Firewall 1* --- *Firewall 2* -- Red interna El Firewall 1 debería hacer el filtro de tu red, mientras que el firewall 2 debería aceptar todas las conexiones entrantes. Y los roles deberían invertirse para cuando falle el firewall 1. En este caso, debes decidir cómo monitorizar ambos firewall, y es aquí donde entran las categorías que te mencioné anteriormente: filtrar por cantidad de conexiones, por carga en la tarjeta de red, por cantidad de RAM utilizada por el dispositivo, etc. Si preguntas en la lista de CentOS, asumo que tienes 2 computadores, ambos con CentOS, haciendo el trabajo de firewall, cierto? Si este es el caso, puedes revisar los archivos de sistema y generar tranquilamente tu propia aplicación que controle esto, vale decir, que levante el firewall 2 como firewall maestro cuando el firewall 1 caiga, o por X motivo deje de responder peticiones.

[CentOS] NTP server problem behind firewall
Hello! I would like to setup an NTP server for my Windows network using CentOS 6.3 with firewall turned on. As I learned the NTP protocol uses port 123 UDP. I have two NIC cards. One for internal network and one for access internet. Both cards in private address range. The problem is when I am using firewall described below the client cannot access the server. No idea why. Without firewall everything works flawless. So the problem is not in the NTP configuration. No idea why but with disabled firewall the first query gives error but all other query is work. I am using arpwatch to see what is happen on network (new machines and so). Not know is that related to the problem or not. First I had used the system-config-firewall generated firewall (standard firewall with port 123:udp added). No success, client cannot connect. Next I made a script for myself and saved with 'service iptables save' command. The configuration is: eth0 10.0.0.99/24 eth1 10.0.1.10/24 The script for making firewall rules: iptables -P INPUT ACCEPT iptables -F iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -i eth0 -s 10.0.0.0/24 -p udp --dport 123 -j ACCEPT iptables -A INPUT -i eth0 -s 10.0.0.0/24 -p tcp --dport 123 -j ACCEPT iptables -A INPUT -m limit --limit 5/min -j LOG --log-prefix iptables denied: --log-level 7 iptables -A INPUT -j DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT Windows client time server is set to 10.0.0.99. Just for sure I enabled 123 TCP as well even I think that was unnecessary. The rule which related to NTP (123 UDP) increments its packet and byte count with 'iptables -L -n -v' so some connection was made. But no success on sync. Any idea what is wrong?

I am using a more general form of INPUT rule. you can also use tcpdump to capture the traffic between the clients and the ntp server to see what is being blocked. Thanks for your answer. Good idea and I'll do it. # iptables -A OUTPUT -o eth0 -p udp -s client IPs --sport 123 -d NTP Server IP --dport 123 -m state --state NEW -j ACCEPT. I am using iptables -P OUTPUT ACCEPT which allows all OUTPUT traffic on all interface as default rule. So I do not think that I need any more specific rule.

Why? If it's destined for this box, the packet passes downwards in the diagram, to the INPUT chain. If it passes this, any processes waiting for that packet will receive it. The packet destination is my server because NTP server is there so it passes to input box where 123 UDP is enabled. If I read the how-to correctly.

Look for messages regarding the network, drivers or anything else that might give you a clue. If you want more specific help, you need to ask more complete questions. What kind of hardware do you have? What is the network card plugged into? If it's a managed switch, look at it's logs to see if it says anything about the given port. http://www.catb.org/esr/faqs/smart-questions.html#beprecise -- Digimer Papers and Projects: https://alteeve.ca ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
