[CentOS-es] KVM networking
Hola, a todos. Instale en CEntOS 5 KVM y funciona perfecto. Tengo 3 MV funcionando muy bien. Ahora lo que necesito es que las 3 sean vistas en mi red lan. Se pueden armar 3 bridges en un dispositivo de red? Como debe ser la configuracion? Ademas, debo poder ingresar a la pc host para hacer mantenimientos y demas. En definitiva: 3 direcciones virtuales + 1 direccion del host, todo visible desde la red externa. Saludos, Gracias! ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

Ahora lo que necesito es que las 3 sean vistas en mi red lan. Se pueden armar 3 bridges en un dispositivo de red? Como debe ser la configuracion? Entiendo que lo que necesitas es un bridge, con tres interfaces virtuales aduntas, más la física. Yo suelo usar un script como éste: #!/bin/sh # numero de mv NUM=$1 USUARIO=miusuario TAPDEV=$(/usr/sbin/tunctl -b -u $USUARIO) /sbin/ifconfig $TAPDEV up # Agregar la interfaz virtual al bridge br0 /usr/sbin/brctl addif br0 $TAPDEV DVD=/home/$USUARIO/imagen-del-DVD-de-instalacion.iso DSK=/home/$USUARIO/imagen-del-disco-virtual.img BYTE=$((33 + $NUM)) /usr/bin/qemu-kvm -hda $DSK -cdrom $DVD \ -no-acpi -m 1000 \ -nographic -daemonize \ -net nic,vlan=0,macaddr=52:54:00:11:22:$BYTE \ -net tap,vlan=0,ifname=$TAPDEV,script=no /sbin/ifconfig $TAPDEV down /usr/sbin/brctl delif br0 $TAPDEV # fin De esta manera cada MV queda acoplada al bridge br0. Variando el argumento numérico del script consigues diferentes números de MAC. El script supone que tú configuras las interfaces de los guests, estáticamente o mediante DHCP. Las diferentes MACs permiten que un DHCP server provea IPs fijos. La configuración del br0 en el host la puedes hacer estáticamente en /etc/sysconfig/network-scripts como se define en las guías de administración. La conf. de br0 (archivo ifcfg-br0) dice TYPE=Bridge y la conf. de la interfaz física que da a tu red local dice BRIDGE=br0 Ademas, debo poder ingresar a la pc host para hacer mantenimientos y demas. En definitiva: 3 direcciones virtuales + 1 direccion del host, todo visible desde la red externa. Este mecanismo debería permitirte todo eso. Quizás alguien tenga un método más amigable...! -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

[CentOS] Logwatch reporting spamassassin messages as unmatched entries
I've recently switched to using spamassassin via a sendmail milter, rather than using procmail to invoke it. This means that I get a number of messages appearing in my maillog, and then being reported by logwatch as unmatched entries. An example of such a messages is: Feb 27 04:33:09 quail sendmail[24780]: p1R4X46P024780[2]: URIBL blacklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_WS_SURBL Contains an URL listed in the WS SURBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_JP_SURBL Contains an URL listed in the JP SURBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_SBL Contains an URL listed in the SBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 0.3 DRUGS_ERECTILE Refers to an erectile drug to \n\t* 3.5 BAYES_99 BODY: Bayesian spam probability is 99 to 100%\n\t* [score: 1.]\n\t* 0.3 DRUG_ED_CAPS BODY: Mentions an E.D. drug\n\t* 1.6 DRUG_ED_GENERIC BODY: Mentions Generic Viagra\n\t* 2.0 RCVD_IN_BL_SPAMCOP_NET RBL: Received via a relay in bl.spamcop.net\n\t* [Blocked - see http://www.spamcop.net/bl.shtml?93.159.243.52]\n\t* 0.9 RCVD_IN_PBL RBL: Received via a relay in Spamhaus PBL\n\t* [93.159.243.52 listed in zen.spamhaus.org]\n\t* 3.0 RCVD_IN_XBL RBL: Received via a ...

[CentOS] cronjob to intiiate checkdisk ?
Dear all, I'm trying to find a way to automate checkdisk every 1 month on a weekend. in other words i want checkdisk to run every saturday morning. i can of course change the default mount/count though that wont let me control WHEN it will happen. so i need your expert opinion with the following if possible: 1. reboot into single user mode 2. start checkdisk for all disks 3. once done, reboot into runlevel 3 i've did a certain script that force checkdisk at night if there's a bad sector using the badblocks command though that's not enough. PS: i was thinking of something of this sort: 1 4 * sat /bin/touch /forcefsck;reboot 1 1 * sun rm /forcefsck Would the above work? for all disks? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I only fsck important machines when I can touch them ... at least via a remote console. If it completes automatically, great. If not, I am there to try to fix it and get the filesystem running. I'm sure others think it is OK to do this automatically, but that is my advise. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yes, as mentioned below, the NIC is given a list of Ethernet MAC addresses. Some [old, cheap] cards had a very small filter list [occassionally just a single entry], so the NIC would have to pass up pretty much any multicast so the next-layer (IP) could decide if it was wanted or not. This shouldn't be an issue today, unless you're using very old or very cheap cards. NIC's work in MAC addresses, not IP. Sort-of. Most NICs know enough about IPv4 multicast to at least help filter unwanted addresses without bothering the CPU. Not quite. NICs have a list of Ethernet multicast MAC addresses that it can be assigned to pass on up the stack. These Ethernet multicast MAC addresses are determined from the IPv6 or IPv4 multicast address, but this is a kernel/driver issue, the NIC still does't have to know anything about IP. Although, there certainly are NICs which know about higher-level protocols (TCP-offload engine), but that's a separate issue. Ethernet _switches_, on the other hand, really need to know enough about IPv4/6 multicast in order to figure out which switch ports it should forward multicast traffic to (otherwise it floods, and we end up with the same traffic flow as broadcast). In IPv4, the switch needs to implement what is commonly called IGMP snooping. IGMP being the IPv4 protocol client devices use for subscribing to multicast groups. In IPv6, IGMP is instead part of ICMPv6 called Multicast Listener Discovery (typically version 2), and the switch feature to look for is called MLD[v2] snooping.

An example of such a messages is:

Assumably you're calling out to spamass-milter. Are you passing any debug (-d)

As to whether to prevent it being logged, or to ignore it in the logs, you
would need to consider whether or not you want it in your logs... it could

Assuming you are getting the time from the ls -l command...
To sort within the ls command (man ls):
ls -lt
To sort after the ls command (man ls):
ls -al --full-time | awk '{print $6 $7 $9}' | sort -r
Not using ls:
To take that input and sort you'd have to do some hashing to translate
the months to a sortable format (like numbers) I think. Alternatively,
you could use the listed date to generate a UTF date via the date command.
