Hi, I have 8 ethernet cards installed. Is it possible to use eth0-eth6 as the net interface for shorewall and eth1 as the lan network? Thanks. sangprabv sangprabv@gmail.com ------------------------------------------------------------------------------

Hi, I don't have ifcfg-eth1 in my /etc/sysconfig/network-scripts. But when I do ifconfig eth1 I can see output as below. If I do ifconfig eth12 , I don't see anything which i am assume is normal. eth1 Link encap:Ethernet HWaddr 00:24:E8:44:DB:CC BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0

Anyone know how to get statistics on bonded interfaces? I have a system that does not use eth0-3, rather we have bond0, bond1, bond2. The members of each bond are not eth0-3, rather they are eth6, eth7, etc. I didn't see anything in the man page about forcing sar to collect data on specific network interfaces.

Hello Laine: I've revised the configuration and followed all your instructions. I'll try to give you a better explain of my problem. a) I need a bridged (3) configuration, because I have to connect the guests from each others. (via ssh and execute mpi). I've three hosts, each of one has at least a guest. I'll only explain about the configuration of one of them, because the problem

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

Hi All :) I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/\// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the

Hi all. I am currently building a small test cloud based on Eucalyptus 2.0.3 and CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN. KVM is the default in CentOS 6 but I have read also many good things (for example PV guest machines, isolation between Dom0 and DomU) about XEN. Key factors from my opint of view are: - stability (which one runs more smoothly on CentOS?) -

Hi all. I am thinking about installing memcached with replication, I've found http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not want to use client side "replication" (writing to two memcached nodes at the same time) and haven't found other solution. Are there any good, protocol

Hi All. I am trying to install some software. Part of its installation is an invocation of command similar to: # sudo -H -E -u postgres /bin/bash -c /usr/bin/python2.7 /bin/bash: /usr/bin/python2.7: Permission denied >From my perspective: # ls -l /bin/bash /usr/bin/python2.7 -rwxr-xr-x. 1 root root 960376 Jul 8 2015 /bin/bash -rwxr-xr-x. 1 root root 7136 Oct 11 2015 /usr/bin/python2.7

Hi All. I've used syslog-ng for some time. I like it. I have a project in which I need to choose a central logging solution. What are your experiences with rsyslog? Is it more complex to setup than syslog-ng? Or maybe does it have some additional features? I am also thinking about using some gui tools for log parsing and graphing. May be proprietary/paid. Any suggestions? Best regards,

Hi all. I am working for a hosting provider in Poland. We are currently searching for an universal, extensible hardware platform which we would like to use in our server infrastructure. The platform should have: - possibility to install up to 32GB of RAM and at least 4 slots for it; - at least 6 SATA ports; - the possibility to use SAS disks; - at least one 1Gb/s network interface and the

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from

Hi all. I am currently thinking about monitoring a network link (bandwidth, latency, packet drop). I have a centos server which is connected to providers network through a switch. How to test the link? Should I: - use ICMP to ping gateway and collect staistics of time/packet loss/etc. - use software like here: http://www.cyberciti.biz/faq/linux-unix-windows-monitor-outgoing-bandwidth-latency/

Hi All. I have two servers ("master" and "slave") with a replicated gluster volume. Recently I've had a problem with slave and gluster does not work on it now. So I would like to: - stop and remove current volume on master (on slave it is not accessible); - stop gluster software on master (already stopped on slave); - remove gluster software on master and slave (previous

Hi all, First of all I repost this email in shorewall list as there are a lot of firewall experts here that might know what the hell i going on. We have also posted this on the linux bridge list (we needed acceptance first) and leaf list. Very thankful for your understanding. We are experiencing a very strange problem and would need some help. We have a Leaf / Shorewall based box (actually

Hi All.
