Hi all, i have a xen 4.3 installation and would like to have a bridge bond szenario: *** eth0 eth1 | | bond0 | br0 | vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ] *** With the network script in debian wheezy *** /etc/network/interfaces auto bond0 iface bond0 inet manual slaves eth0 eth1

dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated. I have one nic facing the public internet: vi /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE=em1 BOOTPROTO=none HWADDR=d4:ae:52:c1:28:2b NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet

Hi, I have three linux machines, and I want to let one of them forward packets betwen the other two. The forwarding node has two ethernet cards, connecting the two two machines respectively. However, when I ping between the two end points, the forwarding node can receive the ping requests at its eth0, but it never forwards them to its eth1. So is the reverse direction. The forwarding node is

Good Evening, I am trying to forward packages on an internal device using iptables: /sbin/iptables -A FORWARD -i eth0 -o eth0 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT but the packages are still blocked, e.g.: Feb 6 20:58:28 firewall kernel: DROP-TCP IN=eth0 OUT=eth0 SRC=192.168.100.177 DST=172.28.2.184 LEN=40 TOS=0x00 PREC=0x00 TTL=127 ID=16609 PROTO=TCP SPT=7166 DPT=3590 WINDOW=0

Hi, I have a fedora15 x86_64 host with one fedora15 guest running amavis+spamassassin+postfix and performance is horrible. The host is a quad-core E13240 with 16GB and 3 1TB Seagate ST31000524NS and all partitions are ext4. I've allocated 4 processors and 8GB of RAM to this guest. I really hoped someone could help me identify areas in which performance can be improved at both the guest and

Greetings, all: OS: CentOS 6.4 x86_64 Kernel: 2.6.32-358.14.1 I could use some assistance with setting up pulse to load balance my dns servers. I've configured tcp and udp port 53 with the piranha gui, set up arptable rules on the real servers and added the virtual ip to the bond0 interface on the real servers, but I'm still having no luck in getting things going. A dig against the

Hi all: I have some kvm host(rhel 6.4, 2.6.32-358.0.1.el6.x86_64), I ran several windows guest on it(more than 10 guest on one host and the guest os are win7-32/win7-64/win2k8), but the guest network kept down automatically, lost package. I tried virtio drive and e1000 drive,but it didn't work. However, when I run cmd.exe ping some other subnet ip it worked. The host and guest are connected by

Hi, I''m having issues with policing my incoming traffic by matching packet marks made by iptables. I''ve checked as many sites and guides as I can find, and I seem to be doing the exact same thing as they all are, but there''s still no success. As such, I was wondering if anyone can have a quick look to see if I''ve done anything obviously stupid? Essentially, I

Hi; I sucesyfully ran AD on samba4 software. All required by me functions works properly but when I turn on firewall my enviroment is getting very slow - logon process is 3 times longer then on system with disabled firewall service. Below I pasted my firewall configuration - I based on samba tutorial and aexples and official microsoft web page with needed ports: Have you similar problems after

Hi I am having a weird problem which I cant figure out - so I was hoping someone here could give me a hand. First off the end goal is that a specific server in my network runs an IPSEC connection to another company and I want all other servers to route traffic for the IP on that network through this single server. Server 1 in this example is the server that runs the IPSEC connection. (CentOS

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. My problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"), the traffic can never go from P2.eth1, and all traffic only goes to P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking for the MAC address of 16.119.144.66, although I have specified the route to

Hello All, I am trying to implement OpenVPN on Fedora core Linux 3 with the latest pathces installed. This server is used only as firewall/internet gateway/proxy/VPN server, with kernel 2.6.1-1.27.FC3 and kernel 2.6.1-1.27.FC3 SMP It has two NIC''s eth0 (10.0.0.150) connected to ADSL, eth1 (192.168.3.12) connected to the local network. I use shorewall 2.4 on this machine. I like to test

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the

yes, ip_forward was turned on. iptables is defaulted to ACCEPT policy on all the 3 chains.

I configured tinc as a bridge and everything seems

I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new CentOS 6.3 system. In the olden days, I successfully used the attached iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this doesn't seem to be quite working on the new system. Specifically, while it seems to be routing ok, you cannot connect to anything on the inside net (e.g., with ssh or
