Hi All, I am working on a mystery. I am using openvpn-2.1_beta7-gui-1.0.3-install on all the computers in question. All computers are running XP-Pro-SP2.

I use it to call five facilities: remote aa.bb.cc.dd port 5030 proto udp dev tap ifconfig 192.168.240.30 255.255.255.0 secret

Hello, I want my CentOS 6.5 computer to have a static IP. Currently I get the IP I want because I have my router assign it on the basis of mac address. I placed the following file as: /etc/sysconfig/networking-scripts/eth0 DEVICE="eth0" BOOTPROTO=static HWADDR=00:1F:D0:9E:AE:67 ONBOOT=yes TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes NETMASK=255.255.255.0 IPADDR=192.168.0.99

Hello, I'm trying to set up IP aliases within a QEMU/KVM guest on CentOS 5.5 x86_64, going through a bridged virtualized interface.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A few months back, I tried to use the network scripts to provision an IPv6 range like can be done with IPv4. I was using CentOS 5.2 at the time and was informed that 5.2 was broken in this regard. I have upgraded to CentOS 5.3 now and I am trying to get IPv6 to provision an entire range of IPs, but I am still getting the old behavior and no IPs are

Dear Friends I have 2 netcards (eth0 to Internet and eth1 to internal network) in CENTOS 4.2, bit when I boot system the up eth0 and et1i [OK].

My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient. I'd like to figure out what software is rewriting this file and why. man 5

Hello guys, I have two ISP's connected to my router. One via eth2, second one via ADSL modem, with ppoe doing on my Centos 5 . The problem I have is, that when ADSL fails , interface ppp0 is removed. This also removes my static routes configured for this interface. I do not want that, as I have load balancing configured and default route is removed when ppp0 interface disapears. This is my

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

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.

Hi All, I have 2 NICS in this system. CentOS 6.4 eth0 is the virtual IP from PFSense mapping connected to the router, works fine. eth1 is a second NIC that I have assigned a private IP to and connected it to a switch on the private network. I have many other private devices, so I know this setup works. When I connect the cable to the switch and bring up eth1 the system basically stops taking

Hi, I'm trying to configure a network bridge over a bonding without any success. Here is my configuration: ifcfg-eth0: DEVICE=eth0 HWADDR=00:1E:C9:E8:3F:E5 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-eth1: DEVICE=eth1 HWADDR=00:1E:C9:E8:3F:E7 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-bond0: DEVICE=bond0 ONBOOT=yes BRIDGE=br0 USERCTL=no ifcfg-bridge0: DEVICE=br0

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue
