Before going to vlan topic I have basic question. I have a gateway as 10.209.108.1/22 if I am connecting gateway to cisco 3750 switch port 1 can I use remaining ports to connect via above gateway? I mean suppose I am connecting NIC to port 2 and IP 10.209.111.200 can i ping 10.209.108.1? Is this valid without configuring any vlan or anything on switch?

View 4 Replies View RelatedI am trying to setup a VPN using OpenVPN to allow a secure connection between my smartphone and my LAN. I have been reading an OpenVPN book and some tutorials on how to setup the server side, but I'm stuck at how to create a virtual device. The OpenVPN book says when installing OpenVPN the installer (or aptitude to be more precise) should ask me if it should create a TAP/TUN device. The thing is, it doesn't ask me anything at all. It just installs, that's it.
Most tutorials simply tell me to create a new device in the network/interfaces file. Where is the difference? What should I do now? I like having options, that is one reason I like Linux, but this does confuse me. My second question is about the IP range of the virtual adapter. Should it be in the same range as my LAN, or should I use something entirely different?
how can I create a sub interface and specify a vlan for that sub interface
Reason is that I want to connect to a switch let;s say on vlan 20 but directly to my laptop
I have spent considerable hours searching forums and googling. I have yet to find out what "lm-sensors acpitz-virtual-0 Adapter: Virtual device temp1:" is actually looking at. I have an Abit IP35 motherboard with Ubuntu 9.04 installed.
Here is the output from sensors:
Virtual Device Temp 1 keeps going up to 121 degrees and the computer shuts down. None of the others overheat. Also, my bios does not show my voltages to be set like it lists above. The bios in the motherboard is the latest from Abit.
We have two recently installed centos machines, each running 5.5, and hosting an elastix pabx distro as well as a Virtual PC instance. On both machines, the network adaptor fails completely every week or so. As they are remote machines, the only option we have when this happens is a manual reboot.
I might be barking up the wrong tree here, but the only significant difference on these machines to others we have deployed is the Virtual PC instance. The machines have dual ethernet ports, with one assigned to the virtual PC. When the network failure occurs, it does not effect the virtual machine, which continues along merrily.
My expert colleague does not think so, but can anyone think of any way that our configuration could be causing the problem? If not, does anyone have any ideas on what the problem could be, or where I would start looking for information on the machine to debug the issue?

View 8 Replies View RelatedThere seems to be a lot written about virtual networking but I am not sure what approach to take in my situation. My local subnet has a public block of 128 addresses. I have a virtual host running on my machine. My machine has a static address and I'd need to assign one to the guest. I have edited the guest's interface file and assigned a public address to it's eth0. However the guest cannot ping out and I can't ping in.
By default the virtual machine manager creates a virtual network (virbr0) and assigned a private address range to it. I have tried to create a new virtual network using a subnet of my public range (/31) but the manager says the range must to a minimum of 16 addresses (/4). It doesn't look possible to achieve my aims using the virtual machine manager.
In the past I have used the procedure laid out here:[URL].. which is to manually create a bridge. I am not sure that is relevant for my 9.10. I think I would have to disable the network manager if I were to do that and I am not sure how to do that.
Looking for a test tool where I can fire up any number of ports (TCP and / or UDP) to listen on.
I am currently getting my using nc but its only 1 port at a time (i know I can open up multiple sessions but thats cumbersome), it can't do UDP, and it closes at the end of the session.
A friend has suggested socat but it looks pretty much the same except it can do UDP, but also cumbersome, I have to manually output to a different file per port, etc.
Basically its so I can quickly test firewall and NAT rules.

What I want: multiple virtual hosts with ssl and only 1 ip address: In my example: server = 192.168.227.129
[Code]....
i set up vlan1 in cat2950 switch
#config t
#int vlan 2
#ip address 192.168.1.7
#no shutdown
i then moved all the interface ports (port 1 - port 24) from the default vlan1 to the vlan2, with....
#int f0/1
#switchport mode access
#switchport access vlan2
the problem is that with the above configuration, i connected 3 linux boxes on the switch but non of them could connect with each other.
when i did a ping, it says "destination unreachable"
what am i missing out here, and whats the fix?
i assigned static ip address to these boxes, also there's no router in this network by the way. i dont think i will need one either as all the machines in in the same vlan2.
I'm preparing to "follow" these directions which will make VirtualBox's networking behave like VMWare's "NAT" networking. Of course, these instructions are for a Ubuntu/Debian setup.
I am quite certain that I can write a script that'll do the equivalent steps on my Fedora 11 box -- which is acceptable to me. I would, however, like to know how to splice this stuff into NetworkManager and/or /etc/sysconfig/networking/devices/, to do this the "right" way.
The desired networking behavior:
-VM's get assigned addresses via DHCP on a virtual network
-VM's can talk to each other and to their physical host
-VM traffic out to the 'real world' is NATted

View 3 Replies View RelatedI'm trying to setup a Asterisk box with two NIC's. The idea is that one NIC connects to the LAN on VLAN2 (for internal voice) and the other to the SIP trunk on my ISP's Cisco 1811, configured for VLAN3.
Some info: The Cisco's VLAN1 + 2 are available on my switch. VLAN1 = 10.105.44.x with gateway .254 (the Cisco). VLAN2 = 10.106.45.x with gateway .254 (the Cisco). The Cisco's VLAN3 is available on only a single port on de Cisco, connected to one of de NIC's of the Asterisk box, eth1, with IP 10.106.46.1 and gateway .254 (the Cisco). The other NIC, eth0, is connected to the switch, on a port setup for VLAN2.
So, what I'm trying to achieve: Use eth1 tagged with VLAN3 to connect to the SIP trunk. (I could do this with a static route because my provider has a fixed IP to connect to) Use eth0 for all other traffic.
Here are some config files I've setup so far (I'm stuck on connecting to the SIP provider):
network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
GATEWAY=10.106.45.254

I just have installed FC 10 on a box that I will use as a router/firewall box. On the box I have three interfaces (eth0, eth0.704 (VLAN), and eth1). When the machine boots up, only eth0 and eth1 come up. If I run /etc/init.d/network restart, then eth0.704 will come up. If I add that command to rc.local, then all interfaces come up at boot.
I have the directive ONBOOT=yes in ifcfg-eth0.704. What would cause this vlan interface not to start at boot on the machine?

I'm searching for a small perl script to iterate through the configured eth and vlan interfaces to get their assigned ip address and perform some processing.I'm after something like:

My company hosts five Servers with CentOS 5 installed in a Data Center. The Data Center assigns a VLAN to each customer so that they can organize customers and also count traffic. The VLAN assigned to my company is in the form 62.103.X.X with a subnet mask 255.255.255.240 so the IPs that we can use in our Servers are 13. The first IP in the VLAN (for example 62.103.1.1) is the Gateway and the rest, that are calculated from the subnet mask, are assigned to servers(62.103.1.2 up to 62.103.1.14).
The problem I have is that we have run out of IPs in our VLAN. We have used all IPs and we want some more. The Data Center can assign new IPs but not grow our VLAN IPs by expanding the subnet mask. So they gave us a new VLAN with some IPs (for example 62.104.X.X with a subnet mask 255.255.255.192) They told me that I had to use as gateway the gateway of the first VLAN 62.103.1.1 and assign the new IPs as usual. So I assigned to one of the CentOS 5 servers the IP 62.104.1.2 and set the gateway to 62.103.1.1. Unfortunately this did not work and we could not establish connectivity to the Internet.Is it possible to assign a gateway outside of the IPs that are in the subnet? Could it be a problem with the VLAN setup by the Data Center?
