Networking :: Vpn-vpn Bridge Between Two Networks (1x Debian Server, 1x Cisco RVS4000)
Jan 13, 2011
I've two networks (network 1 in the apartment, network 2 in the basement/server room) I would like to build a vpn connection between the two networks. In networks 1 I have a 24h running PC/Firewall/Debian Server. For network 2 I would like to buy a RVS4000. Is it possible to connect the two objects (Debian and Cisco)?
There was quite a bit of threads about this card, and getting it to work mostly boils down to downloading Ralink's propitiatory driver. The card uses RT2870 chipset, and Ubuntu comes with two drivers that are supposed to support it, neither of which seems to work with WUSB600N. One of the drivers included with Ubuntu detects networks operating on 2.4GHz but fails to connect to them, but does not detect 5GHz networks at all.
I was wondering if anybody knows what is so special with this card that it doesn't work with drivers that are shipped with Ubuntu? The card works nicely with Ralink's driver, but it's a bit annoying to have to recompile it on every kernel update (would be much nicer if it worked with stock drivers).
I am a (somewhat) newbie to Linux (but have an extensive Windows background), and I have just installed Debian Squeeze in an old EeePc 701 4G using the netinst version only with the following packages:
Now I would like to install Debian in my main laptop, but I think it won't be able to connect to any wireless networks during setup and before installing firmware-brcm80211 and wireless-tools (its wireless card is a Broadcom 43224AG). That being, and to avoid connecting the computer directly to the router (it is not easy), I would like to bridge the EeePc's wireless connection to my laptop using a cable. I tried using the instructions found at the Debian Wiki, but I couldn't set it up properly.
My setup is above, I hope it comes out OK on this forum, and someone can understand what its supposed to be! My problem is I am not sure how to get [PC] to be able to see [Internet]. From [Laptop] I can get both networks to work, and have tried using brctl to bridge them, but as soon as I do "ifconfig br0 up" neither network... works anymore (cant ping either router).
I am new in ubuntu and really pleased with performance of ubuntu. Now I am in between a trouble of connecting two network in a switch. I may explain the scenario in detail. I have two Internet connections one connected through LAN (wimax) in to switch having internal DHCP (now we enabled this DHCP to connect our network) and another wireless internet connection connected via USB to a PC, this PC using ubuntu and I am successfully configured ppoe (EVDO), can use this Internet, and this ubuntu possessed PC also connected to Wimax via Network switch. We have 12 PC connected to this switch to share Internet (currently we all using Internet from Wimax through network switch). Still we have a problem of consistency of wimax connection our region. So we decided to connect ppoe (EVDO) in to the same network if Wimax connection is not available. How I connect both in to one network?
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
I have a Ubuntu server with multiple NICs and I'm just thinking about a potential scenario that might come up soon.
Imagine I have a network on floor 1 with an independent cable connection to my Ubuntu server -> switch -> assorted devices, on the subnet 192.168.0.x Now imagine friends upstairs have another independent network with cable -> router -> assorted devices, on subnet 192.168.1.x.
How can I set up my server to provide access for the 1.x subnet to the 0.x and vice versa. Ideally the devices all access internet from their appropriate subnet. I've read something about bridging, is this what I need?
i have 3 servers in 2 dcs as follows; server 1 (dc1 - dmz) --- server 2 (dc1 - internal) --- server 3 (dc2 - internal) Now I have an application in server1 that have to connect to port 44000 in server 3 but dc refuse to open connection saying they do not open connections between dmz and dc2 (i have no say over this).
However I can connect to virtually any port from server1 <-> server2 and also server2 <-> server3. Is it possible to do something like;
server1 <-> server2 <-> server3:44000 using nc to get the app work.
my both linux and windows has 2 network cards each.
basicaly it is vLan cards, each server has 2 network cards. one to main switch and one to local IP.
data will be going like below:
internet ----------------> eth0 --> linux --> eth1 ----------------> Windows.
i have vLans on both servers. And i need cross connection setup. And use linux in bridg mode / cross connection .
actualy i want to use Iptable rules to filter bad packets and forward good packets to windows. i have scripts how to forward packets to windows. but the problem is i dont know how to setup both servers in this topology. and how to make linux as bridge.
All it should be in transparent mode. Not in NAT mode.
Internet <---> Router <---> Debian server <---> Windows PC
I want the server and PC to both have internet access, and I want to be able to forward ports from the router to the server. I know how to configure the server to give the PC internet access, but how would I assign an IP address to the server and give it internet access? I have used a very similar setup a few years ago, but I can't remember how to do this.
I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.
(Fairly new Ubuntu user)I have a Desktop with 2 network cards and a file share.I currently have eth0 configured and working on a network hosing about 30 people.Now I have another 50-60 people connected on a separate network that want to be tied into the same file share. I have configured both eth0 and eth1 for the networks that they are connected on. currently only eth0 works.When I configured eth1 for some reason It shows that it was last used "never".Is there a way to keep these networks separate and share these files from this server?
A server is acting as a router between two networks. If the load increases what happens, to the speed of network? whether the network speed will be reduced or it will sustain the same speed (Ex: 100MBps).
I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet eth1 :192.168.1.222 is connected to the local network eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.
I just installed qemu and want that my VM should have net access too. So for that I installed bridge-utils and used URl....Add both the interface with the second computer, and the interface that leads to the existing network. Do it with this command: # brctl addif br0 eth0 eth1
Here is the setup I have. Two debain (squeeze machines) A1(eth0,192.168.33.1, netmask 255.255.255.0) and B1(eth0,192.168.43.1, netmask 255.255.255.0). They both have 3 nics'. So I am trying to connect to each other with a crossover cable and I have added the routes manually. eg: on machine A1 route added was
I was just wondering if someone could tell me the best method to connect all my hardwares together to achieve better result.HARDWARES.Cable ModemNETGEAR ROUTERNETGEAR FS728TS Smart switchLINUX SERVER WITH 2NICS.I want my dhcp server to serve 3VLAN networks. I need someone to show me how to do this. What do I need to do. keep in mind, I want eth0 to be used for public address only while eth1 for LAN. DHCP will be on eth0, but I need LAN on eth1 to be relayed back to eth0. This is my school project.
I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output: emil@emils:~$ iwconfig lo no wireless extensions.

I am using ubuntu 10.10 and facing problem with cisco VPN connection. VPN connection is getting successful but not able to connect to destination servers.I also tried to add default gw to the the IP which is assigned to my VPN connection but still access to VPN machines not working.
I use VPNC to connect to a Cisco VPN. I am able to connect, but some issues exist when I use SSH. For example, I login through SSH to a computer in the VPN and I execute ls => it works. If I execute ls -la => connection stalls. I think it stalls every time it is supposed to return more content (top, ls /etc).
If I do scp from my end to server => works. If I do scp from server to my end => connection stalls.
I'm trying to install the Cisco VPN client on Ubuntu 11.04, kernel version 2.6.38-8 generic-pae. I need a step by step process since I am an absolute beginner with Ubuntu and this is my first install on the operating system. I have already tried the network manager but connection always fails. I have also tried the website [URL] but this always fails, seems this was made for earlier versions of Ubuntu and earlier kernel versions.
I did a forum search and too much came up that was not the answer I was looking for. I have only Linux devices at work and I was wondering how do Linux Administrators connect to Cisco devices via serial console cable. Cisco recommends 'Hyper Terminal' which was a Windows add-on applications licensed to XP. I think Vista and 7 no longer have the license to use Hyper Terminal. Regardless I don't have any versions of Windows and would like to use a serial cable from Com port 1 to the console port on the device. I can't use SSH since some devices don't support SSH and or I have to do a password recovery.
Is using Cisco AnyConnect for ssl remote access, i loged on on my company vpn.abcd.com , using a username and a password, requested a certificate which was added to Firefox certificates, then installed the AnyConnect client. now i can just start the AnyConnect client to connect without the need to access to my company vpn.abcd.comWhat i want to do is to add a vpn connection to the network manager so its always connected once i powered my computer on, and dont need to start the AnyConnect client to get connected each time.
There were three options Password/SecurID, Certificate(TLS), Certificate(TLS) with TPM.I tried the first one, got a message "Unknown certificate from VPN server "vpn.abcd.com". Do you want to accept it?" , accepted entered my password ---> login failedThe other two options need a certificate files which i dont know how to get, is it the firefoxcertificate, or what ?.
Just wanted to ask a small question... I've set up a VPN connection to my university and i installed and configured everything ok, cause I can connect without any problems...
Now that I'm connected I want my browser to run through the VPN tunnel created by the connection so i can access certain sites that are else inaccessible, but how do i force my browser (I'm using firefox atm) to do that?
When I'm on MAC of Windows OS, as soon as i connect with a VPN, all connection run through them. Fedora seems to ignore the VPN connection and just continues to use my home-network to connect to the internet.
So the basic question is: how do i use the VPN connection.
Iuse FC10, kernel 2.6.27.21-170.2.56.fc10.i686, fully updated system
cisco vpn client 4.8.5 I have no problem to connect it, but got disconnected every minute after I opened a terminal and ssh to company's server. Not sure what's causing the problem. There's no problem to connect to windows.
