I am testing MINE protocol now. I got the basic concept of MINE protocol, but i dont know how to configure MINE protocol by creating a tunnel between two systems.
I did this configuration with linux boxes for GRE protocol.
creating a tunnel for MINE protocol and give me configuration details.?

I am using a lynksys Wireless-N Broadband Router WRT160Nv2 I have installed WICD and removed the gnome network manager WICD tries to validate authentication which fails. then it tries to obtain an ip address which fails. finally it says: CONNECTION FAILED: UNABLE TO GET IP ADDRESS". meanwhile it is showing the wireless network at 100% signal.
last nite tried changing wifi channel, changing to WEP, installed and tried WPASUPPLICANT and WPA_GUI. Unfortunately , nothing worked. The wifi controller was able to assosciate with the network but could not authenticate. I'm wondering if the passphrase that I type in on the computer is somehow being turned into a hexidecimal or something so that it does not match what the router has as the pass phrase.
I installed Ubuntu 10.04 on my new laptop. Everything seems to be running smoothly with the exception of the networking department.My computer is a Toshiba Qosmio X505 with a 8192 Realtek Wireless card built in (I think its called MiniPCI or something)If you need any more information, let me know the terminal commands and I'll get it right away.

I'm trying to set up a secure web tunnel at home I have an Ubuntu box (desktop), a Mac, and a Windows 7 box. I use all of them for different reasons. I want to be able to route traffic from my browser through my Ubuntu box. I have done this before with proxy servers abroad, but I want to do it using ssh and my box at home so I don't have to pay for a service i.e (Secure Tunnel)etc.
I followed the instructions at http://bit.ly/hAnp6u. However, using my Win7 box, after I set the browser part per the instructions, I get no connection from the browser.
Is it possible to chain together multiple SSH tunnel hops in a single `ssh -L` command on the client side? I have two gateways I need to get through in order to access a remote host. For a normal SSH client connection, it's simple enough chain this all together by simply appending the additional SSH connection commands to the first one:Code: ssh gateway.1 ssh gateway.2 ssh remote.host.

I have a headless server, running Fedora 13. I want to make a ssh tunnel to that server from laptop that is also running Fedora 13. Logging into that server over ssh works well, X11 forwarding also works, but I can't establish a ssh tunnel.
At the moment I was trying to connect two small python tcp sample programs, that communicate through port 8000. Running them both on my laptop works well.
What I am trying to do is that I am making two seperate ssh connections to my server, let's say it's address is myserver.com.
1) I make a 'standard' ssh connection to it
Code:
And run the server program
2) I open another terminal window and make the tunnel
Code:
3) I open 3rd terminal window and try to run the client program, that is trying to connect to localhost:8000.
If I understand it correctly, the client should now connect to localhost:8000, ssh would discover that and send that data to myserver.com port 8000. Then the server program on myserver.com is listening on that port and should get that data and send "hello world" string back to the client. Then the client should get that, print it to stdout and exit.
Unfortunatly all what it does is that it just hangs for about ten seconds and then says "connection lost" (timeout?)
I have tried other programs, they also timout.
By passing the -v argument to ssh it outputs:
Code:
When I try to connect the client it prints four more lines:
Code:
So as you see, it says that the connection times out..Also can anybody tell what the "Unspecified GSS failure." means? The possible break in attempt is caused by connecting to the server using the myserver.com address while being in the same local network with the server. If I connect using server's local ip address (ie. 192.168.1.xxx), the message dissappears.

View 1 Replies View RelatedI wanted to create an ssh tunnel but I do not know what commands to run .. my environment is as follows:
LAN Internet Office LAN
Home PC <-> Linux firewall <-> http server..
According to the above what I figure is that I have an internal web server at my job and I need to create a tunnel to access the web server from my PC in my home. I know I can do a port forwarding with the firewall but I don't want to publish this web server to Internet. My home PC and both servers (firewall and web) are ubuntu. My idea is create a ssh tunnel that forward port 8080 on localhost in my home pc, to the firewall (obviously with public ip), and the the firewall forward to port 80 on office web server at my job. Note that the firewall accepts ssh connections to port 22, same for web server...
i need possible direction on setting up a tunnel between 2 different network. The tunnel will be used by devices from the 2 different network to communicate with each other (for eg DevA and DevB).

My school network uses a http proxy to access the internet, but I am dubious about the security, and so I would like to use http inside ssh to keep my data secure. I don't really know where to start on this, so a step-by-step guide, or links to resources, would be helpful.
View 2 Replies View RelatedI'm trying to implement a routing short-cut solution, whose requirement is as following: server1(Linux) sends ip packets(destined to server3) to server2(Linux) via an ip tunnel between them, server2 forwards the ip tunnel's output (the inner ip packets) to server3. Each server has only one NIC and a public ip associated with it. All servers can communicate with each other. I'm sure the ip tunnel between server1 and server2 was configured correctly and worked well. server2's ip_forward was enabled too. On server2, I can capture the traffic on the ip tunnel interface, and they are originated from server1 and destined to server3. The problem is server2 does not forward the ip tunnel's output at all. On server2, I just run "echo 1 > /proc/sys/net/ipv4/ip_forward". Is there anything I missed for enabling ip_forward? Or originally, ip forward can't work on servers with only one NIC, can it?
View 3 Replies View RelatedI have 2 linux servers in different locations. I need to setup a ip tunnel. I follow this steps on both servers:
Server1: ip tunnel add tun0 mode ipip local IP_Server1 remote IP_Server2 dev ethX ip l s tun0 up ip a a 10.10.10.1 peer 10.10.10.2 dev tun0
Server2: ip tunnel add tun0 mode ipip local IP_Server2 remote IP_Server1 dev ethX ip l s tun0 up ip a a 10.10.10.2 peer 10.10.10.1 dev tun0
After creating the tunnel everything is ok, but after a time(maybe some hours), I can't ping the other end of the tunnel (ping to IP_Server1 and IP_Server2 is ok all the time; the connection to internet is very reliable). I have tried "ipip" and "gre" mode, but same result. If I ping from two servers the other end of the tunnel, the connection is again established for some hours and ping is working in both directions.(if I ping only from one side the ping is not working) How can I resolve this issue for no longer having to log on both servers to ping the other end of the tunnel? If I use an crondjob to ping the other end of the tunnel at 2 hours everything is working fine for weeks, but I need other solution.
I've been running a DebLenny system on the network which acts as the local gateway. It has 2 network cards and traffic is directed as follows:
Code:
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT
However, I'd now like to put all the outgoing traffic through a remote system which will further handle the outgoing data (Squid, etc) via the PPPTP device. What would be the most efficient way by which I could achieve this?
I am building up a site-to-site OpenVPN tunnel between two locations. I am setting this up in two CentOS 5.4 boxes each containing two NIC's. I can get the tunnel up and running, and I can ping across the tunnel, however, from the client end of the tunnel I can not ping anything behind the server end of the tunnel. In other words, I can't ping anything on the server's LAN. On both servers, eth0 is the WAN side and eth1 is the LAN side.
OpenVPN server:
eth1 - 10.10.202.2/24
OpenVPN client-server:
eth1 - 192.168.204.1/24
I have IP forwarding enabled in the kernel on both machines.
Code:
[root@vpn01 openvpn]# cat /proc/sys/net/ipv4/ip_forward
[Code]...
I'm sure that the answer is right in front of me, but I can't seem to get it cleared up. I can't hit anything on the 192.168.1.0/24, 192.168.2.0/24, 10.10.4.0 or 10.10.202.0 networks from the client server.
Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it.So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.

So I configured two VPN tunnels for this client. One via fw1 and a backup via fw2. Since the default gateway on the VPN server points to fw1 only the tunnel via fw1 is established. OpenVPN can't establish a tunnel via fw2 because of the gateway and just sits there waiting...
View 1 Replies View RelatedWe are running in to a issue where we don't seem to get our bridging to work as we expected. Meaning passing all traffic from Point A to Point B. As explained below:
[Code]...
This is the original connection. Now we are adding our Linux IP impairment box for IP tables in between Application Server A and Router X so the figure would look as below: Application Server A --> IP Impairment box --> Router X --> router Y --> Application Server B
The issue we are having is When a packets are sent from Server A to Server B they are going through for PING, TCP, UDP, but for BGP the connection is established at a TCP level (SYN, SYN-ACK, ACK), but the BGP OPEN packet does not get through and our BGP relation ship does not come up between Application Server A and B. Application Server A and B are a routers also but there are applications running on those router. BGP is underlying protocol used for Application Server A to be talking with Application Server B and getting routes for each other.
Even with the iptables empty (all rules default ACCEPT) we still can't seem to get these BGP OPEN's through. We see both sides of the application servers sending BGP OPEN's, but the Linux bridge never passes those packets to the other side of the bridge. Tracking the BGP packets, we see the packets at iptables raw PREROUTING and filter FORWARD tables but the packet doesn't get out the other interface.
