I am trying to establish a tunnel from my ubuntu machine 9.10 using miredo package. After installation I wanted to ping an ipv6 address and I get this error:
Address unreachable, destination unreachable
However, when I ping ipv6.google.com I have no problem.
I have a problem with establishing a VPN connection, it's driving me nuts already. No matter what I try, which packages I (re)install, or how many configuration settings i change.. the result is always the same (see syslog at the end of this post). On the same machine, but on a different harddrive, I have installed Windows 7. The VPN connection works without any problems on this system.
I played already with KNetworkManager, NetworkManagerm, KVpn and so on. Further I re-installed each VPN- and network packages multiple times (eg KNetworkManager, NetworkManager, network-manager-pptp, pptp-linux). Further I tested almost every possible VPN configuration (PAP,CHAP,MSCHAP(v2),EAP,MPPE, stateful encryption, no password, BSD compression)... My syslog is as follow:
Code:

One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?

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...
so i start it with ssh -f -R 4096:localhost:22 me@server.com and it comes up and someone can log in at the remote end. how do i close the tunnel from the initiating end ? netstat doesnt seem to identify my end of the tunnel , unless im looking for the wrong thing!
View 1 Replies View RelatedBrowsing via SSH Tunnel very slow When browsing in firefox at work via proxy through ssh on my 8.04 server the speed is near dial up. I have compression enabled, tried restarting ssh, and rebooting the server but it remains so sluggish. At home the connection is quick but the speed is lost in translation once I ssh in. I also tried adding "UseDNS no" to the ssh config but that did not help with the slow login or any other speed issues.

I have a server running Ubuntu Server 10.04 that is a VirtualBox/Samba/SSH server. I have port forwarding set up for ports 22 and 3389 (SSH and RDP) and I want to access the Samba share without opening any other ports. I can connect to it from my internal network, but I want to be able to access it from school. My best guess would be to tunnel the Samba port through SSH, but I don't know how. I will be connecting to it from Ubuntu 10.10 Desktop.

View 1 Replies View RelatedI set up a routed OpenVPN server. Everything works fine. But I'd like to route the DNS queries thru the tunnel too. So I added:
[Code]....
Can't find server name for address 10.8.0.1: Non-existent domain Even thou I have a DNS server set up correctly (on the same server as the VPN) with recursion. I verified that by sending queries form external source, which worked fine. I suspect that the Bind server doesn't listen to the tun0-interface only eth0, but the Bind manual says it should listen to all interfaces by default. The server log shows:
Code:
named[9639]: client 10.8.0.10#3807: RFC 1918 response from Internet for 1.0.8.10.in-addr.arpa
How do I get these DNS queries to resolve thru the tunnel?
I use two Ubuntu machines, one at home and one at work. In order to connect to the machine at work from home I need to connect through a "tunnel server" that controls all the traffic to the machines at work.I am able to connect with ssh to the tunnel server and from the tunnel server ssh my own machine at work. My question is how do I retrieve files form my work machine to the home machine. How do I sync folders between the machines using rsync when the "tunnel server" is in between?
View 3 Replies View RelatedI don't understand the concept of ssh port forwarding and tunneling.I was going to set up a remote desktop (vnc) connection to my grandmother's laptop that we'll give her soon so if something goes wrong i can fix it from here (she lives on the other side of the world). However, i've read using vnc plain over the internet isn't secure, and that i can secure it by running it through an ssh tunnel.That's what i've understood so far. However, from there on i get confused.
I'd have to run both an ssh server AND a vnc server on her laptop? So what i'd have to do is ssh into her computer, and then while logged on on her computer, somehow open a vnc connection back from the remote server to the local computer? Then i'd go back to my local computer and open a port where the vnc connection is waiting? From the concept, it would seem like i should be able to tunnel all the regular network traffic from the local computer to the remote one through ssh?

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.

View 4 Replies View RelatedI'm trying to create EoIP interface on ubuntu so i can create a simple tunnel to my mikrotik router. Is there anyone know how or even done that? If EoIP is not possible, is there any other simple way?
I had already read and thought about doing it with OpenVPN, but when I read the community documentation for OpenVPN on ubuntu 10.10, I fear it won't connect the tunnel to mikrotik OpenVPN server, since OpenVPN on ubuntu uses 2 certificate and 2 key files(as i read on the docs), but mikrotik configuration, i can see only 1 certificate can be applied on. This confuses me and make me decide to use EoIP(but i can't find any tutorial/docs about it). I don't actually need the encryption and security, i just need to create a tunnel for ubuntu and mikrotik.
My friend has a server with 2 ips, 1 primary and 1 secondary/failover. He has given me a shell account and I want to use ssh to route my home http traffic through it like a socks proxy. I connect to his server using the secondary ip like this:
ssh me@secondary_ip -p port -D forwarding_port
It builds a proxy, however it uses the primary ip of the server, not the secondary ip that I logged in with. When using irssi I've bound it to the secondary ip with no problem. If I try to use the -b flag I get the error: cannot bind: Cannot assign requested address.
how I can bind the ssh tunnel to the secondary ip?
I am using 10.04 ubuntu and I have forgotten my password to login to a ssh tunnel. It is not the root password on my computer. Is there any way I can find the password out, change it, or just start over and create a new one? I know it isn't a connection problem because I can't login to ssh from localhost either. I've tried reinstalling ssh too.
View 3 Replies View RelatedI 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.
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).
DevA <-> Linux A <=====================> Linux B <-> 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?
