Ubuntu Networking :: Tunneling Through School AP
Mar 14, 2011
I am trying to tunnel through my college's free AP so I can get access to protocols outside of http and https. The school has an in-browser DNS redirect until you log in.The output of "cat /proc/version" on the server OS is "Linux version 2.6.35-27-generic (buildd@palmer) (gcc version 4.4.5 (Ubuntu/Linar o 4.4.4-14ubuntu5) ) #48-Ubuntu SMP Tue Feb 22 20:25:29 UTC 2011" The client OS is Windows 7. What I have done so far is use Proxy Cap to redirect applications to a Putty tunnel connected to the server. Eventually I want to tunnel that SSH connection through my school's firewall, so that I can keep encryption and have a reasonable amount of ease with setup.
I am not particularly educated on the inner workings of the DNS redirecting so I was not sure what to search for. My attempts to connect Firefox over normal http proxies failed and since all ports are blocked besides http and https I didn't attempt any socks or SSH. I have also tried simply hosting the SSH server on http ports with little success. I hope that I can do this without having to purchase a domain, but that's starting to seem like that won't be the case.

I have a local computer (local), and remote computer (remote) behind of remote server (server). Also, I have user access to all of these 3 machines. Now, I want mount some directory, located at remote, to my local mount-point via sshfs. How should I setup my local sshfs and what should be done on server to make this mounting?
I'm stuck with ssh tunneling because the default method for tunneling requires root access while WinSCP somehow could do this with only user access (the tunnel server could be configured there in 'tunnel' panel).

I installed Ubuntu 9.10 onto my laptop, and having wireless issue. I was able to connect to wireless at home, but cannot at school. Then recently, I reformatted by desktop at home, and now I can no longer connect to my own connection. But yet, I'm able to connect to my neighbor. I considered installing ndisgtk package, but then i thought if I'm able to connect to some connections that means I'm not missing windows driver (maybe I'm wrong ).

I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).
However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?

I am trying to map to my schools shares VIA their network.
Normally on windows, I would just say Run and type the network path and it would open a window with the folders.
the path is \KNA11.XX.ON.CA you need to be on our VPN to connect to it, which I am.
How do i access this directory in ubuntu? And even better, make it a permanent shortcut or mountpoint so that i can easily access it later without having to re-mount it.

I've tried the ssh -R ... several times, but can't manage to make it work.I have my home computer (want to SSH into), server (can SSH into), and some computer I want to SSH from.Do I need to install the sshd on the machine I want to SSH into? What are the commands I need to enter to forward from my server to my home computer?

I am using Ubuntu 10.04 LTS - Lucid Lynx(great interface!). But I am experiencing a very weird problem. The wireless internet works just fine at my apartment. But when I am in my school, it just stops working at all. It didn't use to be like that. It used to work in school too few weeks before. But I don't know what happened all of a sudden. I have checked with my school system administrator to know if there has been any change with the network. He said the network has always been the same.

At home, I can easily connect to my home network with ubuntu. But at school, things are differently. The wireless security is tighter, and I need more then just my username and password to connect.
(See attachment for Screenshot)
The last two lines, okay, but I seem to need a certificate, and that MSCHAPv2, Anonimous identity. I don't understand what I need to enter in those fields. I only got a username and password from school and that's all I need for windows. So why does Ubuntu want/need more info?

In windows if I want to do split tunneling, I just uncheck the Use as Default Gateway Box as seen here URL...In Ubuntu, I went to my VPN connection, IPv4 settings, routes..., checked "Use this connection only for resources on its network".And I could no longer ssh into machines on campus.

I am a linux beginner and dont know that much about networks! I have access to a linux VM. The machine is remote and i access via putty. If i can access this machine via SSH and putty, is there any reason why i should not be able to use ssh tunnelling to connect to a vnc server?
I don't know the details of the server and what firewall is set up but i believe that tunnelling uses port forwarding over the ssh connection that is already set up. Where does the port forwarding actually occur? At the actual linux VM or on the router the VM is connected to?

I am trying to setup a version of OzymanDNS but am not quite sure I am understanding part of the instructions found here.My domain/website is hosted with a web hosting company, using their name servers. I have added a sub domain [URL], using an A record to send any requests for [URL] to my home IP address, where I have a server running. Do I need to also add the code below to my server at home which has BIND installed or are the instructions expecting that I have full control of the main name server already?
Code:
tunnel.example.com. IN NS www.example.com.
www.example.com. IN A 123.123.123.123

I have been ssh tunneling, which works great.I can browse the internet by simply tunneling my traffic through my SSH server.the following command: ssh -ND 9999 username at myserver.i cant postlinks.is all I have type, and I can connect to a SOCKS proxy server on localhost:9999.My problem is that I have an application that only supports HTTP proxies.Is there any way I can get it tunneling over the socks proxy?

I am trying to use the ssh reverse tunneling through the command
Code:
ssh -l login -p port <ip address> -R <remote port>:<local Ip>:<local port>
In order to enable some one in the remote host to connect my machine. through the command
Code:
ssh 127.0.0.1:<remote port>
However when I try to execute the first ssh command above I got the warnning
Code:
Warinning: remote port forwarding failed for listen port <remote port>
The problem always happens when the remote host I have tried to connect is my Fedora 14 machine. I can do that when using an Ubuntu as the remote host.

I'm looking for a way to tunnel the internet connection of my Ubuntu VPN server to the remote client.The server is running Ubuntu Server 9.04 64-bit, and has a fully functional installation of Poptop and Squid. Is there a way I can get internet requests from the VPN client to tunnel over the VPN and be connected through Squid? I'd think this would be a iptables thing, but I'm not sure.

I have a server with a /data/ directory, everything in the /data/ folder has "-rwxrw-rw- 1 root root" permissions.all works fine, multiple users are mounting this over a lan and everyone is able to modify files. However I would like to be able to access the /data/music/ directory from the internet.
Is it possible to configure sshfs to only accept logins from a user restricted to reading the /data/music directory, or would it be possible to tunnel nfs over ssh in such a way that everyone on the lan 192.168.0.xxx has unrestricted access to the data directory, but something coming from outside only has read access to the music directory. Although is one were tunneling nfs over ssh, the nfs mount request would appear to come from the server itself. The router is at 192.168.0.1 and the server is at 192.168.0.3.This Seems very much like what I want to do, however I'm having a bit of trouble getting this to work well with other users mounting with full rights over the lan too.

I have been using ubuntu for my college work for some time, and suddenly last week for ubuntu users in a specific Department/building lost the ability to connect to the internet through the school proxy.The problem seems to have effected only our department/building .
What is so annoying is even its the same computer we have internet if we use Windows but no internet for ubuntu.When using ubuntu the DHCP server automatically assigns IP's just as before, and we can reach the Default gateway using ping, but cant reach the proxy server. When we ping the proxy we get a message saying it refuses a connection. When using firefox or chrome we get the same message when we try to browse <proxy server not available>. The network guys says that the only change they did recently is to activate ipv6. But i fail to see how this can become a problem.

I just did an update on an Ubuntu 10.4 LTS machine and it wanted to reboot so I did now I can't even get to the console. I think it's hanging up somewhere on the start up but thanks to the Microsoft like tell you nothing display I don't know for sure or what exactly is hanging up. The only thing the system responds too is ctrl alt del to reboot. Can't even ping it or log in via SSH. I already installed the same updates on this machine but luckily did not reboot it yet. I'm willing to bet whatever package broke the other one will break on this one and if I can figure out where it's breaking I can figure out how to fix it. That means seeing it start up not the blank screen I'm getting. Been meaning to find out about this anyway as the graphics thing annoys me to no end. I prefer to see what services error or fail rather than find out weeks later when I thought my back up service was running and it wasn't or that snort never did run or I'm looking through the logs and discover there's a problem that's been going on for weeks that I never noticed until I went through the logs about something else.
So how do you switch to a detailed start up mode?

I currently have SSH set up on my network and facing outwards so that I can use my private key to authenticate and remotely administrate my server along with the ability to use SSH tunnels when needed to encrypt my traffic. However, I want to be able to give a friend access and use my server as a SSH tunnel, I do not want him to be able to execute any commands or write any files, just to create an SSH tunnel. Although it would not be too much of a large issue if he could write to his own home directory, I just want to ensure that he isn't able to browse around the whole file system and keep it as simple as possible.

I am having difficulty in deciding on a linux laptop for going to school. I will be attending college for a Bachelor in Flight Technology and I need a notebook to take to class with me for notes (So nothing too awkward and heavy). I would prefer one without Windows pre-installed.So far I have considered:-Verix 1656 from zareason, however I am concerned about battery life and screen brightness (I like very dim screens, that which can be obtained with LED backlighting)-Serval Professional from system76, however again I am concerned about battery life (I hear it only gets about 1 hour)-Apple Macbook Pro, however it seems way too expensive for what it offers and might not have the best linux support.
For my battery life concerns, I believe that I could probably get away with running a text editor on the command line without having to boot into a GUI so I can save battery life. I also don't want to get a netbook because I'm likely to do *some* gaming, programming and 3d modeling in my spare time. Are there any other notebooks that I should consider from other places before making my decision? I would try emailing the college, but they are busy with admissions stuff and probably won't care too much seeing as a computer is not a course requirement.
