To use SSH tunneling with PuTTY, you will need to have a working installation of PuTTY on your computer. In a future article, we will go through how to use Putty to establish a socks proxy as another sort of tunneling. Under this approach, all other traffic would proceed normally, and in order to use the tunnel, you would need to directly connect to the tunnel’s local IP address and port. This article will describe one kind of static SSH tunneling, in which every communication that passes through the tunnel is forwarded to a certain destination host. This is useful for applications like MySQL where remote server access is necessary, but the application’s default means of remote access is less secure than SSH. SSH tunneling, also known as SSH port forwarding, maps a local IP and port to a remotely accessible resource, allowing local applications to make remote connections in a secure manner. Follow these steps to set up an SSH tunnel with PuTTY::Īn SSH Tunnel provides an encrypted connection between a local computer and remote server using the SSH protocol.More suited to temporary setups, such as for wireless VPNs. Since an SSH-based setup entails a fair amount of overhead, it may be Tunnel="2",command="sh /etc/netstart tun2" ssh-rsa. Tunnel="1",command="sh /etc/netstart tun1" ssh-rsa. Tun device 2 from user “john”, if PermitRootLogin is set to The followingĮntry would permit connections on tun(4) device 1 from user “jane” and on # ifconfig tun1 10.1.1.2 10.1.1.1 netmask 255.255.255.252Ĭlient access may be more finely tuned via the /root/.ssh/authorized_keysįile (see below) and the PermitRootLogin server option. To the remote network, at 192.168.1.15, allows it. Remote network 10.0.99.0/24 using a point-to-point connection fromġ0.1.1.1 to 10.1.1.2, provided that the SSH server running on the gateway The following example would connect client network 10.0.50.0/24 with Whether the server supports this, and at what level (layer 2 or 3 traf‐įic). Once you have that new interface up, you'd just have to make it the default route, which is a different question. VPNs are better provided by tools such as ipsecctl(8) and isakmpd(8). Suited to temporary setups, such as for wireless VPNs. ~~ snip ~~ Since a SSH-based setup entails a fair amount of overhead, it may be more Gateway to the remote network, at 192.168.1.15, allows it: Remote network 10.0.99.0/24, provided that the SSH server running on the Whether the server supports this, and at what level (layer 2 or 3 traf. The sshd_config(5) configuration option PermitTunnel controls The tun(4) network pseudo-device, allowing two networks to be joined Ssh contains support for Virtual Private Network (VPN) tunnelling using An ssh based vpn: SSH-BASED VIRTUAL PRIVATE NETWORKS Man ssh gives an example of exactly this. There are some serious bug fixes over the legacy version, like: If you go the proxychains route, please use proxychains-ng. It works similarly to proxychains(-ng) and is also likely in your dist repo: I should also mention another option, which is redsocks. For either Linux or OSX, I highly recommend upgrading to a still-maintained fork: proxychains-ng: īesides working in both Linux and OSX, it is easy to compile, and also has much better support for DNS tunneling. However, the project is effectively abandoned and does not work on OSX. Proxychains is still in most Linux repos and still works on Linux. Since this post is still seeing some upvotes, I thought I'd update it. If they support socks proxies, you don't need to do anything additional to get them to use the above mentioned, ssh tunnel, just enter 127.0.0.1 for the SOCKS proxy server and the for the proxy port. Also keep in mind, that with Firefox, you have to change additional items under about:config to force it to do DNS lookups through the proxy instead of bypassing it.Īs an additional note, on web browsers. However, a few programs will have trouble working with Proxy Chains. Then edit /etc/nf to point to the same port as : socks5 127.0.0.1 įinally start your program that you want proxy-ed like so: proxychains Once it is installed, start your ssh socks proxy like this: ssh -fNTD 127.0.0.1: will start a "SOCKS" proxy listening on. If you only want to tunnel specific programs I would recommend proxychains. The remote server only needs to have Python installed. You can add the -dns argument to have it tunnel your DNS traffic as well. It will tunnel all your TCP traffic automatically for you. To do what you are wanting, I recommend sshuttle.
