ssh and forwarding.

hack3rcon · 12-04-2018, 09:14 AM

Hello.
I want to forward all my local connection to a remote server. I used below ssh:

Code:

ssh user@server -L 9080:localhost:9080 -N

And set my browser proxy to "localhost:9080" but I can't browse any website.

How can I solve it?

Thank you.

Have you searched how to use ssh as a HTTP proxy?

https://www.linuxjournal.com/content...ate-http-proxy

Although from your other networking thread that may not be what you really want.

Thank you. If it is a device that connected to the internet then can it work? For example, a router that has ssh service and ssh to it from Linux.

Not sure exactly what you want to accomplish.

The device that I ssh to it, is Cisco and have below open ports:

Code:

PORT      STATE  SERVICE
22/tcp    open   ssh
113/tcp   closed ident
443/tcp   open   https
2000/tcp  open   cisco-sccp
4443/tcp  open   pharos
5060/tcp  open   sip
50300/tcp closed unknown
50389/tcp closed unknown

I did "ssh -D 4443 user@IP" and set my browser proxy on localhost, port 12345 and SOCKS v5 but browser tells me "Unable to connect" and ssh say:

Code:

channel 3: open failed: resource shortage: 
channel 3: open failed: resource shortage: 
channel 3: open failed: resource shortage:

A socks proxy is similar to a VPN tunnel. From the error message it does not appear your Cisco device is capable of being a proxy.

It is a Cisco ASA and connected to the internet:

Code:

> ping google.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 216.58.209.238, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/6/10 ms

I can use "Cisco AnyConnect" for VPN but is ssh impossible?

I don't know but at the moment I would say not.

check out this link: https://ma.ttias.be/socks-proxy-linu...ntent-filters/

From link above it says:
Once that's set up, you can configure your browser to connect to the local TCP port that the SSH client has exposed, which will then transport the data through the remote SSH server.

But, it is not a Linux server, it is a device.
