VPN vs SSH tunnelling for hotel wifi
I know it’s recommended to use a VPN with a hotel WiFi but if I’m in a hurry and don’t have time to setup my own VPN server would an SSH tunnel (invoked with ssh -D) work just as well to secure my web traffic?

Is telnet secure through SSH tunneling
Firstly sorry, maybe dumb question, but I have one service running on my server which can be operated only by telnet (port 23), but I know that telnet is insecure, so I blocked port 23 in iptables except loopback interface (t… Continue reading Is telnet secure through SSH tunneling
Is the same key used for Authorization and Encryption? (SSH Tunnel)
I am a bit confused on how SSH encryption works.
From reading this question, I see you can use a private key to authenticate with the -i flag.
I also know think that SSH encrypts data using private and public keys.
I … Continue reading Is the same key used for Authorization and Encryption? (SSH Tunnel)
Tunnel ssh over http with custom headers
I’m trying to set up corkscrew to make an SSH tunnel over HTTP, but I need to add custom headers after the “CONNECT” statement and before the ssh tunnel.
Does corkscrew support it? If yes, how can I enable it?
How to obfuscate SSH tunnel Mac?
I am looking to test a DPI (deep packet inspector). I currently have it set up to block SSH connections (which it does successfully).
I have learned that DPI can be bypassed by obfuscating/encrypting the initial handshake (I think, feel f… Continue reading How to obfuscate SSH tunnel Mac?
Are there any feasible ways to block the stunnel utility at the network level?
The stunnel utility written by Michał Trojnara allows, if I understand correctly, to “wrap” non-SSL protocols (such as ssh) in an SSL connection.
For example, imagine that all network ports on a network are blocked except t… Continue reading Are there any feasible ways to block the stunnel utility at the network level?
SSH tunneling shows no response.
I am trying to ssh tunnel into this CTF box and this is the command I am using
ssh -L 2020:127.0.0.1:5901 user@196.168.88.47
and to connect to the 2020 socket I use
ssh -p 2020 root@127.0.0.1
when I do that, it gives m… Continue reading SSH tunneling shows no response.
Harvesting Energy from the Earth with Quantum Tunneling
More energy hits the earth in sunlight every day than humanity could use in about 16,000 years or so, but that hasn’t stopped us from trying to tap into other sources of energy too. One source that shows promise is geothermal, but these methods have been hindered by large startup costs and other engineering challenges. A new way to tap into this energy source has been found however, which relies on capturing the infrared radiation that the Earth continuously gives off rather than digging large holes and using heat exchangers.
This energy is the thermal radiation that virtually everything gives …read more

tunnelling HTTP request through DMZ from a secured area
In my topology I have a secured area where all the servers are. There is also a DMZ with a few reverse proxy servers. I now need to make one of the servers in the secure area open to make HTTP calls to the Internet (to a specific IP addres… Continue reading tunnelling HTTP request through DMZ from a secured area
