Securing communication protocol traffic (SSH tunneling).
2007-12-28 16:51:00 A useful option for secure communication between client/server is to tunnel the communication inside the Secure Shell protocol (SSH). It can be used to tunnel POP3 and SMTP traffic using ssh.-Sure u must have both ssh client and ssh server installed on the two ends.-Create a local ssh tunnel on local machine (ex.port 5110) to the POP3 server's port 110 or SMTP 25 # ssh -f -N -L 5110:localhost:110 user@POP3_server Or even simply binding to a privileged port (110, the POP port) # ssh -L 110:mailhost:110 -l user -N mailhost Same, you can also forward SMTP for outgoing mail (port 25), single ssh line can have multiple -L entries, like this: # ssh -L 110:mailhost:110 -L 25:mailhost:25 -l user -N mailhost-U can still check for port forwarded :Telnet localhost (forwarded port)/You should see the POP3 server's banner information.-Finally you have to configure your mail client to access your mail via POP3 using mail server localhost and desired forwarded port.

Phenomenon called quantum tunneling makes photons exceed light speed
2007-08-17 00:10:00 It seems two clever German scientist claim to have made photons exceed light speed, how they did this was with a phenomenon which is called quantum tunneling. The scientists came across this breakthrough one day when they were conducting an experiment which used a process which used both microwave photons and prisms. Mostly the photons were ...

SSH Reverse Tunneling
2007-06-15 05:13:00 I recently came across a unique networking problem. I had a computer that was behind a NAT firewall which needed to be accessible for Remote Desktop. Actually, it was behind 2 NAT devices, but that’s sort of irrelevant. After spending a lot of time trying to get the correct ports forwarded, I found out that ...

Bypass workplace firewalls: SSH tunneling for dummies
2007-05-08 15:04:00 Franck from Franck's Place posted an excellent how-to some time ago on his blog. Specifically, he provides instructions on how to surf freely at work an bypass idiotic web surfing restrictions. I have quoted Franck's introduction, but will leave you to click the link to view the post in its entirety on Franck's blog.SSH tunneling for dummies"More and more, litigation and regulation is forcing companies to restrict what you can do on an office computer. For some people it's now easier to work from home than the office because of those constraints. The irony is that most people also have handheld devices with none of those constraints anyway. And even without any of those, it's very easy to bypass most protection systems.For example, here is a way to bypass a corporate firewall that prevents you to access certain websites -- not that you should or want to do it. If you follow those steps, you do it at your own risk! But here it is, for educational purposes :)"SSH tunneling for ...

SSTP: Secure Socket Tunneling Protocol and VPN capabilities
2007-04-20 20:10:00 SSTP (Secure Socket Tunneling Protocol) and the VPN capabilities it will offer in future. The article will give a clear understanding of SSTP and compare standard VPN vs SSTP VPN. The article will also cover the advantages of utilizing both SSTP and VPN simultaneously and what the benefits of using SSTP will be. read more
Quantum Tunneling & Solar Fusion
2007-04-11 21:20:00 I like this story because it is an interesting example of how a scientific idea forms. Scientific theories may have gaps, but it is rarely prudent to discard an entire theory. Sometimes a better idea comes along, but sometimes you just learn to think in new ways.Astronomers have long known that "the Sun is a mass of incandescent gas", but until relatively recent times it was not known to be "a gigantic nuclear furnace". Early views of the Sun assumed it was chemically powered--but this could only last for ~1000 years. Gravitational potential energy is sufficient to sustain the Sun for ~30 million years; but once it became apparent that the Solar System was billions of years old, astronomers realized they had a problem.Nuclear fusion of hydrogen into helium was a good solution, but there was one flaw in this theory. Any elementary school student who has played with magnets can tell you that like charges repel and opposite charges attract. The same is true for protons. But if protons ... |
