How to ssh to a remote Linux machine from behind a firewall

Questions 'n' Answers - Technology

Problem Statement

You are behind a firewall (that allows only port 80 or 443), and therefore cannot access a remote Unix machine via ssh (port 22).

Solution

Change the port on which ssh runs on Linux Server:

Run the ssh on the Unix machine on port 443.

In dir: /etc/ssh dir locate following files: ssh_config, sshd_config (do we need to do for both files or only sshd_c0nfig?)

Here uncomment the line: #Port 22 , and change port number to 443.

Now restart ssh: /etc/init.d/sshd restart

Now ssh on the Linux server is running on port 443 (instead of default 22)

Next, ssh using Putty from your desktop

Here:

  • Under Session> Enter Server IP and Port (remember 443, and not 22).
  • If a Proxy Server is in place (its likely if you are behind a firewall) then, under Connection > Proxy enter the Proxy Details. Often people forget this step. If Proxy requires Authentication…

Linux Mint after 3 weeks of use

Mohn Foto

Windows has now been replaced by Linux Mint on both of the family laptops,
I have had literally no problems with the Linux Mint on my Acer Timeline series. Both drivers for ethernet and wlan adapter was preconfigured on install. There has not been any problems with external equipment or installing software.

Both of the laptop is experiencing faster boot ups and general performance increase,and the Linux Mint desktop is really clean and nice for the eyes compared to the newest version of Ubuntu.

I will be testing steam as soon as possible.

If you have an old computer lying around, go linux! It’s fun.

how unzip tar.bz2 in linux

Sayyed Mohsen Zahraee

Open a terminal and type:
tar xvjf filename.tar.bz2
Which will untar it to the current directory. Normally (99% of the time) it will create it’s own subdirectory so you don’t need to worry about that.
Just so you know:
tar – Tape ARchiver
And the options:

  • x – extract
  • v – verbose output (lists all files as they are extracted)
  • j – deal with bzipped file
  • f – read from a file, rather than a tape device

“tar –help” will give you more options and info

‘Avoid the pain of Windows 8’: Try Ubuntu 12.10

Brood Coffee Talk

On October 26, the day that Windows 8 officially launched, a message appeared on the home page of the Canonical website, promoting its Ubuntu 12.10 operating system (OS).

The message was “Avoid the pain of Windows 8.”

Ubuntu is a variation of Linux, the free open-source OS. The basic code is free, and even though software development companies add their own features and then market it, it’s often a free download.

It was first introduced in October 1991, and for most of that time it has been a viable alternative to the other two major OSes, Windows and OS X. Its biggest problem has been that most software components like device drivers aren’t readily available for the OS from device manufacturers. Most distributions handle this by including the more popular ones with the installation software.

From an article on PCWorld.com, “10 Reasons to choose Ubuntu 12.10 over Windows 8”:
