How to change “-bash-*”?

Asim Zeeshan — Wed, 23 Jun 2010 15:07:47 +0000

If you are seeing this in your bash (SSH), It makes it tough to navigate through SSH since it doesn’t give you much information.

-bash-3.2#

To fix that, you can simply type this in your SSH when logged in:

PS1="[\u@\h \W]\$ "

Configuring SSH on Ubuntu 8.10

Asim Zeeshan — Wed, 07 Jan 2009 21:22:58 +0000

The first issue that I had after installing Ubuntu 8.10 was that I could not connect to SSH on it because SSH server is not installed on Ubuntu 8.10 and it never asked me if I wanted to make a selection of what software packages I need to have installed. I guess thats why they are making a less then 25 min install promise.

Here’s how you can enable / configure / install SSH on your Ubuntu 8.10
Open a terminal window by selecting the Applications menu and selecting Terminal from the Accessories menu. In the terminal window enter the following command and press enter to execute it

sudo apt-get install openssh-server

It will automatically download and install the SSH serve and configure it to run on port 22 (default port).

I will write another article to explain how you can change the port or enable / disable the SSH server.

To create a tar from a directory using SSH on Linux punch in the following command

tar -vcf backup.tar mystuff/

Where “mystuff” is a directory and backup.tar is the target compressed file.
You can also create a file called archive.tar of all the files and subdirectories in the current directory with the following command

tar -vcf backup.tar *

Note: “v” flag is for verbose mode.
