How to run commands on a remote machine using ssh(no interactive shell)

Written on March 8th, 2011 at 17:29 pm by shredder12

We all use ssh to access machines remotely, but not many know that instead of using a shell we can use ssh to simply run a command on the remote system. Just add the command, you want to be executed, after the user@host part and instead of throwing an interactive shell, ssh will run the command on the remote machine and show you the output(if any).

Here is a simple illustration:

Live Bandwidth monitoring became easy with Netmonitor screenlet

Written on August 14th, 2010 at 15:56 pm by shredder12

So, I think my search for a live network bandwidth monitor finally ended with this screenlet, netmonitor. Bmon and vnstat were working fine, but I was looking for something that can be present all the time on the screen without hindering other apps. A Screenlet was indeed the best option to go for.

Monitor your Internet Traffic Stats using Vnstat

Written on December 18th, 2009 at 21:00 pm by shredder12

A few days ago, I got the last month's Internet Bill. And due to overusage I had to pay 4 times the usual. That's when I realized that I definitely need to keep a check on my Internet usage. Vnstat is a simple console based tool built for such purposes. It keeps a log of the network traffic for the selected interface(s). It can show the usage stats in various formats (daily, monthly even live mode is available). It has proved to be a real life(actually money  ) saver for me.

SSH login without Password

Written on November 14th, 2009 at 00:44 am by chia

Alright! So this one day, I'm talking to a friend. She's telling me about this real cool movie she heard about...2012 or something (which btw... WATCH! ). Now I'm also typing my password on an ssh server, and I happen to mistype. Now I have a feeling I've done so, so I press Backspace till I think nothing could ever have lasted here and type again. My lucky day it was, for I happen to mistype again. That was when it hit me! There's gotta be a way around this password thingy. This is why I love being a Linuxer. There's always a way out of everything!!!

How to: Mount Remote Directories using sshfs

Written on September 12th, 2010 at 04:03 am by shredder12

So, we had this lab last week, doing some hands on work on Xen. While performing a task, one of the requirements was to make the directory structure look exactly the same as the one on the remote machine. One way, was to manually change the directory contents - filenames etc. and make it look similar to that on the remote system(pathetic way ), the other was to mount it remotely(better way). Thats when I came to know about this really quick and secure way of mounting remote locations using sshfs.

How to enable file sharing and receiving over Bluetooth

Written on November 25th, 2009 at 03:54 am by shredder12

We can easily send files and browse other bluetooth enabled machines using gnome bluetooth, the default bluetooth application of Gnome. I was pretty happy with this utility until one day I found out that I didn't know how to receive any file over bluetooth :o . I couldn't find any receiving option in the bluetooth applet. This was when I came to know about "gnome-user-share"(a great app) using which you can not only receive but even share files over bluetooth.
