Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm not exactly a newbie to linux, but I'm no expert either. I've got user level experience on debian based distros but no more.
My problem is that I'm not able to ssh within my lan on fedora. I have two desktops and a laptop (all running mint debian till yesterday when I switched one desktop and the laptop to fedora) connected to a router (belkin router in which I've made no changes since previously). Desktop A runs fedora, while desktop B runs Mint xfce. I am able to ssh from desktop A to B without any trouble but when I try to connect to my laptop (running fedora and connects via wireless) I get the "no route to host" error. I have tried slotting in the ethernet cable and trying, but get the same error.
I've enabled the ssh checkbox on the firewall and started up openssh-server on both systems. I am able to ping from desktop A to the laptop and the other way round without any problems. I've tried hunting around on google, but all the explanations are a little above my head.
I would be very grateful for any help in getting this problem resolved.
If you can ping from A to laptop but not B to laptop then "netstat -nrv" probably differs between A and B.
Is DCHP being used or are they static IPs? Has the laptop been rebooted after being plugged in to the ethernet?
I ran the netstat -nrv command on both the laptop as well as the desktop and they both return the same results as below.
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 p33p1
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 p33p1
The only difference is that for the laptop the Iface says wlan0.
I have enabled DHCP on the router and am able to connect to the internet on both systems.
No I did not reboot the laptop after plugging in the ethernet cable, but it connected, an ip address was assigned and I was able to browse the net.
Edit - I know it's probably something very small because I'm able to ssh from my fedora desktop to the mint desktop. It's probably some setting on fedora that I've not done on the laptop. Don't know what.
I've fixed it now. I disabled the firewall in the laptop and connected via ssh. Once I had obtained the key I then enabled the firewall in the laptop and could connect easily after that. Don't know why I couldn't connect even with port 22 open in the firewall, but I'm ok with this feature (if it is indeed a feature) in fedora that requires that I manually disable the firewall before another system can get the ssh key.
I appreciate the help guys. Thanks
