There are many alternatives to choose from when we are talking about *nix server monitoring. Just tested two, ntop and munin. Both comes with a nice browser user interface. Ntop is focused on network traffic monitoring. Munin draws nice graphs and it’s really easy to setup. I choosed munin for my file server because it gives a clear overview of used system resources.
Mounting a remote folder in local network with nfs is quite simple and the topic is covered in many sources before but this formula worked for me. This example is for Debian server and clients. All steps are done as root.
Setting up the server
1. Install packages for nfs server:
# apt-get install nfs-kernel-server nfs-common portmap
2. Edit exports file:
# nano /etc/exports
3. Add wanted clients:
/path/to/shared/folder client1-ip(rw,sync)
/path/to/shared/folder client2-ip(rw,sync)
Note. No space between client-ip and (permissions).
3. Load new settings and restart related services:
# exportfs -a
# /etc/init.d/portmap restart
# /etc/init.d/nfs-kernel-server restart
# /etc/init.d/nfs-common restart
Setting up a client
1. Install nfs support for a client:
# apt-get install nfs-common portmap
2. Test mounting with:
# mount server-ip:/path/to/shared/folder /path/to/local/folder
3. If that worked you can add it to fstab. Open fstab for editing:
# nano /etc/fstab
4. Add the nfs mount :
server-ip:/path/to/shader/folder /path/to/local/folder nfs rsize=8192 0 0
That’s it. Now the remote folder is automatically mounted every time the client is booted.
Found a nice source of fresh deb packages. Just download and install no compiling required.
In Ubuntu you cannot directly sudo cd folder. But in sudo bash you can.
So enter to bash mode:
$ sudo bash
Now you can sudo etc.
# cd
Leave sudo bash with exit-command:
# exit

IP and gateway info can be found with ifconfig:

From WiskiHow to use screen.
Debian: #apt-get install screen
After installation just launch the program by command screen. Next start some other program, like top or nano, inside the new session. Now you can safely detach from the screen session by pressing Ctrl + a and d. You are back in your original session. Logout and come back later. When you return just give screen -r command and you are back in your screen session.
