Question: I have a VM running Fedora 17 on VMWare over windows 7. I want to SSH to my university server from fedora but when I try something like:

```
ssh myuser@server.com

```

I don't get request for my password. If I try to SSH using PuTTY in windows, everything is OK.

Then I pinged the server and got the following message:

```
From 192.168.0.106: icmp_seq=2 Redirect Network(New nexthop: 192.168.0.1)

```

It repeated over and over. Anyone knows how to solve this issue?

PS: I tried NAT and Bridged network connection on the VM, but I'm not sure what this means completely, so I may have messed up somewhere around here.

Answer: 
On Fedora Core 18 (Gnome)

Using the GUI tools:

```
Applications > System Tools > System Settings > Brightness & Lock

```

From the terminal (to set sleep timeout to 10 minutes / 600 seconds, then require login after 15 minutes / 900 seconds):

```
gsettings set org.gnome.settings-daemon.plugins.power sleep-display-ac 600
gsettings set org.gnome.settings-daemon.plugins.power sleep-display-battery 600
gsettings set org.gnome.desktop.session idle-delay 600
gsettings set org.gnome.desktop.screensaver idle-activation-enabled 'true'
gsettings set org.gnome.desktop.screensaver lock-enabled 'true'
gsettings set org.gnome.desktop.screensaver lock-delay 900

```
For Centos 7 running MATE GUI, it's in the menu under `System -> Preferences -> Look and Feel -> Screensaver`. You can turn it off from here, as well as locking the screen when computer is idle.
Also, there is `Power Management` button in the bottom toolbar of Screensaver preferences windows where you can change additional settings like dimming the screen, turning it off after certain time, etc.
