It may be related to an obscure old networkmanager bug, whereby it changes the |
| 20 |
hostname in /etc/hosts. I don't use networkmanager and I don't use xfce to |
| 21 |
comment on particulars, but here's some generic things to check: |
| 22 |
|
| 23 |
1. Have a look at the 'Host and domain information' section and at the 'The |
| 24 |
hosts file' section in the handbook and configure them accordingly: |

| 27 |
|
| 28 |
2. Does 'echo $HOSTNAME' show what you have configured in your system, after |
| 29 |
you restart networkmanager, or reboot? |
| 30 |
|
| 31 |
3. Have you added /etc/init.d/hostname to your boot runlevel? |
