PPC iMac Network Fault

A PPC iMac was brought in and it was found that dhcp was not working (it wasn't receiving an IP address from the server).

It did work if the IP address was set manually. On further investigation it was found from the system logs that all dhcp requests were being denied. So the firewall was modified to allow dhcp requests and this fixed the problem.

Using Rsync

Some quick rsync examples

rsync -av /memstick/ /mymaindisk/
This will rsync the memstick directory to mymaindisk directory preserving all aspects of the files with the archive switch and the verbose switch will show whats happening.

rsync -avz /memdisk/ me@myserver:/backupdir/
This will do rsync over ssh rather than scp, using -a archive switch -z switch this signifies use compression over the link.

Ubuntu Server Screen Blank

Problem when rebooting Ubuntu 11.04 Server X86 after fresh install.
It caused the screen to be blank and a monitor message of overrange settings. This was traced to the setting of gfxmode=auto in the /boot/grub/grub.cfg file.

Note: you have to boot Ubuntu into rescue mode using the media CD/DVD/Memory Stick you used to install the system with.
From the command prompt make the /boot/grub/grub.cfg writable using chmod +w /boot/grub/grub.cfg command.
Now edit the file using vim /boot/grub/grub.cfg command.

The settings that worked for me were as follows gfxmode=1024x768 and with an entry gfxplayload=keep added directly after the gfxmode line.
After editing hit esc key then type wq and then hit enter this will write the file and quit vim.

Now reboot your system and hope it works.

What a mucking around to fix this stupid fault.
