The task: generate random mac when an interfaces comes up.
#this does work to generate a random mac
echo '00 60 2f'$(od -An -N3 -t xC /dev/urandom) | sed -e 's/ /:/g'
the inside of /etc/network/interfaces:
auto eth0
iface eth0 inet dhcp
#This works:
hw-mac-address aa:bb:cc:dd:ee:ff
#while this does not when I ifup eth0:
hw-mac-address $(echo '00 60 2f'$(od -An -N3 -t xC /dev/urandom) | sed -e 's/ /:/g')
Any thoughts or suggestions?
I am trying to use the default network manager for ubuntu 13.10 to connect to networks. Despite any config changes for example, enabling UFW, does not allow for the changing of this profile scheme. It is remains always faded as shown in the picture.
In my experience with Fedora, this similar network management style works right out of the box. Is this firewall zone config meant for a different firewall and if so, which? I've tried googling for 'ubuntu networkmanager firewall zone' but haven't gotten any relevant results.
Please advise, thanks.
What (if any) are the significant differences between netcat-traditional and netcat-openbsd?
I'm having trouble finding any relative information. Anybody familiar that can offer some insight?
I installed likewise and joined my an active directory domain.
I'm finding it's a bit unclear on how the default authentication works.
Do I have to do any extra configuration to enable kerberos?
If I do, then what authentication method is default?
I was experimenting with an idea and /boot was put on the first 256MB of a 1GB flash drive.
Windows destroyed the whole scheme when trying to add an NTFS partition after it in the unallocated space.
Can I make a new /boot without having to reinstall? The rest of the partitions are untouched and in perfect working order.
Please note that it's not the Master Boot Record that was destroyed, but the entire /boot partition. So this problem cannot be solved just by reinstalling the GRUB2 boot loader.
