Hi,

That's almost certainly not correct, no. Your Internet provider is extremely unlikely to have the whole of 46./8 allocated to them. That'd be over sixteen million usable IPs, and a fairly...

Hi,

To put it as simply as possible, in any given network range the very first address and the very last address are not usable for hosts. The first address is the network address, and the last...

Hi,

Firstly, from just looking at a single IP, you can't tell how large the network it's a part of is. You need to know the netmask. So for example, if I had an IP of 192.168.1.10, that doesn't...

By changing the CIDR suffix to 25 , you create...

Hi,

I'm not quite sure what your question is, so I explain a bit more.

SSH: Local Port forwarding

Local Port forwarding in SSH means that a listening Port on the local side is opened and...

Hi,

The percent sign (%) at the start of the line signifies that this is a UNIX group name, and not a username. So it will affect all members of the group called unixforum, and not simply one...

Hi,

You do it exactly the same way. The ssh command itself doesn't care what or where a host is, it will just try to connect to it. So long as the hostname you use can be resolved, or you're...

Hi,

Interesting. I hadn't heard of this before, but from some quick Googlings it seems that this is the default behaviour of sudo on openSUSE. If you edit the sudoers file you'll probably find a...
