Re: Tutorial 5 - Question 10

The things sort sorts on generates an order, based on what is around it. If you filter out those things first the order could be slightly different, especially where the order is undefined (such as ordering by size and all are the same size). Ultimately both methods form the right answer, it is simp...

Re: Network Error: Software cause connection abort

Nothing has changed at my end.
If restarting putty doesn't help then there is not much which can be done.
I guess the timeout is at your end... Maybe a bad network, bad ISPs, or a nat cache in your router which is too small...
Sorry

Re: Longer time?

You get at least the time shown, and if resource is plentiful you get a hold 5 mins to go.
Free users compete for resources, so at busy times you might be kicked to let another free user on.
It is free after all...

Re: Fedora 15 not available

Just use Centos7, which is a clone of Redhat 7.
This is the basis for Fedora 19 or so.
They are all very similar.

Re: Tutorial 1: Question 5: file size

Yeah files in blue (and lines in ls -l which start with a d) are directories not files. If the question asks about files then in ls -l the line behind with a hyphen.

Re: The root topic

Usually you need a password or a special permission to become root.
However many of those systems in linuxzoo have weak security in this regard just to make learning easier...
So in short Linux is generally very secure.

Re: Connection Issue: "Closed by foreign host"

Your VM does not last forever, and when you get a new one then all previous changes are lost. It doesnt happen very often, but for instance this week I was doing some reimaging of servers to fedora 22. When this happens you need to revisit one of the tutorials which has a create demo account at the ...

Re: Connection Issue: "Closed by foreign host"

The machine only stays running while you have at least 1 browser window on the linuxzoo.net site.
If you navigate away for some reason, the machine shuts down a few minutes later.
Could that be the issue?

Re: Linux Networking

Not sure. It depends on the bit you are stuck on. To be fair the site is really designed for my own students who are following a taught module, and the slides they use may not be the ones you have access to. However I dont do anything crazy, so it should all be regular things which can be found in m...

Re: Internet Connection ...

Almost no connection at all.
I used to have a more generous policy, but then people launched attached against websites from their virtual machines.
I cannot have that, and there is only me running the service, so far easier to remove the access.
Sorry

Deleted users

Sorry, I was deleting a set of phpbb users who was spamming me, and I accidentally deleted a lot more users than I meant to... Unfortunately there is no easy way back.

Re: Questions about your videos

umask only effects permissions of files and directories after the command is executed and only for the duration of that login session.

You get a different output as the umask is set when you login to 022 in one of the login scripts.

Re: Tutorial 5 Question 13 keeps failing me

Do you have files in home demo, and is one of them s1? Are you CDed to /home/demo?

Code: Select all

find /home/demo -newer s1 | tee /var/tmp/t1
That seems find to me, but this is simpler...

Code: Select all

find /home/demo -newer s1 >/var/tmp/t1
