Linux Heads

[NilsFG]

hmm yeah I've heard that Ubuntu is newb friendly, but I think if I wanted to have something like windows, i'd use windows.. I like how different some linux distros are, will learn it proper some time.

Thing with Ubuntu is that many people use it, so many support is available. Although I personally use Xubuntu on my linux laptop/VMs. It's basicly the same, only less bloat, but that's just a personal opinion. Also command lines are a proper handy tool when you learn how to use them. Use mine all the time on my mac and not just for developping etc.

All my servers run Debian, except VM hosts which run CentOS.

I know this is a Linux thread, but I just installed Windows 10 Technical Preview as a virtual machine in VMware 10. It's not too bad so far. You can get it if you have a Microsoft account (hotmail, etc).

Check it out because its where Windows is going.

So at work, we are migrating our Linux servers from openSUSE to Oracle Linux 7 which is a Red Hat Enterprise Linux clone as is CentOS. I am glad to be back in the realm of yum. I was getting tired with yast. But there are many commands that are deprecated, so I'm having to learn new ways of working.

Ifconfig, the old standby does not work anymore. It has been replaced by the ip commands like ip addr and route is ip route. Service may or may not redirect to systemctl, but systemctl is the new standard. Chkconfig is gone, replaced by systemctl commands. Netstat is being deprecated, being replaced by ss, but you can install it using yum install net-tools.

When installing, I've been manually creating the partitions like /boot, swap, /var, /usr, /tmp, /home and / but I left the default settings of OEL7 to minimal installation, but I have been finding it to be a bit too minimal with the software installed. I've had to install netstat with net-tools, dig with bind-utils, xinetd and traceroute.

You geeks have to watch this, even if just for the old equipment. It's hilarious and a true story.

^ Yeah, I would have to run that as a VM with a snapshot taken.

I knew I was a linux noob but fucking hell I didn't think I was this bad - Installed CentOS VM, everything going fine until I try and start it up and get stumped by this thing, no gui or anything



Where's the desktop?

[Phigure]

# yum groupinstall "GNOME Desktop" "Graphical Administration Tools"

Looks like you did a minimal install. Might as well run yum update while you are there. You are probably missing a lot of software and services, which is good when you do a minimal install, so you only have applications that you really need running on your server. You will find them soon enough when you try to run a command and bash tells you command not found. Yum will be your friend.

who needs tech support with ninjas like these

I never told anyone but I received my RHCSA6 last December.

Finji, take a look at Michael Jang's books if you want to become more acquainted with Redhat based binaries. You have a bit of a road ahead of you but I believe anyone can handle linux if they take their time.

I'm just interested in linux in general, not any particular version. I managed to set up an Arch VM and customize it a little bit, pacman is so good.

I was wondering if you had done that. Congrats!

the Arch wiki is really good. I installed it on my old Mac Mini.

Thanks! I will eventually pursue the RHCE7 but I think I need to broaden my knowledge of networking and C first. That way I can harden systems with more understanding.

I couldn't help but gush over the honeywell hall-effect keyboards in that video. I need something to pair with my IBM Model M and my beastly CRT.

I'm currently working on the CCNA Security. I did Linux+ and Security+ last year and my CCNA Routing and Switching at the end of 2013. At work, I am now responsible for hardening all of the new systems I build. I've been building both Oracle Linux 7, which is a RHEL 7 clone and Windows Server 2012 systems. We just got this cool tool called CIS-CAT to run on our servers to tell us what is vulnerable. I haven't had a chance to try it yet, we just got it this week.

I ran CIS-CAT today on couple of recent Windows Server 2012 builds and it's a pretty cool tool. It requires Java Runtime Environment for the GUI, but it can be run from the command line as well. For Windows, it seems to be mostly Group Policy hardening in Active Directory. I wasn't sure how this was going to play out, whether it would be registry edits and whatnot, but hardening GPO's in Active Directory makes sense. I'm not sure how this is going to play out with Linux yet, plus we need to set this up on a server to scan on the network. I just ran it locally today.
