I made a VM for school. What van I run on it to impress teachers

Fri, 2017-05-26 04:50

I made a Ubuntu server VM (16.04) as part of a senior year project in high school. I need to present it along side a website we had to make. What can I run on it that would look cool for teachers and parents to look at? Thanks!

Antivirus for Linux (Specifically RHEL-based systems)?

Fri, 2017-05-26 02:39

With the recent Wannacry stuff, I have been more concerned with security. Remembering Shellshock and the GRUB backspace bug (that was REALLY bad), I would like to at least have SOME defense from my own dumb decisions (accidentally running chrome as root, that kind of thing).

If you use an antivirus, which do you use? If you don't and want to say that Linux never gets viruses, refer to and look at the number one most vulnerable piece of software.

Dual GPU and Wayland: How do they work?

Fri, 2017-05-26 01:10

So I have been reading articles on how GNOME is about to add support for launching apps with your preferred GPU. How have they gone about implementing it?

Also, can't the graphics rendering be distributed automatically and "smartly" among the GPUs for the most optimal result?

Long shot, anyone know about OPUS audio?

Fri, 2017-05-26 00:59

I just discovered opus, and am trying to find a replaygain editor. I found this, But it seems like it does nothing, or i dont know how to use it. And it says that it is half done.. so.. Tried it on a raspberry.

Soo, how should i proceed, the neat thing about opus is that it supports multiple audio tracks seemingly without hassle. This is one of the reasons I would like to get this going.

Thanx in advance Cheers

Encrypt passwords in shell script

Thu, 2017-05-25 22:47

I got a RedHat 6.3 server that runs some scripts to copy files over sftp with an AIX server. But the credentials to log in the ftp server are stored in variables inside de script, in plain text. I need to "encrypt" these credentials to hide it from anyone who can access the script. I did some research and basically found about SHC and base64 encoding.... but I need to know if there is any other method that I can explore.

To connect today, I use the following command:

lftp -c " ; open -p 4098 sftp://$USER:$PASS@$HOST;

Intel Hyper-threading (SMT) and network performance

Thu, 2017-05-25 22:12

Cross-posted from /r/vyos

Does anyone have any solid information on whether or not hyperthreading should be enabled for the best network performance on Linux (especially in the context of routing performance)?

I've seen people claim it should be enabled: (in the context of a CDN however)

"I don't see any reason not to enable HT."

(This is in the context of web/database servers- though in the context of networking- and there are no numbers to back up their claims)

I've seen posts where the results are inconclusive:

And I've seen a number of posts saying HT is a bad idea (because, for example, it can increase interrupt handling latency):

(Many of these are older posts at this point)

Does anyone know what the right answer is? (Especially with respect to VyOS if you happen to know).

We're building a couple of VyOS routers (based on the Jetway 1U 8 port rackmount systems) for testing. The primary difference between the i5 and i7 is HT and from the reading it seems like HT would actually be a hindrance not a help. If that's the case- we're probably better off saving some money and going with the Core i5 instead of the i7 with HT disabled (even if the i7 is a tiny bit faster and has a bit more cache).

Does anyone have conclusive data one way or the other?
