[QUOTE=lavacano;48482958]I think in the US channel 14 is use primarily by government and/or medical equipment.

I could be full of shit though, I never actually bothered to look it up.[/QUOTE]

Being reserved for use doesn't mean it's actually in use, so there's that.

[QUOTE=DrTaxi;48484948]Being reserved for use doesn't mean it's actually in use, so there's that.[/QUOTE]

Nothing comes up on my phone when I use wi-fi analyzer, but since my phone is a consumer device sold in the US it's possible that channel 14 is completely disabled on it.

We may never know.

So I updated grub and now I no longer have wifi or sound on my laptop running Fedora 21. Also now for some reason I have the Fedora 17 hotdog boot screen. Anyone have any clue what the fuck is up an how I can fix it?

[SuperPlamz]

I've been having the strangest issue with my Linux partition lately.

I'm running the latest version of Linux Mint with KDE on a computer I can't readily access, and whenever I insert a certain USB, it lags for a few seconds and then the entire system straight up freezes.

Any ideas as to what it could be?

Can you guys recommend a good, tiny notebook to put Lubuntu (or any other really light distro) on for university?

I'm thinking of getting an HP Stream 11 and putting Linux on it for notetaking and general use, while bringing my main desktop with me for my dorm and all the more involved stuff. Thoughts?

Something cheap like that should do well, just avoid anything with a touch screen. Not very great in any distro yet. As for what to put on it, for just notetaking and browsing I'd recommend throwing on a window manager only distro. Super lightweight and snappy, I use one for a system at work and I idle at under 200mb of RAM used.

regarding distro, if you want to go as light as possible I'd definitely start with whatever the barebones Debian distro is called, Arch, or whatever else that's as barebones as possible. of course it'll require some knowledge, but it'll get you a very light system if you know what you're doing

[lavacano]

If the CPU doesn't blow chunks and/or you feel like playing with distcc Gentoo would also be a good option

Debian with no "extra software" from the installer

I'd recommend Debian over Arch since it's less likely to break

I recently moved (and thus switched ISPs) and now I can't access my server over the internet anymore. Every request to my public IP from outside my network fails, even pings. Inside the network it works fine, but I suspect that's because it can tell that the origin and destination IP are the same and is taking a shortcut.

Could this be due to misconfiguration on my end? Or is this my ISP's doing?

Have you checked that the appropriate ports are actually open? Some ISP's block server oriented ports.

[larikang]

I think that might be it. I can SSH from a remote server on a non-standard port, but HTTP and ping don't work. That is some bullshit.

[mastersrp]

[QUOTE=Larikang;48505725]I think that might be it. I can SSH from a remote server on a non-standard port, but HTTP and ping don't work. That is some bullshit.[/QUOTE]

If it's behind a NAT firewall / router, then you won't be able to ping it, as ping isn't a port-based system.

[larikang]

I can ping the router using its internal IP, so unless my ISP is blocking pings I would expect to be able to ping it on its public IP.

I just set up my router to forward 8080 to 80 and now I can serve HTTP traffic over 8080, so it definitely looks like my ISP is blocking at least ports 80 and 22.

Call your ISP and tell them to stop sucking dicks.
Although using SSH on port 22 is ill-advised, since there's many bots sweeping IP adresses and checking common ports.
Using non-standard SSH port is no excuse for not using other security practices for SSH though.

I use 8080 and 22 is a honeypot. 8080 is great because pretty much every network allows that port.

[lavacano]

I use 40022 because nobody ever uses the 40000s for anything

I use a port generated securely(tm) by bash' $RANDOM btw

[Ananace]

I use fail2ban.

[QUOTE=Van-man;48509467]Call your ISP and tell them to stop sucking dicks.[/QUOTE]
I called them and apparently I need to upgrade to their "commercial" internet service in order to stop them from blocking ports. Their commercial service costs over twice as much for a slower connection and it requires a three year contract.

Port 8080 it is, then.

Any suggestions on how to improve my knowledge with Linux? I was working with my boss today on a few Linux boxes running a mail server, RADIUS, and mysql and I just got so lost. He's so damn fast.

I've been using it as a desktop OS for years, and my only home OS for the last few weeks. Same with servers. I've been learning as I do for quite a while, but there seems to just be so much stuff I'm missing. Guess that's the case with everything computers though...

[editline]22nd August 2015[/editline]

I guess what I'm worried about is the fact that part of my job at work is actually a Linux admin. I mean I know more than all but 3 or 4 people at work, but compared to some of them it's woefully incompetent.

[QUOTE=ace13;48511739]I use fail2ban.[/QUOTE]

Fail2Ban is great, but it is no replacement for using a non-standard SSH port and avoiding getting DoS'd or DDoS'd.

Try new things out. Setup virtual environments and do really stupid shit. Figure out why it was stupid. Just try shit, and keep testing new things out, and continually figure out why things break.

instead of using online services by companies, try setting up your own replacement services with a Linux server and available software.

For example:
Gmail? Dovecot.
Dropbox? Owncloud or Syncthing.

And so on, but remember to read up about securing your server from both data loss and intrusion.

Use terminals as much as possible

[supervoltage]

Hey guys, it's been a while since I posted in this thread. Once again I come with a strange issue. I'm running Arch Linux x64.

I wanted to change the governor of my CPU to 'performance' with cpupower to test a thing, but I was greeted with this lovely error:

supervoltage@svlinpc ~> sudo cpupower frequency-set -g performance
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?

Of course, I'm stumped. I decided to check the frequency info from the same program:

supervoltage@svlinpc ~> sudo cpupower frequency-info
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  boost state support:
    Supported: no
    Active: no
    2400 MHz max turbo 2 active cores
    2400 MHz max turbo 1 active cores

I had an "A-ha!" moment upon seeing this, and decided to see if the proper cpufreq module is loaded:

supervoltage@svlinpc ~> lsmod | grep -i cpu
acpi_cpufreq           20480  0
processor              28672  1 acpi_cpufreq

.. and it seems to be loaded.

I decided to run i7z to see if it actually sees the CPU's stuff, and it does actually see it properly:

Cpu speed from cpuinfo 3383.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 3383 MHz
  CPU Multiplier 24x || Bus clock frequency (BCLK) 140.96 MHz

Socket [0] - [physical cores=2, logical cores=4, max online cores ever=2]
  TURBO DISABLED on 2 Cores, Hyper Threading ON
  Max Frequency without considering Turbo 3383.00 MHz (140.96 x [24])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  24x/24x/0x/0x
  Real Current Frequency 1844.03 MHz [140.96 x 13.08] (Max of below)
        Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %  Temp      VCore
        Core 1 [0]:       1844.03 (13.08x)      1.28    2.14     1.7    95.5    38      0.0000
        Core 2 [1]:       1475.13 (10.47x)      1.11    0.778      1    97.7    40      0.0000





C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver modes with cores idling)
C3 = Cores running with PLL turned off and core cache turned off
C6, C7 = Everything in C3 + core state saved to last level cache, C7 is deeper than C6

Does anyone know why my processor doesn't seem to have a scaling driver? I've looked all around the web with no working solutions found. Any help is greatly appreciated!

While not strictly a Linux issue, I have an issue with Steam, where it seems to detect my controller wrong. That is, it detects the correct controller, but the controls are wrong.

I've tried correcting them numerous times, but now it just says it detected the same controller 20 times.

Is there any way to remove the Steam controller settings?
