General Discussion / Re: Secure build for a newbie
« on: January 05, 2021, 09:53:31 am »
Thanks very much for the warm welcome and so much info!

@Keith:

The UX32 is relatively modern but my one needs a lot of tlc (mobo battery is dead and I'd want to upgrade RAM and put in a clean ssd) and was temperamental enough with windows (driver issues mostly), let alone Linux. My main concern would be the laptop specific stuff like trackpads etc.

I'd be happy to take on the refurbishment project after getting some experience on a "clean" build on a virgin machine (possibly being too optimistic there?).

As far as security goes I'd already been looking at protonmail & thunderbird, so thanks for the recommendation.

I normally use Nordvpn for Windows and Android devices.

 There are a few low spec nucs that can be had for under 200 quid and I'm currently leaning towards a self build (in spite of the "not recommended" from simplynuc....) or finding a supplier who can set up libreboot or similar on a refurb Lenovo.

@David:

Unfortunately I've been pwn'd twice in the last 15 years and both were data breaches at companies I'd entrusted with my data....

As far as the build goes, I have dealt with CCL in the past and they were very good so that might be an option.

Cheers

Take a look here too - https://www.scan.co.uk/

I bought from these recently to do my first ever desktop build.  Good prices and service and advice if you need it.  (I have no connection to Scan other than as a satisfied customer)

General Help & Advice / Re: Linux Lite v1
« on: January 02, 2021, 09:36:59 am »
I've being playing with Linux Lite v1 on VB.  Realistically, what security and application problems might I encounter if I were to use this as a main OS on a proper machine?  The main use would be accessing the internet for business downloads, and spreadsheet display.

Hi Matt - Linux Lite is now up to v5.2 so you might consider getting that if you want the latest software etc?  You'll need to know what your system specs are on whatever machine you're thinking of using to determine if it will run 32-bit or 64-bit.  Many latest distros are now 64-bit only as the 32-bit technology is considered 'old-hat' but that's not to say that they are not available, just that the support for them is reducing and will disappear over time.

As for Lite as an OS - I have 2 old 32-bit laptops that I run Lite on, mainly as back ups if my main desktop rig plays up. Lite is still a proper OS, built with the same security standards as the full versions, it just has fewer software options available.  This doesn't mean you can't add stuff if you wish - you can - it just is 'small' to keep the ISO small.  For more information, look here  -

Hope this helps,

General Discussion / Re: How to tune reverse proxy
« on: December 22, 2020, 04:41:54 pm »
Hi, I want to configure firewalld (sorry no need additional proxy as apache, nginx or squid, I need configure redirect by firewalld or my existing reversy proxy). I have running reverse proxy polarproxy in machine 192.168.0.106 (192.168.0.1/24).

I want to redirect all inbound request to domain xxxxxx.com from proxy-machine to machine 192.168.0.102 (where working local clone xxxxxx.com, this site use not only port 80). Any other request to other domain need to going free to gateway of this network 192.168.0.1 and to inet.

My common idea is debugging project worked with strong cryptography. I don't see what exactly request send my frontend to backend. TSL 1.2 is mandatory for this project (domain name and certificates processing manually in frontend and this is huge part of code and this code impossible to comment). Therefore I have selected polarproxy to decrypt request from fronend to backend. I have this backend locally and machine with polarproxy in the middle between backend and frontend. But I can not tune redirect all request from this domain to my local server.

What command I need? Or maybe polarpoxy config?


I have no knowledge of firewalld.  However, it is used by RedHat and CentOs, amongst other OS's.  Perhaps your query would be better answered elsewhere?

See here - https://firewalld.org/  here - https://access.redhat.com or here - www.centos.org

Hope this helps,

Printers and Scanners / Re: Scangearmp2
« on: December 18, 2020, 04:47:49 pm »
As has been previously stated - if all you want to do is scan then Simple Scan 'should' fulfil that without further ado - and it would not work 'with' Scangear anyway, they would just exist side-by-side on the computer.  As Keith says, uninstall all Scangear files and test Simple Scan again to se if it does what you require.  You can always reinstall Scangear afterwards if needs be.

To completely remove Scangear:  Open a Terminal (click on the icon or press "Ctrl + Alt + T") and copy/paste this command after the prompt - sudo apt-get --purge remove scangearmp2 and hit Enter.  Type in your password when prompted and hit Enter again.

You may have to confirm this when Terminal halts (press Y to accept, then Enter) and all traces of scangear will be gone.  This should stop the error messages appearing when updating  ;)

For my part - you're welcome!  Glad you got it sorted.

Can you mark this as Solved?  Go to your first post, open it, click on 'Modify' then add 'Solved' to the end of your title line.  This can be a big help to others who may have the same issue in the future.  ;)

Printers and Scanners / Re: Canon Pixma Tr8550 printer
« on: December 03, 2020, 09:11:18 am »
I am new to Linux Forum and using Linux Mint 19.3 Cinnamon and have just installed a Canon Pixma TR8550 printer. I have installed Scangearmp2 from Software Manager and launched it. However it doesn't appear in the Graphics list. I find I have to launch it by opening Software Manager then Graphics and type in scangearmp2 in the question block. This opens the install block and from there I launch the scangearmp2 successfully see attachment. Is there any simpler way to do this?


Hi, and welcome to the forum.

I've not used Canon Printers so have no direct knowledge but printing /scanning issues in general can be problematic.  This is not a fault with Linux, more that the manufacturers do not always provide Linux compatible drivers for all of their products.  That said, look here -

http://ubuntuhandbook.org/index.php/2020/05/canon-printer-scangear-mp-ubuntu-20-04/

to see if that helps?  Alternativey, if all you need to do is scan - in Mint, go to Menu/Graphics/Simple Scan and see if that works.  And make sure your printer is switched on when you open the app.  ;)

hi all, new to ubuntu ,just trying to listen to amazon music,wont play, tried updating firefox but still no joy,thanks for any help

Hi, and welcome to the forum. 

Which version of Ubuntu are you running and is this your first try-out with Linux? 

To find your version, enter this into Terminal - (Ctrl+Alt+T keyboard shortcut or by clicking on the terminal icon) -
Code: [Select]
hostnamectl
and post the output.

Hi Stephen and welcome to the Forum!

I've separated your post as it's better to start a new request afresh rather than tagging on to someone else's - you are likely to get more 'reads' that way  ;) 

I have no knowledge of OS's on smartphones though others on here may be able to help.  Have you looked at the Pine64 website?  https://www.pine64.org/

General Discussion / Re: Bluetooth for Slax Linux OS
« on: November 04, 2020, 08:48:14 am »
Did you look at the link I provided?  It seems that Slax uses bluez module, not blueman.  There is a download available from the link - if that doesn't work, you can contact the developer directly. 

I have no knowledge of Slax but it would appear to be very niche and it is uncertain as to how much support is available.  If you still have issues, perhaps a move to a more popular lightweight distro would be advisable?  ;)

General Help & Advice / Re: Advice needed on new PC
« on: November 01, 2020, 08:14:13 am »
Hello folks,

Here's a link to my Ebuyer wishlist of components for the new PC.

I'd really appreciate any thoughts on compatibility and whether it should support Linux. I assume it would, since it's the same chipset as the board Rich suggested (Ebuyer hasn't got that one).

Most of the components seem to be oriented towards gaming, which I don't do, but the extra grunt wouldn't go amiss, especially as the whole lot comes in at £284.59 - less than half what I was thinking!

I'll reuse my case and PSU...

Looks ok to me!   ;)

Hello All

I am Cyrix james here and i am very new to Linux. I was looking for  a lightweight Linux and came across Slax OS. its super fast and works smooth.i am trying to install bluetooth module to it .i install blueman it got installed but when iam trying to open it doesnt open.more over when i checked the bluetooth status its shows the follwing messages
Failed to obtain handles for "Service Changed" characteristic.
sap driver initialization failed.
Sap-server:Operation not permitted(1)
which Bluetooth module works with Slax Os.
Kindly guide me to install it and use it .

Hi Cyrix james - and welcome to the forum.

Which version of Slax are you running?  You might take a look here -

https://www.slax.org/modules.php?detail=bluez&category=network

It appears that it depends on which version of Slax you have as to how the module is installed.

General Help & Advice / Re: Advice needed on new PC
« on: October 27, 2020, 08:07:33 am »
Thanks folks. I'll look into your suggestions.

Rich, can you please tell me which motherboard and processor you bought?

If I understand correctly, that combination dictates whether Linux will run or not...

M

Mobo - Gigabyte H310M S2V 2.0
RAM  - 8GiB (2x4) DIMM DDR4 64bits (from memory I think Crucial)
CPU  -  Intel Core i3-8100 (Coffee Lake?)
SSD   - Crucial MX500
and I put in the DVD writer from my old rig - not really necessary these days but I'm old school.....!

Running Linux Mint 19.1 Mate OS which has more stuff built-in than I will ever use but is stable and very fast - boots to login in 22 seconds.

IIRC, Scan's website will only show compatible components once you make your selection of motherboard.

Not the most exciting set-up but more than adequate for my needs, which are pretty basic, everyday computing and a good balance re: costs.   

I believe that most Linux OS's will run on pretty much any combination these days but it's always worth a 'net search beforehand, just to be sure.  ;)

Hello Folks,

My ancient self-build is on it's last legs so I need a new computer. I'm thinking of a small form factor. I don't mind whether I put it together myself or just buy it.

Obviously it needs to run Linux (Xubuntu).

I'm not a gamer, and I'd like to keep it to a reasonable price (£500 - £600 if possible, although I'm a bit out of touch with hardware prices these days. I can go higher if necessary).

Any suggestions please?

Hi Mike - I did the same thing last year and got my stuff from here - https://www.scan.co.uk/

They've a good reputation and don't, in my experience, try to push you into buying stuff you don't need while still giving advice on compatibility etc.  After a bit of research into the merits of various kit, I put together a wish list on their website and got a build quote for around £650.  I decided to build myself and got all the bits for about £350, so a significant saving.  Scan also do a nifty insurance - from memory is was £10 for 1 month and covered everything against failure - including anything you break yourself!  Well worth having in my case as this was my first self-build!  My rig runs a 500GB SSD with 8GB RAM with Mint Mate 19.1 O/S and is blisteringly fast - only 22 seconds from switch-on to login screen so there would be no worries about running Linux!  Obviously, costs would depend on what kit you choose........

NB:  I have no connection to Scan whatsoever other than a satisfied customer.

Hope this helps,

Rich

General Discussion / Re: Linux Mint, stuck in a guest account???
« on: October 14, 2020, 08:47:49 am »
I've installed Linux Mint 18.2 on an old laptop.  It automatically logs me in as a guest.
This means that I have no authority to do anything at all.  I've tried installing another OS in order to re-install LM 18.2, but my guest status means I can't do any of that.  Is there a terminal command I could use to start again please?
Grateful for any help and advice you can offer.
????????
Thank!

Hi David and welcome to the forums!

You might try this first -

When Mint boots successfully, click on Menu/Logout/Switch User.  Does this offer you the option to log in with your details?

Rich

EDIT:  I just spotted Keith's post - if my suggestion does or doesn't work, please post back and we can discuss the options available.  Keith is correct - v18.2 reaches end-of-life in 2021 and later versions would be a better bet.  Which one depends on your system specs, but there will be a good option available.  ;)

General Discussion / Re: Advice in getting a Linux system.
« on: September 29, 2020, 03:00:33 pm »
Hi Tony and welcome!

The reason there are so few choices of machine with Linux pre-installed is that Linux is relatively straightforward to install yourself, even for a complete beginner, plus the fact that the OS is free so no financial gain for the seller other than the value of the machine. 

If your device runs W10 then it is perfectly capable of running any of the latest Linux distributions (distro's).  There are many!  Echoing Keith's advice, I would recommend going for something more 'mainstream' Ubuntu, Mint, Peppermint, et al as they, generally, are more polished, have more software included as standard and have a greater user base, therefore more support available, should you need it.

You can easily download a distro of your choice and make a bootable medium to try out.  Go for a 64-bit version as many of the older 32-bit ones are now being discontinued.  32-bit OS's are still excellent, it's just that more up-to-date machines are all 64-bit capable nowadays so support for 32-bit is on the wane.  You can run the distro straight from the medium without having to install it first (a great advantage) to see if it meets your requirements but remember, any software run from a DVD or USB will always run slower than if it were installed to a HDD.  This is just the nature of the hardware and not a fault of Linux!  In fact, you'll be amazed at how fast Linux runs in comparison with what you are used to!

Personally I'm a fan of Mint, currently running v19.1 64-bit on my desktop and Mint Xfce 32-bit on 2 very old laptops - used as test mules and emergency back-up machines should the desktop play up, happily very rarely and usually from my own incompetence!

Also, no Windows software will run natively on Linux.  Some will run through the Wine emulator but with varying success.  If there are some Windows programmes that you just can't do without, better to keep Windows for them and do all your other stuff in Linux, whether in a dual-boot format or a stand-alone.  You will find that for most common requirements there will be a perfectly good Linux alternative anyway. 

Have a read through the links that Keith has provided and come back when you are ready to give it a go.  ;)

Hope this helps,

Rich
