PulseEffects Audio
by Phil Thane 27 Jan '21

27 Jan '21

hi, Long ago on a previous distro I used to use PulseEffects to enhance the audio output on my desktop. Until recently I wasn't able to get it working on Mint (Cinnamon) but now with a new repository it does, sort of. The GUI opens OK and the various options seem to switch on/off OK (previously everything was greyed-out and not working at all) but if I switch off 'Global Bypass' I get horrible distortion unless all the settings are at default. With Global Bypass on of course everything is bypassed so fiddling with the sliders has no effect. All I want is a bit of bass boost. Any suggestions? -- Phil Thane www.pthane.co.uk Tweet @pthane 01767 449759 07582 750607

cat docx files?

For years I've used "catdoc" to cat old msword docs. Is there an equivalent command for docx? (I don't want to have to open libreoffice or whatever) -- Steve Mynott <steve.mynott(a)gmail.com> cv25519/ECF8B611205B447E091246AF959E3D6197190DD5

Repairing/Copying Windows disk using Linux Tools - A bit OT
by steve-ALUG＠hst.me.uk 17 Jan '21

Greetings clever cloggses! Sprog's Windows laptop is occasionally saying "I have to reboot - disk error" "Check Disk" isn't really finding anything wrong. I used to be up to date with windows tools for fixing things, but now I'm out of date with Windows tools, though I'm up-to-date with Linux stuff. I'm wondering if likely that booting from Ultimate Boot CD and/or System Rescue CD and running fsck and proprietary disk check utilities (e.g. seagate's disk utility if the disk turns out to be a seagate) is a good idea. Is it possible to use DD to clone a windows hard disk, assuming the destination disk is bigger than the source. Once cloned, would the clone work as a bootable disk so I could swap out the damaged one and swap in the new one? Any advice appreciated. Anyone know a reputable computer fixer in the city? Thanks in advance. Steve

Are VPNs really this complex to install and use?
by Chris Green 14 Jan '21

I'm looking at ways of connecting a small Linux system (a Beaglebone Black, but a Raspberry Pi is near enough) on my boat in France which is headless and behind a NAT WiFi (or 3G/4G) server to my home desktop or laptop so I can 'talk' to it. Currently I have ssh reverse tunnels set up by outward connections from the remote Linux system that allow me to ssh into the system. This works OK except that the marina WiFi it uses is a 'captive portal' system where you have to open a web browser and it pops up a login screen where you enter name and password before it connects you to the internet. The connection, once made, stays up for several weeks but when it disconnects for any reason there's no easy way to reconnect automatically, has to be a human being to do it. So, I'm considering getting a 3G/4G USB dongle to connect via the mobile network so I don't have to jump through the marina's WiFi hoops. I can continue to do my reverse ssh tunnel connection but everyone I talk to about this says a VPN is the answer. However I'm having a hard time seeing how to get this installed and working without a huge amount of effort. For example wireguard is supposed to be a simpler, easier alternative to OpenVPN but take a look at:- https://www.wireguard.com/quickstart/ It's horrible! It's do-able, I can understand all the stages but it's just not nice. Similarly VPN tutorials are full of misinformation, take a look at this one:- https://thishosting.rocks/how-to-set-up-openvpn-on-ubuntu/ It's rubbish! ... and all the others I've looked at are either similarly wrong or more complex than the wireguard one. Is VPN *really* this difficult? If so I'll stay with my ssh approach. -- Chris Green

Unattended remote access - what ways are there to provide it?
by Chris Green 02 Jan '21

I have a Beaglebone Black (SBC like a Pi) on my boat in France that I want to be able to connect to using ssh, how can/should I do it? I have a number of possible solutions in mind but I won't give them here as that might prevent open and lateral thinking being applied. Speed is not an issue, a 2400 baud dial up connection would be sufficient. Security is not a big issue, there is no sensitive data on the Beaglebone Black. I guess it needs to be reasonably secure against misuse but thats all. It's inside the boat in a fairly secure marina so the hardware is safe enough. Cost is important, this isn't something I want to spend lots of money on. A solution costing £7/month seemed a bit expensive to me, I'm aiming at significantly less, one or two pounds a month is fine. The boat is moored in an urban environment, power is (fairly) freely available. When I visit the boat I have lots of time to do fairly complicated set-up if needed but once I've left it's totally inaccessible, it has to work totally unattended, there's no one to phone up and ask to 'press the reset' or similar. So, let your imaginations run wild and come up with some ideas! :-) -- Chris Green
