ssh_config file equivalents of command line options - how to find?
by Chris Green 30 Nov '17

30 Nov '17

I had a hard time recently working out what the ssh_config file equivalent of the -L command line option in ssh was. The man page happily tells you that "Port forwardings can also be specified in the configuration file." buut doesn't tell you *what* the configuration file equivalent is. (It's actually a bit obvious - LocalForward). Is there any documented way of finding the mapping? I'm now after the config file equivalents for -f and -N if there are any. -- Chris Green

How to *start* a desktop remotely? (for VNC)
by Chris Green 23 Nov '17

23 Nov '17

How can one *start* a desktop (in my case XFCE on xubuntu) remotely? I have set up VNC to acces my home machine desktop but since it's not actually running a desktop as it's been rebooted the VNC client shows me nothing. Help!? I have ssh access to my home machine. -- Chris Green

4G data
by Phil Thane 19 Nov '17

19 Nov '17

Hi, Not really a Linux question, except that it'll be mostly Linux devices that use it... A few years ago when 4G was being tested in pilot areas, but not on the Llangollen canal, I wrote a piece for a canal/river boat magazine about using the internet afloat. At the time I borrowed some demo kit from suppliers and a boat from the Llangollen Wharf for testing and for photos. One option was a 3G USB dongle for a laptop, another was a 3G modem/router to create a WiFi hotspot. Or just use my old 3G smartphone and either a USB or WiFi 'tether'. Now down south I've got my own (very old and very cheap) boat and 4G is widely available. So should be great eh? Well not so much. As far as I can find out it is impossible to buy data only SIM cards with data contracts that last until the data is used. You have to buy 'bundles' of data/phonecalls/text and they expire after 7, 14 or 28 days. When I'm not on the boat I don't use 4G at all. When I am going away on it I have to guess how much data I might need and load up the SIM. Last time I did that the boat broke down, we came home early and £20 worth of data just expired at the end of the 28 days. With my old 3G phone (on PAYG) it simply used the same account for texts, calls or data - and I only enabled 3G when I really needed it. But it seems none of the phone providers will offer 4G that way. I can't see there's any technical reason, it's just that phone providers are conniving bastards. Does anyone know of one that has broken ranks with the cartel and will offer me what I want? -- Phil Thane www.pthane.co.uk phil(a)pthane.co.uk 01767 449759 07582 750607 Twitter @pthane

Python GUIs
by Mark Rogers 10 Nov '17

10 Nov '17

I've only just really started to use Python, so this is very much a novice question. I'd like to create a simple Python GUI to manage a configuration file. I'll be developing it on Ubuntu but it'll need to run cross-platform, which is one reason I picked Python. Anyone here have any recommendations as to the best way to do this? Google gives me hundreds of options which is great but I'm after anecdotes from people I (feel I) know. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Are there any Regular Expression gurus here?
by Chris Green 30 Oct '17

30 Oct '17

I'm fairly happy most of the time using REs and can come up with some hairy looking stuff occasionally but I can't, at the moment, see a way to do this:- I want to match two lines like the following using a Regular Expression:- abcmnoxyz ========= The first line is essentially random, the second line will be all the same character of a limited number of possibles (=, - and maybe a couple more). The lines can probably be required to be the same length but it would be nice if they didn't have to be. It would be OK to have multiple REs, one for each possible 'underline' character. It's not a fixed length by the way, the minimum length will probably be 4 characters or so. Can anyone come up with a way to do this? -- Chris Green

Huge increase in spam
by Laurie Brown 26 Oct '17

26 Oct '17

Hi all, Well, after many years of my Linux mail filters working very well, I've noticed a significant increase in spam over the last week, and last night I got 33 alone, an unheard of number. Has anyone else noticed this? I use postfix, blacklists, postgrey, spamassassin (and a Bayesian DB), with all the usual postfix settings to discourage spammers. I also use a honeytrap third party MX server which traps and records some spam. Normally, once in a while I'll see a small increase in soam, and then the RBLs kick in and it stops after a few hours. However, I can't even find much of a pattern in the emails; there are a couple of regular IPs - now firewalled out - but in the main they are random. There must be a massive Windows-based botnet out there with some new spamming software on it. It's certainly dealing with grey-listing now. Ideas anyone? Cheers, Laurie. -- --------------------------------------------------------------------- Laurie Brown laurie(a)brownowl.com ---------------------------------------------------------------------

wake up GUI
by Phil Thane 13 Oct '17

13 Oct '17

OK, I'm inviting trouble here but bear with me. I run an old desktop PC, headless as a file/webserver. My wife's PC backs up to it and I mirror most of my desktop on it using Nextcloud. My only previous experience with web servers has been running Wordpress etc on hosted platforms whee all the setup stuff is done via Cpanel. No Cpanel on my DIY server though so to make life easier it runs a desktop distro (currently Lubuntu) and VNC. I can do any admin via KRDC from my desktop. During set up all this works OK, but the Lubuntu desktop goes blank after a few minutes inactivity, KRDC connects fine but all I see is black screen. The only way I can find to get back in is to reboot (using SSH), restart VNC then re-connect KRDC before the blackout kicks in. A while ago I did this and tried to find a setting to keep the screen alive for ever, as there's no actual screen attached it would make little difference to power consumption. I thought I'd found it, but obviously not as it still blanks. Anyone got any idea? I'm not totally averse to CLI work, providing it's a simple command to solve a specific issue like this, but I really don't want to learn how to do everything I need to do on the server that way! -- Phil Thane www.pthane.co.uk phil(a)pthane.co.uk 01767 449759 07582 750607 Twitter @pthane
