Anyone know how to change user on Raspberry Pi GUI login?
by Chris Green 06 Sep '15

06 Sep '15

As per the subject. I have a Raspberry Pi with the latest raspbian installed. I've told it to run the GUI at boot. I want to change the user that it boots into, i.e. I don't want it to boot into the default user 'pi'. How does one do this? Google searching brought up all sorts of things about changing the pi login but not what I wanted to do. -- Chris Green

hosts.deny

Hi y’all! Could someone enlighten me about hosts.allow & hosts.deny please? I was reading up on linux networking, and it said I should consider the contents of these files. So networking aside, I've read up a bit and am a lot confused. As far as I can find, 1) if there's an match in hosts.allow an address is allowed to contact the machine. 2) if no match in 1), then if there's a match in hosts.deny, then the address is not allowed to contact the machine 3) if no match in 1 or 2, then the address is allowed to contact the machine. Is this right so far? If so, what's typically in hosts.deny? I ask because I've obviously edited this in the past - I have a vague recollection of doing it because I couldn't get anything working and I just stripped it all out - I know - a very very bad idea. All I've got in there is: ALL: ALL: ::1 As far as I can figure out, the first line, ALL: would do nothing. ALL: ::1 I think would block all IPV6 addresses from contacting. Is my interpretation of the above right? What's typically in the hosts.deny for a server? If it's set up to block by default, then what should I enable? Is it sufficient to use netstat to work out what's listening for a conversation and just allow these things if I think they should be allowed. If so what's the correct use of netstat to find out? If I have things running as cron jobs rather than as a daemon to check things, do I have to specifically allow these to contact the outside world, or is hosts.allow/deny just for daemons? Lastly, does this work like a firewall? As I have firewall already set up, is it a good idea to spend time on hosts.allow/deny as well? Any advice appreciated muchly! Steve

Linux laptops

So my main HP Pavilion laptop recently died ... it looks pretty permanent. It had a fairly good run, so I'm going to have to start looking for a replacement. Just wondered if anyone had any interesting thoughts or suggestions. I'm looking for a main PC. Sort of interested in shared tablet things like the Lenovo Yoga 3, though I'm not sure if it's a mite small. I see there has been some success getting Debian running on it.

Cambridge Beer?
by Brett Parker 03 Sep '15

This probably more belongs on alug-social, but as we've not had a post on there in, like, totally forever... Anyone around the Cambridge area fancy a beer or 3 tomorrow? I recommend the Haymakers, but am happy to be convinced of the merits of other pubs... Cheers! -- Brett Parker

Disc Errors
by Chris Walker 02 Sep '15

02 Sep '15

Hello, I have 3 SATA discs on my machine. One has Windows on it, another has Mageia 5 and the third is designated as Disc_Swap_Space to allow me to swap files between Windows and Mageia. It's formatted to NTFS. I prefer that to allowing Windows to write to any linux drives. But even though the swap drive functions perfectly under Windows, Mageia won't mount it. It complains 'non-zero exit status 14' and say that the file system is unclean. But I've run all the checks under Windows and that thinks it is clean. So how can I persuade Mageia to use it again? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|
