Sharing files between Mac OS and Linux systems
by Jason White 09 May '20

09 May '20

I'm interested in accessing files on a Mac OS machine over the network from a Linux host. They're both my laptops, and currently on the same network, but this is not always the case (i.e., doing this over the Internet may be desirable at some point). I read a while ago that Apple was moving to SMB for file system access. Is this what I should be looking at? Are secure authentication and encryption supported? Or should I be considering sshfs or NFSv4, or something else? There's no LDAP infrastructure in my home environment. With thanks and regards, Jason.

Problem with very old Dell XPS M1330
by stripes theotoky 26 Apr '20

26 Apr '20

Hello to all, Have a problem with a very old Dell XPS M1330. The box is 12 years old (2008) and runs Ubuntu 10.04 Lucid Lynx. It has only been used recently to play frozen bubble as it has a very good keyboard. The problem: It does not pick the wifi. The switch on the side of the box doesn't seem to be working. I have checked the BIOS and both wifi and blue tooth seem to be turned on there (ENABLED). I tried iwconfig which listed the following interfaces and that nothing was wifi capable lo eth1 vboxnet0 I tried sudo ifconfig vboxnet0 up and sudo ifconfig vboxnet0 down which show I can turn the vboxnet0 interface on and off. With it turned on I again tried iwconfig and still there are no wifi capable interfaces. This happens with the Ubuntu that is on this box and with Mint 17 booted from a USB key. Any ideas? Is the wifi internal card dead? old system? Thanks in advance, Take care and be safe J. -- Stripes Theotoky -37 .713869 145.050562

HP Server
by Russell Coker 22 Apr '20

22 Apr '20

I just got given a HP ML 350 G6 server that I had hoped to use for LUV training etc. It has 18G of RAM (9 DIMM slots used out of 18 total and the only DIMM I could read was 2G), 2CPUs that each probably are in the 3000-5000 speed range according to https://www.cpubenchmark.net/ and 6*146G 15000rpm SAS disks. It's a nice mid range server. The problem is that it appears to have a broken power supply backplane (the thing that connects to the hot-swap power supplies). Does anyone know where to get a backplane cheap? I'm not paying $80 given the possibility that whatever damaged the backplane damaged the rest of it in the process. Does anyone have a similar HP system they want to use for swapping parts or something? Also as an aside I've got a box of 3.5" SAS disks. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Weird meeting request in Thunderbird
by Andrew Greig 19 Apr '20

19 Apr '20

Hi All. I have used Meeting Requests in T-bird for some time but recently I have had trouble with the Invitees dialogue. It used to be wholly contained within around 50% of a screen width, but now it spreads across three screens which is an irritation as I use only one screen. The info I need to enter is on the very far left and the OK Button is on the far right. Here is the link to my screenshots: https://drive.google.com/drive/folders/1MzJN0cBMY8r2Tx-Xzf9cFY-FM-99m27s?us… I have written to Mozilla to get a solution, but have had no reply. Perhaps there is an easy solution to this. Any help would be appreciated. Many thanks Andrew Greig

While searching for pulsars is unlikely to have any health effects, we could suffer the same fate as the dinosaurs so research into asteroids is a really good thing. Folding at home is a worthy project, but they probably have plenty of people subscribing to it now. If you haven't setup Boinc before then Folding at home is a reasonable choice for a first project.

Advice on broadband options
by stripes theotoky 14 Apr '20

14 Apr '20

Hi to all, Now my university is closed for the duration of the health crisis, I have to give at least 16 hours of tutorials / lectures a week via zoom. The audience varies between 20 and 80 students. As my only internet connections are: 1. is a dongle (with Vodafone) that has 3GB , and 2. my mobile phone with 60GB (also with Vodafone) I am urgently in need of a much better connection. Any advice on what and with whom? I am in rented accommodation in Macleod, pretty much a mobile blackspot, and the landlord doesn't like the idea of cable being brought to the premises. Thanks Joanna -- Stripes Theotoky
