[Dorset] Two Raspberry Pi puzzles
1. Some time ago (Aug 13) I asked for advice on how to use ssh between the 3 computers attached to my router. The solution I adopted was the hostname.local notation, suggested by Andrew. That continued to work until I had to re-install Raspbian (a cut-down(?) Debian Wheezy). Now it doesn't. A web search found a reference to Avahi as the source of the .local convention. And indeed my RPi doesn't have avahi running whereas the 2 other computers do and .local works between them. Clearly, I need to install avahi. But - is that the full answer? 2. On my re-installed RPi I added a new user and su-ed to it. Later on this user tried to do a bit of adminstration using sudo. Not too surprisinfly, I received an error message saying that this user was not a sudoer and I would be reported to the Thought Police! I looked at /etc/sudoers and found that it contains the standard entry: %sudo ALL=(ALL:ALL) ALL and that the new user is in group sudo. So why couldn't the new user sudo?

At a guess, the new user isn't in the 'sudo' group. -- Andrew. -- Next meeting: Bournemouth, Tuesday, 2014-04-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
