Change Mac OS hostname

The hostname command was still displaying 'pc14.home' although I did change it in the System Preferences | Sharing panel where it was name 'myimac.local'.

Using:

sudo hostname myimac
only changes it in the current shell

The solution I found to change it for good is to use

sudo scutil --set HostName "myimac"

Soving AccessDenied on Google Cloud Storage domain mapping

As I was facing this again trying to create amp pages for my main site www.tekartik.com , here is a concrete example for my changes Adding the proper DNS redirection in my domain provider (OVH in my case) www.tekartik.com. CNAME c.storage.googleapis.com. This was first giving the error: <Error>   <Code>AccessDenied</Code>   <Message>Access denied.</Message>   <Details>Anonymous callers do not have storage.objects.list access to bucket www.tekartik.com.</Details> </Error> the solution was to configure my bucket as a website configuration : gsutil web set -m index.html -e 404.html gs://www.tekartik.com And to make all files I add public by default and not worry about ACL anymore, I can use gsutil defacl ch -u AllUsers:R gs://www.tekartik.com To make previous imported files public, I can use gsutil -m acl -r set public-read gs://www.tekartik.com

Simple Samba setup on Lubuntu

I have a simple lubuntu server where I setup a ssh server. While it is sufficient to access a driver/folder from another linux machine using sftp, it is a pain from Windows & Mac, so unfortunately, samba is still needed here. For simplicity I needed only one samba user that I could map to a single user on my lubuntu machine Following the various tutorial I ended up doing this with simple commands Install samba $ sudo apt-get install samba Add myuser to the samba $ sudo smbpasswd -a myuser Export the drive I needed (no guest user) $ sudo vi /etc/samba/smb.conf to add the following export (no real option needed here) [files] path = /media/music/files writeable = yes save and Restart samba $ sudo service smbd restart
