Bruce said:

To copy from the canopus:/thuban2-backups/ to someone’s home folder I did the following:

1) ssh into thuban2

2) Become root:

# sudo su –

3) cd to the target directory where you want to copy the files

# cd /var/share/home/jweisber

3) Issue this rsync command:

# rsync -av root@canopus:/thuban2-backups/home/swiggumj/B1913+16 .

The only way I know how to get into thuban2 is to be on canopus or mirzam, and from there,

ssh thuban2

To do important stuff, one needs to have root (aka superuser) privileges.

I tried sudo blah blah blah with limited results.

Bruce says I need instead to do

sudo su – (that’s a blank followed by a minus sign)
