Remote connect with SSH on Mac

for Kusum and other "admin" people

These instructions are for Mac users.
See also instructions for Windows users.

Once-only setup
Follow the setup instructions in SSH HowTo and also do as follows.

Install both macFUSE and SSHFS from osxfuse.github.io
allowing security settings for MacFUSE, then restart your laptop.

Set up a command to connect to some drives.
Note that bianco H and enna X home directories have been "merged",
now named M (because Windows MCS use H for something else).
NOTE: replace MATHSNAME by your Maths login name!

    U=MATHSNAME
    echo "# Script to mount some sshfs drives" > ~/bin/mdrives
    M="mkdir -p"; S="sshfs -o follow_symlinks -o uid=$(id -u) -o gid=$(id -g) -o volname"; V="-p 12022 $U@localhost"
    N=M-home;	  D=.;        echo "$M ~/$N; $S=$N $V:$D ~/$N" >> ~/bin/mdrives
    N=L-local;    D=/usr/sms; echo "$M ~/$N; $S=$N $V:$D ~/$N" >> ~/bin/mdrives
    N=N-nobackup; D=/nb/$U/;  echo "$M ~/$N; $S=$N $V:$D ~/$N" >> ~/bin/mdrives
    N=Y-shared;   D=/users/misc/shared;   echo "$M ~/$N; $S=$N $V:$D ~/$N" >> ~/bin/mdrives
    N=T-teaching; D=/users/misc/teaching; echo "$M ~/$N; $S=$N $V:$D ~/$N" >> ~/bin/mdrives

Set up another command to disconnect them all.

    echo 'for n in ~/[A-Z]-*; do umount $n 2>/dev/null; done' > ~/bin/udrives

Fix permissions of the command files we created
```
    chmod 700 ~/bin/mdrives ~/bin/udrives
```
Those enna "drives" M-home etc will be under your "home", not under
Documents (where they might be hard to find amongst the many objects).
To see them in Finder, you need to add your Mac "home" to your Favorites:
in Finder choose Preferences, then Sidebar, and place a tick next to the
"home" icon (that shows your username): see demo here.
For printing setup follow the instructions in SSH HowTo CUPS and
Visitors printing Mac so using http://localhost:12631/printers/eslw or similar.

How to use (daily)

In a terminal window, type command
```
    ssh MATHSNAME@enna
```
(with your Maths login name) to log in. In this enna window you can type commands
```
    mupdate
    rosters
    web-minutes
```
and similar; leave it running anyway.
In a new terminal window on your laptop (not the enna window),
type command mdrives to connect to your drives.
See all your files in the various folders, use them as "normal".
Print to any printers you had set up.

When done for the day, close everything in the "right" order:

In a terminal window on your laptop (not the enna window),
type command udrives to disconnect your drives.
Close all your mupdate, rosters etc windows
Type exit to close the enna window
