Oh, if you open several sessions to a single host, the ControlMaster options are awesomely kickass:

1
2
3

Host *
ControlMaster auto
ControlPath ~/.ssh/control-%r-%h-%p

The first session to a host will create a socket of the form

1	~/.ssh/control-username-hostname-22

. Any subsequent connections to that host will use the socket giving you a blindingly fast login

My ssh config has started looking like this:

1
2
3
4

Host nerp
Hostname nerp.evil.ie
Port 22
User niall

I also have a single host in front of all my home machines that I use as a bastion, so for those hosts I have something like:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

Host home
Hostname my.ext.hostname
LocalForward 2222 toast.int:22
LocalForward 2223 scolex.int:22
User niall

Host toast
Hostname localhost
Port 2222
HostKeyAlias toast.int
User niall

Host scolex
Hostname localhost
Port 2223
HostKeyAlias scolex.int
User niall

So to access any of my internal machines I just need to

1	ssh -N -f home

and I can then access any of my LAN machines using

ssh toast

What finally made me use Linux full time and ditch Windows completely years ago was this most wonderful tool that I could not live without…

Yep it’s OpenSSH.

The most utterly fantastic software tool ever. Thanks for your tips, some gems in there I wasn’t aware of…ah so much to OpenSSH, no doubts I’ll discover a few more gems in the years to come!

Cheers
