Quick Connect through Jump host via proxy

When we have hosts shared with ssh-keys, from home network to office network via proxy, then jump host.

This simple ssh/config saves lots of manual work

Host jumphost
        HostName jumphost.my.home.net
        HostKeyAlgorithms ssh-dss
        ForwardAgent yes
        LocalForward 3128 proxyhost.my.home.net:3128
        User sanjeev
        StrictHostKeyChecking no
        ConnectTimeout 30
        KeepAlive no

Host *.my.office.net
        HostName %h
        User sanjeev
        ForwardAgent yes
        ProxyCommand ssh jumphost nc -w 120 %h %p
        StrictHostKeyChecking no
        ConnectTimeout 30
        KeepAlive no

Now from your laptop you can do seamless connection, for any ssh activities


 ssh host1.my.office.net "cat watch.status"

This goes through  proxyhost to connect to office network, login to jumphost and connect to office network host, cat the file watch.status from host1, in office network :)
