ProxyCommand error

This week's lesson in internet connectivity is a variation of the classic debugging best practice blame yourself first.

Attempting to ssh into server dev.example.org set up in .ssh/config as "example" with

ssh example</a> resulted in:

<output>
/usr/bin/netcat: No such file or directory
ssh_exchange_identification: Connection closed by remote host
</output>

This error was not caused by the far-off server i was trying to reach, but by our intermediary server being used to do the proxy.

There was indeed no /usr/bin/netcat directory.  whereis netcat came up with /bin/netcat
Using that instead worked.
