[distcc] ssh speedup

[Kashyap Ashwin]

Hello,

The FAQ has some outdated information about fsh/autossh et al. Please
update to include SSH 2 specific information:

 

Make sure you have recent SSH (only on client side)

 

ssh -V

OpenSSH_4.6p1 Debian-5ubuntu0.1, OpenSSL 0.9.8e 23 Feb 2007

 

Create ~/.ssh/config, add this:

 

Host *
ControlMaster auto
ControlPath ~/tmp/master-%r@%h:%p

 

Then create the master SSH connection:

ssh -fMN <hostname>

 

Subsequent connections to host will now fly!

 

I got close to 10x speedup (not for compilation) to run subsequent SSH
commands this way.
