Logging in

Set up the SSH access from Skynet, and mount its storage on skynet. (log into skynet and type:)

cd ~/shf3/mid/ssh
cp niif/budapest budapest
cd ~/shf3/key/ssh

Then place your private NIIF key here, and rename it as:

mv <YOUR_NIIF_KEY> budapest.sec

You might need to export the private key from putty in OPENSSH format, if you used puttygen to generate the keypair.

Precompiled Environment

From Skynet sync up the precompiled environment:

 cd /share/niif/budapest
 sshput -m budapest -s .

Log into budapest: You can do this with putty, etc if you don't like logging into budapest from Skynet.

 sshto -m budapest

Then add the following into your .profile:

 PATH=$PATH:$HOME/bin
