To access the local administration console within Dcache

ssh -l admin localhost -p 22223 -c blowfish service 

The default password is

dickerelch

Next Change the password by this series of commands.

ssh -l admin -c blowfish -p 22223 localhost
(local) admin > cd acm
(acm) admin > create user admin
(acm) admin > set passwd ${newPasswd} ${newPasswd}
(acm) admin > ..
(local) admin > logoff

To login to the administration console using ssh keys without a password is also possible.

To generate a key pair.

[synge@dev01 synge]$ ssh-keygen -t rsa1 -b 1024

Passwords can be left blank if the key is for automated scripting against D-Cache

The public Key should then be edited to have the ${USER}@${HOST} changed to admin@${HOST}. The ${HOST} variable does not seem important.

[synge@dev01 synge]$ vi .ssh/identity.pub 
[synge@dev01 synge]$ cat .ssh/identity.pub

admin@dev01.gridpp.rl.ac.uk

Add the content of the public key to the D-cache ssh servers authorised keys list.

[synge@dev01 synge]$ cat .ssh/identity.pub >> /opt/d-cache/config/authorized_keys

The ssh clients configuration needs editing to include the following values.

[synge@dev01 synge]$ vi .ssh/config
[synge@dev01 synge]$ cat .ssh/config 
Host dev01.gridpp.rl.ac.uk
Port 22223
User admin
IdentityFile .ssh/identity
Protocol 1
Cipher blowfish

Now we should have password free login if ssh agents are used, if not you will be prompted for the ssh pass phrase, and if this is not correct the server will fall back to the admin password..

[synge@dev01 synge]$ ssh admin@dev01.gridpp.rl.ac.uk

This shows that we have 3 public keys that are accepted by D-Cache to bypass the servers own password.
