Accessing Carbon
To use Carbon you need an active user proposal and your Argonne domain username and password. You must renew your password about every 6 months.
From an Argonne-operated workstation
Connect with a Secure Shell client program to clogin.cnm.anl.gov.
From any other computer
Employ one of the following mechanisms:
- SSH gateway (available for all users – see below),
- Argonne VPN (available for Argonne employees only).
Using the SSH gateway
The CNM ssh gateway is mega.cnm.anl.gov.
- To access the gateway you must be a user on a CNM proposal that is active or has expired within the last 6 weeks.
- You must use a password to connect to the gateway. For subsequent (forwarded) connections you may use ssh public keys.
- The gateway is only used for port forwarding. You do not need to run any commands or store any files on it once your ssh program is properly configured.

SSH GUI Applications

- Virtual Desktop (VNC)
Note for CNM workstations on the APS network
For users with workstations that are still on the APS networks, there is a conflict of kerberos tickets. Prior to accessing the cluster, the APS ticket must be destroyed, so that the ANL.GOV ticket may be used. To do this, use the kdestroy(8) command or, on Mac OS X, /System/Library/CoreServices/Kerberos.app . (Anthony Avarca)
Password Policies
The methods described above will grant you, the holder of your Argonne domain password and private ssh key, access to your account on Carbon. As with any Argonne computer system, the following rules apply:
- Keep passphrases and passwords private – do not share them with anyone, including administrators that you know or don't know.
- Keep your private key file private - do not share it with anyone.
- Use a strong passphrase following DOE password regulations.
