The Canner is included in the netCannery distribution ready to use. You only have to download it separately if you want to extend it.

4. Does netCannery run on anything but Mac OS X?

Not yet. But the backend canner is open source and runs on Unix, Linux, and Mac OS X.

5. Once I checkout the Canner and customize it, how do I tell netCannery to use it?

In netCannery preferences, fill in the "Override canner command" field with the pathname to your custom canner.

6. Can you help me customize the Canner?

Sure. Just contact us using our feedback form and we'll be glad to help.

7. Can I share snapshots created by other users?

Sure. Snapshots are stored as self-contained .netcan documents. To find the location of one on your system, select the snapshot in the icon view and choose "Show in Finder" from the context menu. You can drop .netcan documents on the application to import them, or use the File->Import command.

8. Can I run the Canner on a central collection machine and share snapshots with multiple users?

Sure. You can run the Canner on one machine and rsync the .netcan archives to any number of users.

9. Do I have to enter my router passwords?

No. netCannery can use your SSH key access. Here is some additional authentication info.

  1. The use of SSH public/private keys for login access is recommended
  • Most networks devices support access via SSHv2.
  • use of public/private keys are preferred over passwords
  • Mac OS X 10.5 (Leopard) has built-in ssh-agent support
  • access can be tested easily from the Terminal
  • allows you to leave password field empty in netCannery for a device
  1. Some network devices only support password access via SSHv2
  • In this case, you will have to enter a password in the password field when making a new snapshot
  1. Some network devices only support SSHv1
  • You'll need to pass the '-1' option to ssh
  • Example: ssh -1 $user@$host
  1. Some network devices only support TELNET
  • You'll need to set the command to use telnet
  • Example: telnet -l $user $host
  1. Connecting through another host first
  • SSH to SSH example: ssh -t host.example.com ssh $user@$host
  • SSH to SSH using SSH Agent to pass keys: ssh -tA host.example.com ssh $user@$host
  • SSH to Telnet example: ssh -t host.example.com telnet -l $user $host

How to setup the SSH agent in MacOSX 10.5 (Leopard)

If you have not generated a public/private key pair that you want to use to access your network device, follow these steps:

  1. Open a Terminal window and generate your public/private key pair. Save it in the default id_dsa file and using a passphrase is recommended.

    ssh-keygen -t dsa

  2. Install the key on your favorite network device. Please see your vendors documentation on how to do this.

  3. Connect once to the device from the Terminal. This will result in a popup asking for your passphrase. Check the box "Remember password in my keychain". Now your key is in the ssh agent and it will read the passphrase from the keychain when it needs it.
