Copy Your Public Key to LC

Copy your public key to an LC *slic machine. If you are a CZ-only user, you'll want to copy your public key to oslic. If you are a CZ+RZ user, you'll want to copy your public key to rzslic. The public key you want on *slic is the same public key file generated on your local machine.

You can copy your key via ssh-copy-id <LC_USERNAME>@<MACHINENAME>.
- If this works, you are done!
- If ssh-copy-id does not work from your local machine, use scp as described in step 2.
Log in to *slic (oslic, rzslic, or cslic) and check to see if you have a file called $HOME/.ssh/authorized_keys.
- If authorized_keys does not exist on *slic, copy your public key file via scp to authorized_keys on *slic.
  - The syntax will look something like
```
scp $HOME/.ssh/id_rsa.pub <LC_USERNAME>@<*slic.llnl.gov>:<LC_HOME_DIR>/.ssh/authorized_keys
```
  - As an example, this might look like
```
scp $HOME/.ssh/id_rsa.pub janeh@rzslic.llnl.gov:/g/g0/janeh/.ssh/authorized_keys
```
- If authorized_keys does exist on *slic,
  - Copy $HOME/.ssh/id_rsa.pub to a file of another name on *slic, using the syntax from the last step. This might look like
```
scp $HOME/.ssh/id_rsa.pub janeh@oslic.llnl.gov:/g/g0/janeh/.ssh/laptop_id_rsa.pub
```
  - While on *slic in $HOME/.ssh, append the contents of the newly created public key file to authorized_keys, via
```
cat <public key filename> >> authorized_keys
```
  For example, you might run
```
cat laptop_id_rsa.pub >> authorized_keys
```
