# SSH Key Setup for Homelab Git

## 1. Generate key with custom name

```bash
ssh-keygen -t ed25519 -C "miczek.r@gmail.com" -f ~/.ssh/id_ed25519_private -N ""
```

Creates:
- `~/.ssh/id_ed25519_private` (private – never share)
- `~/.ssh/id_ed25519_private.pub` (public – add to Gitea & GitHub)

## 2. Add to SSH config

Append to `~/.ssh/config`:

```
Host git.zea.lt
  HostName 127.0.0.1
  Port 2222
  IdentityFile ~/.ssh/id_ed25519_private
  IdentitiesOnly yes

Host github.com
  IdentityFile ~/.ssh/id_ed25519_private
  IdentitiesOnly yes
```

## 3. Add public key to remotes

```bash
cat ~/.ssh/id_ed25519_private.pub
```

- **Gitea:** Settings → SSH / GPG Keys → Add Key
- **GitHub:** Settings → SSH and GPG keys → New SSH key

## 4. Trust host keys & push

```bash
ssh-keyscan github.com >> ~/.ssh/known_hosts
ssh-keyscan git.zea.lt >> ~/.ssh/known_hosts

cd /home/miczek/homelab
git push -u origin main
```
