## SSH
para executar comandos por ssh que usem o display do servidor, começar por executar:
export DISPLAY=:0

Para mais informações como manter o comando a executar mesmo que termine a sessão de ssh consultar:Screen
### Create key
sem password
criar chaves (publica e privada) no cliente
```
```bash
ssh-keygen -t ecdsa -b 521
Se for necessário controlar o nome do ficheiro
#or
ssh-keygen -t ecdsa -b 521 -f ~/.ssh/key-ecdsa
#substituir ~/.ssh/id_ecdsa/mf-key-ecdsa com o path de destino e o nome pretendido
# o directório tem que existir, por isso se não existir:
# mkdir ~/ssh/id_ecdsa
ssh-keygen -t ecdsa -b 521 -f ~/.ssh/mf-key-ecdsa
copiar a chave para o servidor
ssh-copy-id -i ~/.ssh//mf-key-ecdsa.pub example_user@192.0.2.4
testar o ssh para ver se funcionou (ou seja não pede a password)
ssh example_user@192.0.2.4
se pedir a password e indicar algo semelhante a It is required that your private key files are NOT accessible by others. será necessario rever as permissões do ficheiro indicado na informação Exemplo:
chmod g-rwx,o-rwx ~/.ssh/mf-key-ecdsa
Para adicionar o chave existente no ssh-agent (só necessario se a chave privada for copiada de outro sitio)
```
eval `ssh-agent`
ssh-add pathenomedoficheiro
### Copy public key
Caso o servidor de SSH seja em windows e necessario alterara segraunça do authorized_keys
```bashssh-add ~/.ssh/id_ed25519
ssh-copy-id -i ~/.ssh//ey-ecdsa.pub example_user@192.0.2.4
```
get-acl c:\ProgramData\ssh\ssh_host_dsa_key | set-acl C:\Users\[username]\.ssh\authorized_keys
### Add existing Key
```bash
ssh-add ~/.ssh/key-ecdsa
```
### alias
```bash
Host srv01
HostName srv01.lan
