# 🔍Nessus

Vul. Scanner

1- Starting Nessus:

```
sudo systemctl start nessusd && systemctl --no-pager status nessusd
```

`--no-pager:`don't pip the output to a pager 

> if you don't pipe your output through a pager ( less , more and most), **that output will appear on your screen all at once** and thus you might lose something if said output is bigger than the number of lines of your terminal.
