ssh_scan - Ṣayẹwo Iṣeto Server olupin SSH rẹ ati Afihan ni Lainos
ssh_scan jẹ apẹrẹ afọwọṣe SSH iṣeto-ọrọ ati ọlọjẹ eto imulo fun Lainos ati awọn olupin UNIX, ti atilẹyin nipasẹ Mozilla OpenSSH Aabo Itọsọna, eyiti o pese iṣeduro eto ipilẹ ti oye fun awọn ipilẹ iṣeto SSH bii Ciphers, MACs, ati KexAlgos ati pupọ diẹ sii.
O ni diẹ ninu awọn anfani atẹle:
- O ni awọn igbẹkẹle ti o kere ju, ssh_scan nikan lo Ruby abinibi ati BinData lati ṣe iṣẹ rẹ, ko si awọn igbẹkẹle ti o wuwo.
- O ṣee gbe, o le lo ssh_scan ninu iṣẹ miiran tabi fun adaṣe awọn iṣẹ-ṣiṣe.
- O rọrun lati lo, jiroro ni tọka si iṣẹ SSH kan ki o gba ijabọ JSON ti ohun ti o ṣe atilẹyin ati pe o jẹ ipo eto imulo.
- O tun le ṣe atunto, o le ṣẹda awọn ilana aṣa tirẹ ti o baamu awọn ibeere ilana rẹ pato.
Bii o ṣe le Fi sii ssh_scan ni Lainos
Awọn ọna mẹta lo wa ti o le fi sori ẹrọ ssh_scan ati pe wọn jẹ:
Lati fi sori ẹrọ ati ṣiṣe bi okuta iyebiye kan, tẹ:
----------- On Debian/Ubuntu ----------- $ sudo apt-get install ruby gem $ sudo gem install ssh_scan ----------- On CentOS/RHEL ----------- # yum install ruby rubygem # gem install ssh_scan
Lati ṣiṣe lati inu apoti docker, tẹ:
# docker pull mozilla/ssh_scan # docker run -it mozilla/ssh_scan /app/bin/ssh_scan -t github.com
Lati fi sori ẹrọ ati ṣiṣe lati orisun, tẹ:

Bii o ṣe le Lo ssh_scan ni Lainos
Itọkasi fun lilo ssh_scan jẹ atẹle:
$ ssh_scan -t ip-address $ ssh_scan -t server-hostname
Fun apẹẹrẹ lati ṣayẹwo awọn atunto SSH ati eto imulo ti olupin 92.168.43.198, tẹ:
$ ssh_scan -t 192.168.43.198
Akiyesi o tun le kọja [IP/Range/Hostname] si aṣayan -t
