SSH :verbinding maken met host localhost poort 22: Verbinding geweigerd
In debian kali probeerde ik ssh te verbinden en kreeg de volgende fout :
SSH: connect to host localhost port 22: Connection refused
Achtergrond :
Ik probeerde ssh te verbinden in debian, ik gebruik kali 2.0 sana
Wat ik heb geprobeerd/daan:
`apt-get install openssh-server`
installed openssh-server and its uptodate
Queried service ssh status
● ssh.service - OpenBSD Secure Shell server
Loaded: loaded (/lib/systemd/system/ssh.service; enabled)
Active: active (running) since Wed 2015-09-23 17:20:36 IST; 36min ago
Main PID: 1594 (sshd)
CGroup: /system.slice/ssh.service
└─1594 /usr/sbin/sshd -D
Reconfigured dpkg-reconfigure openssh-server and it also lead to success
Nu probeerde ik verbinding te maken ssh root@localhost
die root@localhost password vereist, dus wat ik deed was
vi /etc/ssh/sshd_config
en voegde commando toe om root login te weigeren:
Mijn sshd_config als volgt :
What ports, IPs and protocols we listen for Port 22
#Use these options to restrict which interfaces/protocols sshd will bind to
#ListenAddress ::
#ListenAddress 0.0.0.0 Protocol 2
# HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key HostKey /etc/ssh/ssh_host_ed25519_key
#Privilege Separation is turned on for security UsePrivilegeSeparation yes
Nu opnieuw geprobeerd om ssh te verbinden via ´ssh root@localhost´ maar ik kreeg connect to host localhost port 22: Connection refused
Ik dacht dat mijn iptables
het misschien verhinderde dus heb ik het geconfigureerd als :
vim /root/firewall.rules
root@vignesh:~# iptables-save > /root/firewall.rules
root@vignesh:~# iptables -X
root@vignesh:~# iptables -t nat -F
root@vignesh:~# iptables -t nat -X
root@vignesh:~# iptables -t mangle -F
root@vignesh:~# iptables -t mangle -X
root@vignesh:~# iptables -P INPUT ACCEPT
root@vignesh:~# iptables -P FORWARD ACCEPT
root@vignesh:~# iptables -P OUTPUT ACCEPT
root@vignesh:~# iptables-save > /root/firewall.rules
En ik vroeg de iptables-save

Nu probeerde ik opnieuw ssh root@localhost
maar kreeg opnieuw de foutmelding.
Kunt u mij alstublieft vertellen waar ik het onderdeel mis? Hoe kan ik het aangesloten krijgen?
