Suse 12 - problém s firewallom

Suse 12 - problém s firewallom

Nainštalovali sme si Suse 12 a nevedeli sme sa pripojiť cez putty na ssh. (Boli sme zúfalí.)




Riešenie je: vypnúť firewall

Suse má vlastný firewall (nie firewalld ani iptables, aspoň defaultne po inštalácii nie)

názov firewallu: SuSEfirewall2

1) systemctl status SuSEfirewall2

- bežal

2)systemctl stop SuSEfirewall2

-vypnúť, stopnúť

3) systemctl disable SuSEfirewall2

- aby nenabehol po štarte

4) systemctl status SuSEfirewall2

linux-tiak:~ # systemctl status SuSEfirewall2
SuSEfirewall2.service - SuSEfirewall2 phase 2

a ssh beží:

problém ešte môže byť s tým, že ssh nemá povolené prihlasovanie cez heslo (defaultne)

- zmeníme v sshd configu (/etc/ssh/sshd_config)
