Stop ssh brute force attack using SuSEfirewall

June 22nd, 2009 by

Edit /etc/sysconfig/SuSEfirewall2:

#do not open ssh ports here
FW_SERVICES_EXT_TCP=""
FW_CONFIGURATIONS_EXT=""

#add this rule
FW_SERVICES_ACCEPT_EXT="0.0.0.0/0,tcp,22,,hitcount=3,blockseconds=60,recentname=ssh"

#Restart firewall:
rcSuSEfirewall2 restart

Now attacker will just have three attempts to break in.

SUSE Out Your Tweets!

Thanks to Raul Libório from the openSUSE Marketing Team, you can trick out your Twitter background with your openSUSE Project affiliation (member, ambassador, user). Check out the openSUSE Social Network marketing page to get yours (look under “Sidebars for Twitter”.

You can add the logo itself, or use a program like The GIMP or Inkscape to add the logo to your current background (much like mine, below)
