Hello

In my LogWatch report I get many login attacks, many from the same
IP address.

sshd:
   Authentication Failures:
      root (218.232.109.187): 59 Time(s)
      adm (218.232.109.187): 2 Time(s)
      apache (218.232.109.187): 1 Time(s)

      operator (218.232.109.187): 1 Time(s)
   Invalid Users:
      Unknown Account: 43 Time(s)

I have permitRootLogin set to NO, and I use strong passwords, but
can I just add these IP addresses to hosts.deny?
and if so how would I set that up

I had so many problems with the 218.0.0.0/24 domain that I totally blocked the entire domain. I believe this domain is in Korea.

Another that bears blocking completely is 64.0.0.0/24 as its 100%
spam of the non-edible variety.  Ditto for 66.0.0.0/24.

Anybody else have any more to contribute?

Whoa, buddy. The entire 64.0.0.0/8 is NOT a spam source. We have a /19 in that space and we're not spammers. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens vitalstream com - - VitalStream, Inc. http://www.vitalstream.com - - - - Brain: The organ with which we think that we think. - ----------------------------------------------------------------------
