Hack attempts

["Edwin Dicker" <edwin dicker nl>]

The last two days i got bugged by someone from korea and someone from japan.
his is what i find in my LogWatch :
--------------------- SSHD Begin ------------------------ 


Failed logins from these:
   guest/password from ::ffff:211.119.136.170: 1 Time(s)
   test/password from ::ffff:211.119.136.170: 1 Time(s)

Illegal users from these:
   guest/none from ::ffff:211.119.136.170: 1 Time(s)
   guest/password from ::ffff:211.119.136.170: 1 Time(s)
   test/none from ::ffff:211.119.136.170: 1 Time(s)
   test/password from ::ffff:211.119.136.170: 1 Time(s)

is this a known hack attempt by some sort of program ? because for both
tries the same usernames have been tried to use : guest and test

cheers
