Subject [users@httpd] 501 - new script kiddie activity
Date Mon, 27 Jan 2003 19:13:50 GMT
request header with control chars looks like

193.144.78.177 - - [27/Jan/2003:20:00:01 +0100] "�" 501 - "-" "-"
217.5.85.153 - - [27/Jan/2003:20:00:09 +0100] "�" 501 - "-" "-"
217.81.181.63 - - [27/Jan/2003:20:00:10 +0100] "�" 501 - "-" "-"
80.146.135.29 - - [27/Jan/2003:20:00:25 +0100] "�" 501 - "-" "-"

and corresponding entries in the error_log
[Mon Jan 27 20:07:58 2003] [error] [client 217.231.252.164] Invalid method in 
request �
[Mon Jan 27 20:08:07 2003] [error] [client 80.144.163.42] Invalid method in 
request �

doing a
grep 501 access_log |wc -l
     344
grep 501 access_log |cut -f 1 -d "-" |sort -u|wc -l
      60

until yet :-
shouldn't be a problem;
server-status shows a few long R
but
 CPU Usage: u.36 s.32 cu0 cs0 - .000151% CPU load
 .00124 requests/sec - 1 B/second - 1140 B/request

critical performance load would be about 1000 rps on this apache server...
