hello guys,
I have another question related to Named Pipe.
I have made a "/usr/local/etc/SEC_Log_Pipe " and hang it with SEC so
that SEC can read input text from it;
*cmd1*: /perl -w /usr/local/sbin/sec.pl --conf=xxx.cfg --conf=yyy.cfg
--conf=zzz.cfg -input=/usr/local/etc/SEC_Log_Pipe -intevents/
I need to log some information also in a log file upon successful
execution of one of my defined rule and i wanted to use the same pipe
for writing it.
I wrote the following script <sec_log_out.pl>for writing;
/open(NAMEDPIPE, "+< $filename") or die "fifo $!";
$| = 1;
while (<//NAMEDPIPE>)
{
print $_;
//}
/
and executed it as a background process like this;
*cmd2*: /perl sec_log_pipe.pl >> /var/log/sec_monitor.log &
/
but 2 seperate processes are created. /(lsof/
//usr/local/etc/SEC_Log_Pipe/ shows both processes). One processes is
created by SEC i.e. <cmd1> for taking Input and another by <cmd2> for
logging out data to a log file.
Since, I always execute cmd2 after cmd1 so, logging is working fine, but
SEC is not able to take any input unless I kill the process (cmd2).
action statement in my rule set is;
type=Single
ptype=RegExp
patter=blah,blah
desc=$0
/action= write /usr/local/etc/SEC_Log_Pipe [%u] %s/
Is there a good way to handle read/write operations through named pipe?
Thanks in advance,
