Checking for CLOSE_WAITs
CLOSE_WAIT Indicates passive close. Server just received first FIN from a client.
netstat -a | grep CLOSE_WAIT | wc -l
ps auxxxx
The -a option tells ps to list the processes of all users.
The -u option tells ps to provide detailed information about each process.
The -x option adds to the list processes that have no controlling terminal, such as daemons, which are programs that are launched during booting (i.e., computer startup) and run unobtrusively in the background until they are activated by a particular event or condition.
