SYNOPSISpcheckd [-l FILE, --logfile FILE] [-m DIR, --mailboxdir DIR] [-p PORT,
--port PORT] [-e LOAD, --emptyload LOAD] [-f NUM, --fork NUM] [-r DIR,
--rundir DIR] [-h HOST, --host HOST] [--nodeamon] [--debug] [--help]
[--version]
DESCRIPTION
This program will open the named UDP port (default: 50110) and listen
for requests. It will send an answer to the requests back to the
client.
There are two types of requests: The mailbox request ('M') will ask the
server about the state of the named mailbox ('0 no mail', '1 mail', '2
new mail', or '3 load too high'). The load request ('L') will ask the
server for the load avarage for the last minute.
The load is returned as an integer which is determined by reading
/proc/loadavg and cutting of everything after the decimal point.
This server is single threaded.
OPTIONS--help Print short command line help.
--version
Print version information.
-l FILE, --logfile FILE
Name of logfile (default: /var/log/popular/pcheckd)
-m DIR --mailboxdir DIR
Directory where all the mailboxes reside. There can be an arbi‐
trary depth of subdirectories beneath this. All mailbox names
sent by the client are relative to this directory.
-p PORT, --port PORT
UDP port to listen to.
-e LOAD, --emptyload LOAD
If the system load average over the last minute is LOAD or
higher, a 'M' request will be answered with '3 load too high'.
In this case pproxy will fake an empty mailbox.
-f NUM, --fork NUM
Fork NUM processes at start of pcheckd. The parent and all the
children will answer requests. The parent doesn't count towards
NUM, so there will be NUM+1 pcheckd processes.
-r DIR, --rundir DIR
Name of run directory. The pid file is saved into this direc‐
tory. (default: /var/run/popular)
-h HOST, --host HOST
Host name or IP number to bind to. This might be needed if you
have several IP numbers on one host. Default is to bind to
INADDR_ANY (0.0.0.0), i.e. to listen to all interfaces.
--nodeamon
Don't run as daemon in the background.
--debug
Enable debug logging. This will log all packets as they are
received and sent.
