.B \-h

.TP
.BI \-c

.TP
.BI \-r

.TP
.BI \-R
Same as 
.B \-r
but uses reverse dns.
.TP
.BI \-v
Turns on via host checking when forwarding replies.
.TP
.BI \-d
Turns on debugging, multiple
.B -d

.TP

(default
.I  /etc/ser/ser.cfg
).
.TP
.BI \-l " address"
Listens on the specified address/interface. Multiple 
.B \-l
mean listening on multiple addresses. The address format is 
[proto:]address[:port], where proto = udp|tcp and
address = host|ip_address|interface_name. Example: -l localhost, 
-l udp:127.0.0.1:5080, -l eth0:5062.
The default behaviour is to listen on all the ipv4 interfaces.
.TP
.BI \-n " processes\-no"
Specifies the number of children processes forked per interface (default 8).
.TP
.BI \-N " tcp processes\-no"
Specifies the number of children processes forked to handle tcp incoming connections (by default is equal to
.BI \-n
).
.TP
.BI \-b " max_rcv_buf_size"
Maximum receive buffer size which will not be exceeded by the auto-probing procedure even if the OS allows.
.TP
.BI \-m " shared_mem_size"
Size of the shared memory which will be allocated (in Megabytes).
.TP
.BI \-w " working\-dir" 
Specifies the working directory. In the very improbable event that 
.B ser 
will crash, the core file will be generated here.
.TP
.BI \-t " chroot\-dir"
Forces 
.B ser 
to chroot after reading the config file.
.TP
.BI \-u " uid"
Changes the user id under which 
.B ser
runs.
.TP
.BI \-g " gid"
Changes the group id under which
