For shells that do not support brace expansion:

Code:
for j in 1_255 2_200; do
  [ ${j%_*} -eq 1 ] && i=1 || i=0
  while [ $i -le ${j#*_} ]; do
    ping -c1 192.168.${j%_*}.$i
    i=$(($i + 1))
  done
done

okey thanks a lot

oidentd_masq.conf

oidentd_masq.conf(5)						File Formats Manual					      oidentd_masq.conf(5)

NAME

       oidentd_masq.conf - oidentd IP masquerading/NAT configuration file.

DESCRIPTION

       If you are using IP masquerading or NAT, oidentd can optionally return a username for connections from other machines.  Support for this is
       specified by calling oidentd with the -m (or --masq) flag and by creating an /etc/oidentd_masq.conf file.

       oidentd can also forward requests for an IP masqueraded connection to the machine from which connection originates by way of the -f option.
       This  will  only  work if the host to which the connection is forwarded is running oidentd with the -P (proxy) flag, or if the host's ident
       daemon will return a valid reply regardless of the input supplied by and the address of the host requesting the info  (some  ident  daemons
       for windows do this, maybe others).

FORMAT

       <IP Address|Hostname>[/<Mask>] <Ident Response> <System Type>

       The  first  field  contains the IP address or the hostname of a machine that IP masquerades through the machine on which oidentd runs.  The
       mask parameter can be either a network mask or a mask in CIDR notation.	A mask of 24 is equivalent to  255.255.255.0,  a  mask	of  16	is
       equivalent to 255.255.0.0, etc.

       The second field specifies the reply that oidentd will return for lookups to the host matching the IP address specified in the first param-
       eter.

       The third field specifies the operating system the machine matching the first parameter is running.

EXAMPLES

       <Host>[/<Mask>]		<Ident Response>    <System Type>
       192.168.1.1		     someone		 UNIX
       192.168.1.2		     noone		 WINDOWS
       192.168.1.1/32		     user1		 UNIX
       192.168.1.0/24		     user3		 UNIX
       192.168.0.0/16		     user4		 UNIX
       somehost 		     user5		 UNIX
       192.168.1.0/255.255.255.0     user6		 UNIX
