Code:
BEGIN { # do not put BEGIN on a line by itself
i = 0 # no need to initialize the counter,
# awk does this automatically
}

if (NF == 2) {
currgrp = $1
if ($2 ~ uname) {
netgroups[i] = currgrp # you shoud check if the username matches
i ++ # when NF == 2 too

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 AUTHOR
