Hi,
I tried both rpm and ldd way and got plenty of services listed. After a quick look I could not find either portmap or telnet (both installed on the system), yet I know they are libwrap supported software.
--> The executable "telnet" is the client. Only "telnetd" is the daemon that is linked against libwrap. But you seem to have a strange system. The suggested syntax works on my SuSE 9.1 and SuSE 9.3 systems. This is SuSE 9.1: hostname:/sbin # ldd portmap linux-gate.so.1 => (0xffffe000) libwrap.so.0 => /lib/libwrap.so.0 (0x40031000) libutil.so.1 => /lib/libutil.so.1 (0x40039000) libc.so.6 => /lib/tls/libc.so.6 (0x4003c000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) hostname:/sbin # rpm -q --whatrequires libwrap.so.0 tcpd-7.6-710 lprng-3.8.25-37 quota-3.11-22 portmap-5beta-728 nfs-utils-1.0.6-103 sendmail-8.12.10-158 openssh-3.8p1-37.17 net-snmp-5.1-80.22 mysql-4.0.18-32.20 Telnetd is not installed. This is SuSE 9.3: hostname:~ # ldd /sbin/portmap linux-gate.so.1 => (0xffffe000) libwrap.so.0 => /lib/libwrap.so.0 (0x40031000) libutil.so.1 => /lib/libutil.so.1 (0x40039000) libc.so.6 => /lib/tls/libc.so.6 (0x4003d000) /lib/ld-linux.so.2 (0x40000000) host:~ # rpm -q --whatrequires libwrap.so.0 tcpd-7.6-715 quota-3.12-4 syslog-ng-1.6.5-10 portmap-5beta-733 nfs-utils-1.0.7-3 openssh-3.9p1-12 cups-client-1.1.23-7 cups-1.1.23-7 xinetd-2.3.13-45.2 net-snmp-5.2.1-5.2 ethereal-0.10.13-2.2 openldap2-2.2.23-6 mysql-4.1.10a-3.4 Here's a way to find statically linked libwrap enabled programs: hostname:~/ strings super_daemon | grep hosts_access hosts_access_verbose @(#) hosts_access.c 1.21 97/02/12 02:13:22 where "super_daemon" is a program that is linked statically with libwrap.
