Thx Armin, Last time I had a look on a SLES9 box, there were no such list in allow or deny file. It seems that the implementation is a little different with workstation versions (including inetd/xinetd). Do you think this is a complete list of services (with the files in /etc/xinetd.d, of course)?

Is there a list (or a way to find out in a running system) somewhere for libwrap supported services?
--> in SuSE 9.3 at least, there is a list of services and some other information in /etc/hosts.allow On my system it looks like: # /etc/hosts.allow # See `man tcpdX and `man 5 hosts_accessX for a detailed description # of /etc/hosts.allow and /etc/hosts.deny. # # short overview about daemons and servers that are built with # tcp_wrappers support: # # package name | daemon path | token # ---------------------------------------------------------------------------- # ssh, openssh | /usr/sbin/sshd | sshd, sshd-fwd-x11, sshd-fwd-<port> # quota | /usr/sbin/rpc.rquotad | rquotad # tftpd | /usr/sbin/in.tftpd | in.tftpd # portmap | /sbin/portmap | portmap # The portmapper does not verify against hostnames # to prevent hangs. It only checks non-local addresses. # # (kernel nfs server) # nfs-utils | /usr/sbin/rpc.mountd | mountd # nfs-utils | /sbin/rpc.statd | statd # # (unfsd, userspace nfs server) # nfs-server | /usr/sbin/rpc.mountd | rpc.mountd # nfs-server | /usr/sbin/rpc.ugidd | rpc.ugidd # # (printing services) # lprng | /usr/sbin/lpd | lpd # cups | /usr/sbin/cupsd | cupsd # The cupsd server daemon reports to the cups # error logs, not to the syslog(3) facility. # # All of the other network servers such as samba, apache or X, have their own # access control scheme that should be used instead. # # In addition to the services above, the services that are started on request # by inetd or xinetd use tcpd to "wrap" the network connection. tcpd uses # the last component of the server pathname as a token to match a service in # /etc/hosts.{allow,deny}. See the file /etc/inetd.conf for the token names. # HTH, Armin -- Am Hasenberg 26 office: Institut für Atmosphärenphysik D-18209 Bad Doberan Schloss-Straße 6 Tel. ++49-(0)38203/42137 D-18225 Kühlungsborn / GERMANY Email: schoech@iap-kborn.de Tel. +49-(0)38293-68-102 WWW: http://armins.cjb.net/ Fax. +49-(0)38293-68-50
