Re: Re: [suse-security] libwrap supported services

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)?

Hi Petteri,

--> 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.
