Is portmap similar to tcpwrappers?

[StickyBit]

Hi folks,

I'm coming from the Solaris world of things and I would like to know what Portmap is? Is it similar to tcpwrappers?

Thanks,

Stickybit.

It's the rpc service. No, it does not provide access control for tcp based services.

i believe portmap is the equivalent of solaris' rpcbind. Anyway, it listens for rpc requests (NFS) and lets the client know what port the service is sitting on. You would protect portmap using tcpwrappers.

tcpwrappers as in /usr/sbin/tcpd -access control facility for internet services and config files /etc/hosts.allow and /etc/hosts.deny?

Thanks?

jaymzter.
tcpwrappers does not support rpc services over tcp.
RTFM.
From man tcpd:
The program does not work with RPC services over TCP.

marsd:
as per your last post -> RTFM

I submit the following:

#
# hosts.deny This file describes the names of the hosts which are
# *not* allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow. In particular
# you should know that NFS uses portmap!

" You would protect portmap using tcpwrappers..."

I hope I don't have to point out that portmap still
doesn't use tcpd. That's usually what people mean when
they say "tcpwrappers"..

In any case I'd forgotten that some portmaps used the
tcpwrappers acl files and format. Thanks..
