portmap spoofing in nfsmount
Hi all,
I have implemented portmap spoofing in klibc nfsmount (released as
klibc-0.144) This is basically a vestigial portmap daemon which gets
launched before the mount() call and then just records any transactions
it gets to a file and sends back an affirmative reply.
There are two ways to use it (this belongs in a README file, but it's
too late at night right now):
a) Set a fixed

unable to access xen guest's console
Hello all,
I am new to Xen; I followed a few techtips/technotes from How2forge
and other linux sites to walk me through configuring the following:
- proper installation of xen kernel on a CentOS 5.1 server
- booting into the xen kernel and checking the Dom0 (all is fine):

portmap & tcpwrappers
I don't know if this is RedHat 5.1 specific, but be aware that the version
of portmap distributed is the enhanced (Wietse Venema) version. That's
great, except for two things. The first is documented, but easy to overlook:
"In order to avoid deadlocks, the portmap program does not attempt to look
up the remote host name or user name...The upshot of all this is that only

portmap, bind(), and NIS
Greetings
I'm running an NIS server that I would very much *not* want to be
accessible on some of its interfaces. portmap can be instructed to bind
to specific addresses using the -h flag, but this seems to break ypbind.
ypbind will attempt to find a server by issuing a broadcast rpc request to
the local network. When portmap is not bound to INADDR_ANY, it will not
reply to these requests.

portmap not answering
CentOS 5 updated, Xen host.
The portmap on this machine is somehow "stuck" and I can't figure out why.
I enabled it to be able to mount a remote nfs share. The first hurdle was
that "portmap" didn't appear in the chkconfig list, it was installed with
the initial packages but not added to chkconfig. Took me a while to figure
this out. Adding and starting it up is no

portmap messages under /var/log/messages
I am running Redhat 6.1 as a firewall between a cable modem and my home

Root-NFS not mounting using PXELinux - error 101
I seem to be having trouble getting the NFS root filesystem to mount after
the kernel boots. As per thread from 2002 16 January
(http://www.zytor.com/pipermail/syslinux/2002-January/000028.html), I
double checked my DHCP config files, but to no avail. It cannot seem to
attach to the mountd port on the bootserver. Here is some output from the
kernel:

Do I need portmap, haldeamon & xfs running on dom0?
Hi all
I have a CentOS 5.1 server running Xen and recently installed

On a daily basis I''m getting an email about portmap. haldeamon and xfs
consumming too much resources. The main node, dom0 doesn''t even do

portmap/NIS mystery
Hello all,
I have a server on my private network that is configured as an NIS server
and mapped to a "public" IP address on a firewall. All other TCP ports
(SSH, iperf, you name it) are visible from the outside - but the
portmapper-managed ports (port 111 itself and the YPSERV/YPXFRD ports,
etc.) are not visible from the outside - even though they are alive and

Why portmap is needed for NFSv4 in CentOS6
Hi all,
I have setup a CentOS6.3 x86_64 host to act as a nfs server.
According to RHEL6 docs, portmap is not needed when you use NFSv4, but
in my host I need to start rpcbind service to make NFSv4 works.
My /etc/sysconfig/nfs

# Define which protocol versions mountd
# will advertise. The values are "no" or "yes"

portmap vulnerability?
Are there any known vulnerabilities in portmap (redhat''s
portmap-4.0-7b)? I''ve been receiving a lot of attempts to access the
portmap port on some linuxppc machines I administer by various
machines which clearly have no business with mine, and I wonder if
this is an attempt to break in to my machines.

I understand that during PXE boot, it goes into the pxelinux.cfg and it states:

any host.) If that file is not found, it will remove one hex digit and
