Do you _need_ portmapper running? Most people don't.

Can you boot into single user mode and look at /var/log/messages to see if
anything is showing up? 'rpm -V portmap' show any problems?

thanks. I am not getting any "single user mode" option, when the system
boots, I gets only these options on boot loader.

It gives 'e' for edit command before booting
'a' for modify kernel args
'c' for command line.

any idea how can I boots in single user mode.

thanks.

I don't use GRUB, but I've seen these instructions posted often enough:

Hit e to get to the edit mode
You should be on the Kernel line containing /vmlinuz
Hit e again and add a
<space> single
to the end of line and hit Enter key. Example:
kernel (hd0,4)/vmlinuz 1 root=/dev/hda9 mem=128M single
then b to boot into single user mode.

If single does not work, try a 1 instead.

Thanks for your message, I edited boot line (I added single at the end
of the line contains vmlinuz...), then it booted with single user mode,
then I did "chkconfig --del portmap", then I verfied whether portmap
was off or on by "chkconfig -list | grep portmap", I can see it is
deleted, then rebooted again.

Now I stopped portmapper, will I loose any kind of services?. Thanks
again.

Glad to hear that.

Hard to say. _MOST_ people don't need it. The normal uses are for NIS
and NFS. What you could try is

rpm -q --whatrequires portmap

In my case, I get "no package requires portmap" so I could remove the
package. However, you might get one or more package listed, such as

nfs-utils-1.0.1-3.9.2.legacy
redhat-config-nfs-1.0.13-6.legacy

which happen to be two NFS packages. Then, look to see if you are actually
using those packages ('rpm -q nfs-utils' to see what's in there, then 'ps
-auwx' to see if any of them are running).
