you have to be root to run nmap for udp scan
but for tcp scan, you should be able to run as anormal user
at least it works for me

How could you know I hadn't tried it? Using nmap is one thing in my job.
You won't get full functionality without being root. It needs to construct
customized packets to detect OS types, for example.

Probably the only thing he can do is TCP scan, which is the easiest job
of nmap.
UDP scan is entirely different (and much tricker). You need the ability
to receive ICMP packets, which requires root. I've written such an utility
myself to monitor the health of the DHCP server in my department.

Have you tried installing nmap on Solaris?
did you ever make it work to scan udp port?
I was only able to run udp scan off linux box

Maybe you can help me out,

Which version of Solaris? It seems to have problems with 2.6. I didn't try
it on 2.6.

that's interesting, seems that my problem was a typical one
there is explanation in nmap 2.53
SOLARIS: If you are trying to scan localhost and getting '/dev/lo0: No such fil
e or directory', complain to Sun. I don't think Solaris can support advanced lo
calhost scans. You can probably use "-P0 -sT localhost" though.
I wonder how you fixed that/.

仔细看看他原来的问题，他要用tcpdump监视网络。这个功能没有root是没法用的。

Thank you for your reply. I tried nmap both as a root and
as a user. I like
the function to guess host's OS.
By the way, I am NOT interested in eavesdroping the
packets in an ethernet, which can be done with a lot of
softwares though. And I don't think nmap or
tcpdump can monitor a network. I am a newcomer in info
security, but I am
not a new comer in OS or TCP/IP.
I will appreciate a reply but I do not 100% trust it
before I do the
experiment by myself.
Anyway, thanks again for your re

Then your system must have a weird (or dangerous/incorrect) setting
which allows normal users to use raw socket, assuming your nmap is
not setuid root (since you claim you are not a new comer in OS).
Oh I was confused by your question. I would have appreciated it if
you had made clear what "cannot read socket" means.
This makes me more confused.

I didn't say I could use fingerprint function as a
non-root. The help
given by nmap is very clear, only root could use stared
functions.
What I meant is that "I can not read some sockets as a
non-root in my linux."
I said I am not good in security, but I will learn it and
read papers in
the winter.
