traceroute doesn't work as a normal user

Hi,
When I use traceroute before, it works as a normal user. However now it
doesn't work as a normal user. As far as I tested only root can use it.
The error message as a normal user is:
----snip----
traceroute: icmp socket: Operation not permitted
----snip end---

What's wrong?? What privilege is necessary or using icmp requres any
privilege? it sounds strange to me.

I use debian linux (testing, sarge)

TIA

When I follow the links I get:
lrwxrwxrwx 1 root root 28 2003-04-07 01:31
/usr/bin/traceroute -> /etc/alternatives/traceroute*
lrwxrwxrwx 1 root root 23 2004-04-03 16:44
/etc/alternatives/traceroute -> /usr/bin/traceroute.lbl*
-rwsr-xr-x 1 root root 18136 2004-03-20 03:41
/usr/bin/traceroute.lbl*
So, traceroute (or at least traceroute.lbl) needs setuid permission.

Thanks for the hint. In my case, traceroute-nanog was installed, and my
link leads to /usr/bin/traceroute-nanog and it makes the problem. I purged
traceroute-nanog and it works fine now.
