zenmap gui while starting at unpriviledged user warns, that some functions may be unavailable. The rest one works OK. While starting nmap with root privilesges I fall to error: Starting Nmap 5.21 ( http://nmap.org ) at 2010-03-18 10:24 MSK Initiating ARP Ping Scan at 10:24 dnet: Failed to open device eth0 QUITTING!

Please include the output of `emerge -pv libpcap`. Also, if you run `ifconfig`, is the eth0 interface listed as UP?
emerge -pv libpcap shows: [ebuild R ] net-libs/libpcap-1.0.0-r2 USE="-bluetooth -ipv6" 0 kB Total: 1 package (1 reinstall), Size of downloads: 0 kB eth0 of course is up. Even more: running from unpriviledged user nmap does scan finding everything I need.

Do you have libdnet installed on your system? Could you please post the output of `ldd /usr/bin/nmap`?
No, dev-libs/libdnet is not installed on my system. $ ldd /usr/bin/nmap linux-gate.so.1 => (0xb80a9000) libpcre.so.0 => /lib/libpcre.so.0 (0xb805f000) libpcap.so.1 => /usr/lib/libpcap.so.1 (0xb802f000) libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0xb7fe6000) libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0xb7e9a000) libdl.so.2 => /lib/libdl.so.2 (0xb7e96000) libstdc++.so.6 => /usr/lib/gcc/i686-pc-linux-gnu/4.3.4/libstdc++.so.6 (0xb7da9000) libm.so.6 => /lib/libm.so.6 (0xb7d83000) libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.3.4/libgcc_s.so.1 (0xb7d75000) libc.so.6 => /lib/libc.so.6 (0xb7c2d000) libz.so.1 => /lib/libz.so.1 (0xb7c19000) /lib/ld-linux.so.2 (0xb80aa000)
Is this still a problem with nmap 5.35?

Let's close the bug as WORKSFORME then. If you run into this problem again, feel free to reopen it.
