Bug Description

Binary package hint: lsof

To reproduce: start netsend listening on a DCCP socket.

$ netsend dccp receive

Do a lsof | grep netsend

knan@ip:~$ lsof | grep netsend
netsend 25588 knan cwd DIR 252,11 4096 352042 /home/bolso/ak-git/htrosbif
netsend 25588 knan rtd DIR 8,1 4096 2 /
netsend 25588 knan txt REG 8,1 94592 376294 /usr/bin/netsend
netsend 25588 knan mem REG 8,1 1572232 1562251 /lib/libc-2.11.1.so
netsend 25588 knan mem REG 8,1 534832 1561658 /lib/libm-2.11.1.so
netsend 25588 knan mem REG 8,1 136936 1561962 /lib/ld-2.11.1.so
netsend 25588 knan 0u CHR 136,1 0t0 4 /dev/pts/1
netsend 25588 knan 1u CHR 136,1 0t0 4 /dev/pts/1
netsend 25588 knan 2u CHR 136,1 0t0 4 /dev/pts/1
netsend 25588 knan 3u sock 0,6 0t0 685217 can't identify protocol

And the DCCP socket only shows up as "can't identify protocol".

I expected it to show up something like this UDPLITE example instead:

netsend 25572 knan 3u IPv4 681227 0t0 UDPLITE *:6666

knan@ip:~$ lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04

knan@ip:~$ apt-cache policy lsof
lsof:
  Installed: 4.81.dfsg.1-1build1
