$ /usr/bin/netstat
ip open: Permission denied
can't open mib stream: Bad file number

  rootなら問題無し．
- 原因
  /devices/pseudo/ip6@0:ip6
  /devices/pseudo/ip@0:ip
  のパーミッションがおかしい

$ ls -la /devices/pseudo/ip@0:ip /devices/pseudo/ip6@0:ip6
crw-rw---- 1 root sys 143, 1 Mar 20 03:32 /devices/pseudo/ip6@0:ip6
crw-rw---- 1 root sys 3, 0 Mar 20 03:32 /devices/pseudo/ip@0:ip

- 対処法
  /devices/pseudo/ip@0:ip
  /devices/pseudo/ip6@0:ip6
  のパーミッションを変更する．

# chmod o+rw /devices/pseudo/ip@0:ip /devices/pseudo/ip6@0:ip6
